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
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
The correct answer is Choice A. After a below-the-knee amputation (BKA), pain management is crucial. Administering morphine 2-4 mg IV prn for pain is an appropriate physician’s order to implement. Pain can be severe after amputation, and effective pain management can improve patient comfort, reduce anxiety, and aid in recovery. Applying a figure of 8 pressure dressing starting day two post-operatively (Choice B) is not typically done after a BKA7. The operative dressing and splint should be maintained, and the wound should be kept clean, dry, and intact. Administering antibiotics as prescribed (Choice C) is important, but it is not the first action to take. Pain management is the priority immediately after surgery. Applying ice to the stump for 60-90 minutes (Choice D) is not typically done after a BKA7. The operative dressing and splint should be maintained, and the wound should be kept clean, dry, and intact.
Correct Answer is B
Explanation
Choice A rationale
Fewer doses of insulin may not necessarily be required with frequent self-monitoring of blood glucose. The need for insulin is determined by blood glucose levels, not the frequency of monitoring.
Choice B rationale
Frequent self-monitoring of blood glucose assists in gaining control over glucose levels. It can immediately tell you the effects of food choices, physical activity, and medication on blood glucose control.
Choice C rationale
While good blood glucose control can help minimize other health problems, frequent self- monitoring of blood glucose does not directly minimize other health problems.
Choice D rationale
Frequent self-monitoring of blood glucose is not necessarily the most cost-efficient method for glucose control. The cost efficiency depends on various factors, including the cost of testing supplies and the frequency of testing.
