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. Bright red blood in the stool typically indicates lower gastrointestinal bleeding, such as from hemorrhoids or anal fissures.

B) Correct. A tarry and sticky appearance of the stool, also known as melena, is characteristic of upper gastrointestinal bleeding. The dark color is due to the digestion of blood in the stomach.

C) Incorrect. A yellowish color of the stool is not associated with gastrointestinal bleeding. It can be related to other factors like diet or liver issues.

D) Incorrect. Clay-colored stools are pale and occur with problems in the biliary system, not with gastrointestinal bleeding.

A. The client has a history of hypertension. B. The client has been taking anticoagulant medication. C. The client is a regular blood donor. D. The client has a balanced diet.

Correct Answer is B

Explanation

A) Incorrect. While hypertension can be a risk factor for cardiovascular issues, it is not directly associated with an increased risk of hemorrhage.

B) Correct. Anticoagulant medication can interfere with the body's clotting mechanisms, making the client more susceptible to bleeding and hemorrhage.

C) Incorrect. Being a regular blood donor does not inherently increase the risk of hemorrhage unless the client donates too frequently, leading to anemia.

D) Incorrect. Having a balanced diet is essential for overall health, but it is not a specific risk factor for hemorrhage.
