Give examples of clinical condition when BT is prolonged?
Prolonged bleeding time (BT) can occur in several clinical conditions, including thrombocytopenia, where a low platelet count leads to impaired hemostasis. Other examples include von Willebrand disease, which affects platelet function and adhesion, and certain medications like aspirin that inhibit platelet aggregation. Additionally, conditions such as liver disease can disrupt the production of clotting factors, further prolonging BT.
Clotting time nclex questions with answers and rationale?
Clotting time refers to the duration it takes for blood to form a clot after an injury or during a diagnostic test. In NCLEX questions, a common scenario might involve a patient with a prolonged clotting time, indicating potential issues like liver disease or anticoagulant therapy. For example, if a question states that a patient's clotting time is significantly prolonged, the correct answer may include monitoring for signs of bleeding and adjusting anticoagulant doses, as prolonged times can increase the risk of hemorrhage. The rationale is that understanding clotting mechanisms is essential for ensuring patient safety and effective management of bleeding disorders.
What color tube used for Activated clotting time with the clinical correlation heparin therapy?
sky blue.
Incubation time for Hemophilia?
Hemophilia is an inherited condition that prevents the blood from clotting properly. It does not have an incubation time; you are born with it. If you are having blood clotting problems and prolonged bleeding, you should see a physician for a blood test. There are a variety of things that can affect clotting, including too much aspirin, liver disease and some forms of cancer. DO NOT DELAY in seeking medical advice. Excessive bleeding can complicate recovery from accidents and surgery, and some of the causes are potentially fatal if not dealt with early. This is no joke.
How long does complete blood clotting take?
In clinical laboratory science it is common to wait 20-30 minutes for whole blood to clot totally in order to produce serum. The exact time depends on the container and the condition of the human subject.
Who should not have lung biopsies?
Lung biopsies should not be performed on patients who have a bleeding disorder or abnormal blood clotting because of low platelet counts, or prolonged prothrombin time (PT) or partial thromboplastin time (PTT).
What causes longer clotting time?
The main cause of a longer clotting time is the deficiency of the clotting factor in the blood. This is as a result of a damaged platelet in the blood cells.
Does alcohol slow clotting?
No it does not , it makes your blood thinner.
What are the effects of prolonged time in microgravity?
effects that prolonged time in microgravily
When Bleeding time is prolonged in all except A. Viper bite B. idiopathic thrombocytopenia C. Hemophilia A D. Von Willebrand disease?
In the viper bite clotting occurs rapidly. The clots can cause strokes and emboli in the lungs and legs. The others cause more rapid bleeding with bruising from a small bump to the skin and many nose bleeds. They lack an anticoagulation factor.
What is blood test APTT?
APTT, or Activated Partial Thromboplastin Time, is a blood test that measures the time it takes for blood to clot. It assesses the intrinsic and common pathways of coagulation, helping to evaluate bleeding disorders, the effectiveness of anticoagulant therapy, and the function of various clotting factors. A prolonged APTT can indicate issues such as hemophilia, liver disease, or the presence of anticoagulants. This test is commonly used in clinical settings to monitor patients on heparin therapy or to investigate unexplained bleeding.
Why is clotting time is so important?
Clotting time is important because it helps assess the body's ability to form blood clots efficiently. Abnormal clotting times can indicate bleeding disorders or increased risk of thrombosis. Monitoring clotting time is crucial in determining the effectiveness of anticoagulant therapy and guiding appropriate medical management.
