Question d, Physical Examination rationale for methodology BP Blood pressure reflects the pressure that is exerted on the walls of the arteries. Varying with cardiac cycle, high with systole and low with diastole. A measurement of the pressure of the blood in the arteries. As ventricles contract you have systolic blood pressure and when the ventricles relax you have diastolic blood pressure. Expressed as a ratio of the systolic over diastolic pressure external influences like caffeine, nicotine, exercise, emotions, pain and temperature affect blood pressure as it reflects the stroke volume of the volume of blood ejected with each heartbeat. Blood pressure can vary depending on the position of the body and of the arm. (Preassessment Overview, 2003) HR When the heart contracts a shockwave is produced pumps blood forcefully out of the ventricles into the aorta the shock wave travels along the fibres of the arteries and is commonly called the arterial or peripheral pulse. The pulse weather regular, irregular, thready or strong, gives a good overall picture of the clients health status. Several characteristics should be assessed when measuring the radial pulse rate, rhythm, amplitude, contour and elasticity of the various characteristics. amplitude can be quantified as follows 1 thready or weak 2 normal 3bounding If abnormalities are noted during assessment of the radial pulse further assessment should be performed for more information on assessing pulses and abnormal pulse findings (Preassessment Overview, 2003) Rr The respiratory rate is an additional clue to the clients overall health status. Respirations can be easily observed without alerting the client by watching chest movement before you have removing the s... ... middle of paper ... ...ploadedFiles/ClosingTheGap/Content/Publications/2013/ctgc-ip07.pdf (2003).
