A nurse is teaching a group of adolescents about healthy sleep habits. Which of the following statements by an adolescent indicates a correct understanding of the teaching?

A. "My child can participate in noncontact sports like swimming and rowing.": After nephrectomy, protecting the remaining kidney from trauma is essential. Noncontact activities such as swimming and rowing are appropriate because they promote physical activity while minimizing the risk of blunt abdominal injury.

B. "I need to ensure my child avoids salty foods but there are no concerns about physical activity.": While moderate sodium intake supports kidney health, physical activity restrictions are necessary to prevent injury to the single remaining kidney. Ignoring activity precautions places the child at unnecessary risk.

C. "Because my child has only one kidney, I will encourage increased physical activity to strengthen it.": Kidneys do not strengthen with increased physical activity. Excessive or unsafe activity can increase the risk of trauma to the remaining kidney rather than provide protection.

D. "My child will be able to play boxing next year.": Boxing is a high-contact sport with significant risk of abdominal trauma. Participation in contact sports is generally discouraged for children with a single functioning kidney to prevent serious injury.

A. Obtain a urology consult for immediate evaluation: Sudden, severe testicular pain in an adolescent is highly concerning for testicular torsion, a surgical emergency. Prompt urologic evaluation is critical to restore blood flow and prevent irreversible testicular ischemia and loss.

B. Apply heat to the affected area for relief: Heat application is inappropriate in acute scrotal pain and may delay diagnosis and treatment of testicular torsion, potentially worsening ischemic injury.

C. Recommend the client take over-the-counter pain relievers and monitor pain over the next few days: Delaying evaluation in the setting of acute testicular pain risks permanent damage or loss of the testicle. Observation and analgesics alone are unsafe without ruling out torsion.

D. Determine if the adolescent has had exposure to the mumps recently: Mumps orchitis typically presents with gradual onset of testicular pain and swelling, often with systemic symptoms. While history is relevant, immediate evaluation for torsion takes priority.
