A nurse is collecting data from a client who is in Buck's traction. Which of the following findings indicates the traction is functioning correctly?

Rationale:

A. The restraint tie strap is tied into a knot: Restraint straps should be secured using a quick-release or slipknot, not a firm knot. A tight knot can delay removal in an emergency and increases the risk of injury to the client.

B. The restraint is attached to the side rails of the bed: Attaching restraints to side rails is unsafe, as moving the rails can apply excess force or cause injury. Restraints should be secured to a stable part of the bed frame to prevent unintentional tightening or injury.

C. The skin under the restraint is cool and has changed color: Changes in skin temperature or color can indicate impaired circulation, a serious complication of improper restraint use. These findings require immediate attention and potential removal of the restraint.

D. The nurse can insert two fingers under the restraint: Being able to insert two fingers ensures the restraint is snug but not too tight, allowing adequate circulation and reducing the risk of skin breakdown. This is a standard guideline for safe restraint application.

Rationale:
• Compartment syndrome: Casts can restrict swelling, increasing pressure within the compartment. Moderate toe edema and capillary refill slowing from brisk to 3 seconds are warning signs. Without prompt intervention, tissue perfusion may decline, leading to ischemia.

• Edema of toes: Progressive edema signals impaired venous return or rising intracompartmental pressure. It reflects worsening limb status under the cast. This change, with slowed refill, supports risk for compartment syndrome.

• Malunion: Malunion develops over weeks due to misalignment during healing. No imaging or prolonged healing time is reported. Acute symptoms like swelling and pain don’t indicate this long-term issue.

• Physeal damage: Growth plate injury would affect long-term limb development. The adolescent shows intact toe movement and normal limb function otherwise. No evidence of joint or bone disruption is presented.

• Inability to ambulate: The femur fracture and cast already restrict ambulation. Lack of walking is expected at this stage. It doesn't suggest any specific complication like infection or compartment syndrome.

• Infection: Fever is low-grade and expected post-injury or from opioids. No redness, drainage, or systemic illness is present. Pain is stable and localized, not escalating or spreading.

• Decreased dorsalis pedis pulse: Pulses are 2+, meaning circulation is present and adequate. Decreased or absent pulse would indicate severe compromise, but that is not seen here. It does not reflect early compartment syndrome.
