Pathophysiology Exam 1 Quizlet

1. A nurse recalls an example of an immune-complex-mediated disease is:

Correct answer: C

Rationale: The correct answer is C: Serum sickness. Serum sickness is characterized by the formation of immune complexes in response to certain medications or proteins. These immune complexes can deposit in tissues, leading to inflammation and tissue damage. Bronchial asthma (Choice A) is a chronic inflammatory condition of the airways not primarily mediated by immune complexes. Contact dermatitis (Choice B) is a type IV hypersensitivity reaction mediated by T cells, not immune complexes. Rheumatoid arthritis (Choice D) is an autoimmune disease where antibodies target self-antigens, but it is not primarily mediated by immune complexes.

2. A woman has been prescribed Climara, a transdermal estradiol patch. Which of the following should she be instructed by the nurse regarding the administration?

Correct answer: A

Rationale: The correct answer is A. The Climara patch delivers estradiol transdermally, and patients should be instructed to avoid prolonged sun exposure at the patch site due to increased plasma concentrations. Sun exposure can accelerate the absorption of the medication, leading to higher systemic levels than intended. Choices B, C, and D are incorrect because heat at the patch site does not result in pregnancy but may alter absorption rates, there is no direct link between sunlight exposure and breast cancer risk related to this medication, and exposure to cold does not increase effectiveness of the transdermal patch.

3. Which individual is likely to have the best prognosis for recovery from his or her insult to the peripheral nervous system? An adult:

Correct answer: C

Rationale: The correct answer is C. Crushing-type injuries to the peripheral nervous system generally have a better prognosis compared to nerve transections or lacerations. In the scenario provided, the individual who had his forearm partially crushed by gears during an industrial accident is likely to have a better chance of recovery compared to nerve transection (choice D) or laceration (choice B). Rhabdomyolysis and ischemic injury after tourniquet application (choice A) are not directly related to peripheral nerve injury and do not indicate a better prognosis for recovery.

4. When discussing the risks associated with hormone replacement therapy (HRT) with a patient who has a history of coronary artery disease, what should the nurse emphasize?

Correct answer: A

Rationale: The correct answer is A. Hormone replacement therapy (HRT) is associated with an increased risk of cardiovascular events, such as heart attack and stroke, especially in patients with a history of coronary artery disease. Choice B is incorrect because HRT is actually known to decrease the risk of osteoporosis. Choice C is incorrect as HRT is associated with an increased risk of venous thromboembolism. Choice D is also incorrect as HRT may slightly increase the risk of breast cancer.

5. A nurse practitioner is assessing a 7-year-old boy who has been brought to the clinic by his mother, who is concerned about her son's increasingly frequent, severe headaches. Which of the nurse's questions is least likely to yield data that will confirm or rule out migraines as the cause of his problem?

Correct answer: C

Rationale: The correct answer is C. In assessing a child for migraines, asking about food allergies is least likely to yield data that will confirm or rule out migraines as the cause of his headaches. Food allergies are unrelated to the typical symptoms and triggers of migraines, such as family history, associated symptoms like nausea and vomiting, and pain-free intervals between headaches. Therefore, in this scenario, focusing on food allergies is less relevant for identifying migraines as the cause of the boy's headaches.
