Nursing Elites

1. 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.

2. A nurse is teaching a client who needs to increase their daily fluid intake. Which of the following foods has the highest percentage of water by weight?

• A. Yogurt
• B. Milk
• C. Lettuce
• D. Honey

Correct answer: C

Rationale: The correct answer is Lettuce. Lettuce has the highest percentage of water by weight among the options provided, making it an excellent choice to increase fluid intake. Yogurt and milk have some water content but are not as high in water percentage as lettuce. Honey, on the other hand, contains very little water and is not a good choice for increasing fluid intake.

3. Where is Vitamin K synthesized?

• A. by bacteria in the GI tract
• B. by the body by sunlight
• C. deficiency is called beriberi
• D. found in vegetable oils

Correct answer: A

Rationale: Vitamin K is synthesized by bacteria in the gastrointestinal tract. Choice B is incorrect as the synthesis of Vitamin D, not K, can be induced by sunlight exposure. Choice C is incorrect as beriberi is a condition caused by thiamine (Vitamin B1) deficiency, not Vitamin K. Choice D is incorrect as Vitamin E is commonly found in vegetable oils, not Vitamin K.

4. What is tocopherol?

• A. Vitamin B1
• B. Vitamin B2
• C. Vitamin B3
• D. Vitamin E

Correct answer: D

Rationale: Tocopherol is another name for Vitamin E, a fat-soluble antioxidant that helps protect cell membranes from oxidative damage. Choices A, B, and C are incorrect as tocopherol is specifically related to Vitamin E and not Vitamin B1, B2, or B3.

5. What laboratory value would be considered a high-risk measure for coronary heart disease assessment?

• A. triglycerides > 150 mg/dL
• B. BMI > 31
• C. LDL cholesterol < 128 mg/dL
• D. blood pressure of 128/82 mmHg

Correct answer: B

Rationale: The correct answer is B: BMI > 31. A BMI over 31 is considered a high-risk factor for coronary heart disease as it indicates obesity, which is strongly linked to cardiovascular issues. Triglycerides > 150 mg/dL (choice A) can contribute to heart disease risk but are not as specific as BMI in assessing overall risk. LDL cholesterol < 128 mg/dL (choice C) is actually a desirable level, indicating lower risk. A blood pressure of 128/82 mmHg (choice D) is within normal range and not a high-risk measure specifically for coronary heart disease.
