Study Notes
Vital Signs Overview
- Vital signs are indicators of basic body functioning.
- Include temperature, pulse, respirations, blood pressure, oxygen saturation (if applicable), and pain.
Importance of Vital Signs
- Provides baseline for comparison against future measurements.
- Offers objective data for healthcare assessment.
When to Assess Vital Signs
- During patient admission and discharge.
- As per physician's routine schedule.
- Before and after surgical/invasive procedures.
- Prior to and following medication administration.
- When there are changes in the patient’s condition or they report vague complaints.
- Regularly during specific nursing procedures.
Guidelines for Taking Vital Signs
- Be familiar with the patient's normal ranges and medical history.
- Use appropriate and calibrated equipment.
- Apply proper techniques and systematic approaches.
- Communicate any significant changes to appropriate healthcare staff.
- Control external factors affecting measurements.
Cultural Considerations
- Respect for various cultural beliefs regarding health treatments.
- Maintain patient privacy during assessments.
- Be sensitive to anxiety-inducing situations, and provide clear communication, using interpreters if necessary.
Temperature Measurement
- Types: Surface and core temperature.
- Normal ranges: Oral (98.6°F), Rectal (99.6°F), Axillary (97.6°F), Tympanic/Temporal (98.6°F); general range is 97°F - 99.6°F.
- Influencing factors: Age, exercise, hormonal changes, daily rhythms, stress, environment, smoking.
Temperature Measurement Sites
- Oral, rectal, axillary, tympanic, and temporal.
Devices for Measuring Temperature
- Electronic thermometers, tympanic thermometers, temporal artery thermometers, and strips.
Hyperthermia
- Known as febrile or pyrexia, indicating potential illness.
- Body's defense mechanism may cause damage if temperature is excessively high.
- Nursing interventions include administering antipyretics, ensuring hydration, and assessing for infections.
Hypothermia
- Abnormal body temperature below 93.2°F can be life-threatening.
- Indications may include rechecking abnormal temperatures.
- Treatment options include warming blankets and IV fluids.
Measuring Oral Temperature
- Ensure 20 minutes without food/drink before taking measurement.
- Use a thermometer appropriately and read after specified duration.
Measuring Rectal Temperature
- Use appropriate thermometer, lubricate, and hold in place as directed.
Measuring Axillary Temperature
- Considered least accurate; ensure axilla is clean and dry before taking a reading.
Measuring Tympanic Temperature
- Proper positioning for different ages; ensure snug fit of probe in canal.
Pulse Overview
- Indicates heart contractions, normal range is 60-100 beats per minute.
- Variations include bradycardia and tachycardia, affected by age, medications, and several physiological factors.
Pulse Sites
- Common sites include carotid, apical, brachial, radial, femoral, popliteal, and pedal.
Interventions for Abnormal Pulse
- Always check apical pulse for one full minute if abnormalities are present.
- Monitor blood pressure concurrently and observe for symptoms like chest pain or dizziness.
Respirations Overview
- Defined as breathing cycle; normal range is 12-20 breaths per minute.
- Influenced by illness, age, physical activity, and various other factors.
Interventions for Abnormal Respirations
- Check oxygen saturation; report readings below 94%.
- Monitor and auscultate breath sounds; observe signs of respiratory distress.
Blood Pressure Basics
- Reflects the force of blood against arterial walls, measured in mmHg.
- Consists of systolic and diastolic pressures, with normal ranges varying by individual factors.
Abnormal Blood Pressure Variations
- Hypotension: Blood pressure < 90/60; symptoms may include dizziness and tachycardia.
- Hypertension: Blood pressure ≥ 140/90; associated with various risk factors.
Interventions for Blood Pressure Abnormalities
- Recheck and monitor symptoms; provide education and medications as needed.
- Adjust lifestyle for managing blood pressure issues such as monitoring weight and diet.
Obtaining Blood Pressure
- Use appropriately sized cuff and position correctly over the brachial artery.
- Inflate and deflate cuff appropriately while listening for Korotkoff sounds; document findings carefully.
Height and Weight Measurements
- Record during admission, focusing on growth in children and ratio in adults.
- Weigh consistently under similar conditions and document changes.
Pulse Oximetry
- Measures oxygen saturation, with normal values typically between 95-100%.
- Consider limitations caused by external factors like nail polish or circulation issues.
