KEEP CALM and PASS NCLEX with MARK KLIMEK Review 1. Acid-base balance/ventilators Rule of the B’s.. If the pH & the bicarb are both in the same direction = meta bolic If they are in different directions = respiratory pH = 7.35-7.45 acidosis/alkalosis HCO3 (bicarb) = 22-26 (2+2+2 = 6) CO2 = 45-35 ex: pH: 7.30 = ↓ bicarb: 20 = ↓ = metabolic acidosis ex: pH: 7.58 = ↑ bicarb: 32 = ↑ = metabolic alkalosis ex: pH: 7.22 = ↓ bicarb: 30 = ↑ = respiratory acidosis ex: You are providing care to a client with the followi ng blood gas results: pH 7.32, CO2 49, HCO3 29, PO2 80 & SaO2 90%. Based on the results, the cli ent is experiencing: ↓ = acidosis, ↑ = respiratory -opioid: CNS depressant.. know the symptoms (sedati on, respiratory depression, etc).. *principle: acid base signs/symptoms.. Nursing 4530 as the pH goes… so goes my patient!!! -when pH goes up; patient goes up .. (everything gets irritable!) -when pH goes down; patient goes down ! (systems in your body shut down) …except with potassium : when pH goes up; potassium goes down … when pH goes down; potassium goes up ! (up) alkalosis: irritibility, hyper-reflexia (3 & 4 ), tachypnea, tachycardia, borborygmi (increased bowel sounds), seizure, aspirate.. (down) acidosis: hypo-reflexia, bradycardia, lether gy (obtunded), paralytic ileus (decreased bowel sounds), coma, respiratory arrest (ambu-bag!! ) Kussmaul breathing is a deep and labored breathing pattern often associated with severe metabolic acidosis, particularly diabetic ketoacido sis (DKA) but also kidney failure… MAC Kussmaul !! M: metabolic AC: acidosis ex: pT has respiratory acidosis … (select all that apply).. +1 reflexes diarhhea adynamic ileus spasm urinary retention tachycardia 2nd degree mobits type 2 heart block hypokalemia SATA questions: *never only 1… never all of them* diarhhea will cause a metabolic acidosis.. but once you get acidodic, it will shut your bowels down = paralytic ileus …with scenarios.. always ask first “is it lung?” = respiratory …then ask if the pt is over-ventilating or under-ventilating ? over-ventilating = alkalosis under-ventilating = acidosis …it’s about the SaO2 !!! (pay attention!!) if it isn’t lung = metabolic .. if pt has prolonged gastric vomiting or suctioning … it’s always metabolic alkalosis … why? losing acid = becomes basic.. for everything else that is not lung - choose metabolic acidosis .. -if you don’t know the answer… always answer metabolic acidosis .. ventilators alarms.. high pressure alarm … triggered by increasure resistance to air flow.. (machine is pushing too hard to get air into the lungs).. respiratory alkalosis 3 obstructions: kink in tubing (get kink out), water condensing within the tube (empty tube), mucus secretions in the airway (turn, cough, deep breathe… then suction).. suctio n as needed!! *in that order*… low pressure alarm .. decreased resistance (too easy for the machine.. ) respiratory acidosis Low pressure alarms are triggered by decreased res istance to airflow & can be caused by disconnections of the main tubing or oxy gen sensor tubing… Tubing (reconnect it!) - oxygen sensor tube (reconnect it UNLESS tube is on t the floor - bag them & call Respiratory therapist if this happens) Respiratory alkalosis = ventilator setting may be too high . Respiratory acidosis = ventilator setting may be too low . What does “wean” mean? gradually decrease with the goal of getting off altogether ex: Doc says wean off vent in AM… 6am ABG’s show resp. acidosis … a) follow order b) call respiratory c) hold order.. call doc d) begin to decrease the settings MASLOW’s Priorities (HIGHest - LOWest) physiological safety comfort psychological (problems within the person) social (problems with other people) spiritual ex: Arrange from HIGHest - LOWest… denial, spiritual distress, pain in elbow, fall ris k, pathological family dynamics & electrolyte imbalance… = electrolyte imbalance (psyiological), fall risk ( safety), pain in elbow (comfort), denial (psychological), pathological family dynamics (soci al) & spiritual distress (spiritual) 2. alcoholism .. (or any abuse) #1 problem = denial *refusal to accept the reality of a problem* You treat denial by confronting it … pronouns ~ good: i… bad: you… positions ~ good: i’m having a difficult time reading this… bad: you wrote it wrong.. loss & grief: Denial Anger Bargining Depression Acceptance don’t confront it; support it.. ex: You have a pt that just hand a hand amputated & the y say, “I can’t wait to get back to playing the piano”… You say “Oh, how long have you played, etc ? - you NEVER say “You can’t because you only have 1 hand” abuse = confront loss = support #2 problem = dependency *when the abuser get the significant other to do so mething.. “Call my boss, i’m sick”* (abuser gets to keep abusing..) = co-dependency *calls the boss*… (positive self esteem) How to treat this?!? Set limits and enforce them … Learn to say NO! manipulation = when the abuser gets the significant other to do things for him or her… the nature of the act is dangerous or harmful how is it like dependency? the abuser is getting th e other person to do something no harm = dependent / co-dependent (wife buying alcohol for husband) dangerous/harmful = manipulated (kid buying alcohol for father) …depends on legal/illegal…………. Wernicke-Korsakoff Syndrome (WKS) is a neurological disorder. Wernicke's Encephalopathy and Korsakoff's Psychosis are the acute and chronic phases, respectively, of the same disease. WKS is caused by a deficiency in the B1 vitamin thiamine . Thiamine (B1) plays a role in metabolizing glucose to produce ene rgy for the brain. primary symptom of WKS = amnesia with confabulation (making up stories) *they believe the lie..* ex: You have a pt who believes he is Ronald Regan’s Nat ioal Security Officer… And they want to go to a cabinet meeting… :/ WHAT DO YOU DO?!? Redirec t!! (“well, why don’t you get a shower and then we’ll go watch CNN and see what the news i s in Washington D.C.”) WKS is… -It’s preventable & arrestable (stop it from gettin g worse) - Take vitamin B1 -Irreversible… *About 70%*
