Nursing Elites

1. Macronutrients include each of the following except one. Which one is the exception?

• A. Fat
• B. Polyunsaturated fatty acids
• C. Carbohydrate
• D. Protein

Correct answer: D

Rationale: Macronutrients are nutrients required by the body in large amounts to provide energy and include carbohydrates, fats, and proteins. While protein is essential for the body, it is not classified as a macronutrient. Proteins are made up of amino acids and serve various functions in the body, such as building and repairing tissues, but they are not a direct energy source like carbohydrates and fats. Therefore, protein is the exception among the listed options, making it the correct answer. Choice A, Fat, Choice B, Polyunsaturated fatty acids, and Choice C, Carbohydrate, are all examples of macronutrients that provide energy and support various bodily functions.

2. Through the client’s health history, you gather that Mr. Dizon smokes and drinks coffee. When taking the blood pressure of a client who recently smoked or drank coffee, how long should the nurse wait before taking the client’s blood pressure for accurate reading?

• A. 15 minutes
• B. 30 minutes
• C. 1 hour
• D. 5 minutes

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

3. What does oliguria lead to in patients with acute kidney injury?

• A. Hypophosphatemia and overgrowth of bone tissue
• B. An increase in blood potassium levels due to excessive excretion of parathyroid hormone
• C. Sodium retention and elevated levels of potassium
• D. Edema due to increased urine production

Correct answer: C

Rationale: In patients with acute kidney injury, oliguria (reduced urine output) often results in sodium retention and hyperkalemia (elevated levels of potassium). This is due to the kidneys' decreased capacity to excrete these substances. Choice A is incorrect because hypophosphatemia and overgrowth of bone tissue are not direct consequences of oliguria in acute kidney injury. Choice B is incorrect because an increase in blood potassium levels is not caused by excessive excretion of parathyroid hormone but rather by decreased excretion of potassium. Choice D is incorrect because edema is not caused by increased urine production but rather by fluid overload due to decreased urine output.

4. What kinds of foods do people who live in food deserts typically lack?

• A. fresh fruits and vegetables
• B. energy-dense foods
• C. beef or pork products
• D. grains and cereals

Correct answer: A

Rationale: Correct Answer: Fresh fruits and vegetables are often unavailable in food deserts, where access to nutritious, perishable foods is limited. Choice B, energy-dense foods, is incorrect because these are more likely to be available in food deserts, contributing to health issues. Choice C, beef or pork products, is incorrect as the focus is on the lack of fresh produce. Choice D, grains and cereals, is incorrect as these are staple foods that are more commonly found even in areas classified as food deserts.

5. 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.
