A nurse is teaching a client who has been prescribed tetracycline, a tetracycline antibiotic, for acne vulgaris.
Which of these instructions should the nurse include in the teaching? (Select all that apply.)

Take the drug on an empty stomach.

Avoid dairy products while taking this drug.

Use sunscreen or avoid exposure to sunlight.

Drink plenty of fluids while taking this drug.

Report any vaginal itching or discharge.

Answer and Explanation

Correct Answer : A,B,C,D

The nurse should include these instructions in the teaching because:

• Tetracycline should be taken on an empty stomach to avoid interference with absorption.

• Dairy products should be avoided while taking this drug because they contain calcium, which can form insoluble complexes with tetracycline and reduce its effectiveness.

• Sunscreen or sun avoidance should be used while taking this drug because it can cause photosensitivity, which increases the risk of sunburn and skin damage.

• Plenty of fluids should be drunk while taking this drug because it can cause nephrotoxicity, which is damage to the kidneys.

Choice E is wrong because vaginal itching or discharge is not a common side effect of tetracycline. It may indicate a superinfection, which is a secondary infection caused by the disruption of normal flora by antibiotics.

This should be reported to the health care provider as soon as possible.

Correct Answer is B

Explanation

A superinfection is defined as an infection that comes second to an initial infection and is often caused by the elimination of normal flora by an antibiotic.

Normal flora are the microorganisms that normally live in the human body and help prevent the growth of harmful pathogens.

When an antibiotic kills the normal flora, it creates an opportunity for other microorganisms to overgrow and cause a new infection.

Choice A is wrong because a resistant infection is an infection that does not respond to an antibiotic due to the presence of resistant bacteria.

Resistance can occur when bacteria mutate or acquire genes that make them able to survive the antibiotic.

Choice C is wrong because a nosocomial infection is an infection that is acquired in a hospital or health care setting.

Nosocomial infections can be caused by various factors, such as exposure to contaminated equipment, poor hygiene practices, or transmission from other patients or staff.

Choice D is wrong because an allergic reaction is an immune response to a foreign substance that is not harmful.

Allergic reactions can occur when a person is sensitive to an antibiotic or any other drug.

Symptoms of an allergic reaction may include rash, itching, swelling, or difficulty breathing.

A. Take the medication with or without food B. Report any signs of jaundice or dark urine C. Avoid drinking grapefruit juice while taking this medication D. Complete the full course of therapy as prescribed E. Store the medication in a cool and dry place.

Correct Answer is ["B","C","D"]
