A nurse is reviewing the medication history of a client. The nurse should identify that which of the following medications places the client at risk for hypokalemia?

Metoclopramide is a medication commonly used to treat gastrointestinal disorders such as gastroesophageal reflux disease (GERD). While it is generally well-tolerated, it can have some adverse effects. Sedation is one of the common side effects of metoclopramide. It can cause drowsiness, dizziness, and a feeling of tiredness in some individuals. Therefore, the nurse should monitor the client for any signs of sedation or excessive drowsiness, especially when the client starts taking the medication or when the dose is increased.

Hypertension: Metoclopramide is not known to cause hypertension (high blood pressure) as a common side effect. In fact, it may have a mild hypotensive (blood pressure-lowering) effect in some individuals.

Urinary retention: Metoclopramide does not typically cause urinary retention. Instead, it can enhance gastrointestinal motility and increase the frequency of bowel movements.

Blurred vision: While visual disturbances are rare adverse effects of metoclopramide, blurred vision is not a commonly reported side effect. However, other visual disturbances like oculogyric crisis (involuntary rolling back of the eyes) have been reported in rare cases. Nevertheless, monitoring for blurred vision specifically is not a priority when administering metoclopramide.

When collecting a urine specimen via straight catheterization, it is important to use a sterile specimen container to maintain the integrity of the sample and prevent contamination. Using a non-sterile container can introduce bacteria and affect the accuracy of the culture and sensitivity results.

The other options mentioned are incorrect:

Using sterile water to inflate the balloon: This action is relevant when inflating the balloon of an indwelling urinary catheter, but in a straight catheterization, there is no balloon involved.

Instructing the client to clean from front to back with an antiseptic solution: This instruction is appropriate for cleaning the urethral meatus before inserting an indwelling urinary catheter, but in a straight catheterization, the nurse performs the procedure using sterile technique and does not require the client to clean themselves.

Collecting urine from the catheter's port: In a straight catheterization, the nurse collects urine directly from the catheter tube using a sterile syringe or collection container, rather than from a separate port.
