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. When a nurse signs a consent form, which ethical principle is being observed regarding the patient?

• A. Autonomy
• B. Justice
• C. Accountability
• D. Beneficence

Correct answer: A

Rationale: The correct answer is 'Autonomy'. Autonomy refers to the patient's right to make their own decisions, which is being honored when a nurse signs a consent form. While beneficence (Choice D) is an important ethical principle that involves acting in the patient's best interest, it is not what is being primarily observed in this instance. Justice (Choice B) refers to fairness and equal treatment and is not specifically relevant to this scenario. Accountability (Choice C) pertains to being answerable for one's actions and decisions, but again, it is not the principle directly observed in this situation. Therefore, when a nurse signs a consent form, it is the principle of autonomy that is being observed.

3. Which foods are the biggest contributors of saturated fats consumed by Americans?

• A. Butter, coconut, and palm oils
• B. Corn oil
• C. Meat and milk
• D. Cheese, pizza, desserts, and chicken

Correct answer: D

Rationale: The correct answer is D: Cheese, pizza, desserts, and chicken. These foods are significant contributors to the intake of saturated fats in the American diet, often found in processed and fast foods. Choices A, B, and C are incorrect because while butter, coconut, and palm oils (A) are sources of saturated fats, they are not the biggest contributors in the American diet. Corn oil (B) is a source of unsaturated fats, and meat and milk (C) contain saturated fats but are not the primary contributors compared to cheese, pizza, desserts, and chicken.

4. Metabolic control is especially important for women with gestational diabetes to ensure the infant does not develop:

• A. microsomia
• B. macrosomia
• C. type 1 diabetes
• D. type 2 diabetes

Correct answer: B

Rationale: Metabolic control is crucial for women with gestational diabetes to prevent the development of macrosomia, which is characterized by an abnormally large baby. This condition poses risks such as birth injuries and necessitates careful management of blood sugar levels. Microsomia is not a known term related to this context. Type 1 and type 2 diabetes are not conditions the infant would develop as a result of gestational diabetes in the mother.

5. After cleaning the abrasions and applying antiseptic, the nurse applies a cold compress to the swollen ankle as ordered by the physician. This statement shows that the nurse has a correct understanding of the use of a cold compress:

• A. Cold compress reduces blood viscosity in the affected area
• B. It is safer to apply than a hot compress
• C. Cold compress prevents edema and reduces pain
• D. It eliminates toxic waste products due to vasodilation

Correct answer: C

Rationale: The correct understanding of using a cold compress includes knowing that it helps prevent edema and reduces pain. Cold application constricts blood vessels, reducing blood flow to the area, which helps decrease swelling and pain. Choices A, B, and D are incorrect because cold compresses do not directly affect blood viscosity, safety compared to hot compresses, or eliminate toxic waste products due to vasodilation. It is essential for nurses to have a clear understanding of the rationale behind interventions to provide effective patient care.
