25
What do you include in basic documentation of the pulse?
rate + location
26
What is a pulse deficit?
HR > pulse rate
27
What is the normal strength of a pulse?
Normal, strong (2+)
28
What is the normal rate of a pulse?
The normal rate is 60-100 beats per minute
29
What are the factors controlling blood pressure?
- cardiac output - vascular resistance - volume - viscosity - elasticity of arterial walls
30
When do I know to take blood pressure?
- the baseline bp is taken during a comprehensive exam or admission to the hospital - 5 mins rest, 3 measures 2 min apart, discard first and average second and third measure
31
What do you hear when listening to blood pressure in the arm?
- Korotkoff I tapping - Korotkoff II swooshing - Korotkoff III knocking - Korotkoff IV abrupt muffling - Korotkoff V silence
32
What is an auscultatory gap?
An abnormal silence in which you only hear the first and last taps
33
What is hypotension?
Low bp <95/60 | Symptomatic hypotension means low perfusion
34
What is hypertension?
High bp >140/90
35
What are you observing when measuring respirations?
Rate, rhythm, and effort
36
What is normal effort of respiration?
inspiration (active) < expiration (passive) | 1:2 ratio
37
How do you count respiration?
Count full inspiration + expiration for at least 30 seconds
38
What is the healthy ratio of pulse to respiratory rate?
4:1
39
What is tachypnea?
rapid respiratory > 20 breaths a minute
40
What is dyspnea?
difficult or uncomfortable breathing
41
What is bradypnea?
Less than 10 respirations a minute
42
What is the normal range of O2 sats?
>94%
43
What is the critical value for O2 sats?
<90%
44
What physiological skin changes result in for older adults?
- decreased protection - decreased temperature regulation - delayed healing
45
What are the leading increased risks from changes in skin for older adults?
- wounds - heat stroke (reduced ability to sweat) - hypothermia (reduced adipose tissue) - greater risk for infection
46
Definition of tissue integrity
4 types of tissue - muscle, neural, connective, and epithelial. This concept emphasizes structurally intact and physiological functioning epithelial tissues, such as the integument (skin and subcutaneous tissue) and mucous membrane.
47
What are the kinds of abnormal findings in the integumentary system?
- colour - lesions - edema
48
What are the kinds of objective data in the integumentary system?
``` A) Colour of patient's skin B) Palpate the temperature C) Moisture of skin D) Texture of skin E) Thickness of skin F) Palpate for edema G) Nail beds H) oral cavity I) palpate and inspect the scalp ```
49
What is edema?
(swelling) fluid that accumulates in the intercellular spaces
50
Pitting edema scale
1 to 4
51
Pitting edema 1+
Mild pitting, slight indentation, no perceptible swelling of the leg
52
Pitting edema 2+
Moderate pitting, indentation subsides rapidly
53
Pitting edema 3+
Deep pitting, indentation reminds for a short time, swelling of the leg
54
Pitting edema 4+
Very deep pitting, indentation lasts a long time, gross swelling and distortion of leg
55
How do you assess moles?
``` Asymmetry Border irregularity Colour variation Diameter > 6mm Evolution ```
56
What are the kinds of objective data in the peripheral vascular system?

60
What pulse site is used during CPR to assess circulation?
Femoral pulse
61
What pulse site is used to assess the peripheral circulation of the lower extremities?
Dorsalis Pedis pulse
62
What pulse site is commonly used to check HR when taking Vital Signs
Radial pulse
63
What pulse site is used to measure blood pressure?
Brachial pulse
64
Pallor definition
When red-pink tones from the oxygenated hemoglobin in the blood are lost, the skin takes on the colour of connective tissue (collagen), mostly white
65
Hypoxia definition
Oxygen deficiency
66
Febrile definition
Having or showing signs of a fever
67
Furrowed tongue definition
A tongue that looks like it has multiple cracks along the sides. Increases with age. Indication of dehydration
68
Preload definition
Is the venous return that builds during diastole. It is the length to which the ventricular muscle is stretched at the end of diastole just before contraction.
69
Cyanosis definition
Blueish, mottled discolouration that signifies decreased perfusion
70
Hypercapnia definition
High levels of carbon dioxide in the body
71
Pyrexia definition
Raised body temperature
72
Skin turgor definition
Mobility of skin from pinching a fold of skin. Good skin turgor immediately returns to original position
73
Afterload definition
The opposing pressure that the ventricle must generate to open the aortic valve against the higher aortic pressure
74
Diurnal cycle definition
24-hour cycle
75
Apnea definition
Temporary cessation of breathing; especially during sleep
76
Mean arterial pressure (MAP) definition
The pressure forcing blood into tissues averaged over the cardiac cycle
77
Erythema definition
Intense redness of the skin from excess blood (hyperemia) in the dilated superficial capillaries
78
Korotkoff sounds definition
The sounds are heard when the brachial artery is occluded by the blood pressure cuff in which there is no blood flow. The sounds are blood spurts into the artery.
79
