A nurse is providing education to a group of parents about hemophilia.
Which statement by one of the parents indicates a need for further teaching?
"Hemophilia A is more common than hemophilia B.”
"Hemophilia is inherited through a defective gene on the Y chromosome.”
"Males inherit hemophilia from their mothers who carry the defective gene.”
"Females can also have hemophilia, but it is very rare.”
The Correct Answer is D
Choice A rationale:
Hemophilia A and hemophilia B are both types of hemophilia, but hemophilia A is actually less common than hemophilia B.
The prevalence of hemophilia A is about 1 in 5,000 males, whereas hemophilia B occurs in about 1 in 25,000 males.
Therefore, this statement is incorrect.
Choice B rationale:
Hemophilia is not inherited through a defective gene on the Y chromosome.
Hemophilia is an X-linked recessive genetic disorder, which means it is caused by a mutation in genes located on the X chromosome, not the Y chromosome.
This statement is incorrect.
Choice C rationale:
This statement is correct.
Males inherit hemophilia from their mothers who carry the defective gene on one of their X chromosomes.
However, it's important to note that females can also be carriers of the gene and can pass it on to their sons.
This statement does not indicate a need for further teaching.
Choice D rationale:
This statement is incorrect.
While it is very rare for females to have hemophilia, it is not impossible.
Females can inherit hemophilia if they have two affected X chromosomes or if they inherit one affected X chromosome and one affected Y chromosome.
Therefore, this statement does not indicate a need for further teaching.

Correct Answer is C
Explanation
Choice A rationale:
Factor replacement therapy, such as the administration of factor VIII concentrates, is the primary treatment for managing bleeding episodes in patients with hemophilia.
However, it does not specifically inhibit the breakdown of fibrin clots, which is the primary role of aminocaproic acid.
Choice B rationale:
Desmopressin acetate (DDAVP) is used to stimulate the release of factor VIII and von Willebrand factor from endothelial cells.
While it can help in some cases, it may not be the most effective choice for mucosal bleeding episodes like epistaxis and oral bleeding, where aminocaproic acid is more commonly used.
Choice C rationale:
Aminocaproic acid is an antifibrinolytic medication that inhibits the breakdown of fibrin clots.
It is particularly useful in managing mucosal bleeding episodes in patients with hemophilia, such as epistaxis and oral bleeding, by preventing the premature dissolution of clots and promoting hemostasis.
Choice D rationale:
Gene therapy is an emerging treatment for hemophilia, but it does not directly address the breakdown of fibrin clots.
It aims to provide a long-term solution by introducing functional clotting factor genes into the patient's body, but it may not be the immediate choice for managing acute bleeding episodes.
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.
