A cardiopulmonary resuscitation (CPR) instructor is presenting a health care provider CPR course. The instructor reviews the ABCDs of basic CPR, which
Assessment, balloon pump, circulation, and drugs
Airway, breathing, circulation, and defibrillation
Airway, breathing, cardioversion, and diuretics
Adrenalin, Bumex, Cardizem, and Dobutrex
The Correct Answer is B
A. Airway: Ensure the airway is open.
B. Breathing: Provide rescue breaths if the person is not breathing.
C. Circulation: Begin chest compressions to maintain blood flow.
D. Defibrillation: Use an automated external defibrillator (AED) as soon as it's available, especially in cases of shockable rhythms like ventricular fibrillation.

Correct Answer is ["A","C","D"]
Explanation
A. Renal function – Requires follow-up: The client’s BUN is 28 mg/dL (high), and creatinine is 1.5 mg/dL (above normal range). This indicates possible renal hypoperfusion or early acute kidney injury due to decreased cardiac output from worsening heart failure. This needs immediate evaluation to prevent further decline in renal function.
B. Cardiac enzymes – Does NOT require follow-up: Troponin T = 0.06 ng/mL and Troponin I = 0.01 ng/mL, both of which are within normal limits. There is no evidence of acute myocardial infarction, so this finding does not require immediate follow-up.
C. BNP – Requires follow-up: BNP is 800 ng/mL (normal < 100 ng/mL), which is markedly elevated. This is a specific indicator of acute decompensated heart failure, requiring urgent treatment such as diuretics, oxygen, and possibly vasodilators.
D. ECG results – Requires follow-up: The client is in atrial fibrillation with rapid ventricular response (RVR) at a rate of 135/min. This rhythm can reduce cardiac output and increase risk for thromboembolic events. It requires rate control or rhythm conversion and anticoagulation evaluation.
E. Neurologic status – Does NOT require follow-up: The client is alert and oriented ×3, follows commands, and has no neurological deficits. This indicates no current neurologic impairment, so this finding is stable and does not need immediate intervention.
Correct Answer is A
Explanation
A. Hepatomegaly (enlarged liver) is a classic sign of right ventricular failure due to systemic venous congestion.
B. A dry, hacking cough is more commonly associated with left-sided heart failure and pulmonary congestion.
C. Crackles in the lungs result from fluid backing up into the lungs, a hallmark of left-sided heart failure, not right-sided.
D. Dizziness may occur in left-sided failure due to decreased cardiac output and poor cerebral perfusion, but it is not a key feature of right-sided failure.
