Question 1 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 2 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 3 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.
Question 4 of 5
A patient with a new prescription for a HMG-CoA (statin) drug is instructed to take the
Correct Answer: D
Rationale: The best response among the options provided is "This timeframe correlates better with the natural diurnal rhythm of cholesterol production." Statins work by inhibiting HMG-CoA reductase, an enzyme responsible for cholesterol production in the liver. Cholesterol synthesis follows a diurnal rhythm, with higher levels produced at night.
Therefore, taking a statin medication in the evening aligns with the body's natural pattern of cholesterol synthesis, optimizing the drug's effectiveness. This explanation helps the patient understand the rationale behind the timing of taking the medication and promotes better adherence to the prescribed regimen.
Question 5 of 5
When administering heparin subcutaneously, the nurse will follow which procedure?
Correct Answer: D
Rationale: When administering heparin subcutaneously, the nurse should use a - to -inch, 25- to 30-gauge needle to inject the medication into the subcutaneous tissue. This needle size is appropriate for delivering the medication effectively and safely in the subcutaneous layer rather than deeper into the muscle. Using the correct needle size helps ensure proper absorption and reduces the risk of complications such as bleeding or bruising at the injection site.
