FCCS EXAM QUESTIONS AND ANSWERS

What is the most important sign in a critically ill pt? Why? - Answer- Tachypnea Indicates metabolic acidosis (often w/ respiratory alkalosis compensation) A pt misses dialysis for a few days and comes in with fluid overload. He's tachycardic and tachypneic. On physical exam, you find JVD, pulsus paradoxus (20 mmHg drop during inspiration), and HoTN (80/40) with distant, muffled heart sounds. Lungs are clear to auscultation. What is the dx? - Answer- Cardiac tamponade; obstructive shock If a pt has a thyromental distance of 2 cm, what can you expect about their airway? - Answer- Difficult airway w/ an anteriorly displaced larynx A COPD pt comes in with difficulty breathing. He then becomes apneic and unresponsive. How would you ventilate this pt? - Answer- BVM A pt arrives after falling from a ladder and has a frontal laceration. On examination, you find papilledema and labored breathing w/o being able to clear secretions. What is your biggest concern when intubating this pt? - Answer- Cerebral edema/increasing ICP Intubation tends to cause an increase in ICP. Administer lidocaine prior to intubation to inhibit vagal stimulation. An ESRD pt w/ hyperkalemia develops dyspnea and requires intubation. Which paralytic agent/NMB should you avoid and why? - Answer- Succinylcholine Worsens hyperkalemia A pt is admitted after an OD. He starts to have apneic episodes and his SpO2 is dropping. You place him on a non-rebreather mask w/ 100% O2, yet his SpO2 remains at 80%. Why is it not being corrected? Then, if you try a BVM and it also fails, and video laryngoscopy is unavailable, what is your next best choice for an airway? - Answer- The pt is having apneic episodes, which means that administering high-flow O2 will be ineffective. Choose an LMA if the BVM fails. What intervention improves outcomes with ROSC after cardiac arrest? - Answer- Targeted temperature management. 32-36 C
