GRADED A+
1. Definition of hypoxia: inadequate amount of oxygen available
2. signs of hypoxia: dyspnea, elevated BP with small pulse pressure, increased respiratory and pulse
rates, pallor, cyanosis, anxiety, restlessness, confusion, and drowsiness
3. symptoms of hypoxia: Headache, dizziness, skin turning blue, euphoria
4. cause of hypoxia: hypoventilation
5. Describe age related differences that influence care of the infants with respiratory problems:
Small chest, short airway, and aspirations are potential problems, more rapid RR, respiratory
activity is abdominal in infants, more rapid HR in infancy limits infant ability to increase CO by
increasing HR
6. Describe age related differences that influence care of the Toddler, Pre-K, School-Age
Children, Adolescents with respiratory problems: Pre-K child breathing tubes are less angular
and elongated
Colds and infections is lessened until child enters school.
Second hand smoke exposure ’ asthma
Child blood vessels widen and lengthen over time
BP increases over time
,7. Describe age related differences that influence care of the Older Adults with respiratory
problems: Tissues and airway of respiratory tract become less elastic (diaphragm moves less
efficiently), Power of respiratory and abdominal muscles is reduced, decreasing diaphragm
movement, Chest does not stretch as much, resulting in lower inspiration and expiration, All are
factors to increase disease risk
(pneumonia and chest infections)
8. Discuss complications of oxygen therapy.: Should use minimal oxygen to maintain adequate
SpO2 in the patient's target range to avoid complication, safety complications: oxygen supports
combustion, administration complications: too much/too little
9. Discuss the normal ranges of vital signs for adults.: Temperature: 96.4-99.5 , 35.8-37.5
Pulse (bpm): 60-100
Respirations: 12-20
BP: 120/80 (note the stages of hypertension)
10. Demonstrate the proper procedure for assessing oral temperature: wait 15 min if after hot or
cold fluids, smoking or chewing gum No oral diseases, or facial surgeries or use of face mask
11. Demonstrate the proper procedure for assessing tympanic temperature: do not use in patients
with ear drainage
12. Demonstrate the proper procedure for assessing temporal artery temperature: remove head
coverings, no sweat
,13. Demonstrate the proper procedure for assessing rectal temperature: core body temp and most
accurate, not done in children, those w// diarrhea, not w/heart disease or post heart surgery,
neutropenic or with low platelet count
14. Demonstrate the proper procedure for assessing axillary temperature: should be last method
used as it is least precise
15. describe factors that influence bradycardia: long-term physical fitness Hypothermia
Medications: digoxin, beta-blockers (propranolol), calcium channel blockers (verapamil)
Changing position from standing or sitting to lying down
Chronic severe pain
Hypothyroidism
Relaxation
16. describe factors that influence tachycardia: Exercise
Fever, heat exposure
Medications: epinephrine, levothyroxine, beta2-adrenergic agonists (albuterol) Changing position from
lying down to sitting or standing
Acute pain
Hyperthyroidism
Anemia, hypoxemia Stress,
anxiety, fear
Hypovolemia, shock, heart failure, hemorrhage
, 17. Describe how nasal cannula (low-flow) used to provide oxygen therapy.: most commonly used
in hospital/community settings for all ages, tube with 2 prongs that go into nostrils
18. Describe how nasal cannula (hi-flow) is used to provide oxygen therapy: continuous delivery
of O2 through heater/humidifier, small amount of continuous positive pressure (higher level of
oxygen delivery and improved breathing), used in
ICU patients for acute respiratory failure
19. Describe how Simple mask/non-reservoir mask is used to provide oxygen therapy: low-flow
device used when a higher oxygen level is needed than can be attained with nasal cannula; has
vents on side to allow room air to leak in; used when increased delivery of O2 is needed for less
than 12 hrs
20. Describe how the nonrebreather mask is used to provide oxygen therapy: delivers highest
concentration of oxygen via low flow mask, incorporates valves between bag and mask
21. Describe how the partial rebreather mask is used to provide oxygen therapy: similar to
simple face mask but has reservoir bag for collection of first part
of exhaled air, used to administer relatively high O2 concentrations, not commonly used in present day
practice
22. Describe how the venturi mask is used to provide oxygen therapy: high-flow, allows mask to
deliver most precise concentrations of oxygen, composed of large tube with oxygen inlet (venturi
barrel)
23. factors affecting body temperature: time of day (circadian rhythms), age, biological sex,
physical activity, state of health, environmental temperature
