Pathophysiology Practice Questions

Correct Answer: C

Rationale: When dealing with an elderly client with Alzheimer's disease who is agitated and combative, the most appropriate nursing intervention is to remain calm and talk quietly to the client. This approach can help soothe the client and prevent escalating the situation. Choice A is incorrect as being firm may further agitate the client. Choice B is inappropriate as restraining should only be used as a last resort for safety reasons and after other de-escalation techniques have been attempted. Choice D is not the best initial intervention and should only be considered after other non-pharmacological interventions have failed.

Correct Answer: B

Rationale: The correct answer is B. Obesity and irregular menstrual cycles, including periods of amenorrhea and infrequent periods, are significant risk factors for the development of endometrial cancer. Choice A is less likely as postmenopausal status reduces the risk. Choice C is not directly associated with a high risk of endometrial cancer. Choice D, smoking, is more strongly linked to other types of cancers like lung cancer rather than endometrial cancer.

Correct Answer: B

Rationale: In peripheral artery disease, pain in the lower extremities worsens with the elevation of the extremity because it diverts blood flow away from the affected area, exacerbating the pain. Choices A, C, and D are incorrect. Resting doesn't increase blood flow, a dependent position doesn't lead to blood pooling in this context, and pain worsening due to touch or massage is not a typical feature of peripheral artery disease.

Correct Answer: A

Rationale: The correct answer is A: 'The hemorrhage will resolve without treatment within 2 weeks.' Subconjunctival hemorrhage typically resolves on its own without treatment. It is a self-limiting condition that does not require specific intervention. Choice B is incorrect as immediate ophthalmologic examination is not necessary for subconjunctival hemorrhage unless there are other concerning symptoms or risk factors present. Choice C is incorrect because corticosteroid eye drops are not typically used for subconjunctival hemorrhage. Choice D is also incorrect as antibiotic eye drops are not indicated since subconjunctival hemorrhage is not due to an infection.

Correct Answer: A

Rationale: The correct answer is A. Multiple sclerosis is characterized by the immune system attacking the myelin sheath in the central nervous system. This attack leads to patchy damage on the myelin sheath, resulting in asymmetrical neurological symptoms. Choices B, C, and D are incorrect because they do not accurately describe the pathophysiology of multiple sclerosis. In multiple sclerosis, it is the autoreactive lymphocytes that target and damage the myelin sheath, not acetylcholine receptors, T lymphocytes, or cortical motor cells.
