Exam 2: Mechanical Ventilation NCLEX

Questions And Answers With Guaranteed Pass!!a - Answer The purpose of adding PEEP to positive pressure ventilation is to

• increase functional residual capacity and improve oxygenation
• increase FIO2 in an attempt to wean the patient and avoid O2 toxicity
• determine if the patient is in synchrony with the ventilator or needs to be paralyzed
• determine is the patient is able to be weaned and avoid the risk of

pneumomediastinum c - Answer The nursing management of a patient with an artificial airway includes

• maintaining the ET tube cuff pressure at 30 cm H20
• routine suctioning of the tube at least every 2 hours
• observing for cardiac dysrhythmias during suctioning
• preventing tube dislodgment by limiting mouth care to lubrication of the lips

c - Answer The nurses monitors the patient with positive pressure mechanical ventilation for

• paralytic ileus because pressure on the abdominal contents affects bowel motility
• diuresis and sodium depletion because of increased release of atrial natriuretic

peptide

• signs of cardiovascular insufficiency because pressure in the chest impedes venous

return

• respiratory acidosis in a patient with COPD because of alveolar hyperventilation and

increased PaO2 levels c - Answer A comatose patient with a possible cervical spine injury is intubated with a nasal ET tube. The nurse recognizes that what is a disadvantage of a nasal ET tube in comparison with an oral ET tube?

• requires the placement of a bite block
• is more likely to cause laryngeal edema
• requires greater respiratory effort in breathing
• requires the placement of an additional airway to keep the trachea open

a - Answer In preparing a patient in the ICU for oral ET intubation, what should the nurse do that is most important for successful intubation?

• place the patient supine with the head extended and the neck flexed
• tell the patient that the tongue must be extruded while the tube is inserted
• position the patient supine with the head hanging over the edge of the bed to align

the mouth and trachea 1 / 2

Questions And Answers With Guaranteed Pass!!

• inform the patient that while it will not be possible to talk during insertion of the tube,

speech will be possible after it is correctly placed c - Answer The nurse uses the minimal occluding volume technique to inflate the cuff on an ET tube to minimize the incidence of what?

• infection
• hypoexmia
• tracheal damage
• accidental extubation

c - Answer When should the nurse suction a patient's ET tube?

• when the patient has peripheral wheezes in all lobes
• when the patient has not been suctioned for the past 2 hours
• when the nurse auscultates adventitious sounds over the central airways
• when the nurse assesses a need to stimulate the patient to cough and deep breathe

c - Answer What nursing care is included for the patient with an ET tube?

• check the cuff pressure every hour
• keep a tracheosotmy tray at the bedside
• hyperoxygenate before and after suctioning
• reuse the suction catheter at the bedside for 24 hours

d - Answer While suctioning the ET tube of a spontaneously breathing patient, the nurse notes that the patient develops bradycardia with PVCs. What should the nurse do first?

• stop the suctioning and assess the patient for spontaneous respirations
• attempt to resuction the patient with reduced suction pressure and pass time
• stop the suctioning and ventilate the patient with slow, small-volume breaths using a

bag-valve-mask

• stop suctioning and ventilate the patient with a BVM device with 100% oxygen until

the HR returns to baseline a d - Answer What precautions should the nurse take during mouth care and repositioning of an oral ET tube to prevent and detect tube dislodgment? Select all that apply

• confirm bilateral breath sounds after care
• use suction pressures less than 120 mm Hg
• use humidified inspired gas to help thin secretions
