1. 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).

2. What is the purpose of the cuff in a Tracheostomy tube?

• A. Separate the upper and lower airway
• B. Separate trachea from the esophagus
• C. Separate the larynx from the nasopharynx
• D. Secure the placement of the tube

Correct answer: B

Rationale: The purpose of the cuff in a Tracheostomy tube is to separate the trachea from the esophagus. The cuff helps prevent aspiration by creating a seal that separates the trachea from the esophagus, reducing the risk of food or fluids entering the lungs. Choices A, C, and D are incorrect because the cuff's primary function in a Tracheostomy tube is to prevent aspiration rather than separating the upper and lower airway, larynx from the nasopharynx, or securing the placement of the tube.

3. 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.

4. Which factor contributes to the development of bone diseases in patients with Chronic Kidney Disease (CKD) due to retention?

• A. Iron
• B. Sodium
• C. Potassium
• D. Phosphorus

Correct answer: D

Rationale: The correct answer is phosphorus. Retention of phosphorus in patients with Chronic Kidney Disease (CKD) contributes to the development of bone disorders, including osteodystrophy, because it disrupts the balance of calcium and phosphorus in the body. This imbalance leads to a variety of bone diseases. The other options - iron, sodium, and potassium - while important in the overall metabolic function, are not directly linked to the development of bone diseases in CKD patients due to retention.

5. A nurse is providing nutritional information to a client with osteoporosis. Which food should the nurse recommend as being the highest in calcium?

• A. 1 cup carrot strips
• B. 3 oz canned salmon
• C. 1 plain baked potato
• D. 1 cup chopped chicken breast

Correct answer: B

Rationale: Canned salmon with bones is high in calcium.
