A client with nasal congestion receives a prescription for phenylephrine 10 mg PO every 4 hours. Which client condition should the nurse report to the healthcare provider before administering the medication?

A. Hypertension: Phenylephrine is a decongestant that works by constricting blood vessels, which can raise blood pressure. In clients with hypertension, phenylephrine can exacerbate their condition and lead to potentially serious complications. Therefore, the nurse should report hypertension to the healthcare provider before administering phenylephrine to ensure that it is used safely or to consider alternative treatments. B. Bronchitis: While bronchitis can cause nasal congestion, it is not a contraindication for phenylephrine. However, if the client has bronchitis with significant respiratory distress, the nurse should be cautious, as decongestants can sometimes worsen breathing issues, but it is not the primary condition to report. C. Edema: Edema, or swelling, is not a direct contraindication for phenylephrine. However, it is important to consider the underlying cause of the edema and whether it could impact the use of decongestants. Nonetheless, hypertension remains the more critical condition to address before administering this medication. D. Diarrhea: Diarrhea is not a condition that typically contraindicates the use of phenylephrine. While it is important to monitor the client's overall condition, diarrhea does not directly interact with or affect the safety of phenylephrine use in the same way hypertension does.
