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.

Correct Answer is D
Explanation
A. Rub the skin completely dry following a decontamination shower: This is incorrect. The skin should be patted dry, not rubbed, to avoid further irritation.
B. Prepare to administer amyl nitrate: This is incorrect. Amyl nitrate is used for cyanide poisoning, not sarin gas exposure.
C. Provide respiratory support with a plastic airway: While respiratory support may be needed, the priority in sarin gas exposure involves addressing symptoms and potential seizures.
D. Initiate seizure precautions: Sarin gas is a nerve agent that can cause seizures due to its effect on the nervous system. Seizure precautions are necessary for clients exposed to sarin gas.
Correct Answer is ["675"]
Explanation
To calculate the appropriate dose of vancomycin, follow these steps:
- Convert pounds to kilograms:
- 198 lb (1 kg / 2.2 lb) = 90 kg
- Calculate the total daily dose:
- 15 mg/kg/day 90 kg = 1350 mg/day
- Determine the dose per administration:
- 1350 mg/day / 2 doses/day = 675 mg/dose
