Exam 9: Ventilatory Assistance

A patient's status worsens and needs mechanical ventilation.The pulmonologist wants the patient to receive 10 breaths/min from the ventilator but wants to encourage the patient to breathe spontaneously between the mechanical breaths at his own tidal volume.This mode of ventilation is called

The nurse is caring for a patient who is mechanically ventilated.As part of the nursing care,the nurse understands that

The primary mode of action of neuromuscular blocking agents is

Select all of the factors that may predispose the patient to respiratory acidosis.

Oxygen saturation (SaO₂)represents

The nurse is caring for a patient whose ventilator settings include 15 cm H₂O of positive end-expiratory pressure (PEEP).What complication does the nurse assess the patient for?

The nurse notes that the patient's arterial blood gas levels indicate hypoxemia.The patient is not intubated and has a respiratory rate of 22 breaths/min.The nurse's first intervention to relieve hypoxemia is to:

A PaCO₂ of 48 mm Hg is associated with

A patient is being mechanically ventilated in the synchronized intermittent mandatory ventilation mode at a rate of 4 breaths/min.His spontaneous respirations are 12 breaths/min.He receives a dose of morphine sulfate,and his respirations decrease to 4 breaths/min.What adjustments may need to be made to the patient's ventilator settings?

A patient is admitted to the progressive care unit with a diagnosis of community-acquired pneumonia.The patient has a history of chronic obstructive pulmonary disease and diabetes.A set of arterial blood gases obtained on admission without supplemental oxygen shows pH 7.35; PaCO₂ 55 mm Hg; bicarbonate 30 mEq/L; PaO₂ 65 mm Hg.These blood gases reflect:

The nurse is caring for a mechanically ventilated patient and notes the high pressure alarm sounding.The nurse cannot quickly identify the cause of the alarm and notes the patient's oxygen saturation is decreasing and heart rate and respiratory rate are increasing.The nurse's priority action is to

The amount of effort needed to maintain a given level of ventilation is termed

A patient is admitted to the cardiac surgical intensive care unit after cardiac surgery.Four hours after admission to the surgical intensive care unit at 4 PM,the patient has stable vital signs and normal arterial blood gases (ABGs),and is placed on a T-piece for ventilatory weaning.The following information pertains to the 1900 assessment. What action by the nurse is best?

Positive end-expiratory pressure (PEEP)is a mode of ventilatory assistance that produces the following condition:

The provider orders the following mechanical ventilation settings for a patient who weighs 75 kg.The patient's spontaneous respiratory rate is 22 breaths/min.Which arterial blood gas abnormality may occur if the patient continues to be tachypneic at these ventilator settings? Settings: Tidal volume: 600 mL (8 mL per kg) FiO₂: 0.5 Respiratory rate: 14 breaths/min Mode assist/control Positive end-expiratory pressure: 10 cm H₂O

Current guidelines recommend the oral route for endotracheal intubation.The rationale for this recommendation is that nasotracheal intubation is associated with a greater risk for

The nurse is caring for a patient with an endotracheal tube.The nurse understands that endotracheal suctioning is needed to facilitate removal of secretions and that the procedure

A patient is having difficulty weaning from mechanical ventilation.The nurse assesses the patient for which potential cause of this difficult weaning?

The nurse is caring for a mechanically ventilated patient and responds to a high inspiratory pressure alarm.Recognizing possible causes for the alarm,the nurse assesses for which of the following?

The nurse is assisting with endotracheal intubation and understands that correct placement of the endotracheal tube in the trachea would be identified by which of the following?
