A client is receiving oxygen therapy via a nasal cannula. When the client asks the nurse why he needs to have oxygen tubing in his nose, which of the following explanations about the cannula should the nurse give him?

"It delivers a specific concentration of oxygen constantly."

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

"It delivers the low concentration of oxygen you need."

"It delivers the highest concentration of oxygen possible."

Answer and Explanation

The Correct Answer is C

A.   Nasal cannulas deliver a low flow rate of oxygen, which means the concentration of oxygen delivered is not constant and can vary depending on the client's breathing rate and depth.
B.   Nasal cannulas are designed to be worn continuously, and removing them can disrupt the delivery of oxygen and potentially worsen the client's condition.
C.   Nasal cannulas are typically used to deliver low concentrations of oxygen, which is often sufficient for patients with mild to moderate respiratory conditions.
D.   Nasal cannulas cannot deliver the highest concentration of oxygen possible. For patients who require higher concentrations of oxygen, other delivery methods, such as a face mask or mechanical ventilation, may be necessary.

Correct Answer is ["40"]

Explanation

Volume to administer (mL)=(Desired dose (mg)/ Concentration (mg/mL)

5 mg/ 5ml= 1mg/ml 40mg/1mg/ml= 40mls

Thus, the nurse should administer 40 mL of the prednisone oral solution.

A. Suppresses the urge to cough B. Reduces inflammation C. Dries mucous membranes D. Stimulates secretions

Correct Answer is D

Explanation

A. Expectorants do not suppress the urge to cough. Instead, they work by increasing the volume of respiratory secretions, making them thinner and easier to expectorate.
B. Expectorants do not have anti-inflammatory properties. They do not reduce inflammation in the airways.
C. Expectorants actually do the opposite. They increase the volume of respiratory secretions, making them thinner and easier to expectorate.
D. Expectorants work by stimulating the production of respiratory secretions, making them thinner and easier to cough up. This helps to clear the airways and relieve congestion.
