Heparin Infusion Review.
A nurse is reviewing the laboratory results of a client who is receiving heparin by continuous IV infusion.
Which of the following results indicates the nurse should decrease the infusion rate?
Erythrocyte sedimentation rate 18 mm/hr.
aPTT 90 seconds.
INR.2.
Platelets 350,000/mm.
The Correct Answer is B
Heparin is an anticoagulant medication that is used to decrease the clotting ability of the blood and help prevent harmful clots from forming in blood vessels.
The activated partial thromboplastin time (aPTT) is a laboratory test commonly used to monitor unfractionated heparin therapy.
An aPTT value of 90 seconds is above the therapeutic range and indicates that the heparin infusion rate should be decreased.
Choice A is wrong because Erythrocyte sedimentation rate 18 mm/hr, is not the correct answer because it is not used to monitor heparin therapy.
Choice C is wrong because INR.2, is not the correct answer because it falls within the normal range for INR values and is not used to monitor heparin therapy.
Choice D is wrong because Platelets 350,000/mm, is not the correct answer because it falls within the normal range for platelet counts and is not used to monitor heparin therapy.

Explanation
Total parenteral nutrition (TPN) is a highly concentrated solution that provides nutrients to the body intravenously.
It is typically administered through a central venous access device, such as a central venous catheter or a peripherally inserted central catheter (PICC), because it can irritate the walls of smaller veins.
Choice B is wrong because Midline catheter, is not an appropriate route for TPN administration because it is not a central venous access device.
Choice C is wrong because Subcutaneous, is not an appropriate route for TPN administration because it is not given intravenously.
Choice D is wrong because Intraosseous, is not an appropriate route for TPN administration because it is typically used in emergency situations when intravenous access cannot be obtained.
