NurseDive Free Nursing Practice Question
A nurse is preparing to administer dextrose 5% in lactated Ringer's 2 L IV to infuse over 12 hr. The drop factor on the manual IV tubing is 20 gtt/mL. The nurse should set the IV flow rate to deliver how many gtt/min? (Round the answer to the nearest whole number.
Use a leading zero if it applies.
Do not use a trailing zero.). gtt/min.

Full Explanation
Step 1 is to calculate the total volume to be infused in minutes. This is done by multiplying the total volume (2000 mL) by the drop factor (20 gtt/mL), and then dividing by the total time (12 hr × 60 min/hr). So, (2000 mL × 20 gtt/mL) ÷ (12 hr × 60 min/hr) = 55.56 gtt/min, which rounds to 56 gtt/min.

A nurse is preparing to administer acetaminophen 15 mg/kg via intermittent IV bolus to a client who weighs 99 lb. The amount available is acetaminophen 1,000 mg/100 mL. How many mL should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Full Explanation
Step 1 is to convert the client’s weight from pounds to kilograms, as the dosage is prescribed in mg/kg. Given that 1 kg = 2.2 lb, we calculate:
99 lb ÷ 2.2 = 45 kg
Rounding to the nearest whole number, the client’s weight is 45 kg.
Step 2 is to determine the total dosage of acetaminophen required. The prescribed dosage is 15 mg/kg, so we calculate:
15 mg/kg × 45 kg = 675 mg
Step 3 is to determine the volume to administer. The available concentration of acetaminophen is 1,000 mg/100 mL, which simplifies to 10 mg/mL. So, we divide:
675 mg ÷ 10 mg/mL = 67.5 mL
Rounding to the nearest whole number, the correct amount to administer is 68 mL.
A nurse is preparing to administer amikacin 5 mg/kg via intermittent IV bolus to a client who weighs 219 lb. Available is amikacin 10 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Full Explanation
Step 1 is to convert the client’s weight from pounds to kilograms, since the dosage is prescribed in mg/kg. Given that 1 kg = 2.2 lb, we calculate:
219 lb ÷ 2.2 = 99.5 kg
Rounding to the nearest whole number, the client’s weight is 100 kg.
Step 2 is to determine the total dosage of amikacin required. The prescribed dosage is 5 mg/kg, so we calculate:
5 mg/kg × 100 kg = 500 mg
Step 3 is to determine the volume to administer. The available concentration of amikacin is 10 mg/mL, so we divide:
500 mg ÷ 10 mg/mL = 50 mL
Thus, the correct amount to administer is 50 mL.
A nurse is preparing to administer enoxaparin 40 mg subcutaneous for prevention of deep vein thrombosis.
Available is enoxaparin 100 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth.
Use a leading zero if it applies.
Do not use a trailing zero.). mL. .
Full Explanation
The prescribed dosage of enoxaparin is 40 mg. The available medication is in a concentration of 100 mg/mL. So, the volume to administer is 40 mg ÷ 100 mg/mL = 0.4 mL. Rounding to the nearest tenth, the nurse should administer 0.4 mL.
So, the correct answer is 0.4 mL.
