A nurse is preparing to administer gentamicin to a child who weighs 44 lb. The provider prescribes 6 mg/kg/day IV to be administered in three equal doses. Available is gentamicin 40 mg/mL. How many mL should the nurse administer with each dose?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

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.

Choice A rationale:

Hoarseness of voice can be a symptom of an allergic reaction, indicating swelling and inflammation in the throat. If the client’s voice is no longer hoarse after taking diphenhydramine, it suggests that the medication has been effective in reducing this symptom.

Choice B rationale:

Diphenhydramine is an antihistamine and can often cause drowsiness as a side effect. Therefore, feeling more alert would not typically indicate that the medication has been effective.

Choice C rationale:

While headaches can sometimes be associated with allergic reactions, they are not a primary symptom that diphenhydramine targets. Therefore, absence of a headache does not necessarily indicate effectiveness of the medication.

Choice D rationale:

Increased appetite is not typically associated with the effectiveness of diphenhydramine in treating allergic reactions.
