A nurse is providing prenatal teaching about iron to a client who follows a vegetarian diet. The nurse should recommend that the client consume which of the following foods to enhance the absorption of nonheme iron?
Boiled eggs
Orange slices
Cheddar cheese
Mixed nuts
The Correct Answer is B
Rationale:
A. Boiled eggs: While eggs contain some iron, they are not known to enhance the absorption of nonheme iron. In fact, certain components in eggs may inhibit iron absorption from plant-based sources.
B. Orange slices: Vitamin C (ascorbic acid) found in citrus fruits like oranges significantly enhances the absorption of nonheme iron by reducing it to a more absorbable form. This makes orange slices an ideal complement to iron-rich plant foods.
C. Cheddar cheese: Dairy products like cheese are low in iron and contain calcium, which can actually compete with iron for absorption in the intestines, reducing its bioavailability rather than enhancing it.
D. Mixed nuts: Although nuts contain some iron, they are also high in phytates, which can inhibit iron absorption. They do not actively enhance nonheme iron uptake and are not the best dietary pairing for this purpose.

Correct Answer is B
Explanation
Rationale:
A. Fidelity: Fidelity involves loyalty, faithfulness, and keeping promises to individuals. While important in one-on-one nursing relationships, it is not the guiding principle when planning for population-wide benefit.
B. Utilitarianism: Utilitarianism is an ethical principle focused on producing the greatest good for the greatest number of people. It is most appropriate when planning community programs that aim to maximize overall health benefits.
C. Autonomy: Autonomy emphasizes respecting individual rights and decision-making. While vital in personal healthcare decisions, it does not directly guide broad community health program planning.
D. Veracity: Veracity refers to truth-telling and honesty in communication. Although essential in client interactions, it does not provide direction in choosing programs that broadly benefit the community.
Correct Answer is C
Explanation
Rationale:
A. Inject into the vastus lateralis: The preferred injection sites for insulin are subcutaneous areas such as the abdomen, upper arms, thighs, or buttocks. The vastus lateralis is used for intramuscular injections, not subcutaneous insulin administration.
B. Roll the syringe gently to ensure mixture of the insulins: Only the NPH (cloudy) insulin should be rolled gently between the hands to mix it evenly before drawing it up. The syringe itself should not be rolled after both insulins are inside, as this may affect accuracy.
C. Draw up regular insulin prior to NPH insulin: When mixing insulins, regular (clear) insulin should be drawn up first to avoid contaminating the vial of regular insulin with the cloudy NPH insulin, which could alter its action and absorption.
D. Use a 15 angle for the injection: Insulin is administered subcutaneously using a 45- to 90-degree angle, depending on the client’s body habitus. A 15-degree angle is too shallow and is used for intradermal injections, not subcutaneous ones.
