Nursing Elites

1. Which of the following is NOT a physiological role of proteins?

• A. Providing resistance to disease
• B. Regulating fluid balance
• C. Repairing tissue
• D. Serving as the primary source of energy

Correct answer: D

Rationale: Proteins play a diverse range of physiological roles in the body, such as providing resistance to disease, regulating fluid balance, and repairing tissues. However, they are not the primary source of energy for the body. Carbohydrates and fats typically fulfill this role. Therefore, choice D is the correct answer, as it is not a function that proteins perform. Conversely, choices A, B, and C are all physiological functions of proteins, making them incorrect responses to this particular question.

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. What dietary strategy would most likely be used as part of lifestyle management to reduce the risk of coronary heart disease?

• A. Avoid foods that contain polyunsaturated fat
• B. Limit saturated fat to less than 10 percent of total calories
• C. Limit alcohol intake to one drink daily for women and two drinks daily for men
• D. Avoid consumption of fish and shellfish

Correct answer: C

Rationale: Limiting alcohol intake is part of a strategy to reduce the risk of coronary heart disease by avoiding the negative cardiovascular effects associated with excessive alcohol consumption.

4. Which of the following interventions should be considered the highest priority when caring for June, who has hemiparesis secondary to a stroke?

• A. Position June in an upright lateral position
• B. Perform range of motion exercises
• C. Apply antiembolic stockings
• D. Use hand rolls or pillows for support

Correct answer: C

Rationale: The correct answer is C, 'Apply antiembolic stockings'. In the case of a patient who has experienced a stroke and is suffering from hemiparesis, the highest priority intervention is to prevent further complications such as deep vein thrombosis (DVT), which can be life-threatening. Antiembolic stockings are used to increase venous blood flow velocity and reduce the risk of DVT. Choice 'A', positioning June in an upright lateral position, while important for overall care, is not the highest priority. Choice 'B', performing range of motion exercises, is an important part of recovery but not the immediate priority. Choice 'D', using hand rolls or pillows for support, is also a valuable intervention but does not address the most pressing risk of further complications.

5. Why is there an ethical dilemma?

• A. Because the law does not clearly state what is right from what is wrong
• B. Because morality is subjective and it differs from each individual
• C. Because the patient's right coincide with the nurse's responsibility
• D. Because the nurse lacks ethical knowledge to determine what action is correct and what action is unethical

Correct answer: C

Rationale: The correct answer is C because an ethical dilemma arises when the patient's rights conflict with the nurse's responsibilities, requiring a careful balance to ensure ethical care delivery. Choices A and B are incorrect because ethical dilemmas are not solely about legal or subjective moral issues. Choice D is incorrect as nurses are generally equipped with ethical knowledge through education and training, and ethical dilemmas are more about conflicting values and responsibilities rather than a lack of knowledge.
