1. A nurse caring for a patient with acute respiratory distress notices increasing work of
breathing, oxygen saturation of 86% despite supplemental oxygen, and agitation. What is
the priority nursing action?
A. Document the findings and continue monitoring
B. Encourage the patient to rest quietly
C. Notify the provider immediately and prepare for advanced airway support
D. Reassess the patient in 30 minutes
Correct Answer: C. Notify the provider immediately and prepare for advanced airway
support
Rationale: The patient is showing signs of respiratory failure requiring immediate intervention.
Early escalation and preparation for airway management can prevent deterioration. Delaying
action may place the patient at significant risk.
2. A patient with heart failure reports sudden weight gain of 3 kg over two days. What is
the most appropriate interpretation of this finding?
A. Fluid retention is occurring
B. Muscle mass has increased
C. Nutritional status has improved
D. Medication therapy is fully effective
Correct Answer: A. Fluid retention is occurring
Rationale: Rapid weight gain in heart failure is commonly associated with fluid accumulation
rather than changes in muscle or nutritional status. Early recognition helps prevent worsening
symptoms and hospitalization.
3. Which assessment finding most strongly suggests hypovolemic shock?
A. Bounding pulse and hypertension
B. Bradycardia and warm skin
C. Tachycardia and hypotension
D. Hypertension and flushed skin
Correct Answer: C. Tachycardia and hypotension
,Rationale: Hypovolemic shock results from decreased circulating volume. Compensatory
tachycardia occurs initially, followed by hypotension as volume loss progresses.
4. A nurse is administering high-alert medication. Which action best reflects safe
medication practice?
A. Administer immediately to save time
B. Perform an independent double-check according to policy
C. Ask the patient if the dose appears correct
D. Skip documentation until the end of the shift
Correct Answer: B. Perform an independent double-check according to policy
Rationale: High-alert medications require additional safety measures because errors may cause
serious harm. Independent verification reduces the likelihood of medication-related adverse
events.
5. A patient receiving intravenous antibiotics develops facial swelling and wheezing. What
should the nurse do first?
A. Slow the infusion rate
B. Continue monitoring
C. Document the reaction
D. Stop the infusion and initiate emergency response measures
Correct Answer: D. Stop the infusion and initiate emergency response measures
Rationale: Facial swelling and wheezing suggest a severe allergic reaction. Immediate
discontinuation of the medication and emergency intervention are necessary to maintain airway
and circulation.
6. Which laboratory value requires immediate follow-up in a patient receiving insulin
therapy?
A. Blood glucose 95 mg/dL
B. Blood glucose 140 mg/dL
C. Blood glucose 42 mg/dL
D. Blood glucose 180 mg/dL
Correct Answer: C. Blood glucose 42 mg/dL
Rationale: Severe hypoglycemia is a medical emergency that can rapidly lead to neurological
compromise. Prompt treatment is essential.
7. A patient with chronic kidney disease demonstrates confusion and muscle weakness.
Which electrolyte imbalance is most concerning?
A. Hyperkalemia
B. Hypocalcemia
, C. Hypernatremia
D. Hypomagnesemia
Correct Answer: A. Hyperkalemia
Rationale: Hyperkalemia can lead to life-threatening cardiac dysrhythmias and requires urgent
assessment and intervention, especially in renal impairment.
8. During a shift handoff, which information is most important to communicate first?
A. Planned discharge date
B. Patient dietary preferences
C. Recent life-threatening change in condition
D. Family visitation schedule
Correct Answer: C. Recent life-threatening change in condition
Rationale: Critical clinical changes directly affecting patient safety take priority during handoff
communication.
9. A patient develops chest pain radiating to the left arm and jaw. What is the nurse's
priority action?
A. Encourage ambulation
B. Obtain immediate assessment and activate chest pain protocol
C. Offer oral fluids
D. Reposition the patient and reassess later
Correct Answer: B. Obtain immediate assessment and activate chest pain protocol
Rationale: The symptoms are consistent with possible myocardial ischemia. Early intervention
improves outcomes and reduces cardiac damage.
10. Which patient is at greatest risk for healthcare-associated infection?
A. Young patient with a minor fracture
B. Patient receiving short-term oral antibiotics
C. Patient with an indwelling urinary catheter
D. Patient recovering from a migraine
Correct Answer: C. Patient with an indwelling urinary catheter
Rationale: Indwelling devices provide a pathway for pathogens and significantly increase
infection risk.
11. A patient suddenly becomes difficult to arouse following opioid administration. Which
assessment should be prioritized?
A. Skin integrity
B. Bowel sounds
