Objectives es By the end of this unit, the learners will be able to 1. Discuss the use of principles i of physics in nursing procedures. Introduction to the science of physics Relationship of physics to nursing Measurement and accuracy Sarfraz Masih, Principal, KKCON, Karachi 2
Introduction to Science of Physics Let s begin with a question What is science? Sarfraz Masih, Principal, KKCON, Karachi 3
Introduction to Science of Science Physics Science is a systemic way of acquiring knowledge of natural world which is based upon the belief that events in the world of nature occur not capriciously but according to an orderly. Sarfraz Masih, Principal, KKCON, Karachi 4
Introduction to Science of Physics Physics Physics is a branch of science which is related to study of how energy and matter influence each other. Physics has marked impact upon how modern, civilized man reasons, makes judgments and arrives at decisions. Sarfraz Masih, Principal, KKCON, Karachi 5
Relationship of Physics to Nursing Nursing leaders describe nursing as a kind of creative process in which the nurse makes important decisions and judgments. Nurses interventions affect the health and welfare of society members. So, it is very important that the nurse s decisions i and judgments should be intelligent and responsible. Sarfraz Masih, Principal, KKCON, Karachi 6
Relationship of Physics to Nursing The science of Physics offers the nurse who aspires to become an intervention agent inspiration, guidance, and challenge as well as countless models of the types of creative and critical thinking that have accelerated human progress.

Have A Look! General Relationship of Some Physiologic Processes, Therapeutic Procedures and Apparatus to Certain Aspects of Physics Sarfraz Masih, Principal, KKCON, Karachi 8
Heat E.g. Steam Inhalation Measurement Eg E.g. TPR Force E.g. BP Pressure E.g. O-2 Therapy Work & Energy E.g. Blood Aspects of Physics Motion E.g. Centrifuge Gravity E.g. Postural Drainage Molecular Physics E.g. Artificial Kidney Specific Gravity E.g. Urine Centre of Gravity E.g. Lifting pt. Sarfraz Masih, Principal, KKCON, Karachi 9
Accuracy & Measurement Accuracy Accuracy refers to the precision of the measuring instrument used to make a measurement. Sarfraz Masih, Principal, KKCON, Karachi 10
Accuracy & Measurement Measurement Measurement involves rules to assigning numeric values to qualities of the an object Characteristics ti of measurement Numeric value Unit E.g. 15 meters Sarfraz Masih, Principal, KKCON, Karachi 11
Accuracy & Measurement Units Units have been devised to Communicate the meaning of the measurement Achieve universal agreement about the measurement we have the systems of measurement. Sarfraz Masih, Principal, KKCON, Karachi 12
Systems of Measurement English / British Measurement System Metric System Sarfraz Masih, Principal, KKCON, Karachi 13
Systems of Measurement English System Unit of Length Foot (ft) Metric System Unit of Length Meter (m) Unit of Pound (lb) Unit of Kilogram Mass Mass (kg) Unit of Time Second Unit of Time Second Sarfraz Masih, Principal, KKCON, Karachi 14
English System Unit of Length Metric System 12 inches 1F Foot 10 millimeters 1 centimeter t 3F Feet 1Y Yard 10 centimeters 1d decimeter 1,760 Yards 1 Mile 10 decimeters 1 meter - - 10 meters 1 decameter - - 10 decameters 1 hectometer - - 10 1kil kilometer Sarfraz Masih, Principal, KKCON, hectometers Karachi Sarfraz Masih, Principal, KKCON, Karachi 15
Unit of Mass Definition of mass Definition of weight Sarfraz Masih, Principal, KKCON, Karachi 16
Mass Unit of Mass Refers to the quantity of matter that it contains. Weight Refers to the gravitational pull of the earth. Sarfraz Masih, Principal, KKCON, Karachi 17
English System Unit of Mass Metric System 24 grains 1 pennyweight 10 milligram 1 centigram 20 pennyweights 1 ounce 10 centigrams 1 decigram 12 ounces 1 pound 10 decigrams 1 gram - - 10 grams 1 decagram - - 10 decagrams 1 hectogram 10 hectograms 1 kilogram - - 1,000 1 metric ton kilograms Sarfraz Masih, Principal, KKCON, Karachi 18
Unit of Time The standard unit of time in both English and Metric Systems is mean (average) solar second Mean solar day is the average time, throughout 1 year, that it takes the earth to revolve once completely on its axis in respect to the sun (24 hours). Sarfraz Masih, Principal, KKCON, Karachi 19
Unit of Time 1 day 24 hours 1 hour 60 minutes 1 minute 60 seconds 1 day 86, 400 seconds Sarfraz Masih, Principal, KKCON, Karachi 20
