A nurse is reviewing the laboratory results of a postpartum client who has idiopathic thrombocytopenic purpura (ITP).
Which of the following findings should the nurse expect?
Decreased platelet count. ITP is a disorder that causes low levels of platelets due to immune system malfunction or increased breakdown of platelets.
Platelets are blood cells that control bleeding and prevent bruising. Normal platelet count ranges from 150,000 to 450,000 per microliter of blood.
Increased prothrombin time means prolonged clotting time, which is not a feature of ITP. Prothrombin time measures how long it takes for the blood to clot and is affected by factors such as liver disease, vitamin K deficiency, or blood-thinning medications.
Decreased fibrinogen level means reduced ability to form blood clots, which is not a feature of ITP. Fibrinogen is a protein that helps the blood to clot and is affected by factors such as liver disease, inflammation, infection, or trauma.
Increased partial thromboplastin time means prolonged clotting time, which is not a feature of ITP. Partial thromboplastin time measures how long it takes for the blood to clot and is affected by factors such as hemophilia, lupus, or blood-thinning medications.
The correct answer is choice A. Decreased platelet count. ITP is a disorder that causes low levels of platelets due to immune system malfunction or increased breakdown of platelets.
Platelets are blood cells that control bleeding and prevent bruising. Normal platelet count ranges from 150,000 to 450,000 per microliter of blood.
Choice B is wrong because increased prothrombin time means prolonged clotting time, which is not a feature of ITP. Prothrombin time measures how long it takes for the blood to clot and is affected by factors such as liver disease, vitamin K deficiency, or blood-thinning medications.
Choice C is wrong because decreased fibrinogen level means reduced ability to form blood clots, which is not a feature of ITP. Fibrinogen is a protein that helps the blood to clot and is affected by factors such as liver disease, inflammation, infection, or trauma.
Choice D is wrong because increased partial thromboplastin time means prolonged clotting time, which is not a feature of ITP. Partial thromboplastin time measures how long it takes for the blood to clot and is affected by factors such as hemophilia, lupus, or blood-thinning medications.
