A client with thrombocytopenia presents with schistocytes on the peripheral blood smear.
What does the presence of schistocytes indicate, and how should the nurse interpret this finding?
Schistocytes suggest normal platelet function.
Schistocytes are associated with thrombocytosis.
Schistocytes indicate hemolysis or microangiopathy.
Schistocytes confirm the absence of bleeding risk.
The Correct Answer is C
Choice A rationale:
Schistocytes suggest normal platelet function.
Rationale: This statement is incorrect.
Schistocytes are not related to platelet function.
Schistocytes are fragmented red blood cells, and their presence on a peripheral blood smear suggests mechanical damage to red blood cells, not platelets.
Choice B rationale:
Schistocytes are associated with thrombocytosis.
Rationale: This statement is incorrect.
Schistocytes are not associated with thrombocytosis, which is an elevated platelet count.
They are more commonly associated with conditions involving red blood cell fragmentation, such as hemolysis or microangiopathy.
Choice C rationale:
Schistocytes indicate hemolysis or microangiopathy.
Rationale: This statement is correct.
Schistocytes are fragmented red blood cells, and their presence on a peripheral blood smear is indicative of hemolysis (destruction of red blood cells) or microangiopathy (damage to small blood vessels)
This finding suggests that the patient may have an underlying condition leading to red blood cell destruction, which can be associated with thrombocytopenia.
Choice D rationale:
Schistocytes confirm the absence of bleeding risk.
Rationale: This statement is incorrect.
Schistocytes do not confirm the absence of bleeding risk.
While they are associated with conditions involving red blood cell damage, they do not provide information about the patient's platelet count, which is a more direct factor in bleeding risk.

Correct Answer is B
Explanation
Choice A rationale:
"The platelet count is likely within the normal range." Rationale: This statement is unlikely to be true.
Given that the patient is presenting with mucosal bleeding, including petechiae, purpura, and gingival bleeding, it suggests a potential problem with platelet function.
Platelet counts within the normal range do not typically lead to these bleeding symptoms.
Choice B rationale:
"The platelet count may be below 50,000/uL, indicating a risk of prolonged bleeding." Rationale: This statement is accurate.
The symptoms described (petechiae, purpura, and gingival bleeding) are indicative of thrombocytopenia, where the platelet count is typically below 50,000/uL.
This lower count increases the risk of prolonged bleeding and bruising.
Choice C rationale:
"The platelet count is typically above 100,000/uL in thrombocytopenia." Rationale: This statement is not accurate.
Thrombocytopenia is characterized by a decrease in platelet count, often below 100,000/uL, as seen in choice B.
A platelet count above 100,000/uL is not typical in thrombocytopenia.
Choice D rationale:
"The platelet count does not affect bleeding symptoms." Rationale: This statement is incorrect.
Platelet count plays a significant role in the body's ability to form blood clots and prevent bleeding.
Low platelet counts can lead to bleeding symptoms, as described in the patient's presentation of mucosal bleeding.
Platelet count is indeed relevant in assessing and managing bleeding risk in thrombocytopenia.
Correct Answer is B
Explanation
Choice A rationale:
"A platelet count below 100,000/uL is considered normal." Rationale: This statement is incorrect.
A normal platelet count typically ranges between 150,000 and 450,000/uL.
A platelet count below 100,000/uL is not considered normal and may indicate thrombocytopenia or another underlying issue.
Choice B rationale:
"A platelet count below 50,000/uL can result in prolonged bleeding." Rationale: This statement is correct.
Platelets are essential for normal blood clotting, and a platelet count below 50,000/uL can lead to an increased risk of bleeding, especially after minor trauma.
Severe bleeding risk typically occurs when the platelet count drops below 20,000/uL.
Choice C rationale:
"Platelet count has no impact on bleeding risk." Rationale: This statement is incorrect.
Platelet count directly affects bleeding risk.
A lower platelet count increases the risk of bleeding, while a higher count can lead to an increased risk of clot formation (thrombosis)
Choice D rationale:
"Bleeding risk increases with a platelet count above 150,000/uL." Rationale: This statement is incorrect.
A platelet count above 150,000/uL is within the normal range and does not increase the risk of bleeding.
Instead, it may increase the risk of thrombosis (excessive clotting)
