The nurse is caring for a 15-year-old adolescent who is admitted with a diagnosis of bulimia nervosa. The adolescent's vital signs are stable, but the nurse notes that the client has dry skin and appears thin. What is the nurse's priority action?

Correct Answer: C

Rationale: In clients with bulimia nervosa, electrolyte imbalances are common due to purging behaviors and can lead to severe complications. Monitoring electrolyte levels is essential to detect and manage any imbalances promptly, as they can be life-threatening.

Correct Answer: C

Rationale: Placing infants on their stomach after feeding increases the risk of sudden infant death syndrome (SIDS). It is important to educate parents to always place infants on their back to sleep to reduce this risk.

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: B

Rationale: When administering ear drops to a child under three years old, it is essential to pull the earlobe down and back. This positioning helps straighten the external auditory canal, facilitating the proper administration of the ear drops. Pulling the earlobe down and back in young children aims to ensure that the medication reaches the intended area for optimal effectiveness.

Correct Answer: A

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: A

Rationale: The practical nurse should suggest playing peek-a-boo to the parents of a 7-month-old infant to encourage visual stimulation. Peek-a-boo is a suitable game for this age group as it helps develop visual tracking skills and the concept of object permanence. By covering and uncovering their face or a toy, the infant learns that things still exist even when they cannot be seen, promoting cognitive development and visual engagement.

Correct Answer: D

Rationale: The presence of swollen red spots and fluid-filled blisters may indicate a contagious condition. Implementing transmission precautions is crucial to prevent the spread of the infection to others in the clinic setting.

Correct Answer: B

Rationale: After an appendectomy, it is important for the child to avoid strenuous activities for at least 2 weeks to allow for proper healing. Resuming normal activities too soon can put unnecessary strain on the healing process and increase the risk of complications.

Correct Answer: A

Rationale: Administering a bronchodilator will help open the airways and improve breathing.
