Question 1 of 5.
A 62-year-old man is admitted with emphysema and acute upper respiratory infection. Oxygen is ordered at 2 L/min. The reason for low-flow oxygen is to:
A. prevent excessive drying of secretions.
B. facilitate oxygen diffusion of the blood.
C. prevent depression of the respiratory drive.
D. compensate for increased airway resistance.
Explanation: In COPD, low oxygen levels drive respiration. Low-flow oxygen prevents suppression of the respiratory drive, which could occur with high-flow oxygen.
Question 2 of 5.
The school nurse is presenting a class to students at a primary school on how to prevent the transmission of the common cold virus. Which information should the nurse discuss?

C. Tell the children they should go to the doctor if they get a cold.
D. Demonstrate to the students how to wash hands correctly.
Explanation: Handwashing (D) is the most effective way to prevent cold transmission. Tissues (A) are secondary, immunizations (B) don’t prevent colds, and doctor visits (C) are unnecessary for most colds.
