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 C

Explanation

Rationale:
A. Metabolic alkalosis is related to an excess of bicarbonate or loss of acid, not CO₂ retention.
B. Metabolic acidosis is caused by the accumulation of acids (like in renal failure or DKA), not respiratory dysfunction.
C. Respiratory acidosis occurs when the lungs fail to excrete enough CO₂, leading to CO₂ retention and a decrease in blood pH. This is commonly seen in conditions like COPD, respiratory depression, or airway obstruction.
D. Respiratory alkalosis results from excessive elimination of CO₂, such as in hyperventilation, which is the opposite of what is described.
