Q

Cardiovascular Chnages

A
  • Arteriosclerosis: stiffening of vessel walls
  • Increase blood pressure leads to over production of abnormal collagen and elastin which contribute to vascular stiffness
  • Alrtic Sclerosis: aortic valve thickens due to fibrosis and calcification
  • Aortic Stenosis: aortic valve does not open fully, decreasing blood flow from the heart
  • A fib and flutter common due to the wear of the primary pacemaker of the heart

Q

Delrium

A

“Acute brain syndrome”
Characterized by Disorganized thoughts, inattention, memory loss, disorientation, hallucinations, delusion
-experiences rapid alteration between mental statuses such as lethargy, agitation, disorganized thinking, changes in perception
-Frequent causes: infection, glucose, medications, temperature
-DELERIUMS : Drugs, Emotional, Low Pa02, Infection, Retention, Ictal, undernutrition, metabolism, subdural hematoma

Q

Dementia

Study These Flashcards
A

Produces irreversible brain failure

  • Signs symptoms: shortened attention, talking nonsense, hallucinations, confusion, disoreintation, personality changes
  • Causes : infections, strokes, head injuries, poor nutrition, and medications
  • Most common types = Alzheimer’s and multi infarct
  • Progressive loss of cognitive function, impairments of memory, visual perception, and cognitive skills
22
Q

Alzheimer’s Disease

Study These Flashcards
A

Most common type of dementia

  • begins with subtle symtpoms such as losing items, forgetting people’s names
  • African Americans and latinos are more prone to disease
  • MCI: mild cognitive impairment- early stage of Alzheimer’s
  • Later stages involve sundowners, difficulty reading and writing
  • not a normal part of aging
23
Q

Parkinson’s Disease

Study These Flashcards
A

Age related neurological disorder with two or more symptoms

  • resting tremor, slowness of movement, ridgidity, or stiffness of extremities or trunk
  • caused by degeneration of the substantia nigra, an area of brain that controls voluntary movement by producing neurotransmitter dopamine. Dopamine is used by cells to transmit impulses, so loss of dopamine causes loss of motor function
  • can affect one or both sides of body
24
Q

Bowel Obstruction

Study These Flashcards
A

Large Bowel Obstruction- likely caused by cancer, impacted stool, or sigmoid volvulus
Small Bowel Obstruction- commonly due to gallstones
-nearly 1/3 of elderly people have gallstones
-with one or more instances of cholecystitis, the gallbladder adheres to the small bowel and, over time, creates and opening, or fistula. The stone then drops into the Bowel and produces an obstruction.

25
Biliary Disease
Includes cirrhosis, hepatitis, cholecystitis, | -Signs and symptoms: jaundice, fever, RUQ pain, vomiting/nausea
26
Peptic Ulcer Diesease
Chronic use of NSAIDS social factors, high stress professions can cause ulcers -stomach pain goes away when eating but comes back later
27
GI Bleed
Decreased rates of peristalsis increase the likelihood that irritating substances will damage gastric lining - Bloody stool usually is indicative of bleeding from the lower GI - Blood from stomach is dark and tarry - Briht Red in stool usually comes from rectum or large intestine
28
Urinary Tract Infections
Most common hospital infection to cause sepsis Usually develop in lower urinary tract (urethra and bladder) -Signs and Symptoms: fever, SOB, GI symtpoms, poor urinary output, hematuria
29
Incontinence
As age increases, the capacity of the bladder and strength of the Sphincter muscles decreases. - Pressure on urinary Sphincter is responsible for triggering recognition of the need to urinate, a decrease in Sphincter tone may keep older people from realizing that their bladder is full until they can no longer hold it. - Stress incontinence: occurs during activities such as laughing, coughing, lifting and exercise - Urge incontinence: triggered by hot or cold fluids, running water, and thinking about urination
30
Diabetics
More prone to hyperglycemia hyperosmolar nonketoic coma (HHNC) Hyperosmolarity and hyperglycemia lead to osmotic dieresis and osmotic shift of fluid to vascular space, resulting in further intracellular dehydration. -Signs and Symptoms: dizziness, confusion, AMS, polydipsia -most frequent cause of a HHNC is INFECTION. Others are hypo/hyperthermia, strokes, cardiac disease, pancreatitis - >500mg/dl sugar and has acute dehydration and confusion -Normal BGL is between 70-120 less than 45 is hypoglycemic
31
Thyroid Disorders
Acute onset of hyperthyroidism (thyrotoxicosis) is tachycardia, tremor, anxiety, hyperactive reflexes -Atrial Fibrilation is likely to be induced by an overactive thyroid gland in a geriatric patient
32
Sepsis
``` Oral temp >100.4 or <96.8 Fahrenheit >20 resp/min Capnography < 32mmHg HR > 90/min TEMP BREATH HEART RATE CAPNOGRAPHY ```
33
Polypharmacy
Multiple drugs are needed to treat multiple medical conditions
34
Herpes Zoster
Shingles virus | Caused by reactivation of varicella virus in Nerve roots
35
Cellulitis
Inflammationin skin caused by a bacterial infection | Symptoms: fever, chills, malaise, warmth, swelling, redness, tenderness
36
Pressure Ulcer
Occur when pressure is applied to body tissue, resulting in lack of perfusion and ultimately necrosis
37
Rheumatoid Arthritis
Long term autoimmune disorder classified by inflammation of the joints and surrounding tissues
38
Osteoporosis
Decrease in bone mass leading to reduction in bone strength and greater susceptibility of fracture - Type 1 : radius and hip fractures - Type 2 : hip and vertebral fractures
39
Geriatric Traumas
Most are from falls or MVA
40
Post Fall Syndrome
Geriatrics develop lack of confidence, anxiety about potential falls
41
Extrinsic Causes
External such as tripping, slipping
42
Intrinsic Causes
Dizzy or syncopal episode
43
MVA's
Second leading cause of death for geriatrics
44
Head Trauma
Increased fragility of blood vessels, enlargement of subdural space and decreased in supportive tissue of the meninges contribute to more vulnerability
45
Spondylosis
Degenerative changes in spine causes arthritic "spurs" or narrowing of vertebral canal
46
Chest Injuries
More likely for flail chest or rib fracture due to stiffening and brittleness of the chest wall
47
Abdominal Injury
Produces injury to the liver due to less protection by abdominal muscles
48
Burns
Immune system depressed to fight infection, and fluid replacement is complicated due to renal insufficiency
49
Hypothermia
Internal regulation is slowed Body's ability to recognize fluctuations in temperature becomes delayed due to slow Endocrine system Heat gain or less due to environemental changes is delayed by atherosclerotic vessels, slowed circulation, and decreased sweat production in the skin.
50
DNR
You can treat various disorders,administer medications and perform treatments. You can NOT provide artificial ventilations or cardiovascular assistance.
51
Hospice
Provides terminal care for patients and supports for their families
