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
Testing the stool for occult blood is not typically necessary for a client taking an antibiotic that causes diarrhea. While antibiotics can cause changes in the gastrointestinal tract, they do not typically cause gastrointestinal bleeding.
Choice B rationale
Increasing roughage in the diet can help bulk up the stool and may help alleviate some cases of diarrhea. However, it’s not the primary recommendation for a client taking an antibiotic that causes diarrhea.
Choice C rationale
Requesting the physician for a different antibiotic if diarrhea persists can be an appropriate action. However, this is typically recommended after other strategies, such as adding probiotics to the diet, have been tried.
Choice D rationale
Adding yogurt to the diet is often recommended for clients taking an antibiotic that causes diarrhea. Yogurt contains probiotics, which can help restore the balance of good bacteria in the gut and alleviate diarrhea.
Correct Answer is A
Explanation
Choice A rationale
After a femoral-popliteal bypass, the client should be placed in a supine position with the right leg extended and flat. This position helps to prevent kinking and occlusion of the graft, which could lead to complications such as graft thrombosis.
Choice B rationale
High-Fowler’s position with the right leg extended is not recommended. This position could put strain on the surgical site and potentially compromise the graft.
Choice C rationale
Supine with the right leg flexed at a 45-degree angle is not advised. Flexing the leg could lead to kinking of the graft and subsequent complications.
Choice D rationale
Semi-Fowler’s with the right leg on two pillows is not the optimal position. While elevation can help with swelling, excessive elevation could potentially compromise blood flow to the graft.
