1. Sildenafil (Viagra) is prescribed to treat a client with erectile dysfunction. A nurse reviews the client's medical record and would question the prescription if which of the following is noted in the client's history?

Correct answer: C

Rationale: The correct answer is C. Sildenafil (Viagra) enhances the vasodilating effect of nitric oxide and is contraindicated with the concurrent use of organic nitrates and nitroglycerin. Using nitroglycerin together with Viagra can lead to severe hypotension and cardiovascular collapse, making it unsafe to combine both medications.

2. When a client taking warfarin sodium (Coumadin) is prescribed ciprofloxacin (Cipro), the nurse should closely monitor the client for which potential effect of this drug interaction?

Correct answer: A

Rationale: When ciprofloxacin (Cipro) is given with warfarin sodium (Coumadin), it can potentiate the effects of warfarin, leading to an increased risk of bleeding. Therefore, the nurse should closely monitor the client's INR levels and watch for signs of bleeding such as bruising, petechiae, or black tarry stools.

3. A client with type 2 diabetes mellitus is prescribed metformin (Glucophage). Which instruction should the nurse include in the teaching plan?

Correct answer: C

Rationale: Clients taking metformin (Glucophage) should avoid alcohol as it can increase the risk of lactic acidosis. Metformin should be taken with meals to reduce gastrointestinal upset. While hypoglycemia is less common with metformin compared to other diabetes medications, clients should still be aware of its symptoms.

4. A client who has been newly diagnosed with diabetes mellitus has been stabilized with daily insulin injections. Which information should the nurse teach when carrying out plans for discharge?

Correct answer: B

Rationale: When a client is stabilized with daily insulin injections, it is crucial to rotate the injection sites systematically. This practice helps prevent the development of lipodystrophy, which can affect insulin absorption and lead to inconsistent glucose control. Additionally, rotating sites minimizes discomfort and tissue damage, ensuring optimal insulin delivery and effectiveness.

5. Alendronate (Fosamax) is prescribed for a client with osteoporosis. The client taking this medication is instructed to:

Correct answer: D

Rationale: Alendronate (Fosamax) should be taken with a full glass of water after rising in the morning to prevent gastrointestinal side effects and increase absorption. Taking the medication with a full glass of water and in an upright position after waking up helps decrease the risk of esophageal irritation and enhances the drug's effectiveness by ensuring proper absorption in the gastrointestinal tract.
