TMC EXAM 4 with verified Answers Explanation: Right-sided preload is another name for CVP (central venous pressure). Peripheral edema is one of the signs associated with right heart failure, which results in an elevated CVP with a normal or low pulmonary artery pressure (PAP), a.k.a. right ventricular afterload. A ventilator-dependent patient is scheduled for an MRI, which will require a transport of 90 minutes. The patient is receiving humidification with a heated- humidification system. A transport ventilator is available. How should a respiratory therapist assure that humidification will be provided to the patient during the MRI procedure? A. Provide a pass-over humidifier B. Provide an HME C. Provide ventilation with a manual resuscitator D. Use the same humidification system in use on the primary ventilator - ANSWERS-The correct answer is : B Explanation: A heat moisture exchanger (HME) is appropriate for a transport of only 90 min. Furthermore, the scenario does not suggest that the patient has thick, retained secretions; therefore an HME may be applied.
