Question 1

Repair and regeneration have several important differences. One of the differences is that repair occurs in tissues that were made up of ________ , whereas regeneration occurs in tissues made up of __________.

Answer 1

1. permanent cells 2. labile or stable cells

Question 2

Answer 2

Type 1

Question 3

______ collagen is located in cartilage.

Answer 3

Type II

Question 4

Answer 4

Type III

Question 5

_____ collagen is located in basement membranes

Question 6

Wound healing contraction starts ______ days post wound, and eventually contracts up to ____ of the wound area.

Answer 6

1. 2-3 days 2. 70%

Question 7

What are the phases of wound healing and what are there approximate timeframes.

Answer 7

1. Inflammation Phase: acute phase lasting only a few days
2. Proliferative Phase: begins 48 hours after injury
   3.Maturation Phase: can last up to two years

Question 8

The goal of the maturation phase of wound healing is to increase the tensile strength of the scar. It is important to realize that a scar is only about _____ of the strength of originally intact skin.

Answer 8

1. 80%

Question 9

When is the proliferative phase of wound healing is complete?

Answer 9

when the wound is 100% resurfaced

Question 10

What are the differences between healing with primary and secondary intention ?

Answer 10

In primary intention the cut is typically clean and sutured
In secondary intention wound with seperated edges which typically takes much longer during healing

Question 11

What are the local and systemic factors that can influence healing ?

Answer 11

Local: type, size of the wound, the location of the wound, adequacy of vascular supply, temperature, and moisture

Systemic: circulatory and metabolic status, infection, diabetes, neoplasia, and nutritional levels

Question 12

What are the differences between arterial and venous insufficiency ?

Answer 12

arterial insuffiency: punched out shape, pale granulation, deep, dry, loss of hair

venous insufficiency: irregular shape, red wound bed, shallow, copious,]

Question 13

Decreased circulation from pressure leads to ulceration. This is typically caused by unrelieved pressure generally found over bony prominences. These wounds are staged according to the depth of tissue damage. The above characteristics describe which type of wound?

Answer 13

pressure ulcers

Question 14

What are the differences between keloid scars and hypertrophic scars ?

Answer 14

Keloid Scars: growth of a scar beyond the confines of the original wound
Hypertrophic Scarring: scar stays within the confines of wound, often seen in burns

Question 15

What kind of cells are in the kidneys, lungs, and liver, and which kind are in the heart ?

Answer 15

1. stable cells 2. permanent cells

Question 16

What kind of cells constitute the PNS and how fast do axons grow ?

Answer 16

permanent cells, 1mm/day or 1 inch/month

Question 17

(T/F ) Rupture of muscles, as well as ruptures of tendons and ligaments, require surgical approximation followed by a period of immobilization for appropriate repair to occur.

Answer 17

True

Question 18

What are the three layers of the skin

Answer 18

Epidermis, Dermis, and Subcutaneous fat

Question 19

The renewal of the epidermis under normal conditions occurs every:

Answer 19

15-30 days

Question 20

In which layer is hair, sebaceous glands, and sweat glands found in ?

Answer 20

dermis

When talking about skin neoplasms what does the acronym ABCD stand for ?

Answer 21

A: Asymmetry
B: Border
C: Color
D: Diameter

Question 22

Which type of skin cancer is the most common malignant neoplasm found and rarely metastasizes?

Answer 22

basal cell carcinoma

Question 23

Which kind of skin cancer is the second most common malignant neoplasm found and has a low propensity to metastasize (< 2%).

Answer 23

squamous cell carcinoma

Question 24

To what can most types of skin cancers be attributed to ?

Answer 24

overexposure to the sun

Question 25

(T/F) To be well equipped to assist patients in mobility tasks, you must have a basic understanding of the rules that govern movement.

Answer 25

True

Question 26

In patient-care techniques, your _______ becomes the most essential instrument you have for performing tasks and achieving functional goals. To use your body effectively to achieve patient mobility while protecting yourself against injury, and to educate patients in the safe and effective use of their bodies, the clinician must have a fundamental understanding of certain laws of ________ .

Answer 26

body, physics

Question 27

_____ _________ refers to the way in which we position our bodies during tasks.

Answer 27

body mechanics

Question 28

What is the difference between mobility and stability ?

Answer 28

Mobility: how well something can move
Stability: how well something can stay put

Question 29

he contact area of an object with its supporting surface is called the _____

Answer 29

Base of support ( BoS)

Question 30

Stability is promoted when:

Answer 30

1. The BoS is greater in area
2. The line of gravity (LoG), that is, gravity’s line of action acting on the object’s CoM, is at or nearer the center of the BoS
   3.the distance between the CoM and the BoS is shortened and the CoM is lower and closer to the BoS

Question 31

Mobility is promoted when:

Answer 31

1. the BoS is smaller in area
2. The LoG is allowed to move beyond the center of the BoS
3. The distance of the CoM above the BoS is greater
