Nursing 101 (NURSING101)
1. A patient with crushing substernal chest pain, diaphoresis, and nausea arrives in the
emergency department. What is the nurse's priority action?
A. Administer prescribed aspirin and obtain a 12-lead ECG immediately
B. Encourage oral fluids
C. Schedule an outpatient stress test
D. Place the patient in Trendelenburg position
✅ Correct Answer: A. Administer prescribed aspirin and obtain a 12-lead ECG immediately
Rationale
Acute coronary syndrome requires rapid recognition. Early ECG acquisition (within 10 minutes
when possible), aspirin if not contraindicated, and prompt provider notification improve
outcomes.
2. Which laboratory value is the most specific indicator of myocardial injury?
A. Troponin I
B. Potassium
C. Hemoglobin
D. White blood cell count
✅ Correct Answer: A. Troponin I
Rationale
Troponin I is highly sensitive and specific for myocardial cell injury and is the preferred
biomarker for diagnosing myocardial infarction.
,3. A patient develops sudden unilateral facial drooping, slurred speech, and right arm
weakness. What should the nurse suspect?
A. Acute ischemic stroke
B. Migraine headache
C. Bell's palsy
D. Hypothyroidism
✅ Correct Answer: A. Acute ischemic stroke
Rationale
The sudden onset of focal neurological deficits is characteristic of stroke. Immediate activation
of the stroke protocol is essential.
4. Which assessment finding is most concerning in a patient with heart failure?
A. Progressive dyspnea with bilateral crackles
B. Heart rate of 72 bpm
C. Blood pressure of 118/74 mmHg
D. Capillary refill of 2 seconds
✅ Correct Answer: A. Progressive dyspnea with bilateral crackles
Rationale
These findings indicate worsening pulmonary congestion and possible acute decompensated
heart failure.
5. A patient receiving insulin becomes confused, diaphoretic, and shaky. What is the nurse's
first action?
A. Check the blood glucose level
B. Administer long-acting insulin
C. Restrict fluids
D. Obtain a chest X-ray
,✅ Correct Answer: A. Check the blood glucose level
Rationale
These symptoms suggest hypoglycemia. Confirming blood glucose guides immediate treatment.
6. Which electrolyte imbalance places a patient at the greatest risk for life-threatening
dysrhythmias?
A. Hyperkalemia
B. Mild hyponatremia
C. Hypercalcemia
D. Hypermagnesemia
✅ Correct Answer: A. Hyperkalemia
Rationale
Elevated potassium disrupts cardiac conduction and may lead to ventricular arrhythmias or
cardiac arrest.
7. Which ECG finding is commonly associated with hyperkalemia?
A. Tall peaked T waves
B. ST elevation only
C. Short PR interval
D. Narrow QRS complex
✅ Correct Answer: A. Tall peaked T waves
Rationale
Progressive hyperkalemia produces peaked T waves, widened QRS complexes, and can progress
to ventricular fibrillation or asystole.
8. A patient has a respiratory rate of 8 breaths/min after receiving IV morphine. What is the
nurse's priority intervention?
, A. Administer naloxone as prescribed and support ventilation
B. Encourage deep breathing only
C. Offer oral fluids
D. Reassess in one hour
✅ Correct Answer: A. Administer naloxone as prescribed and support ventilation
Rationale
Respiratory depression is a serious opioid complication requiring prompt reversal and airway
support.
9. Which assessment finding suggests septic shock?
A. Hypotension with tachycardia and altered mental status
B. Bradycardia with hypertension
C. Warm, dry skin only
D. Normal urine output
✅ Correct Answer: A. Hypotension with tachycardia and altered mental status
Rationale
Septic shock is characterized by impaired tissue perfusion despite fluid resuscitation and often
presents with hypotension, tachycardia, altered mental status, and organ dysfunction.
10. Which patient is the highest priority?
A. A patient with oxygen saturation of 84% despite supplemental oxygen
B. A patient requesting pain medication
C. A patient awaiting discharge instructions
D. A patient needing a dressing change
✅ Correct Answer: A. A patient with oxygen saturation of 84% despite supplemental oxygen
Rationale
Airway and breathing take priority under the ABC framework.
