2024 PN NCLEX Questions Nursing Practice Question
A 50 milliliter (ml) bolus of normal saline fluid is ordered by the physician. The physician wants it to infuse in 30 minutes. The nurse should set the pump rate at:
Correct Answer: A
Rationale: To determine the correct pump rate for a 50 ml bolus to infuse over 30 minutes, the calculation involves converting the infusion time into hours. Since 30 minutes equals 0.5 hours, the required rate is 50 ml divided by 0.5 hours, resulting in 100 ml per hour.
Option B (60 ml per hour for one-half hour) is incorrect as it would only deliver 30 ml in 30 minutes. Option C (120 ml per hour for one hour) is incorrect because it would infuse 120 ml, exceeding the ordered bolus. Option D (50 ml per hour for one hour) is also incorrect, as it would take one hour to deliver the 50 ml, rather than the required 30 minutes.
