An adult exposed to tuberculosis is scheduled to begin prophylactic treatment with isoniazid. Which information is most important for the nurse to note before administering the initial dose?
Conversion of the client's PPD test from negative to positive
History of intravenous drug abuse
Current diagnosis of hepatitis B
Length of time of the exposure to tuberculosis
The Correct Answer is C
Choice A: Conversion of the client's PPD test from negative to positive is not the most important information for the nurse to note, as this is an expected finding for a client who has been exposed to tuberculosis and does not affect the administration of isoniazid. This is a distractor choice.
Choice B: History of intravenous drug abuse is not the most important information for the nurse to note, as this is not directly related to the use of isoniazid and does not contraindicate its administration. This is another distractor choice.
Choice C: Current diagnosis of hepatitis B is the most important information for the nurse to note, as this can increase the risk of hepatotoxicity and liver damage from isoniazid, which requires close monitoring and possible dose adjustment. Therefore, this is the correct choice.
Choice D: Length of time of the exposure to tuberculosis is not the most important information for the nurse to note, as this does not influence the dosage or frequency of isoniazid and does not indicate any complication or adverse reaction. This is another distractor choice.

Correct Answer is D
Explanation
Choice D is correct because frequent exposure to sunlight is the most significant environmental factor when planning care for a client with osteomalacia. Osteomalacia is a condition in which the bones become soft and weak due to inadequate mineralization, often caused by vitamin D deficiency. Vitamin D is essential for calcium absorption and bone health, and it can be synthesized by the skin when exposed to sunlight. The nurse should encourage the client to get at least 15 minutes of sunlight per day or take vitamin D supplements as prescribed.
Choice A is incorrect because quiet, calm surroundings are not a specific environmental factor for a client with osteomalacia. Quiet, calm surroundings may help reduce stress and promote relaxation, but they do not affect bone mineralization or vitamin D synthesis.
Choice B is incorrect because stimulating sounds and activity are not a specific environmental factor for a client with osteomalacia. Stimulating sounds and activity may help improve mood and cognition, but they do not affect bone mineralization or vitamin D synthesis.
Choice C is incorrect because cool, moist air is not a specific environmental factor for a client with osteomalacia. Cool, moist air may help relieve respiratory symptoms or allergies, but it does not affect bone mineralization or vitamin D synthesis.
Correct Answer is C
Explanation
Choice A: Yellow-tinged sputum is not a serious adverse effect of linezolid. It may indicate an infection or inflammation in the respiratory tract, but it does not require immediate attention from the health care provider.
Choice B: Nausea and headache are common side effects of linezolid. They are usually mild and self-limiting, and they can be managed with supportive measures such as hydration, rest, and analgesics.
Choice C: Watery diarrhea is a sign of pseudomembranous colitis, a potentially life-threatening complication of linezolid. It is caused by an overgrowth of Clostridium difficile bacteria in the colon, which produce toxins that damage the intestinal mucosa. It can lead to dehydration, electrolyte imbalance, sepsis, and perforation. The nurse should report this finding to the health care provider immediately and stop the linezolid infusion.
Choice D: Increased fatigue is not a specific or serious adverse effect of linezolid. It may be related to the underlying infection, anemia, or other factors. It does not require urgent intervention from the health care provider.
