The nurse is caring for a child in traction with a fractured femur. Which action will the nurse complete while caring for this client?

A. Video games and other stimulating electronic media before bedtime can interfere with sleep onset and quality by increasing arousal and exposure to blue light, which suppresses melatonin production. Encouraging gaming before bed is contrary to sleep hygiene recommendations for school-aged children.

B. Limiting access to electronic devices during bedtime supports healthy sleep patterns, reduces exposure to inappropriate content, and encourages family interaction or reading. Current pediatric guidelines recommend removing TVs, computers, and mobile devices from the bedroom to prevent sleep disturbances and excessive media use.

C. Having electronic devices in the child’s bedroom increases the risk of excessive screen time, sleep disruption, and reduced physical activity. Devices should instead be located in shared family spaces to allow for monitoring and balanced use.

D. The American Academy of Pediatrics recommends no more than 1–2 hours of recreational screen time per day for school-aged children. Three hours exceeds this limit and does not align with evidence-based guidance on healthy media use.

A. Deficiency of Factor IX is responsible for hemophilia B, also called Christmas disease. Like hemophilia A, it is X-linked recessive and primarily affects males, but treatment and factor replacement differ because Factor IX is administered instead of Factor VIII. Misidentifying the factor could lead to inappropriate treatment.

B. Hemophilia A results from a deficiency of Factor VIII, a key protein in the intrinsic pathway of the coagulation cascade. Factor VIII works with Factor IX to activate Factor X, ultimately converting prothrombin to thrombin and fibrinogen to fibrin, forming a stable clot. Without sufficient Factor VIII, the child experiences: Prolonged bleeding after minor cuts or injuries, Spontaneous bleeding episodes, often into joints (hemarthroses) or muscles, Easy bruising, Nosebleeds and prolonged bleeding after dental procedures, Potential life-threatening bleeding if untreated. Factor VIII replacement therapy is the cornerstone of treatment, either prophylactically or during acute bleeding episodes. Education includes proper administration, activity precautions, and early recognition of bleeding.

C. Factor X deficiency is a rare coagulation disorder unrelated to hemophilia A. Deficiency causes bleeding tendencies but involves a different pathway and treatment approach.

D. Stuart-Prower factor refers to Factor X, also not involved in hemophilia A. Confusing this could delay correct treatment and risk severe bleeding.
