Question 1 of 5
Calculate the flow rate in mL/hr. and Units/hr. (Equipment used is programmable in whole mL/hr and Show all work) Order: 100 mL 0.45% NS in 45 min by infusion pump. Calculate rate in ml/hr
Correct Answer: A
Rationale:
To calculate the flow rate in mL/hr, we first convert 45 min to hours by dividing by 60 (45 min / 60 min/hr = 0.75 hr).
Then, we divide the total volume to be infused (100 mL) by the time in hours (0.75 hr) to get the flow rate in mL/hr: 100 mL / 0.75 hr = 133 mL/hr.
Therefore, the correct answer is A. Option B is incorrect as it is one-tenth of the correct value. Option C is incorrect as it is close but not the exact calculation. Option D is incorrect as it is also one-tenth of the correct value.
