A nurse is reinforcing client teaching about preventing stress injuries. Which of the following statements by the client indicates an understanding of teaching?

Rationale:

A. Home telephone number: A home telephone number is an acceptable second client identifier under The Joint Commission's guidelines, as it is specific to the individual and can help prevent medication errors when used alongside another unique identifier.

B. Medical diagnosis: A medical diagnosis is not a unique identifier and may be shared by multiple clients in the same facility. It does not provide adequate confirmation of a client's individual identity.

C. Date of admission: Admission dates are not unique and may be the same for several clients. This information is insufficient as a reliable identifier for ensuring safe medication administration.

D. Facility room number: Room numbers can change during hospitalization and are not considered safe identifiers. Clients may be transferred, making room number an unreliable and non-permanent method of identification.

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.
