A medication is to infuse at 15 mcg/min. The solution available is 25 mg/100 mL. The nurse should set the IV pump to deliver how many mL/hr? (Round to the nearest whole number & fill in the blank with the numerical value only)
The Correct Answer is ["4"]
Desired dose rate = 15 mcg/min
- Convert the desired dose rate to mg/hr:
1000 mcg = 1 mg and 60 minutes = 1 hour.
Desired dose rate (mg/hr) = 15 mcg/min × (1 mg / 1000 mcg) × (60 min / 1 hr)
= (15 × 60) / 1000 mg/hr
= 900 / 1000 mg/hr
= 0.9 mg/hr
Available concentration = 25 mg / 100 mL
- Calculate the flow rate in mL/hr:
Flow rate (mL/hr) = Desired dose rate (mg/hr) / Concentration (mg/mL)
= 0.9 mg/hr / (25 mg / 100 mL)
= 0.9 mg/hr / 0.25 mg/mL
= 0.9 / 0.25 mL/hr
= 3.6 mL/hr
Round to the nearest whole number:
= 4 mL/hr

Correct Answer is ["150"]
Explanation
Total volume to be infused = 1200 mL
Total infusion time = 8 hours
- Calculate the flow rate in mL per hour (mL/hr):
Flow rate (mL/hr) = Total volume (mL) / Total infusion time (hours)
= 1200 mL / 8 hours
= 150 mL/hr
Correct Answer is A
Explanation
A. Tablets: The drug label clearly states "Zoloft (sertraline hydrochloride) tablets," indicating that this formulation is in tablet form. It also mentions "30 Tablets" directly below the dosage strength, confirming the correct formulation.
B. Lozenge: Lozenges are designed to dissolve slowly in the mouth for local effect and are not typically used for systemic antidepressants like sertraline. This formulation is not indicated on the label.
C. Elixir: An elixir is a liquid form of medication containing alcohol, and although sertraline can be made in liquid form, this label specifically refers to tablets, not a liquid preparation.
D. Capsules: Capsules contain medication enclosed in a gelatin shell, often used for extended-release purposes. The label does not mention capsules and explicitly says "tablets," making this option incorrect.
