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 D
Explanation
The nurse should instruct the client to monitor and report bruising as an adverse effect of taking clopidogrel.
Clopidogrel increases the risk of bleeding, which can be severe or life- threatening.
Choice A is wrong because blurred vision is not a common adverse effect of clopidogrel.
Choice B is wrong because constipation is not a common adverse effect of clopidogrel.
Choice C is wrong because weight loss is not a common adverse effect of clopidogrel.
Correct Answer is C
Explanation
First, convert the client’s weight from pounds to kilograms: 121 lb /.2 = 55 kg. Then, calculate the dose in mg: 1 mg/kg * 55 kg = 55 mg.
Finally, use the ratio of available enoxaparin to calculate the volume to administer: (55 mg / 60 mg) * 0.6 mL = 0.55 mL.
Rounded to the nearest tenth, this is 0.6 mL.
Choice A is wrong because it is less than the calculated dose of 0.6 mL.
Choice B is wrong because it is equal to the calculated dose of 0.6 mL but not rounded to the nearest tenth.
Choice D is wrong because it is greater than the calculated dose of 0.6 mL.
