Assist Control (AC) (aka Volume Control) Ventilation -RNSG 2539 Exam I SAC Mobility Program
Gas Exchange Fluid & Electrolytes correct answersThe ventilator delivers a preset volume at a
preset frequency in synchrony with the patients spontaneous breathing.
Synchronized Intermittent Mandatory Ventilation (SIMV) - correct answersThe ventilator
delivers a preset volume at a preset frequency. The patient can breathe faster than the preset
rate but not slower.
Pressure Controlled Ventilation (PCV) Mode - correct answersUsed when compliance is
decreased and the patient has a continuous oxygenation problem despite a high FiO2
Pressure -Support Ventilation (PSV) - correct answersPositive pressure is applied only during
inspiration and is used in conjunction with the patient's spontaneous respiration.
Continuous Mandatory Ventilation - correct answersBreaths are delivered at a set rate per
minute and a set tidal volume.
Characterized by a ventilator that makes no effort to sense patient effort. Patient must be
sedated. The ventilator controls everything.
,Pressure Support - correct answersaugments or assists spontaneous breathing efforts by
delivering a high flow of gas to a selected pressure level early in inspiration and maintaining that
level throughout the inspiratory phase. The patient's effort determines the rate, inspiratory
flow, and tidal volume.
Noninvasive Bilateral Positive-Pressure Ventilation Mode - correct answersA non-invasive form
of mechanical ventilation, provided by means of nasal masks, prongs, or full face mask. Used in
the treatment of patients with chronic insufficiency to manage acute or chronic respiratory
failure.
Tidal Volume - correct answersThe number of ML of air to be delivered with each breath
If the patient is able to clear secretions with a cough, what action should the nurse take? -
correct answersSuction the patient only if needed.
All of the following signs and symptoms indicate to the nurse that a patient with an artificial
airway needs suctioning except? - correct answersSustained coughing
Correct Answer: *Gradual increase in PaO2*
Suspected aspiration of secretions
Rhonchi auscultated over bronchi
Patients requiring long term ventilation are converted to a tracheostomy to prevent the
complications of long term intubation with an ETT. The advantages of converting to a
tracheostomy all of the following except? - correct answersDecreased problems of airway
resistance and occlusion
Enhanced patient comfort
Correct Answer * Tracheal stenosis*
Faster weaning

26 cm at the lip. What is the nurse's priority action in this situation? - correct answersExtubate
the patient
Manually bag with Ambu bag
Call a code
Correct Answer: *Assess the patient*
Compliance refers to: - correct answersCorrect Answer: *The ability of the lungs to distend*
How fast the patient is breathing
If the alveoli are open
The lung volume
Ventilator Acquired Pneumonia (VAP) is the second most common hospital acquired infection.
Factors the increase the chance of developing VAP include which of the following except: -
