Nursing Elites

1. A healthcare provider is teaching a client about nutritional requirements necessary to promote wound healing. Which of the following nutrients should the provider include in the teaching?

• A. Protein
• B. Calcium
• C. Vitamin B1
• D. Vitamin D

Correct answer: Protein

Rationale: Protein is crucial for wound healing as it plays a vital role in tissue repair and synthesis. Calcium is important for bone health but not directly related to wound healing. Vitamin B1 is essential for energy production but not specifically significant for wound healing. Vitamin D is essential for bone health and immune function but is not a primary nutrient emphasized for wound healing.

2. Inadequate intake of vitamin A occurs in lower socioeconomic groups due to a lack of resources to purchase and consume vegetables and fruits.

• A. Both the statement and the reason are correct and related.
• B. Both the statement and the reason are correct but are not related.
• C. The statement is correct, but the reason is not correct.
• D. The statement is not correct, but the reason is correct.

Correct answer: A

Rationale: Both the statement and the reason are correct and related. Inadequate intake of vitamin A in lower socioeconomic groups is due to a lack of resources to purchase and consume vegetables and fruits. This is supported by the fact that the average intake in the United States meets the Recommended Dietary Allowance (RDA) for vitamin A intake, except in lower socioeconomic groups. These individuals often lack the financial means to buy, prepare, and eat a variety of fruits and vegetables, leading to deficiencies. It's important to note that because vitamin A can be stored in the liver, most adults have sufficient quantities to maintain health. Choices B, C, and D are incorrect because the statement and reason are both accurate and logically connected, as the lack of resources directly impacts the ability to obtain necessary sources of vitamin A.

3. 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: 166

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.

4. Each statement accurately describes the physical effects of food on periodontal health, except one. Which is the exception?

• A. Supragingival plaque biofilm adhesion is influenced by frequent consumption of monosaccharides
• B. Supragingival plaque biofilm adhesion is influenced by frequent consumption of disaccharides
• C. Poor nutrition has an adverse effect on the periodontium
• D. Chewing soft, spongy foods stimulates salivary flow

Correct answer: D

Rationale: The correct answer is D. Chewing soft, spongy foods does not stimulate salivary flow; rather, firm, fibrous foods like fruits and vegetables do. Soft foods can stick to teeth, promoting plaque buildup. Choices A, B, and C are accurate: Supragingival plaque biofilm adhesion is influenced by both monosaccharides and disaccharides, while poor nutrition can indeed have adverse effects on the periodontium.

5. Where should a nurse auscultate the apex beat?

• A. At the fifth intercostal space, along the midclavicular line
• B. At the mid-sternum
• C. 2 inches to the left of the lower end of the sternum
• D. 1 inch to the left of the xiphoid process

Correct answer: A

Rationale: The correct location to auscultate the apex beat is at the fifth intercostal space, along the midclavicular line. This is where the apical impulse, also known as the point of maximal impulse (PMI), can be best heard. Choices B, C, and D are incorrect anatomical locations for auscultating the apex beat, which makes them incorrect choices. Auscultating at the correct location allows healthcare providers to assess the heart's function and detect any abnormalities in heart sounds, which is crucial for comprehensive patient care.
