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

Answer and Explanation

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 C

Explanation

A. Wear sterile gloves: Sterile gloves are not necessary for checking a pulse. Sterile gloves are typically used for procedures that involve direct contact with sterile areas or instruments. Checking a pulse does not require maintaining a sterile field, so clean gloves are sufficient.

B. Wear an N95 respirator mask: An N95 respirator mask is typically required for airborne precautions, such as those used for tuberculosis, but not for MRSA. MRSA is primarily transmitted through direct contact with infected wounds or contaminated surfaces, so an N95 mask is not needed for this situation.

C. Wear clean gloves: Wearing clean gloves is the appropriate action when interacting with a client who has MRSA. This helps to prevent the transmission of bacteria and protects both the client and the nurse. Clean gloves should be used for any contact with the client or their environment to minimize the risk of spreading infection.

D. Wear protective eyewear: Protective eyewear is generally used when there is a risk of splashes or sprays of bodily fluids. In this scenario, unless there is a specific risk of such exposure during the pulse check, protective eyewear is not necessary. Clean gloves are the primary requirement for basic contact precautions with MRSA.

A. Airborne B. Droplet C. Contact D. Standard

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.
