A nurse is caring for a client who has a prescription for total parental nutrition (TPN).
Which of the following routes of administration should the nurse use?
Midline catheter.
Central venous access device.
Subcutaneous.
Intraosseous.
The Correct Answer is B
This is because TPN solutions are concentrated and can cause thrombosis of peripheral veins, so a central venous catheter is usually required. TPN should only be used when the intestine is unavailable or unable to absorb nutrients.
Choice A is wrong because a midline catheter is a type of peripheral catheter that can only be used for solutions with low or moderate osmolarity, not for TPN.
Choice C is wrong because subcutaneous administration is not a route for delivering TPN, which requires intravenous infusion.
Choice D is wrong because intraosseous administration is an emergency route for delivering fluids and drugs when intravenous access is not available, not for TPN.

Explanation
To calculate the amount of heparin to administer, use the formula:
mL of heparin=units available units ordered×1mL available
Substituting the values given in the question, we get:
mL of heparin=100004000×11=0.4
Therefore, the nurse should administer 0.4 mL of heparin.
Normal ranges for heparin therapy vary depending on the condition being treated and the laboratory method used to measure APTT.
A general range is 60 to 80 seconds or 1.5 to 2.5 times the control value.
