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 D

Explanation

This statement indicates a need for further teaching because linezolid should be taken for the full prescribed course of treatment, even if the symptoms improve or resolve.Stopping the medication too soon can lead to bacterial resistance or recurrence of the infection.

Choice A is wrong because it is a correct statement.Linezolid can cause optic neuropathy or vision changes, so patients should report any changes in their vision to their doctor.

Choice B is wrong because it is a correct statement.

Linezolid can interact with foods that contain tyramine, such as cheese and red wine, and cause a hypertensive crisis.Patients should avoid eating foods that contain tyramine while taking linezolid and for two weeks after stopping the medication.

Choice C is wrong because it is a correct statement.Linezolid can be taken with or without food, but taking it on an empty stomach may help with absorption and effectiveness.

A. Development of medication resistance in the host B. Over-riding of the minimum bactericidal concentration C. Incorrect dosing, which contributes to ribosome mutations D. Transfer of DNA coding to other bacteria E. Spontaneous mutation in the microbial genome.

Correct Answer is ["D","E"]

Explanation

A microbe acquires antibiotic resistance by transferring DNA coding to other bacteria or by spontaneous mutation in the microbial genome.

These genetic changes allow the microbe to survive the effects of the antibiotic and pass on the resistance to its offspring.

ChoiceAis wrong because the host does not develop medication resistance, but the microbe does.

ChoiceBis wrong because the minimum bactericidal concentration (MBC) is the lowest concentration of an antibiotic needed to kill 99.9% of bacteria, not a mechanism of resistance.

ChoiceCis wrong because incorrect dosing does not cause ribosome mutations, but may promote the emergence of drug-resistant microbes by exposing them to suboptimal levels of the antibiotic.
