Nursing Elites

1. Which type of lipid is solid at room temperature?

• A. Cholesterol
• B. Phospholipid
• C. Saturated fat
• D. Trans fat

Correct answer: C

Rationale: Saturated fats, such as those found in butter and lard, are typically solid at room temperature due to the lack of double bonds, which allows the fat molecules to pack closely together. Cholesterol (Choice A) is a steroid, not a fat, and while it's solid at room temperature, it doesn't fit the general category of 'lipid' in the context of this question. Phospholipids (Choice B) are a major component of all cell membranes and can be both solid and liquid at room temperature depending on their composition. Trans fats (Choice D) can also be solid or liquid at room temperature, but they are not typically referred to as 'lipids' in a general sense.

2. Which enzyme is most essential for hydrolyzing large protein molecules?

• A. Gastric lipase
• B. Pepsin
• C. Mucus
• D. Intrinsic factor

Correct answer: B

Rationale: Pepsin, choice B, is the correct answer as it is a proteolytic enzyme that is essential for the breakdown of large protein molecules in the stomach. Gastric lipase, choice A, is incorrect because it primarily targets fats, not proteins, hence it is not involved in protein hydrolysis. Mucus, choice C, is incorrect as it serves to protect the stomach lining from acidic gastric juices and does not play a direct role in protein digestion. Intrinsic factor, choice D, is incorrect as it is vital for the absorption of Vitamin B12 in the small intestine and doesn't participate in the process of hydrolyzing proteins.

3. 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.

4. Which types of diabetes are characterized by the body's cells becoming resistant to insulin? (Select all that apply)

• A. Gestational diabetes
• B. Type II diabetes
• C. Type I diabetes
• D. Both A and B

Correct answer: D

Rationale: In both gestational diabetes and Type II diabetes, the body's cells become resistant to insulin, leading to elevated blood glucose levels. Insulin resistance in these types of diabetes prevents glucose from entering the cells, causing it to accumulate in the bloodstream. On the other hand, Type I diabetes is characterized by the body's inability to produce insulin because the immune system mistakenly attacks and destroys the insulin-producing cells in the pancreas. Therefore, the correct answer is both A and B. Choice C, Type I diabetes, is not characterized by insulin resistance but rather by the body's inability to produce insulin. Therefore, it is incorrect. Choice D, Both A and B, includes the correct options of gestational diabetes and Type II diabetes, making it the correct answer.

5. Which of the following questions illustrates the group role of encourager?

• A. What were you saying?
• B. Who wants to respond next?
• C. Where do you go from here?
• D. Why haven’t we heard from you?

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.
