Mechanical Ventilation NUR 2712C
Exam Questions & Answers (Grade
A+)
Which assessment finding obtained by the nurse when caring for a
patient receiving mechanical ventilation indicates the need for
suctioning?
а. The patients oxygen saturation is 93%.
b. The patient was last suctioned 6 hours ago.
c. The patients respiratory rate is 32 breaths/minute.
d. The patient has occasional audible expiratory wheezes. -
correct answer ✅ANS: C
The increase in respiratory rate indicates that the patient may have
decreased airway clearance and requires suctioning.
Suctioning is done when patient assessment data indicate that it is
needed, not on a scheduled basis.
Occasional expiratory wheezes do not indicate poor airway
clearance, and suctioning the patient may induce bronchospasm
and increase wheezing.

Exam Questions & Answers (Grade
A+)
An oxygen saturation of 93% is acceptable and does not suggest
that immediate suctioning is needed.
The nurse notes thick, white secretions in the endotracheal tube
(ET) of a patient who is receiving mechanical ventilation.
Which intervention will be most effective in addressing this
problem?
a. Increase suctioning to every hour.
b. Reposition the patient every 1 to 2 hours.
c. Add additional water to the patients enteral feedings.
d. Instill 5 mI of sterile saline into the ET before suctioning. -
correct answer ✅ANS: C
Because the patients secretions are thick, better hydration is
indicated.
Suctioning every hour without any specific evidence for the need
will increase the incidence of mucosal trauma and would not
address the etiology of the ineffective airway clearance.

Instillation of saline does not liquefy secretions and may decrease
the SpOz.
Repositioning the patient is appropriate but will not decrease the
thickness of secretions.
Four hours after mechanical ventilation is initiated for a patient
with chronic obstructive pulmonary disease
(COPD), the patients arterial blood gas (ABG results include a pH of
7.51, Pa02 of 82 mm Hg, PaCO2 of 26 mm Hg, and HCO3 of 23
mEg/I (23 mmolL).
The nurse will anticipate the need to
a. increase the FIO2.
b. increase the tidal volume.
c. increase the respiratory rate.
d. decrease the respiratory rate. -
