A client 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 exposure to tuberculosis
The Correct Answer is C
A. Conversion of the PPD test from negative to positive indicates exposure to tuberculosis but does not contraindicate the administration of isoniazid. It may actually indicate the need for prophylactic treatment.
B. A history of intravenous drug abuse is not directly related to the administration of isoniazid. However, it may be important for assessing risk factors for tuberculosis transmission and adherence to treatment.
C. Isoniazid can cause hepatotoxicity, so it is essential to assess for pre-existing liver conditions such as hepatitis B before administering the medication. Hepatitis B may increase the risk of liver damage associated with isoniazid.
D. The length of time of exposure to tuberculosis is important for assessing the risk of infection and determining the need for prophylactic treatment but does not impact the administration of isoniazid.

Correct Answer is A
Explanation
A. Reposition the infant every 2 hours: This ensures that all areas of the infant's skin receive equal exposure to the phototherapy light, which is important for the effective treatment of jaundice.
B. Cover with a receiving blanket: This is incorrect because the phototherapy light needs to reach the infant's skin directly. Covering the infant with a blanket would block the light and reduce the effectiveness of the treatment.
C. Perform diaper changes under the light: While it is important to minimize the time the infant is away from the phototherapy light, diaper changes should be done quickly and efficiently, not necessarily under the light, to ensure cleanliness and to prevent any potential discomfort or safety issues.
D. Feed the infant every 4 hours: Feeding the infant is important, but the frequency of feeding should be based on the infant's needs and not specifically tied to the phototherapy schedule. Additionally, frequent feeding can help promote bowel movements, which can aid in the excretion of bilirubin.
