41
WBC > 11,000
leukocytosis- dealing with some sort of infection, can be a result of increase stressed, symptoms can include fever, weakness, dizziness
42
Low Plt
increased risk of bruising, bleeding, need to be mindful of fall risks/bumping into things
43
High plt
increased risk from thrombosis (clot)

58
Bronchial Lung Sounds
heard adjacent to manubrium/main stem bronchi, longer expiratory vs inspiration sound, low pitched, hollow sound
59
Respiratory Rate
Normal: 12-18 breaths per minute, tidal volume 500cc
60
Physiological Effects of BedRest
-deconditioning: loss of physiologic and performance adaptations -multi-system involvement
61
Atrophy: bed rest
predominate response to rest , reduction in muscle bulk and density in bone size, can also see a loss of neuromuscular excitation
62
muscle length: bed rest
Reduced ROM, loss of muscle fiber length, contracture formation/deformities (affects blood flow, puts pt at risk for pressure injuries)
63
cardiovascular adaptations : bed rest
reduction of aerobic power, reduced CO from reduced blood volume, increased HR, increased venous compliance (stretch), orthostatic intolerance (trouble getting blood to head)
64
orthostatic intolerance : bed rest
*postural hypotension* -plasma volume loss and excessive pooling of blood in lower extremities when upright -decline in cerebral perfusion
65
vital sign changes: bed rest
-increased HR (trying to maintain CO) -exaggerated HR response w/ activity *3 days of BR ^32% *7 days of BR ^62% *21 days of BR ^89%
66
DVT : bed rest
people on airplanes are at risk -Virchows Triad (venous stasis, hyper coagulability, vessel trauma) -reduced muscle pump -manifestations are pain and swelling
67
risk of PE: bed rest
PE- peripheral clot that travels and lodges in lung symptoms of PE: dyspnea, tachypnea, chest pain, cough
68
pulmonary affects: bed rest
-reduced ventilators muscle strength and endurance -decreased strength of contraction -increased RR and work of breathing -contributes to atelectasis (collapse of alveoli) mucus pooling and impaired cilia functioning * PNEUMONIA*
69
gastrointestinal affects :bed rest
-reduced appetite, fluid intake -increased risk for reflux -constipation
70
genitourinary affects: bed rest
-increased diuresis (excretion of sodium's and fluid in urine, reduced blood volume) -difficulty voiding -increased risk of UTI
71
integumentary affects: bed rest
-pressure injuries (bony prominences)
72
psychological affects: bed rest
-increased number of stressors *isolation* -sleep deprivation -impaired cognition -dependency -reduced tolerance to pain -depression and anxiety -delirium
73
Delirium: bed rest
sense of vulnerability, high confusion **movement can clear delirium**
74
VS respiratory rate (normal)
12-18 breaths per minute equal rate and depth
75
VS Pulse Rate norm
60-100 beats per minute
76
VS blood pressure norm
120/80
77
