CEN Post Test Part 2 Answers
1. C - CPR and defibrillation are the priorities in VF, along with finding the cause of the arrest and epinephrine. (PALS
pgs. 89-92)
2. C – Evidence should be placed in paper, not plastic bags. The other options are correct. (Sheehy pgs. 596-98)
3. B – EMTALA is a component of COBRA which states that a qualified provider must perform a medical screening
exam and treatment to stabilize emergency medical conditions on all patients who present requesting emergency
care (Sheehy pgs. 9-11)
4. B – The difference between START and JumpSTART triage criteria is that 5 rescue breaths are to be provided to a
pediatric patient who is not breathing but has a palpable pulse, and breathing is to be reassessed prior to categorizing
the patient as dead/dying. If this patient begins breathing on her own after 5 rescue breaths, she would be
categorized as immediate. (ENPC pg. 349)
5. D – The KB serum test detects fetal red cells in the maternal circulation, used to predict abruptio placentae. It is
important in determining the need to administer Rh immune globulin when the mother is Rh negative, and the fetus
is Rh positive. (TNCC pg. 299)
6. C – The person who approaches the family about donation must be a trained requester or local organ procurement
representative. Early notification gives the OPO representative adequate time to prepare the family for the request to
donate a loved one’s organs or tissue. (Sheehy pg. 142, 146 and TNCC pg. 334)
