A sexually active 16-year-old male is allergic to latex. He should be taught that:

Rationale:
A. Avoiding contact sports is important long-term, but it is not the immediate priority for an unstable slipped capital femoral epiphysis (SCFE).
B. While limited weight-bearing is essential, prolonged wheelchair use is typically only required until surgical stabilization, not as a permanent measure.
C. Ice or heat applications provide minimal benefit for SCFE; they do not address the mechanical instability of the hip.
D. Surgical repair is the definitive treatment for an unstable SCFE. Prompt surgical intervention, usually in situ pinning, is necessary to prevent further slippage, reduce the risk of avascular necrosis, and restore hip stability. Early recognition and timely surgery are critical components of anticipatory guidance for the patient and family

Rationale:
A. Hypoxia may cause some stress responses but is not the most common cause of temperature instability in a newborn.
B. Congenital heart disease can affect perfusion but typically does not directly cause temperature instability.
C. Polycythemia may affect circulation but is not a primary cause of abnormal temperature regulation.
D. Sepsis is a common cause of temperature instability in newborns, manifesting as hypothermia or hyperthermia. Newborns have immature thermoregulatory systems, and infections can easily disrupt temperature homeostasis, making temperature instability an important early sign of neonatal sepsis.
