A nurse is preparing to administer enoxaparin 55 mg subcutaneous to a client who has a deep-vein thrombosis after undergoing a cesarean birth. Available is enoxaparin solution for injection 60 mg/0.6 mL. How many mL should the nurse administer?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.6"]
60mg=0.6
55mg= 55*0.6/60
Volume (mL) = 0.55 mL
Rounding to the nearest tenth, the nurse should administer 0.6 mL of enoxaparin solution to the client.

Correct Answer is ["26"]
Explanation
1.7mg/min = 1.7*60 = 102mg/hr 1g=1000mg
1000mg= 250mls of lidocaine dextrose 102mg = 102*250/1000 = 25.5ml/hr
Rounded off to the nearest whole number, the pump should be set deliver 26 mL/hr.
Correct Answer is ["2.9"]
Explanation
Let’s calculate the IV pump rate for administering dobutamine to a preterm newborn.
Step 1 is to convert the dose from mcg/kg/min to mg/kg/min. We know that 1 mg = 1000 mcg, so we have:
12 mcg/kg/min ÷ 1000 = 0.012 mg/kg/min
Step 2 is to calculate the total amount of dobutamine the newborn needs per minute:
0.012 mg/kg/min × 2 kg = 0.024 mg/min
Step 3 is to convert this to an hourly rate:
0.024 mg/min × 60 min/hr = 1.44 mg/hr
Step 4 is to calculate the volume of the solution that contains this amount of dobutamine. We know that 250 mg of dobutamine is dissolved in 500 mL of solution, so:
(1.44 mg/hr ÷ 250 mg) × 500 mL = 2.88 mL/hr
So, the nurse should set the IV pump to deliver approximately 2.9 mL/hr (rounded to the nearest tenth).
