Because your patient is conscious, you are ordered to start an IV of D5W at a rate of 30cc/hr and then sedate him with diazepam prior to cardioversion. You start the IV of D5W using a mini-drip solution set. Your order for diazepam is for an IV push dose of 5 mg. Your pre-filled syringe of diazepam is labeled “10 mg/2 ml.” How many seconds are between each drop? [A1] gtt/min What is the concentration of the drug? [A2] mg/ml How many ml of diazepam do you administer? [A3] ml Once the diazepam is on board, your patient appears sufficiently sedated. You proceed with cardioversion at 50 joules. The rhythm changes to NSR. The physician requests you administer lidocaine IV push at 1 mg/kg. Your pre-filled syringe of lidocaine is labeled “100 mg/5 ml.” What is the patient’s weight? [A4] kg What is the concentration of the drug? [A5] mg/ml How many ml of lidocaine do you administer? [A6] ml 2 minutes after the lidocaine is on board, the monitor shows ventricular tachycardia again. Your patient still has a weak pulse. You deliver a second cardioversion at 50 joules and the rhythm changes to NSR. The physician advises giving procainamide IV drip at a rate of 20 mg/min until 1 gm has been given or the BP decreases or the QRS widens by 50% of its original width. Your pre-filled syringe of procainamide is labeled “1 gm/10 ml, and you mix it into a 100 ml bag of D5W and use a mini-drip solution set. What is the concentration of the procainamide syringe? [A7] mg/ml What is the concentration of the procainamide mixture? [A8] mg/ml How many gtt/min do you run the IV? [A9] gtt/min After 2 minutes of administration, the patient’s BP begins to fall. The physician at this time requests no further administration of procainamide. # minutes later, the monitor again shows V-tach.

Your ampule of bretylium is labeled “500 mg/10 ml.” What is the concentration of the bretylium tosylate? [A10] mg/ml How many ml of the bretylium tosylate do you add to the 50-ml of D5W? [A11] ml What is the concentration of the bretylium tosylate mixture? [A12] mg/ml How many ml/min do you give of the bretylium tosylate mixture? [A13] ml/min The bretylium tosylate injection converts the patient back into NSR. The physician requests you to hang a bretylium tosylate IV drip at a rate of 1 mg/min. You mix 1gm of bretylium tosylate into a 250-ml bag of D5W. You use a mini-drip solution set. What is the concentration of the bretylium tosylate mixture? [A14] mg/ml How many gtt/min do you run the bretylium tosylate drip? [A15] ml/min
Situаtiоn 9: Yоu hаve а 125-lb patient whо is suffering an acute asthma attack. You are to start an IV of D5W at a rate to infuse 50cc in 10 minutes.
