In a clinical setting, a patient with a chronic wound is scheduled for debridement. Which of the following is the primary purpose of wound debridement?

To increase blood flow to the wound site

To remove necrotic tissue to promote healing

To apply antibiotics directly to the wound

To prevent scar formation

Answer and Explanation

The Correct Answer is B

A. To increase blood flow to the wound site: While debridement may indirectly help improve blood flow by removing barriers to healing, its primary purpose is not to increase blood flow. Increased blood flow is a result of improved wound bed conditions rather than the main goal of the procedure.

B. To remove necrotic tissue to promote healing: The primary purpose of wound debridement is to remove necrotic (dead) or devitalized tissue from the wound bed. This process promotes healing by creating a clean wound environment, facilitating granulation tissue formation, and reducing the risk of infection, making this option the most accurate.

C. To apply antibiotics directly to the wound: While antibiotics may be part of the overall wound care plan, debridement itself is not intended for the direct application of antibiotics. The focus is on removing non-viable tissue rather than applying medications during the procedure.

D. To prevent scar formation: While proper wound care, including debridement, can help improve healing outcomes and potentially minimize scarring, the primary aim of debridement is not to prevent scars. Scarring is influenced by multiple factors, including the type of wound, depth, and individual healing responses.

Correct Answer is A

Explanation

A. "I will wear gloves and a gown when bathing a client who has open skin lesions.": This statement indicates an understanding of the appropriate use of personal protective equipment (PPE) in a situation where there is a risk of exposure to blood or bodily fluids. Wearing gloves and a gown helps protect the AP from potential pathogens present in the client's open skin lesions.

B. "I will wear gloves when measuring a client's blood pressure.": While it may be appropriate to wear gloves for certain procedures, it is not universally required to wear gloves when measuring blood pressure unless there are specific concerns about contamination or exposure to body fluids. This statement does not demonstrate a clear understanding of when gloves are necessary.

C. "I will wear gloves whenever I am in contact with clients.": This statement suggests a lack of understanding of the appropriate use of gloves. Gloves should be used when there is a risk of contact with blood, body fluids, or open wounds, but they are not necessary for all interactions with clients, especially if there is no risk of contamination.

D. "I will wear gloves to minimize the number of times I have to wash my hands.": This statement indicates a misunderstanding of the primary purpose of gloves. Gloves are used to protect both the caregiver and the client from infection, and hand hygiene should still be performed before and after glove use. The focus should be on infection control rather than convenience.

A. Partial thromboplastin time (PTT) 65 seconds B. Hematocrit 45% C. White blood cell count 8.000/mm3 D. Platelets

Correct Answer is A

Explanation

A. Partial thromboplastin time (PTT) 65 seconds: The normal PTT range is typically between 25 to 35 seconds for patients not on anticoagulants. For a patient receiving heparin therapy, the therapeutic PTT range is usually 1.5 to 2.5 times the normal value, which translates to approximately 60 to 100 seconds. A PTT of 65 seconds is at the lower end of the therapeutic range and may require adjustment in dosage or closer monitoring, especially if there are concerns about achieving adequate anticoagulation for the treatment of a pulmonary embolism. It is important to report this value to the provider.

B. Hematocrit 45%: A hematocrit of 45% is within the normal range for adult females (38% to 47%) and males (40% to 54%). This value does not indicate any immediate concern related to heparin therapy or the treatment of a pulmonary embolism.

C. White blood cell count 8.000/mm³: A white blood cell count of 8,000/mm³ is within the normal range (4,500 to 11,000/mm³) and does not indicate any infection or inflammatory process that requires immediate reporting.

D. Platelets: The specific platelet count value is not provided. However, heparin therapy can lead to thrombocytopenia (low platelet count), so if the platelet count is below 150,000/mm³, it should be reported to the provider. Without the specific value, it is not possible to determine if this requires reporting.
