Pathophysiology Practice Exam Questions

Question 1 of 5

A patient with a history of cardiovascular disease is being prescribed hormone replacement therapy (HRT). What should the nurse include in the patient education regarding the risks associated with HRT?

Correct Answer: A

Rationale: The correct answer is A. Hormone replacement therapy (HRT) is associated with an increased risk of cardiovascular events, including heart attack and stroke, especially in patients with a history of cardiovascular disease. Choice B is incorrect because HRT does not decrease the risk of osteoporosis; in fact, it may increase the risk of certain conditions like venous thromboembolism, as mentioned in choice C. Choice D is also incorrect as HRT has been associated with a slight increase in the risk of breast cancer.

Question 2 of 5

How can a colony-stimulating factor affect the patient's erythrocyte count?

Correct Answer: A

Rationale: Colony-stimulating factors are substances that stimulate the production of blood cells in the bone marrow. Erythrocytes are red blood cells, so a colony-stimulating factor would specifically stimulate the growth of red blood cells, leading to an increase in the patient's erythrocyte count. Choice B is incorrect because colony-stimulating factors do not suppress T-cell production. Choice C is incorrect because colony-stimulating factors do not inhibit protein synthesis. Choice D is incorrect because colony-stimulating factors do not stimulate antibody production; they primarily affect the production of blood cells.

Question 3 of 5

A person is given an attenuated antigen as a vaccine. When the person asks what was given in the vaccine, how should the nurse respond? The antigen is:

Correct Answer: A

Rationale: An attenuated antigen used in a vaccine is alive but less infectious, aiming to stimulate an immune response. Choice B is incorrect because an attenuated antigen is not highly infectious. Choice C is incorrect as the antigen is intentionally altered to be less infectious. Choice D is incorrect as an attenuated antigen is not infectious.

Question 4 of 5

A male patient is concerned about the risk of prostate cancer while receiving finasteride (Proscar) for benign prostatic hyperplasia (BPH). What should the nurse explain about this risk?

Correct Answer: A

Rationale: The correct answer is A. Finasteride has been shown to lower the risk of developing prostate cancer. Studies have demonstrated that finasteride can reduce the incidence of prostate cancer. However, it is still recommended to have regular screening to monitor for any potential issues. Choice B is incorrect as finasteride has shown to have a positive effect on reducing prostate cancer risk. Choice C is inaccurate because finasteride decreases, not increases, the risk of prostate cancer. Choice D is incorrect as regular screening is still necessary despite the risk reduction associated with finasteride.

Question 5 of 5

A patient develops itching and burning of the vaginal vault while taking an anti-infective to treat strep throat. What fungal agent has most likely caused the burning and itching?

Correct Answer: B

Rationale: The correct answer is B: Candida albicans. Candida albicans is a common fungal agent responsible for causing vaginal yeast infections characterized by itching and burning. It is known to overgrow in the vagina, especially when the normal vaginal flora is disrupted, such as during antibiotic use. Cryptococcus neoformans is more associated with causing meningitis in immunocompromised individuals, not vaginal symptoms. Aspergillus is more commonly associated with lung infections and allergic reactions, not vaginal infections. Dermatophytes typically cause skin infections like ringworm, not vaginal symptoms.
