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 C
Explanation
Rationale:
A. Institutional policies and procedures: While helpful in guiding facility-specific protocols, policies do not override state regulations. An institution may allow tasks that exceed or fall short of legal scope, so this should not be the primary reference.
B. Written prescription from the provider: A provider’s order does not define or expand a nurse’s legal scope of practice. Even with a valid order, the nurse must independently verify whether they are legally permitted to carry out the task.
C. State Nurse Practice Act: The Nurse Practice Act (NPA) is the legal authority that defines what licensed nurses are permitted to do in their state. It is the most authoritative resource to determine whether a task is within the nurse’s legal scope of practice.
D. Verbal direction from the nurse manager: Even when given by a superior, verbal instructions must still comply with state law. A nurse manager’s guidance cannot authorize a task that lies outside the nurse’s legal scope.
Correct Answer is B
Explanation
Rationale:
A. Monitor the client's vital signs every hour following the procedure: Vital signs, especially blood pressure, should be monitored more frequently—usually every 5 to 15 minutes immediately after epidural initiation—to assess for hypotension, a common complication.
B. Review the client's platelet count level prior to the procedure: A low platelet count increases the risk of epidural hematoma during needle insertion. Reviewing coagulation status is essential to ensure it's safe to proceed with epidural placement.
C. Inform the client that their bladder should be full before the procedure: The bladder should be emptied, not full, prior to the procedure. A full bladder increases discomfort, impairs fetal descent, and may lead to urinary retention after the epidural is placed.
D. Obtain the client's consent following the procedure: Informed consent must be obtained before any invasive procedure, including epidural anesthesia. Performing the procedure without prior consent violates patient autonomy and legal standards.
