A nurse is preparing to administer diltiazem IV 0.25 mg/kg IV bolus given over 2 min to a client who has atrial fibrillation and weighs 154 lb. Available is diltiazem IV injection 25 mg/5 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.)
The Correct Answer is ["3.5"]
-
Convert the client's weight from pounds to kilograms:
- 154 lb ÷ 2.2 lb/kg = 70 kg
-
Calculate the total dose required:
- 0.25 mg/kg × 70 kg = 17.5 mg
-
Determine the volume to administer:
- Given concentration: 5 mg/mL
- 17.5 mg ÷ 5 mg/mL = 3.5 mL
-
Rounding to the nearest tenth:
- The answer remains 3.5 mL
So the nurse should administer 3.5 mL of diltiazem IV injection.
which is 17.5 mg / 5 mg/mL = 3.5 mL. Rounding to the nearest tenth, the nurse should administer 3.5 mL of diltiazem IV injection.

Correct Answer is ["6.5"]
Explanation
To answer this question, we need to perform some calculations. First, we need to convert the client's weight from pounds to kilograms. We can do this by dividing 143 by 2.2, which gives us 65 kg. Next, we need to multiply the dose of cyclosporine by the client's weight to get the total amount of medication needed. We can do this by multiplying 5 mg/kg by 65 kg, which gives us 325 mg. Finally, we need to divide the total amount of medication by the concentration of the injection to get the volume to administer. We can do this by dividing 325 mg by 50 mg/mL, which gives us 6.5 mL. Therefore, the nurse should administer 6.5 mL of cyclosporine injection to the client.
Correct Answer is ["67"]
Explanation
To solve this problem, the nurse needs to use the formula:
gtt/min = (Volume in mL x Drop factor in gtt/mL) / Time in min
Plugging in the given values, we get:
gtt/min = (100 x 10) / 15
gtt/min = 66.67
Rounding to the nearest whole number, we get:
gtt/min = 67
Therefore, the nurse should set the manual IV infusion to deliver 67gtt/min.
