MSN 570 Advanced Pathophysiology Final 2024
1. A 30-year-old man has a history of heart transplant and is receiving long-term steroids to prevent rejection. The patient is due for routine vaccines. Attenuated vaccines are contraindicated in this patient because the antigen is:
- A. live and can cause infection.
- B. mutated and infectious.
- C. inactive but still infectious
- D. pathogenic
Correct answer: A
Rationale: The correct answer is A: live and can cause infection. Patients who are immunocompromised, like those receiving long-term steroids after an organ transplant, should not receive live vaccines because the live attenuated organisms in these vaccines can cause infections in individuals with weakened immune systems. Choice B is incorrect because attenuated vaccines are live but weakened, not mutated. Choice C is incorrect because while inactive, attenuated vaccines are not infectious. Choice D is incorrect because attenuated vaccines are not pathogenic; they are attenuated (weakened) forms of the pathogen.
2. A client is admitted with a suspected aortic dissection. What is the priority nursing intervention?
- A. Administer antihypertensive medications as prescribed.
- B. Prepare the client for emergency surgery.
- C. Administer intravenous fluids to maintain blood pressure.
- D. Monitor the client's urine output closely.
Correct answer: B
Rationale: The correct answer is B: Prepare the client for emergency surgery. Aortic dissection is a life-threatening emergency that often necessitates immediate surgical intervention to prevent rupture and further complications. Administering antihypertensive medications (choice A) may be necessary but is not the priority over surgical intervention. While maintaining blood pressure with intravenous fluids (choice C) is important, the urgent need for surgery takes precedence. Monitoring urine output (choice D) is essential for assessing renal function but is not the priority in this critical situation.
3. 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.
4. In menopausal women, what is the primary goal of estrogen therapy?
- A. To relieve menopausal symptoms
- B. To prevent osteoporosis
- C. To increase calcium absorption
- D. To maintain bone strength
Correct answer: B
Rationale: The primary goal of estrogen therapy in menopausal women is to prevent osteoporosis by maintaining bone density. Estrogen helps in preserving bone mass and reducing the risk of fractures. While estrogen therapy may alleviate some menopausal symptoms, such as hot flashes, its primary focus is on bone health rather than symptom management. Increasing calcium absorption and maintaining bone strength are outcomes of preventing osteoporosis rather than the primary goal of estrogen therapy.
5. What is the primary function of the kidneys in acid-base balance?
- A. The kidneys remove hydrogen ions and retain bicarbonate ions.
- B. The kidneys convert ammonia into urea, which is excreted in the urine.
- C. The kidneys produce aldosterone to regulate sodium levels.
- D. The kidneys secrete renin to regulate blood pressure.
Correct answer: A
Rationale: The correct answer is A. The kidneys are crucial in maintaining acid-base balance by removing hydrogen ions to decrease acidity and retaining bicarbonate ions to increase alkalinity. Choice B is incorrect because the conversion of ammonia into urea is related to nitrogen waste excretion, not acid-base balance. Choice C is incorrect as aldosterone regulates sodium levels, not acid-base balance. Choice D is also incorrect as renin is involved in regulating blood pressure, not acid-base balance.
