1. After a patient is exposed to a specific antigen, B cells will differentiate into:

• A. B cytotoxic cells
• B. Plasma cells
• C. Bursal cells
• D. Clonal equivalents

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.

2. A patient is prescribed medroxyprogesterone acetate (Provera) for endometriosis. What should the nurse teach the patient about the proper use of this medication?

• A. Take the medication at the same time each day to maintain consistent hormone levels.
• B. Avoid prolonged sun exposure while taking this medication.
• C. Discontinue the medication if side effects occur.
• D. Apply the medication once a week.

Correct answer: A

Rationale: The correct answer is to take the medication at the same time each day to maintain consistent hormone levels and effectiveness. Consistency in timing helps regulate the hormone levels in the body, ensuring the medication's optimal benefit. Choice B is incorrect as there is no specific need to avoid sun exposure with this medication. Choice C is incorrect because discontinuing the medication without consulting the healthcare provider may not be safe. Choice D is incorrect as medroxyprogesterone acetate is typically taken orally and not applied topically once a week.

3. When a Tae Kwon Do (TKD) master applies downward pressure just above the elbow joint on an attacker who immediately collapses to the ground, which reflex is applicable to this example?

• A. Golgi tendon reflex
• B. Myotatic reflex
• C. Withdrawal reflex
• D. Crossed-extensor reflex

Correct answer: A

Rationale: The Golgi tendon reflex is the correct answer. This reflex protects the muscle and tendons from excessive force by causing the muscle to relax. In this scenario, the downward pressure applied just above the elbow joint triggers the Golgi tendon reflex, resulting in the attacker's collapse. The other options are incorrect: - The myotatic reflex (also known as the stretch reflex) is responsible for contracting a muscle in response to its stretch, not relaxing it. - The withdrawal reflex is a spinal reflex that moves a body part away from a painful stimulus, not directly related to the scenario described. - The crossed-extensor reflex is a reflex that occurs on the opposite side of the body in response to a withdrawal reflex, which is not the case in this situation.

4. Which of the following is NOT an example of clinical manifestations of leukemia and lymphoma?

• A. Fatigue
• B. Increased risk of bleeding
• C. Increased risk of infections
• D. Increased energy and strength

Correct answer: D

Rationale: The correct answer is D: Increased energy and strength. Leukemia and lymphoma typically present with symptoms such as fatigue, weakness, increased risk of bleeding, and increased risk of infections. Patients with these conditions often experience a lack of energy and strength due to the disease's impact on the body. Therefore, increased energy and strength are not typical manifestations of leukemia and lymphoma.

5. A 52-year-old has made an appointment with his primary care provider and has reluctantly admitted that his primary health concern is erectile dysfunction (ED). He describes the problem as increasing in severity and consequent distress. Which of the nurse's assessment questions is most likely to address a common cause of ED?

• A. “How would you describe your overall health status?”
• B. “Are you taking any medications for high blood pressure?”
• C. “How has this issue been impacting your relationship?”
• D. “Have you experienced any recent injuries?”

Correct answer: B

Rationale: In the context of erectile dysfunction (ED), medication use is a crucial factor to consider. Many medications, including those used for high blood pressure, can contribute to ED as a side effect. Asking about medication use, particularly for conditions like high blood pressure, can help identify a common cause of ED. Choices A, C, and D do not directly address potential causes related to medication use, making them less likely to reveal a common underlying issue for ED in this case.
