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.
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. Metabolic alkalosis occurs because vomiting causes loss of gastric hydrochloric acid (HCl), reducing hydrogen ions in the body and increasing blood pH. This is the most common acid-base imbalance associated with prolonged vomiting.
B. Respiratory alkalosis results from excessive loss of CO₂ due to hyperventilation, unrelated to vomiting.
C. Respiratory acidosis results from hypoventilation causing CO₂ retention; vomiting does not cause this.
D. Metabolic acidosis occurs when there is a loss of bicarbonate or accumulation of acids, such as in diarrhea or ketoacidosis, not typically from vomiting.
Correct Answer is D
Explanation
Rationale:
A. Hemoglobin is important for evaluating oxygen-carrying capacity and detecting anemia, but spironolactone does not directly affect hemoglobin levels. This value is not a priority for monitoring the effects of spironolactone.
B. Cholesterol levels are relevant for assessing cardiovascular risk, but spironolactone does not significantly impact lipid profiles. Therefore, total cholesterol is not the most important lab to monitor for this medication.
C. TSH is used to evaluate thyroid function. Spironolactone does not influence thyroid hormones or TSH levels, so this value is unrelated to the medication’s expected effects or complications.
D. Spironolactone is a potassium-sparing diuretic. It works by antagonizing aldosterone in the distal tubule, leading to retention of potassium. This can result in hyperkalemia, especially in older adults or those with renal impairment. Monitoring serum potassium is essential to prevent life-threatening arrhythmias and other complications.
