NUR215 Az College of Nursing Exam 4/ Q&A/
2024-2025.
1. What are the S&S of oxygen toxicity? - Answer: Pallor, sweating, nausea,
vomiting, seizures, muscle twitching, vertigo, tinnitus, hallucination, visual
changes, anxiety, respiratory changes, and decreased levels of consciousness.
Pulmonary S&S of oxygen toxicity include substernal chest pain, shortness of
breath, dry cough, and pulmonary edema or fibrosis.
2. What are the indications and nursing interventions for the following: nasal
cannula, - Answer: Delivers 24% to 44% at a flow rate of 1 to 6 L/min. Can lead to
skin breakdown and dry mucous membranes. Add a humidifier if O2 is greater
than 4L/min.
simple face masks,
, partial rebreather,
non-rebreather,
ambu-bag and
face tent? - Answer: Delivers 40% to 60% at flow rate of 5 to 8L/min. It provides
humidified oxygen. Patients may experience claustrophobia.
Delivers 60% to 75% at flow rate 6 to 11 L/min. Allows easier humidification of
oxygen. Patients with anxiety or claustrophobia do not tolerate it well.
Delivers 80% to 95% at flow rate 10 to 15 L/min. Delivers the highest O2
concentration.
24% to 50% at 4-10L/min
Delivers 24 to 100% at flow rate of at least 10 L/min. High humidification with O2
delivery. Requires frequent monitoring.
3. What are S&S of early/late hypoxia? - Answer: Early: Tachypnea, Tachycardia,
Restlessness, anxiety, confusion, Pale skin, high blood pressure use of accessory
muscles, nasal flaring, adventitious lung sounds.
Late: Stupor, Cyanotic, Bradypnea, Bradycardia, Hypotension, Cardiac
dysrhythmias.
Chronic: Clubbing of the finger and toes, peripheral edema, right sided heart
failure, respiratory acidosis, oxygen saturation less than 87%
4. How often should oral care be done on patients on oxygen therapy minimum? -
Answer: Give oral care BID minimum
