Mechanical Ventilation Chapter 5 Questions and Answers with Certified Solutions

Mechanical Ventilation Chapter 5 Questions and Answers with Certified Solutions A nurse is caring for a patient on mechanical ventilation who is in acute respiratory distress. The nurse notes that the patient's tidal volume is set to 500 mL, but the peak inspiratory pressure is rising. What should the nurse do first? a) Increase the tidal volume to improve ventilation b) Assess the airway for obstructions or kinks in the endotracheal tube c) Decrease the PEEP level to lower airway pressure d) Increase the respiratory rate to assist with ventilation A nurse is caring for a patient on mechanical ventilation with volume control. The nurse is concerned that the patient may develop ventilator-associated lung injury. Which of the following interventions should the nurse prioritize to minimize this risk? a) Increase the respiratory rate to ensure adequate ventilation b) Use lower tidal volumes to prevent barotrauma and volutrauma c) Increase the PEEP to improve oxygenation d) Adjust the FiO2 to maintain adequate oxygen saturation levels 2 A nurse is caring for a patient receiving mechanical ventilation in the pressure-controlled mode. Which of the following is the primary benefit of pressure-controlled ventilation? a) It guarantees a fixed tidal volume with each breath b) It helps prevent barotrauma by limiting the pressure delivered to the lungs c) It allows the ventilator to automatically adjust the tidal volume based on the patient’s lung compliance d) It increases the rate of oxygenation by delivering higher pressures with each breath A nurse is monitoring a patient who is receiving mechanical ventilation with positive end- expiratory pressure (PEEP). The nurse notes that the patient is developing signs of increased intracranial pressure (ICP). Which of the following actions should the nurse take? a) Decrease the PEEP level to reduce the risk of increasing ICP b) Increase the PEEP to improve oxygenation c) Increase the tidal volume to assist with ventilation d) Decrease the respiratory rate to allow for longer exhalation A nurse is caring for a patient with acute respiratory failure who is on a mechanical ventilator in the assist-control (AC) mode. The nurse notices that the patient is experiencing signs of ventilator-associated pneumonia (VAP). Which of the following is the most effective intervention to prevent VAP? 3 a) Administer antibiotics as prescribed b) Elevate the head of the bed to 30–45 degrees and provide regular oral care c) Increase the PEEP to improve oxygenation d) Sedate the patient to reduce the work of breathing A nurse is caring for a patient who is receiving mechanical ventilation in the synchronized intermittent mandatory ventilation (SIMV) mode. Which of the following is true about SIMV mode? a) The ventilator delivers a set number of breaths and no spontaneous breaths b) The ventilator completely controls the patient’s breathing pattern c) The ventilator delivers a set number of mandatory breaths, but the patient can initiate additional spontaneous breaths d) The ventilator adjusts the tidal volume based on the patient's effort A nurse is monitoring a patient on mechanical ventilation who is receiving assist-control ventilation. The nurse observes that the patient is trying to breathe faster than the ventilator settings. Which of the following best describes the ventilator's response? a) The ventilator will assist the patient's spontaneous breaths but will still deliver the set mandatory breaths 4 b) The ventilator will stop assisting the patient if the spontaneous rate exceeds the set rate c) The ventilator will not deliver any breaths until the patient’s spontaneous breathing rate decreases d) The ventilator will increase the tidal volume to compensate for the increased breathing rate A nurse is caring for a patient who is on mechanical ventilation in a volume-controlled mode. The patient’s oxygen saturation level is decreasing despite appropriate tidal volume and rate settings. What is the nurse's next step? a) Increase the tidal volume to improve ventilation
