1. Intrinsic factor from the stomach is needed for the absorption of which vitamin?

Correct answer: A

Rationale: The correct answer is A: vitamin B12. Intrinsic factor is a glycoprotein produced by the stomach that is necessary for the absorption of vitamin B12 in the small intestine. Vitamin B12 binds to intrinsic factor in the stomach, forming a complex that is then absorbed in the ileum. This absorption process is crucial for preventing vitamin B12 deficiency. Choices B, C, and D are incorrect because they do not require intrinsic factor for absorption. Folate is absorbed in the small intestine through a different mechanism, niacin can be absorbed in the small intestine without the need for intrinsic factor, and vitamin B6 does not rely on intrinsic factor for absorption.

2. Which of the following is not correct?

Correct answer: B

Rationale: A product with 15% Daily Value (DV) of calcium is considered a good source, not a low source. Typically, anything 10-19% DV is considered a good source.

3. Nutritional goals for a patient wishing to modify eating patterns should adhere to each, except one. Which is the exception?

Correct answer: B

Rationale: Nutritional goals should be measurable, realistic, and achievable. They should not be immediate, as sustainable changes take time.

4. A nurse is teaching a group of clients who are at risk for heart disease about decreasing saturated fats in their diet. Which of the following fats should the nurse recommend the clients use when cooking?

Correct answer: C

Rationale: Canola oil is lower in saturated fats compared to palm oil, peanut oil, and stick margarine, making it a healthier option for clients at risk for heart disease. Palm oil is high in saturated fats, peanut oil has a moderate amount of saturated fats, and stick margarine is also high in saturated fats and trans fats, which are not heart-healthy choices.

5. A client says to the nurse “I am worthless person, I should be dead” The nurse best replies:

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.
