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. A nurse at a provider's office is providing teaching to a client who is taking chemotherapy and losing weight. Which of the following should the nurse recommend to increase calorie and protein intake? (Select one that does not apply.)

• A. Top yogurt with fruits.
• B. Add cream to soups.
• C. Use milk instead of water in recipes.
• D. Increase fluids during meals.

Correct answer: D

Rationale: The correct recommendation to increase calorie and protein intake for a client taking chemotherapy and losing weight is to add cream to soups (choice B), as it provides additional calories and proteins. Using milk instead of water in recipes (choice C) can also increase the calorie and protein content. Topping yogurt with fruits (choice A) can be a healthy choice but may not significantly increase calorie and protein intake. Increasing fluids during meals (choice D) may fill up the stomach, potentially reducing the intake of solid foods, which is not ideal when trying to increase calorie and protein consumption.

3. By the age of three, which age-appropriate food skill can a child typically perform?

• A. Using utensils and a napkin
• B. Spearing food with a fork
• C. Measuring liquids
• D. Displaying proper table manners

Correct answer: B

Rationale: By the age of three, a child typically develops the motor skills needed to spear food with a fork. This is a critical milestone in self-feeding as it shows progress in fine motor coordination. Choice 'A' is incorrect because using utensils and a napkin properly is a skill that may take longer to develop and refine. Choice 'C' is not correct as measuring liquids requires a higher level of motor skills and understanding of quantities that a three-year-old child might not possess. Choice 'D' is also incorrect as the proper display of table manners is a complex skill that is typically learned over a longer period and involves social and cultural norms.

4. Which is the priority nursing diagnosis for a patient with an indwelling urinary catheter?

• A. Self-esteem disturbance
• B. Impaired urinary elimination
• C. Impaired skin integrity
• D. Risk for infection

Correct answer: D

Rationale: The correct answer is 'D: Risk for infection.' An indwelling urinary catheter poses a significant risk for infection due to its invasive nature and the increased susceptibility to urinary tract infections. While 'B: Impaired urinary elimination' and 'C: Impaired skin integrity' may also be concerns for a patient with an indwelling urinary catheter, the immediate risk of infection is the priority. 'A: Self-esteem disturbance' is not typically a priority nursing diagnosis for a patient with an indwelling urinary catheter because the focus is primarily on infection prevention and management to ensure patient safety and well-being.

5. High intakes of which of the following interfere with copper absorption and can lead to a deficiency?

• A. chromium
• B. sodium
• C. zinc
• D. manganese

Correct answer: C

Rationale: The correct answer is C, zinc. High intakes of zinc can interfere with copper absorption, potentially leading to copper deficiency. Copper is essential for various bodily functions, including iron metabolism. Choice A, chromium, is incorrect because chromium does not interfere with copper absorption. Choice B, sodium, and Choice D, manganese, are also incorrect as they do not interfere with copper absorption.
