Define the following words….(without your books!!!!!)
• Work with a partner to check your knowledge before we proceed. How do you think the following groups of terms relate and what do they mean?
• Apical, Radial, Brachial, antecubital, stethoscope, intercostal space
• Tympanic, Axillary, Rectal, Oral
![Page 5: With Your Group, answer the following questions…](https://reader035.vdocuments.net/reader035/viewer/2022062323/5681554b550346895dc319f0/html5/thumbnails/5.jpg)
What are they?• Vital signs: the most important
measurements obtained for evaluating/assessing a client’s condition
• Temperature, Blood Pressure, Pulse, Respirations are indicators of patient status
• Any drastic change can lead to DEATH
• They are vital to life, hence the term VITAL SIGNS
![Page 6: With Your Group, answer the following questions…](https://reader035.vdocuments.net/reader035/viewer/2022062323/5681554b550346895dc319f0/html5/thumbnails/6.jpg)
Temperature (T)• Normal Adult Temp= 98.6
degrees Fahrenheit/ 37 degrees Celsius – Usual range 96.8 F to 100.4 F or 36
C to 38 C
• Variables that affect temp:– Time of day (lower in morning)– Allergic reaction– Illness– Stress– Exposure to heat/cold
![Page 7: With Your Group, answer the following questions…](https://reader035.vdocuments.net/reader035/viewer/2022062323/5681554b550346895dc319f0/html5/thumbnails/7.jpg)
Where can you find it????• Oral: in the mouth or
under the tongue• Axillary: armpit
(axilla)• Tympanic: ear canal• Rectal: through the
anus, in the rectum• Alternative methods:
surface of skin, through the blood
![Page 8: With Your Group, answer the following questions…](https://reader035.vdocuments.net/reader035/viewer/2022062323/5681554b550346895dc319f0/html5/thumbnails/8.jpg)
Types of Thermometers• 2 Types: electronic & glass• Electronic versions measure temp through a
probe at the end of the thermometer– Ex: Tympanic Thermometers– Probe covers are used to prevent contamination
• Glass versions contain mercury which rises until it matches the temperature– Round tip – for rectal temp (decreased risk of
injury)– Long tip- oral temp (more surface area)– Security tip – thin, short tip for oral and rectal
assessments• Handles are color coded for infection control

abbreviated?
![Page 10: With Your Group, answer the following questions…](https://reader035.vdocuments.net/reader035/viewer/2022062323/5681554b550346895dc319f0/html5/thumbnails/10.jpg)
PULSE (P)-A wave of blood flow created by heart contractions-You can palpate (feel) with 2 fingers or auscultate (listen for sounds) using a stethoscope or machine-Provides information about pulse rate and blood flow from left Ventricle to the assessment artery and its feeds-Pulse Sites: named according to nearby bones/structures
-Most common: Radial, brachial, apical
![Page 11: With Your Group, answer the following questions…](https://reader035.vdocuments.net/reader035/viewer/2022062323/5681554b550346895dc319f0/html5/thumbnails/11.jpg)
Most common…..-Radial: best palpated on the inside of the wrist (thumb side). Do not use your thumb!-Brachial: adults- antecubital space of the arm (bend of elbow); children- middle of the inside of upper arm-Apical: auscultated with stethoscope on chest wall
-Found at apex of heart, to the left of sternum, under the 5th/6th intercostal space-Used on infants and young children or adults prior to administering drugs, or for apical-radial deficit
![Page 12: With Your Group, answer the following questions…](https://reader035.vdocuments.net/reader035/viewer/2022062323/5681554b550346895dc319f0/html5/thumbnails/12.jpg)
Evaluating 4 Characteristics:
• 1. Pulse Rate: assess beats per minute, BPM/ bpm, counted for 15, 20, 30, 0r 60 seconds
• Normal ranges vary according to age & gender– Pulse rate decreases with age, WHY? – Women tend to have faster rates then men– Fitness levels significantly affect rates as do illness or disease
• Tachycardia is a faster than normal pulse rate – Caused by physical/mental stress, lack of oxygen (infection,
pain, exercise, emotional stress of crying infant)• Bradycardia is a slower than normal pulse rate
– Caused by physically fit athletes, heart meds, lack of Oxygen or BP
![Page 13: With Your Group, answer the following questions…](https://reader035.vdocuments.net/reader035/viewer/2022062323/5681554b550346895dc319f0/html5/thumbnails/13.jpg)

Evaluating 4 Characteristics:• 2. Pulse Rhythm: pattern of heartbeats which
should be regular and evenly paced• Arrhythmia and dysrhythmia- irregular heartbeat
– Must count pulse for full minute and average– Document as irregular– Caused by dysfunction, medications, lack of oxygen– May be normal for infants up until young adulthood
• 3. Pulse Volume: strength of the pulse, measurement of the pulse as it presses against the arterial wall and fingertips during palpatation
![Page 15: With Your Group, answer the following questions…](https://reader035.vdocuments.net/reader035/viewer/2022062323/5681554b550346895dc319f0/html5/thumbnails/15.jpg)
Evaluating 4 Characteristics:• Described as:
0 Absent, unable to detect1 Thready or weak, difficult to palpate and easily obliterated
by light pressure from fingertips2 Strong or normal, easily found and obliterated by strong
pressure from fingertips3 Bounding or full, difficult to obliterate with fingertips
- Thready may indicate decreased circulation due to obstruction, low BP, or weak heart contractions
- Bounding may indicate high BP or strong heart contractions

•What should you do prior to checking for
vital signs? (many things)
![Page 22: With Your Group, answer the following questions…](https://reader035.vdocuments.net/reader035/viewer/2022062323/5681554b550346895dc319f0/html5/thumbnails/22.jpg)
RESPIRATION (R)• The act of breathing or the exchange of oxygen and carbon dioxide- When counting, count 1 inhalation and 1 exhalation
as 1 respiration or complete breath- Respiratory Rate (RR)- most common assessment is
to watch patient’s chest movement for 1 minute- Can also use a stethoscope to auscultate RR- Tell adults you are listening to their heart
![Page 23: With Your Group, answer the following questions…](https://reader035.vdocuments.net/reader035/viewer/2022062323/5681554b550346895dc319f0/html5/thumbnails/23.jpg)
3 Characteristics of Respiration
• 1. Rate of Respiration: # of breaths / minute (count for entire minute)– Normal= 12-20 breaths / minute– RR typically decreases with size and age
• Increase in RR is called hyperventilation– Caused by physical/mental stress, increase body T,
lack of oxygen or low BP
• Decrease in RR is called hypoventilation– Caused by pain meds, alcohol, decrease in body T,
severe lack of oxygen, and no BP
![Page 24: With Your Group, answer the following questions…](https://reader035.vdocuments.net/reader035/viewer/2022062323/5681554b550346895dc319f0/html5/thumbnails/24.jpg)
3 Characteristics of Respiration• 2. Rhythm of Respiration: pattern
should be regular– Cheyne-Stokes: abnormal respiration
characterized by shallow breaths that increase to deeper breaths and then decrease to more shallow breaths. Then, apnea, or no breathing which lasts from 5-40 seconds
• 3. Quality of Respiration: seen in volume and effort– Volume: amount of air taken in and
expelled out of lungs (shallow or deep)
– Effort: amount of work patient uses to breathe (muscle use in neck, chest, abdomen is a sign of dyspnea)
![Page 25: With Your Group, answer the following questions…](https://reader035.vdocuments.net/reader035/viewer/2022062323/5681554b550346895dc319f0/html5/thumbnails/25.jpg)

Blood Pressure (BP)• BP: amount of pressure or tension exerted on
the arterial walls as blood pulsates through them
• 2 pressures are measured• Systolic BP (SBP): pressure exerted on the
arteries during the contraction phase of the heartbeat– Higher # because pressure should be higher in the
blood vessels when the heart is contracting• Diastolic BP (DBP): the resting pressure on the
arteries as the heart relaxes between contractions
• BP is written as a fraction and measured in mm of mercury (Hg) (ex. 120/80)
![Page 30: With Your Group, answer the following questions…](https://reader035.vdocuments.net/reader035/viewer/2022062323/5681554b550346895dc319f0/html5/thumbnails/30.jpg)
Expected BP Values• Systolic readings between 100-140mm Hg.• Diastolic readings between 60-90mm Hg. • Hypertension: high BP• Hypotension: low BP
– Body tries to raise BP– Signs of shock (lack of blood flow) may develop
• Change in level of consciousness• Increase in heart rate and respirations• Weak, thready pulse, • Pale, sweaty skin
![Page 31: With Your Group, answer the following questions…](https://reader035.vdocuments.net/reader035/viewer/2022062323/5681554b550346895dc319f0/html5/thumbnails/31.jpg)
Types of sphygmomanometers…• Mercury: calibrated glass cylinder
– Bottom of the miniscus, upper surface of liquid, forms point of reference as pressure rises
• Aneroid: calibrated dial with a needle that points to numbers on the face of the dial– Needle moves as pressure changes
• Electronic: digital display, usually includes the pulse rate and does not require a stethoscope

BP Sites
• Can be obtained at any artery at a pulse site• Brachial: upper arm (most common for adult and
older children)• Radial: lower arm (infants or clients with very
large upper arms)• Popliteal: thigh, alternative to arms due to
trauma, disease, medical tx to arms, mastectomy• Dorsalis pedis & posterior tibial; lower leg
(common on infants with automatic BP cuff)

BP Equipment & Steps• Sphygmomanometer: sphygmo (pulse),
mano (pressure), meter (measure)– Instrument used to detect blood pressure (BP
cuff)• 1. Place the cuff around extremity just above
pulse site• 2. Place stethoscope on artery at pulse site• 3. Squeeze and release bulb, pushing air into
the cuff to exert pressure on the artery• 4. Slowly release air from cuff• 5. Listen for sounds as mercury drops; note
the number when you first hear the sounds and when you last hear sounds (or they become softer)
![Page 35: With Your Group, answer the following questions…](https://reader035.vdocuments.net/reader035/viewer/2022062323/5681554b550346895dc319f0/html5/thumbnails/35.jpg)

Case Study
• 1.) Summarize the issue of concern• 2.) What is your legal obligation as a medical
professional?• 3.) What would you do?• 4.) Would it be difficult for you to do this? (for
example, would you wish you could do something differently but realize you cannot legally?)

Order of performance • Always perform least invasive first! Why?
– Noninvasive: observation, actions that do not intrude– Invasive: invading someone’s personal space
• Use this order if possible:– 1. Respiratory rate– 2. Pulse– 3. Temperature– 4. Blood Pressure
• P and T are often taken together• If taking rectal T, conduct last

Documenting and Reporting• Look for section in chart/computer
listed as VS (vital signs) or T P R BP. • If recording only numbers, be sure
to document in this sequence.– For example: 98.6-72-16-145/69
• Always report findings to supervisor if:– VS results fall outside of normal range
for Pt– VS result is significantly different from
a previous result recorded • Complete Chapter 9 Review pg 352-
