Deck 29: Wound Healing and Hemostasis

Question 1

The two main skin layers above the subcutaneous layers are called:

A) glabrous and hairy
B) epidermis and dermis
C) fascia and epidermis
D) adipose and fascia

Answer 1

B
The two main layers of the skin above the subcutaneous layers are the dermis and epidermis.

Question 2

The hemostatic scalpel uses argon gas to provide rapid hemostasis by monopolar coagulation.

Answer 2

False
The disposable blade,size No.10,11,or 15,has a heating and sensing microcircuitry between the steel and a layer of copper coated with electrical insulation and a nonstick surface.The argon beam coagulator uses argon gas in combination with an ESU pencil to effectively deliver radiofrequency energy to tissue in a coaxial,noncontact,white-light beam for the purpose of rapid hemostasis by monopolar coagulation.

Question 3

What is not an influence on the ease with which a skin incision is made?

A) Type of knife handle
B) Size of the knife blade
C) Toughness of skin or scar tissue
D) Thickness of subcutaneous tissue

Answer 3

A
The following affect how easily a skin incision is made: sharpness,shape,and size of the knife blade;resistance of self-adhering plastic drapes;toughness of skin;and thickness of subcutaneous tissue.

Question 4

It is a safe practice to make a longer incision than needed to allow room to retract the necessary organs and vessels to control bleeding.

Question 5

Radiopaque sponges are not to be used as part of the dressing.

Question 6

Tissue along the incision reaches its greatest strength in about 7 to 15 days.

Question 7

Never cover the entire incision with a dressing,because the air will keep it dry and prevent bacteria from forming.

Question 8

Hypothermia increases cellular metabolism as the body attempts to increase its warmth during a surgical procedure.

A ____is a large growth that extends beyond the border of a scar.

A) hematoma
B) cicatrix

A) Third intention
B) First intention
C) Second intention
D) Non-intention

Question 15

A) Keep the end of the drain sterile until connected to the drainage tubing.
B) Keep only the drain and the top half of the tubing sterile.
C) Wrap tape around tubing connections to secure them.
D) Dress the drain site together with the incision site.

Question 16

Wound disruption is characterized by which of the following symptoms?

A) Bradycardia
B) Abnormal discharge and change in the contour of the wound
C) Increased bowel gas pressure
D) Increased blood pressure

Question 17

____ is characterized by swelling between fascial layers in any plane of the body.

A) Incisional infection
B) Compartment syndrome
C) Necrotizing fasciitis
D) Keloid

Question 18

What are the benefits of early ambulation?

A) Increased gas pain
B) Improved circulation
C) Increased gastroparesis
D) Decreased wound pain

Question 19

What layer below the dermis supports the muscle?

A) Sebaceous glands
B) Subcutaneous striated muscle
C) Fascia
D) Epidermis

Question 20

What type of dressing facilitates new tissue growth and is commonly used on burn wounds?

A) To insert tube feeding contents
B) To insert air into esophagus
C) To aspirate stomach contents
D) To cauterize bleeding in stomach

Question 25
