A nurse is caring for a client who has tuberculosis and is prescribed rifampin, an antitubercular drug. The nurse should instruct the client about which potential side effect of rifampin?

Red-orange discoloration of body fluids

Metallic taste in mouth

Photosensitivity reaction

Ototoxicity.

Answer and Explanation

The Correct Answer is A

The nurse should instruct the client about this possibility and reassure them that it is harmless and will disappear when the medication is discontinued.

Choice B is wrong because metallic taste in mouth is not a side effect of rifampin, but of metronidazole, an antibiotic used to treat infections caused by anaerobic bacteria or protozoa.

Choice C is wrong because photosensitivity reaction is not a side effect of rifampin, but of tetracycline, an antibiotic used to treat acne and other infections.

Choice D is wrong because ototoxicity is not a side effect of rifampin, but of aminoglycosides, a class of antibiotics used to treat serious infections caused by gram-negative bacteria.

Ototoxicity can cause hearing loss or balance problems.

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. Instruct the client to swish and swallow the medication B. Administer the medication with a dropper to avoid aspiration C. Dilute the medication with water before giving it to the client D. Give the medication after meals to increase its effectiveness.

Correct Answer is A

Explanation

This is because nystatin suspension is an antifungal medication that works by coating the oral mucosa and killing the candida organisms.Swishing and swallowing the medication ensures that it reaches all the affected areas in the mouth and throat.

Choice B is wrong because administering the medication with a dropper to avoid aspiration is not necessary for a client who has oral candidiasis.

The client should be able to swish and swallow the medication without difficulty.

Choice C is wrong because diluting the medication with water before giving it to the client reduces its effectiveness and concentration.

The medication should be given undiluted for optimal results.

Choice D is wrong because giving the medication after meals to increase its effectiveness is not accurate.The medication should be given at least 30 minutes before or after meals to avoid interference with food or beverages.
