Geriatrics (1305) Flashcards
General age when signs of aging starts to accelerate?
65
Respiratory changes when you age?
- Chest wall becomes more rigid and accessory muscles weaken (reduced pulmonary capacity)
- Loss of cilia, dampened cough reflex and impaired gag reflex (increases risk of aspiration)
Cardiovascular changes when aging?
- Increase in cholesterol deposits, thickening of arteries (more prone to MI/HTN)
- Arrhythmias (a-fib most common)
- Increase in afterload which decreases cardiac output; more prone to CHF
Renal system changes when aging?
- Renal blood flow declines which decreases renal function
- Causes fluid retention which results in peripheral edema
- Severe renal disease can lead to hyperkalemia and cardiac arrest
CNS when aging?
- Atrophy of brain tissue “shrinkage”
- Blood vessels become harder; more prone to occlusions
- Decrease in pain receptor sensitivity; pain threshold becomes higher
- Balance becomes impaired
Muskuloskeletal changes when aging?
- Bones become weaker, usually secondary to:
a) Osteoporosis (thinning of bone)
b) Osteoarthritis (joint degeneration)
Common medical conditions in elderly population?
- MI/Arrhythmia
- CHF/COPD/Pneumonia/PE
- UTI
- Diabetes
- Arthritis/osteoarthritis
- GI disturbances/bleeds
- CVA
What should you do if you see depression in leads V1-V3?
15 lead
Common medications for A-fib?
Eliquis, Xarelto, Pradaxa, Coumadin
Left Ventricular Heart Failure?
When LV fails to be a pump
- Causes backflow into pulmonary circulation causing pulmonary edema
- Can present as blood tinged sputum
Right Ventricular Heart Failure?
- Can result from LVF but also pulmonary hypertension
- Causes back pressure into venous system causing peripheral edema
Pulmonary Edema?
- Can be cardiogenic from CHF
- Can be non-cardiongenic from drowning, ARDS, PE, etc
- Use CPAP for both, no nitro for non-cardiogenic
What is Pneumonia?
Lung infections that can be bacterial, viral, or fungal
- Associated with fever and pleuritic chest pain (sharp pain with movement or deep inspiration)
- Can be unilateral or bilateral (course on auscultation)
- Can also present with wheezing
What is Pulmonary Embolism?
Blockage of pulmonary artery
- Clot often occurs in lower legs (DVT) and breaks off travelling into heart, out of RV, and into pulmonary circulation
- Pts will have: dyspnea, cough, anxiety, tachycardia, low O2 sats
- Birth control and smoking is a common risk factor in young patients
