A client who had a kidney transplant last week is receiving cyclosporine. This morning the client reports experiencing a headache and blurred vision. Based on which assessment finding should the nurse withhold the medication until the healthcare provider (HCP) is notified?

A. Take the medication an hour after antacids: Antacids can interfere with the absorption of cimetidine, so spacing them apart is a correct approach. This statement indicates appropriate understanding of medication timing and does not require further instruction.

B. Notify the healthcare provider (HCP) of lethargy: Cimetidine can cause central nervous system effects like confusion or lethargy, particularly in older adults or those with renal impairment. Reporting such symptoms is appropriate and reflects safe medication awareness.

C. Monitor for any signs of sexual dysfunction: Cimetidine has been associated with gynecomastia, decreased libido, and impotence in some cases. The client should be aware of and monitor for these potential effects.

D. Decrease cigarette use to a pack per day: Smoking impairs ulcer healing and increases gastric acid secretion, which can counteract the effects of cimetidine. Reducing to a pack per day is still harmful; the client should be encouraged to stop smoking entirely, not just cut back.

A. Expectorating bronchial secretions: This outcome is more closely associated with expectorants, which loosen mucus in the airways. Antitussives, by contrast, suppress the cough reflex and are not intended to increase mucus clearance or productive coughing.

B. Reports reduced nasal discharge: Reduced nasal discharge is typically an effect of decongestants or antihistamines, not antitussive medications. Antitussives target the cough reflex, not nasal secretions.

C. Able to sleep through the night: While improved sleep may result from reduced coughing, it is a secondary and nonspecific outcome. The ability to sleep could be influenced by other factors such as overall symptom relief, not necessarily the effectiveness of the antitussive alone.

D. Denies having coughing spells: Antitussives are designed to suppress the cough reflex, particularly in cases of dry, nonproductive cough. A report of no more coughing spells directly reflects the intended therapeutic effect of the medication.
