    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
