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. Bright red, bloody fluid: Bright red fluid indicates fresh blood, which is typically seen in the initial drainage from a surgical site or in cases of active bleeding. This type of drainage is not characteristic of serous fluid and may suggest a complication that requires further assessment.

B. Thick, green fluid: Thick, green fluid often indicates the presence of infection or pus, which would be classified as purulent drainage rather than serous. Serous drainage should not have a thick consistency or a green color, as this would suggest an inflammatory process or infection.

C. Clear, watery fluid with a pale yellow tint: This describes serous drainage, which is typically light in color and has a watery consistency. Serous fluid is a normal finding in the early stages of wound healing, as it contains plasma and does not indicate infection or excessive bleeding.

D. Milky, white fluid: Milky or cloudy fluid can indicate the presence of chyle (lymphatic fluid) or infection, which is not characteristic of serous drainage. Serous fluid should not appear milky, as this would suggest a different underlying issue that may need to be investigated further.

A. A client who is 1 day postoperative and has a nursing assistant helping him out of bed B. An older adult client who is confused and has urinary frequency C. A client with diabetes mellitus who has a leg ulcer D. An adolescent client who has a leg fracture and has been using crutches for the past 2 days

Correct Answer is B

Explanation

A. A client who is 1 day postoperative and has a nursing assistant helping him out of bed: While this client is at risk due to being postoperative, the presence of a nursing assistant provides additional support and assistance, which helps mitigate the risk of falling during this transition.

B. An older adult client who is confused and has urinary frequency: This client is at the greatest risk for a fall. Confusion can impair judgment and coordination, and urinary frequency can lead to hurried movements to the bathroom, increasing the likelihood of falls. Older adults are generally more susceptible to falls due to physiological changes, and the combination of confusion and the need for frequent trips to the bathroom heightens this risk significantly.

C. A client with diabetes mellitus who has a leg ulcer: Although this client may have mobility issues related to the leg ulcer, diabetes does not inherently increase the risk for falls as much as confusion and urinary frequency do. The focus would be on wound care rather than immediate fall risk.

D. An adolescent client who has a leg fracture and has been using crutches for the past 2 days: While this client is at risk due to the leg fracture and the use of crutches, they are likely to have received instruction on proper use of the crutches. If the client is following these instructions, the risk may not be as high as that of the confused older adult.
