  1. The nurse is caring for a patient who has been on a mechanical ventilator for several days. Which of the following weaning parameters would tell the nurse whether or not the patient has enough muscle strength to breath w/o assistance?

    A. Tidal volume
    B. Forced vital capacity
    C. Minute ventilation
    D. Negative inspiratory force
    • D. Negative inspiratory force

    The negative inspiratory force (NIF) measures inspiratory muscle strenth. Tidal volume, vital capacity, and minute ventilation assess the patient's respiratory endurance.
  2. When planning care for the partient on a mechanical ventilator, the nurse understands that the application of PEEP to the ventilator settings has which of the following therapeutic effects?

    A. Increased inflation of the lungs
    B. Increased FiO2 administration
    C. Prevention of barotrauma to the lung tissue
    D. Prevention of aveolar collapse during expiration
    D. Prevention of aveolar collapse during expiration

    PEEP is positive pressure that is applied to the airway during exhalation. The postive pressure prevents the alveoli from collapsing, improving oxygenation and enabling a reduced FiO2 requirement.
  3. A family member asks the nurse what SIMV means on the settings of the mechanical ventilator attached to their loved one. Which of the following statements best describes this mode of ventilation?

    A. SIMV is a mode that allows your loved one to breathe on their own while recieving a pre-set number of breaths from the ventilator. Your loved one can breathe as much or as little as they want beyond what the ventilator will breathe for them.
    B. SIMV is a mode that allow the ventilator to totally control breathing of your loved one. It will prevent your loved one from hypervenilating or hypoventilating, thus insuring the best oxygenation that we can.
    C. SIMV is a mode that allows your loved one to breathe on their own, but the ventilator will control how deep a breath your loved one will recieve. The ventilator can sense when your loved one wants a breath and will deliver it.
    D. SIMV provides additional inspiratory pressure so that your loved one does not have to work as hard to breath oxygenation and quicker recovery with less complications.
  4. A. SIMV is a mode that allows your loved one to breathe on their own while recieving a pre-set number of breaths from the ventilator. Your loved one can breathe as much or as little as they want beyond what the ventilator will breathe for them.
    • SIMV stands for sychonized intermittent mandatory ventilation, a mode of ventilation where the ventilator delivers a preset todal volume at a preset frequency in synchrony with the patient's spontaneous breathing. Between ventilator-delivered breaths, the patient is able to breathe spontaneously, recieving the preset FiO2ut self regulating the rate and depth of those breaths.
