Question

The nurse would expect the health care provider (HCP) to add which medication to the regimen of the client receiving isoniazid?

1) Niacin
2) Neurontin
3) Pyridoxine (vitamin B6)
4) Cyanocobalamin (vitamin B12)

Answer 1

Pyridoxine (vitamin B6) is commonly added to a regimen including isoniazid to prevent neurotoxic side effects caused by isoniazid's impact on vitamin B6 metabolism.

Step-by-step explanation:

The health care provider would most likely add Pyridoxine (vitamin B6) to the regimen of the client receiving isoniazid for the treatment of tuberculosis. Isoniazid is known to cause a deficiency in vitamin B6 due to its structural resemblance, leading to side effects such as neurotoxicity. Supplementation with pyridoxine is often recommended to prevent these side effects.

It is important to note that while isoniazid can also affect other vitamins such as niacin, the use of pyridoxine specifically addresses the significant risk of neurotoxic effects due to isoniazid's interference with vitamin B6 metabolism.
