A nurse is preparing to administer lactated Ringer's 250 mL IV to infuse over 15 min.
The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number.
Use a leading zero if it applies.
Do not use a trailing zero.). mL/hr.
The Correct Answer is ["1000"]
Step 1 is to calculate the total volume to be infused in mL/hr. This is done by dividing the total volume (250 mL) by the time in hours (15 min ÷ 60 min/hr). So, 250 mL ÷ (15 min ÷ 60 min/hr) = 1000 mL/hr.
So, the correct answer is 1000 mL/hr.

Correct Answer is ["0.8"]
Explanation
Step 1 is to convert the client’s weight from pounds to kilograms. Given that 1 kg = 2.2 lb, we calculate:
183 lb ÷ 2.2 = 83.18 kg
Rounding to the nearest hundredth, the client’s weight is 83.18 kg.
Step 2 is to calculate the total amount of medication needed. The prescribed dosage is 0.1 mg/kg, so we calculate:
0.1 mg/kg × 83.18 kg = 8.32 mg
Rounding to the nearest hundredth, the total medication required is 8.32 mg.
Step 3 is to determine the volume to administer. The available concentration of furosemide is 10 mg/mL, so we divide:
8.32 mg ÷ 10 mg/mL = 0.832 mL
Rounding to the nearest tenth, the correct amount to administer is 0.8 mL.
Correct Answer is D
Explanation
Choice A rationale:
Meloxicam 15 mg PO daily is a standard dose for treating osteoarthritis and rheumatoid arthritis.
Choice B rationale:
Regular insulin 8 units subcutaneous before meals is a typical dose for managing blood glucose levels in diabetes.
Choice C rationale:
Docusate sodium 200 mg PO at bedtime is a common dose for preventing constipation.
Choice D rationale:
Fentanyl 25 mcg/hr transdermal patch is a potent opioid, and the dose should be carefully monitored. If the client has not been on opioid therapy, this dose might be too high.
