Which of the following is a benefit of negative pressure wound therapy (NPWT) for skin wounds?
Prevents scarring by minimizing collagen production
Relieves pain by numbing the wound area
Promotes wound healing by increasing blood flow to the wound
Reduces the risk of infection by creating a sterile environment
The Correct Answer is C
A. Prevents scarring by minimizing collagen production: Negative pressure wound therapy (NPWT) does not prevent scarring by minimizing collagen production. In fact, NPWT can stimulate collagen production as part of the wound healing process, which can contribute to scar formation.
B. Relieves pain by numbing the wound area: NPWT does not have a numbing effect on the wound area. While it may help promote a more comfortable healing environment, it does not directly relieve pain like local anesthetics or analgesics would.
C. Promotes wound healing by increasing blood flow to the wound: NPWT promotes wound healing by creating a negative pressure environment that helps draw excess fluid away from the wound, reduces edema, and stimulates blood flow to the area. This increased blood flow enhances the delivery of nutrients and oxygen necessary for the healing process, making this option correct.
D. Reduces the risk of infection by creating a sterile environment: While NPWT can help reduce the risk of infection by keeping the wound moist and removing excess exudate, it does not create a completely sterile environment. Proper wound care and dressing changes are still necessary to maintain cleanliness and prevent infection.

Correct Answer is D
Explanation
A. "I will keep my walker at the end of my bed.": Storing a walker at the end of the bed may not be the safest option. The walker should be kept within easy reach to ensure the client can access it promptly when getting up, reducing the risk of falls.
B. "I will place an area rug at the entry of my bathroom.": Placing an area rug in a high-traffic area like the bathroom can create a tripping hazard, increasing the risk of falls. It is important to keep walking paths clear and free from obstacles to ensure safety.
C. "I will keep the fluorescent ceiling light in my room at night.": While having adequate lighting is important, keeping the light on at night may not address the need for easy access to light sources. The client should consider using nightlights or ensuring that light switches are easily accessible to avoid navigating in the dark.
D. "I will place a bath seat in my shower to use when I bathe.": This statement indicates an understanding of safety measures to prevent falls while bathing. Using a bath seat can provide stability and allow the client to bathe safely while reducing the risk of slipping or losing balance in the shower. This reflects the client's awareness of their needs related to fall prevention.
Correct Answer is D
Explanation
A. Airborne: Airborne precautions are used for diseases that can be transmitted through airborne droplet nuclei, such as tuberculosis or measles. Hepatitis C is not transmitted through the air, making airborne precautions unnecessary for this condition.
B. Droplet: Droplet precautions are required for infections spread through respiratory droplets, such as influenza or meningitis. Hepatitis C is not spread via respiratory droplets, so droplet precautions are not applicable.
C. Contact: Contact precautions are necessary for infections that can be transmitted through direct contact with the patient or contaminated surfaces, such as MRSA or C. difficile. While contact precautions may be applied in specific situations involving hepatitis C, they are not the standard precautions for routine care of hepatitis C patients.
D. Standard: Standard precautions are the foundation for infection control practices and are recommended for all patients, regardless of their diagnosis. This includes measures such as hand hygiene, using personal protective equipment (PPE) when necessary, and safe handling of potentially contaminated materials. Since hepatitis C is primarily transmitted through blood and body fluids, standard precautions are appropriate for caring for clients with this condition.
