A client who is on sulfonamide therapy is about to be discharged.
Which of the following precautions should the nurse instruct the client to follow to reduce the effects of photosensitivity?
Wear protective clothing and sunscreen when outside.
Increase fluid intake.
Avoid lights while indoors.
Wear protective footwear.
The Correct Answer is A
Choice A rationale:
Wear protective clothing and sunscreen when outside. Rationale: Sulfonamide antibiotics, a type of medication mentioned in the question, can increase the skin's sensitivity to sunlight, leading to photosensitivity reactions. To reduce the effects of photosensitivity, the client should be instructed to wear protective clothing that covers the skin and to apply sunscreen with a high sun protection factor (SPF) when going outdoors. This helps shield the skin from harmful UV rays, reducing the risk of sunburn and other adverse reactions.
Choice B rationale:
Increase fluid intake. Rationale: Increasing fluid intake is a general recommendation for clients taking sulfonamide antibiotics to minimize the risk of crystalluria, a side effect that can result from inadequate hydration. Crystalluria is the formation of crystals in the urine and can lead to kidney stones. While staying hydrated is essential, it is not specifically related to reducing photosensitivity, which is the focus of this question.
Choice C rationale:
Avoid lights while indoors. Rationale: Avoiding lights while indoors is not a standard precaution to reduce the effects of photosensitivity caused by sulfonamide antibiotics. Photosensitivity primarily refers to the skin's heightened sensitivity to sunlight. Being indoors under regular lighting conditions should not significantly impact photosensitivity. The key precautions are related to outdoor sun exposure.
Choice D rationale:
Wear protective footwear. Rationale: Wearing protective footwear is not a standard precaution to reduce photosensitivity effects caused by sulfonamide antibiotics. Photosensitivity primarily affects the skin, not the feet. While protective footwear may be recommended in specific situations, such as in a construction or industrial setting, it is not directly related to reducing the risk of photosensitivity reactions.

Correct Answer is B
Explanation
Choice A rationale:
Staphylococcus is not typically associated with causing diarrhea or harm to the intestinal mucosa. Staphylococcus is more commonly linked to skin and soft tissue infections, as well as food poisoning.
Choice B rationale:
Salmonella is a bacterium that can harm the intestinal mucosa and is a common cause of foodborne illness. It can lead to symptoms such as diarrhea, abdominal pain, fever, and vomiting, which can be severe and potentially damage the intestinal lining.
Choice C rationale:
Streptococcus is not a common cause of diarrhea or harm to the intestinal mucosa. Streptococcus species are more often associated with respiratory and throat infections.
Choice D rationale:
Pseudomonas is not a typical cause of diarrhea or harm to the intestinal mucosa. Pseudomonas is known for its association with healthcare-associated infections and is more often linked to conditions like pneumonia and urinary tract infections.
Correct Answer is B
Explanation
Choice A rationale:
Administering a combination of drugs in TB treatment is not primarily aimed at preventing the incidence of liver dysfunction. The combination therapy's main objective is to address the complex nature of Mycobacterium tuberculosis infections and the potential development of antibiotic resistance.
Choice B rationale:
The nurse should explain that the primary reason for administering a combination of drugs is to slow down bacterial resistance. When TB is treated with a single drug, the bacteria can quickly develop resistance to that drug. Using a combination of drugs with different mechanisms of action makes it more difficult for the bacteria to develop resistance. This is a fundamental principle in the treatment of TB.
Choice C rationale:
Slowing the body's resistance to medication is not a goal in TB treatment. The focus is on preventing the development of resistance in the bacteria, not the body's response to the medication.
Choice D rationale:
While TB treatment aims to prevent the further spread of the disease, the primary reason for using a combination of drugs is to address bacterial resistance. Preventing the spread of TB is an important secondary benefit of effective treatment.
