N601 Saunders Fundamentals Medications & IV Calculations Week 7 | Questions & Answers both graded already, (2021) -1) The nurse is completing a time tape for a 1000-mL intravenous (IV) bag that is sch... eduled to infuse over 8 hours. The nurse has just placed the 1100 marking at the 500-mL level. The nurse would place the mark for 1200 at which numerical level (mL) on the time tape? Fill in the blank. mL Correct answer: 375 mL Rationale: If the IV is scheduled to run over 8 hours, the hourly rate is 125 mL/hour. Using 500 mL as the reference point, the next hourly marking would be at 375 mL, which is 125 mL less than 500.

The drop factor is 15 drops (gtt)/1 mL. The nurse prepares to set the flow rate at how many drops per minute? Fill in the blank. Record your answer to the nearest whole number. drops per minute Correct answer: 21 drops per minute Rationale: Use the intravenous (IV) flow rate formula. Formula: Total volume × Drop factor –––––––––––––––––––––––––– = gtt/min Time in minutes 1000 mL × 15 gtt 15,000 –––––––––––––––– = –––––– = 20.8 gtt/min 720 minutes 720 = 21 gtt/min Cognitive Ability: Applying Client Needs: Physiological Integrity Integrated Process: Nursing Process: Implementation Content Area: Fundamentals of Care: Medication/IV Calculations Strategy(ies): Subject Priority Concepts: Clinical Judgment, Safety 3) A health care provider's prescription reads to administer an intravenous (IV) dose of 400,000 units of penicillin G benzathine. The label on the 10-mL ampule sent from the pharmacy reads penicillin G benzathine, 300,000 units/mL. The nurse prepares how much medication to administer the correct dose? Fill in the blank. Record your answer using 1 decimal place. mL Correct answer: 1.3 mL Rationale: Use the medication dose formula. Formula: Desired × mL –––––––––––– = mL/dose Available 400,000 units × 1 mL –––––––––––––––––––– = mL/dose 300,000 units 400,000 units ––––––––––––– = 1.33 = 1.3 mL 300,000 units Cognitive Ability: Applying Client Needs: Physiological Integrity Integrated Process: Nursing Process: Implementation Content Area: Fundamentals of Care: Medication/IV Calculations Strategy(ies): Subject Priority Concepts: Clinical Judgment, Safety 4) A health care provider's prescription reads potassium chloride 30 mEq to be added to 1000 mL normal saline (NS) and to be administered over a 10-hour period. The label on the medication bottle reads 40 mEq/20 mL. The nurse prepares how many milliliters of potassium chloride to administer the correct dose of medication? Fill in the blank. mL Correct answer: 15 mL Rationale: In most facilities, potassium chloride is premixed in the intravenous solution and the nurse will need to verify the correct dose before administration. In some cases the nurse will need to add the potassium chloride and will use the medication calculation formula to determine the mL to be added. Formula: Desired × mL –––––––––––– = mL/dose Available 30 mEq × 20 mL –––––––––––––– = 15 mL 40 mEq Cognitive Ability: Applying Client Needs: Physiological Integrity Integrated Process: Nursing Process: Implementation Content Area: Fundamentals of Care: Medication/IV Calculations Strategy(ies): Subject Priority Concepts: Clinical Judgment, Safety 5) A health care provider's prescription reads clindamycin phosphate 0.3 g in 50 mL normal saline (NS) to be administered intravenously over 30 minutes. The medication label reads clindamycin phosphate 900 mg in 6 mL. The nurse prepares how many milliliters of the medication to administer the correct dose? Fill in the blank. mL Correct answer: 2 mL Rationale: You must convert 0.3 g to milligrams. In the metric system, to convert larger to smaller, multiply by 1000 or move the decimal 3 places to the right. Therefore, 0.3 g = 300 mg. Following conversion from grams to milligrams, use the formula to calculate the correct dose. Formula: Desired × mL –––––––––––– = mL/dose Available 300 mg × 6 mL ––––––––––––– 900 mg 300 mg × 6 mL = –––––––––––––– = 2 mL 900 mg Cognitive Ability: Applying Client Needs: Physiological Integrity Integrated Process: Nursing Process: Implementation Content Area: Fundamentals of Care: Medication/IV Calculations Strategy(ies): Subject Priority Concepts: Clinical Judgment, Safety 6) A health care provider's prescription reads phenytoin 0.2 g orally twice daily. The medication label states that each capsule is 100 mg. The nurse prepares how many capsule(s) to administer 1 dose? Fill in the blank. capsules Correct answer: 2 capsules Rationale: You must convert 0.2 g to milligrams. In the metric system, to convert larger to smaller, multiply by 1000 or move the decimal point 3 places to the right. Therefore, 0.2 g equals 200 mg. After conversion from grams to milligrams, use the formula to calculate the correct dose. Formula: Desired × Capsule(s) –––––––––––––––––––– = Capsule(s)/dose Available 200 mg × 1 Capsule –––––––––––––––––– = 2 Capsules 100 mg Cognitive Ability: Applying Client Needs: Physiological Integrity Integrated Process: Nursing Process: Implementation Content Area: Fundamentals of Care: Medication/IV Calculations Strategy(ies): Subject Priority Concepts: Clinical Judgment, Safety 7) A health care provider prescribes 1000 mL of normal saline 0.9% to infuse over 8 hours. The drop factor is 15 drops (gtt)/1 mL. The nurse sets the flow rate at how many drops per minute? Fill in the blank. Record your answer to the nearest whole number. drops per minute Correct answer: 31 drops per minute Rationale: Use the intravenous (IV) flow rate formula. Formula: Total volume × Drop factor –––––––––––––––––––––––––– = gtt/min Time in minutes 1000 mL × 15 gtt 15,000 –––––––––––––––– = –––––– = 31.2 gtt/min 480 minutes 480 = 31 gtt/min Cognitive Ability: Applying Client Needs: Physiological Integrity Integrated Process: Nursing Process: Implementation Content Area: Fundamentals of Care: Medication/IV Calculations Strategy(ies): Subject Priority Concepts: Clinical Judgment, Safety 8) A health care provider prescribes heparin sodium, 1300 units/hour by continuous intravenous (IV) infusion. The pharmacy prepares the medication and delivers an IV bag labeled heparin sodium 20,000 units/250 mL D5W. An infusion pump must be used to administer the medication. The nurse sets the infusion pump at how many milliliters per hour to deliver 1300 units/hour? Fill in the blank. Record your answer to the nearest whole number. mL per hour Correct answer: 16 mL per hour A health care provider prescribes heparin sodium, 1300 units/hour by continuous intravenous (IV) infusion. The pharmacy prepares the medication and delivers an IV bag labeled heparin sodium 20,000 units/250 mL D5W. An infusion pump must be used to administer the medication. The nurse sets the infusion pump at how many milliliters per hour to deliver 1300 units/hour? Fill in the blank. Record your answer to the nearest whole number. Rationale: Calculation of this problem can be done using a 2-step process. First, you need to determine the amount of heparin sodium in 1 mL. The next step is to determine the infusion rate, or milliliters per hour. Step 1: Known amount of medication –––––––––––––––––––––––––– = Medication/mL Total volume of diluent 20,000 units –––––––––––– = 80 units/mL 250 mL Step 2: Dose per hour desired ––––––––––––––––––––– = mL/hr Concentration per mL 1300 units ––––––––––– = 16.25 mL/hr [Show More]
