.
The patient medication order reads “Cyanocobalamin 500 mcg IM now.” You find a vial of cyanocobalamin that is 1,000 mcg/mL and give the patient a 1 mL injection in the deltoid muscle of her left arm. When you get ready to chart the medication, you realize you should have given only 0.5 mL of the medication. What should you do now?

The tube feeding is administered at 75 ml/hour for 11 hours (0700 – 1800) and then turned off for one hour because the residual is greater than 200 ml. 11 hours x 75 ml/hr = 825 ml. Three doses of 20 ml of medication are administered, with 10 ml of water used to flush the GT before and after each dose. 20 ml x 3 doses = 60 ml; 10 ml (flush) x 2 x 3 doses = 60 ml; so 825 ml + 60 ml + 60 ml = 945 ml. 250 ml of residual is removed and not replaced. 945 ml – 250 ml = 695 ml total fluid balance (Intake – output).

8 grams = 8,000 mg prescribed dose. Using the formula, D/H x Q, 8,000 mg / 200 mg x 1 ml = 40 ml of the 20% solution. Dilute the 40 ml to a 1:4 concentration for administration using ratio and proportion, 1 : 4 solution :: 40 ml : X X= 160 ml total volume to administer. Subtract total volume of 160 ml – 40 ml of 20% concentration = 120 ml diluent is added to obtain a 1:4 concentration.
A child who weighs 55 pounds receives a prescription for atovaquone with proguanil (Malarone Pediatric) 125 mg/50 mg PO daily. A drug reference states that children 11 to 20 kg should receive 1 pediatric tablet daily; 21 to 30 kg should receive 2 pediatric tablets daily; 31 to 40 kg should receive 3 pediatric tablets daily; and greater than 40 kg should receive 1 adult tablet daily with food. The drug is available as atovaquone 62.5 mg/proguanil 25 mg pediatric tablets. How many tablets should the nurse administer?
A child who is scheduled for a kidney transplant receives a prescription for basiliximab (Simulect) 20 mg IV 2 hours prior to surgery. The medication is available in a 20 mg vial that is reconstituted by adding 5 ml sterile water for injection, and administered in a 50 ml bag of normal saline over 30 minutes. The nurse should program the infusion pump to deliver how many ml/hour? (Enter the numeric value only.)
A client with a gastrostomy tube (GT) receives a prescription for Osmolite® 1/2 strength enteral formula at 80 ml/hour. To prepare a 4 hour solution, the nurse should dilute the full-strength formula with how many ml of water? (.)
Determine the total volume needed at 80 ml/hour x 4 hours = 320 ml. Use the formula, Desired strength/strength on Hand x Volume = 50/100 x 320 = 160 ml of Osmolite® enteral formula, which must be diluted to half strength. Or use ratio and proportion, Desired strength (1/2 = 1 part : 2 parts) :: Volume of full strength : Total Desire volume 1 : 2 :: X : 320 ml 2X = 320, and X = 160 ml of Osmolite® enteral formula, full strength 320 ml total volume – 160 ml of full-strength formula = 160 ml of water to create 1/2 strength or 50% concentration.
