Pathophysiology Exam 1 Quizlet

Correct Answer: C

Rationale: The correct answer is C: Changes in speech and reasoning. The frontal lobe is responsible for higher cognitive functions, including speech and reasoning. A lesion in this area can lead to difficulties in speech production, language comprehension, and reasoning abilities. Choices A, B, and D are incorrect. Changes in sensation or movement in the client's limbs are more associated with lesions in the motor or sensory cortices of the brain, not the frontal lobe. Fluctuations in blood pressure are often related to autonomic nervous system dysfunction, which is controlled by other brain regions. Increased intracranial pressure is typically seen in conditions like brain tumors or head trauma, not directly related to a frontal lobe lesion.

Correct Answer: A

Rationale: The correct answer is A. Tamoxifen increases the risk of venous thromboembolism. Patients should be educated about signs and symptoms of blood clots, such as swelling, pain, or redness in the legs. Choices B, C, and D are incorrect because tamoxifen is not associated with decreasing the risk of osteoporosis, causing hot flashes and menopausal symptoms, or causing weight gain and fluid retention.

Correct Answer: C

Rationale: Hypersensitivity is correctly defined as an excessive or inappropriate response of the immune system to a sensitizing antigen. This response leads to tissue damage or other clinical manifestations. Choice A is incorrect as hypersensitivity involves an exaggerated, not a reduced, immune response. Choice B is incorrect because hypersensitivity is not a normal immune response to an infectious agent but rather an exaggerated one. Choice D is incorrect as it refers to desensitization, which is the opposite of hypersensitivity.

Correct Answer: A

Rationale: The correct answer is A: "It inhibits bone resorption, which helps maintain bone density." Bisphosphonates work by inhibiting bone resorption carried out by osteoclasts, thereby preventing the breakdown of bones and helping to maintain or increase bone density in patients with osteoporosis. Choices B, C, and D are incorrect because bisphosphonates do not directly stimulate new bone formation, increase calcium absorption in the intestines, or decrease calcium excretion by the kidneys.

Correct Answer: C
