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. Obtain a capillary glucose level: The symptoms of jitteriness and tachypnea in a newborn could be indicative of hypoglycemia, so the first action should be to assess the glucose level to determine if hypoglycemia is the cause.
B. Feed 30 mL of 10% dextrose in water: While providing dextrose may be necessary if hypoglycemia is confirmed, assessing the glucose level should be done first to guide appropriate treatment.
C. Wrap tightly in a warm blanket: While keeping the newborn warm is important, it is not the first action to take in this scenario where the newborn is displaying signs of possible hypoglycemia.
D. Encourage the mother to breastfeeD Breastfeeding may help increase the newborn's glucose level, but the priority is to assess the glucose level first to determine if hypoglycemia is present.
Correct Answer is D
Explanation
A. Osmolality: Osmolality measures the concentration of solutes in the blood and is not typically affected by naproxen or indicative of the reported symptoms.
B. Serum calcium: While naproxen can cause gastrointestinal irritation and ulceration, it does not typically affect serum calcium levels. Monitoring serum calcium would not directly address the client's reported symptoms.
C. Erythrocyte sedimentation rate (ESR): ESR is a nonspecific marker of inflammation and is not directly related to the reported symptoms of stomach pain, weakness, and fatigue associated with naproxen use.
D. Hemoglobin: Naproxen, a nonsteroidal anti-inflammatory drug (NSAID), can cause gastrointestinal bleeding, which may lead to anemia and a decrease in hemoglobin levels. Monitoring hemoglobin levels can help assess for gastrointestinal bleeding in this client who is experiencing stomach pain and weakness/fatigue.
