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?
Donepezil.
Scopolamine.
Metoprolol.
Acetaminophen.
The Correct Answer is B
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.

Correct Answer is C
Explanation
Choice A rationale:
Pinching the tube while connecting the syringe to it could potentially damage the tube and does not aid in medication administration.
Choice B rationale:
Elevating the head of the client’s bed to only 10° may increase the risk of aspiration. The head of the bed should be elevated to at least 30° during medication administration and for at least an hour afterward.
Choice C rationale:
Flushing the tube with normal saline following medication administration helps ensure that all medication has been administered and helps maintain tube patency.
Choice D rationale:
Combining crushed medications together in a single syringe can lead to drug interactions and can also increase the risk of tube clogging. Each medication should be administered separately.
Correct Answer is B
Explanation
Choice A rationale:
A urine output of 600 mL in 8 hours is within the normal range. The average urine output for adults is about 1 to 2 liters per day.
Choice B rationale:
Clonidine is an antihypertensive medication. If the client’s blood pressure is already low (88/50 mm Hg), administering clonidine could further lower the blood pressure and cause hypotension.
Choice C rationale:
A heart rate of 110/min is slightly high, but it’s not a direct indication to withhold clonidine. Clonidine can actually help lower an elevated heart rate by reducing the levels of certain chemicals in your blood.
Choice D rationale:
A blood glucose level of 70 mg/dL is at the lower end of the normal range (70-100 mg/dL) However, clonidine does not directly affect blood glucose levels, so this would not be a reason to withhold the medication.
