Correct Answer: D

Rationale: A hemoglobin A1c of 10% indicates poor blood glucose control, reflecting an average blood sugar level over the past 2-3 months. To improve control, the plan of care should be comprehensive. Increasing the frequency of self-monitoring blood glucose helps track changes in blood sugar levels. Discussing dietary changes to reduce carbohydrate intake can aid in better blood sugar management. Reviewing the client's insulin administration technique ensures proper medication dosing. Therefore, all the options (increasing monitoring, discussing dietary changes, and reviewing insulin administration) are essential components of the plan of care to address the client's poor blood glucose control.

Correct Answer: C

Rationale: When a client expresses concerns about family dynamics, it is important to explore their feelings and reactions to the situation. By asking about the client's response to his mother's anger, the nurse can gain insight into the client's emotions, thoughts, and coping mechanisms. Understanding these aspects is crucial in providing appropriate support and guidance.

Correct Answer: A

Rationale: Duchenne muscular dystrophy is an X-linked recessive disorder caused by mutations in the DMD gene on the X chromosome. This disorder primarily affects males because they have one X chromosome, inherited from their mothers, who may be carriers of the mutated gene. Females have two X chromosomes, providing a protective effect as the normal gene on one X chromosome can compensate for the mutated gene on the other. Therefore, the nurse should explain to the parents that Duchenne muscular dystrophy is an inherited X-linked recessive disorder, which is why their son has the disease and why there is a risk of passing it on to future sons.

Correct Answer: D

Rationale: When a baby looks for a hidden object, it demonstrates the development of object permanence. This milestone is significant as it signifies the baby's understanding that objects continue to exist even when they are not visible. It is a crucial aspect of cognitive development in infancy.

Correct Answer: C

Rationale: The correct action for the nurse to implement when the chemotherapy infusion is complete is to flush the mediport with saline and heparin solution. This process helps prevent clotting and ensures the patency of the port, which is essential for future medication administrations and blood draws.
