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. Select all that apply. A person who is deficient in vitamin A could consume which of the following to increase vitamin A levels?

• A. cantaloupe
• B. eggs
• C. carrots
• D. all of the above

Correct answer: D

Rationale: Vitamin A can be found in high amounts in foods like cantaloupe, eggs, carrots, and milk, all of which help to maintain healthy vision, skin, and immune function.

3. A client with Crohn's disease is being cared for by a nurse. Which of the following food choices aligns with the recommended diet for clients with Crohn's disease?

• A. Vanilla milkshake
• B. Buttered popcorn
• C. Tossed green salad
• D. Toast with jelly

Correct answer: C

Rationale: The correct answer is a 'Tossed green salad.' Clients with Crohn's disease often benefit from a low-residue diet, which includes easily digestible foods like leafy green vegetables found in a tossed green salad. This type of diet helps minimize gastrointestinal symptoms. Choices A, B, and D are not ideal for clients with Crohn's disease. Vanilla milkshake, buttered popcorn, and toast with jelly may exacerbate symptoms due to their high fat, fiber, or sugar content, which can be harder to digest.

4. What is the approximate energy value of alcohol?

• A. 3 kcal/g
• B. 7 kcal/g
• C. 10 kcal/g
• D. 25 kcal/g

Correct answer: B

Rationale: The correct answer is B: 7 kcal/g. Alcohol provides approximately 7 kilocalories per gram, making it a significant source of energy or 'empty calories' in the diet that do not contain any nutrients. 'Empty calories' refer to the calorie content without the presence of essential nutrients. Choices A, C, and D are incorrect. The energy values of 3 kcal/g, 10 kcal/g, and 25 kcal/g are not accurate for alcohol; instead, they may pertain to other nutrients such as carbohydrates (approximately 4 kcal/g), fats (approximately 9 kcal/g), and oils (approximately 9 kcal/g).

5. You will do nasopharyngeal suctioning on Mr. Abad. Your guide for the length of insertion of the tubing for an adult would be:

• A. tip of the nose to the base of the neck
• B. the distance from the tip of the nose to the middle of the neck
• C. the distance from the tip of the nose to the tip of the ear lobe
• D. eight to ten inches

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
