1. Where does carbohydrate digestion begin?
- A. Mouth
- B. Esophagus
- C. Stomach
- D. Small intestine
Correct answer: A
Rationale: Carbohydrate digestion begins in the mouth. The enzyme amylase, found in saliva, starts the process by breaking down starches into sugars. The esophagus is a passageway for food to reach the stomach and does not participate in digestion. The stomach mainly digests proteins and is not the primary site for carbohydrate breakdown. While the small intestine does play a crucial role in digesting carbohydrates, it is not where the process initiates. Therefore, the correct answer is the mouth.
2. What is the role of fat in digestion?
- A. Digest fats in the stomach
- B. Emulsify fats in the small intestine
- C. Transport fats through the circulatory system
- D. Split fats into smaller components
Correct answer: B
Rationale: The correct answer is B: Emulsify fats in the small intestine. Bile emulsifies fats in the small intestine, breaking them down into smaller droplets that can be more easily digested by enzymes like lipase. Choice A is incorrect as fats are not digested in the stomach but rather in the small intestine. Choice C is incorrect as fats are transported through the lymphatic system instead of the circulatory system. Choice D is incorrect as fats are broken down into smaller components through emulsification, not splitting.
3. Which vitamin acts most like a hormone?
- A. Vitamin A
- B. Vitamin B
- C. Vitamin D
- D. Vitamin C
Correct answer: C
Rationale: The correct answer is Vitamin D. Although vitamin D, also known as calciferol, has been called a vitamin, it is more appropriately classified as a hormone. Like hormones, vitamin D acts to control the function of other cell types. For example, it helps the body absorb and regulate skeletal calcium and phosphorus levels. Choice A (Vitamin A) plays a crucial role in vision and immune function. Choice B (Vitamin B) is a complex of different vitamins that play various roles in the body. Choice D (Vitamin C) is important for collagen production and acts as an antioxidant.
4. How many calories are contained in a food that has 15 grams of carbohydrates, 4 grams of protein, and 10 grams of fat?
- A. 106
- B. 124
- C. 166
- D. 202
Correct answer: C
Rationale: To calculate the total calories in a food item, you can use the following conversions: every 1 gram of carbohydrate provides 4 calories, 1 gram of protein provides 4 calories, and 1 gram of fat provides 9 calories. Therefore, for this food item, multiply 15 grams of carbohydrates by 4 calories/gram, 4 grams of protein by 4 calories/gram, and 10 grams of fat by 9 calories/gram. The calculation would be (15 * 4) + (4 * 4) + (10 * 9) = 60 + 16 + 90 = 166 calories. Choice A (106) is incorrect because it does not consider the calories from fat. Choice B (124) is incorrect as it underestimates the calories by not including all macronutrients. Choice D (202) is incorrect as it overestimates the calories by adding up the values incorrectly.
5. Most nurses regard this conventional recording of the date, time, and mode by which the patient leaves a healthcare unit but this record includes importantly, directs of planning for discharge that starts soon after the person is admitted to a healthcare institution. It is accepted that collaboration or multidisciplinary involvement (of all members of the health team) in discharge results in comprehensive care. What do you call this?
- A. Discharge Summary
- B. Nursing Kardex
- C. Medicine and Treatment Record
- D. Nursing Health History and Assessment Worksheet
Correct answer: C
Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
