Significance of the Five Objective
Vital Signs
 Reveal how certain systems are functioning
 Provide data regarding patient’s overall
condition
 Provide a baseline against which subtle
changes can be measured
Copyright © 2011 F.A. Davis
Fundamentals of Nursing Care: Concepts, Connections, & Skills
Significance of Vital Signs
 Monitor patient’s physiological condition
 Identify new problems
 Determine if an intervention should be
performed
 Determine if prior interventions were effective

Priceless
 Vital signs are only of value when they are
accurate!
 Only a piece of the puzzle
 Must assess the whole person

Fundamentals of Nursing Care: Concepts, Connections, & Skills
When to Assess Vital Signs






Admission to hospital
Each visit to a clinic or emergency room
Each home health or hospice visit
Every 8 hours or according to hospital policy
According to physician’s orders
When a patient complains of feeling unusual
or different
 When you suspect a change in condition
Copyright © 2011 F.A. Davis
Fundamentals of Nursing Care: Concepts, Connections, & Skills
When to Assess Vital Signs (cont.)
 When administering medications
 Before, during, and after blood product
transfusion
 Before, during, and after surgical and
diagnostic procedures
 Every 4 hours when one or more vital signs
are abnormal
Copyright © 2011 F.A. Davis
Fundamentals of Nursing Care: Concepts, Connections, & Skills
When to Assess Vital Signs (cont.)
 A second time when an assessment finding is
different from the last assessment
 Every 5 to 15 minutes if patient condition
unstable
Copyright © 2011 F.A. Davis
Fundamentals of Nursing Care: Concepts, Connections, & Skills
Guidelines for Assessing Vital Signs
 Use an organized and systematic approach
 Use the appropriate equipment for each
patient
 Be familiar with normal ranges for different
ages
 Compare vital signs with previous vital sign
range for that specific patient
 Know the patient’s medical history, meds,
therapies
Copyright © 2011 F.A. Davis
Fundamentals of Nursing Care: Concepts, Connections, & Skills
Guidelines for Assessing Vital Signs
(cont.)
 Understand and interpret the vital sign
findings

changes to the physician and next shift nurse
 Minimize environmental effects on vital signs
Copyright © 2011 F.A. Davis

When to Reassess Vital Signs






After administering IV medications

shut; the first heart sound; the longer, lowerpitched sound; the lubb of “lubb dupp”
 S2: as the ventricles begin relaxation, the
pulmonary and aortic valves (semilunar
valves) close; a shorter, sharper sound; the
dupp of “lubb dupp”

BP Measurement
 Systolic
 Measurement of the force exerted by the blood
against the walls of the arteries during the
contraction of the heart ventricles
 Diastolic
 Measurement of the pressure exerted by the
blood on the artery walls while the heart is resting

BP Measurement
 Measured in millimeters of mercury (mm/Hg)
 Written as a fraction
 132/74
 Systolic—132
 Diastolic—74
Copyright © 2011 F.A. Davis
Fundamentals of Nursing Care: Concepts, Connections, & Skills
BP Measurement
 Pulse pressure
 Measurement of the difference between the
systolic and diastolic pressures
 Subtract the smaller number from the larger
 Usually 30 to 50
 Pulse pressure <30 or >50 is abnormal

BP Measurement
 Adult normal range
 90/60 to 120/80
 Systolic >120—pre-hypertension
 Refer to Table 17-1, pg. 347

BP Management
 Hypertension
 Systolic readings consistently >140 or diastolic
consistently >90
 Medical diagnosis of hypertension
 BP elevation must be documented on at least two
or more separate occasions

BP Equipment
 Cuff size makes a difference
 Cuffs available in child, small and large adult
 Correct size is necessary for an accurate
reading
 Too large ________________
 Too small ________________
 Width should cover approx. 2/3 upper arm
Copyright © 2011 F.A. Davis
Fundamentals of Nursing Care: Concepts, Connections, & Skills
Assessment Sites
 Normally upper arm with stethoscope over
the brachial artery at the antecubital site
 Lower arm with stethoscope over the radial
artery
 If necessary—midthigh with stethoscope over
the popliteal artery—Figure 17-4, pg. 348
 Systolic may be 10 to 40 mm/Hg higher

Korotkoff Sounds
 First sound: clear, rhythmic tapping sound,
gradually increasing in intensity
 Second sound: soft, swishing or murmuring
sound, representing turbulent blood flow
 Third sound: sharper, crisper rhythmic sound
 Fourth sound: softening or muffling of
rhythmic sound
 Fifth sound: silence

BP Measurement
 First sound—Systolic
 Point at which you last hear any sound—
documented as diastolic

Orthostatic Hypotension




Hypotension occurring with position change
When stand from a lying or sitting position
Dizziness, lightheadedness, or faint
Mild or prolonged
Copyright © 2011 F.A. Davis
Fundamentals of Nursing Care: Concepts, Connections, & Skills
Orthostatic Hypotension
 Normally
 Stand—blood pools in legs—body senses ↓--HR
↑--blood vessels constrict to ↑BP
 Possible causes—dehydration, heart disease,
diabetes, nervous system disorders, medications,
blood loss

Effects of Hypertension
on the Body
 Gradual loss of elasticity in arterial walls
results in less stretch and recoil
 Heart has to work harder to pump blood
through the cardiovascular system
