The client diagnosed with deep vein thrombosis asks the nurse, "How does heparin work to help with my blood clot?" Which response is most accurate? "Heparin:

makes the blood less thick and easier to flow."

does not thin the blood: it prevents new clots from forming."

decreases the number of platelets so the blood clots more slowly."

dissolves the clot and decreases the formation of platelets."

Answer and Explanation

The Correct Answer is B

A.   Heparin does not actually "thin" the blood in the sense of reducing viscosity. Instead, it works by inhibiting certain factors in the coagulation cascade, preventing clot formation. Thus, this response does not accurately describe how heparin functions.

B.   Heparin works by activating antithrombin III, which inhibits thrombin and factor Xa, thereby preventing the formation of new clots. It does not dissolve existing clots but helps to prevent the enlargement of existing ones and the formation of new clots.
C.   Heparin does not decrease the number of platelets; rather, it interferes with the clotting process by inhibiting specific clotting factors. Platelets may still be present, but their ability to form clots is inhibited by the action of heparin.
D.   Heparin does not dissolve existing clots; that function is typically performed by thrombolytic agents. Heparin primarily prevents new clot formation and the extension of existing clots. Additionally, it does not decrease platelet formation.

Correct Answer is D

Explanation

A. This is a symptom of urinary tract infection, not renal colic.
B. This indicates kidney damage, which may occur as a complication of untreated kidney stones, but it's not a typical symptom of renal colic itself.
C. This is not a symptom of renal colic.
D. This is a classic symptom of renal colic, which is caused by the passage of a kidney stone through the ureter. The pain is often described as excruciating and can radiate to the groin or testicle.

A. prevents bleeding and covers the incision. B. decreases phantom limb pain. C. limits the formation of blood clots. D. shapes the soft tissue and minimizes edema.

Correct Answer is D

Explanation

A. While an elastic bandage can provide some compression to control bleeding, its primary purpose post-amputation is not to prevent bleeding but to support the healing process. It does help cover the incision, but this is not its main function in the context of shaping the stump.
B. Phantom limb pain is a common phenomenon after amputation, where the patient feels sensations in the amputated limb. Wrapping the stump may provide some psychological comfort, but the elastic bandage does not directly decrease phantom limb pain.
C. While adequate compression can help with circulation, the primary function of wrapping the stump is not to prevent blood clots. Preventing blood clots is more relevant to immobilization and other measures, particularly in the early postoperative period.
D. The elastic bandage helps to compress the soft tissue of the stump, promoting a well-shaped residual limb. This shaping is important for fitting prosthetics later and helps minimize edema (swelling) in the area post-surgery.
