Final answer:
The nurse should suggest that the patient discusses the issue with their physician, who can adjust the medication or dosage to address sexual dysfunction caused by antihypertensive drugs, which is a known side effect.
Step-by-step explanation:
The most appropriate response by the nurse to a 56-year-old man who has experienced sexual dysfunction after starting antihypertensive drugs is: 'The physician can work with you on changing the dose and/or drugs' (option b). This acknowledges the side effect and provides an actionable next step, suggesting that a consultation with the physician could lead to adjustments in medication that can alleviate the issue without compromising the treatment of hypertension.
Erectile dysfunction is a known potential side effect of certain blood pressure medications. Beta-blockers and diuretics, for instance, can cause erectile dysfunction, and if a patient experiences these unwanted effects, a doctor may consider prescribing a different class of blood pressure medication. This response maintains a professional tone, informs the patient that sexual dysfunction can occur with antihypertensive therapy, and supports patient-physician collaboration. It is important to manage side effects effectively, as they can impact adherence to medication regimens and therefore the overall management of hypertension.
