forms the internal involuntary sphincter - guards opening between the urinary bladder and urethra
A
Middle circular layer
3
Q
The middle circular layer of the detrusor muscle is innervated by which NS
A
ANS
4
Q
Which NS:
carries inhibitory impulses to the bladder and motor impulses to the internal sphincter
A
SNS
Detruser muscle to relax and the internal sphincter to constrict, retaining urine in the bladder
5
Q
Which NS:
carries motor impulses to the bladder and inhibitory impulses to the internal sphincter
A
PNS
cause the detrusor muscle to contract and the sphincter to relax

10
Q
What is Micturition
A
the process of urinating; voiding
11
Q
Process of urination- Micturition process
A
detrusor muscle contracts
internal sphincter relaxes → urine enters the posterior urethra
perineum muscles and external sphincter relax
abdominal walls constrict slightly
diaphragm lowers
urination occurs
12
Q
Reflex urination persists until when?
A
until higher nerve centers develop after infancy leading to voluntary control
13
Q

Functions of the skin
Protective barrier against injuries
Prevent loss of moisture
Immune organ - detects infections
Production Vit. D
Temperature regulator
Sensory organ
50
Factors that affect skin
Developmental
Fluid loss
Weight
Nutrition
Diseases
Jaundice
51
Weight factors- skin
Excessively thin & obese persons
MOST susceptible to skin injury
52
Developmental factors- skin
Babies & GERI’s have thin skin - easily injured
as babies age - skin toughens
Skin thins again with age
53
Types of wounds
Intentional-unintentional
Open-closed
Acute/chronic
Partial/full thickness, complex
54
Intentional wound
Result of planned invasive therapy or treatment
Purposefully created for therapeutic purposes
Result from surgery, intravenous therapy, lumbar puncture
-edges are clean and bleeding is usually controlled
-made under sterile conditions with sterile supplies
-risk for infection is decreased and healing is facilitated
55
Unintentional wound
accidents, unexpected trauma, “forcible” injuries
stabbing, gunshot, burns, falls, etc
Result from unsterile environments, contamination is likely
wound edges are typically jagged, Multiple traumas are
common, bleeding is uncontrolled
High risk for infection and longer healing time
56
Open wound
occurs from intentional or unintentional of trauma - can be packed “wet-to-dry”
Skin surface is broken providing a portal of entry for microorganisms
bleeding tissue, damage and increased risk for infection and delayed healing may occur in open wounds
57
Closed wound
A blow, force, or strain
Caused by trauma such as a fall, and assault, or motor vehicle crash
Skin surface not broken
soft tissue is damaged and internal injury and hemorrhage may occur
58
Acute wound
Wound that is expected to progress through phases of normal healing, resulting in wound closure - ex. SURGICAL
59
Chronic wound
Wounds that do not progress through normal, orderly and timely sequence of repair - Often incorrectly treated
60
Contusion
BRUISE caused by blunt instrument causing injury to underlying tissue - over skin intact
61
Abrasion
scraping of top 1-2 layers of epidermis / dermis - skin rubbed away
62
Laceration
caused by a sharp object - no skin is missing
63
Avulsion
Forcible tearing off of skin or other part of the body, such as an ear or finger, likely exposing muscles, tendons and tissue
64
Stage 1 PI
Skin intact, nonblanchable erythema
65
Stage 2 PI
partial thickness skin loss with exposed dermis
66
Stage 3 PI
Full thickness skin loss, subcutaneous layer exposed
67
Stage 4 PI
Full thickness skin and tissue loss, muscle, tendon, ligament, cartilage may be exposed
68
Unstageable PI
Obscured (Covered)full thickness skin and tissue loss. Slough/ eschar (black and dry) cover pressure injury, removal of eschar or slough will reveal the pressure injury at stage 3 or 4 of PI.
69
Principles of wound healing
Primary
Secondary
Tertiary intention
70
Primary intention
Closing a wound with staples, sutures glue, etcetera
71
Secondary intention
granulation - Wounds that cannot be Stitched causing a large amount of tissue loss
72
Tertiary intention
Delayed wound closures that may need draining and other therapies before closing
73
Stages of wound healing
Hemostasis
Inflammatory phase
Proliferation
Maturation
74
Hemostasis phase
-blood vessels constrict - STOPPING BLOOD LOSS
-occurs immediately after initial injury
-blood clotting begins through platelet activation and clustering
75
Inflammatory phase
- follows hemostasis and last about 2 to 3 days
-lymphocytes and macrophages move to the wound
-leukocytes digests bacteria and cellular debris
76
Proliferation phase
- Fibroblastic, regenerative, or connective tissue phase
- last for several weeks
- new tissue is built to fill the wound space through the action of fibroblasts
- collagen is produced 2 create new tissue
77
Maturation phase
- Metro or remodeling begins about three weeks after injury
- continues for months or years
- collagen deposits in the area is remodeled
- healed wound becomes stronger and more like adjacent tissue
78
Local factors that affect healing
Pressure
desiccation (dehydration)
maceration (overhydration)
necrosis
Biofilm - bacterial slime
79
Systemic factors that affect healing
Age, circulation, oxygenation, nutritional status, wound etiology (what cause the wound), medications and health status, immunosuppression (AIDS, lupus, on chemo or other autoimmune disease) and Adherence to Treatment Plan (bad wound takes longer to heal if you don’t stick to your treatment plan)
