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

Answer and Explanation

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 D

Explanation

A. Initiate seizure precautions: Dopamine administration does not typically require seizure
precautions. The focus should be on monitoring for adverse effects related to blood pressure and urinary output.
B. Monitor serum potassium frequently: While electrolyte imbalances can occur with dopamine administration, the priority is to monitor urinary output as dopamine affects renal perfusion and urine output.
C. Assess pupillary response to light hourly: Monitoring pupillary response is important in some situations, but it's not the primary concern with dopamine administration.
D. Measure urinary output every hour: Correct! Dopamine is administered to improve renal perfusion and increase urine output in hypotensive patients. Monitoring urinary output every
hour is essential to assess the effectiveness of dopamine therapy and detect any signs of renal dysfunction or worsening hypotension.

A. Increase the intake of dark green leafy vegetables while taking warfarin. B. Eat two servings of raw dark green leafy vegetables daily and continue for 30 days after warfarin therapy is completed. C. Eat approximately the same amount of leafy green vegetables daily so the amount of vitamin K consumed is consistent. D. Avoid eating all foods that contain any vitamin K because it is an antagonist of warfarin.

Correct Answer is C

Explanation

A. Increasing the intake of dark green leafy vegetables while taking warfarin can affect INR levels due to their high vitamin K content, potentially increasing the risk of bleeding.
B. Eating two servings of raw dark green leafy vegetables daily and continuing for 30 days after warfarin therapy is completed is not recommended as it may affect INR levels.
C. Eating approximately the same amount of leafy green vegetables daily helps maintain consistent vitamin K intake, which is important for keeping INR levels stable while on warfarin therapy.
D. Avoiding all foods containing vitamin K is not necessary and may lead to nutritional
deficiencies; instead, it's important to consume a consistent amount of vitamin K-containing foods.
