Study Notes
Measurement and Units in Nursing
- The International System of Units (SI units) is the standard for measurement in healthcare to ensure consistency and accuracy in assessment and treatment.
- Common SI units and their conversions used in nursing include:
- Length:
- 1 meter = 100 centimeters
- 1 meter = 1000 millimeters
- Weight:
- 1 kilogram = 1000 grams
- 1 kilogram = 2.20462 pounds
- Volume:
- 1 liter = 1000 milliliters
- 1 liter = 33.814 fluid ounces
- Length:
- Temperature:
- 1 degree Celsius = (5/9) *(degree Fahrenheit - 32)
- 1 degree Fahrenheit = (9/5) * (degree Celsius) + 32
- Pressure:
- 1 kilopascal = 7.50062 millimeters of mercury
- Flow rate:
- 1 liter/minute = 1000 milliliters/minute
- Concentration:
- Various units like g/L and mg/mL are common
Nursing Instruments and Tools
- Stethoscope: Used to auscultate heart and lung sounds, and measure blood pressure.
- Blood pressure cuff (sphygmomanometer): Used to measure blood pressure.
- Thermometer: Used to take temperature. Types include oral, rectal, and forehead.
- Glucometer: Used to measure blood glucose levels.
- Pulse oximeter: Moniotrs blood oxygen levels and pulse rate.
- Scale: Used to measure weight.
- Tape measure: Used to measure length.
- Syringe: Used for administering medications or fluids.
- Needle: Used to inject medications or draw blood.
- IV infusion pump: Used to manage intravenous fluids.
- Percussion hammer: Used for assessment.
- Nebulizer: Used to administer medications.
- Pulse assessment tools
- Urinary Catheter
- Wound measuring tools
- Goniometer
- Peak flow meter
- Pulmonary function testing equipment
- Pain assessment tools
- EKG/ECG machine
- Ophthalmoscope and Otoscope
- Telemetry monitoring equipment
- Doppler ultrasound: Used for imaging body structures.
Patient Measurement Procedures
- Length: Measures height to assess growth, change in height over time, or for wound length.
- Weight: Measures body weight to evaluate nutritional status, monitor weight gain or loss, and determine appropriate medication dosages.
- Height: Measures patient height for calculating body mass index and for calculating dosages.
- Volume: Measures liquid volume to administer fluids properly.
Safety and Monitoring
- Nurses must be proficient in using instruments and follow proper protocols to ensure patient well-being.
- Accurate measurements are crucial for diagnosis, treatment planning, and monitoring patient progress.
Pressure Measurement
- Barometer: Measures atmospheric pressure, used in meteorology to monitor weather patterns.
- Sphygmomanometer: Used to measure blood pressure, a crucial part of patient assessment to diagnose and manage conditions like hypertension.
- Pressure in fluids is influenced by fluid density, gravity, and depth; nurses must account for these factors for effective patient care.
Fluid Pressure and Buoyancy
- Fluids exhibit pressure due to the weight of overlying fluid exerting force on the object submerged. This is a key concept in understanding pressure in fluids and buoyancy, also known as Archimedes' principle.
- Buoyancy is an upward force exerted on an object immersed in a fluid that counters the force of gravity. This force is equal in magnitude to the weight of the fluid displaced by the object. This is vital in understanding how objects float and is used in applications like aquatic therapy.
- Factors affecting pressure in fluids include the density, and gravity exerted on the object, and depth of the submerged object
Fluid Measurements in Nursing
- Nurses use these principles in measuring and monitoring fluid intake, output, and concentrations in various clinical situations.
- When assessing these, nurses consider the patient's condition, the nature of the fluids, and the clinical significance of these variables.
