Chapter 14, Disorders of Platelets, Hemostasis, and CoagulationMultiple Choice
Identify the choice that best completes the statement or answers the question.
1. The nurse is caring for a client who reports with severe bleeding. The primary health-care provider
prescribes a diagnostic test that would measure the time taken for the blood to clot and examine the
extrinsic pathway of coagulation cascade. Which diagnostic test does the nurse expect to be
performed?
1. Fibrinogen test
2. Activated partial thromboplastin time test
3. Platelet aggregation test
4. Prothrombin time test
2. A client reports shortness of breath and severe pain in the back, chest, and muscles. Which condition
does the nurse recognize as a possible diagnosis for the client?
1. Hemophilia B
2. Hemophilia A
3. Disseminated intravascular coagulation
4. Von Willebrand disease
3. A client with hemolytic-uremic syndrome reports fever, abdominal pain, pale skin, bruising, and
bleeding of the skin. Which medication or treatment will be beneficial for the client?
1. Supportive treatment wiN thUdRiaSlyIsN

2. Aspirin and antiplatelet drugs
3. Desmopressin acetate
4. Immunomodulatory drugs
4. An adult client who presents with symptoms of redness, heat, and pain in the joints undergoes a
complete blood count test. The blood report shows an increased white blood cell count. Which
condition does this indicate?
1. Inflammation
2. Anemia
3. Increased bleeding tendency
4. Pulmonary embolism
5. A client reports a sensation of stomach fullness, fatigue, nausea, vomiting, and abdominal bloating.
The client is diagnosed with stomach cancer. Which prescribed medication requires the nurse to
closely monitor the client for clotting issues?
1. Cisplatin
2. Ticlopidine
3. Cyclosporine
4. Tacrolimus
6. While reviewing a client’s medical history, the nurse understands that the client is at risk of bleeding
because the client’s platelet count is 80,000/uL. Which condition is this?
1. Thrombocytosis
2. Thrombocytopenia
, 3. Thrombus
4. Thrombosis
7. Which statement is true regarding megakaryocytes?
1. They are invisible in bone marrow.
2. They have a nucleus.
3. They can synthesize proteins.
4. They mature into platelets.
8. The nurse is providing care for a client diagnosed with heart failure, which inhibits ambulatory
activities. Which factor does the nurse recognize as the greatest risk for enhanced platelet activity
with this client?
1. Disturbances in blood flow
2. Stasis of blood flow
3. Increase in procoagulation factors
4. Decrease in anticoagulation factors
9. The nurse is providing care for a client receiving emergency care for a condition presenting with the
symptoms of a stroke. Which characteristic of the involved clotting pathway does the nurse
recognize?
1. The extrinsic pathway is stimulated because of trauma
2. Diagnostic testing will involve both the prothrombin time (PT) and international
normalized ratio (INR)
3. Injury has occurred to the endothelial lining of a vessel

10. Which does the nurse recognize as the best intervention for immediately lowering the platelet count
to safer levels in a client diagnosed with severe life-threatening thrombocytosis?
1. Administering aspirin in a small dose
2. Providing clopidogrel to inhibit blood clotting
3. Administering hydroxyurea to lower the platelet count
4. Performing pheresis to remove whole blood from the donor
11. Two clients are admitted into an acute care unit for clotting-related conditions. One of the clients is
prescribed the drug fondaparinux, whereas the other client is prescribed dabigatran. In which way is
fondaparinux different from dabigatran?
1. Fondaparinux is administered by subcutaneous injection.
2. Fondaparinux is an oral form of anticoagulant.
3. Fondaparinux is used to prevent stroke in clients with atrial fibrillation.
4. Fondaparinux is also called factor IIa.
12. Low-molecular-weight heparin (LMWH) is a class of anticoagulant medications. Which is a
characteristic of LMWH?
1. It consists of large fragments of heparin.
2. It binds to plasma proteins as strongly as standard heparin.
3. It can be administered subcutaneously.
4. It has more side effects than standard heparin.
, 13. The nurse is caring for a client who feels tired and weak and reports shortness of breath and pink or
purple spots on the skin. Which treatment does the nurse recognize as the most effective intervention
for this client?
1. Performing plasmapheresis
2. Administering corticosteroid drugs
3. Providing direct thrombin inhibitors
4. Performing factor VIII replacement therapy
14. A client reports abdominal pain, fever, and fatigue. On assessment, the client is diagnosed with
hemolytic-uremic syndrome. Which abnormal diagnostic test result could further confirm the
diagnosis?
1. High proteinuria and hematuria
2. High blood urea nitrogen
3. Low serum creatinine
4. Low bilirubin
15. A client reports unsteadiness, vertigo, dizziness, and seizures. On assessment, the client is diagnosed
with essential thrombocytosis. Which is the abnormal manifestation found during the diagnosis?
1. Decreased bleeding
2. Decreased number of white blood cells (WBCs)
3. Decreased number of platelets
4. Increased number of red blood cells (RBCs)

the client show a body tempNerUaR
