Fosamax (alendronate sodium) 60 mg by mouth is ordered. Fosamax 70 mg/75 mL is available. How many milliliters should the nurse administer to the patient?
Round to the nearest whole number.
56 mL
64 mL
65 mL
88 mL
The Correct Answer is B
Step 1: Determine the dosage ratio. 60 mg (ordered) ÷ 70 mg (available) = 0.8571 (rounded to 4 decimal places)
Step 2: Calculate the volume to administer. 0.8571 × 75 mL (available) = 64.2857 mL (rounded to 4 decimal places)
Step 3: Round to the nearest whole number. 64.2857 mL rounds to 64 mL
So, the nurse should administer 64 mL to the patient.
The correct answer is B. 64 mL.

Correct Answer is C
Explanation
To calculate the dose of ondansetron for this client, we need to use the client's weight and the prescribed dose of 0.34 mg/kg.
The formula to calculate the dose is:
Dose (in mg) = Weight (in kg) x Dose (in mg/kg) So, for this client:
Dose (in mg) = 70 kg x 0.34 mg/kg
Dose (in mg) = 23.8 mg (rounded to one decimal place)
Therefore, the client should receive a dose of 23.8 mg of ondansetron, 30 minutes prior to chemotherapy.
Correct Answer is A
Explanation
To calculate the total amount of heparin, we need to multiply the infusion rate by the time and then by the concentration of heparin in the IV bag. From 9:00 a.m. to 11:00 a.m., the infusion rate was 12 mL/hr, so the amount of heparin infused in this period was 12 mL/hr x 2 hours x 100 units/mL = 2400 units.
From 11:00 a.m. to 2:00 p.m., the infusion rate was 10 mL/hr, so the amount of heparin infused in this period was 10 mL/hr x 3 hours x 100 units/mL = 3000 units. The total amount of heparin infused from 9:00 a.m. to 2:00 p.m. was 2400 units + 3000 units = 5400 units.
