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 ["20"]
Explanation
To calculate the volume of medication to administer, use the formula: (desired dose / available dose) x available volume. Plug in the values: (25 mg / 6.25 mg) x 5 mL = 20 mL. Round to the nearest whole number: 20 mL.
Correct Answer is ["30"]
Explanation
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.
