Bradycardia

A

less than 60 bpm

23
Q

Pulse Deficit

A

difference in apical & radial pulses
-requires 2 people
-1 takes apical other takes radial
apical is always higher than peripheral
shows blood flow to extremities

24
Q

Assessing Respirations

A

Inspection
-rate (bpm)
-depth (normal; deep; shallow)
-rhythm (regular; kushmal)
-work of breathing
-symmetry (2 lungs)

auscultation (listen to sounds)
-breath sounds

25
Q

Hypoventilation

A

shallow depth & low rate

26
Q

Hyperventilation

A

fast rate & depth

27
Q

Dyspnea

A

difficult breathing

28
Q

Tachypnea

A

fast breathing (increased rate)

29
Q

Orthopnea

A

difficult breathing laying down; easier breathing standing

30
Q

Apnea

A

without breathing

31
Q

Blood Pressure

A

-Force of blood against arterial walls
-highest pressure on arterial walls is systolic (ventricle is pumping)
-contraction of the ventricles

-lowest pressure on arterial walls is diastolic
-ventricles at rest

32
Q

AHA Blood Pressure Guidelines

A

Normal: less than 120/80
Elevated: systolic between 120-129 AND diastolic less than 80
**Stage 1: Systolic 130-139 OR diastolic 80-89 mm Hg
-lifestyle changes should begin at 130/80 mm Hg (monitor; lose weight; less salt)
-medication if patient is at risk for CV event
**Stage 2: Systolic at least 140 OR diastolic at least 90
**Hypertensive Crisis: Systolic over 180 AND/OR diastolic over 120

33
Q

Factors Affecting Blood Pressure

A

-age (older)
-race (AA hypertensive)
-circadian rhythm (lower in am)
-food intake (salt & fat in food)
-exercise
-weight (increased weight=increased BP)
-emotional state
-body position (lowest supine=flat)
-drugs/medications
-disease processes
-cigarette smoking (CO2 causes vasoconstriction-more force for narrow vessel)

34
Q

DID YOU KNOW THAT…

A

reducing salt or sodium intake to less than 2300 mg per day could reduce cases of high bp by 11 million and save $18 billion health care dollars every year

35
Q

Equipment for assessing blood pressure

A

-stethoscope & sphygmomanometer (BP cuff)
-doppler ultrasound
-electronic or automated devices

**2 step process is for auscultatory gap

36
Q

How to assess a manual BP

A

2 step method
-auscultatory gap

positioning (sitting up; arm level at heart)

37
Q

Assessing Blood Pressure

A

Listening for Korotkoff sounds with stethoscope
-first sound is systolic pressure
-the diastolic dilemma
-AHA: the point at which all sounds disappear
-5th Korotkoff sound

The brachial artery is most commonly used

38
Q

Clinical Decisions

A

-Where to obtain a BP reading
-Where not to obtain a BP reading (mastectomy; AV fistula; lymphoma; amputee; IV; dialysis ports)
-Size of the cuff
-What do I do in an isolation room? (clean cart when done)
-What do I do if the reading indicates hypertension of hypotension?

39
Q

AV Fistula’s

A

pulse on it=thrill (feels pulse)
hear sound=bruit (whooshing sound)

bruit over fistula is normal; connects artery to vein

40
Q

Hypertension

A

over 120/80

41
Q

Hypotension

A

90/60 WITH symptoms

42
Q

Orthostatic Hypotension

A

Start supine; sit up
drop 20 mm Hg in systolic or 10 mmHg in diastolic when changing position means you have orthostatic hypotension

43
Q

Primary hypertension

A
44
Q

Secondary hypertension

A

due to other disease

45
Q

Always record BP in even numbers

A
46
Q

Automatic BP machines

A

advantages:
-ease of use
-efficient when repeated measurements are indicated
-do not need a stethoscope

limitations:
-expensive equipment
-requires electricity & space
-sensitive to outside motion
-vulnerable to error in..
-arrhythmias
-obese extremity
-hypotension

47
Q

MAP

A

need a mean arterial pressure of 60mm Hg or greater to perfuse vital organs

normal: 70-100
minimum: 60

MAP=2 x diastolic + systolic/3

48
Q

Pain is subjective & is always what the patient says it is!

A

Intensity-Scales
-Mild (1-3) Moderate (4-6) Severe (7-10)
-FLACC scale: face, legs, arms, cry, consolability
-PAINAD: for dementia (grimacing; withdrawal @ touch)
**see pain handout sheet
-onset
-location (where)
-functional limitations (stopping you from doing something)
-pain interventions (meds; massage; reposition)
-patient’s functional goal (chronic pain 10/10 to get to 3/10)

reassess in 4 hours or sooner

49
Q

Why do we under treat pain?

A

personal biases
hcp incorrectly believe: pain is normal part of aging (it is NOT); pain relief may lead to respiratory depression or addiction
insufficient education for nurses on how to pain assessment
older adults fear they will become addicted
cognitive or communication impairments in older adults

50
Q

Pulse Oximetry SpO2

A

**measures the amount of hemoglobin saturated with oxygen in arterial blood (not venous because oxygenated)
-measures oxygenation NOT ventilation (for both do ABG)
-Normal healthy adult >95%
-Most adults with disease we accept >92%
-<92% may indicate that O2 to the tissues is inadequate
-in patients >80 yo and with lung disease (accept lower number)
-85%-89% SpO2 levels may be their acceptable norm
-less than 85% is abnormal in everyone!!
hypoxemia kills

**amount of O2 breathed need fiO2
88% on room air is way different than 88% on O2

51
Q

What to do if O2 reads 89%?

A

reposition (sit up/raise head) & take a deep breath

52
Q

Factors affecting pulse oximetry readings

A

interference with light transmission:
-outside light sources
-carbon monoxide (could also reflect light like O2)
-patient motion
-jaundice
^^estimate low
-skin pigmentation may result in signal loss or over estimation of saturation (false high)

interference with arterial pulsations:
-peripheral vascular disease
-hypothermia at assessment site
-low cardiac output..not good perfusion
-hypotension..not good perfusion
-peripheral edema..not good perfusion
-tight probe
-arrhythmias
-edema

53
Q

Criteria for Rapid Response Team (why we measure vitals)

A

-heart rate over 140/ min or less than 40/min
-respiratory rate over 28/min or less than 8/min
-systolic blood pressure greater than 180 mm Hg or less than 90 mm Hg
-oxygen saturation less than 90% despite supplementation
-acute change in mental status

54
Q

Differences in books normal vital signs

A

Taylor for fundamentals:
T: 35.8-37.5
P: 60-100
R: 12-20
SpO2: 95%-100% be aware of Hgb..what is acceptable may change in patients with COPD, COVID, and other circumstances

Jarvis for health assessment:
T: 35.8-37.3
P: 60-100
R: 10-20
SpO2: 97%-99% on RA or 95% clinically acceptable with normal Hgb
