1. How do foods or supplements containing significant amounts of plant sterols help lower LDL cholesterol levels?

A. reducing cholesterol synthesis
B. suppressing inflammation
C. reducing blood clotting
D. interfering with cholesterol and bile absorption

Correct answer: D

Rationale: Plant sterols interfere with cholesterol and bile absorption in the intestines. This interference helps lower LDL cholesterol levels by reducing the amount of cholesterol that enters the bloodstream. Choices A, B, and C are incorrect because plant sterols primarily work by interfering with cholesterol and bile absorption, not by reducing cholesterol synthesis, suppressing inflammation, or reducing blood clotting.

2. In approximately what percentage of cases is the prevalence seen?

A. Type 1 Diabetes
B. Type 2 Diabetes
C. N/A
D. N/A

Correct answer: A

Rationale: The correct answer is A, Type 1 Diabetes. The prevalence of Type 1 Diabetes is seen in approximately 5% to 10% of cases. This statement highlights a key epidemiological characteristic of Type 1 Diabetes. Choice B, Type 2 Diabetes, is incorrect because the prevalence mentioned does not align with Type 2 Diabetes, which has a much higher prevalence in the general population. Choices C and D are not relevant to the question and can be disregarded.

A. Hemoglobin
B. Collagen

4. While evaluating the meal choices of a client with major depressive disorder and a prescription of Phenelzine, which of the following selections should the nurse identify as appropriate?

A. Cheddar cheese
B. Smoked salmon
C. Strawberry yogurt
D. Pepperoni pizza

Correct answer: C

Rationale: The correct answer is C, 'Strawberry yogurt.' This choice is appropriate because it does not contain high levels of tyramine, which can lead to a dangerous interaction with Phenelzine, a monoamine oxidase inhibitor. Tyramine-rich foods, like aged cheeses (such as cheddar cheese) and cured meats (like smoked salmon and pepperoni), should be avoided by individuals taking Phenelzine to prevent hypertensive crisis. Strawberry yogurt is a safer option for the client in this scenario.
