Which of these wound dressings can be utilized to treat an infected pressure injury? transparent film hydrocolloids hydrogels calcium alginates

alcium alginates Calcium alginates are typically used on partial or full-thickness draining wounds such as pressure or venous insufficiency ulcers. Alginates are often used on infected wounds due to the likelihood of excessive drainage.

Which type of dressing would be the most appropriate for an infected wound if the goal is to reduce exudate while maintaining a moist wound environment? impermeable film hydrogel foam alginates

alginates Alginates are the optimal choice since they absorb excess exudate while maintaining a moist environment. Since they are permeable and do not provide a barrier against bacteria, they are effective when an open wound cannot be covered with an occlusive dressing.

Moisture retentive dressings such as hydrocolloids, films, and hydrogels can be used for which of the following debridement methods? sharp autolytic enzymatic mechanical

autolytic Autolytic debridement is the removal of nonviable material from a wound through the use of the body's own phagocytic cells. Autolysis is the most selective form of debridement and can be promoted with the addition of moisture-retentive dressings.

Which of the following dressings would be most appropriate for partial or full-thickness wounds exhibiting minimal to moderate drainage? transparent film foams calcium alginates collagen matrix

foams Foams dressings are beneficial for partial-thickness wounds exhibiting minimal to moderate drainage because they are highly absorbent and conform to the patent's skin. They are also permeable to oxygen which reduces the risk of anaerobic infection. Calcium alginates are more appropriate for wounds exhibiting large amounts of drainage.

Which of the following is considered the most occlusive of the moisture-retentive dressings? transparent films foams hydrogels hydrocolloids

hydrocolloids Hydrocolloids are considered the most occlusive of the moisture-retentive dressings. They are also available in less occlusive and semi-permeable forms. Hydrocolloids work best on mild to moderate exudating wounds.

Which of the following wound dressings are most helpful in maintaining a moist wound bed in a superficial wound with minimal drainage? transparent film alginates hydrogels wet-to-dry dressings

hydrogels Hydrogels consist of varying amounts of water and gel-forming materials such as glycerin. Hydrogels are moisture retentive and commonly used on superficial and partial-thickness wounds (e.g., abrasions, blisters, pressure ulcers) that have minimal drainage. Alginates would be more desirable if the wound was partial or full-thickness with more drainage.

Which of the following is not an indication for applying a wound dressing? protect the area from injury prevent contamination prevent scarring promote healing

prevent scarring The four indications for wound dressings are to physically protect the site of injury, prevent contamination, prevent transmission of infection, and promote healing. Scar tissue is a naturally occurring process that serves to increase tensile strength during the remodeling phase.

Which type of dressing would be the least moisture retentive? alginates semipermeable foams hydrocolloids semipermeable films

semipermeable films Film dressings are thin membranes made from transparent polyurethane with water-resistant adhesives. The dressings are permeable to vapor and oxygen, but are largely impermeable to bacteria and water which makes them retain little moisture.

Which of the following would typically be the dressing of choice to treat a stage 1 or 2 pressure injury? transparent film hydrocolloids calcium alginates wet-to-dry dressings

transparent film Transparent film dressings such as Tegaderm are dressings of choice for stage 1 and 2 pressure injuries with blister formation over bony prominences. This type of dressing should not be used on draining or infected wounds.

Which of the following would be the most appropriate type of wound dressing to place over an intravenous access site? hydrocolloid dressing transparent film dressing non-adherent gauze dressing foam dressing

transparent film dressing Transparent film dressings are semipermeable membrane dressings that are adhesive and waterproof. They are occlusive and serve to diminish the possibility of contamination while allowing visualization of the wound.
