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 older age and the use of certain medications can increase the risk of developing drug- resistant tuberculosis, these factors alone do not pose the greatest risk.
Choice B rationale
The presence of a red-orange color in the urine after being treated with rifampin is a common side effect of the medication and does not indicate an increased risk of developing drug- resistant tuberculosis.
Choice C rationale
A patient who has been taking rifampin and isoniazid as prescribed for 24 months is not at the greatest risk of developing drug-resistant tuberculosis. Adherence to the prescribed treatment regimen is actually crucial in preventing the development of drug-resistant strains of the disease.
Choice D rationale
A patient who did not complete the full course of anti-tubercular therapy in the past is at the greatest risk of developing a drug-resistant form of the disease. Incomplete treatment can allow tuberculosis bacteria to develop resistance to the medications used, leading to the emergence of drug-resistant strains.

A. 4.5 units B. 5.7 units C. 6.2 units D. 7.1 units

Correct Answer is B

Explanation

Choice A rationale
This choice suggests that the nurse would administer 4.5 units of insulin for the carbohydrates consumed. However, this is not accurate. The carbohydrate ratio is 1:10, meaning 1 unit of insulin is needed for every 10 grams of carbohydrates. The client consumed 57 grams of carbohydrates (45g from rice + 12g from broccoli). Therefore, the calculation would be 57g ÷ 10 = 5.7 units of insulin. This choice underestimates the amount of insulin needed, which could lead to hyperglycemia, or high blood sugar.
Choice B rationale
This choice is correct. The client’s carbohydrate ratio is 1:10, meaning 1 unit of insulin is needed for every 10 grams of carbohydrates. The client consumed 57 grams of carbohydrates (45g from rice + 12g from broccoli). Therefore, the calculation would be 57g ÷ 10 = 5.7 units of insulin. This amount of insulin would help to properly metabolize the carbohydrates consumed and maintain the client’s blood sugar within the target range.
Choice C rationale
This choice suggests that the nurse would administer 6.2 units of insulin for the carbohydrates consumed. However, this is not accurate. The carbohydrate ratio is 1:10, meaning 1 unit of insulin is needed for every 10 grams of carbohydrates. The client consumed 57 grams of carbohydrates (45g from rice + 12g from broccoli). Therefore, the calculation would be 57g ÷ 10 = 5.7 units of insulin. This choice overestimates the amount of insulin needed, which could lead to hypoglycemia, or low blood sugar.
Choice D rationale
This choice suggests that the nurse would administer 7.1 units of insulin for the carbohydrates consumed. However, this is not accurate. The carbohydrate ratio is 1:10, meaning 1 unit of insulin is needed for every 10 grams of carbohydrates. The client consumed 57 grams of carbohydrates (45g from rice + 12g from broccoli). Therefore, the calculation would be 57g ÷ 10 = 5.7 units of insulin. This choice significantly overestimates the amount of insulin needed, which could lead to hypoglycemia, or low blood sugar.
