A nurse is preparing to administer cimetidine 300 mg IV over 15 min to a client. Available is cimetidine 300 mg/100 mL of 0.9% sodium chloride. 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. Done use a trailing zero.)

Answer and Explanation

The Correct Answer is ["400"]

Step 1: Determine the Total Volume Needed

Supplied concentration: 300 mg/100 mL
Prescribed dose: 300 mg
Total volume needed = 100 mL

Step 2: Convert Time to Hours

Prescribed infusion time = 15 minutes
15 minutes ÷ 60 minutes/hour = 0.25 hours

Step 3: Calculate the Infusion Rate (mL/hr)

Infusion rate = Total volume (mL) ÷ Time (hours)
Infusion rate = 100 mL ÷ 0.25 hours
Infusion rate = 400 mL/hr

The nurse should set the IV pump to deliver cimetidine at 400 mL/hr (rounded to the nearest whole number).

Correct Answer is B

Explanation

A. "You should take this medication on an empty stomach:"
Bumetanide can be taken with or without food. It is not necessary to take it on an empty stomach.
B. "You should monitor for hearing difficulties:"
This is the correct answer. Loop diuretics, including bumetanide, are associated with ototoxicity, which can lead to hearing difficulties or hearing loss. Clients should be instructed to report any changes in hearing.
C. "You should decrease your intake of foods high in potassium:"
Bumetanide can cause potassium loss, but instructing the client to decrease potassium intake may not be appropriate without knowing the client's specific potassium levels. Monitoring potassium levels and adjusting the diet or prescribing supplements as needed would be a more individualized approach.
D. "You should take the medication at bedtime:"
Bumetanide is often prescribed in the morning to avoid disrupting sleep with increased urination during the night. Taking it at bedtime is not a typical recommendation.

Correct Answer is ["20"]

Explanation

Step 1: Convert Weight to Kilograms

1 lb = 0.4536 kg
132 lb × 0.4536 kg/lb = 59.87 kg

Step 2: Calculate Total Dose of Acyclovir

Prescribed dose = 10 mg/kg
Total dose = 59.87 kg × 10 mg/kg = 598.75 mg

Step 3: Determine the Volume of Injectable Solution

Acyclovir IV concentration = 30 mg/mL
Volume = 598.75 mg ÷ 30 mg/mL = 19.96 mL

The nurse should administer 20 mL (rounded to the nearest whole number) of acyclovir IV injectable solution.
