1. A patient is admitted to the ICU with a suspected myocardial infarction.
Which cardiac biomarker is most specific for myocardial injury and usually peaks
within 24 hours?
A. CK-MB
B. Myoglobin
C. Troponin I
D. B-type natriuretic peptide (BNP)
Answer: C
Rationale: Troponin I is highly specific to cardiac muscle and remains elevated for several
days, making it the preferred diagnostic marker for myocardial injury.
2. When calculating the Mean Arterial Pressure (MAP) for a patient with a blood
pressure of 110/70 mmHg, what is the result?
A. 80 mmHg
B. 75 mmHg
C. 90 mmHg
D. 83 mmHg
Answer: D
Rationale: MAP is calculated as (Systolic + 2*Diastolic) / 3. Here, (110 + 140) / 3 = 83.33.
,3. An ICU patient is experiencing septic shock. Which of the following is the
priority intervention after fluid resuscitation has failed to maintain a MAP > 65
mmHg?
A. Administration of Broad-spectrum antibiotics
B. Starting a Dobutamine drip
C. Obtaining blood cultures
D. Initiating Norepinephrine infusion
Answer: D
Rationale: In septic shock, norepinephrine is the first-choice vasopressor to maintain
perfusion when fluid resuscitation is insufficient.
4. Which component of the PICO formula represents the ‘I’ when formulating an
evidence-based practice question?
A. Intervention
B. Implementation
C. Investigation
D. Indicator
Answer: A
Rationale: PICO stands for Population, Intervention, Comparison, and Outcome.
5. A patient on a ventilator has an ABG result of pH 7.25, PaCO2 55, and HCO3
24. How should the nurse interpret these results?
A. Metabolic Acidosis
B. Respiratory Acidosis
C. Respiratory Alkalosis
D. Metabolic Alkalosis
Answer: B
Rationale: A pH below 7.35 with a high PaCO2 indicates respiratory acidosis, commonly
seen in hypoventilation.
, 6. The nurse notes a patient’s ventilator high-pressure alarm is sounding. What
is the most appropriate initial action?
A. Silence the alarm and monitor the patient
B. Call the respiratory therapist immediately
C. Increase the oxygen concentration to 100%
D. Check for kinks in the tubing or patient biting the tube
Answer: D
Rationale: High-pressure alarms are often caused by obstructions like kinks, secretions, or
the patient fighting the ventilator.
7. In the hierarchy of evidence, which of the following is considered the highest
level of evidence?
A. Systematic reviews of Meta-analyses
B. Expert Opinion
C. Randomized Controlled Trials
D. Case Control Studies
Answer: A
Rationale: Systematic reviews and meta-analyses of RCTs provide the strongest evidence
for clinical decision-making.
8. A patient with a head injury has a Glasgow Coma Scale (GCS) score of 7. What
is the priority nursing action?
A. Assess pupillary response
B. Prepare for endotracheal intubation
C. Administer IV mannitol
D. Position the patient in Trendelenburg
Answer: B
Rationale: A GCS score of 8 or less indicates a severe brain injury and usually necessitates
airway protection (intubation).
