A nurse is auscultating a client's heart sounds and hears an extra heart sound before what should be considered the first heart sound S1. The nurse should document this finding as which of the following heart sounds?

Correct answer: C

A. Bumetanide 1 mg IV bolus every 12 hr is a loop diuretic used to help reduce fluid overload and manage heart failure symptoms. This medication helps remove excess fluid from the body and can be beneficial for a client with acute heart failure following an MI.

B. Laboratory testing of serum potassium upon admission: It is common to monitor serum potassium levels in patients receiving diuretics, especially loop diuretics, to prevent electrolyte imbalances.

C.Administering 0.9% normal saline IV at a continuous rate can potentially exacerbate heart failure by increasing fluid volume, leading to fluid overload and worsening symptoms. In acute heart failure, fluid management is critical, and fluids are typically restricted to prevent further strain on the heart.

D. Morphine sulfate 2 mg IV bolus every 2 hr PRN pain: Morphine sulfate is prescribed for pain management and is commonly used in acute heart failure situations to relieve anxiety and decrease preload on the heart. The dosing frequency is appropriate as "every 2 hr PRN" indicates it should be administered as needed for pain relief.

Correct answer: B

A. "I will take my diuretic before sleep and drink fluids during the day": This statement is not correct. Diuretics are usually taken in the morning to avoid disrupting sleep with increased urination at night. Additionally, fluid intake is generally restricted in congestive heart failure to manage fluid balance.

B. "I plan to slow down if I am tired the day after exercising":This statement reflects an understanding of the need to manage activity levels and recognize the signs of overexertion, which is crucial for clients with congestive heart failure. Pacing activities and allowing for adequate rest can help prevent exacerbations of heart failure symptoms.

C. "I will read food labels and limit my sodium to 4 grams per day": This is incorrect. Limiting sodium intake is a key component of heart failure management. The recommended sodium intake for individuals with heart failure is often much lower than 4 grams per day, typically around 2 grams or less.

D. "I should use naproxen to manage discomfort": Using nonsteroidal anti-inflammatory drugs (NSAIDs) like naproxen can contribute to fluid retention and worsen heart failure symptoms. This statement is not indicative of effective teaching.
