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.)
The Correct Answer is ["300"]
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.

Correct Answer is ["10"]
Explanation
To calculate the dose of amoxicillin oral suspension for a client, the nurse needs to use the following formula: Dose (mL) = Desired dose (mg) / Available dose (mg/mL) x Volume (mL).
In this case, the desired dose is 500 mg, the available dose is 250 mg/5 mL, and the volume is 5 mL.
Therefore, the dose (mL) = 500 mg / (250 mg/5 mL) x 5 mL = 10 mL.
The nurse should administer 10 mL of amoxicillin oral suspension to the client.
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.
