SELECT ALL THAT APPLY NCLEX PRACTICE QUESTIONS QUIZ 1 (50 ITEMS) Question 1 of 50 1. Question A patient is admitted to the same-day surgery unit for liver biopsy. Which of the following laboratory tests assesses coagulation? Select all that apply. • A. Partial thromboplastin time. • B. Prothrombin time. • C. Platelet count. • D. Hemoglobin • E. Complete Blood Count • F. White Blood Cell Count Correct Answer: A, B, and C Prothrombin time, partial thromboplastin time, and platelet count are all included in coagulation studies. The hemoglobin level, though important information prior to an invasive procedure like liver biopsy, does not assess coagulation. • Option A: Partial thromboplastin time (PTT) is the time it takes for a patient’s blood to form a clot as measured in seconds. It is used to measure the activity of the intrinsic pathway of the clotting cascade. PTT tests the function of all clotting factors except factor VII (tissue factor) and factor XIII (fibrin stabilizing factor). • Option B: Prothrombin time (PT) is one of several blood tests routinely used in clinical practice to evaluate the coagulation status of patients. More specifically, PT is used to evaluate the extrinsic and common pathways of coagulation, which would detect deficiencies of factors II, V, VII, and X, and low fibrinogen concentrations. • Option C: Platelet count is being assessed to determine the number of platelets in a sample of the blood as part of a health exam; to screen for, diagnose, or monitor conditions that affect the number of platelets, such as a bleeding disorder, a bone marrow disease, or other underlying conditions. • Option D: Hemoglobin is used to evaluate the hemoglobin content of your blood as part of a general health checkup; to screen for and help diagnose conditions that affect red blood cells (RBCs); if there is anemia (low hemoglobin) or polycythemia (high hemoglobin), and to assess the severity of these conditions and to monitor response to treatment. • Option E: The complete blood count (CBC) is a group of tests that evaluate the cells that circulate in blood, including red blood cells (RBCs), white blood cells (WBCs), and platelets (PLTs). The CBC can evaluate your overall health and detect a variety of diseases and conditions, such as infections, anemia and leukemia. • Option F: WBC count is used to screen for or diagnose a variety of conditions that can affect the number of white blood cells (WBCs), such as an infection, inflammation or a disease that affects WBCs; to monitor treatment of a disorder or to monitor therapy that is known to affect WBCs • 2. Question A patient is admitted to the hospital with suspected polycythemia vera. Which of the following symptoms is consistent with the diagnosis? Select all that apply. • A. Weight loss. • B. Prolonged clotting time. • C. Hypertension. • D. Headaches. • E. Polyphagia • F. Pruritus Correct Answer: B, C, D, and F.
