Chapter 33 : Management of Patients With Nonmalignant Hematologic Disorders Questions
Question 1 of 5
A nurse is caring for a patient with severe anemia. The patient is tachycardic and complains of dizziness and exertional dyspnea. The nurse knows that in an effort to deliver more blood to hypoxic tissue, the workload on the heart is increased. What signs and symptoms might develop if this patient goes into heart failure?
Correct Answer: A
Rationale: Cardiac status must be carefully assessed in patients with anemia. When the hemoglobin level is low, the heart attempts to compensate by pumping faster and harder in an effort to deliver more blood to hypoxic tissue. This increased cardiac workload can result in such symptoms as tachycardia, palpitations, dyspnea, dizziness, orthopnea, and exertional dyspnea. Heart failure may eventually develop, as evidenced by an enlarged heart (cardiomegaly) and liver (hepatomegaly), and by peripheral edema. Nausea, migraine, and fever are not associated with heart failure.
Question 2 of 5
A patient is admitted to the diagnosis of pernicious anemia. The nurse should prepare to administer which of the following medications?
Correct Answer: B
Rationale: Pernicious anemia is characterized by vitamin B12 deficiency. Magnesium sulfate, lactulose, and folic acid do not address the pathology of this type of anemia.
Question 3 of 5
A patients blood work reveals a platelet level of 17,000/mm3. When inspecting the patients integumentary system, what finding would be most consistent with this platelet level?
Correct Answer: B
Rationale: When the platelet count drops to less than 20,000/mm?³, petechiae can appear. Low platelet levels do not normally result in dermatitis, urticaria (hives), or alopecia (hair loss).
Question 4 of 5
A nurse is admitting a patient with immune thrombocytopenic purpura to the unit. In completing the admission assessment, the nurse must be alert for what medications that potentially alter platelet function?
Correct Answer: C,D,E
Rationale: The nurse must be alert for sulfa-containing medications and others that alter platelet function (e.g., aspirin-based or other NSAIDs). Antihypertensive drugs and the penicillins do not alter platelet function.
Question 5 of 5
A patient, 25 years of age, comes to the emergency department complaining of excessive bleeding from a cut sustained when cleaning a knife. Blood work shows a prolonged PT but a vitamin K deficiency is ruled out. When assessing the patient, areas of ecchymosis are noted on other areas of the body. Which of the following is the most plausible cause of the patients signs and symptoms?
Correct Answer: D
Rationale: Prolongation of the PT, unless it is caused by vitamin K deficiency, may indicate severe hepatic dysfunction. The majority of hemophiliacs are diagnosed as children. The scenario does not describe signs or symptoms of lymphoma or leukemia.
