Oral Temperature Measurement Ask pt if they have ingested hot or cold food or drink, or smoked within the last ½ hour If yes, wait at least 15 minutes before measuring the oral temperature 3.01 Understand Diagnostic and Therapeutic Services
Aural Temperature Measurement Pros: Measures core body temperature Fast and convenient Con: Inaccurate if not placed correctly in the ear canal Ear infection Ear wax 3.01 Understand Diagnostic and Therapeutic Services
3.01 Understand Diagnostic and Therapeutic Services Pulse Pressure of blood on artery walls as the heart beats and relaxes Sites: Temporal – side of the forehead Carotid – side of the neck Brachial – inner elbow Radial – above the thumb at radius Femoral – upper thigh Popliteal – behind the knee Dorsalis pedis – top of the arch of the foot 3.01 Understand Diagnostic and Therapeutic Services
When would you use these pulse sites? Temporal Carotid Brachial Radial Femoral Popliteal Dorsalis pedis 3.01 Understand Diagnostic and Therapeutic Services
3.01 Understand Diagnostic and Therapeutic Services Pulse Normal rate adult (male) 60 – 70 beats per minute adult (female) 65 – 80 beats per minute children (over 7) 70 – 100 beats/minute children (1 – 7) 80 – 110 beats/minute infants (less than 1 year) 100 – 160 beats/minute Rhythm: regular or irregular Volume: strength of the pulse 3.01 Understand Diagnostic and Therapeutic Services
3.01 Understand Diagnostic and Therapeutic Services Pulse can be increased by: exercise stimulant drugs excitement fever shock nervousness 3.01 Understand Diagnostic and Therapeutic Services
3.01 Understand Diagnostic and Therapeutic Services Pulse can be decreased by: sleep depressant drugs heart disease coma 3.01 Understand Diagnostic and Therapeutic Services
3.01 Understand Diagnostic and Therapeutic Services Apical Pulse count taken with stethoscope Use if the patient has: Irregular heartbeat Arteriosclerosis Weak or rapid radial pulse Infants and children 3.01 Understand Diagnostic and Therapeutic Services
3.01 Understand Diagnostic and Therapeutic Services Respirations Process of taking in oxygen and expelling carbon dioxide 1 inspiration + 1 expiration = respiration Normal rate: adults – 12 – 20 breaths/minute children – 16 – 30 breaths/minute Evaluate for rhythm and character Rhythm – regular or irregular Character – depth, ease of breaths 3.01 Understand Diagnostic and Therapeutic Services
Abnormal respiratory patterns Apnea – periods of absent breathing Cheyne-stokes – periods of apnea and dyspnea Dyspnea – difficult breathing 3.01 Understand Diagnostic and Therapeutic Services
3.01 Understand Diagnostic and Therapeutic Services Blood pressure Pressure of blood on the arterial walls Recorded as a fraction: 120/80 Systolic pressure – wall of left ventricle is contracting Normal range: 100-140 mm Hg Diastolic pressure– wall of left ventricle is resting Normal range: 60-90 mm Hg 3.01 Understand Diagnostic and Therapeutic Services
3.01 Understand Diagnostic and Therapeutic Services Blood pressure Factors that elevate blood pressure: anxiety eating exercise excitement stimulant drugs Factors that lower blood pressure: depressant drugs excessive loss of blood rest shock 3.01 Understand Diagnostic and Therapeutic Services
Diagnostic Skills: Height and Weight Measured if warranted by patient’s age and physical condition Measured routinely: on admission to health care facility as part of annual physical examination each provider visit for children Important for evaluation of laboratory tests and calculation of medications 3.01 Understand Diagnostic and Therapeutic Services
3.01 Understand Diagnostic and Therapeutic Services Daily Weights used to monitor patients with chronic disease processes: Hormone disorders Renal disorders Heart disease Cancer 3.01 Understand Diagnostic and Therapeutic Services
3.01 Understand Diagnostic and Therapeutic Services Daily Weights Guidelines for daily weights: use the same scales at the same time wearing the same type of clothing patient voids to empty bladder Make sure to balance the scales before weighing the patient. 3.01 Understand Diagnostic and Therapeutic Services
OBSERVE SAFETY PRECAUTONS! Daily Weights OBSERVE SAFETY PRECAUTONS! Prevent injury from falls and the protruding height lever. 3.01 Understand Diagnostic and Therapeutic Services
Diagnostic Skills: Measure Visual Acuity Used to measure the ability to see Snellen charts: used to measure distant vision Ishihara method tests for color Tonometer measures intraocular pressure 3.01 Understand Diagnostic and Therapeutic Services
Diagnostic Skills: Measure Visual Acuity OD – right eye (oculus dexter) OS – left eye (oculus sinister) OU – both eyes (oculus uterque) Myopia – nearsightedness defect in distant vision Hyperopia – farsightedness defect in near vision 3.01 Understand Diagnostic and Therapeutic Services
