Pharmacy Technician Certification Exam Practice Question

Correct Answer: B

Rationale: Mercaptopurine is classified as a high-alert medication due to its potential for severe toxicity and significant drug interactions, particularly in patients with compromised immune systems or those undergoing chemotherapy.

Meloxicam, while an NSAID, is commonly used and generally considered safe when used appropriately. Metronidazole is an antibiotic with known side effects, but it is not classified as high-alert. Methocarbamol, a muscle relaxant, poses fewer risks and is not typically associated with severe adverse effects in the community setting. Therefore, among the options, mercaptopurine requires heightened awareness and monitoring.
