NUR210 MOD1: Mechanical Vent
Exam Questions and Answers
100% pass
Definition—ANSWER-Mechanical ventilation (MV) is the use of a ventilator to assist or
completely replace spontaneous breathing when a patient cannot breathe effectively on
their own. It ensures adequate oxygenation and ventilation.
Mech Vent: Indications—ANSWER--Acute Respiratory Failure (ARF)
-Chronic Respiratory Failure
-Airway protection (↓ LOC, aspiration risk)
-Surgical procedures
-Severe hypoxemia
-Severe hypercapnia
Mech Vent: goals—ANSWER--Support the patient until the underlying cause is corrected
-Improve ventilation and perfusion
, -Decrease work of breathing
-Maintain adequate oxygenation and CO₂ removal
Mech Vent: How it works—ANSWER--Positive Pressure Ventilation: Air is pushed into the
lungs under pressure
-Requires an artificial airway: Endotracheal Tube (ETT) (Short-term use) or Tracheostomy
Tube (Long-term use)
What is an ETT?—ANSWER--Goes through the nose or mouth and into the trach
-Has a cuff at the end that prevents air from coming back up.
-Must be inserted equally, so both lungs inflate.
What should the nurse monitor for with an ETT tube?—ANSWER--Pressure injury where the
tube sits around the nose/mouth
What is a trach?—ANSWER--Goes through the neck and into the lungs
When are the tubes cuffed?—ANSWER--At all times when a patient is on an MV.
-If the patient is doing well and trying to speak, they are weaned off the vent and the trach is
uncuffed.
What happens when a trach patient is trying to talk? what if they need to be suctioned?—
ANSWER--If they are trying to talk, switch the inner cannula for a fenestrated collar (has a
hole in it)
