Question 1

Which is circulated by the hematologic system?&#10;A) Oxygen&#10;B) Pathogens&#10;C) Coagulation&#10;D) Temperature&#10;

Accepted Answer

Oxygen is circulated by the hematologic system through the red blood cells, which contain hemoglobin that binds with oxygen in the lungs and delivers it to the various tissues and organs of the body.

Question 2

Which drug prescription should the nurse anticipate to prevent the formation of clots for a patient diagnosed with deep vein thrombosis (DVT)?&#10;A) Warfarin&#10;B) Vitamin K&#10;C) Abciximab&#10;D) Streptokinase&#10;

Accepted Answer

Warfarin, an anticoagulant medication, is commonly used to prevent the formation of clots in patients diagnosed with DVT. Vitamin K is used to reverse the effects of warfarin if necessary. Abciximab and streptokinase are thrombolytic medications used to treat existing clots but are not typically used for prevention.

Question 3

Which is a component of plasma within the blood?&#10;A) Platelets&#10;B) Electrolytes&#10;C) Red blood cells&#10;D) White blood cells&#10;

Accepted Answer

Electrolytes, such as sodium and potassium, are components of plasma within the blood. Platelets, red blood cells, and white blood cells are cellular components of blood.

Question 4

Which laboratory test should the nurse anticipate when providing care to a patient with a clotting disorder caused by the intrinsic pathway?&#10;A) Prothrombin time (PT)&#10;B) Basic metabolic panel (BMP)&#10;C) Complete blood cell (CBC)count&#10;D) Partial thromboplastin time (PTT)&#10;

Accepted Answer

Partial thromboplastin time (PTT) is a laboratory test that measures the time it takes for a clot to form in the intrinsic pathway of the coagulation system. This test is used to diagnose clotting disorders caused by deficiencies in factors in the intrinsic pathway. A prolonged PTT can indicate a clotting disorder caused by the intrinsic pathway.

Question 5

The nurse is providing care to a patient who has impaired platelet aggregation.What does the nurse anticipate based on this data?&#10;A) The patient is taking vitamin K supplements.&#10;B) The patient is taking anti-inflammatory agents.&#10;C) The patient has white blood cell count 4700 cells/microliter.&#10;D) The patient has red blood cell count 4.6 million cells/microliter.&#10;

Accepted Answer

Impaired platelet aggregation can be caused by anti-inflammatory agents, such as aspirin or ibuprofen, which inhibit the formation of thromboxane A2 and impair platelet aggregation. Vitamin K supplements are not typically associated with impaired platelet aggregation. The patient's white and red blood cell counts are not relevant to this situation.

Question 6

Which food should the nurse recommend for a patient who is experiencing anemia caused by a deficiency in folic acid?&#10;A) Fish&#10;B) Poultry&#10;C) Citrus fruits&#10;D) Green leafy vegetables&#10;

Accepted Answer

Green leafy vegetables are a good source of folic acid.

Question 7

Which term should the nurse use when documenting a decreased red blood cell (RBC)count?&#10;A) Anemia&#10;B) Neutropenia&#10;C) Polycythemia&#10;D) Thrombocytopenia&#10;

Accepted Answer

A decreased RBC count is indicative of anemia.

Question 8

Which drug prescription should the nurse anticipate for a patient who presents in the emergency department with symptoms of a thrombotic stroke?&#10;A) Warfarin&#10;B) Vitamin K&#10;C) Abciximab&#10;D) Streptokinase&#10;

Accepted Answer

Streptokinase is a thrombolytic agent used to dissolve blood clots in patients with thrombotic stroke.

Question 9

The nurse is reviewing the complete blood cell (CBC)count for a patient recently admitted to the medical-surgical unit.The CBC count is as follows: platelet 180,000/mm;hemoglobin 15 g/dL;red blood cells - 4.4 $\times$ 10¹²cells/L;white blood cells - 6,000/mm³.Which conclusion by the nurse is appropriate?

A) The patient is anemic.
B) The patient has leukopenia.
C) The patient has thrombocytopenia.
D) The patient's laboratory values are within normal limits.

Accepted Answer

The patient's laboratory values for platelets, hemoglobin, red and white blood cells are all within normal ranges, indicating that the patient does not have thrombocytopenia or leukopenia, and is not anemic. Therefore, the appropriate conclusion is that the patient's laboratory values are within normal limits.

Question 10

Which term should the nurse use when documenting an elevated red blood cell (RBC)count?&#10;A) Anemia&#10;B) Neutropenia&#10;C) Polycythemia&#10;D) Thrombocytopenia&#10;

Accepted Answer

An elevated RBC count is indicative of polycythemia. Anemia is a decrease in RBC count, neutropenia is a decrease in neutrophils, and thrombocytopenia is a decrease in platelets.

Question 11

Which is an age-related hematologic change the nurse anticipates when reviewing a complete blood count (CBC)for an older adult patient?&#10;A) Increased hematocrit&#10;B) Increased hemoglobin&#10;C) Increased B- and T-cells&#10;D) Increased sedimentation rate&#10;
