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.
What changes are seen in clotting time in purpura and hemophilia?
In purpura, which involves bleeding due to vascular abnormalities or platelet issues, the clotting time may remain normal since the primary problem is not with the clotting factors. In hemophilia, a genetic disorder characterized by deficiencies in specific clotting factors (most commonly Factor VIII or IX), the clotting time is prolonged, particularly in tests like the activated partial thromboplastin time (aPTT). This indicates a delayed clotting ability, leading to increased bleeding tendencies.
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.
What are the clinical condition in which bleeding time is prolong?
Prolonged bleeding time can occur in several clinical conditions, including thrombocytopenia (low platelet count), von Willebrand disease (a genetic disorder affecting platelet function), and platelet dysfunction syndromes. Other factors such as the use of certain medications (like aspirin or anticoagulants) can also lead to extended bleeding times. Additionally, conditions that affect blood vessel integrity, such as scurvy or certain connective tissue disorders, may contribute to prolonged bleeding times.
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 does a Prothrombin time of 19 indicate?
A Prothrombin time (PT) of 19 seconds is longer than the typical range, which is usually between 11 to 13.5 seconds. This prolonged PT can indicate a potential issue with blood coagulation, such as a deficiency in clotting factors, liver dysfunction, or the effects of anticoagulant medications like warfarin. It's important to evaluate this result in the context of other tests and clinical findings to determine the underlying cause.
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.
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.
