Coagulations! Safety & Complications If the patient faints, you should do all of the following, except:  Remove the needle first, even if it means you can’t break their fall  Stay with the patient for 10 minutes and don’t let them drive for at least 15  Loosen their collar, and have them put their head between their knees  Note in the chart that they fainted Which is not a reason for failure to draw blood?  You passed through the vein to the other side  The vein rolled to the side because your insertion was too slow  Defective tube  You took up too much skin slack Which is/are not indicated if you miss the vein (select all correct answers)?  Try again (up to 5 times in one arm is okay)  Palpate with gloved finger before you assume the tube is defective

If you cause a bruise (hematoma), all except which of the following are recommended?  Heat  Apply direct pressure  Elevate the area  Keep the arm straight, not bent  Suggest no heavy lifting MM, a 44-yo female is in hospital and you have been given permission to do some IV therapy using an existing IV port. When you arrive, MM’s injection site is red with streaking. The site is tender to the touch, and the vein feels hard. She has flushed cheeks, and is feeling warm. You suspect:  Thrombosis and recommend a heparin flush  Phlebitis and recommend removing the needle and applying a cold compress  Cellulitis and recommend IV antibiotics  Thrombophlebitis and prepare for a law suit Q: What does a weight-conscious vampire drink? A: Blood Light. Which of the following is false about speed shock?  Likely caused by too fast a push  Can be caused by a magnesium infusion  Remove the needle  S/S include flush, perspiration, vertigo, decreased pulse rate, arrhythmia, coma Which of the following Crash Cart matches is incorrect?  Oxygen for shock  Unrefrigerated calcium gluconate for Mg overdose  Amyl nitrate for syncope  Benadryl in Epipen for anaphylactic shock You’ve been doing a Mg push, and your patient tells you they’re starting to feel funny. Which of the following adverse reactions could not be caused by Mg IV (pick 2):  Mental confusion, fatigue, perspiration, irritability, palpitations = hypoglycemia  Tingling in the extremities, shakes, convulsions = hypocalcemia  Tingling in the extremities, shakes, convulsions = hypoparathyroid  Mental confusion, fatigue, perspiration, irritability, palpitations = hypocalcemia PT, a 32 yo male is coming in for his first IV treatment with you. After some time, he begins to describe a throbbing in his chest and says that he can feel his heart beating. You take his pulse and note that it is 105 bpm. His breathing is laboured. What is happening and what should you do?

   

Allergic response – administer Benadryl Hypoglycemia – administer D5W Hypocalcemia – administer calcium gluconate Hypercalcemia – administer Mg chloride

Q: Why are vampire families so close? A: Because blood is thicker than water! Lab results can be altered by all except one of the following:  Fasting (glucose down, TGs down, electrolytes down)  Exercise (platelet factors up, creatinine up, AST up, electrolytes up)  Stress (WBC up, albumin up, glucose up)  Age (cholesterol up, DHEA and estrogen down)  Posture (cholesterol up, TG up, calcium altered)  Pregnancy (RBC down, hCG up, albumin down) Which of the following drug or supplements does not cause the listed alteration to lab results?  OCP depletes B vitamins  Vitamin C interacts with the fecal occult test, and can affect glucose readings  Methotrexate lowers folic acid levels  Vitamin D increases ionized calcium values Top Ten Things To Do While Giving Blood (by Tina Mancuso and Paul Coen) 10. Watch the bag fill. 9. Hyperventilate. 8. Pull the tube out of the bag and drink from it. 7. Race to see who fills their bag first (requires two or more people). 6. Puncture the bag near the top and see whether they pull the needle out of your arm before the blood squirts out. 5. While they're not looking, substitute a bag of orange liquid and complain they gave you too much Tang. 4. Insist that you want to give 2 pints. 3. Faint. 2. Tell them you saw the bag twitch. 1. Yell, "Hey, you used that needle on the last guy!"

IV Therapy History + Minerals Which is the incorrect “history of IV therapy” match?  Christopher Wren invented the 1st hypodermic needle – a bird feather!  James Blundell gave the 1st blood transfusion after a post-partum hemorrhage

Which is not a major safety concern when doing injections  Introducing air (especially IM) You are treating a patient with ulcerative colitis and want to give Vitamin C intravenously.

Ozone 32yr male patient came into your office for ozone therapy.....you proceed to insufflate ozone into his lungs and are halfway into the treatment when he starts to experience respiratory distress....This is because: A. he is choking on his chewing gum B. you should never put ozone into the lungs C. you are administering more than 3-5mcg/ml D. he is a smoker and the ozone is increasing the oxygen saturation Ozone and hydrogen peroxide (H2O2) are CI in porphorias, sickle cell anemia, thalessemia because (PS - to make this question harder, could give S/S and/or labs for eg thalessemia  Hb aren’t as good at carrying O2  body makes more RBC; diagnostic = electrophoresis; this pt looks iron def’t (low ferritin in alpha, ?higher in beta)), but giving Fe longterm doesn’t solve the problem): A. they increase the activity of the RBC B. the RBC are already compromised in these diseases and ozone and H2O2 treatment will cause further cell damage C. ozone and H2O2 are antioxidants D. ozone and H2O2 need to be given with Vitamin C Chelation Which of these lab values should be monitored, if warranted, in a patient before receiving EDTA chelation therapy? (note: a) could also be correct because depending on their initial iron level and overall metal status a) Ferritin

b) Creatinine c) Prothrombin Time d) Glucose Which of these substances does EDTA have the least affinity for? (Al is hard to chelate and most things that can do it are very toxic) a) Pb b) Hg c) Cd d) Al During the course of treatment a patient exhibits nervousness, sweating, weakness and intense hunger. Which course of action would be best to take? (If they are hypoglycaemic you want to have the needle still in so you can admin glu; a) is correct if pt goes into shock) a) Call 911 and begin emergency protocols b) Provide the patient with some juice/crackers c) Alter dose of EDTA given (Saunders says: not really, just feed them beforehand, because Mg will be released when you pick up Ca) d) Both B & C e) All of the above What, in IV, could push someone into hypoglycaemia?  Mg (^ATP production & breakdown catecholamines --> feel hungry) Calcium-EDTA is best for chelating out which substance? a) Pb b) Ca c) Hg d) Al After a course of treatment with DMSA a 53 year old female patient experiences fatigue and dark red urine. Lab results indicate Hb = 9g/dL (low), increased reticulocyte count (compensation), indirect bilirubin = 3mg/dL and LDH (bone, LV, HT) levels above normal levels. Which of these conditions does the patient most likely have? a) Von Willebrand’s disease (PT diagnostic g/t def’y Factor VIII?) b) G6P-dehyrogenase deficiency (DMSA can cz haemolytic anemia m/b d/t Cu Ez pathways) c) Iron deficiency anemia (MCV, ferritin… important in diagnostis; we may not have enough answer to really rule this out – thanks JB!) d) Hemophilia (mostly male, plus would have caught it by now)
