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.
Health History Related to Cardiovascular System
- 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.
