Nursing Elites

1. A patient is prescribed sildenafil (Viagra) for erectile dysfunction. What critical contraindication should the nurse review with the patient?

• A. Use of nitrates
• B. Use of antihypertensive medications
• C. History of hypertension
• D. History of peptic ulcer disease

Correct answer: A

Rationale: The correct answer is A: Use of nitrates. Sildenafil (Viagra) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates and sildenafil both cause vasodilation, which can lead to a dangerous drop in blood pressure. Choice B (Use of antihypertensive medications) is incorrect because antihypertensive medications are not a critical contraindication for sildenafil use. Choice C (History of hypertension) is incorrect as it is not a contraindication for sildenafil; in fact, sildenafil is sometimes used in patients with hypertension. Choice D (History of peptic ulcer disease) is also incorrect as it is not a critical contraindication for sildenafil use.

2. A patient has been prescribed raloxifene (Evista) for the prevention of osteoporosis. What effect should the nurse include in the teaching plan regarding the action of this medication?

• A. Decreases calcium excretion by the kidneys.
• B. Increases intestinal absorption of calcium.
• C. Stimulates bone formation by increasing osteoblast activity.
• D. Selectively binds to estrogen receptors, decreasing bone resorption.

Correct answer: D

Rationale: The correct answer is D: Selectively binds to estrogen receptors, decreasing bone resorption. Raloxifene is a selective estrogen receptor modulator (SERM) that works by binding to estrogen receptors, thereby decreasing bone resorption. This action helps in the prevention and treatment of osteoporosis by preserving bone density. Choices A, B, and C are incorrect because raloxifene does not directly affect calcium excretion by the kidneys, intestinal absorption of calcium, or stimulate bone formation by increasing osteoblast activity.

3. A patient is receiving chloroquine (Aralen) for extraintestinal amebiasis. Which of the following medications should be administered with chloroquine?

• A. Iodoquinol (Yodoxin)
• B. Metronidazole (Flagyl)
• C. Metyrosine (Demser)
• D. Carbamazepine (Tegretol)

Correct answer: B

Rationale: The correct answer is B: Metronidazole (Flagyl). When treating extraintestinal amebiasis, chloroquine is often used in combination with metronidazole to ensure the eradication of the parasite. Metronidazole helps to target the infection more effectively. Choices A, C, and D are incorrect. Iodoquinol (Yodoxin) is another antiprotozoal agent but is not typically used in combination with chloroquine for amebiasis. Metyrosine (Demser) is used in the management of pheochromocytoma, and carbamazepine (Tegretol) is an anticonvulsant and mood-stabilizing drug, neither of which are indicated for extraintestinal amebiasis.

4. What condition is a result of Polycythemia Vera, which involves excess red blood cells?

• A. Tissue ischemia & necrosis
• B. Chronic pancreatitis
• C. Low blood pressure & heart rate
• D. Increased numbers of infections

Correct answer: A

Rationale: Polycythemia Vera, characterized by excess red blood cells, can cause tissue ischemia and necrosis due to the increased blood viscosity. This condition restricts blood flow, leading to inadequate oxygen delivery to tissues and subsequent tissue damage. Choices B, C, and D are incorrect because they are not directly associated with the pathophysiology of Polycythemia Vera.

5. A patient is taking alendronate (Fosamax) for the treatment of osteoporosis. What instructions should the nurse provide to ensure the effectiveness of the medication?

• A. Take the medication with food to avoid gastrointestinal upset.
• B. Take the medication in the morning with a full glass of water and remain upright for at least 30 minutes.
• C. Take the medication before bed to ensure absorption during sleep.
• D. Take the medication with milk to enhance calcium absorption.

Correct answer: B

Rationale: The correct answer is B. Alendronate should be taken in the morning with a full glass of water and the patient should remain upright for at least 30 minutes. This is important to prevent esophageal irritation and ensure proper absorption of the medication. Choice A is incorrect because alendronate should not be taken with food as it can decrease its absorption. Choice C is incorrect as taking the medication before bed increases the risk of esophageal irritation and reduces absorption due to lying down. Choice D is also incorrect because taking alendronate with milk or other calcium-rich foods can decrease its absorption.
