Pre-Employment Exam CCU 1. The pulmonary artery occlusive [wedge] pressure (PAOP) reflects pressure in the: a. Right atrium b. Left ventricle c. Left atrium d. Pulmonary artery 2. What is normal pulmonary artery pressure? a. 10-20 mean 5-10 0-4 b. 36-45 mean 31-33 21-23 c. 21-30 mean 11-20 5-15 d. 31-35 mean 21-30 16-20 3. You receive the following ABGs: pH 7.40 pO2 98 mm Hg PCO2 38 mm Hg HCO3 25 mEq What do these results reflect? a. Normal values b. Metabolic alkalosis c. Metabolic acidosis d. Respiratory compensation 4. What is the goal of treatment of cardiogenic shock? a. Lower the BUN b. Increase the afterload c. Decrease fluid volume d. Increase cardiac output 5. How would the nurse best assess proper positioning of an endotracheal tube? a. Check the respiratory rate on the ventilator b. Listen for bilateral breath sounds c. Ask a coworker to check for proper positioning d. Check chest expansion 6. How long should direct pressure generally be applied after removal of an arterial catheter? a. Until a pressure dressing is applied b. Until blood stops oozing from the site c. For 5 to 10 minutes d. For a full minute 7. Identify the rhythm: _______________________________________________________________ 8. Identify the rhythm: _____________________________________________________________ 9. Identify the rhythm: ______________________________________________________________ 10. Normally, a QRS complex wider than 0.12 seconds indicates: a. Second degree heart block b. Bundle branch block c. Normal sinus rhythm d. Myocardial infarction 11. Atrial flutter is: a. Dangerous because the ventricular rate could suddenly increase b. Dangerous because it could progress to a second degree heart block c. Normal after an MI d. Not usually something to worry about for most people 12. When using a monophasic defibrillator, what is the correct energy setting for the first defibrillation for the patient with ventricular fibrillation? a. 120 b. 25-30 c. 420 d. 360 13. This is the most important step in preventing central venous catheter sepsis: a. Use of a transparent membrane dressing b. Using antibiotic ointment under the dressing c. Thorough hand washing d. Changing the catheter weekly 14. The physician orders a heparin drip to run at 12 units/hr. The patient weighs 80kg and your IV has 25,000 units of heparin in 250ml of D5W. How many ml/hr will you set the pump for? a. 10.2 ml/hr b. 9.6 ml/hr c. 5.3 ml/hr d. 7.5 ml/hr 15. What drug would you use to treat this rhythm initially? a. b. c. d. Atropine Amiodarone Lidocaine Epinephrine
