A nurse is reinforcing teaching with a client who has tuberculosis (TB) and a prescription for isoniazid. Which of the following instructions should the nurse include?

It is necessary to take this medication for the rest of your life to prevent recurrence.

Your provider will monitor your liver function while you are taking this medication.

Limit your alcohol intake to 2 drinks per day.

It is recommended to take this medication with a meal to increase absorption.

Answer and Explanation

The Correct Answer is B

Choice A reason: This is an incorrect instruction, because it is not necessary to take this medication for the rest of your life to prevent recurrence. Isoniazid is usually taken for 6 to 9 months, or as prescribed by the provider, to treat active TB or latent TB infection.

Choice B reason: This is the correct instruction, because your provider will monitor your liver function while you are taking this medication. Isoniazid can cause hepatotoxicity, which is a serious side effect that can damage the liver and cause jaundice, nausea, vomiting, or abdominal pain.

Choice C reason: This is an incorrect instruction, because you should avoid alcohol intake while you are taking this medication. Alcohol can increase the risk of hepatotoxicity and interfere with the metabolism of isoniazid.

Choice D reason: This is an incorrect instruction, because it is not recommended to take this medication with a meal to increase absorption. Isoniazid should be taken on an empty stomach, at least 1 hour before or 2 hours after a meal, to ensure optimal absorption and effectiveness.

Correct Answer is C

Explanation

Choice A reason: This is a correct statement, because using a soft toothbrush or foam swab for oral care can help prevent trauma and irritation to the mucous membranes of the mouth, which are inflamed and ulcerated due to stomatitis. The client should brush the teeth gently and avoid using dental floss.

Choice B reason: This is an incorrect statement, because using an alcohol-based mouthwash can cause burning, drying, and further damage to the mucous membranes of the mouth, which are already compromised by stomatitis. The client should avoid using any mouthwash that contains alcohol, menthol, or other harsh ingredients.

Choice C reason: This is a correct statement, because using a straw when drinking liquids can help reduce the contact and friction of the fluids with the mouth sores, which can cause pain and discomfort. The client should drink plenty of fluids to prevent dehydration and maintain hydration.

Choice D reason: This is a correct statement, because rinsing the mouth frequently with a hydrogen peroxide solution can help cleanse and disinfect the mouth, and promote healing of the mouth sores. The client should dilute the hydrogen peroxide with water and rinse the mouth at least four times a day, or as prescribed by the provider.

A. Irrigate the catheter with sterile water B. Clamp the drainage catheter during ambulation C. Report viscous drainage with clots to the provider D. Remove the catheter if the client feels a strong urge to urinate

Correct Answer is C

Explanation

Choice A reason: Irrigating the catheter with sterile water is an incorrect action, because the catheter should be irrigated with sterile normal saline (0.9% sodium chloride) to prevent hemolysis of the red blood cells.

Choice B reason: Clamping the drainage catheter during ambulation is an incorrect action, because the catheter should be kept patent and unclamped at all times to prevent obstruction and infection.

Choice C reason: Reporting viscous drainage with clots to the provider is a correct action, because it indicates that the irrigation is not effective and the client may need manual irrigation or surgical intervention.

Choice D reason: Removing the catheter if the client feels a strong urge to urinate is an incorrect action, because the catheter should be left in place until the provider orders its removal. The client may feel a sensation of bladder fullness or spasms due to the irrigation fluid, which can be relieved by medication or adjustment of the flow rate.
