OSSSC Nursing Officer 2026: 50 Medical-Surgical Nursing MCQs

Question 1. A patient with acute pulmonary edema is severely breathless and anxious. Which position should the nurse prioritize?

A. Supine position

B. High-Fowler's position

C. Trendelenburg position

D. Prone position

Correct Answer: B. High-Fowler's position

Explanation: High-Fowler's positioning helps maximize lung expansion and can reduce venous return to the heart, helping relieve pulmonary congestion. Supine and Trendelenburg positions can worsen respiratory distress in this situation.

Question 2. Which finding is most characteristic of left-sided heart failure?

A. Ascites

B. Peripheral edema only

C. Pulmonary crackles

D. Enlarged liver

Correct Answer: C. Pulmonary crackles

Explanation: Left ventricular failure causes blood to back up into the pulmonary circulation, producing pulmonary congestion and crackles. Ascites, hepatomegaly and marked systemic venous congestion are more closely associated with right-sided heart failure.

Question 3. Which laboratory marker is most specific for myocardial injury?

A. Serum sodium

B. Cardiac troponin

C. Serum amylase

D. Hemoglobin

Correct Answer: B. Cardiac troponin

Explanation: Cardiac troponins are highly sensitive and specific markers of myocardial injury and are central to the evaluation of suspected acute coronary syndrome. Sodium, amylase and hemoglobin do not specifically identify myocardial injury.

Question 4. A patient with angina is prescribed sublingual nitroglycerin. Which instruction is most important?

A. Swallow the tablet immediately

B. Place the tablet under the tongue

C. Take it only after a heavy meal

D. Crush it and mix it with water

Correct Answer: B. Place the tablet under the tongue

Explanation: Sublingual nitroglycerin is placed under the tongue for rapid absorption and relief of anginal symptoms. It should not be swallowed like an ordinary oral tablet because this delays its intended effect.

Question 5. Which electrolyte abnormality is particularly associated with dangerous cardiac dysrhythmias?

A. Hyperkalemia

B. Mild hyperchloremia

C. Mild hypernatremia

D. Low phosphate alone

Correct Answer: A. Hyperkalemia

Explanation: Significant hyperkalemia can alter cardiac conduction and produce potentially fatal dysrhythmias. Electrolyte abnormalities should be interpreted in clinical context, but potassium disturbances are particularly important because of their effects on myocardial electrical activity.

Question 6. Which assessment finding is most suggestive of hypovolemic shock?

A. Bradycardia with warm skin

B. Tachycardia with cool, clammy skin

C. Hypertension with bounding pulse

D. Slow respirations with flushed skin

Correct Answer: B. Tachycardia with cool, clammy skin

Explanation: Hypovolemia reduces circulating volume, causing compensatory tachycardia and peripheral vasoconstriction. The resulting skin may become cool and clammy, while hypotension can develop as shock progresses.

Question 7. Which intervention is a priority for a patient experiencing an acute asthma exacerbation?

A. Encourage vigorous exercise

B. Administer prescribed rapid-acting bronchodilator therapy

C. Restrict oxygen in all cases

D. Place the patient flat

Correct Answer: B. Administer prescribed rapid-acting bronchodilator therapy

Explanation: Rapid-acting bronchodilator therapy is commonly used to relieve acute bronchoconstriction. The nurse should also assess oxygenation and respiratory effort and provide oxygen when clinically indicated.

Question 8. Which breath sound is commonly associated with bronchospasm?

A. Wheezing

B. Pleural friction rub only

C. Stridor from the upper airway only

D. Normal vesicular sounds

Correct Answer: A. Wheezing

Explanation: Wheezing is a high-pitched sound produced by narrowed lower airways and is commonly heard in asthma and other obstructive airway disorders. Stridor usually indicates upper-airway obstruction and requires urgent assessment.

Question 9. A patient with COPD is receiving oxygen therapy. What is the nurse's priority?

A. Ignore respiratory status once oxygen is started

B. Monitor oxygenation and clinical respiratory status

C. Automatically administer the highest oxygen concentration

D. Withhold all prescribed oxygen

Question 11. Which symptom is most characteristic of an upper gastrointestinal bleed?

A. Hematemesis

B. Hematuria

C. Epistaxis only

D. Polyuria

Correct Answer: A. Hematemesis

Explanation: Hematemesis refers to vomiting blood and can occur with upper gastrointestinal bleeding. Depending on the amount and transit time, gastrointestinal bleeding may also produce black, tarry stools known as melena.

Question 12. Which stool characteristic is classically associated with melena?

A. Black and tarry stool

B. Bright green stool only

C. White stool only

D. Hard pellet-like stool

Correct Answer: A. Black and tarry stool

Explanation: Melena is typically black, tarry and often has a characteristic odor because blood has been digested as it passes through the gastrointestinal tract. It commonly indicates an upper gastrointestinal source, although clinical evaluation is necessary.

Question 13. Which nursing assessment is particularly important in a patient with acute pancreatitis?

A. Pain assessment

B. Visual acuity only

C. Hearing assessment only

Explanation: Fever in a patient receiving chemotherapy may indicate serious infection, particularly when neutropenia is present. Prompt assessment and treatment according to institutional protocol are important because infection can progress rapidly.

Question 38. Which adverse effect is particularly important to monitor in a patient receiving opioid analgesics?

A. Respiratory depression

B. Increased visual acuity

C. Excessive hair growth

D. Improved reflexes

Correct Answer: A. Respiratory depression

Explanation: Opioids can suppress the central nervous system and cause respiratory depression, especially at high doses or when combined with other sedating substances. Respiratory rate, depth, oxygenation and level of consciousness should be monitored appropriately.

Question 39. Which assessment is a priority after administering an opioid?

A. Respiratory status and level of consciousness

B. Hair color

C. Nail length

D. Visual field only

Correct Answer: A. Respiratory status and level of consciousness

Explanation: Opioid-related sedation and respiratory depression can become serious complications. Monitoring respiratory status and consciousness helps the nurse identify adverse effects early and respond appropriately.

Question 40. Which medication is commonly used as a reversal agent for opioid-induced respiratory depression?

A. Naloxone

B. Insulin

C. Atropine

D. Furosemide

Correct Answer: A. Naloxone

Explanation: Naloxone is an opioid antagonist used to reverse opioid-induced respiratory depression. Because its duration of action may be shorter than that of some opioids, continued monitoring and repeat treatment may be necessary.

Question 41. Which finding suggests fluid overload?

A. Crackles and rapid weight gain

B. Dry mucous membranes only

C. Poor skin turgor with weight loss

D. Reduced jugular venous pressure

Correct Answer: A. Crackles and rapid weight gain

Explanation: Fluid overload can produce pulmonary congestion, peripheral edema, elevated blood pressure and rapid weight gain. Daily weight measurement is often useful because relatively small changes can represent meaningful fluid accumulation.

Question 42. Which finding is more consistent with dehydration?

A. Dry mucous membranes and decreased urine output

B. Pulmonary crackles and edema

C. Rapid weight gain

D. Elevated jugular venous pressure

Correct Answer: A. Dry mucous membranes and decreased urine output

Explanation: Dehydration can cause dry mucous membranes, thirst, tachycardia, decreased urine output and orthostatic changes. Severe dehydration may progress to hypovolemic shock if fluid losses are not corrected.

Question 43. Which nursing action is appropriate when caring for a patient with a urinary catheter?

A. Maintain a closed drainage system

B. Disconnect the system frequently

C. Place the drainage bag above the bladder

D. Allow tubing to become kinked

Question 44. Which symptom is commonly associated with a urinary tract infection?

A. Dysuria

B. Improved urine flow without symptoms

C. Increased visual acuity

D. Painless hearing loss

Correct Answer: A. Dysuria

Explanation: Dysuria, or painful urination, is a common symptom of lower urinary tract infection. Frequency, urgency and suprapubic discomfort may also occur, while fever and flank pain can suggest upper urinary tract involvement.

Question 45. Which intervention is important for preventing postoperative atelectasis?

A. Deep breathing and coughing exercises

B. Prolonged bed rest without repositioning

C. Avoiding all movement

D. Restricting prescribed respiratory exercises

Correct Answer: A. Deep breathing and coughing exercises

Explanation: Deep breathing, coughing, early mobilization and appropriate use of incentive spirometry can help prevent postoperative atelectasis. These interventions promote lung expansion and secretion clearance.

Question 46. Which postoperative finding requires immediate assessment?

A. Mild expected incisional discomfort

B. Sudden difficulty breathing

C. Mild fatigue

D. Slight thirst

Correct Answer: B. Sudden difficulty breathing

Explanation: Sudden respiratory difficulty can indicate serious complications such as pulmonary embolism, airway obstruction, pneumothorax or severe atelectasis. The nurse should immediately assess airway, breathing and circulation and activate emergency support as required.

Question 47. Which type of wound drainage is typically associated with fresh bleeding?

A. Serous

B. Sanguineous

C. Purulent

D. Fibrinous

Correct Answer: B. Sanguineous

Explanation: Sanguineous drainage is primarily blood and is typically red. Serous drainage is thin and clear or pale yellow, while purulent drainage is generally thick and may indicate infection.

Question 48. Which finding is most suggestive of wound infection?

A. Increasing redness, warmth, pain and purulent drainage

B. A clean, dry incision with decreasing pain

C. Normal wound approximation

D. Mild expected tenderness immediately after surgery

Correct Answer: A. Increasing redness, warmth, pain and purulent drainage

Explanation: Increasing local redness, warmth, swelling, pain and purulent drainage can indicate surgical-site infection. Systemic findings such as fever or worsening clinical status may provide additional evidence of infection.

Question 49. A patient has a serum sodium level significantly below the normal range. Which neurological manifestation may occur?

A. Confusion and seizures

B. Improved concentration

C. Increased hearing ability

D. Increased muscle strength in every case

Correct Answer: A. Confusion and seizures

Explanation: Significant hyponatremia can cause water to shift into brain cells, resulting in neurological symptoms such as headache, confusion, seizures and decreased consciousness. Severe symptomatic hyponatremia requires urgent clinical management.

Question 50. Which principle should guide nursing care when administering high-alert medications?

A. Skip verification because the drug is familiar

B. Follow medication-safety checks and institutional protocols carefully

C. Estimate the dose if the prescription is unclear

D. Administer without checking patient identity

Correct Answer: B. Follow medication-safety checks and institutional protocols carefully

Explanation: High-alert medications can cause serious harm when used incorrectly, so nurses should follow medication verification procedures, patient identification requirements and institutional safety protocols. Unclear prescriptions should be clarified rather than interpreted through guesswork.

OSSSC Nursing Officer 2026 Medical-Surgical Nursing Revision Strategy

After completing these 50 Medical-Surgical Nursing MCQs, candidates should review the questions they answered incorrectly rather than simply checking the final score. A wrong answer often identifies a specific knowledge gap that can be corrected through focused revision.

For example, if cardiovascular questions were difficult, revise heart failure, myocardial infarction, shock, hypertension, dysrhythmias and ECG-related concepts. If respiratory questions caused difficulty, revisit asthma, COPD, pneumonia, pneumothorax, respiratory failure and oxygen therapy.

Renal nursing should include acute kidney injury, chronic kidney disease, dialysis, fluid balance and electrolyte abnormalities. Neurological nursing should cover stroke, seizures, increased intracranial pressure, meningitis and common neurodegenerative disorders.

For endocrine preparation, focus on diabetes mellitus, hypoglycemia, diabetic ketoacidosis, thyroid disorders and adrenal disorders. In gastrointestinal nursing, revise gastrointestinal bleeding, pancreatitis, intestinal obstruction, hepatitis, cirrhosis and inflammatory bowel conditions.

More OSSSC Nursing Officer Preparation Resources

Medical-Surgical Nursing should be combined with other subjects in a structured preparation schedule. The following resources from All Nursing Jobs 4U can be used alongside this quiz:

How to Use These Nursing Exam Questions Effectively

We recommend using a three-step method. First, attempt all 50 questions under timed conditions without checking the answers. Second, calculate the score and classify each incorrect answer according to the topic involved. Third, revise the relevant topic and retake the questions after a short interval.

Instead of memorizing only the correct option, we should understand the clinical principle behind each answer. Competitive nursing examinations can change the wording of a familiar concept, so conceptual understanding is more useful than remembering a single sentence.

We should also pay particular attention to questions involving priority nursing interventions. When an examination question describes an unstable patient, airway, breathing and circulation usually require immediate consideration. However, the exact priority depends on the clinical situation presented in the question.

Frequently Asked Questions About OSSSC Nursing Officer MCQs

Section 1: Quantitative & Clinical Arithmetic Aptitude

Q1. The LCM of two numbers is 720 and their HCF is 120. If one of the numbers is 240, what is the second number?

  • A) 360
  • B) 480
  • C) 280
  • D) 300

Correct Answer: A) 360

Rationale: The formula states that Product of two numbers = LCM × HCF. Therefore, Second Number = (720 × 120) / 240 = 360. Options B, C, and D reflect arithmetic division errors.

Q2. If a nurse needs to distribute 180 ml of oral solution into equal doses using bottles of either 12 ml, 15 ml, or 18 ml capacity without remainder, what is the HCF of these container sizes?

  • A) 6 ml
  • B) 3 ml
  • C) 9 ml
  • D) 15 ml

Correct Answer: B) 3 ml

Rationale: The Highest Common Factor (HCF) of 12 (2²×3), 15 (3×5), and 18 (2×3²) is 3. Option A is a factor of 12 and 18 but not 15, while C and D are not common factors to all three.

Q3. Four alarms in an intensive care unit (ICU) signal at intervals of 6, 8, 12, and 18 seconds respectively. If they chime together now, after how many minutes will they next chime simultaneously?

  • A) 1.2 minutes
  • B) 2.0 minutes
  • C) 1.5 minutes
  • D) 2.4 minutes

Correct Answer: A) 1.2 minutes

Rationale: Find the LCM of 6, 8, 12, and 18, which is 72 seconds. Converting seconds to minutes: 72 / 60 = 1.2 minutes. Options B, C, and D are incorrect conversions.

Q4. Calculate the HCF of the fractional dosages: 3/4, 9/16, and 6/8.

  • A) 3/16
  • B) 9/8
  • C) 3/8
  • D) 1/16

Correct Answer: A) 3/16

Rationale: HCF of fractions = (HCF of Numerators) / (LCM of Denominators). HCF(3, 9, 6) = 3; LCM(4, 16, 8) = 16; thus 3/16. Other choices confuse numerator LCM with HCF rules.

Q5. Determine the LCM of the fractions 4/5, 8/15, and 2/25.

  • A) 8/5
  • B) 8/75
  • C) 4/15
  • D) 16/5

Correct Answer: A) 8/5

Rationale: LCM of fractions = (LCM of Numerators) / (HCF of Denominators). LCM(4, 8, 2) = 8; HCF(5, 15, 25) = 5, yielding 8/5. The remaining options misuse denominator calculations.

Q6. The average patient vitals recorded across 5 clinical rounds were 12, 16, 20, 18, and X. If the arithmetic mean of these 5 readings is 17, find the value of X.

  • A) 19
  • B) 21
  • C) 15
  • D) 17

Correct Answer: A) 19

Rationale: Total sum required = Average × Count = 17 × 5 = 85. Sum of known readings = 12 + 16 + 20 + 18 = 66. X = 85 - 66 = 19.

Q7. In a ward of 10 pediatric patients, 4 patients have an average weight of 15 kg, and the remaining 6 patients have an average weight of 20 kg. What is the overall average weight of all 10 patients?

  • A) 17.5 kg
  • B) 18.0 kg
  • C) 17.0 kg
  • D) 18.5 kg

Correct Answer: B) 18.0 kg

Rationale: Total weight = (4 × 15) + (6 × 20) = 60 + 120 = 180 kg. Overall average = 180 / 10 = 18.0 kg. Option A incorrectly averages 15 and 20 directly without weighting.

Q8. A nursing supervisor purchases 10 units of disinfectant at $25 per unit and 15 units of disinfectant at $35 per unit. What is the weighted average price per unit?

  • A) $30
  • B) $31
  • C) $32
  • D) $29

Correct Answer: B) $31

Rationale: Total cost = (10 × 25) + (15 × 35) = 250 + 525 = $775. Total units = 25. Average price = 775 / 25 = $31. Other options result from unweighted arithmetic shortcuts.

Q9. The average age of 7 consecutive shift hours is 42. What is the value of the earliest (least) shift hour in this sequence?

  • A) 36
  • B) 39
  • C) 38
  • D) 40

Correct Answer: B) 39

Rationale: For consecutive integers, the mean is the middle value (4th term). The terms are 39, 40, 41, 42, 43, 44, 45. The smallest integer is 39.

Q10. The ratio of male to female nursing officers in a hospital is 3:5. If the total strength is 240 staff members, how many additional male officers are needed to make the ratio 1:1?

  • A) 60
  • B) 40
  • C) 80
  • D) 50

Correct Answer: A) 60

Rationale: Total parts = 8. Males = (3/8) × 240 = 90; Females = (5/8) × 240 = 150. To achieve a 1:1 ratio, males must equal females (150). Additional males required = 150 - 90 = 60.

Q11. The ratio of nurse-to-patient in a general medical ward is 2:9. If there are 54 patients, how many nurses are on duty?

  • A) 12
  • B) 10
  • C) 14
  • D) 16

Correct Answer: A) 12

Rationale: Let the multiplier be x. Patients = 9x = 54, so x = 6. Number of nurses = 2x = 2 × 6 = 12. Options B, C, and D are incorrect multiples.

Q12. The present combined age of a head nurse and a staff nurse is 80 years. Five years ago, the head nurse was twice as old as the staff nurse. What is the present age of the head nurse?

  • A) 50 years
  • B) 51.6 years
  • C) 55 years
  • D) 48 years

Correct Answer: B) 51.6 years

Rationale: Five years ago, combined sum was 80 - 10 = 70 years. Ratio H:S was 2:1 (3 parts = 70, so 1 part = 23.33). Head nurse age 5 years ago = 46.66. Present age = 51.66 years.

Q13. In a health survey, 48 out of 160 community members screened positive for hypertension. What percentage of the population is hypertensive?

  • A) 25%
  • B) 30%
  • C) 35%
  • D) 28%

Correct Answer: B) 30%

Rationale: Percentage = (48 / 160) × 100 = 0.3 × 100 = 30%. Options A, C, and D represent calculation inaccuracies.

Q14. Nurse A’s salary is 20% higher than Nurse B’s salary. By what percentage is Nurse B’s salary lower than Nurse A’s salary?

  • A) 20%
  • B) 16.67%
  • C) 15%
  • D) 18.25%

Correct Answer: B) 16.67%

Rationale: Let B = 100, then A = 120. Difference = 20. Percentage lower = (20 / 120) × 100 = 16.67%. A common pitfall is choosing 20% (Option A).

Q15. In a licensure exam, a candidate scores 45% marks and passes by 15 marks above the passing line. If the passing threshold is 120 marks, what are the maximum total marks?

  • A) 300
  • B) 250
  • C) 350
  • D) 400

Correct Answer: A) 300

Rationale: Marks obtained = 120 + 15 = 135. If 45% of total marks = 135, then Total Marks = (135 / 0.45) = 300.
