1. Churns chyme and has an environment of pH2; holds 4-6 cups of food:

Correct answer: A

Rationale: The stomach churns food into chyme and has a highly acidic environment (pH 2) to aid in the digestion of proteins and other nutrients.

2. Which foods are the biggest contributors of saturated fats consumed by Americans?

Correct answer: D

Rationale: The correct answer is D: Cheese, pizza, desserts, and chicken. These foods are significant contributors to the intake of saturated fats in the American diet, often found in processed and fast foods. Choices A, B, and C are incorrect because while butter, coconut, and palm oils (A) are sources of saturated fats, they are not the biggest contributors in the American diet. Corn oil (B) is a source of unsaturated fats, and meat and milk (C) contain saturated fats but are not the primary contributors compared to cheese, pizza, desserts, and chicken.

3. In a patient with liver cirrhosis, weight gain due to fluid retention can mask the symptoms of what condition?

Correct answer: D

Rationale: In a patient with liver cirrhosis, weight gain due to fluid retention can mask Protein-Energy Malnutrition (PEM) symptoms. This can lead to an increase in weight, making it challenging to identify weight loss or muscle wasting associated with PEM. Therefore, option D is correct. Options A, B, and C are incorrect because fluid retention and weight gain related to liver cirrhosis do not necessarily hide the symptoms of liver failure, gallbladder disease, or heart failure.

4. To successfully complete the tasks of older adulthood, an 85 year old who has been a widow for 25 years should be encouraged to:

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. What is the primary purpose of dietary fiber in the diet?

Correct answer: D

Rationale: The primary purpose of dietary fiber in the diet is to reduce cholesterol levels. While it does aid in digestion by promoting regular bowel movements, its main role is in lowering cholesterol. Choice A is partially correct but not the primary purpose. Choice B is incorrect as fiber is not a direct source of energy. Choice C is also incorrect as the primary role of fiber is not in the absorption of vitamins.
