Famotidine
Aspirin
Metronidazole

B. Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) used for pain relief, fever reduction, and anti-inflammatory purposes. It does not contain sulfonamide and is not contraindicated for patients with sulfonamide allergies.
C. Metronidazole is an antibiotic used to treat various infections, including those of the gastrointestinal tract and the reproductive system. It does not contain sulfonamide and is safe for patients with sulfonamide allergies.

Correct Answer is D
Explanation
A. “You should take this medication once each day at bedtime.” This statement is incorrect because rifampin is typically taken on an empty stomach, either 1 hour before or 2 hours after a meal, to ensure optimal absorption. Taking it at bedtime is not a standard recommendation.
B. “You can continue to wear soft contact lenses while taking this medication.” This statement is incorrect because rifampin can cause discoloration of bodily fluids, including tears, which can stain soft contact lenses. Patients are usually advised to avoid wearing soft contact lenses during treatment.
C. “This medication will not interfere with the effectiveness of oral contraceptives.” This statement is incorrect because rifampin is known to reduce the effectiveness of oral contraceptives. Patients should be advised to use an alternative or additional form of contraception while taking rifampin.
D. “Your urine will turn orange while you are taking this medication.” This statement is correct. Rifampin commonly causes a harmless discoloration of urine, sweat, saliva, and tears to an orange or reddish color. Patients should be informed about this side effect to avoid unnecessary concern.
Correct Answer is C
Explanation
A. Diarrhea is a common adverse effect of opioids. This statement is incorrect. Opioids commonly cause constipation, not diarrhea, as they slow down gastrointestinal motility.
B. Opioids can increase urinary output. This statement is incorrect. Opioids can actually cause urinary retention rather than increasing urinary output.
C. Long-term use of opioids may cause dependence. This statement is correct. Long-term use of opioids can lead to physical dependence, where the body adapts to the drug, and withdrawal symptoms occur if the drug is abruptly discontinued.
D. Tolerance to opioids will require a decreased dose. This statement is incorrect. Tolerance to opioids means that over time, higher doses of the drug are needed to achieve the same level of pain relief, not a decreased dose.
