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.

Correct Answer is A
Explanation
Total parenteral nutrition (TPN) is a method of administration of essential nutrients to the body through a central vein.
TPN solutions are customized for each client’s needs, including the exact amount of calories and nutrients necessary for total nutritional needs.
Monitoring the client’s weight daily is important to determine if nutritional goals are being met and to assess fluid volume status.
Choice B is wrong because TPN solutions are concentrated and can cause thrombosis of peripheral veins, so they require a central venous catheter and should not be hung to gravity to infuse.
Choice C is wrong because TPN solution should not be titrated to blood pressure.
Choice D is wrong because the client’s blood glucose level should be monitored more frequently than weekly when receiving TPN.
Correct Answer is A
Explanation
The nurse should withhold the dose of propranolol and notify the provider.
Using propranolol together with albuterol may reduce the benefits of both medications, since they have opposing effects in the body.
In addition, propranolol can sometimes cause narrowing of the airways, which may worsen breathing problems or trigger severe asthmatic attacks.
Choice B is wrong because there is no known interaction between albuterol and isosorbide mononitrate.
Choice C is wrong because there is no known interaction between albuterol and pantoprazole.
Choice D is wrong because there is no known interaction between albuterol and montelukast.
