The nurse is preparing to administer enoxaparin 90 mg subcutaneously daily to a client admitted with a pulmonary embolism. The pharmacy provides a prefilled syringe labeled "Enoxaparin 100 mg/1 mL." How many milliliters should the nurse administer? (Enter numeric value only.)
The Correct Answer is ["0.9"]
To calculate the number of milliliters the nurse should administer, we can use the following formula: Dose to administer = Ordered dose / Available dose
In this case, the ordered dose is 90 mg and the available dose is 100 mg/1 mL. We can calculate the dose to administer as follows:
90 mg / 100 mg/1 mL = 0.9 mL.

Correct Answer is ["9"]
Explanation
To calculate the drop rate in gtts/minute, we can use the following formula:
Drop rate (gtts/minute) = (Volume (mL) x Drop factor) / Time (minutes)
Volume to be infused: 55 mL/hour
Drop factor: 10 gtt/mL
Time: 60 minutes/hour
(55 mL x 10 gtt/mL) / 60 minutes = 9.17 gtts/minute
We can round this value to the nearest whole number to get 9gtts/min
Correct Answer is ["56"]
Explanation
Answer: 56 gtt/min.
Rationale:
To calculate the infusion rate in gtt/min, we'll use the following formula:
Infusion Rate (gtt/min) = Volume (mL) / Time (min) x Drop Factor (gtt/mL)
1. Convert volume to mL:
2 liters = 2000 mL
2. Convert time to minutes:
12 hours = 12 x 60 = 720 minutes
3. Plug in the values:
Infusion Rate (gtt/min) = 2000 mL / 720 min x 20 gtt/mL
4. Calculate:
Infusion Rate (gtt/min) ≈ 55.56 gtt/min
5. Round to the nearest whole number:
Infusion Rate (gtt/min) ≈ 56 gtt/min
Therefore, the nurse should regulate the infusion to 56 gtt/min.
