Chapter 32 : Assessment of Hematologic Function and Treatment Modalities Questions
Question 1 of 5
The nurses review of a patients most recent blood work reveals a significant increase in the number of band cells. The nurses subsequent assessment should focus on which of the following?
Correct Answer: C
Rationale: Ordinarily, band cells account for only a small percentage of circulating granulocytes, although their percentage can increase greatly under conditions in which neutrophil production increases, such as infection. This finding is not suggestive of problems with oxygenation and subsequent activity intolerance.
Question 2 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 3 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 4 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 5 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.
