The nurse is obtaining a medication history of a 48-year-old patient with an ear infection who is to receive penicillin therapy.
The patient reports taking a beta-adrenergic blocker for his hypertension.
The nurse would identify that this patient is at increased risk for which of the following if penicillin is administered?

Choice A rationale:

Constipation Constipation is not a common adverse reaction to ciprofloxacin. While gastrointestinal side effects can occur with this medication, constipation is not typically associated with it. Ciprofloxacin is more likely to cause diarrhea or other gastrointestinal issues rather than constipation.

Choice B rationale:

Nausea Nausea is a common adverse reaction to ciprofloxacin. Ciprofloxacin can irritate the stomach lining, leading to feelings of nausea. It is important to educate the client about this potential side effect, as nausea can affect their compliance with the medication.

Choice C rationale:

Sedation Sedation is not a common adverse reaction to ciprofloxacin. This medication is not known for causing drowsiness or sedation. In fact, it is often prescribed to be taken twice a day, and sedation could interfere with the client's daily activities.

Choice D rationale:

Dry mouth Dry mouth is not a common adverse reaction to ciprofloxacin. While dry mouth can be a side effect of some medications, it is not typically associated with ciprofloxacin. Instead, ciprofloxacin is more likely to cause gastrointestinal symptoms and potential taste alterations.
