The nurse is providing discharge instructions to the parents of a 2-year-old child who had an orchiopexy to correct cryptorchidism. Which statement by the parents indicate that further teaching is necessary?

A. Shingles: This is a viral infection caused by the varicella-zoster virus, which also causes chickenpox. It typically manifests as a painful rash that develops into fluid-filled blisters.

B. Athlete's foot: This is a fungal infection of the skin on the feet, particularly between the toes. It causes itching, burning, and cracked, flaking skin.

C. Fever blister: Also known as a cold sore, this is a viral infection caused by the herpes simplex virus. It typically appears as a cluster of small, fluid-filled blisters on or around the lips.

D. Pinworms: This is a parasitic infection caused by tiny, white worms that infect the intestines. It commonly causes anal itching, particularly at night, due to the female worms laying eggs around the anal area.

A. "There are a few causes of this condition and they tell me my child has crossed eyes because of a muscle imbalance.": This statement demonstrates the mother's comprehension of the cause of strabismus, which can indeed result from a muscle imbalance affecting the alignment of the eyes. Understanding the cause is essential for the mother to grasp the rationale behind treatment interventions.

B. "I will have my child wear an eye patch over the good eye to help strengthen the weak eye.": Patching the stronger eye is a common treatment approach for strabismus to encourage the weaker eye to become stronger and improve alignment. The mother's statement indicates her awareness of this treatment modality.

C. "My child will outgrow this by the time he is 2 years old and be able to see just fine.": While some cases of strabismus may improve as a child grows, not all cases resolve spontaneously. This statement suggests the mother's belief in the possibility of spontaneous resolution, which may be accurate in some instances but not guaranteed for all cases of strabismus.

D. "If this eye patch does not work I know we will have to do surgery to correct my child's crossed eyes.": Surgery is indeed an option for correcting strabismus, especially if conservative measures like patching do not yield satisfactory results. The mother's understanding of this potential treatment escalation reflects her grasp of the condition's management plan.
