The nurse is planning education for a client with a new beta-blocker prescription. Which information should the nurse plan to include in the education?

A. Hold medication if heart rate is greater than 60 bpm: Beta-blockers are typically held if the heart rate is less than 60 bpm, not greater. Administering the medication when the heart rate is above 60 bpm is generally safe, so this instruction is inaccurate. B. Report signs of liver damage, including dark-colored urine: While some medications can affect liver function, beta-blockers rarely cause liver toxicity. Monitoring for liver damage is not a standard teaching point for typical beta-blocker use unless the client has preexisting liver disease. C. Stop taking this medication if you experience dizziness: Abruptly stopping beta-blockers can precipitate rebound hypertension or tachycardia, which can be dangerous. Clients should be instructed to notify their healthcare provider rather than independently discontinuing the medication. D. Sexual dysfunction may occur with this medication: Beta-blockers can cause side effects such as erectile dysfunction or decreased libido. Educating the client about potential sexual side effects helps set expectations and encourages open discussion with the healthcare provider if symptoms develop.
