1. 1.
A patient is having her tonsils removed.The patient asks the nurse what function the tonsils
normally serve.Which of the following would be the most accurate response?
A)
The tonsils separate your windpipe from your throat when you swallow.
B)
The tonsils help to guard the body from invasion of organisms.
C)
The tonsils make enzymes that you swallow and which aid with digestion.
D)
The tonsils help with regulating the airflow down into your lungs.
Ans B
Feedback
The tonsils, the adenoids, and other lymphoid tissue encircle the throat. These structures are
important links in the chain of lymph nodes guarding the body from invasion of organisms
entering the nose and throat. The tonsils do not aid digestion, separate the trachea from the
esophagus, or regulate airflow to the bronchi.
2. 2.
The nurse is caring for a patient who hasjust returned to the unit after a colon resection. The
patient is showing signs of hypoxia. The nurse knows that this is probably caused by what?
A)
Nitrogen narcosis
B)
Infection
C)
Impaired diffusion
D)
Shunting
Ans
D
Feedback
Shunting appears to be the main cause of hypoxia after thoracic or abdominal surgery and most
types of respiratory failure. Impairment of normal diffusion is a less common cause. Infection
would not likely be present at this early stage of recovery and nitrogen narcosis only occurs
from breathing compressed air.
