A nurse is obtaining a urine specimen for culture and sensitivity via a straight catheterization. Which of the following actions should the nurse take?

When reinforcing teaching with a client who has a duodenal ulcer and a new prescription for cimetidine, the nurse should include the following instructions:

"Avoid taking the medication at bedtime.": Cimetidine is most effective when taken during waking hours to help control gastric acid secretion. Taking it at bedtime may not provide optimal therapeutic benefits.

"You will need to continue taking this medication for up to 6 weeks.": Cimetidine is often prescribed for the treatment of duodenal ulcers and may require several weeks of continuous use to promote healing. It is important for the client to understand the duration of treatment and the need for adherence to the prescribed regimen.

The following statements are incorrect or not applicable:

"Drinking grapefruit juice while taking cimetidine can lead to toxicity.": Cimetidine does not have a known interaction with grapefruit juice. However, it is always important to consult the healthcare provider or pharmacist about potential drug interactions, including those related to specific foods or beverages.

"Take an antacid 30 minutes prior to taking cimetidine to minimize stomach upset.": Cimetidine is an H2 receptor antagonist that works by reducing stomach acid production. It is not necessary to take an antacid prior to taking cimetidine to minimize stomach upset. However, if the client experiences stomach upset or discomfort, they should consult their healthcare provider for further guidance on managing these symptoms.

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.
