Question 1 of 5
The nurse is caring for a client receiving isoniazid (INH) for tuberculosis. Which instruction should the nurse include?
Correct Answer: C
Rationale: Isoniazid treats TB but risks hepatotoxicity, causing jaundice (yellowing skin, choice C), a serious sign needing immediate reporting to prevent liver failure. Food is optional'INH can be taken either way. Tyramine relates to MAOIs, not INH. Bedtime isn't specific'dosing is flexible. Reporting jaundice aligns with INH's side effect profile, critical in TB therapy where long-term use is common, making C the essential instruction for early detection and safety.

Question 3 of 5
Mannitol (Osmitrol), an osmotic diuretic, is contraindicated to which conditions? Select all that apply.
Correct Answer: B
Rationale: Mannitol is contraindicated in patients with narrow-angle glaucoma. It can exacerbate the condition by causing an increase in intraocular pressure, leading to potential vision damage or loss. Therefore, caution should be exercised and alternative treatments considered for patients with narrow-angle glaucoma when considering the use of mannitol.
Question 4 of 5
Which patient would benefit from administration of simvastatin (Zocor) 80 mg?
Correct Answer: D
Rationale: A patient who has already been taking simvastatin (Zocor) for 12 months with no evidence of myopathy would benefit from administration of simvastatin 80 mg. This is because patients who have been on a stable dose of simvastatin without experiencing muscle-related side effects are considered to be tolerating the medication well. Increasing the dose to 80 mg may provide additional benefits in terms of lowering cholesterol levels without significant risk of myopathy.
Question 5 of 5
A patient is being discharged on anticoagulant therapy. The nurse will include in the patient- education conversation that it is important to avoid herbal products that contain which substance?
Correct Answer: B
Rationale: Ginkgo is the herbal product to avoid because it can interact with anticoagulant therapy and increase the risk of bleeding. Ginkgo has blood-thinning properties, which can further potentiate the anticoagulant effects of medications like warfarin, increasing the risk of bleeding complications. It's essential for patients on anticoagulant therapy to avoid herbal products containing ginkgo to prevent adverse effects and ensure the effectiveness of their prescribed medication.
