Nursing Elites

1. What causes atherosclerotic plaques to form initially?

• A. Interruption of blood flow to the brain
• B. Injury to the coronary artery endothelium
• C. Administration of statin medications
• D. Poor dietary modifications

Correct answer: B

Rationale: Atherosclerotic plaques form initially due to injury to the coronary artery endothelium, which triggers a cascade of events leading to plaque buildup. Choice A is incorrect because atherosclerotic plaques do not form due to an interruption of blood flow to the brain. Choice C is incorrect as statin medications are actually used to help lower cholesterol and reduce the risk of plaque formation. Choice D is incorrect as poor dietary modifications can contribute to atherosclerosis but are not the initial cause of plaque formation.

2. What critical point should the nurse include in patient education regarding tamoxifen (Nolvadex) for a patient with breast cancer?

• A. Tamoxifen may increase the risk of venous thromboembolism.
• B. Tamoxifen may cause hot flashes and other menopausal symptoms.
• C. Tamoxifen may cause weight gain and fluid retention.
• D. Tamoxifen may decrease the risk of osteoporosis.

Correct answer: A

Rationale: The correct answer is A. Tamoxifen increases the risk of venous thromboembolism. Patients should be educated about the signs and symptoms of blood clots, such as swelling, redness, and pain in the legs. Choices B, C, and D are incorrect because tamoxifen is not associated with causing hot flashes, weight gain, fluid retention, or decreasing the risk of osteoporosis.

3. A patient with endometriosis is prescribed medroxyprogesterone acetate (Provera). What should the nurse include in the patient education?

• A. Medroxyprogesterone should be taken at the same time each day to maintain consistent hormone levels.
• B. Medroxyprogesterone can be taken with food to reduce gastrointestinal upset.
• C. Medroxyprogesterone should be discontinued if side effects occur.
• D. Medroxyprogesterone should be taken once a week to maintain effectiveness.

Correct answer: A

Rationale: When educating a patient with endometriosis who is prescribed medroxyprogesterone acetate (Provera), the nurse should emphasize the importance of taking the medication at the same time each day. This helps maintain consistent hormone levels and ensures the effectiveness of the treatment. Option A is correct. Option B is incorrect because medroxyprogesterone should be taken consistently, regardless of food intake. Option C is incorrect because discontinuing the medication without consulting a healthcare provider can be harmful. Option D is incorrect because medroxyprogesterone is typically taken daily, not weekly, for the treatment of endometriosis.

4. A patient is being treated for active tuberculosis with ethambutol (Myambutol). The patient states to the nurse that he cannot identify the red and green on the traffic lights when he is driving. Based on this finding, what medical intervention is most appropriate?

• A. Assess for photosensitivity.
• B. Discontinue ethambutol (Myambutol).
• C. Decrease the ethambutol (Myambutol) dose.
• D. Administer vitamin B.

Correct answer: A

Rationale: The correct answer is to assess for photosensitivity. Ethambutol can cause optic neuritis, leading to visual disturbances, including difficulty differentiating red and green colors. This is a sign of optic nerve damage and requires immediate evaluation. Discontinuing ethambutol may be necessary if optic neuritis is confirmed, but this decision should be made by a healthcare provider. Decreasing the dose of ethambutol may not address the visual changes. Administering vitamin B does not directly address the side effect caused by ethambutol.

5. A patient with a history of osteoporosis is prescribed alendronate (Fosamax). What instructions should the nurse provide to ensure the effectiveness of the medication?

• A. Take the medication with a full glass of water and remain upright for at least 30 minutes to prevent esophageal irritation and ensure proper absorption.
• B. Take the medication with milk to enhance calcium absorption.
• C. Take the medication at bedtime to ensure absorption during sleep.
• D. Take the medication with food to prevent nausea.

Correct answer: A

Rationale: The correct answer is A. Alendronate should be taken with a full glass of water and patients should remain upright for at least 30 minutes to prevent esophageal irritation and ensure proper absorption. Taking the medication with milk (choice B) is not recommended as it may interfere with the absorption of alendronate. Taking the medication at bedtime (choice C) is not necessary for optimal absorption. Taking the medication with food (choice D) is also not recommended as food can reduce the absorption of alendronate.
