A nurse is preparing to administer dextrose 5% in water 1,000 mL IV to infuse over 6 hr. 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.)
The Correct Answer is ["167"]
To calculate the infusion rate in mL/hr for dextrose 5% in water 1,000 mL over 6 hours, you can use the following formula:
Infusion Rate (mL/hr) = Total Volume (mL) / Total Time (hr)
Infusion Rate = 1,000 mL / 6 hr ≈ 166.67 mL/hr
Rounded to the nearest whole number, the nurse should set the IV pump to deliver approximately 167 mL/hr.

Explanation
To calculate how many tablets of pyrazinamide the nurse should administer, you can use the following steps:
Convert the client's weight from pounds (lb) to kilograms (kg):
Client's weight in kg = Client's weight in lb / 2.2 Client's weight in kg = 165 lb / 2.2 ≈ 75 kg
Determine the total dosage required based on the client's weight:
Total dosage = Client's weight in kg × Dosage (mg/kg) Total dosage = 75 kg × 20 mg/kg = 1500 mg
Determine the number of tablets needed:
Number of tablets = Total dosage / Tablet strength Number of tablets = 1500 mg / 500 mg/tablet = 3 tablets
The nurse should administer 3 tablets of pyrazinamide
Correct Answer is ["1.5"]
Explanation
First, we need to calculate the amount of cefazolin 500 mg in milligrams per milliliter (mg/mL) using the information provided:
Cefazolin concentration after reconstitution = 330 mg/mL Amount of cefazolin needed per dose = 500 mg
Now we can calculate the volume (mL) required for the dose:
Volume (mL) = Amount of cefazolin needed per dose / Cefazolin concentration after reconstitution
Volume (mL) = 500 mg / 330 mg/mL ≈ 1.52 mL
Rounded to the nearest tenth, the nurse should administer approximately 1.5 mL of cefazolin per dose.
