Nursing Elites

1. Which cells in the islet of the pancreas are responsible for synthesizing insulin?

• A. Alpha cells
• B. Beta cells
• C. Gamma cells
• D. Delta cells

Correct answer: B

Rationale: Beta cells in the islets of Langerhans in the pancreas are responsible for the production and secretion of insulin, which is crucial for regulating blood glucose levels. Alpha cells, on the other hand, produce glucagon, a hormone that raises blood glucose levels. Gamma cells and Delta cells do not exist in the islets of Langerhans; therefore, they are incorrect choices.

2. Which vitamin is crucial for collagen synthesis and wound healing?

• A. Vitamin C
• B. Vitamin D
• C. Vitamin E
• D. Vitamin K

Correct answer: A

Rationale: The correct answer is Vitamin C. Vitamin C is crucial for collagen synthesis, a process important for wound healing. Collagen is a key protein that helps in wound repair and tissue strength. Vitamin D is primarily known for its role in calcium absorption and bone health, not directly related to collagen synthesis. Vitamin E is an antioxidant that helps protect cells from damage but is not directly involved in collagen synthesis. Vitamin K is essential for blood clotting but does not play a major role in collagen synthesis for wound healing.

3. Which nursing diagnosis has nutritional implications?

• A. impaired dentition
• B. disruption of gas exchange
• C. self-esteem disturbance
• D. sleep pattern disturbance

Correct answer: A

Rationale: Impaired dentition affects a patient's ability to chew and consume a variety of foods, leading to potential nutritional deficiencies and malnutrition.

4. You are taking care of critically ill client and the doctor in charge calls to order a DNR (do not resuscitate) for the client. Which of the following is the appropriate action when getting DNR order over the phone?

• A. Have the registered nurse, family spokesperson, nurse supervisor and doctor sign
• B. Have 2 nurse validate the phone order, both nurses sign the order and the doctor should sign his order within 24
• C. Have the registered nurse, family and doctor sign the order
• D. Have 1 nurse take the order and sign it and have the doctor sign it within 24 hours

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

5. The purpose of the health history is to identify health-related considerations and medications that may cause nutritional risk. Many medications, such as prednisone, have drug-nutrient interactions that can influence nutrient needs.

• A. Both statements are true
• B. Both statements are false
• C. The first statement is true; the second is false
• D. The first statement is false; the second is true

Correct answer: A

Rationale: Both statements are true. The health history aims to uncover health-related factors that could pose nutritional risks, including medications like prednisone that may have interactions affecting nutrient requirements. Choice B is incorrect as both statements are accurate, emphasizing the significance of health history in assessing nutritional concerns.
