Chapter 32 : Assessment of Hematologic Function and Treatment Modalities Questions
Question 1 of 5
A nurse is educating a patient about the role of B lymphocytes. The nurses description will include which of the following physiologic processes?
Correct Answer: D
Rationale: B lymphocytes are capable of differentiating into plasma cells. Plasma cells, in turn, produce antibodies. Cytokines are produced by NK cells. Stem cell differentiation greatly precedes B lymphocyte production.
Question 2 of 5
A patients most recent blood work reveals low levels of albumin. This assessment finding should suggest the possibility of what nursing diagnosis?
Correct Answer: A
Rationale: Albumin is particularly important for the maintenance of fluid balance within the vascular system. Deficiencies nearly always manifest as fluid imbalances. Tissue oxygenation and skin integrity are not normally affected. Low albumin does not constitute a risk for infection.
Question 3 of 5
An individual has accidentally cut his hand, immediately initiating the process of hemostasis. Following vasoconstriction, what event in the process of hemostasis will take place?
Correct Answer: B
Rationale: Following vasoconstriction, circulating platelets aggregate at the site and adhere to the vessel and to one another, forming an unstable hemostatic plug. Events involved in the clotting cascade take place subsequent to this initial platelet action.
Question 4 of 5
The nurse is providing care for an older adult who has a hematologic disorder. What age-related change in hematologic function should the nurse integrate into care planning?
Correct Answer: B
Rationale: Due to a variety of factors, when an older person needs more blood cells, the bone marrow may not be able to increase production of these cells adequately. Stem cell activity continues throughout the lifespan, although at a somewhat decreased rate. The proportion of functional cells does not greatly decrease and the relative volume of plasma does not change significantly.
Question 5 of 5
A clients health history reveals daily consumption of two to three bottles of wine. The nurse should plan assessments and interventions in light of the patients increased risk for what hematologic disorder?
Correct Answer: B
Rationale: Heavy alcohol use is associated with numerous health problems, including anemia. Leukemia and lymphoma are not associated with alcohol use; RBC levels are typically affected more than platelet levels.
