A nurse is preparing to administer enoxaparin 1 mg/kg subcutaneous to a client who weighs 165 lb. Available is enoxaparin 30 mg/0.3 mL. How many ml should the nurse administer per dose?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.8"]
To calculate the dose of enoxaparin, we need to convert the client's weight from pounds to kilograms.
1 kg=2.2 Ib
? kg= 165Ib
=165/2.2
=75kg
Desired med is 1mg/kg
total dose to administer= 75mg
Available formulation is 30mg/0.3ml
total volume to administer
30mg=0.3ml
75mg= 75*0.3/30
=0.75ml
Rounded off to the nearest tenth = 0.8ml

Correct Answer is ["3.5"]
Explanation
-
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 ["0.25"]
Explanation
To convert micrograms to milligrams, divide by 1000: 250 mcg / 1000 = 0.25 mg. Round to the nearest hundredth: 0.25 mg. Therefore, the nurse should administer 0.25 mg of filgrastim.
