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 B

Explanation

Choice A reason: This is an incorrect action, because elevating the residual limb on a soft pillow can cause contractures and impair the blood flow to the stump. The residual limb should be elevated only for the first 24 hr after surgery, and then positioned flat on the bed.

Choice B reason: This is the correct action, because assisting the client to a prone position every 4 hr can prevent hip flexion contractures and promote the range of motion of the hip joint. The client should lie prone for 20 to 30 minutes at a time, with the residual limb extended.

Choice C reason: This is an incorrect action, because reapplying a bandage to the residual limb every 12 hr can increase the risk of infection and delay the healing of the wound. The bandage should be changed only when it is soiled or loose, and under sterile technique.

Choice D reason: This is an incorrect action, because applying dressings to the site in a proximal-to-distal direction can cause edema and impair the circulation to

A. Avoid IM injections. B. Obtain a rectal temperature once per shift. C. Do not allow the client to have visitors. D. Encourage daily flossing between teeth.

Correct Answer is A

Explanation

Choice A reason: This is the correct intervention, because avoiding IM injections can prevent bleeding and hematoma formation in the client who has low platelet count and impaired clotting.

Choice B reason: This is an incorrect intervention, because obtaining a rectal temperature once per shift can cause trauma and bleeding in the rectal mucosa, which is highly vascularized and sensitive.

Choice C reason: This is an unnecessary intervention, because the client who has thrombocytopenia does not have an increased risk of infection, unless they also have neutropenia or immunosuppression. The client should be allowed to have visitors, as long as they follow the infection control precautions.

Choice D reason: This is an incorrect intervention, because encouraging daily flossing between teeth can cause gingival bleeding and ulceration in the client who has low platelet count and impaired clotting. The client should use a soft toothbrush and avoid dental floss.
