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 A
Explanation
The correct answer is A. Flushed, peeling skin
Choice A reason: Flushed, peeling skin is a classic sign of scarlet fever, which is a condition that can arise from Streptococcal pharyngitis. Scarlet fever is characterized by a red rash that can cover most of the body and may lead to the skin peeling. This symptom is a direct reaction to the toxins produced by the Streptococcal bacteria.
Choice B reason: Red bumps across the chest could be indicative of many conditions and are not specifically characteristic of the reaction to toxins produced by Streptococcal bacteria. While a rash is common in scarlet fever, it typically starts on the face or neck and spreads to the rest of the body, rather than presenting as isolated red bumps.
Choice C reason: A white coating on the tongue, often referred to as “strawberry tongue,” is indeed associated with scarlet fever. However, it is not the clearest indication of a reaction to the toxins. The white coating usually precedes the strawberry-like appearance, where the tongue becomes red and bumpy.
Choice D reason: While a high fever is a symptom of scarlet fever, it is not specific to the reaction to toxins from Streptococcal bacteria, as many infections can cause high fevers. The term “protracted” suggests a prolonged fever, which could be seen in various conditions.
Correct Answer is C
Explanation
Choice A: Assessing pupillary response to light hourly is not related to dopamine administration. Dopamine does not affect the pupils or the cranial nerves that control them.
Choice B: Initiating seizure precautions is not necessary for a client receiving dopamine. Dopamine does not lower the seizure threshold or cause convulsions.
Choice C: Measuring urinary output every hour is an important intervention for a client receiving dopamine. Dopamine increases blood pressure and cardiac output, which improves renal perfusion and urine production. Urinary output is an indicator of the effectiveness of dopamine therapy and renal function.
Choice D: Monitoring serum potassium frequently is not directly related to dopamine administration. Dopamine does not affect potassium levels or cause hyperkalemia or hypokalemia. However, potassium levels may be affected by other factors such as fluid balance, renal function, and medications.
