Yоu аre treаting а 148-lb man whо is in status epilepticus.  Yоu are ordered to start an IV of D5W to be run at a KVO (30 ml/hr) rate.  You select a 500 ml bag of D5W and a mini-drip solution set. How many gtt/min do you run the IV? [A1] gtt/min   The base physician requests you to administer 5 mg of diazepam slow IV push.  Your pre-filled syringe of diazepam comes packaged as “10 mg/2ml.   What is the concentration of diazepam? [A2] mg/ml   How many ml of diazepam do you push? [A3] ml

Situаtiоn 13: Yоu аrrive аt a private hоme to find a 7-year –old child in cardiac arrest due to a near-drowning episode.  The police are on scene and doing beautiful CPR on the child.  The mother tells you the child weighs 53 lb.  While the police officer continues compressing the chest, the child is intubated and electrodes are placed.  The monitor shows asystole.  You start an IV of NS, using a 500-ml bag and a mini-drip solution set.  You run the IV at a rate of 30 cc per hour.  The first drug you are to give is epinephrine 1:10,000 IV push at a dosage of 0.01 mg/kg.  Your pre-filled syringe of epinephrine is labeled “1 mg/10 ml.” How many gtt/min do you run the IV? [A1] gtt/min   What is the patient’s weight? [A2] kg   What is the concentration of the drug? [A3] mg/ml   How many ml of epinephrine do you administer? [A4] ml   There is no change in the patient’s condition.  You are ordered at this time to administer atropine IV push at a dose of 0.02 mg/kg.  Your pre-filled syringe of atropine is labeled “2 mg/10 ml.” What is the concentration of the drug? [A5] mg/ml   How many ml of atropine do you administer? [A6] ml   The patient’s condition does not change.  Due to the nature of the episode, the physician orders sodium bicarbonate be given IV push at a dose of 1 mEq/kg.  Your pre-filled syringe of sodium bicarbonate is labeled “50 mEq/50 ml.” What is the concentration of the drug? [A7] mEq/ml   How many ml of sodium bicarbonate do you administer? [A8] ml   There is still no change in the patient’s condition, but 5 minutes have passed.  The physician wants the epinephrine repeated.  1 minute after the epinephrine is given the ECG shows a bradycardia rhythm at a rate of 32/min.  You detect a faint femoral pulse but you are unable to obtain a BP.  The patient’s capillary refill is non-existent.  The physician requests you administer atropine IV push at a dose of 0.5 mg.  Your pre-filled syringe of atropine is labeled “1 mg/10 ml.” What is the concentration of the drug? [A9] mg/ml   How many ml of atropine do you administer? [A10] ml   You give the atropine, but there is no increase in the heart rate.  The physician requests you set up an epinephrine drip to start at 0.2 mcg/kg/min.  You mix 1 mg of epi into 250 ml of D5W.  You attach a mini-drip solution set.  What is the concentration of the epi mixture? [A11] mcg/ml   How many gtt/min of do you run the epi drip? [A12] gtt/min   The patient’s heart rate increases to 58/min, but you are still unable to palpate a BP.  The patient’s capillary refill is approximately 4 seconds.  The physician at this time requests you increase the epi drip to 0.3 mcg/kg/min. How many gtt/min of do you run the epi drip? [A13] gtt/min

Situаtiоn 8: Yоu аre treаting a 162.8 lb male whо is in cardiac arrest.  The patient is in ventricular fibrillation and CPR is started.  After you deliver three shocks without success, you place the electrodes.  The patient remains in V fib, and CPR continues.  You have assured the patient’s airway by endotrachael intubation and you initiate an IV using a mini-drip solution set and a 500-ml bag of D5W.  The IV is to run to infuse 100 cc in one hour. What is the patient’s weight? [A1] kg   How many gtt/min do you run the IV? [A2] gtt/min   You follow standing order protocols, and administer epinephrine 1:10,000, 0.5-mg IV push.  Your pre-filled syringe of epinephrine comes packaged as “1 mg/10 ml.” What is the concentration of the epinephrine? [A3] mg/ml   How much epinephrine do you push? [A4] ml   After shocking again, without rhythm change, you are to administer lidocaine, 1 mg/kg IV push.  Your pre-filled syringe of lidocaine comes packaged as “100 mg/10 ml.” What is the concentration of the lidocaine? [A5] mg/ml   How much lidocaine do you push? [A6] ml   You shock again, but again there is no rhythm change. You are to administer lidocaine, 0.5-mg/kg IV push. How much lidocaine do you push? [A7] ml   You shock again, but again there is no rhythm change.  The next drug you are to give is bretylium tosylate, 5 mg/kg, IV push.  Your pre-filled syringe of bretylium comes packaged as “500 mg/10 ml.” What is the concentration of the bretylium? [A8] mg/ml   How much bretylium do you push? [A9] ml   Your standing orders allow you, at this point, to administer sodium bicarbonate IV push at a dosage of 1 mEq/kg.  Your pre-filled syringe comes packaged as “50 mEq/50 ml.” What is the concentration of the sodium bicarbonate? [A10] mEq/ml   How much sodium bicarbonate do you push? [A11] ml   You defibrillate again, but there is no rhythm change.  Your next action is to give bretylium IV push at a dosage of 10 mg/kg. Your pre-filled syringe of bretylium comes packaged as “500 mg/10 ml.” What is the concentration of the bretylium? [A12] mg/ml   How much bretylium do you push? [A13] ml   You deliver the seventh shock, and the monitor rhythm changes to third degree heart block.  You find a faint carotid pulse at 40/min.  Your protocols for this situation call for the IV push administration of atropine, 0.5 mg.  Your pre-filled syringe of atropine comes packaged as “1 mg/10 ml.” What is the concentration of the atropine? [A14] mg/ml   How much atropine do you push? [A15] ml   There is a slight increase in HR to 44/min.  You repeat the atropine at 0.5 mg, but see no increase from this dose this time.  You decide to give atropine, 1.0 mg, by IV push. Your pre-filled syringe of atropine comes packaged as “1 mg/10 ml.” What is the concentration of the atropine? [A16] mg/ml   How much atropine do you push? [A17] ml   After having administered the 1-mg of atropine, your patients HR is 48/min, and he is still in third degree AV block.  You are to give isoproterenol IV drip at 2 mcg/min.  You mix 1 mg of isoproterenol into a 250-ml bag of D5W, and hang the drip using a mini-drip solution set. What is the concentration of the isoproterenol solution? [A18] mcg/ml   How many gtt/min do you run the isoproterenol drip? [A19] gtt/min   The isoproterenol at 2 mcg/min does not increase the heart rate, and you decide to increase the isoproterenol drip to 4 mcg/min. How many gtt/min do you run the isoproterenol drip? [A20] gtt/min   The isoproterenol at 4 mcg/min increases the heart rate slightly, and you decide to increase the isoproterenol drip to 6 mcg/min. How many gtt/min do you run the isoproterenol drip? [A21] gtt/min   Your patient’s heart rate increases to 56/min, but his blood pressure is still too low.  Your base physician requests you increase the isoproterenol drip to 7 mcg/min. How many gtt/min do you run the isoproterenol drip? [A22] gtt/min   Your patient’s HR at 7 mcg/min is 60, and his BP is 90/60.  The patient remains stable the rest of the trip.
