Nursing Elites

1. Which type of cells secrete insulin?

• A. alpha cells
• B. beta cells
• C. CD4 cells
• D. helper cells

Correct answer: B

Rationale: Beta cells are responsible for secreting insulin. Insulin is produced by beta cells in the pancreas and plays a crucial role in regulating blood sugar levels. Alpha cells secrete glucagon, not insulin (Choice A). CD4 cells are a type of immune cell that helps coordinate the immune response (Choice C). Helper cells are a type of immune cell that aids in activating other immune cells (Choice D). Therefore, the correct answer is beta cells.

2. A nurse is caring for a client with an elevated cortisol level. The nurse can expect the client to exhibit symptoms of:

• A. urinary excess
• B. hyperpituitarism
• C. urinary deficit
• D. hyperthyroidism

Correct answer: C

Rationale: Elevated cortisol levels can lead to sodium and fluid retention and potassium deficit, resulting in urinary deficit. This imbalance in electrolytes and fluid can cause a decrease in urinary output. Choices B, hyperpituitarism, and D, hyperthyroidism, are incorrect as they do not directly relate to the symptoms expected with elevated cortisol levels. Option A, urinary excess, is also incorrect as high cortisol levels typically lead to fluid retention and urinary deficit, not excess.

3. The client asked about the role of leptin in the body. Which response should the nurse provide?

• A. It increases food intake in clients, thereby promoting obesity.
• B. It assists in the regulation of steroids.
• C. It increases the total fat mass of people who are obese.
• D. It might decrease the total fat mass in the bodies of people who are obese.

Correct answer: D

Rationale: Leptin is a protein hormone expressed in fat cells that regulates fat cell percentage in the body. It is associated with increased energy expenditure and decreased food intake through hypothalamic control. In obese individuals, there may be insensitivity or resistance to leptin's effects. Leptin influences other hormones like insulin and genetic factors related to fat regulation. Therefore, the correct response is that leptin might decrease total fat mass in obese individuals as it is involved in energy balance and fat regulation. Choices A, B, and C are incorrect because leptin does not increase food intake or promote obesity; it does not assist in the regulation of steroids, and it does not increase total fat mass in people who are obese.

4. After experiencing a left frontal lobe CVA, a fifty-five-year-old man is being monitored by a nurse. The patient's family is not present in the room. What should the nurse observe most closely for?

• A. Changes in emotion and behavior
• B. Monitor loss of hearing
• C. Observe appetite and vision deficits
• D. Changes in facial muscle control

Correct answer: A

Rationale: The correct answer is to watch for changes in emotion and behavior. The frontal lobe, particularly the left side, is responsible for regulating behavior and emotions. Therefore, following a left frontal lobe CVA, monitoring for alterations in emotion and behavior is crucial. Choices B, C, and D are incorrect because loss of hearing, appetite and vision deficits, and changes in facial muscle control are not directly associated with a left frontal lobe CVA.

5. A client, age 28, was recently diagnosed with Hodgkin's disease. After staging, therapy is planned to include combination radiation therapy and systemic chemotherapy with MOPP"?nitrogen mustard, vincristine (Onconvin), prednisone, and procarbazine. In planning care for this client, the nurse should anticipate which of the following side effects to contribute to a sense of altered body image?

• A. Cushingoid appearance
• B. Alopecia
• C. Temporary or permanent sterility
• D. Pathologic fractures

Correct answer: B

Rationale: The correct answer is B: Alopecia. Chemotherapy drugs like vincristine can cause alopecia, which is hair loss. This side effect can significantly impact a patient's body image. While Cushingoid appearance (A) can be a side effect of long-term steroid use, temporary or permanent sterility (C) may affect a patient's future fertility but not necessarily alter body image. Pathologic fractures (D) are not common side effects of Hodgkin's disease or its treatment and do not directly contribute to a sense of altered body image in the same way as alopecia does.
