In biventricular heart failure, which statement is true?
The ventricles take turns pumping. When one side stops pumping, the other takes over.
Only the left ventricle is affected
The ejection fraction is typically above 50%
Both ventricles are affected, and the ejection fraction can be extremely low.
The Correct Answer is D
A. The ventricles work simultaneously, not alternately, and both failing leads to compromised cardiac output.
B. Biventricular heart failure involves both the left and right ventricles, not just the left.
C. An ejection fraction above 50% is considered normal; in heart failure, especially biventricular, it is often reduced.
D. Biventricular heart failure means both ventricles are impaired, often resulting in a significantly reduced ejection fraction and poor cardiac function.

Correct Answer is D
Explanation
A. Distended abdomen is more commonly associated with right-sided heart failure due to liver congestion and ascites.
B. Anorexia can be a nonspecific symptom and is not a primary indicator of left-sided heart failure.
C. Weight gain and edema in both legs are typical signs of right-sided heart failure, caused by systemic venous congestion.
D. Breathlessness (dyspnea) accompanied by crackles and wheezes indicates pulmonary congestion and fluid buildup, which are classic signs of left-sided heart failure where the heart fails to effectively pump blood out to the body, causing fluid to back up into the lungs.
Correct Answer is A
Explanation
A. Initiate isolation precautions — This is the first action the nurse should take. Bacterial meningitis is highly contagious (often spread via droplet transmission), and immediate isolation (droplet precautions) helps prevent spread to others.
B. Administer antibiotics after collecting cultures — This is a critical next step, but only after the client is placed in isolation to protect others.
C. Prepare for a lumbar puncture after ruling out increased ICP — While a lumbar puncture is important for diagnosis, increased ICP must be ruled out first, and this is not the immediate first action.
D. Start IV fluids — Supportive care is important, but it is not the priority over infection control measures.
