A. 150 mg IV pushj1 j1 j1



B. 300 mg IV bolus
j1 j1 j1



C. 1 mg/min infusion
j1 j1




D. 0.5 mg/kg IV
j1 j1




Correct Answer – B. 300 mg IV bolus
j1 j1 j1 j1 j1 j1 j1



Rationale: During cardiac arrest (VF/pulseless VT), ACLS guidelines recommend an
j1 j1 j1 j1 j1 j1 j1 j1 j1




initial 300 mg IV/IO bolus to stabilize ventricular dysrhythmias by prolonging
j1 j1 j1 j1 j1 j1 j1 j1 j1 j1 j1




myocardial repolarization and reducing automaticity.
j1 j1 j1 j1 j1




2. The med is administrated rapid IV push resulting in a brief flatline, used
j1 j1 j1 j1 j1 j1 j1 j1 j1 j1 j1 j1




for SVT, code cart must be at bedside
j1 j1 j1 j1 j1 j1 j1 j1




A. Metoprolol
B. Diltiazem
C. Adenosine
D. Amiodarone
Correct Answer – C. Adenosine
j1 j1 j1 j1



Rationale: Adenosine transiently blocks AV node conduction and may cause brief
j1 j1 j1 j1 j1 j1 j1 j1 j1 j1




asystole (“flatline”), making it highly effective for SVT conversion. Continuous
j1 j1 j1 j1 j1 j1 j1 j1 j1 j1




cardiac monitoring and resuscitation equipment must be available.
j1 j1 j1 j1 j1 j1 j1




3. what are the doses for adenosine?
j1 j1 j1 j1 j1

,A. 3 mg, 6 mg, 6 mg
j1 j1 j1 j1 j1

Correct Answer – C. 6 mg, 12 mg, 12 mg rapid IV push
j1 j1 j1 j1 j1 j1 j1 j1 j1 j1 j1 j1



Rationale: Standard ACLS dosing: 6 mg rapid push, followed by 12 mg, may repeat
j1 j1 j1 j1 j1 j1 j1 j1 j1 j1 j1 j1 j1




12 mg once if SVT persists.
j1 j1 j1 j1 j1




4. medication used PRN for angina j1 j1 j1 j1




A. Aspirin
B. Nitro
C. Morphine
D. Clopidogrel
Correct Answer – B. Nitro j1 j1 j1 j1




Rationale: Nitroglycerin dilates coronary arteries and reduces preload, decreasing
j1 j1 j1 j1 j1 j1 j1 j1




myocardial oxygen demand. Common adverse effects: headache and
j1 j1 j1 j1 j1 j1 j1 j1




hypotension.


5. Each large box on the ecg paper represents how many seconds
j1 j1 j1 j1 j1 j1 j1 j1 j1 j1




A. 0.04 sec j1




B. 0.10 sec j1



C. 0.20 sec j1




D. 1 second
j1




Correct Answer – C. 0.20 sec j1 j1 j1 j1 j1




Rationale: One large ECG box = 0.20 seconds (five small boxes of 0.04 sec each).
j1 j1 j1 j1 j1 j1 j1 j1 j1 j1 j1 j1 j1 j1




6. two serum lab tests that would be elevated with MI
j1 j1 j1 j1 j1 j1 j1 j1 j1

, A. BNP and D-dimer j1 j1



B. CK and Troponin
j1 j1



C. Potassium and Sodium j1 j1




D. Hemoglobin and Platelets j1 j1




Correct Answer – B. CK and Troponin
j1 j1 j1 j1 j1 j1



Rationale: Troponin is most specific, while CK (CK-MB) rises with myocardial
j1 j1 j1 j1 j1 j1 j1 j1 j1 j1




injury and helps confirm infarction.
j1 j1 j1 j1 j1




7. What complication of CABG presents with manifestations of decreased
j1 j1 j1 j1 j1 j1 j1 j1




urinary output, crackles, jvd, s3 gallop
j1 j1 j1 j1 j1 j1




A. Cardiac tamponade j1



B. Pump failure (heart failure) j1 j1 j1




C. Hypovolemia
D. Pulmonary embolism j1




Correct Answer – B. Pump failure (heart failure)
j1 j1 j1 j1 j1 j1 j1




Rationale: Classic signs of left-sided heart failure include pulmonary congestion,
j1 j1 j1 j1 j1 j1 j1 j1 j1




low cardiac output, oliguria, and S3 gallop.
j1 j1 j1 j1 j1 j1 j1




8. Most carbohydrates in the diet should be complex such as whole grains.
j1 j1 j1 j1 j1 j1 j1 j1 j1 j1 j1
