A nurse is caring for a client who reports an area of redness, warmth, tenderness, and pain in the right calf.
The nurse anticipates which of the following orders when notifying the provider of this finding?
Obtain impedance plethysmography.
Apply cold therapy to the affected leg.
Obtain a venous duplex ultrasound.
Monitor Homan's sign.
The Correct Answer is C
Choice A rationale:
Impedance plethysmography is a test that uses electrical signals to measure blood flow and can be used to detect deep vein thrombosis (DVT). However, it is not the first-line diagnostic tool for DVT.
Choice B rationale:
Cold therapy can help reduce inflammation and pain, but it is not a diagnostic measure for DVT.
Choice C rationale:
Venous duplex ultrasound is the most common test used to diagnose DVT. It uses sound waves to create pictures of the blood flowing through the veins in the leg.
Choice D rationale:
Homan’s sign is a physical examination finding that was traditionally used to diagnose DVT, but it is not reliable or specific.

Correct Answer is ["A","C","D","E"]
Explanation
Choice A rationale:
A distended bladder is a common sign of urinary retention, which can occur with prostatic hypertrophy. The enlarged prostate can block the flow of urine, causing the bladder to become distended.
Choice B rationale:
Dysuria, or painful urination, is not typically associated with urinary retention. It is more commonly seen in urinary tract infections.
Choice C rationale:
Feeling pressure is a common symptom of urinary retention. The pressure is caused by the buildup of urine in the bladder.
Choice D rationale:
Voiding small amounts frequently can be a sign of urinary retention. The bladder is not able to fully empty, so small amounts of urine are passed frequently.
Choice E rationale:
Tenderness over the symphysis pubis can be a sign of a distended bladder. The bladder is located just behind the symphysis pubis, so distention can cause tenderness in this area.
Correct Answer is ["D","E"]
Explanation

Choice C rationale:
Blurred vision can be a symptom of both hyperglycemia and hypoglycemia, but it’s more commonly associated with hyperglycemia.
Choice D rationale:
Moist, clammy skin is a symptom of hypoglycemia.
Choice E rationale:
Tachycardia, or a fast heartbeat, is a symptom of hypoglycemia.
