(159 cards)
When do we asses vital signs? (5)
-On admission
-Any change in the health status
Immediately before and after surgery/invasive procedures
-Before giving certain medications
-Before and after nursing interventions that could affect vital signs
What are some factors that can affect vital signs?
-age
-gender
-race/hereditary
-medication
-exercise
Thermoregualtion deficiencies are common in what pts
Elderly and newborns
What may contribute to the development of hyperthermia ?
Exercise, activity and dehydration
When can you check for the highest and lowest temp
In the evening/night 8pm and 12mn
Early 4-6 am
Define body tempt and the various sites
It’s the balance between heat produced and heat loss from body

What’s the difference between febrile and a febrile
Fever vs non fever
What are the signs of fever?
Loss of appetite
Hot/dry skin
Thirst
Muscle aches
Fatigue
Respiration/pulse increase
Confusion in older adults
Imbalance in fluid/electrolytes
What are some interventions for pt with fever
Minitor temp /vitals
Check insensible water loss
Check level of consciousness
Monitor wbc, c &s lab values
Monitor inputs/outputs
Oral hygiene
Encourage fluid
Medicate with anitpyretics
Tepid sponge baths/cool packs
Monitor electrolytes
What are the 3 mechanism that involves hypothermia
Excessive heat loss
Inadequate heat production
Impairment of the hypothalamic thermoregulation
Heat loss from skin and respiratory tract
Signs of hypothermia ( body temp)
Decreased temperature
Severe shivering
Pale waxy skin
Increase bp ???
Disoriented
Drowsiness, lethargy coma
Poor muscle control
Decrease urinary output
What are some interventions for hypothermia
Monitor temp every 2 hrs
Administer blankets
Administer warming blankets as per md order
Admin warm fluids
Assess vitals frequently
Instruct pt to avoid extreme temperatures and dress adequately
What are the peripheral pulses
Temporal
Carotid
Brachial
Radial
Femoral
Popiteal
Posterior tibial
Pedal ( dorsalis pedis )
What are the pulse and respiration parameters
Adult
Aged adult
60-100 (80
40-100( 70
Factors of tachycardia
Pain
Strong emotions
Anxiety
Exercise
Prolonged heat exposure
Decrease bp or volume
Medication
Factors that effect bradycardia
Slow pulse at rest
In general male have slower pulse rate than female
Found in athletes
Medication such as beta blockers
Hypothermia
During sleep
Tell me about digoxin
Digoxin
Classified: cardiac glycosides
Increased contractility with increase co
Monitor electrolytes
Monitor therapeutic drug level
Know signs and symptoms of toxicity
What’s included in the upper and lower respiratory (
Mouth nose pharynx larynx
Trachea
Bronchi
Bronchioles
Alveoli
Pulmonory capillary
Pleural membranes
Oxygen transport
Transporter from the lungs to the tissues
97% of oxygen combines with hemoglobin in red blood cells and Carrie’s to tissues as oxyhemoglobin
Remaining oxygen is dissolved and transported in plasma and cells
( perfusion ? )
Carbon dioxide transport
Must be transported from the tissue to the lungs
Continually produced in the process of cell metabolism
65% is carried inside the red blood cells as bicarbonate
30% as catbheglobin
5% transported in solution in plasma and as carbonic acid
Diffusion ?
What’s the process of inspiration
Air flows into the lungs
Diaphragm and inter coastal contact
Thoracic cavity size increases
Volume of lungs increases
Intrapulmonary pressure decrease
Air rushes into the lungs to equalize pressure
