49 Useful Free CNA Practice Exam 2015 Questions and Answers on Acute Respiratory Distress Syndrome

What is Valsalva maneuver?

• By the mechanism that ends inspiration and starts expiration
• -reduced respiratory muscle function -reduced immune response
• A form of vagal stimulation of the cardiac conduction system in which the health care provider instructs the patient to bear down as if straining to have a bowel movement
• -mechanical ventilation to prevent complications

What is the function of a time-cycled ventilator?

• -pressure used by the ventilator to deliver a set tidal volume at a given lung compliance -highest pressure reached during inspiration
• -push air into the lungs until a preset volume is delivered - a constant tidal volume is delivered regardless of the pressure needed to deliver the tidal volume -set pressure limit prevents excessive pressure from being exerted on the lungs
• Number of ventilator breaths delivered per minute
• -push air into the lungs until a preset time has elapsed -tidal volume and pressure vary, depending on needs of the patient and type of ventilator

What nursing management is used with patients on a ventilator?

• By the mechanism that ends inspiration and starts expiration
• -mechanical ventilation to prevent complications
• Irreversible -prevent sepsis, pneumonia, MODS, patient from ventilator
• -always assess the patient first, ventilator second -monitor patient response -manage ventilator system -prevent complications

What are the intrinsic causes of alveolar-capillary membrane injured?

• -sepsis -shock
• Stages 2-3
• Versed
• Pseudomonas

What other type of complications can occur with ventilator systems?

• Positive pressure exerted during expiration
• -reduced respiratory muscle function -reduced immune response
• -hypotension -fluid retention -Valsalva maneuver
• -GI -nutritional -infections -muscle deconditioning -ventilator dependence

What is the tidal volume on the ventilator?

• Lubricates and decreases surface tension
• Number of ventilator breaths delivered per minute
• The volume of air the patient receives with each breath, as measured on either inspiration or expiration
• -endotracheal intubation -nasotracheal intubation -tracheal intubation

What is positive-pressure mechanical ventilation?

• During inspiration, pressure is generated that pushes air into the lungs and expands the chest
• -GI -nutritional -infections -muscle deconditioning -ventilator dependence
• -arterial oxygen pressure (PaO2) remains low with a FiO2 of 50-70% or greater
• Damage to the lungs by excess volume delivered to one long or the other

What interventions are appropriate for a patient with acute respiratory distress syndrome?

• -GI -nutritional -infections -muscle deconditioning -ventilator dependence
• Provides noninvasive pressure support ventilation by nasal mask for facemask
• -mechanical ventilation to prevent complications
• -ET intubation, conventional mechanical ventilation with PEEP or CPAP -drug and fluid therapy -nutrition therapy -case management

What is a hallmark sign of recovery for a patient with acute respiratory distress syndrome?

• 40L/min
• Diuresis
• Tracheostomy
• Pseudomonas

What is volutrauma?

• Damage to the lungs by excess volume delivered to one long or the other
• Not responding to high concentration of O2
• How fast each breath is delivered
• Number of ventilator breaths delivered per minute

What does an increased PIP reading mean?

• Increased airway resistance in patient or ventilator tubing, increased secretions -pulmonary edema -decreased pulmonary compliance
• -always assess the patient first, ventilator second -monitor patient response -manage ventilator system -prevent complications
• Patchy infiltrate form from increased pulmonary edema
• Peak airway (inspiratory) pressure

What do corticosteroids cause in patients with acute respiratory distress syndrome?

• -decreased WBC -decreased inflammation -stabilize capillary membranes
• Lubricates and decreases surface tension
• -mechanical ventilation to prevent complications
• Reduce tracheal and vocal cord damage

What occurs during the early stages of acute respiratory distress syndrome?

• Diuresis
• Fluid in interstitial spaces
• Maintain fluid balance
• Acute lung injury

What are the types of intubation?

• Reduce tracheal and vocal cord damage
• Removal of the endotracheal tube
• -endotracheal intubation -nasotracheal intubation -tracheal intubation
• -mechanical ventilation to prevent complications

Why is the oxygen warmed and humidified?

• Prevent mucosal damage
• Maintain fluid balance
• Patient with sleep apnea
• Pseudomonas

What is the normal prescribed PEEP level?

• Damage to lungs by positive pressure
• -5-15cm H2O to promote adequate oxygenation -monitored on the peak airway pressure dial
• -hypotension -fluid retention -Valsalva maneuver
• Continuous positive airway pressure

What medication is used for endotracheal tube placement?

• Versed
• Acute lung injury
• -sepsis -shock
• 40L/min

What is an important warning about positive end-expiratory pressure?

• Positive pressure exerted during expiration
• Irreversible -prevent sepsis, pneumonia, MODS, patient from ventilator
• Fluid shifts into the alveoli (wet alveoli - crackles in lungs)
• Lower the FiO2 delivered whenever possible because prolonged use of a high FiO2 can damage lungs from the toxic effects of oxygen

What causes refractory hypoxemia?

• Removal of the endotracheal tube
• Not responding to high concentration of O2
• Patient with sleep apnea
• Acute respiratory distress syndrome

What is bi-level positive airway pressure?
