NURS 208 EXAM 1 WEEK 4 UPDATED ACTUAL
QUESTIONS AND CORRECT ANSWERS
Question:
What are the factors impacting oxygenation?
Answer:
respiratory function, cardiovascular function hemoglobin levels, age, body
health, temperature
Question:
Describe age related changes that impact oxygenation?
Answer:
- loss of elasticity in tissues, airways and alveoli - reduction of respiratory
muscles - more collapsible airways - decreased heart function
Question:
How does a nurse assess a client prescribed oxygen therapy?
Answer:
health history for cardiopulmonary function, medications, breathing pattern,
fatigue, lifestyle,
Question:
What is the concentration of oxygen in room air?
Answer:
Room air contains approximately 21% oxygen.
Question:
Know the concentration of oxygen received by the patient for all liter flow
rates? (How can you figure it out without memorizing?)
Answer:
"Each additional liter per minute via nasal cannula increases oxygen
concentration by about 4%; for example, 1 L/min H 24%, 2 L/min H 28%, etc."
Question:
What are the advantages of re-ceiving oxygen via nasal cannula?
Answer:
"allows the patient to talk, eat, and drink while receiving oxygen. 1-6 L/min
Question:
What are the disadvantages of re-ceiving oxygen via nasal cannula?
Answer:
dries mucosal lining, - req 4L/min of humidity tubes can breakdown skin
flammable can be dislodged easily.
Question:
Describe the nursing considerations when administering oxygen via simple
mask.
Answer:
maintain at least 5 L/min to prevent CO₂ retention, patients with
, claustrophobia may not tolerate it, \
Question:
What are the advantages of re-ceiving oxygen via simple mask?
Answer:
more comfortable than nasal cannula, provides humidified oxygen
Question:
What are the disadvantages of re-ceiving oxygen via simple mask?
Answer:
and may cause skin breakdown with prolonged use, inter-feres with eating
Question:
How long does it take to see a change in a patient condition when an oxygen
concentration is adjusted?
Answer:
"Typically within 20 minutes, though continuous monitoring is necessary."
Question:
What are the defined limits for oxygenation in a healthy individual?
Answer:
"Normal SpO₂ is 95-100%, and PaO₂ is 80-100 mmHg." - chronic lung disease
can let SpO2 go down to 88%
Question:
Describe the conditions that pulse oximetry can be helpful in identifying
potential problems leading to hypoxia?
Answer:
"It can detect desaturation in conditions like COPD, pneumonia, heart failure,
post-surgery recovery, and during sedation."
Question:
What are the sign and symptoms of hypoxia?
Answer:
"Restlessness, high pulse, rapid breaths, dyspnea, restlessness,
lightheadedness, cyanosis
Question:
Describe nursing interventions to increase oxygenation?
Answer:
position chest for maximum expansion, position changes, deep breathing,
ambulation, comfort measures
Question:
Describe the factors affecting nutrition?
Answer:
development, sex, health state, medication, economic factors, culture, I and O
Question:
Describe NPO.
Answer:
"NPO means "nothing by mouth" — the patient cannot eat or drink anything,
often before surgery or diagnostic testing."
