A nurse is to preparing to administer cefazolin 1 g by intermittent IV bolus over 30 min. Available is cefazolin 1 g in 100 ml dextrose 5% in water (DSW). The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion 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.)

Answer and Explanation

The Correct Answer is ["33"]

- To calculate the gtt/min, use the formula: gtt/min = (volume in mL x drop factor) / time in min

- Plug in the values from the question: gtt/min = (100 mL x 10 gtt/mL) / 30 min - Simplify and solve: gtt/min = 1000 gtt / 30 min

- Divide both sides by 30: gtt/min = 33.33 gtt/min

- Round to the nearest whole number: gtt/min = 33 gtt/min

- The nurse should set the manual IV infusion to deliver 33 gtt/min
