NUR 431L (AIRWAY) FINAL EXAM
QUESTIONS AND ANSWERS
Signs of cardiovascular insufficiency because pressure in the chest impedes venous
return - Answer-The nurse monitors the patient with positive pressure mechanical
ventilation for:
Lung compliance - Answer-tells us how easy it is for pt to breath and relax; we can
measure this on a mechanical ventilator
Static lung compliance - Answer-the compliance of the lower airways and the alveoli;
the change in pressure over the change in corrected or your exhaled tidal volume
PPV Pressure ventilation - Answer-peak inspiratory pressure is predetermined and the
tidal volume delivered to patient varies based of selected pressure & compliance and
resistance factors; must be careful to prevent unplanned hyperventilation or
hypoventilation; used for the critically ill
•CV:
-there is increased intrathoracic pressure --> compression of thoracic vessels -->
decreased PL, AL, CO
•Pulmonary:
-Barotrauma: patients w/ noncompliant lungs more @ risk; can have alveolar HYPER or
HYPOtension,
-VAP: minimize sedation, daily awake trials, oral hygiene, weening
•F&E imbalance:
-caused by decreased UOP and increased retained sodium (hypernatremia)
•GI:
-stress ulcers, C. diff - Answer-Caring for intubated patient:
Every 24 hours and PRN - Answer-The correct frequency for tracheostomy care is:
Stoma condition, type and size, amount of secretions (all answers are correct) -
Answer-Documentation for a patient receiving routine tracheostomy tube care should
include:
Continuous wave form and capnography - Answer-What is the most reliable method of
confirming and monitoring correct placement of an endotracheal tube?
10 breaths per minute - Answer-What is the proper ventilation rate for a patient in
cardiac arrest who has an advanced airway in place?
