Thrombocytopenia
Thrombocytopenia ( 15 Questions)
What statement by the nurse accurately explains the relationship between platelet count and bleeding risk?
"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.
"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.
"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)
"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)
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)
