Chronic illness often affects quality of life, requires long-term care, and can have psychosocial and economic impact on the patient and family.
a. Write down about different electrolyes and it values (4mark)
Electrolytes are charged minerals (ions) present in body fluids, which are essential for maintaining fluid balance, acid-base balance, neuromuscular activity, and cellular function.
It is important for nurses to monitor electrolyte levels in patients, as imbalances can lead to life-threatening complications.
The main electrolytes are found in extracellular fluid (ECF) and intracellular fluid (ICF).
Different Electrolytes and Their Normal Values
1️⃣ Sodium (Na⁺)
It is the primary extracellular cation and helps maintain fluid balance, nerve conduction, and muscle contraction.
It plays a key role in maintaining extracellular osmolarity and blood pressure regulation.
It also supports acid-base balance through the sodium-bicarbonate exchange mechanism.
Normal value: 135–145 mEq/L.
Disorders include hyponatremia and hypernatremia, which can cause confusion, seizures, coma.
2️⃣ Potassium (K⁺)
It is the primary intracellular cation and essential for nerve impulse conduction, cardiac rhythm regulation, and muscle function.
It also influences acid-base balance by shifting between intracellular and extracellular compartments.
Potassium is critical for maintaining resting membrane potential of all excitable tissues, including the heart and skeletal muscles.
Normal value: 3.5–5.0 mEq/L.
Imbalances such as hypokalemia or hyperkalemia can lead to life-threatening arrhythmias.
3️⃣ Calcium (Ca²⁺)
It is essential for bone and teeth formation, blood clotting, muscle contraction, and nerve transmission.
Calcium also plays an important role in hormone secretion and enzyme activation.
It helps regulate cardiac electrical activity, influencing the plateau phase of the cardiac action potential.
Normal value: 8.5–10.5 mg/dL.
Disorders include hypocalcemia (tetany, seizures) and hypercalcemia (renal stones, cardiac arrhythmia).
4️⃣ Magnesium (Mg²⁺)
It acts as a cofactor for many enzymatic reactions and supports neuromuscular function and cardiac rhythm.
It also influences parathyroid hormone secretion, thereby indirectly affecting calcium metabolism.
Magnesium is essential for DNA and RNA synthesis and energy production through ATP metabolism.
Normal value: 1.5–2.5 mEq/L or 1.8–3.0 mg/dL.
Imbalances such as hypomagnesemia can cause tetany, seizures, and arrhythmias, while hypermagnesemia can depress neuromuscular activity.
5️⃣ Chloride (Cl⁻)
It is the major extracellular anion and helps maintain osmotic pressure, acid-base balance, and fluid balance.
Chloride is also important in maintaining electrical neutrality of cells by balancing positive cations like sodium.
It is involved in the formation of hydrochloric acid (HCl) in the stomach, which is essential for digestion.
Normal value: 95–105 mEq/L.
Disorders include hypochloremia (metabolic alkalosis) and hyperchloremia (metabolic acidosis).
6️⃣ Bicarbonate (HCO₃⁻)
It is a key component of the body’s buffer system, helping maintain acid-base balance.
It is regulated mainly by the kidneys and is involved in transporting CO₂ in the blood.
Bicarbonate helps neutralize excess acids and is crucial in preventing metabolic acidosis or alkalosis.
Normal value: 22–26 mEq/L.
Alterations in bicarbonate levels are seen in conditions like renal failure, COPD, and diabetic ketoacidosis.
7️⃣ Phosphate (PO₄³⁻)
It is necessary for energy metabolism (ATP formation), bone mineralization, and cellular function.
It also plays a role in acid-base buffering and is important for the structural integrity of cell membranes (as phospholipids).
Phosphate is required for oxygen delivery to tissues via its role in 2,3-DPG (diphosphoglycerate) in red blood cells.
Normal value: 2.5–4.5 mg/dL.
Disorders include hypophosphatemia (muscle weakness, respiratory failure) and hyperphosphatemia (seen in renal failure).
b. Define osmosis and diffusion (4 mark)
Definition of Osmosis
Osmosis is defined as the passage or movement of water molecules from an area of lower solute concentration (higher water concentration) to an area of higher solute concentration (lower water concentration) across a semi-permeable membrane.
It is a passive process that does not require any energy (ATP).
Osmosis continues until equilibrium is reached, where the concentration of solutes on both sides of the membrane becomes equal.
It helps maintain fluid balance between intracellular and extracellular compartments.
It is an essential mechanism for regulating cell volume and preventing cell shrinkage or swelling.
Osmosis also plays a key role in capillary exchange, where water moves between blood plasma and interstitial fluid.
Example: Movement of water into red blood cells or plant root cells.
Definition of Diffusion
Diffusion is defined as the movement of particles (solutes or gases) from an area of higher concentration to an area of lower concentration until equilibrium is achieved.
It is also a passive process that does not require energy (ATP).
Diffusion helps substances like oxygen, carbon dioxide, and nutrients move across cell membranes or in body fluids.
The rate of diffusion depends on temperature, concentration gradient, surface area, and size of molecules.
Diffusion allows for the equal distribution of molecules throughout a given space or medium.
It is a crucial process for gas exchange in lungs, where oxygen diffuses from alveoli to blood and carbon dioxide diffuses from blood to alveoli.
Example: Exchange of oxygen and carbon dioxide between alveoli and blood capillaries in the lungs.
c. Write down complication of intravenous therapy (4 mark)

Severe infiltration can cause tissue damage.
2️⃣ Phlebitis
It is defined as inflammation of the vein at the IV insertion site.
It can be caused by mechanical trauma, chemical irritation, or infection.
Signs include redness, warmth, pain, and palpable cord along the vein.
If left untreated, it may progress to thrombophlebitis.
3️⃣ Extravasation
It occurs when vesicant (tissue-damaging) drugs leak into the surrounding tissue.
It causes severe tissue injury, blistering, necrosis, and ulceration.
Prompt recognition and management are essential to minimize permanent tissue damage.
4️⃣ Infection (Local or Systemic)
Local infection can occur at the IV insertion site, leading to redness, warmth, purulent discharge, and pain.
If bacteria enter the bloodstream, it can cause systemic infection or sepsis, which is life-threatening.
Strict aseptic technique is necessary to prevent this complication.
5️⃣ Hematoma
It is a localized collection of blood under the skin due to vein puncture or trauma.
It presents as bruising, swelling, and discoloration around the IV site.
Large hematomas can cause pain and compression of surrounding tissues.
6️⃣ Air Embolism
It occurs when air enters the vein and travels to the heart or lungs, causing blockage of blood flow.
It is a rare but potentially fatal complication.
Signs include sudden dyspnea, chest pain, cyanosis, hypotension, and loss of consciousness.
Prompt action is needed to prevent cardiovascular collapse.
7️⃣ Speed Shock
It occurs when IV medications are administered too rapidly, causing toxic effects.
Signs include flushing, dizziness, hypotension, irregular pulse, and cardiac arrest.
Nurses must follow proper rate of administration to prevent this complication.
8️⃣ Fluid Overload
It occurs when excessive fluid is infused, especially in elderly or cardiac-compromised patients.
It leads to pulmonary edema, hypertension, dyspnea, crackles in lungs, and distended neck veins.
Careful monitoring of IV rate and fluid balance is required.
9️⃣ Thrombosis
It is the formation of a blood clot inside the vein.
It can obstruct blood flow and may result in pain, swelling, and dysfunction of the affected limb.
There is also a risk of embolism if the clot dislodges.
10️⃣ Allergic Reaction
It may occur due to IV medications, fluids, or latex used in IV equipment.
Symptoms include rash, itching, wheezing, shortness of breath, and in severe cases, anaphylaxis.
Immediate discontinuation of the IV and emergency management is needed.

Nursing Responsibilities in CT Scan
Before Procedure
The nurse should explain the procedure, purpose, and possible sensations (such as warmth from contrast injection) to the patient.
The nurse should assess for allergies to iodine or contrast agents.
It is important to check renal function tests (serum creatinine, BUN) before administering contrast.
The nurse should ensure informed consent is obtained.
The nurse should instruct the patient to be NPO (nothing by mouth) for 4–6 hours before contrast-enhanced CT.
The nurse should remove metal objects, jewelry, or dentures to avoid image artifacts.
During Procedure
The nurse should assist the patient in correct positioning on the CT table.
The nurse should provide privacy and emotional support during the scan.
The nurse should monitor for any signs of contrast reaction (rash, itching, difficulty breathing).
The nurse should ensure that emergency equipment is available in case of an anaphylactic reaction.

e. Cardiac marker studies
Definition
Cardiac marker studies are laboratory tests that measure specific enzymes, proteins, or molecules released into the blood when the heart muscle is damaged.
These markers help in the diagnosis, assessment, and monitoring of patients with suspected acute myocardial infarction (AMI) or other cardiac conditions.
Cardiac markers are an essential component of emergency cardiac care and help guide treatment decisions.
Purpose of Cardiac Marker Studies
To aid in the early diagnosis of myocardial infarction (heart attack).
To assess the extent and severity of cardiac muscle injury.
To differentiate between cardiac and non-cardiac chest pain.
To monitor progression of cardiac disease or response to therapy.
To assist in risk stratification of patients with acute coronary syndrome (ACS).
Types of Cardiac Markers
1️⃣ Troponins (Troponin I and Troponin T)
Troponins are proteins involved in the contractile mechanism of cardiac muscle.
They are the most specific and sensitive markers for myocardial injury.
Troponins appear in the blood 3–6 hours after injury, peak at 12–24 hours, and remain elevated for 7–14 days.
A rise in troponins indicates acute myocardial infarction (AMI) or cardiac muscle damage.
High-sensitivity troponin (hs-Tn) tests can detect very small amounts of cardiac injury and allow earlier diagnosis.
2️⃣ Creatine Kinase-MB (CK-MB)
CK-MB is an enzyme isoform specific to cardiac muscle.
It rises in the blood 4–6 hours after myocardial injury, peaks at 18–24 hours, and returns to normal in 2–3 days.
CK-MB is useful for detecting reinfarction (second heart attack) in patients with recent MI.
It is less specific than troponin but still valuable in certain clinical situations.
Serial measurement of CK-MB helps assess trend and ongoing myocardial damage.
3️⃣ Myoglobin
Myoglobin is a small oxygen-binding protein found in muscle, including cardiac muscle.
It is released rapidly after muscle injury, rising within 1–2 hours of MI and peaking at 6–9 hours.
Myoglobin is a very early marker but is not specific to cardiac muscle — it may be elevated in skeletal muscle injury as well.
It is mainly used to rule out MI in early stages.
A normal myoglobin level in the first few hours after chest pain onset is a strong negative predictor for MI.
4️⃣ B-type Natriuretic Peptide (BNP) and NT-proBNP
BNP and NT-proBNP are hormones released from the ventricles in response to increased pressure and volume overload.
They are used to diagnose and monitor heart failure.
Higher BNP levels correlate with worsening heart failure and poor prognosis.
BNP helps differentiate cardiac from non-cardiac causes of dyspnea.
5️⃣ C-Reactive Protein (CRP) — High Sensitivity (hs-CRP)
hs-CRP is an inflammatory marker that reflects systemic inflammation.
It is not specific for myocardial injury but is useful in predicting cardiovascular risk.
Elevated hs-CRP levels are associated with increased risk of atherosclerosis and coronary artery disease (CAD).
hs-CRP helps in long-term risk assessment for future cardiac events.
Advantages of Cardiac Marker Studies
Provides early and accurate diagnosis of myocardial infarction.
Assists in monitoring therapeutic response and detecting reinfarction.
Helps in risk stratification and prognosis of cardiac patients.
Guides clinical decision-making in emergency settings.
Allows serial measurements to track progression of myocardial injury.
Limitations of Cardiac Marker Studies
Some markers lack cardiac specificity (e.g., myoglobin).
Troponin may be elevated in non-ischemic conditions (e.g., renal failure, myocarditis).
Delay in marker appearance may limit very early diagnosis.
Elevated markers do not indicate the exact location of myocardial injury.
Nursing Responsibilities in Cardiac Marker Studies
Before Sample Collection
The nurse should explain the purpose of the test and the importance of timely blood sampling to the patient.
The nurse should verify doctor’s order and ensure proper test requisition.
The nurse should assess for any contraindications to venipuncture.
The nurse should label the sample correctly and record the time of collection accurately.
The nurse should coordinate with the lab to ensure timely transport of samples, especially for serial marker measurements.
During Collection
The nurse should perform venipuncture using aseptic technique.
The nurse should collect samples in the appropriate tube as per laboratory guidelines (e.g., serum separator tube for troponins).
The nurse should monitor for any signs of bleeding, hematoma, or vasovagal reaction during or after blood draw.
The nurse should reassure the patient and provide emotional support, especially if the patient is anxious about the diagnosis.
After Collection
The nurse should observe the patient for post-venipuncture complications.
The nurse should document time of sample collection and any observations.
The nurse should monitor and report results promptly to the healthcare team.
The nurse should assist in preparing the patient for further interventions based on results (e.g., angiography, thrombolysis).
The nurse should educate the patient and family about the significance of cardiac markers and their role in cardiac care.

Tests may include complete blood count (CBC), autoantibody screening (such as ANA for lupus), thyroid function tests, liver and kidney function tests, and serologic tests for infections.
12️⃣ Skin Scrapings for Parasites
It is a test performed by scraping the skin to identify ectoparasites like scabies mites or lice under the microscope.
Q.5 Write short notes on (any four) [20 mark]
a. OT design
It is the planned and systematic layout of the operation theatre, which ensures a safe, sterile, and efficient environment for performing surgical procedures.
1️⃣ Purpose of OT Design
It is designed to maintain strict sterility and reduce the risk of infection during surgery.
It is also intended to provide an environment that ensures patient safety, comfort for surgical teams, and optimum workflow.
2️⃣ Location of OT
It is generally recommended to place the OT in a strategic location within the hospital, ideally close to ICU and emergency departments for quick patient transfer.
It is usually kept in a separate, controlled zone to minimize traffic and contamination.
3️⃣ Zoning of OT Complex
It is important to know that modern OT design is based on a zoning system to maintain aseptic conditions:
a) Protective Zone
It is the outer zone of the OT complex, including changing rooms, waiting areas, and administrative offices.
It is where staff and patients are prepared before entering the sterile areas.
b) Clean Zone
It is the intermediate zone that includes preoperative areas, storage rooms, and scrub stations.
It helps reduce the risk of contaminants entering the sterile area.
c) Sterile Zone
It is the innermost zone where actual surgeries are performed.
It consists of the operating room(s), sterile supply areas, and instrument preparation zones.
Strict aseptic techniques are maintained here.
d) Disposal Zone
It is the area for waste disposal and decontamination after surgery.
Used instruments and materials are processed here.
4️⃣ Design of the Operating Room
It is essential to ensure that the operating room has adequate space to accommodate surgical equipment, staff, and patient care devices.
The size of an operating room is usually around 400–600 square feet depending on the type of surgeries performed.
It is recommended that walls, ceilings, and floors be made of smooth, seamless, and washable materials to prevent contamination.
The room should have proper ventilation, usually with HEPA filters and positive pressure airflow, to ensure clean air circulation.
It is important to install adequate lighting, including shadowless operating lights directly over the surgical field.
It is also necessary to ensure that electrical outlets and gas pipelines (oxygen, nitrous oxide, suction) are safely and conveniently placed.
5️⃣ Ventilation System
It is crucial that the OT has a well-designed ventilation system to maintain positive air pressure, which prevents contaminated air from entering the sterile zone.
It is recommended to maintain 20–25 air changes per hour with HEPA filtration.
It is also important to maintain the temperature (20–24°C) and humidity (50–60%) at appropriate levels.
6️⃣ OT Traffic Control
It is important to control traffic flow in and out of the OT to minimize contamination risk.
There should be dedicated entry and exit points for staff and equipment.
It is advised to have restricted access to the sterile zone, with strict adherence to gowning and hand hygiene protocols.
7️⃣ Essential Components of OT Design
The following elements must be included in the OT design:
Operating table → Adjustable, radiolucent table for surgical procedures.
Shadowless lights → For optimal illumination of the surgical field.
Anesthesia machine → For safe administration of anesthesia.
Surgical instrument trolley → To hold sterile surgical instruments.
Suction apparatus → For clearing blood and secretions during surgery.
Monitors and displays → For continuous patient monitoring.
Handwashing stations → With elbow-operated taps near the entry to the sterile zone.
8️⃣ Safety Features
It is important to include fire safety measures, including fire-resistant materials and accessible fire extinguishers.
Electrical systems should be isolated and grounded to prevent electrical hazards.
Adequate backup power supply must be ensured to avoid interruptions during surgery.
b. Anesthesia
Definition
It is defined as a temporary and controlled loss of sensation or awareness, which is produced by administering anesthetic agents through various routes.
It is used to allow patients to undergo surgical procedures or painful diagnostic interventions without discomfort or memory of the event.
Purpose of Anesthesia
It is mainly given to relieve pain (analgesia), to prevent awareness during the procedure (amnesia), and to achieve muscle relaxation for better surgical access.
It also helps in maintaining patient safety, physiological stability, and psychological comfort during invasive procedures.
Types of Anesthesia
It is classified into four major types based on the extent of sensation loss and the method of administration:
a) General Anesthesia
It is a type of anesthesia that causes complete loss of consciousness and total body sensation, rendering the patient unaware and unresponsive.
It is administered through inhalational agents or intravenous drugs.
It is used for major surgical procedures such as abdominal, thoracic, cardiac, or neurological surgeries.
b) Regional Anesthesia
It is a technique where sensation is blocked in a specific region of the body by administering anesthetic agents near nerve pathways.
It includes:
Spinal anesthesia → Injected into the subarachnoid space to block lower body sensation.
Epidural anesthesia → Injected into the epidural space, used for labor analgesia and lower limb surgeries.
Nerve block → Injected around a specific nerve or nerve plexus to block sensation in a targeted body area.
c) Local Anesthesia
It is a type of anesthesia that produces loss of sensation in a small, localized area without affecting consciousness.
It is often used for minor surgical or dental procedures, wound suturing, or skin biopsies.
d) Conscious Sedation (Monitored Anesthesia Care)
It is a controlled state of depressed consciousness where the patient is relaxed but awake and can respond to commands.
It is used for procedures such as endoscopy, minor orthopedic interventions, and diagnostic imaging.
Stages of General Anesthesia
It is important to know that general anesthesia progresses through four stages:
Stage I (Analgesia) → The patient experiences pain relief and drowsiness but is still conscious.
Stage II (Excitement) → The patient may show irregular breathing, involuntary movements, and increased heart rate.
Stage III (Surgical Anesthesia) → The patient reaches a state of deep unconsciousness, suitable for surgical procedures; reflexes are lost and muscles are relaxed.
Stage IV (Overdose) → It is a dangerous stage of respiratory and cardiovascular depression, which must be avoided.
Common Complications of Anesthesia
It is necessary to monitor the patient for the following complications:
Nausea and vomiting postoperatively are very common.
Sore throat may occur due to intubation.
Allergic reactions to anesthetic agents may develop.
Respiratory depression and hypotension may occur if anesthesia is not well balanced.
In rare cases, malignant hyperthermia, a life-threatening condition, can develop.
Awareness during anesthesia is a rare but concerning complication that should be avoided through proper dosing.
1️⃣ Pre-Anesthesia Responsibilities
It is important for the nurse to conduct a complete pre-anesthetic assessment, including medical history, allergies, current medications, previous anesthesia experiences, and baseline vital signs.
It is the nurse’s duty to verify that the patient has maintained NPO status (nothing by mouth) for the required number of hours to prevent aspiration risk during anesthesia.
It is important to obtain informed consent for the procedure and anesthesia and ensure that all consent forms are correctly signed and documented.
The nurse should provide emotional support and psychological preparation, addressing any fears or concerns expressed by the patient.
It is necessary to ensure that jewelry, dentures, contact lenses, makeup, and nail polish are removed before shifting the patient to the operating room.
2️⃣ Intra-Anesthesia Responsibilities
It is the nurse’s responsibility to assist the anesthetist during induction, maintenance, and emergence from anesthesia.
It is very important for the nurse to continuously monitor vital signs, including heart rate, respiratory rate, blood pressure, oxygen saturation, and ECG readings, throughout the procedure.
It is essential to observe the patient for signs of anesthesia complications, such as allergic reactions or respiratory depression.
The nurse should assist in airway management, including positioning, suctioning, and providing oxygen as required.
It is necessary to maintain aseptic technique to prevent infection during the procedure.
3️⃣ Post-Anesthesia Responsibilities
It is important to transfer the patient to the Post-Anesthesia Care Unit (PACU) safely and position the patient to maintain an open airway (often in the lateral position initially).
The nurse must perform frequent monitoring of vital signs until the patient is fully awake and stable.
It is necessary to assess the patient for return of protective reflexes (gag, cough) and readiness for oral intake.
The nurse should manage pain effectively by administering prescribed analgesics and evaluating their effectiveness.
It is essential to monitor for postoperative nausea and vomiting and administer antiemetic medications if prescribed.
The nurse should encourage early ambulation when appropriate to prevent complications such as deep vein thrombosis (DVT) and atelectasis.
c. Fracture
Definition of Fracture
Fracture is defined as a break or disruption in the continuity of a bone, either partial or complete.
It may occur due to direct trauma, twisting injury, repetitive stress, or disease-related weakness.
Fracture healing depends on factors such as age, nutritional status, and blood supply to the bone.
Etiology
Trauma / injury (fall, accident)
Osteoporosis
Bone tumors
Overuse / stress fractures
Congenital bone diseases
Types of Fracture
1️⃣ Closed (Simple) Fracture
The bone breaks but does not pierce the skin.
It is less prone to infection.
Example: Hairline fracture of tibia after a fall.
2️⃣ Open (Compound) Fracture
The broken bone end protrudes through the skin, causing an open wound.
It carries a high risk of infection and requires urgent surgical care.
Example: Compound fracture of femur in a road traffic accident.
3️⃣ Comminuted Fracture
The bone is shattered into multiple fragments.
It usually results from high-energy trauma such as car crashes.
Example: Comminuted fracture of femur after a crush injury.
4️⃣ Greenstick Fracture
One side of the bone bends, while the other side breaks.
It is commonly seen in children due to soft, flexible bones.
Example: Greenstick fracture of radius in a child after a playground fall.
5️⃣ Transverse Fracture
The fracture line is horizontal across the bone.
It occurs commonly due to direct blow or bending forces.
Example: Transverse fracture of the humerus after a direct fall.
6️⃣ Oblique Fracture
The fracture line runs at an angle across the bone.
It is caused by a rotational or twisting force.
Example: Oblique fracture of fibula due to sports injury.
7️⃣ Spiral Fracture
The bone is twisted apart, producing a helical fracture line.
It is commonly caused by rotational forces, often in sports.
Example: Spiral fracture of tibia from skiing accident.
8️⃣ Impacted Fracture
The broken ends of the bone are driven into each other.
It is commonly seen in arm or leg injuries due to falls.
Example: Impacted fracture of femoral neck in an elderly patient.
9️⃣ Compression Fracture
The bone is compressed or crushed, leading to collapse.
Commonly occurs in vertebrae of elderly patients with osteoporosis.
Example: Compression fracture of thoracic vertebrae in an osteoporotic patient.
10️⃣ Pathological Fracture
It occurs in a bone weakened by disease, such as cancer, infection, or osteoporosis.
It may happen with minimal trauma or spontaneously.
Example: Pathological fracture of femur in a patient with bone metastasis.
Clinical Manifestations
Pain at the fracture site
Swelling and bruising
Deformity or abnormal positioning
Loss of function or movement
Crepitus (grating sound on movement)
Shortening of the affected limb
Diagnostic Evaluation
History collection

X-ray (confirm fracture and type)
CT scan / MRI for complex fractures
Bone scan for stress fractures
CBC if blood loss suspected
Medical Management of Fracture
1️⃣ Initial Assessment & Stabilization
The patient is assessed for life-threatening injuries (ABCs) first.
The fractured limb is immobilized using splints or traction to prevent further damage.
Neurovascular checks are done frequently.
2️⃣ Pain Management
Analgesics such as paracetamol, NSAIDs, or opioids are used as needed.
Positioning and cold application help reduce pain and swelling.
3️⃣ Reduction of Fracture
Closed reduction is performed for simple fractures under sedation or anesthesia.
Open reduction is required for complex or displaced fractures, followed by internal fixation.
4️⃣ Immobilization
It includes cast application, splinting, or external fixation.
Immobilization duration depends on type of fracture, age, and healing potential.
5️⃣ Surgery (ORIF)
Open reduction and internal fixation are used for unstable fractures.
Devices such as plates, screws, intramedullary rods, or external fixators are used to maintain alignment.
6️⃣ Rehabilitation
Physical therapy begins with range of motion (ROM) exercises as soon as possible.
It helps in preventing stiffness, muscle atrophy, and regaining strength.
7️⃣ Prevention of Complications
Measures include infection control, DVT prophylaxis, and pressure ulcer prevention.
The patient is monitored for compartment syndrome and delayed union or nonunion of the fracture.
Nursing Management of Fracture Patient
1️⃣ Pain Management
Pain level is assessed regularly using a pain scale.
The nurse provides analgesics as prescribed and ensures comfortable limb positioning.
Cold packs are applied in the acute phase to reduce swelling.
2️⃣ Immobilization Care
The nurse ensures the cast or splint is properly positioned and not too tight.
The patient is educated on cast care and signs of complications.

d. Diptheria
Definition
Diphtheria is an acute, contagious bacterial infection caused by Corynebacterium diphtheriae, which primarily affects the mucous membranes of the throat and nose, producing a toxin that can cause systemic effects, particularly damage to the heart and nervous system.
Toxigenic strains produce exotoxin responsible for systemic toxicity
Mode of Transmission
Droplet infection (coughing, sneezing)
Direct contact with respiratory secretions, skin lesions
Fomites (rare)
Incubation Period
Typically 2 to 5 days
Pathophysiology
Corynebacterium diphtheriae enters through the respiratory tract.
Bacteria attach to mucosa and produce exotoxin.
Toxin inhibits protein synthesis by blocking EF-2.
Causes local cell death and necrosis.
Pseudomembrane forms over tonsils/throat.
Toxin enters bloodstream, spreads systemically.
Affects heart (myocarditis), nerves (neuritis), and kidneys (tubular damage).
Clinical feature
Sore throat and mild fever
Thick grayish-white pseudomembrane over tonsils, pharynx, or larynx
Difficulty swallowing (dysphagia)
Hoarseness or voice change
“Bull neck” appearance due to swollen lymph nodes and neck edema
Breathing difficulty (if airway is blocked)
Foul-smelling breath
Diagnostic Evaluation
History collection
Physical examination
Throat swab culture on Löffler’s or tellurite medium
Elek’s test for toxin detection
PCR for gene encoding diphtheria toxin
CBC : leukocytosis
Management
Diphtheria Antitoxin (DAT)
Diphtheria Antitoxin (DAT) is administered immediately to neutralize the circulating diphtheria toxin — it is the most important early treatment and should be given even before lab confirmation.
Antibiotic therapy
Antibiotic therapy is initiated with Penicillin G or Erythromycin for 14 days to eradicate the bacteria and prevent further toxin production.
Airway monitoring and supportive care
Airway monitoring and supportive care are provided — nurses should watch for signs of airway obstruction, be prepared for emergency airway management, and implement strict isolation to prevent the spread of infection.
Nursing management
Maintain airway patency; monitor for signs of airway obstruction
Administer oxygen therapy as needed
Give prescribed antibiotics and diphtheria antitoxin promptly
Monitor for signs of myocarditis (e.g., arrhythmias, chest pain)
Maintain strict isolation precautions to prevent spread
Provide nutritional support – soft, high-calorie diet
Monitor fluid and electrolyte balance
Educate patient and caregivers about hygiene and infection control
Provide psychological support to reduce anxiety
Observe for neurological complications (e.g., paralysis, cranial nerve involvement)
Perform frequent oral care to prevent secondary infection in the throat
Position patient in semi-Fowler’s to ease breathing
Assist with suctioning if excessive secretions present
Encourage bed rest during the acute phase to prevent cardiac stress
Complications
Myocarditis
Respiratory failure
Peripheral neuritis (e.g., palatal or limb paralysis)
Renal failure
Death (due to airway obstruction or toxin effects)
e. Nephrosis
Definition
Nephrosis (also known as Nephrotic Syndrome) is a non-inflammatory kidney disorder characterized by massive proteinuria (3.5 g/day), hypoalbuminemia, hyperlipidemia, and edema, due to damage to the glomerular filtration barrier.
Injury to glomerular podocytes and basement membrane.
Increased glomerular permeability to proteins.
Loss of albumin in urine (proteinuria).
Decreased plasma oncotic pressure → edema.
Liver compensates by increasing lipoprotein synthesis → hyperlipidemia.
Clinical manifestations
Edema (periorbital, pedal, generalized)
Frothy urine (due to proteinuria)
Hypoalbuminemia
Hyperlipidemia & lipiduria
Weight gain
Fatigue & weakness
Oliguria (less urine output)
Recurrent infections
Thromboembolic risk (e.g., DVT)
Mild hypertension
Diagnostic Evaluation
History collection
Physical examination
Urine analysis – massive proteinuria
Serum albumin – low
Serum cholesterol & triglycerides – high
Renal function tests
Renal biopsy (to identify the underlying cause)
Management
Corticosteroids
Corticosteroids such as Prednisolone are the first-line treatment, especially in children with minimal change disease, as they help reduce inflammation and protein loss through the kidneys.
Diuretics
Diuretuics like Furosemide are prescribed to manage fluid overload and reduce edema by promoting excretion of excess water through the urine.
Angiotensin-converting enzyme (ACE)
(ACE) inhibitors or Angiotensin II receptor blockers (ARBs), such as Enalapril or Losartan, are used to reduce intraglomerular pressure and minimize proteinuria.
Statins
Statins like Atorvastatin may be given to manage hyperlipidemia associated with nephrotic syndrome and reduce cardiovascular risk.
Anticoagulants
Anticoagulant such as Heparin or Warfarin are considered if the patient has a high risk of thromboembolic events, as nephrosis can create a hypercoagulable state.
In steroid-resistant cases
In this cases immunosuppressive drugs such as Cyclophosphamide, Cyclosporine, or Tacrolimus are administered to control the underlying immune-mediated damage to the glomeruli.
Dietary management
It includes a moderate intake of protein to replace urinary losses without overburdening the kidneys, a low-sodium diet to control edema, and adequate calorie intake to maintain nutritional status.
Nursing management
Monitor vital signs, daily weight, and intake/output (I/O)
Assess and document edema (periorbital, pedal, sacral)
Administer prescribed medications (steroids, diuretics, ACE inhibitors)
Maintain low-sodium and moderate-protein diet
Prevent infection with proper hygiene and isolation if needed
Watch for signs of thromboembolism (e.g., leg pain, swelling)
Educate about disease, medication adherence, and follow-up
Provide emotional and psychological support to patient and family
Monitor for adverse drug reactions (GI upset, immune suppression)
Promote adequate rest and activity balance
Encourage fluid restriction if ordered by physician
Support skin care to prevent breakdown due to edema
Encourage compliance with lab tests (urine protein, serum albumin, lipids)
Coordinate with dietitian and social worker for holistic care
Maintain aseptic technique during any invasive procedures
Complications
Acute kidney injury
Infections (peritonitis, cellulitis)
Thromboembolism (DVT, renal vein thrombosis)
Hypertension
Chronic kidney disease
Q.6 Define following terms (any three) [6 mark]
a. Tracheostomy
Tracheostomy is a surgical procedure that involves creating an opening (stoma) in the anterior wall of the trachea (windpipe) to insert a tracheostomy tube, allowing direct access to the airway for breathing, suctioning, or mechanical ventilation, especially in cases of airway obstruction, respiratory failure, or prolonged intubation.
b. Hypophysectomy
Hypophysectomy is a surgical procedure involving the removal of the pituitary gland (hypophysis), usually performed to treat pituitary tumors, Cushing’s disease, or other hormonal disorders, and is commonly done through a transsphenoidal (nasal) approach or sometimes via a craniotomy.
c. Cystectomy
Cystectomy is a surgical procedure involving the removal of all or part of the urinary bladder, most commonly performed to treat bladder cancer, and may be classified as partial cystectomy (removal of a portion) or radical cystectomy (removal of the entire bladder along with surrounding structures like lymph nodes, prostate in males, or uterus in females).
d. Emphysema
Emphysema is a chronic obstructive pulmonary disease (COPD) characterized by permanent enlargement and destruction of the alveoli (air sacs) in the lungs, leading to reduced surface area for gas exchange, air trapping, and progressive breathlessness.
