ATI Pathophysiology Exam 2

1. 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.

2. A patient is prescribed medroxyprogesterone acetate (Provera) for the treatment of endometriosis. What key instruction should the nurse provide regarding the administration of this medication?

Correct answer: A

Rationale: The correct instruction for medroxyprogesterone acetate (Provera) is to take the medication at the same time each day to maintain consistent hormone levels and ensure its effectiveness. Choice B is incorrect because discontinuing the medication abruptly without consulting healthcare providers can be harmful. Choice C is incorrect as taking the medication with food is not necessary for this specific drug. Choice D is incorrect as medroxyprogesterone is typically taken orally, not applied topically.

3. What is the primary role of albumin in the blood?

Correct answer: C

Rationale: The correct answer is C: Maintain osmotic pressure and fluid balance. Albumin plays a crucial role in maintaining osmotic pressure by helping to retain fluid within the blood vessels. This function is essential for regulating blood volume and preventing fluid from leaking out into tissues. Choices A, B, and D are incorrect because albumin is not primarily responsible for transporting oxygen, acting as a clotting factor, or functioning as an immune response molecule in the blood.

4. A patient is being educated about sildenafil (Viagra). Which of the following statements by the patient indicates that further teaching is necessary?

Correct answer: A

Rationale: The correct answer is A because sildenafil should not be taken with medications containing nitrates, such as nitroglycerin, due to the risk of severe hypotension. Choice B is incorrect because priapism (prolonged erection) is a serious side effect but does not require immediate intervention like severe hypotension. Choice C is incorrect as it correctly identifies a contraindication for sildenafil use. Choice D is incorrect because not all over-the-counter medications are safe to take with sildenafil, and interactions can occur.

5. A male patient is being treated with sildenafil (Viagra) for erectile dysfunction. What condition would contraindicate the use of this medication?

Correct answer: D

Rationale: The correct answer is D: Use of nitrates. Sildenafil (Viagra) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates and sildenafil both cause vasodilation, and the combination can lead to a dangerous drop in blood pressure. Choice A, peptic ulcer disease, is not a contraindication for sildenafil use. Choice B, a history of myocardial infarction, is not a contraindication unless the patient is also taking nitrates. Choice C, recent use of antihypertensive medications, is not a contraindication but requires caution as the combination can lead to additive effects lowering blood pressure.
