A nurse in a healthcare provider's clinic is caring for a client who reports erectile dysfunction and requests a prescription for sildenafil. Which of the following medications currently prescribed for the client is a contraindication to taking sildenafil?
Pantoprazole
Isosorbide mononitrate
Acetylsalicylic acid
Atorvastatin sodium
The Correct Answer is B
A. Pantoprazole: This medication is a proton pump inhibitor used to treat acid-related disorders and does not interact adversely with sildenafil.
B. Isosorbide mononitrate: This is correct. Isosorbide mononitrate is a nitrate used to treat angina. Combining it with sildenafil can lead to severe hypotension due to their additive vasodilatory effects.
C. Acetylsalicylic acid: This is incorrect. Acetylsalicylic acid (aspirin) is used for pain relief and cardiovascular protection and does not contraindicate sildenafil use.
D. Atorvastatin sodium: This is incorrect. Atorvastatin is a statin used to manage cholesterol levels and does not contraindicate sildenafil use.

A. Hormone therapy decreases the risk of cardiovascular events: This is incorrect. Hormone therapy has been associated with an increased risk of cardiovascular events, such as heart attacks and strokes, especially in older women or those with preexisting risk factors.
B. Hormone therapy may prevent osteoporotic fractures: This is correct. Hormone therapy can help maintain bone density and reduce the risk of osteoporotic fractures, which is beneficial after a total hysterectomy.

Correct Answer is C
Explanation
A. Anthrax: This is incorrect. While a vaccine is available for anthrax, it is generally administered as a pre-exposure prophylaxis, not as a treatment following exposure.
B. Sarin: This is incorrect. Sarin is a nerve agent for which there is no vaccine. Treatment focuses on immediate decontamination and administration of antidotes like atropine.
C. Smallpox: This is correct. A vaccine for smallpox is administered following exposure as a post-exposure prophylaxis, as smallpox is a virus for which immediate vaccination can help prevent the disease.
D. Botulism: This is incorrect. Botulism is treated with antitoxin rather than a vaccine. There is no post-exposure vaccine available for botulism.
