The nurse is caring for a client who is being evaluated for possible deep vein thrombosis of the right extremity. Which laboratory result is of most concern to the nurse?
Activated Partial Thromboplastin Time (aPTT) of 25.
D-dimer of 500 ng/mL.
Prothrombin Time (PT) of 14 seconds.
Platelet count of 148,000 uL.
The Correct Answer is B
Choice A rationale
Activated Partial Thromboplastin Time (aPTT) of 25 is within the normal range (25-35 seconds) and is not directly related to deep vein thrombosis (DVT)89.
Choice B rationale
A D-dimer level of 500 ng/mL is elevated (normal range is typically less than 250 ng/mL), which can indicate the presence of a clot, such as in DVT8910.
Choice C rationale
Prothrombin Time (PT) of 14 seconds is within the normal range (11-13.5 seconds) and is not directly related to DVT89.
Choice D rationale
A platelet count of 148,000 uL is within the normal range (150,000-450,000 uL) and is not directly related to DVT89.

Correct Answer is D
Explanation
Choice A rationale
While it’s important for clients to understand their medications, not having received proper education on this medication is not a reason to withhold cefazolin.
Choice B rationale
Completing a full course of an aminoglycoside antibiotic does not contraindicate the use of cefazolin.
Choice C rationale
Being afebrile does not contraindicate the use of cefazolin. Antibiotics are used to treat bacterial infections, not just to reduce fever.
Choice D rationale
A prior anaphylactic reaction to penicillin is a contraindication for administering cefazolin. Cefazolin is a cephalosporin, and there is a risk of cross-reactivity and potential allergic reaction in clients who have a history of severe penicillin allergy.
Correct Answer is C
Explanation
Choice A rationale
While a past medical history of myocardial infarction does increase the risk of deep vein thrombosis (DVT), it is not the highest risk factor among the options provided. Other factors such as immobility, surgery, and certain medical conditions can pose a higher risk.
Choice B rationale
Postoperative patients, such as those who have had a laparoscopic knee replacement, are at an increased risk for DVT due to periods of immobility and changes in blood flow and clotting.
However, the risk is not as high as in patients who have undergone major open abdominal surgery.
Choice C rationale
Patients who have undergone major open abdominal surgery are at the highest risk for the development of DVT among the options provided. The surgery itself, along with the postoperative period of immobility, significantly increases the risk of DVT34567.
Choice D rationale
While peptic ulcers can be associated with certain risk factors for DVT, such as age and immobility due to pain, they do not pose as high a risk as major open abdominal surgery.
