Rationale: The correct answer is A. Duchenne muscular dystrophy is an inherited X-linked recessive disorder that primarily affects male children in the family. Since it is X-linked, sons inherit the mutation from their mothers who are carriers of the abnormal gene. Therefore, the nurse should explain to the parents that any future sons they have would have a 50% chance of inheriting the mutation and having DMD, while daughters would have a 50% chance of being carriers like the mother.

Correct Answer: D

Rationale: Providing positive feedback is essential in reinforcing correct behaviors. By praising the mother for properly administering the ferrous sulfate to her 11-month-old, the nurse can encourage her to continue following the correct procedure. This positive reinforcement can boost the mother's confidence and adherence to the recommended administration method, ultimately benefiting the infant's health.

Correct Answer: B

Rationale: The correct intervention to help prevent injury during a seizure is to keep the side rails padded and in an upright position. This measure helps to ensure the child's safety by preventing falls or accidental injuries. Using a padded tongue depressor or restraining the child can potentially cause harm and are not recommended. Placing a padded helmet is not a standard intervention for seizure safety in this scenario.

Correct Answer: B

Rationale: Recording the height and weight of children is crucial in detecting growth abnormalities like hypopituitarism and hyperpituitarism. Inappropriate growth patterns, such as disproportionate weight gain or stunted height, can be indicative of these conditions. Regular monitoring of height and weight is a fundamental nursing intervention that can aid in the early identification and management of pituitary-related disorders in children.
