Cooper: Foundation of Nursing, 9th Edition
MULTIPLE CHOICE
1. The wife of a patient with a cuffed tracheostom y asks why the cuff is
inflated intermittently. What is the purpose of the inflated cuff?
a. Prevent regurgitation after meals.
b. Hold the trachea open until it is completely healed.
c. Dilate the tracheal opening for passage of secretions.
d. Prevent aspiration when eating.
ANS: D
The cuff is inflated to prevent aspiration while eating or when cleanin g
the tracheostom y tube.

2. Which of the following is an appropriate nursing meas ure when
performing tracheostom y care?
a. Wear clean gloves.
b. Insert the catheter without suction.
c. Suction for 1 minute before removing the catheter.
d. Place the used catheter in a plastic shield for later use.
, ANS: B
Insertion of the suction catheter without suction reduces the probabilit y
of tissue injury. Sterile gloves should be used for tracheostomy care.

3. An 80-year-old male patient has been admitted to the acute care facilit y
with the diagnosis of pneumonia. He is receiving ox ygen via nasal cannula
at 2 L/min. The nurse assesses respirations at 24/min, PaO2 level 88 mm
Hg, and pink skin tone. What action should the nurse implement?
a. Notify the health care provider. (Space added)
b. Increase ox ygen to 4 L/min.
c. Record PaO2 level.
d. Administer nebulizer treatment.
ANS: C
The nurse would document PaO2 level. Normal arterial oxygen levels
sometimes decrease with age, but not usuall y low enough to fall
outside the normal range. It may be possible for an 80 -year-old person
to have an arterial partial pressure oxygen (PaO2) level (the amount of
oxygen found in the arterial circulation) between 80 and 85 mm Hg
(normal range is 80 to 100 mm Hg) without experiencing significant
alterations in health.
