Accepted Answer

Discoloration of the urine

Answer

Phenazopyridine is a urinary analgesic used to relieve pain, burning, and discomfort associated with urinary tract infections. A very common and expected side effect of this medication is the discoloration of urine, typically turning it to an orange or reddish-brown color. Patients should be informed of this harmless but noticeable effect.

Question 2

Which of the following medications should pregnant women avoid taking?

Accepted Answer

Tetracycline

Answer

Tetracycline antibiotics are contraindicated during pregnancy because they can cause permanent tooth discoloration and inhibit bone growth in the developing fetus. These adverse effects are due to tetracycline's ability to chelate calcium and deposit in calcifying tissues. Safer antibiotic alternatives are typically chosen for pregnant women.

Question 3

All of the following drugs are categorized as NSAIDs, with the exception of which one?

Accepted Answer

Acetaminophen

Answer

Acetaminophen (Tylenol) is an analgesic and antipyretic, meaning it relieves pain and reduces fever. However, it is not classified as a Nonsteroidal Anti-inflammatory Drug (NSAID). NSAIDs, such as aspirin, ibuprofen, and naproxen, work by inhibiting cyclooxygenase enzymes to reduce inflammation, pain, and fever, a mechanism distinct from acetaminophen's action.
