Flashcards in Vital Signs powerpoint Deck (78)
What is V/S?
Measures of a pt's physiological statistics in order to asses body functions as they reflect changes that are not readily observed
The balance between heat produced and lost is called?
The wave of blood traveling through the arteries as a result of each heartbeat is called?
The act of breathing is called?
The force exerted by the blood against a vessel wall is called
What is the fifth and sixth V/S?
Pain is the fifth and Pulse Oximetry is the sixth
When are V/S to be taken?
1: upon admission
2: schedule time according to policies
3: any changes in health status
4: pre & post op
5: pre/post administration of meds
6: pre/post nsg intervention that may affect V/S
What are the normal ranges of temp?
What are the three factors in thermoregulation?
1: The hypothalamus controls thermoregulation by setting the temp point
2: Skin regulation via heat transmitted from the blood through the walls of the vessels to the surface; skin receptors (mostly cold and mostly on the face) that send signals to the hypothalamus
3: Behavior control affected by thoughts, emotions, and mobility
What part of the hypothalamus controls heat loss by vasodilation and diaphoresis?
The anterior hypothalamus controls heat loss by vasodilation and diaphoresis
What part of the hypothalamus controls heat production/conserves via vasoconstriction, voluntary muscle contraction, shivering?
The posterior hypothalamus controls heat production/conservation via vasoconstriction, shivering
What areas of the body would I measure for core temp?
Rectum (the most accurate), tympanic, and vascular access
What area of the body would I measure for surface temp?
Skin, axilla, and oral (most convenient)
What are the phases of a fever?
The levels of fever include onset/chill phase, course/plateau phase, and the abatement/flush phase
What phase of fever constitutes heat conservation rising the set point?
Onset/chill phase is where heat conservation causes the rise in set point
What phase of fever constitutes chills subsiding as the skin becomes warm and dry and where the set setpoint is set?
Course/plateau phase is where the chill subsides as the skin is warm and dry as the set point has been set
What phase of fever constitutes the fever to break and when diaphoresis occurs?
Abatement/flush phase is when the fever breaks and diaphoresis occurs
What are the patterns/types of fever?
The patterns of fever: constant/sustain, intermittent, remittent, and relapsing
What kind of fever occurs as the temp alternates @ regular intervals between periods of normal and subnormal levels?
intermittent = malaria
What kind of fever occurs as a wide range of fluctuations occurring over a 24 hr period showing an above normal temp?
remittent = cold/flu
What kind of fever occurs when there are short periods of febrility in a span of a few days punctuated w/periods of 1-2 days afebrility?
relapsing = ticks or lice
What kind of fever occurs when a body temp fluctuates minimally but always remain above normal?
constant = typhoid
What type of elevated temp is seen with skin that's hot and dry, no diaphoresis, and a temp >106 F?
What type of elevated temp is seen with profuse diaphoresis and a temp >101 F?
A core body temp that's below the normal limit is called?
A wave of blood created by contraction of the ____ ventricle of the heart is called?
Pulse = L
What do pulse waves represent?
Pulse waves represent the stroke volume output or the amount of blood that enters the arteries.
What are the pulse points?
temporal, carotid, brachial, radial, apical, femoral, popliteal, posterior tibial, dorsalis pedis
How does age affect pulse?
as age increases, pulse decreases
