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

Answer and Explanation

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 C

Explanation

Choice C is correct because repositioning the infant every 2 hours can help expose different parts of the skin to the phototherapy light and increase the effectiveness of the treatment. The nurse should also check the skin for signs of irritation or burns.

Choice A is incorrect because feeding the infant every 4 hours is not specific to home phototherapy. The infant may need more frequent feedings depending on their hunger cues and weight gain.

Choice B is incorrect because performing diaper changes under the light is not necessary and may expose the infant's genitals to excessive light and heat. The nurse should advise the parents to cover the infant's eyes and genitals with protective shields during phototherapy.

Choice D is incorrect because covering the infant with a receiving blanket can reduce the exposure of the skin to the phototherapy light and decrease the effectiveness of the treatment. The nurse should advise the parents to keep the infant unclothed or only in a diaper during phototherapy.

A. Yellow-tinged sputum B. Nausea and headache C. Watery diarrhea D. Increased fatigue

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.
