Medical Surgical Tuberculosis #6

Question

Isoniazid is prescribed to a client with tuberculosis. How will the nurse instruct the client to take the medication?

Answers

  1. Take the medication with the evening meal for best absorption.
    • Rationale:

      This answer is not correct because taking Isoniazid with food will interfere with absorption of the medication. Compliance with the medication regimen used to treat tuberculosis is essential for proper treatment of the infection.

  2. Take the medication with antacids to relieve GI upset.
    • Rationale:

      This answer is not correct because antacids will interfere with absorption of the medication. Compliance with the medication regimen used to treat tuberculosis is essential for proper treatment of the infection.

  3. Take the medication 30 minutes following the first meal of the day.
    • Rationale:

      This answer is not correct because the medication should be taken at least 1 hour prior to or 2 hours after meals as food decreases absorption of Isoniazid.

  4. Take the medication on an empty stomach.
    • Rationale:

      This answer is correct because Isoniazid should be taken on an empty stomach. Food would interfere with absorption and antacids affect the medication (by decreasing its effectiveness) so the medication should be taken 1 hour prior to food or 2 hours following food intake.

Overview

The focus of this question is the appropriate client education regarding correct administration of isoniazid. The client should take this medication on an empty stomach to achieve maximum absorption of the medication.

Explanation

Learning Outcomes

Isoniazid is one of the medications that are typically used in combination to treat tuberculosis. Compliance with the medication regimen used to treat tuberculosis is essential for proper treatment of the infection. Clients should be educated on potential side effects and how to take each medication to facilitate compliance. Clients should be instructed to take isoniazid on an empty stomach because food interferes with the absorption of the medication.

Test Taking Tip

Look for answer choices that differ from the rest. Answer choice #4 is the only option that includes education to avoid taking Isoniazid with food.
