Study Notes

Assessment of Edema

Edema is the accumulation of fluid over dermal vessels, commonly found in periorbital, arm, hand, sacrum, pre-tibial, ankle, and pedal areas.
Assess symmetry and extent by measuring circumference and determining vertical spread up the limb.
Pitting edema characterized by an indentation left by pressure, measured as follows:
- 1+: 0-2 mm (trace to mild, disappears quickly)
- 2+: 2-4 mm (mild to moderate, lasts 10-15 seconds)
- 3+: 4-6 mm (moderate to severe, can last up to a minute)
- 4+: 8 mm+ (severe, can last several minutes)

Cardiac Assessment: Older Adults

PMI (Point of Maximum Impulse) may be difficult to palpate due to increased chest diameter.
Heart sounds can be muffled from excess lung air space; irregular rhythms and valvular murmurs may be present.

Vascular Assessment: Older Adults

Veins in older adults are thicker, less elastic, and more dilated, leading to dependent edema and varicosities.
Peripheral circulation decreases and peripheral pulses may be weak.

Assessment Techniques

Use inspection and palpation for peripheral vascular assessment.
Evaluate all extremities for symmetry, skin color, lesions, hair distribution, and quartous or distended veins.
Conduct circulatory assessment through the "P's": Pain, Pallor, Pulselessness, Paresthesias, Paralysis, and Polar temperature.

Assessing Capillary Refill

Evaluate peripheral blood flow by compressing the nail bed for 5 seconds. Normal color should return in less than 3 seconds.
Compare refill times across extremities; assess using the side of the toe if nails are too thick or discolored.

Peripheral Arterial Pulses

Locate and palpate pulses while ensuring symmetry.
Use Doppler if manual palpation is unsuccessful and assess strength and rhythm with fingertip pads.
Grading Scale for Pulses:
- 0: absent
- 1: diminished
- 2: normal
- 3: full
- 4: bounding

Current Health History

Note cardiovascular symptoms such as palpitations, syncope, fatigue, and leg pain or cramps.
Assess for chest pain characteristics and initiate appropriate care immediately for alarming symptoms.

Evaluate allergies, past medical history including heart conditions and risk factors, surgical history, previous tests, and medications.
Consider family and social history alongside nutritional assessments.

Physical Examination Techniques

Cardiovascular assessment involves inspection, palpation, and auscultation of the heart, focusing on locations like the 5th intercostal space and midclavicular line for the PMI.
Auscultation should be performed with the patient supine or sitting, and the area should be quiet, preventing distractions during examination. Stethoscope must be warmed prior to application.
