A client with thrombocytopenia experiences prolonged bleeding even after minor trauma.
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.”

"A platelet count below 50,000/uL can result in prolonged bleeding.”

"Platelet count has no impact on bleeding risk.”

"Bleeding risk increases with a platelet count above 150,000/uL.”

Answer and Explanation

The Correct Answer is B

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)

Correct Answer is B

Explanation

Choice A rationale:

"Increased platelet production due to chemotherapy." Rationale: This statement is not accurate.

Chemotherapy often suppresses bone marrow function, leading to a decrease in platelet production, not an increase.

Thrombocytopenia is a common side effect of chemotherapy due to reduced platelet production.

Choice B rationale:

"Immune-mediated platelet destruction caused by chemotherapy." Rationale: This statement is correct.

Thrombocytopenia in patients undergoing chemotherapy is often due to immune-mediated platelet destruction.

Chemotherapy can trigger an autoimmune response, leading to the destruction of platelets by the immune system.

Choice C rationale:

"Thrombocytopenia in this case is unrelated to chemotherapy." Rationale: This statement is unlikely to be true.

Thrombocytopenia occurring in a patient following chemotherapy is often directly related to the treatment.

While other factors may contribute, chemotherapy is a known cause of decreased platelet counts.

Choice D rationale:

"Thrombocytopenia results from the inhibition of platelet aggregation by chemotherapy." Rationale: This statement is not accurate.

Chemotherapy primarily affects platelet production and can lead to a decrease in platelet count.

It does not typically inhibit platelet aggregation.

A. Administer platelet transfusion. B. Encourage high-intensity physical activity. C. Monitor for signs of bleeding. D. Administer heparin therapy. E. Educate the patient on infection prevention.

Correct Answer is ["A","C","E"]

Explanation

Choice A rationale:

"Administer platelet transfusion." Rationale: This is an appropriate intervention for a patient with thrombocytopenia, especially if they are experiencing severe bleeding or have a very low platelet count.

Platelet transfusion can help increase the platelet count and prevent or stop bleeding.

Choice B rationale:

"Encourage high-intensity physical activity." Rationale: This intervention is not appropriate for a patient with thrombocytopenia.

High-intensity physical activity can increase the risk of bleeding in these patients due to the low platelet count.

Choice C rationale:

"Monitor for signs of bleeding." Rationale: This is an essential intervention for a patient with thrombocytopenia.

Monitoring for signs of bleeding, such as petechiae, ecchymosis, or mucosal bleeding, allows for early detection and intervention.

Choice D rationale:

"Administer heparin therapy." Rationale: This intervention is not appropriate for a patient with thrombocytopenia, especially if the thrombocytopenia is immune-mediated, as heparin can exacerbate the condition.

Choice E rationale:

"Educate the patient on infection prevention." Rationale: This is an appropriate intervention for a patient with thrombocytopenia.

Patients with low platelet counts are at increased risk of infection, so education on infection prevention measures, such as hand hygiene and avoiding sick individuals, is essential.
