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.)
The Correct Answer is ["3"]
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.

Correct Answer is ["500"]
Explanation
To calculate the infusion rate for lactated Ringer's solution, the nurse should use the following formula: infusion rate (mL/hr) = volume (mL) / time (hr).
Since the volume is 250 mL and the time is 0.5 hr (30 min), the infusion rate is 250 / 0.5 = 500 mL/hr.
The nurse should set the IV pump to deliver 500 mL/hr of lactated Ringer's solution to the patient.
Correct Answer is ["2.1"]
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.
