Question 19 1 pts A safe IV push infusion rate of protamine sulfate is 5 mg/min. Protamine sulfate is available in a supply dosage of 10 mg/ml. To administer 50 mg IV push, prepare mL and slowly injec
t over approximately _____ minutes.
To administer 50 mg of protamine sulfate IV push, you would need to prepare 5 mL of the solution.
Since the recommended safe infusion rate is 5 mg/min, you would slowly inject the 5 mL over approximately 10 minutes (dividing the total dose of 50 mg by the infusion rate of 5 mg/min).
To administer 50 mg of protamine sulfate using an IV push infusion rate of 5 mg/min, you will need to prepare a certain amount of the 10 mg/ml solution and slowly inject it.
First, let's calculate the total volume (ml) needed.
Given that the supply dosage of protamine sulfate is 10 mg/ml and you need to administer 50 mg, you can calculate the volume required using the formula:
Volume = Amount / Concentration
Volume = 50 mg / 10 mg/ml
Volume = 5 ml
So, you will need to prepare 5 ml of the protamine sulfate solution.
To slowly inject the solution over the desired infusion rate of 5 mg/min, you will need to divide the total volume by the infusion rate:
Time (in minutes) = Volume / Infusion rate
Time = 5 ml / 5 mg/min
Time = 1 minute
Therefore, you will need to prepare 5 ml of the protamine sulfate solution and slowly inject it over a period of 1 minute.
To calculate the mL of protamine sulfate needed to administer 50 mg IV push, you need to determine the volume required based on the concentration of the supplied dosage.
Given:
Safe IV push infusion rate = 5 mg/min
Supply dosage = 10 mg/ml
Amount to administer = 50 mg
To calculate the mL of protamine sulfate needed, you can use the following formula:
Volume (in mL) = Amount (in mg) / Concentration (in mg/mL)
In this case, the calculation would be:
Volume = 50 mg / 10 mg/mL
By dividing 50 mg by 10 mg/mL, you can see that you require 5 mL of protamine sulfate.
Once you have prepared the 5 mL, you can then slowly inject it into the patient as per the administration instructions.
