Nursing Elites

1. Which enzyme digests fiber in the large intestine?

• A. salivary amylase
• B. pancreatic amylase
• C. cellulase
• D. none of the above

Correct answer: D

Rationale: The correct answer is 'none of the above.' Human digestive enzymes like salivary amylase and pancreatic amylase cannot digest fiber. Instead, fiber is fermented by gut bacteria in the large intestine. Cellulase, which is an enzyme produced by some animals and microorganisms, can break down cellulose found in plants, but it is not a human digestive enzyme, making it an incorrect choice in this context.

2. What level of sodium restriction would be included as part of nutrition therapy for heart failure?

• A. Less than 500 mg per day
• B. 1000 mg to 1500 mg per day
• C. 1500 mg to 3000 mg per day
• D. 3000 to 3500 mg per day

Correct answer: C

Rationale: The correct answer is 1500 mg to 3000 mg per day. This is the level of sodium restriction typically recommended for heart failure patients. It helps manage fluid retention and reduce blood pressure, which are both crucial in treating heart failure. A sodium intake of less than 500 mg per day (Choice A) might be too restrictive and is not typically recommended. Similarly, an intake of 1000 mg to 1500 mg per day (Choice B) falls short of the recommended range. Lastly, an intake of 3000 to 3500 mg per day (Choice D) exceeds the recommended upper limit, potentially exacerbating fluid retention and high blood pressure.

3. Which nursing diagnosis has nutritional implications?

• A. impaired dentition
• B. disruption of gas exchange
• C. self-esteem disturbance
• D. sleep pattern disturbance

Correct answer: A

Rationale: Impaired dentition affects a patient's ability to chew and consume a variety of foods, leading to potential nutritional deficiencies and malnutrition.

4. James wants to know the recommended intake for iron for his gender and age. Which of the following would provide the best answer for James?

• A. EAR
• B. UL
• C. RDA
• D. DV

Correct answer: C

Rationale: The Recommended Dietary Allowance (RDA) is the correct answer for James because it provides the daily intake level that meets the nutrient needs of most healthy individuals in a specific age and gender group. Choice A, EAR (Estimated Average Requirement), represents the average daily nutrient intake level estimated to meet the requirement of half the healthy individuals in a particular life stage and gender group. Choice B, UL (Tolerable Upper Intake Level), is the maximum daily intake unlikely to cause adverse health effects. Choice D, DV (Daily Value), is a general guide used for food labeling that represents how much a nutrient in a serving of food contributes to a daily diet based on a 2000-calorie daily intake.

5. A client is prescribed a 1500-calorie diet. Thirty percent of the calories are to be derived from fat. How many grams of fat should the nurse tell the client to consume per day? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

• A. 21
• B. 49
• C. 60
• D. 50

Correct answer: D

Rationale: To calculate the grams of fat, first, determine the calories from fat by multiplying the total calorie intake (1500 calories) by the percentage of calories from fat (30%), which equals 450 calories from fat. Since 1 gram of fat is equivalent to 9 calories, divide the total calories from fat (450) by the calories in 1 gram of fat (9) to get the answer in grams, which is 50. Therefore, the client should consume 50 grams of fat per day. Choice A (21), Choice B (49), and Choice C (60) are incorrect as they do not reflect the accurate calculation based on the given information.
