A patient is receiving assist-control (A/C) ventilation. Which statement best describes how breaths are delivered?

A
The patient must initiate every breath, and the ventilator provides pressure support only.
B
The ventilator provides a minimum rate, and patient-triggered breaths also receive the set mandatory breath.
C
The ventilator delivers only fixed breaths and does not respond to patient effort.
D
The patient breathes spontaneously with continuous baseline pressure and no assisted breaths.

A
Delivered tidal volume may decrease.
B
Delivered tidal volume remains fixed.

A low-pressure alarm sounds and the patient’s oxygen saturation begins to fall. What is the priority action?

A
Assess the patient and promptly check for a disconnected or leaking circuit or displaced airway; summon help and use a manual resuscitation bag if needed and within scope and protocol.
B
Increase the ventilator’s tidal-volume setting without checking the patient or circuit.
C
Wait for the next scheduled ventilator check.
D
Turn off the alarm because low-pressure alarms are rarely urgent.

A commonly used lung-protective approach for a patient with ARDS starts near what tidal volume per kilogram of predicted body weight? Enter the numeric value in mL/kg.

True or false

1 point

In SIMV, mandatory breaths are synchronized with the patient’s effort, while spontaneous breaths between mandatory breaths may receive pressure support.

True
B
False

Which statement correctly describes volume-controlled ventilation?

A
The ventilator targets a set tidal volume, while airway pressure may vary.
B
The ventilator targets inspiratory pressure, while delivered tidal volume may vary.
C
The ventilator keeps both airway pressure and tidal volume fixed.
D
The ventilator provides no targeted setting and requires only spontaneous patient effort.

After a ventilator adjustment, an arterial blood gas shows rising PaCO₂ with falling pH. Which interpretation is most appropriate?

A
The patient may be under-ventilated; promptly report the trend and review the patient and ventilator plan with the responsible clinician.
B
The patient has improved ventilation, so no follow-up is needed.
C
The patient is necessarily receiving too much oxygen.
D
PEEP should be independently stopped.

During routine care of a patient receiving invasive mechanical ventilation, which assessment approach is most appropriate?

A
Check only the displayed ventilator settings and disconnect the patient for each assessment.
B
Assess respiratory effort, chest movement, breath sounds, oxygenation, synchrony, airway position and securement, secretions, circuit, and relevant trends; verify cuff pressure with a manometer according to policy.
C
Deflate the endotracheal-tube cuff at regular intervals without an order and rely on oxygen saturation alone.
D
Assess the airway and ventilator, but never check cuff pressure with a manometer.

A patient coughs as a high-pressure alarm sounds, and peak inspiratory pressure has increased. What is the nurse’s best initial response?

A
Silence the alarm and leave the room to obtain a new ventilator.
B
Assess the patient and airway, then check for an obstructed or kinked tube or circuit and secretions; call for help if the problem persists or the patient is unstable.
C
Lower the high-pressure alarm limit until the alarm stops.
D
Disconnect the ventilator routinely and wait for the patient to recover.

Which statement best describes how ventilator settings affect gas exchange?

A
FiO₂ and PEEP are key settings affecting oxygenation; respiratory rate and tidal volume influence minute ventilation and carbon dioxide removal.
B
FiO₂ and PEEP directly correct elevated PaCO₂ in the same way as respiratory rate and tidal volume.
C
PEEP is used only to reduce PaCO₂, and FiO₂ has no role in oxygenation.
D
Respiratory rate affects oxygenation only, while FiO₂ determines carbon dioxide removal.
