Other systems weak points

Question 1

Function of the dermis

Answer 1

regulate temperature and supply blood to the epidermis

Question 2

Dermis contains

Answer 2

blood vessels, nerve endings, hair follicles, Pacinian corpuscles, sweat glands, sebaceous glands

Question 3

Hypodermis consists of

Answer 3

adipose tissue and collagen

Question 4

Hypodermis functions as

Answer 4

insulator and shock absorber for internal organs

Question 5

Location and function of Merkel cells

Answer 5

epidermis
light touch

Question 6

Nerve endings are primarily located where?

Answer 6

dermis
can also be in hypodermis

Question 7

Pacinian corpuscles are nerve receptors located in and function?

Answer 7

dermis
deep pressure and vibration

Question 8

Phases of wound healing:
Inflammatory Phase lasts how long?
Proliferative Phase lasts how long?
Maturation Phase lasts how long?

Answer 8

1-10 days
3-21 days
7 days -2 years

Question 9

Inflammation that persists chronically for weeks and months interferes with

Answer 9

initiation of proliferative phase processes and increases risk of infection

Question 10

Immature scar vs mature scar

Answer 10

red, raised, and rigid
pale, flat and pliable

Question 11

Hypertrophic scarring with burn injuries

Answer 11

can significantly impact maturation phase progression.

Question 12

Burn without hypertrophic scarring will mature within

Answer 12

4-8 weeks

Question 13

Burns with hypertrophic scarring mature in

Answer 13

2 years

Question 14

Primary intention healing

Answer 14

acute wounds with minimal tissue loss.
smooth clean edges that are closed with sutures, staples or adhesives.
examples: surgical incision, laceration, puncture, superficial and partial-thickness burns

Question 15

Secondary Intention healing

Answer 15

permits wound to be closed on their own without superficial closure.

Question 16

Wounds that heal by secondary intention?

Answer 16

with characteristics such as significant tissue loss or necrosis, irregular or nonviable wound margins that cannot be reapproximated, infection or debris contamination.
Associated with pathology: diabetes, ischemic conditions, pressure damage or inflammatory disease.

Question 17

Wounds healing by secondary intention require..

Answer 17

ongoing wound care
larger scars

Question 18

Examples of wounds that heal by secondary intention

Answer 18

neuropathic
arterial
venous
pressure ulcers
most full-thickness wounds
chronically inflamed wounds

Question 19

Tertiary Intention healing

Answer 19

delayed primary intention
wounds at risk for developing complications such as sepsis or dehiscence may be temporarily left open. Once risk factors are alleviated then wound can be closed by primary intention

Question 20

Medications that can negatively impact wound healing

Answer 20

anti-inflammatory
immunosuppressive
anti-coagulant
anti-neoplastic
steroid
oral contraceptives

Question 21

Contamination

Answer 21

presence of non-replicating bacteria on a wound that causes no additional tissue injury and does not stimulate an inflammatory immune response

Question 22

Colonization

Answer 22

replicating bacteria on a wound that does not invade or further injure tissues and does not stimulate inflammatory response. It can delay wound healing.
They benefit wound healing by preventing more virulent organisms from proliferating in wound bed.

Question 23

Infection

Answer 23

replicating bacteria that invades viable tissue beyond wound surface causing a visible inflammatory respond. Significantly delays wound healing. Can progress to sepsis, osteomyelitis and gangrene.
