Questions | Exam Solutions | Correct Answer Keys
✓ 100% Accurate & Verified Questions and Answers
Question 1
A 68‑year‑old man presents with chest pain; ECG shows a regular narrow‑complex rhythm at
150 bpm with a visible P wave before each QRS. What is the most likely rhythm?
A) Atrial fibrillation
B) Ventricular tachycardia
C) Supraventricular tachycardia (AVNRT)
D) Second‑degree AV block
✓ Correct Answer: Supraventricular tachycardia (AVNRT)
RATIONALE
Regular narrow‑complex tachycardia with 1:1 P‑QRS relationship is typical of SVT.
Question 2
During a cardiac arrest, you have placed an endotracheal tube. Which monitoring method best
confirms correct placement?
A) Chest X‑ray
B) Auscultation of bilateral breath sounds
C) Continuous waveform capnography
D) Pulse oximetry
✓ Correct Answer: Continuous waveform capnography
RATIONALE
Capnography provides immediate, objective confirmation of tracheal placement.
,Question 3
A patient in pulseless ventricular fibrillation receives two 200‑J biphasic shocks but the rhythm
persists. What is the next drug of choice?
A) Lidocaine 1 mg/kg IV
B) Amiodarone 150 mg IV push
C) Epinephrine 1 mg IV
D) Magnesium sulfate 2 g IV
✓ Correct Answer: Epinephrine 1 mg IV
RATIONALE
Epinephrine is administered after the first two defibrillations before antiarrhythmics.
Question 4
After the third shock for refractory VF, which medication should be given next?
A) Lidocaine 1 mg/kg IV
B) Amiodarone 300 mg IV bolus
C) Atropine 1 mg IV
D) Dopamine infusion
✓ Correct Answer: Amiodarone 300 mg IV bolus
RATIONALE
Amiodarone 300 mg is the recommended dose after epinephrine for refractory VF.
, Question 5
A 55‑year‑old woman with acute stroke symptoms arrives 90 minutes after onset; non‑contrast CT
is normal. What is the next step?
A) Begin anticoagulation with heparin
B) Start intravenous tissue plasminogen activator (tPA)
C) Observe and repeat CT in 24 hours
D) Administer aspirin 81 mg PO
✓ Correct Answer: Start intravenous tissue plasminogen activator (tPA)
RATIONALE
tPA is indicated within 3 hours of symptom onset with a normal CT.
Question 6
During BLS, how long should a pulse check last?
A) 2‑3 seconds
B) 5‑10 seconds
C) 15‑20 seconds
D) 30 seconds
✓ Correct Answer: 5‑10 seconds
RATIONALE
Guidelines limit pulse checks to 5‑10 seconds to minimize interruptions.
