Showing 10 questions, Sign in for moreA nurse is assisting in the care of a client who is receiving gentamicin 60 mg via intermittent IV bolus. Available is gentamicin 60 mg/100 mL to infuse over 75 min. 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 for gentamicin, the nurse should use the following formula:
Infusion rate (mL/hr) = Volume (mL) / Time (hr)
Plugging in the given values, we get:
Infusion rate (mL/hr) = 100 mL / (75 min / 60 min/hr)
Simplifying, we get:
Infusion rate (mL/hr) = 100 mL / 1.25 hr
Dividing, we get:
Infusion rate (mL/hr) = 80 mL/hr
Therefore, the nurse should ensure the IV pump is set to deliver 80 mL/hr of gentamicin.

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 dose of calcitonin for a client who weighs 165 lb, the nurse needs to convert the weight to kilograms first.
One kilogram is equal to 2.2 lb, so the client's weight in kilograms is 165 / 2.2 = 75 kg.
The prescribed dose is 8 units/kg, so the total dose is 8 x 75 = 600 units.
The available concentration is 200 units/mL, so the volume to administer is 600 / 200 = 3 mL.
The nurse should administer 3 mL of calcitonin IM to the client.
A nurse is preparing to administer morphine 7.5 mg subcutaneous. Available is morphine injection 10 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
To calculate the dosage of morphine, the nurse needs to use the formula D/H x V, where D is the desired dose, H is the dose on hand, and V is the volume on hand. In this case, D is 7.5 mg, H is 10 mg/mL, and V is 1 mL. Plugging these values into the formula, we get:
7.5 mg / 10 mg/mL x 1 mL = 0.75 mL
Therefore, the final answer is: 0.75 mL
The nurse should administer 0.75 mL of morphine subcutaneous to the patient.

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 give a loading dose of ketorolac 30 mg IM, the nurse needs to calculate the volume of the injection solution.
The solution has a concentration of 15 mg/mL, which means that every 1 mL contains 15 mg of ketorolac.
To find the volume, the nurse can use the formula: volume = dose / concentration. Plugging in the values, we get: volume = 30 mg / 15 mg/mL = 2 mL.
Therefore, the nurse should administer 2 mL of ketorolac injection for a loading dose.
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 calculate the dosage of methotrexate for a client who has rheumatoid arthritis, the nurse needs to use the following formula:
D/H x Q = X, where D is the desired dose, H is the dose on hand, Q is the quantity of the solution, and X is the amount to administer.
In this case, D is 7.5 mg, H is 15 mg, and Q is 0.4 mL.
Plugging these values into the formula, we get: 7.5/15 x 0.4 = 0.2.
Therefore, the nurse should administer 0.2 mL of methotrexate subcutaneously for the client.

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
One way to calculate the IV pump rate is to divide the total volume of fluid by the total time in hours.
In this case, the client needs to receive 1,800 mL of 0.9% sodium chloride over 6 hours.
Therefore, the IV pump rate should be 1,800 mL / 6 hr = 300 mL/hr.
The nurse should ensure the IV pump is set to deliver 300 mL/hr of 0.9% sodium chloride to the client.

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 dosage of tobramycin for a client who weighs 85 kg, first we need to find the total daily dose by multiplying the weight by the dose per kg: 85 kg x 3 mg/kg/day = 255 mg/day.
Then, we need to divide the total daily dose by the number of doses per day to get the dose per administration: 255 mg/day / 3 doses/day = 85 mg/dose.
Finally, we need to use the concentration of the available solution to find the volume per dose by dividing the dose by the concentration: 85 mg/dose / 40 mg/mL = 2.125 mL/dose.
The nurse should administer 2.1 mL of tobramycin per dose to the client.

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 correct dosage of furosemide for an intramuscular injection, the nurse needs to divide the prescribed amount by the concentration of the drug.
In this case, the prescribed amount is 30 mg and the concentration is 10 mg/mL.
Therefore, the nurse should divide 30 mg by 10 mg/mL and get 3 mL.
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? (Select all that apply.)
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 dose of mycostatin oral suspension, the nurse needs to divide the prescribed amount of units by the concentration of units per mL.
In this case, the nurse should divide 400,000 units by 100,000 units/mL, which gives 4 mL.
The nurse should administer 4 mL of mycostatin oral suspension every 6 hours as ordered.
