A nurse is reviewing the medication history of a client who reports urinary retention.
The nurse should recognize that which of the following medications can cause this adverse reaction?

Choice A rationale:

Renal excretion time slows for medication. As people age, kidney function gradually decreases, which slows the excretion of medications. This can lead to increased levels of the drug in the body, which can increase the risk of side effects.

Choice B rationale:

Hepatic enzymes do not process medications more rapidly in older adults. In fact, liver function also decreases with age, which can slow the metabolism of medications.

Choice C rationale:

Brain receptors do not become less sensitive to medications in older adults. The sensitivity of brain receptors to medications can vary widely and is not necessarily related to age.

Choice D rationale:

Gastric emptying rate does not increase with age. On the contrary, it often slows down, which can affect the absorption of some medications.

Choice A rationale:

Oxycodone overdose typically results in constricted (not dilated) pupils due to its action on the central nervous system.

Choice B rationale:

Oxycodone overdose can cause respiratory depression, leading to slow and shallow breathing (bradypnea), not rapid breathing (tachypnea)

Choice C rationale:

Oxycodone does not typically cause tachycardia. It can cause bradycardia due to its action on the central nervous system.

Choice D rationale:

Sedation is a common effect of oxycodone and can be more pronounced in cases of overdose due to the drug’s depressant effect on the central nervous system.
