Nursing Elites

1. Hematopoiesis occurs primarily in the bone marrow. What cells are formed during this process?

• A. Pancreatic beta cells
• B. Red blood cells
• C. Gastric parietal cells
• D. Neurons and glial cells

Correct answer: B

Rationale: The correct answer is B: Red blood cells. Hematopoiesis is the process of blood cell formation that primarily occurs in the bone marrow. Red blood cells are one of the main cell types formed during this process. Pancreatic beta cells (Choice A), gastric parietal cells (Choice C), and neurons and glial cells (Choice D) are not formed during hematopoiesis. Pancreatic beta cells are involved in insulin production, gastric parietal cells secrete gastric acid, and neurons and glial cells are part of the nervous system.

2. Nurse Isabelle enters the room of a client with a cognitive impairment disorder and asks what day of the week it is, what the date, month, and year are, and where the client is. The nurse is attempting to assess:

• A. confabulation.
• B. delirium.
• C. orientation.
• D. perseveration.

Correct answer: C

Rationale: The correct answer is C: "orientation." Nurse Isabelle is assessing the client's orientation by asking questions about time (day, date, month, year), place, and person. This assessment helps determine the client's awareness of their surroundings and situation. Confabulation (choice A) is the unintentional fabrication of details or events to fill in memory gaps and is not being assessed in this scenario. Delirium (choice B) is a state of acute confusion and disorientation, usually with a rapid onset, which is different from assessing orientation. Perseveration (choice D) refers to the persistent repetition of a response, statement, or behavior and is not the focus of the assessment being conducted by Nurse Isabelle in this situation.

3. Which of the following is a cause of edema?

• A. Decreased plasma proteins
• B. Hypotension
• C. Dehydration
• D. Polyuria

Correct answer: A

Rationale: The correct answer is A: Decreased plasma proteins. Edema can be caused by decreased plasma proteins, which reduce the osmotic pressure that keeps fluid in the blood vessels. Hypotension (choice B) is low blood pressure and is not a direct cause of edema. Dehydration (choice C) involves a lack of body fluid, but it is not a direct cause of edema. Polyuria (choice D) is excessive urination and not a direct cause of edema.

4. A patient with a history of venous thromboembolism is prescribed hormone replacement therapy (HRT). What should the nurse emphasize about the risks associated with this therapy?

• A. HRT is associated with an increased risk of venous thromboembolism, so patients should be educated about the signs and symptoms of blood clots.
• B. HRT may improve mood and energy levels, but it also increases the risk of osteoporosis.
• C. HRT can decrease the risk of fractures, but it also increases the risk of developing diabetes.
• D. HRT may increase the risk of breast cancer, so regular mammograms are essential.

Correct answer: A

Rationale: HRT is associated with an increased risk of venous thromboembolism, so patients should be educated about the signs and symptoms of blood clots and advised to seek immediate medical attention if they occur.

5. 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.
