Question 1
Which setting on a ventilator would require a nursing intervention to improve the outcome for a 60-kg patient with acute lung injury (ALI)?
◦ Respiratory rate = 15 per minute, when the CO
2 levels are elevated
◦ FiO
2 = 0.30 or 30%
◦ Inspiratory:Expiratory ratio (I:E) = 1:2
◦ Tidal volume (V
T) = 900 mL
Question 2
Which statement made by a new graduate nurse about invasive mechanical ventilation techniques is incorrect and requires additional teaching?
◦ "Assist control mode refers to the patient receiving a set total lung capacity (TLC), but the rate can be modified by the patient's own rate of breathing."
◦ "Continuous positive airway pressure will increase the residual capacity and keep the alveoli open. Rate and volume are controlled by the patient. This is one step in the weaning process."
◦ "Synchronized intermittent mandatory ventilation (SIMV) refers to the patient setting an independent rate but limited tidal volume based on the patient's own strength. A minimum rate is also used as a backup to prevent hypoventilation."
◦ "Total control mode controls both the rate and volume that are preset and delivered without the machine responding to any of the patient's own breaths."
The nurse assesses the patient's ability to use the walker correctly
