Question1Which statement best describes the function of fibrinogen?  Plays a key role in forming blood clots Explanation:Fibrinogen, the largest share of plasma protein, plays a key role in forming blood clots. It can be transformed from a liquid to fibrin, a solid that controls bleeding. Globulins function primarily as immunologic agents by preventing or modifying some types of infectious diseases. On the other hand, albumin helps maintain the osmotic pressure that retains fluid in the vascular compartment. Question3Which term refers to a form of white blood cell involved in immune response?  Lymphocyte Explanation:Mature lymphocytes are the principal cells of the immune system, producing antibodies and identifying other cells and organisms as “foreign.” Both B and T lymphocytes respond to exposure to antigens. Granulocytes include basophils, neutrophils, and eosinophils. A spherocyte is a red blood cell without central pallor, seen with hemolysis. A thrombocyte is a platelet. Question5The physician performs a bone marrow biopsy from the posterior iliac crest on a client with pancytopenia. What intervention should the nurse perform after the procedure?  Apply pressure over the site for 5–7 minutes Explanation:Hazards of either bone marrow aspiration or biopsy include bleeding and infection. The risk of bleeding is somewhat increased if the client’s platelet count is low or if the client has been taking a medication (e.g., aspirin) that alters platelet function. After the marrow sample is obtained, pressure is applied to the site for several minutes. The site is then covered with a sterile dressing. Question7The nurse should notify the healthcare provider before administering fresh frozen plasma (FFP) based on which assessment finding?  Jugular venous distention Explanation:During the pre-transfusion assessment, the nurse should carefully inspect for any signs of cardiac failure, such as jugular venous distention. The sclera should be examined for icterus; white is an expected finding. Weak pedal pulses would be a sign of cardiac failure. Tenting skin turgor is a sign of dehydration; low vascular volume would be a cause for transfusion, not a contraindication. Question8A patient will need a blood transfusion for the replacement of blood loss from the gastrointestinal tract. The patient states, “That stuff isn’t safe!” What is the best response from the nurse?  “I understand your concern. The blood is carefully screened but is not completely risk free.” Explanation:Despite advances in donor screening and blood testing, certain diseases can still be transmitted by transfusion of blood components (Chart 32-4). Question9The body responds to infection by increasing the production of white blood cells (WBCs). The nurse should evaluate the differential count for what type of WBCs, which are the first WBCs to respond to an inflammatory event?  Neutrophils Explanation:Neutrophils, the most abundant type of white blood cell, are the first of the WBCs to respond to infection or inflammation. The normal value is 3,000 to 7,000/cmm (males) and 1,800 to 7,700/cmm (females).
