250 Questions Across All Specialties
Complete with Detailed Rationales
Question 1
A 55-year-old male with a history of hypertension and hyperlipidemia presents to
the Emergency Department with crushing substernal chest pain radiating to his left
arm, diaphoresis, and nausea. His pain began 45 minutes ago. What is the priority
nursing action?
A) Administer aspirin and obtain a 12-lead ECG
B) Draw blood for cardiac enzymes
C) Administer oxygen via face mask
D) All of the above
Answer: D
Rationale: The priority for a suspected myocardial infarction is a comprehensive
approach: administer aspirin (chewed), obtain a 12-lead ECG, draw cardiac enzymes,
and administer oxygen if hypoxemic. Rapid assessment and treatment are essential to
reduce mortality. Time is muscle.
Question 2
The patient's ECG shows ST-segment elevation in leads V1-V4. What is the most
likely location of the myocardial infarction?
A) Inferior wall MI
B) Anterior wall MI
C) Lateral wall MI
D) Posterior wall MI
, Page 2 of 77
Answer: B
Rationale: ST-segment elevation in leads V1-V4 indicates an anterior wall myocardial
infarction, typically caused by occlusion of the left anterior descending (LAD) artery.
Anterior wall MIs have a higher risk of complications including heart failure and
cardiogenic shock.
Question 3
What is the most appropriate immediate treatment for an ST-elevation myocardial
infarction (STEMI)?
A) Percutaneous coronary intervention (PCI) within 90 minutes
B) Thrombolytic therapy if PCI is not available
C) Aspirin and antiplatelet therapy
D) All of the above
Answer: D
Rationale: STEMI treatment includes PCI (door-to-balloon time <90 minutes),
thrombolytic therapy if PCI is not available, aspirin, and antiplatelet therapy
(clopidogrel, ticagrelor). The goal is to restore blood flow to the affected artery as
quickly as possible.
Question 4
What is the most important medication to administer immediately for a STEMI?
A) Aspirin
B) Nitroglycerin
C) Morphine
D) Heparin
Answer: A
Rationale: Aspirin is critical for acute MI, reducing mortality by inhibiting platelet
aggregation. It should be administered as soon as possible. Nitroglycerin and morphine
are used for pain relief; heparin is used for anticoagulation.
Question 5
The patient's troponin I level is elevated. What is the significance of this finding?
A) Confirms myocardial injury
B) Confirms heart failure
C) Confirms arrhythmia
D) Confirms pulmonary embolism
, Page 3 of 77
Answer: A
Rationale: Elevated troponin I indicates myocardial injury. It is the most specific and
sensitive biomarker for MI. Troponin levels rise within 3-4 hours of symptom onset and
remain elevated for up to 2 weeks.
Question 6
What is the most appropriate pain management for a patient with an MI?
A) Morphine IV
B) Fentanyl IV
C) Nitroglycerin sublingual
D) Both A and C
Answer: D
Rationale: Morphine IV and nitroglycerin sublingual are used for pain relief in MI.
Morphine reduces pain and anxiety, and nitroglycerin causes vasodilation, reducing
preload and myocardial oxygen demand.
Question 7
A 65-year-old male with a history of recent hip replacement surgery presents with
sudden-onset dyspnea, chest pain, and hemoptysis. His oxygen saturation is 88%
on room air. What is the most likely diagnosis?
A) Myocardial infarction
B) Pulmonary embolism
C) Pneumonia
D) Pneumothorax
Answer: B
Rationale: The classic triad of pulmonary embolism includes sudden-onset dyspnea,
chest pain, and hemoptysis. Risk factors include recent surgery (hip replacement),
immobilization, and malignancy. The patient's hypoxia and risk factors support this
diagnosis.
Question 8
What is the most important initial diagnostic test for suspected pulmonary
embolism?
A) D-dimer
B) CT pulmonary angiography (CTPA)
C) Chest X-ray
D) ECG
, Page 4 of 77
Answer: B
Rationale: CTPA is the gold standard for diagnosing pulmonary embolism. It visualizes
the pulmonary arteries and identifies clots. D-dimer is a screening test; a negative D-
dimer virtually excludes PE in low-risk patients.
Question 9
What is the most appropriate treatment for a confirmed pulmonary embolism?
A) Anticoagulation (e.g., heparin)
B) Thrombolytics (e.g., alteplase) for massive PE
C) Oxygen therapy
D) All of the above
Answer: D
Rationale: Anticoagulation (heparin) is the mainstay of PE treatment. Thrombolytics are
indicated for massive PE with hemodynamic instability. Oxygen therapy is given for
hypoxia.
Question 10
The patient's blood pressure is 80/50 mm Hg with a pulmonary embolism. What
does this indicate?
A) Normal vital signs
B) Massive PE with obstructive shock
C) Hypertension
D) Pain
Answer: B
Rationale: Hypotension indicates massive PE with obstructive shock, which is life-
threatening. This requires immediate thrombolytic therapy or embolectomy. The patient
should be monitored in the ICU.
Question 11
What is the most appropriate treatment for a massive PE with shock?
A) Thrombolytics (e.g., alteplase)
B) Embolectomy
C) Anticoagulation
D) Both A and B
Answer: D
Rationale: Massive PE with shock requires thrombolytics or embolectomy.
