A nurse is reviewing the laboratory values for a client who has heart failure and is taking bumetanide for diuresis. For which of the following results should the nurse notify the provider?

Potassium 2.3 mEq/L (3.5-5)

Magnesium 14 mEq/L (1.3-2.1)

Carcum to mg/dL (9.9-10.5)

Sodium 136 mEq/L (136-145)

Answer and Explanation

The Correct Answer is A

A. Potassium 2.3 mEq/L (3.5-5.0): This is a severely low potassium level (hypokalemia), which can cause dangerous arrhythmias, especially in a client with heart failure. Bumetanide is a loop diuretic, which can deplete potassium levels.

B. Magnesium 1.4 mEq/L (1.3-2.1): Although the magnesium level is on the lower end of normal, it is not a critical value, and the primary concern here is the potassium level.

C. Calcium 10 mg/dL (9.9-10.5): This is a normal calcium level, so there is no need to notify the provider based on this result.

D. Sodium 136 mEq/L (136-145): This is a normal sodium level, so it would not warrant notifying the provider. The critical concern is the hypokalemia.

Correct Answer is C

Explanation

A. Crackles: Crackles in the lungs are a sign of left-sided heart failure, as fluid backs up into the pulmonary system.

B. Productive cough: A productive cough is also more commonly associated with left-sided heart failure, as it can result from fluid accumulation in the lungs.

C. Hepatomegaly: Hepatomegaly is a sign of right-sided heart failure, as blood backs up into the systemic circulation, leading to congestion in the liver.

D. Dizziness: Dizziness may occur in left-sided heart failure due to decreased cardiac output, but it is not a typical finding in right-sided heart failure.

Correct Answer is ["7.5"]

Explanation

Desired dose: 20 mEq

Available concentration: 40 mEq/15 mL

Formula:

mLtoadminister = (Desireddose÷ Availableconcentration) × 15mL

= (20mEq ÷ 40mEq) × 15

= 7.5mL

Therefore, the nurse should administer 7.5 mL of potassium chloride.
