ATI RN Dosage Calculation Exam 2024 with Correctly Worked Answers Question 1: A nurse is preparing to adm inister lactated Ringer's 250 mL IV to infuse over 15 min. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.). mL/hr. Explanation Step 1 is to calculate the total volume to be infused in mL/hr. This is done by dividing the total volume (250 mL) by the time in hours (15 min ÷ 60 min/hr). So, 250 mL ÷ (15 min ÷ 60 min/hr) = 1000 mL/hr. So, the correct answe r is 1000 mL/hr. Question 2: A nurse is preparing to administer cefazolin 1g intermittent IV bolus in 0.9% sodium chloride 250 mL over 30 min. The drop factor on the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV flow rate to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.). gtt/min. Explanation Step 1 is to calculate the total volume to be infused in mL/min. This is done by dividing the total volume (250 mL) by the time in minutes (30 min). So, 250 mL ÷ 30 min = 8.33 mL/min. Step 2 is to convert mL/min to gtt/min using the drop factor. So, (8.33 mL/min) × (10 gtt/mL) = 83.3 gtt/min. Round off to the nearest whole number, the correct answer is 83 gtt/min. Question 3: A nurse is preparing to reconstitute ampicillin for IM administration to a client who has urethritis. Which of the following information should the nurse interpret from the medication label? (Refer to the medication label below.). *This vial contains ampicillin sodium equivalent to 1 gram ampicillin. For IM use, add 3.5 ml diluent (read accompanying insert ). Resulting solution contains 250 mg ampicillin per mL. Use solution within 1 hour. Usage dosage: Adults -250 to 500 mg IM qóh. READ ACCOMPANYING INSERT. T tor. detailed indications, IM or IV dosage, and precautions. Store the dry powder at 20° to 25° C (68° to 77° F) (See USP]). NDC 1234 -1234 -10. Ampicillin for Injection, UŠP. 1 gram per vial. For IM or IV Use. End of label. A. Instill 5 mL of diluent to the vial for reconstitution. B. After reconstitution, the vial wi ll contain a total of 500 mg of medication. C. Administer the medication within 1 hr of reconstitution. D. This medication can only be administered IM. . Explanation Choice A rationale: The label states to add 3.5 mL of di luent for reconstitution, not 5 mL. So, choice A is incorrect. Choice B rationale: After reconstitution, the vial will contain 1 gram of medication, not 500 mg. So, choice B is incorrect. Choice C rationale: The label does state to use the solution within 1 hour of reconstitution. So, choice C is correct. Choice D rationale: The label states the medication can be used for IM or IV, not only IM. So, choice D is incorrect. Question 4: A nurse is preparing to administer ketorolac 30 mg IM to a client. Available is ketorolac injection 15 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.). mL. Explanation Step 1 is to determine the amount of medication needed. The order is for 30 mg and the available medication is 15 mg/mL. So, we calculate 30 mg ÷ 15 mg/mL = 2 mL. So the correct answer is 2 mL. Question 5: A nurse is preparing to administer morphine oral solution 30 mg PO for breakthrough pain to a client who has cancer. Available is morphine oral solution 20 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth.The benefits of buying summaries with Stuvia:
