A client with gastroenteritis is experiencing severe dehydration. The nurse should anticipate the need for which intervention?

Choice A rationale:

Vaginal itching is a common symptom of vulvovaginitis but not a potential adverse effect of antibiotics. It is more indicative of the condition itself rather than a medication side effect.

Choice B rationale:

A fishy odor is characteristic of bacterial vaginosis (BV), not a common adverse effect of antibiotics. BV is caused by an imbalance in vaginal flora and is not directly related to antibiotic therapy.

Choice C rationale:

Increased vaginal discharge is a potential adverse effect of antibiotics. Antibiotics can disrupt the normal vaginal flora, leading to an overgrowth of yeast or other pathogens, which may result in increased discharge.

Choice D rationale:

Photosensitivity is unrelated to antibiotics or vulvovaginitis. It refers to an increased sensitivity to sunlight or artificial light and is not a relevant consideration in this context.

Choice A rationale:

Assessing blood glucose levels is not directly related to ondansetron administration for vomiting. Ondansetron does not typically affect blood glucose levels.

Choice B rationale:

Obtaining a stool sample for culture and microscopy is important for diagnosing the cause of gastroenteritis, but it is not a necessary step before administering ondansetron.

Choice C rationale:

Monitoring urinary output is not directly associated with the administration of ondansetron. It's important for assessing hydration status, but it's not the immediate concern when administering this antiemetic medication.

Choice D rationale:

Checking vital signs is essential before giving any medication to ensure the client's overall stability and to detect any potential contraindications or adverse reactions.
