 Welcome to Nursing School Explained and this final and fifth video of the nursing process series where we're going to look into more detail into the evaluation phase of the nursing process. So during the evaluation we examine the nursing care that we've provided and we basically get feedback how we have done getting our patient better. So we compare the achieved effect with the patient goal and expected outcomes. We will reassess our patient by performing a physical assessment, looking at the vital signs and any pertinent lab and diagnostic data that we have already looked at in the assessment phase but now we see how this compares to the initial data that we've gathered. And then we're going to evaluate if the problem is the same, has it got better or has it got worse. Of course the goal is always to get the patient better and then the important part here is to recognize any unmet goals. Now if we identify that there are some goals that we haven't met then we have to maybe go back and revise the plan of care either revise the goal or reassess and find out what other problems there might be or revise the interventions if the interventions that we have taken didn't get us the expected outcome and didn't have us meet the patient goal. Now if this happens if we have to revise the plan of care we basically go back to the steps of the nursing process. We reassess the patient, we redefine the goals, redefine the priorities, reestablish the goals, reformulate the interventions and reevaluate the plan of care. You can see everything is labeled here steps one through five which basically goes through the nursing process again. One after the other will just methodically follow the process until we arrive back at the reassessment. Now if we apply this evaluation phase to the example that we've been following with the patient's problem being the oxygenation and our goal was to maintain the oxygen saturation greater than 95 percent then we've taken our interventions. Now for the evaluation if our O2 status between 95 and 97 percent during our shift then we have met our goal and we come back here and we say the patient is better check that off and move on to the next problem that we have identified. However scenario number two if we'll come back here and the O2 set now has been 93 percent that means we haven't made our goal of greater than 95 percent during the shift so now we have to go back and reassess the patient and go through all the different steps. So maybe now during the reassessment I go back and I assess all these physical assessment findings as well as the labs and I find out that the patient's hemoglobin and hematocrit are 8 and 25 which will mean that the patient is anemic. Now if the patient doesn't have enough oxygen carrying capacity in their bloodstream then it's going to be hard to meet that oxygen saturation but replenishing the blood cells was not part of my interventions here so maybe in addition to administering oxygen I now need to add the administration of packed red blood cells to replenish the patient's blood supply and blood flow to help with the oxygenation. So in summary it is a fluid process that we always go through. We're constantly reassessing, we're constantly reevaluating, we're constantly looking at the goals and the interventions to get the patient to meet these goals to get them better and get them out of the hospital.
