  1. Weights and Measures Nurses Assistant Unit 7

  2. Common Equivalencies • Metric Weight: • 1kg=2.2lbs • Metric Height: • 1cm=.39inches • 1inch=2.5cm • Medical Weights and Measures: • 1cc= 1ml • 1ounce= 30cc • 1teaspoon= 5ml • 1cup=8 ounces= 240ml • 1pint=16 ounces= 500ml • 1quart=32ounces= 1000cc • 1liter= 1000ml

  3. Weights and Measures used in the average U.S household • Weight is measured in ounces (oz) and pounds (lbs) • Length is measured in inches, feet, and yards • Liquid volume is measured in fluid ounces, pints, quarts, and gallons

  4. Liquid Measuring Equipment • Graduate Cylinders • Cylinders are marked with lines and numbers • Measurements for cylinders are marked in ounces and (cc’s) • Other equipment used, urinals,med cups,hats,specimen cups.

  5. Procedure for Measuring Liquid Volume • Pour liquid into graduate container • Place on flat surface • Read at eye level • Use measurements at lowest level of liquid surface • Record measurements using correct abbreviations for unit measurement

  6. Procedure for Measuring Length/ Height • We can use a measuring tape to measure the heights of residents who are contracted, stooped, or in bed • Measure in segments, while marking the sheet with a pencil • Add all measurements together to find a total

  7. Procedure for Measuring Length/ Height Cont… • Measuring a residents Ht using an upright scale • Assist the resident to remove their slippers • Place a paper towel on the scale for infection control purposes • Assist the resident to stand on the scale facing away • Lower the height measuring rod until it rests on the residents head • Record their Ht, reading is made at the moveable point using centimeters.You DO NOT need to convert! • Assist the resident off of the platform

  8. Procedure for Measuring Weight • Make sure the scale is balanced at zero • Place paper towel on the scale • Remove residents slippers and help resident to step onto the scale facing forward • Read the scale when in balance to the nearest quarter pound (or tenth of a kilogram) and record • Help the resident off of the scale • Return and clean equipment

  9. Procedure for Measuring Weight Cont… • Make sure to weigh residents at the same time everyday for accuracy • Types of scales Wheelchair scale Mechanical lift (hoyer) scale Bed scale

  10. Military Time • Military time is a concise method of expressing time used by the military, emergency services, hospitals, and other entities • Only uses four digits and no colons • Does not use AM or PM • When converting from military time to regular time and vice versa, the minutes and seconds do not change

  11. Military Time Cont… • Examples: • 3:00AM = 0300 • 3:30PM = 1530 • 12:00AM = 2400 or 0000 • 12:00PM = 1200 • What time do you go to sleep? • Hint: The only way you are going to learn this is sheer memorization or adding/subtracting from 1200 • For example 3pm + 12=15 now just add the minutes…1500 11:15pm+12=23 2315 • 6am=simply insert zeros 0600 • 10am=just simply remove colon=1000
