Quiz: Oxygen safety

What is oxygen therapy?

Oxygen therapy provides supplemental oxygen to patients with respiratory distress or low oxygen levels.

True or false: Oxygen is flammable.

False, because oxygen supports combustion but does not burn itself.

Difference between low-flow and high-flow oxygen systems.

- Low-flow: delivers variable oxygen concentration. - High-flow: delivers a fixed oxygen concentration.

Fill in the blank: The safe storage temperature for oxygen cylinders is _____ degrees Fahrenheit.

The safe storage temperature for oxygen cylinders is below 125 degrees Fahrenheit.

What is the purpose of a pulse oximeter?

A pulse oximeter measures oxygen saturation levels in the blood non-invasively.

True or false: Oxygen can be given freely without monitoring.

False, because oxygen administration requires monitoring to prevent toxicity.

What should you do in case of an oxygen fire?

Immediately shut off the oxygen supply and use a fire extinguisher.

Risk of oxygen toxicity includes _____ damage.

Risk of oxygen toxicity includes lung damage due to high concentrations.

Indications for oxygen therapy include _____ and _____ .

- Hypoxemia - Chronic obstructive pulmonary disease (COPD)

What is a nasal cannula?

A nasal cannula is a device that delivers oxygen directly into the nostrils.

True or false: Humidification is not needed for oxygen therapy.

False, because humidification is necessary for high-flow oxygen to prevent dryness.

Fill in the blank: An oxygen saturation level of below _____% indicates hypoxemia.

An oxygen saturation level of below 90% indicates hypoxemia.

What is the role of the nurse in oxygen therapy?

The nurse assesses, administers, and monitors oxygen therapy to ensure patient safety.

Difference between COPD and asthma in oxygen use.

- COPD: requires long-term oxygen therapy. - Asthma: may need intermittent oxygen therapy.

What is an oxygen mask?

An oxygen mask is a device covering the nose and mouth to deliver higher oxygen concentrations.

True or false: Oxygen can cause hypercapnia.

True, because excessive oxygen can suppress respiratory drive in some patients.

Fill in the blank: The maximum flow rate for a nasal cannula is _____ L/min.

The maximum flow rate for a nasal cannula is typically 6 L/min.

What is a venturi mask?

A venturi mask delivers a precise concentration of oxygen using airflow principles.

True or false: Patients should sleep with oxygen on at all times.

False, because oxygen use during sleep should be evaluated for safety.

What is the significance of checking oxygen cylinder labels?

Labels indicate the contents and pressure, which are critical for safe use.
