1. Glucagon is a hormone released into the bloodstream in response to high blood sugar. It helps to lower blood glucose after a meal.
- A. TRUE
- B. FALSE
- C.
- D.
Correct answer: B
Rationale: Glucagon is released in response to low blood sugar and raises blood glucose levels by stimulating the release of glucose from liver stores, not lowering it.
2. 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.
3. A nurse is caring for an older adult client who reports difficulty chewing due to ill-fitting dentures. Which of the following foods should the nurse recommend for the client?
- A. Dried fruit
- B. Roast beef
- C. Tuna fish
- D. Apple slices
Correct answer: C
Rationale: The correct answer is C: Tuna fish. Tuna fish is a soft and easy-to-chew option, suitable for clients with ill-fitting dentures. Dried fruit (choice A) can be tough to chew and may stick to the dentures, causing discomfort. Roast beef (choice B) requires significant chewing effort and may not be suitable for someone with difficulty chewing. Apple slices (choice D) are crunchy and hard, which can be challenging for individuals with ill-fitting dentures.
4. A nurse is educating a group of older adults in a community center on weight management using the BMI scale. Using the client's height and weight to calculate BMI, which of the following clients has a healthy BMI?
- A. A client with a weight of 128 lb and height of 70 inches
- B. A client with a weight of 150 lb and height of 68 inches
- C. A client with a weight of 200 lb and height of 72 inches
- D. A client with a weight of 133 lb and height of 60 inches
Correct answer: A
Rationale: To determine a healthy BMI, we need to calculate it using the formula: BMI = weight (lbs) / height^2 (inches) x 703. For choice A, BMI = 128 / (70 x 70) x 703 = 18.38, which falls within the healthy BMI range of 18.5-24.9. Therefore, choice A is correct. Choices B, C, and D have BMIs of 22.8, 27.1, and 26.1, respectively, which are outside the healthy range. Thus, choices B, C, and D are incorrect.
5. Which is NOT a classification of carbohydrate?
- A. Monosaccharides
- B. Disaccharides
- C. Polysaccharides
- D. Triglycerides
Correct answer: D
Rationale: The correct answer is D, Triglycerides. Triglycerides are a type of fat, not a carbohydrate. Monosaccharides, disaccharides, and polysaccharides are all classifications of carbohydrates based on the number of sugar units they contain. Monosaccharides are the simplest form with one sugar unit, disaccharides contain two sugar units, and polysaccharides have multiple sugar units linked together.
