A client with tuberculosis has been prescribed isoniazid and pyridoxine. Which adverse effects is the pyridoxine intended to prevent?
Correct answer
C
Rationale
The correct answer is C: Peripheral neuropathy. Pyridoxine, also known as vitamin B6, is prescribed along with isoniazid to prevent the development of peripheral neuropathy, a common adverse effect of isoniazid. Isoniazid can lead to a deficiency of vitamin B6 in the body, resulting in nerve damage. Pyridoxine supplementation helps counteract this deficiency and reduces the risk of peripheral neuropathy.
Choices A, B, and D are incorrect. Choice A, discoloration of body fluids, is not a known adverse effect of isoniazid or pyridoxine. Choice B, liver damage, is a potential adverse effect of isoniazid but is not the specific adverse effect that pyridoxine is intended to prevent. Choice D, drug-resistant tuberculosis, is not an adverse effect of either medication but rather a consequence of inappropriate or incomplete treatment.
