A nurse is caring for a client who has been taking epoetin alfa for 3 months.
Which of the following laboratory tests should the nurse monitor to determine the effectiveness of the medication?

To calculate the dose of somatropin to be administered per dose, we first need to convert the child's weight from pounds to kilograms. We can do this using the following conversion factor:

1 kg = 2.2 lbs

Therefore, the child's weight in kilograms is:

weight_kg = 66 lbs / 2.2 lbs/kg = 30 kg

Next, we can calculate the total dose of somatropin to be administered per week using the following formula:

total_dose = weight_kg * 0.24 mg/kg/week

This gives us a total dose of:

total_dose = 30 kg * 0.24 mg/kg/week = 7.2 mg/week

Finally, we can calculate the dose of somatropin to be administered per dose by dividing the total dose by the number of daily doses:

dose_per_dose = total_dose / 6 doses/day = 1.2 mg/dose

Therefore, the nurse should administer 1.2 mg of somatropin per dose.

Answer: 1.2 mg of somatropin per dose.

Choice A rationale:

Donepezil is a medication used to treat symptoms of Alzheimer’s disease and does not typically cause urinary retention.

Choice B rationale:

Scopolamine, an anticholinergic drug, can cause urinary retention. Anticholinergic drugs block the action of acetylcholine, a neurotransmitter that helps to contract the bladder muscles and relax the urinary sphincters to allow urination.

Choice C rationale:

Metoprolol is a beta-blocker used to treat high blood pressure and heart problems. It does not typically cause urinary retention.

Choice D rationale:

Acetaminophen is a common over-the-counter pain reliever and does not typically cause urinary retention.
