Chapter 32 : Assessment of Hematologic Function and Treatment Modalities Questions
Question 1 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 2 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 3 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 4 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.
Question 5 of 5
A patients diagnosis of atrial fibrillation has prompted the primary care provider to prescribe warfarin (Coumadin), an anticoagulant. When assessing the therapeutic response to this medication, what is the nurses most appropriate action?
Correct Answer: D
Rationale: The INR and aPTT serve as useful screening tools for evaluating a patients clotting ability and to monitor the therapeutic effectiveness of anticoagulant medications. The patients platelet level is not normally used as a short-term indicator of anticoagulation effectiveness. Assessing the patient for signs of myelosuppression and capillary refill time does not address the effectiveness of anticoagulants.
