Step 1 is to determine the amount of medication needed. The order is for 1 g and the available medication is 1 g/10 mL. So, we calculate 1 g ÷ 1 g/10 mL = 10 mL. Since 1 tsp is approximately 5 mL, we then calculate 10 mL ÷ 5 mL/tsp = 2 tsp. So the correct answer is 2 tsp.
A nurse is preparing to administer dextrose 5% in 0.45% sodium chloride 1 L with magnesium sulfate 1 g to infuse IV bolus over 12 hr. The nurse should set the IV pump 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.). mL/hr.
Full Explanation
Step 1 is to calculate the total volume to be infused. The total volume is 1 L, which is equal to 1000 mL. Step 2 is to divide the total volume by the total time. The total time is 12 hours. So, the calculation is 1000 mL ÷ 12 hr = 83.33 mL/hr.
So, the correct answer is 83 mL/hr, after rounding to the nearest whole number.
