CNA Course Week 5

• afebrile - without a fever
• apical-radial pulse - taking the apical and radial pulses at the same time
• blood pressure - the amount of force exerted against the walls of an artery by the blood
• body temperature - the amount of heat in the body that is a balance between the amount of heat produced and the amount lost by the body
• bradycardia - a slow heart rate that is less than 60 beats per minute
• diastole - the period of heart muscle relaxation
• diastolic pressure - the pressure in the arteries when the heart is at rest
• febrile - with a fever
• fever - elevated body temperature
• hypertension - high blood pressure
• hypotension - low blood pressure
• pulse - the beat of the heart felt at an artery as a wave of blood passes through the artery
• pulse deficit - the difference between the apical and radial pulse rates
• pulse rates - the number of heartbeats or pulses in 1 minute
• respiration - breathing air into and out of the lungs
• sphygmomanometer - a cuff or measuring device used to measure blood pressure
• stethoscope - an instrument used to listen to the sounds produced by the heart, lungs, and other body organs
• systole - the period of heart muscle contraction - the heart is pumping blood
• systolic pressure - the pressure in the arteries when the heart contracts
• tachycardia - a rapid heart rate over than 100 beats per minute
• thermometer - a device used to measure temperature
• vital signs - temperature, pulse, respirations, and blood pressure
• allergy - sensitivity to a substance that causes the body to react with signs and symptoms
• apnea - the lack or absence of breathing
• atelectasis - the collapse of a portion of the lung
• Biot's respirations - rapid and deep respirations followed by 10 to 30 seconds of apnea
• bradypnea - slow breathing, respirations are less than 12 per minute
• Cheyne-Stokes Respiration - respirations gradually increase in rate and depth and then become shallow and slow; breathing may stop for 10-20 seconds
• cyanosis - bluish color to the skin, lips, mucous membranes, and nail beds
• dyspnea - difficult or labelled breathing
• hemoptysis - bloody sputum
• hyperventilation - breathing is rapid and deeper than normal
• hypoventilation - breathing is slow, shallow, and sometimes irregular
• hypoxemia - a reduced amount of oxygen in the blood
• hypoxia - cells do not have enough oxygen
• Kussmaul respiration - very deep and rapid respirations
• orthopnea - breathing deeply and comfortably only when sitting
• orthopneic position - sitting up and leaning over a table to breathe
• oxygen concentration - the amount of hemoglobin containing oxygen
• pollutant - a harmful chemical or substance in the air or water
