Oxygen therapy is primarily used to:

1. Increase blood pressure
2. Improve tissue oxygenation
3. Reduce body temperature
4. Increase heart rate

Normal oxygen saturation (SpO₂) in a healthy adult is:

1. 85–89%
2. 88–92%
3. 90–94%
4. 95–100%

Hypoxemia is best defined as:

1. Low carbon dioxide in blood
2. Low oxygen level in arterial blood
3. High oxygen level in tissues
4. Absence of breathing

Which oxygen delivery device provides the lowest oxygen concentration?

1. Simple face mask
2. Venturi mask
3. Nasal cannula
4. Non-rebreather mask

The usual flow rate for a nasal cannula is:

1. 1–6 L/min
2. 5–10 L/min
3. 10–15 L/min
4. 15–20 L/min

A non-rebreather mask can deliver oxygen up to:

1. 40%
2. 60%
3. 75%
4. 90–100%

Which patient condition most commonly requires oxygen therapy?

1. Hypertension
2. Hypoxemia
3. Hyperglycemia
4. Fever

The Venturi mask is best used when:

1. High oxygen concentration is needed quickly
2. Precise oxygen concentration is required
3. The patient is unconscious
4. Oxygen is needed during CPR

Which of the following is a sign of hypoxia?

1. Bradycardia
2. Cyanosis
3. Hypertension
4. Hyperthermia

For patients with COPD, oxygen should be administered carefully because it may cause:

1. Hypothermia
2. Oxygen toxicity
3. Respiratory depression
4. Increased blood pressure

Humidification of oxygen is important to:

1. Increase oxygen concentration
2. Prevent drying of mucous membranes
3. Reduce infection risk
4. Improve lung compliance

Pulse oximetry measures:

1. Partial pressure of oxygen
2. Oxygen saturation of hemoglobin
3. Carbon dioxide levels
4. Respiratory rate

Which oxygen device delivers a fixed FiO₂?

1. Nasal cannula
2. Simple face mask
3. Venturi mask
4. Partial rebreather mask

Prolonged use of high-concentration oxygen can lead to:

1. Atelectasis
2. Hypertension
3. Dehydration
4. Bradycardia

The nurse should first assess which parameter before starting oxygen therapy?

1. Blood pressure
2. Oxygen saturation
3. Body temperature
4. Blood glucose
