A 2-year-old child with heart failure (HF) is admitted for replacement of a graft for coarctation of the aorta. Prior to administering the next dose of digoxin (Lanoxin), the nurse obtains an apical heart rate of 128 bpm. What action should the nurse take?

Correct Answer: B

Rationale: Administering the scheduled dose is appropriate in this scenario since the heart rate of 128 bpm is within an acceptable range for a 2-year-old child with heart failure. Monitoring for signs of digoxin toxicity is important; however, the immediate action required is to administer the scheduled dose as prescribed based on the heart rate assessment.

Correct Answer: A

Rationale: The nurse should inform the parents that Duchenne muscular dystrophy is an X-linked recessive disorder, which primarily affects male children in the family. This genetic condition is caused by a mutation in the dystrophin gene located on the X chromosome. Females are usually carriers of the gene mutation and may pass it on to their sons. Daughters of carrier mothers have a 50% chance of being carriers themselves. Understanding the genetics of DMD can help the parents make informed decisions about family planning and genetic counseling.

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.
