A nurse is educating a group of clients with hemophilia about diagnostic evaluation.
Which tests are typically used to diagnose hemophilia?
Genetic testing for the F8 or F9 gene mutations.
Prothrombin time (PT)
Partial thromboplastin time (PTT)
Platelet count.
Fibrinogen levels.
Correct Answer : A,C,E
Choice A rationale:
Genetic testing for the F8 or F9 gene mutations.
Rationale: Genetic testing for mutations in the F8 (Factor VIII) or F9 (Factor IX) genes is a critical diagnostic evaluation for hemophilia.
Hemophilia A is caused by mutations in the F8 gene, while hemophilia B is caused by mutations in the F9 gene.
Choice B rationale:
Prothrombin time (PT)
Rationale: PT is not typically used to diagnose hemophilia.
It primarily evaluates the extrinsic and common coagulation pathways, which are not directly related to hemophilia, which is a disorder of the intrinsic coagulation pathway.
Choice C rationale:
Partial thromboplastin time (PTT)
Rationale: PTT is one of the key tests used to diagnose hemophilia.
It assesses the intrinsic coagulation pathway, and prolonged PTT results may indicate a bleeding disorder, including hemophilia.
Choice D rationale:
Platelet count.
Rationale: Platelet count is not a specific test for diagnosing hemophilia.
Hemophilia is a deficiency in clotting factors, not a platelet disorder.
Platelet counts are typically normal in individuals with hemophilia.
Choice E rationale:
Fibrinogen levels.
Rationale: Fibrinogen levels are not typically used to diagnose hemophilia.
Hemophilia is characterized by deficiencies in specific clotting factors (Factor VIII or Factor IX), and fibrinogen levels are not directly related to these factors.

Related Questions
Correct Answer is A
Explanation
Choice A rationale:
"Can you describe the triggers for your bleeding episodes?”
This is the correct choice.
Understanding the triggers for bleeding episodes can help determine the type and severity of hemophilia.
For example, frequent spontaneous bleeding without apparent triggers may suggest severe hemophilia, while bleeding triggered by trauma or surgery may indicate a milder form.
Choice B rationale:
"What is the frequency of your joint pain?”
This choice is relevant to assessing the impact of hemophilia on the patient's quality of life but does not directly help determine the type and severity of hemophilia.
Choice C rationale:
"Do you have a family history of hemophilia?”
While family history is important in assessing the risk of hemophilia, it alone does not provide information about the type and severity of the patient's condition.
Choice D rationale:
"Have you been prescribed antifibrinolytic agents?”
This question pertains to treatment rather than the assessment of the type and severity of hemophilia.
It is important to know the treatment history but does not provide direct insight into the condition's severity.
Correct Answer is ["A","C","D"]
Explanation
Choice A rationale:
The nurse should recommend avoiding invasive procedures and injections for a patient with hemophilia.
Hemophilia is a bleeding disorder characterized by a deficiency in clotting factors, and any invasive procedures or injections can lead to bleeding episodes.
This recommendation is essential to prevent unnecessary bleeding and complications.
Choice B rationale:
The use of nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief is not a suitable recommendation for a patient with hemophilia.
NSAIDs can increase the risk of bleeding due to their antiplatelet effects.
It is crucial to avoid medications that can worsen bleeding in individuals with hemophilia.
Choice C rationale:
Engaging in gentle exercise to maintain joint function is a valuable recommendation for patients with hemophilia.
Hemophilia often leads to joint problems due to repeated bleeding episodes, and gentle exercise can help maintain joint mobility and prevent contractures.
It is essential to recommend exercise within the patient's tolerance to promote joint health.
Choice D rationale:
Monitoring for signs of anemia and thrombosis is important for patients with hemophilia.
Anemia can occur if there is excessive bleeding, leading to a decrease in red blood cell count.
Additionally, patients with hemophilia are at risk of developing thrombosis due to treatment with clotting factor concentrates.
Therefore, regular monitoring for these complications is necessary to ensure timely intervention if needed.
Choice E rationale:
Applying heat to bleeding joints to alleviate pain is not a recommended practice for patients with hemophilia.
Heat can increase blood flow to the affected area, potentially exacerbating bleeding.
Cold therapy, such as ice packs, is often recommended to reduce inflammation and pain while minimizing the risk of bleeding.
