The nurse is assessing a client with left-sided heart failure. Which finding is most concerning?

Correct Answer: C

Rationale: Shortness of breath is most concerning in a client with left-sided heart failure as it indicates pulmonary congestion, requiring immediate intervention. Jugular venous distention (Choice A) is a sign of increased central venous pressure but is not as concerning as pulmonary congestion. Crackles in the lungs (Choice B) are common in heart failure due to fluid accumulation but are not as immediately concerning as severe shortness of breath. Peripheral edema (Choice D) is a manifestation of fluid retention in the body but is less indicative of acute pulmonary distress compared to shortness of breath.

Correct Answer: C

Rationale: A serum ammonia level of 80 mcg/dL is most concerning in a client with cirrhosis as it may indicate hepatic encephalopathy, requiring immediate intervention. High serum ammonia levels can lead to altered mental status, confusion, and even coma. Serum albumin (choice A) is often decreased in cirrhosis but does not require immediate intervention. Serum bilirubin (choice B) elevation is expected in cirrhosis and may not require immediate intervention unless very high. Serum sodium (choice D) within the given range is generally acceptable and does not require immediate intervention.

Correct Answer: C

Rationale: A serum potassium level of 5.5 mEq/L should be closely monitored in a client with chronic heart failure as it may indicate hyperkalemia, requiring intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias in patients with heart failure. Serum creatinine (Choice A) is important to monitor for kidney function but is not the priority in this case. Serum sodium (Choice B) and blood glucose (Choice D) levels are not typically the primary focus when assessing a client with heart failure presenting with respiratory symptoms and crackles in the lungs.

Correct Answer: A

Rationale: The correct answer is A: Widening QRS complexes and flat T waves. In the context of an adult male with delirium tremens and symptoms like tachycardia, diaphoresis, restlessness, and disorientation, the presence of widening QRS complexes and flat T waves on an ECG suggests severe electrolyte imbalance, particularly hypokalemia. This severe electrolyte imbalance can lead to life-threatening arrhythmias such as ventricular tachycardia or fibrillation. Tachycardia and elevated blood pressure (choice B) can be expected in delirium tremens but do not directly indicate a life-threatening condition as widening QRS complexes and flat T waves do. Restlessness and anxiety (choice C) are common symptoms of delirium tremens but do not specifically signify a life-threatening condition. Diaphoresis and dehydration (choice D) are also common in delirium tremens but do not directly point towards a life-threatening electrolyte imbalance as widening QRS complexes and flat T waves do.

Correct Answer: A

Rationale: Observing the perineum is the priority action for the nurse in this situation. It allows the nurse to assess the stage of labor, determine the urgency of the situation, and provide immediate assistance if the baby is indeed about to be delivered. Preparing the delivery room and calling the obstetrician can follow once the nurse has assessed the situation. Administering pain relief may not be the immediate priority when the baby is coming.
