A nurse is preparing to administer cefazolin 1 g intermittent IV bolus in 0.9% sodium chloride 250 mL over 30 min. The drop factor on the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV flow rate to deliver how many gtt/min? (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 ["83"]
To calculate the manual IV flow rate, the nurse needs to use the following formula:
Flow rate (gtt/min) = Volume (mL) x Drop factor (gtt/mL) / Time (min)
Plugging in the given values, we get:
Flow rate (gtt/min) = 250 mL x 10 gtt/mL / 30 min
Flow rate (gtt/min) = 2500 gtt / 30 min
Flow rate (gtt/min) = 83.33 gtt/min
The nurse should set the manual IV flow rate to deliver 83 gtt/min.

Correct Answer is ["2.1"]
Explanation
To calculate the dosage of tobramycin for a client who weighs 85 kg, the nurse should first determine the total daily dose by multiplying the weight by the prescribed dose per kg.
This gives 3 mg/kg/day x 85 kg = 255 mg/day.
Next, the nurse should divide the total daily dose by the number of doses per day to get the dose per administration.
This gives 255 mg/day / 3 doses/day = 85 mg/dose.
Finally, the nurse should use the formula D/H x Q to find the volume to be administered, where D is the desired dose, H is the dose on hand, and Q is the quantity on hand.
This gives 85 mg/dose / 40 mg/mL x 1 mL = 2.125 mL/dose.
Therefore, the nurse should administer 2.1 mL of tobramycin per dose to the client.
Correct Answer is D
Explanation
A. Use 0.9% sodium chloride solution as a diluent:
The label does not mention the use of 0.9% sodium chloride solution. It specifically provides directions for adding water for reconstitution. Therefore, using sodium chloride solution is not consistent with the instructions.
B. Store the medication at room temperature following reconstitution:
The label clearly states that the reconstituted suspension "Must be refrigerated." Storing it at room temperature contradicts the provided instructions.
C. Roll the vial gently in hands to mix the medication:
The label instructs to "Shake vigorously" to wet the powder, not to roll it gently. Shaking is the recommended method for mixing the medication according to the label.
D. Discard any remaining medication after 10 days:
This is the correct action according to the label. The label specifies that the reconstituted suspension should be discarded after 10 days, emphasizing the importance of not using the medication beyond that period for safety reasons.
