The Hematologic System ATI Questions
Question 1 of 5
A client is having a radioisotopic imaging scan. What action by the nurse is most important?
Correct Answer: D
Rationale: The correct answer is D because educating the client about the procedure is crucial for informed consent, reducing anxiety, and promoting cooperation during the scan. This empowers the client to understand what to expect and how to prepare. Assessing for shellfish allergies (A) is not directly related to the scan. Placing the client on radiation precautions (B) is unnecessary as the exposure is minimal, and sedating the client (C) should only be considered if medically indicated, not as a routine practice.
Question 2 of 5
A patient is suffered from vitamin K deficiency. Which of the coagulation factors will not be affected?
Correct Answer: C
Rationale: The correct answer is C: Factor VIII. Factor VIII is not dependent on vitamin K for its synthesis, so its levels will not be affected by vitamin K deficiency. Factor II, VII, and IX are all vitamin K-dependent factors, so their levels will decrease with vitamin K deficiency, leading to impaired blood clotting. This is due to the role of vitamin K in the post-translational modification of these factors, which is necessary for their activation. Therefore, Factor VIII is the only factor that will not be affected by vitamin K deficiency.
Question 3 of 5
Which of the following is not the criteria in the international prognostic index for non Hodgkin's lymphoma?
Correct Answer: C
Rationale: The correct answer is C: Lymphocyte count. In the International Prognostic Index for Non Hodgkin's Lymphoma, the criteria are based on the number of extranodal sites, LDH level, and performance status. Lymphocyte count is not included in the IPI criteria because it does not play a significant role in predicting the prognosis of Non Hodgkin's Lymphoma. Lymphocyte count is not a commonly used parameter in prognostic scoring systems for this type of cancer. Therefore, the absence of lymphocyte count as a criteria in the IPI is justified.
Question 4 of 5
A patient who is infected with hookworms produces signs and symptoms of anemia. Which of the following can be seen in the peripheral blood smear of the patient?
Correct Answer: B
Rationale: The correct answer is B: Basophilic stippling. Hookworm infection can lead to anemia due to chronic blood loss. Basophilic stippling is a characteristic finding in the peripheral blood smear of patients with iron deficiency anemia, which can result from hookworm infection. Basophilic stippling represents the aggregation of ribosomes and is seen in erythrocytes that contain denatured ribosomal RNA. Howell-Jolly bodies are remnants of nuclear material and are typically seen in patients with functional asplenia. Target cells are seen in conditions like liver disease or hemoglobinopathies. Spherocytes are seen in immune hemolytic anemias.
Question 5 of 5
A 50-year-old male who had frequent infections of his upper respiratory tract manifested with subcutaneous petechiae over his arms and legs. Investigations revealed low hemoglobin and a dry tap marrow. The most likely condition the patient is suffering from
Correct Answer: D
Rationale: The correct answer is D: Aplastic anemia. Aplastic anemia is characterized by pancytopenia, which includes low hemoglobin levels leading to anemia. The dry tap marrow indicates bone marrow failure, which is a hallmark of aplastic anemia. The subcutaneous petechiae are due to thrombocytopenia, another feature of this condition. Iron deficiency anemia (A) typically presents with microcytic hypochromic red blood cells and is not associated with bone marrow failure. Megaloblastic anemia (B) is characterized by macrocytic red blood cells and is usually due to deficiencies in vitamin B12 or folate. Hemolytic anemia (C) involves the premature destruction of red blood cells and is not typically associated with bone marrow failure.
