Study Notes
Level of Consciousness (LOC)
- LOC is a key assessment for evaluating a patient's alertness and cognitive response.
- Categorized into alert, lethargic, obtunded, stuporous, and comatose states.
- The Glasgow Coma Scale (GCS) evaluates LOC based on eye-opening, verbal response, and motor response.
Extremities Assessment
- Involves assessing circulation, motion, and sensation in hands and feet.
- Normal findings include warm, dry skin, full range of motion, and symmetrical muscle strength.
- Abnormal findings may show cold extremities, weak pulses, or loss of sensation, indicating potential circulation issues.
Digital Clubbing
- Clubbing is the thickening of fingers and nails, often indicating chronic hypoxia.
- Common conditions leading to clubbing include COPD, lung cancer, and congenital heart diseases.
Capillary Refill
- A test for assessing peripheral perfusion by pressing on the nail bed and measuring time for color return.
- Normal capillary refill time is less than 2 seconds, while delayed refill (over 2 seconds) can indicate shock or peripheral vascular disease.
Pedal Edema
- Swelling in lower extremities, often a result of heart failure or venous insufficiency.
- Graded from +1 to +4 based on depth and persistence of pitting after pressure application.
Conditions That Cause Abnormal Assessment
- Heart failure can lead to pedal edema and jugular venous distention (JVD).
- Lung diseases such as COPD or pneumonia may cause digital clubbing, altered tactile fremitus, or abnormal percussion findings.
Tactile Fremitus
- A chest wall vibration felt during speech, often assessed with "99."
- Increased fremitus may indicate lung consolidation (e.g., pneumonia), while decreased fremitus may result from pneumothorax or pleural effusion.
Subcutaneous Emphysema
- Condition characterized by trapped air under the skin, commonly due to trauma or chest tubes.
- Present as a crackling sensation when pressing the skin, resembling bubble wrap.
Percussion
- Normal percussion results in a resonant sound, indicating air-filled lungs.
- Dullness suggests fluid or solid tissue, often seen in pleural effusion or pneumonia.
- Hyperresonance indicates overinflation of lungs, as in emphysema or pneumothorax.
Spinal and Chest Abnormalities
- Kyphosis refers to abnormal forward spine curvature, affecting respiratory function in elderly patients.
- Scoliosis involves a lateral curvature of the spine, potentially compromising lung function.
Jugular Venous Distention (JVD)
- Increased venous pressure in the neck that is prominent in right-sided heart failure.
- Assessment performed with the patient elevated at a 45-degree angle; distended veins indicate higher central venous pressure.
Chest Expansion
- Normal chest expansion should be equal on both sides during inspiration.
- Unequal expansion indicates possible conditions like pneumothorax, pleural effusion, or lung collapse.
Anterior-Posterior (A/P) Diameter
- Normal chest width to depth ratio is about 2:1.
- In conditions like emphysema, a barrel chest appearance with a 1:1 ratio suggests hyperinflation.
Tracheal Deviation
- The trachea shifts towards the affected side in atelectasis or lung collapse.
- It moves away from the affected side in conditions like tension pneumothorax or large pleural effusion.
