A client's assessment data indicates a potential bleeding problem. What laboratory studies will be used to isolate the problem? Select all that apply
1. Platelet count
2. Prothrombin time (PT)
3. Bleeding time
4. Activated partial thromboplastin time (aPTT)
5. Fibrinogen split products
1. Platelet count
2. Prothrombin time (PT)
3. Bleeding time
4. Activated partial thromboplastin time (aPTT)
Rationale: Platelet count. The platelet count is a test that determines the number of platelets in the blood, and depicts clotting potential. Prothrombin time (PT). Prothrombin time depicts extrinsic coagulation factors. Bleeding time. Bleeding time reflects platelet interaction and capillary constriction. Activated partial thromboplastin time (aPTT). aPTT reflects intrinsic coagulation factors critical to the clotting cascade. Fibrinogen split products. This is useful in detection of DIC, which is triggered by an injury or event leading to persistent activation of the clotting cascade, not by a bleeding problem per se.
