The client presents to the wound care clinic with a stage two pressure injury to the sacrum. The wound has been treated in the clinic for three months. Which statement by the client indicates to the nurse that teaching has been effective during this clinic visit?

A. A hydrogel: These dressings are designed to donate moisture to dry, necrotic wound beds to facilitate autolytic debridement. Venous ulcers are often highly exudative due to chronic venous insufficiency and high hydrostatic pressure. Adding moisture to a wet wound can cause periwound maceration and delay healing.

B. An alginate: These highly absorbent dressings are derived from seaweed and are excellent for managing heavy exudate. While many venous ulcers require high absorption, not all present with the same level of drainage. Using an alginate on a dry wound could cause unwanted tissue adherence.

C. A transparent film: These semi-permeable dressings provide a moist environment but have minimal to no absorptive capacity. They are generally unsuitable for the high-drainage environment typically found in venous stasis ulcers. Using them could lead to fluid accumulation and subsequent skin breakdown under the film.

D. Unable to determine since venous ulcers have a variety of presentations: Wound dressing selection must be based on a comprehensive assessment of the specific wound bed characteristics. Factors include the amount of exudate, presence of infection, and the healing stage. No single dressing type is universally appropriate for every venous ulcer.

A. Muscle atrophy: Prolonged immobilization leads to disuse atrophy of the skeletal muscles as they are not subjected to normal tension and workload. After 6 weeks in a cast, a noticeable decrease in the circumference of the calf and thigh muscles is a standard clinical finding.

B. Slow capillary refill: Capillary refill is a measure of peripheral perfusion and should return to normal once the restrictive cast is removed. Unless there is underlying vascular disease, the immobilization itself does not permanently impair the microcirculation of the toes or skin.

C. Inversion contracture: While joint stiffness is common after casting, a specific inversion contracture is not a standard expected finding of simple immobilization. Range of motion is typically restricted in all planes initially, but permanent pathological contractures are avoided through proper positioning and subsequent physical therapy.

D. Diminished pedal pulse: The presence of a cast does not typically cause a permanent decrease in arterial pulse strength once removed. Pulses should be palpable and strong unless a vascular complication occurred during the casting period. Immobilization affects muscle mass rather than arterial lumen integrity.
