A nurse is providing teaching to a client who has a new prescription for lorazepam. Which of the following statements by the client indicates an understanding of the teaching?

A. "This medication may cause me to experience a metallic taste in my mouth.": Lorazepam is a benzodiazepine and does not commonly cause a metallic taste. This statement reflects a misunderstanding of common adverse effects associated with the medication. B. "This medication can cause my potassium level to decrease.": Lorazepam does not affect electrolyte levels such as potassium. Monitoring potassium is not typically necessary with this medication, so this statement is inaccurate. C. "This medication can cause drowsiness.": Drowsiness is a common side effect of lorazepam due to its sedative properties. Understanding this effect helps the client anticipate and manage daytime sleepiness and avoid activities requiring alertness, demonstrating correct comprehension of teaching. D. "This medication may cause me to lose weight.": Lorazepam is not associated with weight loss. Clients should be informed about the expected side effects, and weight changes are not typical with this medication, making this statement incorrect.
