Correct Answer is B

Explanation

A. Morphine sulfate 2 mg IV bolus every 2 hr PRN pain: This prescription is appropriate for managing pain associated with acute heart failure and MI.

B. Bumetanide 1 mg IV bolus every 12 hr: Bumetanide is a loop diuretic commonly used in heart failure to reduce fluid overload. However, the frequency of administration (every 12 hours) may not be sufficient for managing acute heart failure, where more frequent dosing may be necessary initially.

C. Laboratory testing of serum potassium upon admission: This is a routine and appropriate order to monitor electrolyte balance, especially with the use of diuretics.

D. 0.9% normal saline IV at 75 mL/hr: This is a maintenance IV fluid rate that may be appropriate depending on the client's fluid status. However, it does not directly address acute heart failure.

A. 18% B. 44% C. 36% D. 54%

Correct Answer is D

Explanation

A. 18% is inaccurate

B. 44% is inaccurate

C. 36% is inaccurate

D. According to the Rule of Nines:

Each arm is typically assigned 9% (4.5% for each arm). The chest and abdomen together are assigned 18%.

The upper back is assigned 9%.

The lower back is assigned 9%.

Each leg is typically assigned 18% (9% for each leg). Adding these percentages together for the described burns:

9% (each arm) + 18% (chest and abdomen) + 9% (upper back) + 9% (lower back) = 54%
