A 56-year-old patient is admitted to the critical care unit with acute respiratory distress syndrome (ARDS). The patient has been intubated and is mechanically ventilated
The patient is becoming increasingly agitated, and the high-pressure alarm on the ventilator has been frequently triggered. The nurse's first intervention for this patient would be to a. administer midazolam 5 mg by intravenous push immediately. b. assess the patient to see if a physiologic reason exists for his agitation. c. obtain a stat arterial blood gas level; his agitation indicates he is becoming increasingly hypoxic. d. apply soft wrist restraints to keep him from pulling out the endotracheal tube.

Identify the difference between preload and afterload.
A. Preload is the amount of blood returning to the heart (venous return). Afterload is the force (force of ventricular contraction) that the heart must generate in order to overcome vascular resistance (open the aortic valve) and eject blood out of the left ventricle. B. Preload is the force (force of atrial contraction) that the heart must generate in order to eject blood out of the right ventricle. Afterload is the amount of blood ejected by the left ventricle. C. Preload is the force (force of ventricular contraction) that the heart must generate in order to overcome vascular resistance (open the aortic valve) and eject blood out of the left ventricle. Afterload is the amount of blood returning to the heart (venous return). D. None of the above are correct.
