Question 1:
A nurse is preparing to administer morphine 4 mg IV bolus. Available is
morphine injection 10 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.)
Explanation
Correct Answer: 0.4 ml
- To calculate the amount of morphine injection needed, use the formula: D/H x V = A,
where D is the desired dose, H is the dose on hand, V is the volume on hand, and A is
the amount to administer.
- Plug in the values from the question: 4 mg / 10 mg x 1 ml = 0.4 ml
- Round the answer to the nearest tenth: 0.4 ml
- The nurse should administer 0.4 ml of morphine injection.

Question 2:
A nurse is preparing to administer dobutamine 10 mcg/kg/min by continuous IV
infusion to a client who weighs 110 lb. Available is dobutamine 250 mg in 250
mL dextrose 5% in water. 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.)
Explanation
Correct Answer: 30 mL\/hour
To solve this problem, the nurse needs to convert the client's weight from pounds to
kilograms, and then use the formula:
mL/hr = (mcg/kg/min x kg x 60 min) / (mg/mL x 1000 mcg/mg)
The client's weight in kilograms is:
110 lb / 2.2 lb/kg = 50 kg
The concentration of dobutamine in mg/mL is:
250 mg / 250 mL = 1 mg/mL
Plugging these values into the formula, we get:
mL/hr = (10 mcg/kg/min x 50 kg x 60 min) / (1 mg/mL x 1000 mcg/mg) mL/hr =
(30,000 mcg/min) / (1000 mcg/mg)
mL/hr = 30 mg/min
mL/hr = 30 mL/hr
Therefore, the nurse should set the IV pump to deliver 30 mL/hr.

Question 3:
A nurse is preparing to administer foscarnet 60 mg/kg via intermittent IV bolus
to a client who weighs 126 lb. Available is foscarnet 6,000 mg in 500 mL of 0.9%
sodium chloride solution. 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.)
Explanation
Correct Answer: 286 mL
To solve this problem, the nurse needs to convert the client's weight from
pounds to kilograms, and then use the formula:
mL = (mg/kg x kg) / (mg/mL)
The client's weight in kilograms is:
126 lb / 2.2 lb/kg = 57.27 kg
The concentration of foscarnet in mg/mL is:
6,000 mg / 500 mL = 12 mg/mL
Plugging these values into the formula, we get:
mL = (60 mg/kg x 57.27 kg) / (12 mg/mL)
mL = (3,436.2 mg) / (12 mg/mL)
mL = 286.35 mL
Therefore, the nurse should administer 286 mL of foscarnet.

Question 2:
A nurse is preparing to administer dobutamine 10 mcg/kg/min by continuous IV
infusion to a client who weighs 110 lb. Available is dobutamine 250 mg in 250
mL dextrose 5% in water. 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.)
Explanation
Correct Answer: 30 mL\/hour
To solve this problem, the nurse needs to convert the client's weight from pounds to
kilograms, and then use the formula:
mL/hr = (mcg/kg/min x kg x 60 min) / (mg/mL x 1000 mcg/mg)
The client's weight in kilograms is:
110 lb / 2.2 lb/kg = 50 kg
The concentration of dobutamine in mg/mL is:
250 mg / 250 mL = 1 mg/mL
Plugging these values into the formula, we get:
mL/hr = (10 mcg/kg/min x 50 kg x 60 min) / (1 mg/mL x 1000 mcg/mg) mL/hr =
(30,000 mcg/min) / (1000 mcg/mg)
mL/hr = 30 mg/min
mL/hr = 30 mL/hr
Therefore, the nurse should set the IV pump to deliver 30 mL/hr.

A nurse is preparing to administer foscarnet 60 mg/kg via intermittent IV bolus
to a client who weighs 126 lb. Available is foscarnet 6,000 mg in 500 mL of 0.9%
sodium chloride solution. How many ml should the nurse administer? (Round

Explanation
Correct Answer: 286 mL
To solve this problem, the nurse needs to convert the client's weight from
pounds to kilograms, and then use the formula:
mL = (mg/kg x kg) / (mg/mL)
The client's weight in kilograms is:
126 lb / 2.2 lb/kg = 57.27 kg
The concentration of foscarnet in mg/mL is:
6,000 mg / 500 mL = 12 mg/mL
Plugging these values into the formula, we get:
mL = (60 mg/kg x 57.27 kg) / (12 mg/mL)
mL = (3,436.2 mg) / (12 mg/mL)
mL = 286.35 mL
Therefore, the nurse should administer 286 mL of foscarnet.
