NAPLEX (North American Pharmacist Licensure Examination) Practice Exam

Which opioid allergy commonality is given in the text?

1. Drugs ending in -fen

2. Drugs with -COD or -MORPH in name

3. Drugs starting with Tram-

4. Medications in liquid form

The correct answer is: Drugs with -COD or -MORPH in name

The correct answer is B. Drugs with -COD or -MORPH in the name are commonly associated with opioid allergies. Opioid medications like codeine and morphine fall into this category. This commonality is important for healthcare providers to be aware of when managing patients with known or suspected opioid allergies. Options A, C, and D are not accurate commonalities for opioid allergies. Drugs ending in -fen (Option A) may refer to medications like fentanyl, which is an opioid but not necessarily a commonality for opioid allergies. Drugs starting with Tram- (Option C) may be referring to tramadol, another opioid, but not all drugs starting with Tram- are commonly associated with opioid allergies. Medications in liquid form (Option D) are not specifically linked to opioid allergies; the form of the medication does not determine the likelihood of an allergic reaction.
