1. Which enzyme initiates protein digestion in the stomach?

• A. Pepsin
• B. Salivary Amylase
• C. CCK
• D. Secretin

Correct answer: A

Rationale: Pepsin is the enzyme that initiates protein digestion in the stomach. It breaks down proteins into smaller peptides, aiding in their further digestion and absorption in the intestines. Salivary Amylase (Choice B) functions in breaking down dietary carbohydrates in the mouth, not proteins. CCK (Choice C) and Secretin (Choice D) are hormones involved in the digestion of fats and carbohydrates, not proteins. Therefore, Choices B, C, and D are incorrect in the context of protein digestion in the stomach.

2. The dietary guidelines for Americans recommend consuming:

• A. nutrient dense foods
• B. non-essential amino acids
• C. energy dense foods
• D. organically grown foods

Correct answer: A

Rationale: The guidelines emphasize nutrient-dense foods that provide essential vitamins, minerals, and other nutrients without excessive calories, sugars, or unhealthy fats.

3. The major determinant of a person's total cholesterol levels is the amount of cholesterol in their diet.

• A. True
• B. False
• C.
• D.

Correct answer: B

Rationale: It is false that the major determinant of a person's total cholesterol levels is the amount of cholesterol in their diet. While dietary cholesterol can have some impact on total cholesterol levels, it is not the major determinant. The amount and types of fats consumed, particularly saturated and trans fats, have a more significant impact on blood cholesterol levels. Therefore, a diet high in these types of fats can lead to high cholesterol, irrespective of the amount of dietary cholesterol consumed. This is why it is essential to maintain a balanced diet with a limited intake of saturated and trans fats.

• C. Disconnect the drainage bag, obtain a sterile syringe and draw the specimen from the drainage bag
• D. Disconnect the tube, obtain a sterile syringe and draw the specimen from the tube

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

5. Which of the following best describes Primary Nursing?

• A. Assigning a nurse to lead a team of registered nurses in the care of a patient from admission to discharge
• B. Assigning a nurse to perform administrative tasks in a healthcare setting

• D. Assigning a nurse to be the main caregiver responsible for coordinating all aspects of care for a group of patients

Correct answer: A

Rationale: Primary Nursing involves assigning a dedicated nurse to lead a team of registered nurses in the care of a patient from admission to discharge. This approach ensures continuity and personalized care. Choices B and C are incorrect as they do not accurately describe Primary Nursing. Choice D is incorrect as it refers to a different care delivery model.
