Nursing Elites

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. A client with hypertension is being educated by a nurse about a heart-healthy diet. Which of the following statements indicates that the client understands the teaching?

• A. I will get 15% of my total daily calories from saturated fats.
• B. I will decrease the potassium in my diet.
• C. I will limit my daily sodium intake to 3 grams.
• D. I will eat five 8-ounce servings of fruit daily.

Correct answer: C

Rationale: The correct answer is C. Limiting daily sodium intake to 3 grams is crucial in managing blood pressure and is a fundamental aspect of a heart-healthy diet. High sodium intake can contribute to hypertension and cardiovascular issues. Choices A, B, and D are incorrect because getting 15% of daily calories from saturated fats, decreasing potassium intake, and eating five servings of fruit do not directly address the management of hypertension through sodium restriction.

3. During operation, who manages the lighting, noise, temperature and other factors in the operating room suite?

• A. Nurse Supervisor
• B. Surgeon
• C. Circulating Nurse
• D. Scrub Nurse

Correct answer: C

Rationale: In an operating room, the circulating nurse is responsible for managing environmental factors such as lighting, noise, and temperature. This role includes ensuring the comfort and safety of the patient, as well as the efficiency of the team. While the Nurse Supervisor, Surgeon, and Scrub Nurse also have crucial roles during an operation, they do not directly manage the environmental conditions of the operating room. The rationale provided does not directly address the question asked, and appears to relate more to the broader role of nursing in patient care.

4. Each of the following is a fat-soluble vitamin except for one. Which is the exception?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin K

Correct answer: B

Rationale: The correct answer is B, Vitamin C. Vitamin C is a water-soluble vitamin, not fat-soluble. Fat-soluble vitamins are Vitamins A, D, E, and K. These vitamins are stored in the body's fat tissues and liver, unlike water-soluble vitamins which are not stored and are eliminated in urine, making them less likely to reach toxic levels.

5. Sugar alcohols have anticariogenic properties and can protect the teeth by decreasing demineralization, enhancing remineralization, or increasing salivary flow, even in the presence of a fermentable carbohydrate. Name 3 sugar alcohols.

• A. Sorbitol
• B. Mannitol
• C. Xylitol
• D. Erythritol

Correct answer: D

Rationale: Sugar alcohols such as sorbitol, mannitol, and xylitol are commonly used in sugar-free products and have properties that help protect teeth from caries by promoting remineralization and increasing salivary flow. Erythritol is another common sugar alcohol used as a sweetener in various products, but it was not listed in the question.
