common concerns in old ppl?
- substance abuse, overmedication, loss of mental acuity (cognitive impairment), depression, urinary incontience, sensory isolation bc visial and/or hearing impairmentand nutritional problems from signficant life stresses like financial hardship, relocation, loss of normal roles in life, death of loved ones and friends, skyrocketing heatlhcare costs and medical insurance premiums
- regular exercise 3-5x wkly, proper nutrition and hazard free environment to prevent falls should be maintained
each year __ in __ ages 65 and over falls, causing moderate to severe injuries.
1 to 3
meds and aging?
- older ppl take lots of drugs + OTC drugs so combos = high risk for adverse drug reactions
- old ppl r often given intestinal probiotics to ward off antibiotic-associated diarrhea infection w/ Clostridoides difficile
- some older adults can’t handle standard dose of meds bc metabolic and body comp changes (increased adipose tissue, decreased total body water, so on)
What are some psychological factors that affect health?
-psych evalencompasses observation of behavior, appearance, mood, communication, judgement, thought processes
- illness change pt + family life such as disrupting daily activities, altered body image, emotional and social changes
- chronic disease is a stressor that can affect person’s self-esteem and behavior bc feelings of fear, helplessness and lack of control occur as well as stages of anxiety, shock, denial, anger, withdrawal and depression
Diagnosis steps?
- Individual seeks medical attention
- guidelines applied for telephone/pt screening determine urgency
- obtain med history (family history, social and occupational history, risk factors, drug allergies, present therapy + meds, onset of s/s)
- physical exam (vital signs, o2 saturation, review of organ system, inspection, auscultation, palpation, percussion)
- diagnostic studies and lab tests (complete blood analysis, urine studies, microscopic exam, chem analysis, radiographic studies, body scans, endoscopy, ultrasonography)
- compare with normal findings
- integrate and interpret
8.formulate diagnosis, treatment plan, prognosis and prevention - provide pt teaching needed info and make appropriate referrals
What is blood analysis
Complete blood count

eryrthrocyte sedimentaiton rate (ESR)
Glucose tolerance (GTT) - fasting blood glucose levels
toxicology studies
drug levels
arterial blood gas (ABG) analysis
cardiac enzymes
cross reaction protein
What r chemistires in blood analysis?
Normal chemistry profiles may contain blood serum levels for:
- albumin
- alkalin phospahtease
- aspartate aminotransferase (AST)
- bilirubin
- calcium creatinine
- lactate dehydrogenase (LD)
- phosphorus
- total protein
- urea nitrogen
- uric acid
what is CBC?
(CBC) for RBC, RBC indices, WBC, WBC differntial, Hgb, hematocrit (HCT) (percentages of RVCs in volume of whole blood), platelet, aka hemogram
What is clotting and coagulation studies?
- partial thromboplastin time (PTT), prothrombin time (PT), platelet (thrombocyte) count and bleeding times
What is erythrocyre sedimentation (ESR)?
rate at which RBCs fall out of well-mixed whole blood to bottom of test tube
What is a drug level test test for?
0 digoxin
- digitoxin
- theophylline
- lidocaine
- lithium
What is Arterial blood gas (ABG) analysis?
- measurement of dissolved oxygen and carbon dioxide in arterial blood
- also measures pH and O2 saturation of arterial blood
What is a cardiac enzyme test?
tests for creatine kinase (CK), CK isoenzymes, LD, LD isoenzymes, AST (serum glutamic oxaloacetic transaminase (SGOT)), aline aminotransferase (ALT, serum glutamic pyruvate transaminase (SCPT__
What are urine studies?
- Urinarlysis (study urine specimen and measure pH, specific gravity, presence of ketones, protein, sugars, bilirbiubin, urobilinogen, color, odor, presence of abn blood cells, cast, bacteria, otehr cells and crystals))
- culture and sensitivty (C&S) of urine (cult - sample of urine specimen is placed in/on culture medium to see whether microbial growth- if growht than identification of pathogenic microbe is determines, sensitivity is when portion of specimen is placed on sensitivty disk (impregnated w/ specific antibiotics) to determine which antibiotics pathogen is resposneive to and resistant to)
What are cardiology tests?
ECG - record of electrical activity of myocardium used to diagnose ischemia, arrhythmias, conduction difficulties, activity of cardiac meds
Echocardiography - ultrasound exam of cardiac structure to define size, shape, thickness, position and movement
holter monitor - miniature ECG that record electrical activity for 24-48 w/ pt recording all activity during time
thallium scan - indicate myocardial profusion and location + extent of myocardial ischemia and/or infarction
Multigated acquisition (MUGA) scan: assesses function of left ventricle and identifies abn of myocardial walls
Stress testing, treadmill and exercise tolerance testing - assessment of cardiac function during moderate exercise
pulse oximeter: spectrophotometer provides noninvasive measurement of O2
cardiac catheterization: Fluoropscopic visualisation of R or L side of hearth by passing a catheter into R or L chamber and injecting dye (angiography consists of catheter being passed into coronary vesselss where dye is injected and fluoroscopic images r recorded)
What are imaging studies?
- radiography: visualization of internal organs and strucutres by EM radiation (contrast medium for soft tissue and some organs like gallbladder, esophagus, stomach and S and L intestines)
- MRI: Magnetic field to visualize internal tissue to view them in 3D manner to determine blood flow, condiiton of bv, tumor and infection detection and differntiatiing healthy and diseased tissue
- CT: use scanning sstem to provide internal strucutre of tissue and organs both geographically and characteristically
- PET: use small amt of radioactive material to produce 3D colored image to show how body tissue and organs function
- Fluroscopy: continous visualization of area undergoing radiographu to study function of tissues and ogans
- sonography, ultrasonography, echography: beam of sound waves projected into target tissue or organs and bouncing back = outline of structure
- myelography: exam spinal cord and spinal nerve roots using dye and/or air into subarchnoid space and record on radiographic film
