QUESTIONS (TEST 4, FALL 2024/25) GRADED A+
When caring for a patient with thrombocytopenia, the nurse instructs the patient to:
a. dab his or her nose instead of blowing
b. be careful when shaving with a safety razor
c. continue with physical activities to stimulate thrombopoiesis
d. avoid Aspirin (ASA) because it may mask the fever that occurs with thrombocytopenia - ANSWER A -
Patients with thrombocytopenia should avoid aspirin because it reduces platelet adhesiveness, which
contributes to bleeding. Patients should not perform vigorous exercise or lift weights. If a patient is weak
and at risk for falling, supervise the patient when he or she is out of bed. Blowing the nose forcefully
should be avoided. The patient should gently pat the nose with a tissue if needed. Instruct patients not
to shave with a blade; an electric razor should be used.
The nurse would anticipate that a patient with von Willebrand disease undergoing surgery would be
treated with administration of vWF and:
a. thrombin
b. factor VI
c. factor VII
d. factor VIII - ANSWER D - von Willebrand disease involves deficiency of the von Willebrand coagulation
protein, variable factor VIII deficiencies, and platelet dysfunction. Treatment includes administration of
von Willebrand factor and factor VIII.
DIC is a disorder in which:
a. the coagulation pathway is genetically altered, leading to thrombus formation in all major blood
vessels
b. an underlying disease depletes hemolytic factors in the blood, leading to diffuse thrombotic episodes
and infarcts
c. a disease process stimulates coagulation心脏不仅是一个生理器
processes with resultant thrombosis, as well as depletion of
clotting factors, leading to diffuse clotting and hemorrhage
d. an inherited predisposition causes a deficiency of clotting factors that leads to overstimulation of
coagulation processes in the vasculature - ANSWER C - In disseminated intravascular coagulation (DIC),
the coagulation process is stimulated, with resultant thrombosis and depletion of clotting factors, which
leads to diffuse clotting and hemorrhage. The paradox of this condition is characterized by the profuse
bleeding that results from the depletion of platelets and clotting factors.
