Question 1 of 5
The nurse calculates that 8 ml of cefazolin is to be drawn from a vial after reconstitution. The instructions state that the medication is to be further diluted in 50 mls of NSS for IV administration and to run over 30 minutes. At what rate will the nurse set to infusion pump to deliver the medication?
Correct Answer: A
Rationale: The correct answer is A: 116 mL/hr.
To calculate the infusion rate, we first convert the total volume to be infused (58 mL) into hours (30 minutes = 0.5 hours).
Then, we divide the total volume by the total time to get the infusion rate in mL/hr.
Therefore, 58 mL / 0.5 hr = 116 mL/hr. This rate ensures the medication is delivered over the specified 30-minute duration.
Incorrect choices:
B, C, D, E, F, G: These choices are incorrect as they do not provide the calculated infusion rate based on the total volume and time specified in the question. Without the correct calculation, these choices do not accurately reflect the rate at which the medication should be administered.
