(Select All that Apply.)

Increase oxygen flow rate if the patient appears anxious.

Administer high-flow oxygen to quickly relieve hypoxemia.

Monitor the patient's respiratory rate and effort frequently.

Adjust oxygen flow rate to maintain a saturation level of 88-92%.

Use a non-rebreather mask to maximize oxygen delivery.

Encourage the patient to take deep breaths frequently.

Answer and Explanation

Correct Answer : C,D

A.   Increasing the oxygen flow rate due to anxiety can worsen carbon dioxide retention, which is dangerous in COPD patients.
B.   High-flow oxygen is typically not recommended for COPD patients because it can suppress respiratory drive.
C.   Monitoring the respiratory rate and effort is crucial to ensure the patient is not retaining carbon dioxide or experiencing further respiratory distress.
D.   Adjusting the oxygen flow rate to maintain a saturation level of 88-92% is recommended for COPD patients to prevent hypercapnia.
E.   A non-rebreather mask is generally not used for COPD patients, as it can deliver too much oxygen, leading to carbon dioxide retention.
F.   Encouraging deep breathing can help, but it is more important to focus on maintaining the proper oxygen saturation.

Correct Answer is C

Explanation

A. Airway obstruction in asthma is not caused by thinning mucus. It is primarily due to bronchospasm, inflammation, and thickening of the mucus.
B. Decreased mucus production does not contribute to airway constriction in asthma. In fact, excessive mucus production is a key feature of asthma, leading to obstruction of the airways.
C. Bronchospasm in asthma involves inflammation, edema, and excess mucus production. These factors cause narrowing of the airways, leading to difficulty breathing.
D. Inflammation leads to airway narrowing, but it does not reduce the airway diameter in the sense of preventing bronchospasm. Bronchospasm occurs as a result of inflammation and muscle contraction.

A. A Venturi mask allows for precise oxygen concentration delivery. B. Oxygen should be humidified when delivered at flow rates higher than 4 liters per minute. C. Oxygen toxicity can occur when high concentrations of oxygen are administered for extended periods. D. Nasal cannulas can deliver oxygen concentrations up to 90%. E. Oxygen therapy is always safe regardless of the patient's condition. F. A simple face mask can deliver higher oxygen concentrations than a non-rebreather mask.

Correct Answer is ["A","B","C"]

Explanation

A. A Venturi mask is an accurate way to deliver a specific concentration of oxygen, allowing for precise control.
B. Humidifying oxygen is recommended at flow rates higher than 4 liters per minute to prevent drying of the mucous membranes.
C. Oxygen toxicity can occur if high concentrations of oxygen are administered for prolonged periods, leading to potential lung damage.
D. Nasal cannulas typically provide a lower oxygen concentration than higher-flow devices, like a Venturi mask or non-rebreather mask.
E. Oxygen therapy is not always entirely safe regardless of the patient's condition; certain conditions require careful monitoring to prevent complications.
