A nurse is teaching a patient about the use of sildenafil [Viagra] for erectile dysfunction. Which statement by the patient indicates understanding of the teaching?

"This drug may cause me to have an erection when I don't want one."

"If my erection lasts longer than 6 hours, I should contact my provider."

"If I have chest pain with sildenafil, I can use my nitroglycerin as prescribed."

"I should take this drug 5 minutes before sexual activity."

Answer and Explanation

The Correct Answer is B

A. While sildenafil can cause erections, it does not typically lead to unwanted erections; it requires sexual stimulation to be effective.
B. An erection lasting longer than 6 hours, known as priapism, is a serious side effect and requires immediate medical attention, indicating the patient understands this risk.
C. Using nitroglycerin with sildenafil can lead to dangerous drops in blood pressure, and patients should be advised to avoid this combination.
D. Sildenafil should be taken about 30 minutes to 1 hour before sexual activity for best results, not just 5 minutes prior.

Correct Answer is C

Explanation

A. Hydrochlorothiazide is a thiazide diuretic that can be used for hypertension and edema but is not specifically indicated for open-angle glaucoma.
B. Furosemide is a loop diuretic used primarily for fluid overload conditions and does not have a specific role in the treatment of open-angle glaucoma.
C. Acetazolamide is a carbonic anhydrase inhibitor that reduces aqueous humor production and is specifically used to lower intraocular pressure in clients with open-angle glaucoma.
D. Spironolactone is a potassium-sparing diuretic used mainly for conditions like heart failure and hypertension, and it is not indicated for the treatment of open-angle glaucoma.

A. "This medication is addictive, so you will need to discontinue it in six months." B. "Your provider may prescribe a diuretic if you have trouble urinating while taking lithium." C. "We will monitor your lithium levels closely while you are taking this medication." D. "Weight gain should be reported to your provider as an indication of lithium toxicity."

Correct Answer is C

Explanation

A. Lithium is not considered addictive in the traditional sense, and it does not need to be discontinued after six months unless clinically indicated.
B. Diuretics are generally avoided in patients taking lithium due to the risk of lithium toxicity from altered renal clearance, rather than being a routine prescription for difficulty urinating.
C. Close monitoring of lithium levels is crucial to avoid toxicity and ensure therapeutic efficacy, making this statement correct and essential for the patient’s education.
D. While weight gain can occur with lithium therapy, it is not an indicator of lithium toxicity; symptoms of toxicity include nausea, tremors, and confusion rather than weight gain.
