NURSING MISC DOSAGE & CALULATIONS CHAPTER 6-7 Rounding Rules True or False During multi-step calculations, such as temperature conversions, rounding should take place only at the end of the calculation. True or False Temperature conversions should be rounded to the tenths place. True or False When calculating a weight in pounds or kilograms, round to the tenths place. Conversions Fill in the highlighted area 42 inches = ft x ft = ft x _42 in_ (what information belongs here) in 1 1.5 tsp = mL x mL = mL x 1.5 tsp tsp 1 (what abbreviation belongs here) 75 lb = kg x kg = kg x 75 lb (what abbreviation belongs in the ? spot) lb 1 Temperature Conversions Fill in the highlighted area 99.6 F = 37.6 C 99.6 – 32 = 67.6 67.6 divide by 1.8 = 37.55 = 37.6 41.2 C = 106.2 F 41.2 x 1.8 = 74.16 74.16 + 32 = 106.16 = 106.2 Convert 2 ¼ to a decimal. 2.25 (2x4=8+1=9 then divide 9 by 4) CHAPTER 8-13 What are the six rights of medication administration?

(p. 188) True or False: The form is how a drug is supplied. Ex. Capsules, liquids, or tablets. (p. 188) True or False: Enteric coated, extended release, and sustained release pills may be split or crushed. (p. 198) Round to the 10ths place (p. 201) 3.87mL = 3.9mL 2.45mL = 2.5mL 3.32mL = 3.3mL 5.05mL = 5.1mL True or False: An intradermal injection is administered beneath the skin, in fat. o An intradermal injection is administered within the skin. o A subcutaneous injection is administered beneath the skin, in fat. True or False: An intramuscular injection can be administered/inserted at either a 45 degree or 90 degree angle. o Intramuscular injections are administered/inserted at a 90 degree angle. o Subcutaneous injections can be administered/inserted at either a 45 degree or 90 degree angle. True or False: It is safe to injection your patient with a filter needle following withdrawing medication from an ampule. On a 50-unit insulin syringe, each calibration equals how many units? One unit o On a 30-unit insulin syringe, each calibration also equal one unit. On a 100-unit insulin syringe, each calibration equals how many units? Two units Which insulin cannot be mixed in the same syringe with other types of insulin? Lantus Rounding Rules The hundredths place is how many spaces to the right of the decimal? Two spaces Oral liquids round to which place, the tenths or hundredths? Tenths When dealing with greater than 1mL, round to the tenths place. When dealing with less than 1mL, round to the hundredths place. Practice Problems Hydrochlorothiazide is available in 25mg tablets. Give Hydrochlorothiazide 12.5mg by mouth every twelve hours. Fill in the blanks/set up the problem. 12.5mg x 1 tab 25mg How many tablets will be administered per dose? 0.5 tab/dose Lortab Elixir 5mg by mouth every 4 hours as need for pain is ordered. The medication is available in 7.5mg/15mL. How many mLs will the nurse administer? 5mg x 15mL 7.5mg 1 How many mL will be administered per dose? 9.99 = 10mL/dose CHAPTER 14-15 What type of diluent is needed? water How much diluent is needed? 67mL What is the dosage strength of the medication? 125mg/5mL If the nurse administers 12.5mL per dose, how many doses can be administered from the bottle? 6 doses o There are two pieces of information you need to solve this problem · how many mL are in the bottle (75mL when reconstituted) · how many mL will be administered with each dose (12.5mL) 75mL = 6 doses 12.5mL What does the abbreviation IVPB mean? IV piggyback A macrodrip set delivers 10, 15, and 20 drops per milliliter. (p. 436) A microdrip set delivers 60 drops per milliliter. (p. 436) The drop factor is the number of drops contained in one milliliter. (p.436) Order: Normal Saline 500mL to infuse over 8 hours. The nurse will program the IV pump for how many milliliters per hour? o There are two pieces of information you need to set up and solve this problem. · 500mL · 8 hours 500mL = 62.5 =63mL/h 8H Order: D5W 100mL to infuse over 12 hours. The tubing drop factor is 30gtt/mL. How many drops per minute will be given? o There are three pieces of information you need to set up and solve this problem · 100mL · minutes but you have hours – 12 hour x 60 minutes = 720 minutes · 30gtt/mL tubing drop factor 100mL x 30gtt/mL = 4.16 = 4gtt/min 720min Order: Vancomycin 250mL to infuse over 80 minutes. The nurse will program the IV pump to how many milliliters per hour? o There are two pieces of information you need to set up and solve this problem · 250mL · hours but you have minutes 250mL x 60min = 187.5 = 188mL/hr 80min 1hR Order: Morphine sulfate 15mg/hr. Available is a bag with 100mg of morphine sulfate in 200mL of D5W. The nurse will program the IV pump for how many milliliters per hour? o There are two sets of information you need to set up and solve this problem · 15mg per hr · 100mg in 200mL x mL = 200mL x 15mg = 30mL/hr 100mg 1hr Rounding Rules Drops/min (gtt/min) round to which space? The nearest whole number, no decimals Milliliters/hour (mL/hr) round to which space? The nearest whole number, no decimals
