Ati Med Surg NRSG 110 Exam ( 50 Questions)
You are instructed to administer tobramycin 35mg IM every 8 hours. The available supply is 40mg in a 1 mL vial.
How many mL’s should the nurse administer? Round your answer to the nearest tenth. Use a leading zero if it applies.
Do not use a trailing zero.
Correct Answer: 0.9
Step 1: We are instructed to administer tobramycin 35mg IM every 8 hours. The available supply is 40mg in a 1 mL vial.
Step 2: We need to find out how many mL’s should the nurse administer. Step 3: We can set up a proportion to solve this.
Step 4: If 40mg is equivalent to 1mL, then 35mg is equivalent to x mL. Step 5: Solving for x gives us x = (35mg ÷ 40mg) × 1mL.
Step 6: Calculating the above expression gives us x = 0.875 mL.
Step 7: Rounding our answer to the nearest tenth, we get 0.9 mL. So, the nurse should administer 0.9 mL.
