A nurse is preparing to administer 20mEq of potassium chloride IV, diluted in 500mL of 0.9% saline solution. The nurse plans to infuse the solution via a peripheral IV access, using tubing with a drop factor of 30gtts/mL, over 2 hours. How many mL/hr should the nurse program the IV pump to deliver? Record your answer as a whole number.

Answer and Explanation

The Correct Answer is ["250"]

Rationale:

To calculate the IV pump rate in mL/hr, use the formula:

mL/hr = Total volume (mL) ÷ Total time (hr)

Total volume = 500 mL
Total time = 2 hours

mL/hr = 500 ÷ 2 = 250

Correct Answer is A

Explanation

Rationale:

A. Hold the medication and inform the provider of the client's potassium level: A potassium level of 5.8 mEq/L indicates hyperkalemia (normal range is 3.5–5.0 mEq/L). Administering potassium chloride in this situation could worsen the hyperkalemia and lead to serious cardiac complications. The provider should be notified immediately.

B. Obtain an order to increase the dosage of the medication: This would be unsafe and inappropriate since the potassium level is already elevated.

C. Hold the medication until the client has his evening meal: Delaying the dose does not address the issue. The problem is the elevated potassium, not the timing.

D. Give the medication as prescribed: Administering potassium in the presence of hyperkalemia is dangerous and could result in life-threatening arrhythmias.

A. 4.9 mEq/L B. 5.5 mEq/L C. 6.2 mEq/L D. 5.8 meq/L

Correct Answer is A

Explanation

Rationale:
A. A potassium level of 4.9 mEq/L is within the normal reference range (typically 3.5–5.0 mEq/L), indicating that the hyperkalemia has been successfully corrected.
B. A potassium level of 5.5 mEq/L is still above normal and does not suggest full effectiveness of the treatment.
C. A potassium level of 6.2 mEq/L remains critically high and indicates that the medication was not effective.
D. A potassium level of 5.8 mEq/L is still elevated and may continue to pose cardiac risks, suggesting partial or no effectiveness.
