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 C

Explanation

Choice A rationale
Increasing the client’s oral fluid intake is not the immediate action the nurse should take. While hydration is important, it does not directly address the client’s low oxygen saturation.
Choice B rationale
Initiating humidification therapy can help to thin secretions and improve oxygenation, but it is not the immediate action the nurse should take.
Choice C rationale
Raising the head of the bed is the first action the nurse should take. This position can help to improve lung expansion and oxygenation.
Choice D rationale
Encouraging the client to cough and deep breath can help to clear secretions and improve oxygenation, but it is not the immediate action the nurse should take.

A. 1 tablet B. 2 tablets C. 3 tablets D. 4 tablets

Correct Answer is B

Explanation

Step 1 is: The prescribed dose is 100 mcg and each tablet contains 50 mcg.
Step 2 is: Divide the prescribed dose by the amount per tablet. So, 100 mcg ÷ 50 mcg/tablet. Step 3 is: The result is 2 tablets.
