The Correct Answer is ["1.5"]
To calculate the number of tablets to administer, you can use the following calculation:
Number of tablets = Desired dose (mg) / Tablet strength (mg per tablet)
Number of tablets = 15 mg / 10 mg per tablet
Number of tablets = 1.5 tablets

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.
Correct Answer is ["68"]
Explanation
To calculate the mL of acetaminophen to administer, follow these 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 = 99 lb / 2.2 ≈ 45 kg
Determine the total dosage required based on the client's weight:
Total dosage = Client's weight in kg × Dosage (mg/kg) Total dosage = 45 kg × 15 mg/kg = 675 mg
Determine the mL to administer based on the available concentration:
Concentration (mg/mL) = 1,000 mg / 100 mL = 10 mg/mL
Calculate the mL to administer:
mL to administer = Total dosage (mg) / Concentration (mg/mL) mL to administer = 675 mg / 10 mg/mL = 67.5 mL
Round the answer to the nearest whole number:
The nurse should administer 68 mL of acetaminophen
