A nurse is caring for a male client who reports nausea and vomiting and is receiving IV fluid therapy. His blood urea nitrogen (BUN) is 32 mg/dL, creatinine 1.1 mg/dL, and hematocrit 50%. Which of the following nursing interventions is appropriate?

Choice a) is incorrect because morphine sulfate is an appropriate prescription for a client who has acute heart failure following MI. Morphine sulfate is an opioid analgesic that can relieve pain, anxiety, and dyspnea. Morphine sulfate can also reduce the preload and afterload of the heart, which can improve the cardiac output and oxygenation.

Choice b) is incorrect because laboratory testing of serum potassium is an appropriate prescription for a client who has acute heart failure following MI. Serum potassium is an electrolyte that is important for the normal function of the cardiac cells and muscles. Serum potassium can be altered by various factors, such as renal function, acid-base balance, medications, or dietary intake. Serum potassium can affect the cardiac rhythm and contractility, which can influence the outcome of the client.

Choice c) is correct because 0.9% normal saline IV at 50 mL/hr continuous is a prescription that requires clarification for a client who has acute heart failure following MI. 0.9% normal saline is an isotonic solution that can maintain the fluid balance and blood pressure in the body. However, 0.9% normal saline can also cause fluid overload and worsen the heart failure symptoms, such as edema, crackles, and dyspnea. The nurse should clarify with the provider if this prescription is appropriate for the client's condition and if there are any parameters or limits for the fluid administration.

Choice d) is incorrect because bumetanide 1 mg IV bolus every 12 hr is an appropriate prescription for a client who has acute heart failure following MI. Bumetanide is a loop diuretic that can increase the urine output and reduce the fluid volume and pressure in the body. Bumetanide can also decrease the preload and afterload of the heart, which can improve the cardiac output and oxygenation.

Choice a) is incorrect because nausea is not a common manifestation of ARF. Nausea is a sensation of discomfort in the stomach that may or may not lead to vomiting. Nausea can be caused by many other conditions, such as gastroenteritis, motion sickness, or pregnancy.

Choice b) is correct because severe dyspnea is a common manifestation of ARF. Dyspnea is a subjective feeling of difficulty or discomfort in breathing. Severe dyspnea indicates that the client is not getting enough oxygen and may have low blood oxygen levels (hypoxemia) or high carbon dioxide levels (hypercapnia).

Choice c) is correct because headache is a common manifestation of ARF. Headache is a pain or discomfort in the head, scalp, or neck. Headache can be caused by high carbon dioxide levels (hypercapnia), which can affect the blood vessels and nerves in the brain.

Choice d) is correct because a decreased level of consciousness is a common manifestation of ARF. Level of consciousness is a measure of how alert and oriented a person is. A decreased level of consciousness can be caused by low blood oxygen levels (hypoxemia), high carbon dioxide levels (hypercapnia), or acid-base imbalance, which can affect brain function and mental status.

Choice e) is correct because hypotension is a common manifestation of ARF. Hypotension is a condition in which the blood pressure is lower than normal. Hypotension can be caused by low blood oxygen levels (hypoxemia), which can impair heart function and reduce cardiac output.
