Mechanical Ventilation (NCLEX) Exam Questions And Answers Verified 100% Correct What should the nurse recognize as a factor commonly responsible for sodium and fluid retention in the patient on mechanical ventilation? a. increased release of ADH b. increased release of atrial natriuretic factor c. increased insensible water loss via the airway d. decreased renal perfusion with release of renin - ANSWER D A patient receiving mechanical ventilation is very anxious and agitated, and neuromuscular blocking agents are used to promote vasodilation. What should the nurse recognize about the care of this patient? a. the patient will be too sedated to be aware of the details of care b. caregivers should be encouraged to provide stimulation and diversion c. the patient should always be addressed and explanations of care given d. communication will not be possible with the use of neuromuscular blocking agents - ANSWER C The nurse determines that alveolar hypoventilation is occurring in a patient on a ventilator when what happens? a. the patient develops cardiac dysrhythmias b. auscultation reveals an air leak around the ET tube cuff c. ABG results show a PaCO2 of 32 mm Hg and a pH of 7.47 d. the patient tries to breathe faster than the ventilator setting - ANSWER B What plan should the nurse use when weaning a patient from a ventilator? a. decrease the delivered FIO2 concentration b. intermittent trials of spontaneous ventilation followed by ventilatory support to provide rest c. substitute ventilator support with manual resuscitation bag if the patient becomes hypoxic d. implement weaning procedures around the clock until the patient does not experience ventilator fatigue - ANSWER B A 68-yr-old male patient diagnosed with sepsis is orally intubated on mechanical ventilation. Which nursing action is most important? a. Use the open-suctioning technique. b. Administer morphine for discomfort. c. Limit noise and cluster care activities. d. Elevate the head of the bed 30 degrees. - ANSWER D The nurse is caring for a 65-yr-old man with acute respiratory distress syndrome (ARDS) who is on pressure support ventilation (PSV), fraction of inspired oxygen (FIO2) at 80%, and positive end-expiratory pressure (PEEP) at 15 cm H2O. The patient weighs 72 kg. What finding would indicate that treatment is effective? a. PaO2 of 60 mm Hg b. Tidal volume of 700 mL c. Cardiac output of 2.7 L/min d. Inspiration to expiration ratio of 1:2 - ANSWER A When planning care for a patient on a mechanical ventilator, the nurse understands that the application of positive end-expiratory pressure (PEEP) to the ventilator settings has which therapeutic effect? a. Increased inflation of the lungs b. Prevention of barotrauma to the lung tissue c. Prevention of alveolar collapse during expiration d. Increased fraction of inspired oxygen concentration (FIO2) administration - ANSWER C Which assessment information obtained by the nurse when caring for a patient receiving mechanical ventilation indicates the need for suctioning? a. The respiratory rate is 32 breaths/min. b. The pulse oximeter shows a SpO2 of 93%. c. The patient has not been suctioned for the last 6 hours. d. The lungs have occasional audible expiratory wheezes. - ANSWER A Four hours after mechanical ventilation is initiated for a patient with chronic obstructive pulmonary disease (COPD), the patients arterial blood gas (ABG) results include a pH of 7.50, PaO2 of 80 mm Hg, PaCO2 of 29 mm Hg, and HCO3 of 23 mEq/L (23 mmol/L). The nurse will anticipate the need to a. increase the FIO2. b. decrease the respiratory rate. c. increase the tidal volume (VT). d. leave the ventilator at the current settings. - ANSWER B When the nurse is weaning a patient who has chronic obstructive pulmonary disease (COPD) from mechanical ventilation, which patient assessment indicates that the weaning protocol should be discontinued? a. The patient heart rate is 98 beats/min. b. The patients oxygen saturation is 93%. c. The patient respiratory rate is 32 breaths/min. d. The patients spontaneous tidal volume is 500 mL. - ANSWER C A patient who is receiving mechanical ventilation is anxious and is fighting the ventilator. Which action should the nurse take first? a. Ventilate the patient with a manual resuscitation bag. b. Verbally coach the patient to breathe with the ventilator. c. Sedate the patient with the ordered PRN lorazepam (Ativan). d. Increase the rate for the ordered propofol (Diprivan) infusion. - ANSWER B A patient with a subarachnoid hemorrhage is intubated and placed on a mechanical ventilator. When monitoring the patient, the nurse will need to notify the health care provider if the patient develops a. oxygen saturation of 94%. b. respirations of 18 breaths/min. c. green nasogastric tube drainage. d. increased jugular vein distention (JVD). - ANSWER D A nurse is caring for a client who is experiencing respiratory distress. Which of the following early manifestations of hypoxemia should the nurse recognize? Select all that apply a. confusion b. pale skin c. bradycardia d. hypotension e. elevated blood pressure - ANSWER BE A nurse is reviewing the plan of care for a client who is receiving mechanical ventilation. Which of the following ventilator modes will increase the client's work of breathing? Select all that apply a. assist-control b. synchronized intermittent mandatory ventilation
