A client with tuberculosis has been prescribed isoniazid and pyridoxine. Which adverse effects is the pyridoxine intended to prevent?

Discoloration of body fluids

Liver damage

Peripheral neuropathy

Drug-resistant tuberculosis .

Answer and Explanation

The Correct Answer is C

Choice A rationale
Pyridoxine, also known as vitamin B6, does not prevent discoloration of body fluids. This is not a known side effect of isoniazid.
Choice B rationale
While isoniazid can potentially cause liver damage, pyridoxine does not prevent this side effect. Instead, regular liver function tests are typically performed to monitor for this potential complication.
Choice C rationale
Pyridoxine is prescribed alongside isoniazid to prevent peripheral neuropathy, which is a potential side effect of isoniazid. Peripheral neuropathy can cause symptoms such as numbness and tingling in the hands and feet.
Choice D rationale
Pyridoxine does not prevent drug-resistant tuberculosis. Drug resistance is a complex issue that is not prevented by vitamin supplementation. Prednisone Prednisone Explore

Correct Answer is D

Explanation

Choice A rationale
While notifying the healthcare provider is an important step when an IV has infiltrated, it is not the immediate priority action.
Choice B rationale
Adding promethazine to the allergy list would not be appropriate unless the patient had an allergic reaction to the medication.
Choice C rationale
Continuing to monitor the site would not be the immediate priority action. The nurse should first stop the IV infusion to prevent further damage.
Choice D rationale
The nurse’s priority action should be to stop the IV infusion. This prevents further infiltration and potential tissue damage. After stopping the infusion, the nurse can then take further steps such as notifying the healthcare provider and assessing the patient’s condition.
