ATI Pathophysiology Exam 2 Questions
Question 1 of 5
After a patient is exposed to a specific antigen, B cells will differentiate into:
Correct Answer: B
Rationale: After exposure to a specific antigen, B cells undergo differentiation into plasma cells. Plasma cells are responsible for producing antibodies in response to the antigen. Choice A ('B cytotoxic cells') is incorrect because B cells do not differentiate into cytotoxic cells; cytotoxic cells are typically associated with T cells. Choice C ('Bursal cells') is incorrect as bursal cells are specific to birds and not relevant to human immune responses. Choice D ('Clonal equivalents') is incorrect as it does not describe the differentiation process of B cells exposed to antigens.
Question 2 of 5
After teaching the students about B cells, which statement indicates teaching was successful? B cells are originally derived from cells of the:
Correct Answer: A
Rationale: The correct answer is A: Bone marrow. B cells are originally derived from cells of the bone marrow. Bone marrow is the primary site where B cells develop and mature. Lymph nodes (choice B), gut-associated lymphoid tissue (choice C), and the thymus (choice D) are involved in the immune response but are not the primary site of origin for B cells.
Question 3 of 5
A 22-year-old was recently diagnosed with acquired immunodeficiency syndrome (AIDS). Which decreased lab finding would be expected to accompany this virus?
Correct Answer: A
Rationale: In a person diagnosed with AIDS, a decrease in CD4 helper T cells is expected. These cells are critical for the immune system's proper functioning, and their reduction weakens the body's ability to fight infections. CD8 helper T cells (Choice B) are not typically decreased in AIDS. CDC cells (Choice C) and CDC10 cells (Choice D) are not relevant terms in this context, making them incorrect choices.
Question 4 of 5
When teaching a young woman about the use of hormonal contraceptives, a nurse should emphasize that these drugs are most effective when taken:
Correct Answer: B
Rationale: The correct answer is B: 'At the same time each day.' Hormonal contraceptives should be taken consistently at the same time each day to maintain stable hormone levels, which is crucial for their effectiveness. Taking them at random times can increase the risk of contraceptive failure. Choices A, C, and D are incorrect because taking hormonal contraceptives immediately after sexual intercourse, before going to bed at night, or on an empty stomach does not align with the recommended usage instructions for these drugs.
Question 5 of 5
A patient has been prescribed conjugated estrogens for the treatment of menopausal symptoms. What should the nurse include in the patient teaching?
Correct Answer: A
Rationale: The correct answer is A: Increase the intake of calcium-rich foods. Patients taking conjugated estrogens should increase their intake of calcium-rich foods to help prevent osteoporosis. Estrogen therapy can lead to an increased risk of osteoporosis, so ensuring an adequate intake of calcium is crucial. Choices B, decreasing high-fat foods, and C, avoiding tobacco, are general health recommendations but not directly related to the prescription of conjugated estrogens. Choice D, avoiding exposure to sunlight, is not a direct concern when taking conjugated estrogens.
