Practice Question
A 21-year-old college student is prescribed doxycycline for acne vulgaris. The patient reports taking the medication with breakfast, which includes cereal, orange juice, and milk. Two weeks later, she returns complaining that her acne has not improved and she has been experiencing frequent sunburns even with minimal sun exposure. What is the most appropriate nursing intervention?
Answer Choices:
Correct Answer:
Educate the patient on avoiding dairy and using sunscreen due to photosensitivity
Rationale:
🟡 Doxycycline, a tetracycline-class antibiotic, is known to have decreased absorption when taken with dairy products, calcium, or iron. The milk and cereal with milk consumed during breakfast likely interfered with the drug’s gastrointestinal absorption, reducing its effectiveness and resulting in persistent acne.
🟡 Additionally, doxycycline causes photosensitivity, making patients more prone to sunburn with even minimal sun exposure. This explains the patient's complaint of frequent sunburns.
🟡 The correct nursing action is to educate the patient to avoid taking the medication with dairy, separate dosing from calcium-containing products by several hours, and use sun protection (e.g., sunscreen, protective clothing).
🟡 Increasing the dose or switching the drug would not be the first step without first addressing the dietary interaction and sun exposure, which are likely responsible for the lack of efficacy and side effects.
