CH. 41 OXYGENATION: NURSING SKILLS
- AIRWAY AND RESPIRATORY
MANAGEMENT EXAM QUESTIONS
WITH SOLUTIONS
When refilling an oxygen tank, for which reason does the nurse disconnect the
ambulatory unit from the stationary reservoir when the hissing noise changes and
a vapor cloud begins to form?
A. to remove moisture from the oxygen system
B. to ensure an appropriate oxygen prescription
C. to prevent malfunction to the ambulatory unit
D. to prevent from improper placement of the oxygen system - correct-answer - C.
rationale: the action will prevent overfilling. Overfilling will cause the ambulatory
unit to malfunction, caused by high pressure in the tank.

When caring for a pt with a chest tube, which action by the nurse involves manual
squeezing and releasing parts of the tubing to remove visible clots?
A. milking
B. tidying
C. leveling
D. suctioning - correct-answer - A.
rationale: if there is a visible clot in the tubing, gently milking the tubing (manual
squeezing and releasing of parts of the tubing) may be indicated, but only if the pt
is at risk of further harm from the clot, such as the development of a tension
pneumothorax
Artificial oral airway - correct-answer - Prevents obstruction of the trachea by
displacement of the tongue into the oropharynx
The simplest type of artificial airway; it can be inserted easily and without
additional equipment or anesthesia

Chest tubes are used to treat which respiratory condition? - correct-answer - A
chest tube is a catheter inserted through the rib cage into the pleural space to
remove air, fluids, or blood; to prevent air or fluid from reentering the pleural
space; or to establish normal intrapleural and intrapulmonic pressures after
trauma or surgery.
Chest tubes are common after chest surgery and chest trauma and are used for
treatment of pneumothorax or hemothorax to promote lung reexpansion
For which reason would the nurse leave space to snugly fit two fingers under the
neck strap while placing the tracheostomy tube? - correct-answer - Skin necrosis
can be prevented by leaving a small gap under the neck strap
Which nursing intervention helps to ensure that a pt receives 35% O2 via Venturi
mask as prescribed?
A. adjust the barrel on the mask to the correct O2 level
B. apply an adaptor to increase humidification of the O2
C. Drain moisture condensation from the O2 tubing every hour
, 4|Page
D. Keep the flow rate high enough to keep the bag from collapsing during
inspiration - correct-answer - A
rationale: the mask contains a Venturi barrel that allows the nurse to set the mask
to the correct O2 flow rate. the mask is designed to provide a specific amount of
O2 with humidity added; an adaptor is not necessary
Which statement made by a pt's caregiver indicates successful teaching about
safety measures related to home oxygen therapy?
A. "I should lay the oxygen cylinder on the floor in an area that won't create a fall
risk"
B. "I should check the oxygen level of the portable tank before transporting the
pt"
C. "I should keep the oxygen-delivery system 5 ft away from any open flames"
D. "I should make sure the O2 tubing has no slack to prevent tangling" - correct-
answer - B.
