Study Notes
Vital Signs
- Vital signs encompass physiological data, including expected ranges and assessment techniques
- Nurses analyze alterations in vital signs and develop interventions
- Effectiveness of interventions is evaluated to assess client outcomes
- Accurate documentation of vital signs is essential
Blood Pressure
-
Blood pressure is the force exerted by blood against the circulatory system's walls
-
Measured in millimeters of mercury (mmHg), expressed as systolic/diastolic pressure
-
Systolic pressure represents maximum pressure during heart contraction
-
Diastolic pressure represents minimum pressure during heart relaxation
-
Cardiac output (CO): The amount of blood pumped by the heart per minute.
-
Stroke volume (SV): The amount of blood ejected per heart contraction.
-
Heart rate (HR): The number of heartbeats per minute.
-
Formula: CO = SV × HR (heart rate)
-
Effects: Increased CO = Increased BP, Decreased CO = Decreased BP, Lower SV/HR = Lower BP, Higher SV/HR = Higher BP
-
Factors influencing blood pressure: Blood volume (more = higher BP, less = lower BP), blood viscosity (increased viscosity = increased resistance = higher BP), vessel elasticity (decreased elasticity = increased vessel rigidity = increased BP), peripheral vascular resistance (increased resistance = increased BP), contractility (decreased contractility = lower CO = lower BP), Preload (low preload = lower SV & BP), Afterload (increased afterload = decreased contractility)
-
Cuff issues: Too narrow = overestimation, too wide = underestimation
-
Factors influencing blood pressure: Age, ethnicity, genetics, hormonal variations, weight, stimulants, medications, sodium intake, stress, activity, health conditions (pain, fever, hypoglycemia, heart failure)
Hypertension Classifications
- Elevated BP: Systolic 120-129 mmHg, Diastolic <80 mmHg
- Stage 1 Hypertension: Systolic 130-139 mmHg or Diastolic 80-89 mmHg
- Stage 2 Hypertension: Systolic ≥140 mmHg or Diastolic ≥90 mmHg
- Hypertensive Crisis: Systolic >180 mmHg and/or Diastolic >120 mmHg (requires immediate intervention)
Blood Pressure Measurement
- Equipment: Sphygmomanometer (cuff with inflatable bladder) and stethoscope (for Korotkoff sounds)
- When to use manual vs. electronic: Manual is preferred for children, older adults, critically ill patients, or when electronic readings are abnormal
- Correct cuff size: The cuff should encircle ~80% of the limb circumference
- Procedure (manual): Wrap the cuff, palpate artery, inflate 30 mmHg above expected systolic, slowly release air (~2 mmHg/sec), note first and last sound, record systolic and diastolic values
Orthostatic Hypotension
- Definition: A drop in blood pressure when moving to a sitting or standing position
- Causes: Dehydration, hypotension, heart failure, CNS disorders
- Assessment: Measure blood pressure while lying, sitting, and standing, noting any significant drops in systolic or diastolic pressure
Respiration
- Procedure: Position the patient, count respirations over a full minute, note the rhythm and depth of respiration
- Factors: Age, health status, medications, etc
Pulse
- Procedure: Palpate the radial pulse for a full minute, simultaneously measure apical and radial pulses if needed (apical using stethoscope)
- Factors: Age, health status, medications, activity, etc
- Pulse Deficit: Difference between apical and radial pulse rates (apical - radial)
Temperature
- Normal range: 36°C to 38°C (96.8°F to 100.4°F)
- Average: 37°C (98.6°F) for adults
- Factors: Activity, rest, diet, environment, age, health conditions
