Correct Answer: A

Rationale: The correct answer is A because an undescended testicle can reduce fertility. Even after surgical correction (orchiopexy), fertility rates may be reduced, especially when one testis remains undescended. The statement in choice B is incorrect as the testicle should have descended into the scrotum by the time the infant is 4-6 months old. While choice C is true that surgical correction can reduce the risk of testicular tumors, the question focuses on the father's understanding of the information presented, which is better reflected in choice A. Choice D is incorrect because the optimal time for surgical correction of an undescended testicle is typically around 6-18 months of age, not necessarily at the time of diagnosis.

Correct Answer: B

Rationale: The Model of Human Occupation (MOHO) emphasizes the child's subjective experience of their abilities, focusing on their motivation, roles, habits, and routines. It considers how these factors influence their occupational performance. MOHO helps occupational therapists understand how a child's perceptions of their abilities impact their engagement in meaningful activities and occupations.

Correct Answer: A

Rationale: Minimal change nephrotic syndrome (MCNS) is characterized by massive proteinuria, hypoalbuminemia, and edema. Proteinuria results from the loss of proteins, particularly albumin, in the urine, leading to hypoalbuminemia. The low oncotic pressure due to hypoalbuminemia causes fluid to shift into the interstitial spaces, resulting in edema. These clinical manifestations are classic signs of MCNS and help differentiate it from other renal conditions.

Correct Answer: D

Rationale: The nurse should keep the infant’s elbow restrained to prevent injury to the surgical site.

Correct Answer: B

Rationale: Hypospadias is a congenital condition where the opening of the urethra is on the underside of the penis. Surgical repair is the primary treatment for hypospadias and is usually recommended to be done before 18 months of age. This timing is preferred for optimal cosmetic and functional outcomes. Waiting until preschool age for corrective surgery may increase the complexity of the procedure and potential complications. Correcting hypospadias does not impact the risk of testicular cancer.
