Final answer:
Dizziness is a potential adverse effect of taking labetalol.
Step-by-step explanation:
The nurse should identify dizziness as a potential adverse effect of taking labetalol, a medication commonly used in postpartum clients.
Labetalol is a beta-blocker that is known to cause dizziness in some individuals as a side effect. The medication works by blocking certain receptors in the body, which can affect blood flow and blood pressure regulation, leading to dizziness.
Other potential adverse effects of labetalol may include fatigue, low blood pressure, and abnormal heart rhythms. It is important for the nurse to monitor the client closely for any signs of these adverse effects.
