ATI Pathophysiology Exam 1

1. A patient with breast cancer is prescribed tamoxifen (Nolvadex). What key point should the nurse include in the patient education?

Correct answer: A

Rationale: The correct answer is A: "Tamoxifen may increase the risk of venous thromboembolism." It is crucial for patients to be aware of the signs and symptoms of blood clots while taking tamoxifen. Choice B is incorrect because hot flashes and menopausal symptoms are common side effects of tamoxifen, but they are not the key point to emphasize. Choice C is incorrect as weight gain and fluid retention are potential side effects of tamoxifen but not the key point for patient education. Choice D is incorrect as tamoxifen does not decrease the risk of osteoporosis; in fact, it may increase the risk of bone loss.

2. How can a nurse determine the efficacy of a child's mebendazole treatment for roundworm after 3 weeks?

Correct answer: B

Rationale: The correct answer is B: Stool for ova and parasites. To assess the efficacy of treatment for roundworm, the nurse would examine the stool for ova (eggs) and parasites. This test helps determine if the infection has been cleared. Choices A, C, and D are incorrect because liver function tests are not commonly used to monitor roundworm treatment efficacy, and colonoscopy/sigmoidoscopy as well as rectal swab for culture are not routine diagnostic tests for assessing the effectiveness of mebendazole treatment for roundworm.

3. When arterial blood pressure declines, the kidneys secrete a hormone to increase blood pressure and peripheral resistance. What is this hormone called?

Correct answer: A

Rationale: Renin is the correct answer. When arterial blood pressure decreases, the kidneys release renin, which triggers a series of reactions ultimately leading to an increase in blood pressure and peripheral resistance. Antidiuretic hormone (choice B) is involved in water retention, atrial natriuretic hormone (choice C) promotes sodium excretion and lowers blood pressure, and insulin (choice D) regulates glucose metabolism, not blood pressure.

4. Which of the following is the most likely indication for the use of immunosuppressant agents?

Correct answer: C

Rationale: The correct answer is C: Organ transplantation. Immunosuppressant agents are commonly used in organ transplant recipients to prevent organ rejection by suppressing the immune system. Choices A, B, and D are incorrect. Intractable seizure disorders are often managed with antiepileptic drugs, increased intracranial pressure is managed through various means like surgery and medications, and HIV/AIDS with multiple drug resistance is typically treated with antiretroviral therapy, not immunosuppressant agents.

5. When starting on oral contraceptives, what key point should the nurse emphasize about taking the medication consistently?

Correct answer: A

Rationale: When starting on oral contraceptives, it is crucial to take them at the same time each day to maintain stable hormone levels and ensure their effectiveness in preventing pregnancy. Choice B is incorrect because consistency in timing is essential to maximize contraceptive efficacy. Choice C is incorrect as there is no evidence that taking oral contraceptives in the morning helps avoid nighttime side effects. Choice D is incorrect because oral contraceptives do not provide immediate effectiveness and require consistent use to prevent pregnancy.
