A client with a history of bleeding disorders presents to the emergency department with excessive bleeding from a minor cut. Which laboratory test should the nurse monitor to assess the client's clotting function?

Complete blood count (CBC)

Serum electrolytes

Prothrombin time (PT)

Blood glucose level

Answer and Explanation

The Correct Answer is C

A) Incorrect. A complete blood count (CBC) provides information about the client's red blood cells, white blood cells, and platelets, but it does not directly assess clotting function.

B) Incorrect. Serum electrolytes help assess the body's fluid balance and various organ functions, but they do not specifically indicate clotting function.

C) Correct. Prothrombin time (PT) is a measure of the time it takes for the blood to clot, primarily assessing the function of the extrinsic pathway of coagulation. It is an essential test in evaluating clotting disorders.

D) Incorrect. Blood glucose level is not directly related to clotting function and is more indicative of a client's metabolic status.

Correct Answer is B

Explanation

A) Incorrect. Swelling and bruising around the wound are common signs of external bleeding and do not directly indicate internal bleeding.

B) Correct. Cool and pale skin in the extremities may be indicative of vasoconstriction and reduced blood flow, which can occur in response to internal bleeding.

C) Incorrect. Blood oozing from the wound site is a typical sign of external bleeding and does not necessarily indicate internal bleeding.

D) Incorrect. Visible blood clot formation at the wound site is a normal part of the body's hemostatic response to control external bleeding and does not directly suggest internal bleeding.

A. Excessive production of platelets. B. Inadequate production of clotting factors. C. Uncontrolled activation of the clotting cascade. D. Decreased platelet count.

Correct Answer is C

Explanation

A) Incorrect. In DIC, platelet consumption and depletion occur due to widespread clot formation, leading to a decreased platelet count.

B) Incorrect. While inadequate production of clotting factors could lead to bleeding disorders, DIC is characterized by uncontrolled activation of the clotting cascade, leading to excessive clot formation initially, followed by consumption of clotting factors and increased bleeding.

C) Correct. DIC is a serious condition in which there is widespread activation of the clotting cascade, causing the formation of numerous small blood clots throughout the body. These clots can lead to organ dysfunction and excessive bleeding.

D) Incorrect. DIC is associated with decreased platelet count due to the consumption of platelets in the formation of multiple small clots.
