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 B

Explanation

A. Explaining that the dosage has been changed is not appropriate without verifying the correct dosage first.
B. Withholding the medication until the dosage can be confirmed is the safest approach to prevent potential medication errors.
C. Informing the client that he may refuse the medication is an option, but it does not address the potential discrepancy in dosage.
D. Telling him to take the medication and then verifying the dosage at the next healthcare team meeting could result in a medication error and is not a safe practice

A. Measure abdominal girth. B. Assess perineal area. C. Inspect the insertion site. D. Palpate flank area.

Correct Answer is C

Explanation

A. Measuring abdominal girth is not specific to suprapubic catheter care. While it may be relevant in certain situations, it does not directly assess the condition of the catheter or its insertion site.

B. Assessing the perineal area is important, but the primary focus for a client with a suprapubic catheter should be on the insertion site itself, as this is where complications such as infection or leakage are most likely to occur.

C. Assessing the insertion site is essential to monitor for any signs of infection, inflammation, or other complications related to the catheter. This assessment helps ensure the catheter is functioning correctly and that no adverse effects are developing.

D. Palpating the flank area is generally not a routine assessment for a client with a suprapubic catheter unless there are specific concerns about kidney function or pain in that area.
