A patient is undergoing oxygen therapy through a nasal cannula.If the patient inquires about the reason for having oxygen tubing in their nose, what explanation about the cannula should the nurse provide?

It allows you to remove it for a while when it gets uncomfortable.

It delivers the low concentration of oxygen you need.

It delivers a specific concentration of oxygen constantly.

It delivers the highest concentration of oxygen possible.

Answer and Explanation

The Correct Answer is B

Choice A rationale
While it’s true that a nasal cannula allows the patient to remove it for a while when it gets uncomfortable, this is not the primary reason for using a nasal cannula. The main purpose of a nasal cannula is to deliver oxygen.
Choice B rationale
A nasal cannula delivers the low concentration of oxygen that the patient needs. It is designed to provide a specific amount of oxygen, and the flow rate can be adjusted as needed.

Choice C rationale
While a nasal cannula does deliver a specific concentration of oxygen, it does not do so constantly. The amount of oxygen delivered can vary depending on the patient’s breathing rate and depth.
Choice D rationale
A nasal cannula does not deliver the highest concentration of oxygen possible. Other devices, such as non-rebreather masks, can deliver higher concentrations of oxygen.

Correct Answer is A

Explanation

Choice A rationale
Turning the patient on their side before starting oral care is a recommended practice when caring for an unresponsive patient. This position helps prevent aspiration, which can occur if the patient cannot swallow properly.
Choice B rationale
Applying petroleum jelly to the patient’s lips after oral care can help prevent dryness and cracking. However, it’s not the primary action the nurse should take when performing oral hygiene for an unresponsive patient.
Choice C rationale
Using the thumb and index finger to keep the patient’s mouth open is not recommended. It can cause discomfort and potential injury to the patient.
Choice D rationale
Using a stiff toothbrush to clean the patient’s teeth is not recommended. A soft toothbrush is usually used to clean the teeth of an unresponsive patient to prevent damage to the gums.

A. Instruct the client to use a pursed-lip breathing technique. B. Increase the oxygen flow to 3L/min. C. Have the client cough and expectorate secretions. D. Evaluate the client’s respiratory status.

Correct Answer is D

Explanation

Choice A rationale
Pursed-lip breathing can help improve oxygenation and reduce shortness of breath in clients with COPD. However, it is not the priority action when a client reports difficulty breathing.
Choice B rationale
Increasing the oxygen flow rate without a physician’s order can lead to oxygen toxicity or suppress the respiratory drive in clients with COPD. Therefore, this is not the priority action.
Choice C rationale
Coughing and expectorating secretions can help clear the airways, but it is not the priority action when a client reports difficulty breathing.

Choice D rationale
Evaluating the client’s respiratory status is the priority action. The nurse should assess the client’s breath sounds, respiratory rate, use of accessory muscles, and oxygen saturation to determine the severity of the client’s difficulty breathing and guide further interventions.
