1. What is responsible for initiating clonal selection?
- A. B cells
- B. T cells
- C. Antigens
- D. Lymphocytes
Correct answer: C
Rationale: Antigens are the correct answer as they are the molecules that trigger the immune response by binding to specific B or T cells. This binding activates these cells, leading to their proliferation and differentiation to fight off the antigen. B cells and T cells are the responders to antigens, not the initiators of clonal selection. Lymphocytes is a broad term encompassing both B and T cells, so it is not the specific factor responsible for initiating clonal selection.
2. Peritonitis is a condition that can result in serious complications. Identify one of the complications.
- A. Increased peristalsis
- B. Dizziness and malaise
- C. Sepsis and shock
- D. Nausea and vomiting
Correct answer: C
Rationale: Corrected Rationale: Peritonitis can lead to severe complications such as sepsis and shock due to the infection spreading in the abdominal cavity. Sepsis is a systemic inflammatory response to infection, and shock is a life-threatening condition where the body's organs are not receiving enough blood flow. Choices A, B, and D are incorrect. Increased peristalsis is not a typical complication of peritonitis; dizziness and malaise, as well as nausea and vomiting, are symptoms rather than complications of the condition.
3. Which statement best conveys an aspect of the role of cerebrospinal fluid (CSF)?
- A. CSF provides immune protection to the brain and spinal cord by serving as a physical barrier.
- B. CSF cushions the brain and spinal cord, protecting them from injury.
- C. CSF plays a limited role in the exchange of nutrients and waste products between the blood and brain.
- D. CSF functions primarily as a medium for the transmission of nerve impulses.
Correct answer: B
Rationale: The correct answer is B. Cerebrospinal fluid primarily cushions the brain and spinal cord, protecting them from injury. Choice A is incorrect because while CSF contributes to the brain's immune environment, its main role is not providing immune protection as a physical barrier. Choice C is incorrect because CSF has a significant role in the exchange of nutrients and waste products, rather than a limited one. Choice D is incorrect as CSF is not primarily a medium for nerve impulse transmission, but rather serves as a protective and supportive fluid.
4. What adverse effect should the nurse monitor for during testosterone therapy in a male patient?
- A. Increased risk of cardiovascular events
- B. Increased risk of liver dysfunction
- C. Increased risk of prostate cancer
- D. Increased risk of bone fractures
Correct answer: A
Rationale: The correct answer is A: Increased risk of cardiovascular events. Testosterone therapy can lead to an increased risk of cardiovascular events, such as heart attacks and strokes. This is why nurses should monitor for signs and symptoms of cardiovascular issues during therapy. Choices B, C, and D are incorrect because testosterone therapy is not typically associated with an increased risk of liver dysfunction, prostate cancer, or bone fractures. It is crucial for nurses to prioritize cardiovascular monitoring in patients receiving testosterone therapy.
5. A patient is taking medroxyprogesterone acetate (Provera) for the treatment of endometriosis. What should the nurse teach the patient about this medication?
- A. Medroxyprogesterone should be taken with food to prevent nausea.
- B. Medroxyprogesterone should be taken at the same time each day to maintain consistent hormone levels.
- C. Medroxyprogesterone can be taken intermittently when symptoms worsen.
- D. Medroxyprogesterone should be stopped if side effects occur.
Correct answer: B
Rationale: The correct answer is B. Medroxyprogesterone should be taken at the same time each day to maintain consistent hormone levels and effectiveness. Choice A is incorrect because medroxyprogesterone does not necessarily need to be taken with food. Choice C is incorrect as it is typically prescribed continuously rather than intermittently. Choice D is incorrect because patients should not stop the medication if side effects occur without consulting their healthcare provider.
