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
Ceftriaxone is contraindicated for this client because it is a cephalosporin antibiotic, which has a similar structure to penicillin and can cause cross-reactivity in individuals with a penicillin allergy.
Choice A is wrong because Vancomycin is not a beta-lactam antibiotic and does not have cross-reactivity with penicillin.
Choice B is wrong because Clarithromycin is a macrolide antibiotic and does not have cross-reactivity with penicillin.
Choice C is wrong because Metronidazole is a nitroimidazole antibiotic and does not have cross-reactivity with penicillin.
Correct Answer is B
Explanation
Levothyroxine is a thyroid hormone medicine used to treat hypothyroidism (low thyroid hormone)1.
It works by replacing thyroid hormone that is normally produced by the body.
Cold intolerance is a common symptom of hypothyroidism2, so if the client reports that they are not as cold as they used to be, it indicates that the medication is working and their hormone levels are returning to a healthy range.
Choice A is wrong because constipation is a common symptom of hypothyroidism2, so taking a laxative for constipation does not indicate a therapeutic response to the medication.
Choice C is wrong because weight loss without dieting can be a side effect of taking too much levothyroxine.
Choice D is wrong because sleeping more than usual can be a symptom of hypothyroidism2, so it does not indicate a therapeutic response to the medication.
