A nurse is preparing to administer a heparin infusion of 25,000 units in 250 mL of normal saline at a rate of 1000 units per hour for a client diagnosed with a Deep Vein Thrombosis (DVT). The client’s initial activated partial thromboplastin time (aPTT) value is 35 seconds.

Which laboratory result would indicate that the aPTT is at a therapeutic level?

30 seconds

45 seconds

60 seconds

75 seconds

Answer and Explanation

The Correct Answer is D

Step 1 is to understand the therapeutic range for aPTT when a patient is on heparin therapy. The therapeutic range for aPTT is 1.5 to 2.5 times the normal value. Given that the normal aPTT value is around 30-40 seconds, the therapeutic range would be approximately 45-100 seconds. Therefore, an aPTT value of 75 seconds falls within this therapeutic range, indicating that the heparin therapy is effective.

Correct Answer is A

Explanation

Step 1 is: According to the information from the search results, regular insulin, such as the 16 units prescribed to the patient, starts working 30 minutes to 1 hour after administration and peaks in 2 to 5 hours. Therefore, the patient should expect the insulin peak 2 to 4 hours after administration.

A. Elevate the feet for 30 minutes after walking. B. Avoid exercise that increases the heart rate. C. Continue walking to the point of pain. D. Do not walk if a leg ulcer develops.

Correct Answer is C

Explanation

Choice A rationale

Elevating the feet for 30 minutes after walking is not specifically beneficial for a patient with peripheral arterial disease (PAD). While elevation can help with conditions like edema, it does not directly address the issues associated with PAD12.

Choice B rationale

Avoiding exercise that increases the heart rate is not the best advice for a patient with PAD. Exercise, including activities that increase heart rate, can actually be beneficial. It can help improve circulation, which is often compromised in PAD12.

Choice C rationale

Continuing to walk to the point of pain is beneficial for patients with PAD. Walking, especially at a high intensity, can help improve symptoms of PAD. It can increase blood flow and oxygen supply to the muscles, which can help manage PAD symptoms.

Choice D rationale

While it’s important to care for any ulcers that develop and seek medical attention, stopping walking altogether if a leg ulcer develops is not necessary. Walking is a low-impact activity that can help improve mobility over time.
