Showing 10 questions, Sign in for moreA nurse is preparing to administer lactated Ringer's 250 mL IV to infuse over 30 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.)
Explanation
To calculate the mL/hr for the lactated Ringer's IV infusion over 30 minutes, you can use the following formula:
Rate (mL/hr)=Volume (mL)/Time (hr)
In this case:
Rate=250 mL/ 0.5 hr
Rate=500mL/hr
Therefore, the nurse should set the IV pump to deliver 500 mL/hr for the lactated Ringer's IV infusion over 1 hour.
A nurse is preparing to administer cefazolin 500 mg IM every 8 hr. Available is cefazolin 1 g vial. The package insert instructs adding sterile water 2.5 mL to yield cefazolin 330 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
To calculate the volume (mL) that the nurse should administer per dose, you can use the following formula:
Volume (mL) = Dose (mg)/Concentration (mg/mL)
In this case:
Volume = 500 mg/ 330 mg/mL
Volume≈1.5mL
Therefore, the nurse should administer approximately 1.5 mL per dose of cefazolin 500 mg IM.
A nurse is preparing to administer furosemide 30 mg IM to a client. Available is furosemide 10 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.)
Explanation
To calculate the volume (mL) that the nurse should administer, you can use the following formula:
Volume (mL) = Dose (mg)/Concentration (mg/mL)
In this case:
Volume = 30 mg/10 mg/mL
Volume=3mL
Therefore, the nurse should administer 3 mL of furosemide 30 mg IM.
A nurse is reviewing a client's new prescription for indomethacin 100 mg PO now, then 50 mg PO TID with food for pain relief. Which of the following actions should the nurse take?
A nurse is preparing to administer mycostatin 400,000 units PO every 6 hr. Available is mycostatin oral suspension 100,000 units/mL. How many ml should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
To calculate the volume (mL) that the nurse should administer per dose, you can use the following formula:
Volume (mL) = Dose (units)/Concentration (units/mL)
In this case:
Volume = 400,000 units/100,000 units/mL
Volume=4mL
Therefore, the nurse should administer 4 mL of Mycostatin oral suspension per dose.
A nurse is preparing to administer tobramycin 3 mg/kg/day IM in three divided doses to a client who weighs 85 kg. Available is tobramycin 40 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
To calculate the total daily dose of tobramycin, we use the formula:
Total Daily Dose (mg) = Dose (mg/kg/day) × Weight (kg)
Total Daily Dose (mg)=Dose (mg/kg/day)×Weight (kg)
In this case:
Total Daily Dose=3 mg/kg/day × 85 kg
Total Daily Dose=255mg/day
Since the total daily dose is divided into three doses, the nurse should administer:
Dose per Administration =Total Daily Dose/Number of Doses per Day
Dose per Administration = 255 mg/3
Dose per Administration≈85mg
Now, to calculate the volume (mL) to administer, we use the concentration of the available tobramycin solution:
Volume (mL)=Dose per Administration (mg)/Concentration (mg/mL)
In this case:
Volume=85mg/40mg/mL
Volume≈2.1mL
Therefore, the nurse should administer approximately 2.1 mL of tobramycin per dose, rounded to the nearest tenth.
A nurse is assisting in the care of a client who is to receive 0.9% sodium chloride 1,800 mL IV over 6 hr. The nurse should ensure the IV pump is set 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.)
Explanation
To calculate the infusion rate (mL/hr), you can use the following formula:
Infusion Rate (mL/hr)=Total Volume (mL)/Total Time (hr)
In this case:
Infusion Rate=1,800 mL/6 hr
Infusion Rate=300mL/hr
Therefore, the nurse should ensure the IV pump is set to deliver 300 mL/hr for the 0.9% sodium chloride infusion over 6 hours, rounded to the nearest whole number.
A nurse is preparing to administer methotrexate 7.5 mg subcutaneous for a client who has rheumatoid arthritis. Available is methotrexate 15 mg/0.4 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
To give a client with rheumatoid arthritis a subcutaneous dose of methotrexate 7.5 mg, the nurse needs to calculate the correct volume of the drug solution. T
he drug solution has a concentration of 15 mg/0.4 mL, which means that 0.4 mL of the solution contains 15 mg of methotrexate. To find the volume of the solution that contains 7.5 mg of methotrexate, the nurse can use a proportion:
15 mg/0.4 mL = 7.5 mg/x mL
Cross-multiplying and solving for x gives:
x = (0.4 mL x 7.5 mg) / 15 mg
x = 0.2 mL
Therefore, the nurse should administer 0.2 mL of the drug solution to deliver 7.5 mg of methotrexate subcutaneously.
A nurse is preparing to administer ketorolac 30 mg IM for a loading dose. 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
Explanation
To calculate the volume (mL) that the nurse should administer, you can use the following formula:
Volume (mL)=Dose (mg)/Concentration (mg/mL)
In this case:
Volume =30 mg/15mg/mL
Volume=2mL
Therefore, the nurse should administer 2 mL of ketorolac for the 30 mg loading dose, rounded to the nearest whole number.
A nurse is preparing to administer calcitonin 8 units/kg IM to a client who weighs 165 lb. Available is 200 units/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.)
Explanation
To calculate the volume (mL) that the nurse should administer, we can follow these steps:
Convert the weight from pounds to kilograms.
1 lb = 0.453592 kg
165 lb×0.453592 kg/lb≈74.843 kg
Calculate the total dose using the weight and prescribed dose:
Total Dose (units)=Dose per kg×Weight (kg)
Total Dose=8 units/kg×74.843 kg≈598.744 units
Determine the volume using the concentration of the available solution:
Volume (mL)=Total Dose (units)/Concentration (units/mL)
Volume =598.744 units/200 units/mL ≈ 2.994 mL
Therefore, the nurse should administer approximately 3 mL of calcitonin for the 8 units/kg IM dose, rounded to the nearest whole number.
