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)
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 ["31"]
Explanation
Desired volume: 1 L = 1,000 mL
Infusion time: 8 hours = 480 minutes
Drop factor: 15 gtts/mL
Formula: (Volume(mL) ÷ Time(min)) × Dropfactor(gtts/mL)
= (1000 ÷ 480) × 15
= 31.25
Rounded to the nearest whole number: 31 gtt/min
Correct Answer is ["22.5"]
Explanation
Ordered dose: 30 mEq
Available concentration: 20 mEq/15 mL
Calculation:
To find the volume needed: (30 mEq ÷ 20 mEq) ×15 mL = 22.5 mL
Therefore, the nurse should administer 22.5 mL of potassium chloride.
