nursing fundamentals and clinical skills Flashcards
represents the balance between health produced and health lost by the body
body temperature
are relatively constant
core temps
fluctuate depending on blood flow to the skin and env conditions
surface temps
what are the temp measurement sites?
mouth, rectum, axilla, and tympanic
reflect fluctuations in the core temp. cannot be used in infants or sm children
oral temps
are the preferred method of measurement in young children who cannot use oral thermometers, should not be used for newborns due to the risk of anal perforations
rectal temps
is the safest site to measure temperatures in newborns
axillary temps
an easily accessible site that provides a core temperature quickly
tympanic membrane temp
site in easy to obtain without changing the clients position
temporal artery temp
bounding of arterial blood flow that is palpable at various points on the body
pulse
heart rate below 60bpm in an adult
bradycardia
heart rate above 100bpm in an adult
tachycardia
an irregular or abnormal rhythm
dysrhythmia
a normal increase in heart rate associated with inspiration
sinus arrhythmia
difference between apical and radial pusles
pulse deficit
the mechanism that the body uses to exchange gases between the atmosphere and the blood and between the blood and cells
respiration
regular but slow breathing at a rates of less than 12 breathes per min
bradypnea
regular but rapid breathing at a rate of greater than 20 breaths per min
tachypnea
laboured, deep respirations at a rate of greater than 20 breaths per min
hyperpnea
temporary cessation of breathing which then resumes
apnea
shortness of breath resulting in laboured or difficult breathing
dyspnea
an abnormal condition in which a person uses multiple pillows when lying down or must sit with their arms elevated and leaning forward to breathe deeply or comfortably
orthopnea
the indirect measure of arterial oxygen saturation and pulse rate
pulse oximetry
is the force of the blood under pressure pushing on the walls of an artery
BP
the peak of max pressure when the left ventricle contracts and ejects blood under high pressure into the aorta
systolic
is the min pressure exerted on the artrial walls when the ventricles relax
diastolic
the difference between systolic and diastolic pressures
pulse pressure
the temporary disappearance of korotoff sounds during auscultation of bp
auscultatory gap
persistently elevated BP and is often asymptomatic
hypertension
occurs when the systolic BP falls to 90 or below
hypotension
occurs when a person with bp within normal range develops symptoms and low bp when moving to an upright position
orthostatic hypotension
