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:
The client has a normal coagulation profile.
This choice is incorrect because the client's prolonged PTT suggests a problem with the intrinsic pathway of coagulation, which is typical in hemophilia.
A normal coagulation profile would show normal values for both PTT and PT.
Choice B rationale:
The client may have a vitamin K deficiency.
This choice is not applicable in this context.
A vitamin K deficiency primarily affects the extrinsic pathway of coagulation, leading to an elevated PT, but it does not typically affect the PTT, which is prolonged in hemophilia.
Choice C rationale:
The client likely has hemophilia.
This is the correct choice.
Hemophilia is characterized by a deficiency or dysfunction of clotting factors, most commonly factor VIII (hemophilia A) or factor IX (hemophilia B)
Prolonged PTT with normal PT is a classic laboratory finding in hemophilia.
Choice D rationale:
The client is at risk for thrombosis.
This choice is incorrect.
Hemophilia is associated with bleeding tendencies, not an increased risk of thrombosis.
Prolonged PTT indicates a reduced ability to form clots, making thrombosis less likely.
Correct Answer is B
Explanation
"Apply pressure, ice, and compression to the affected joint."
Choice A rationale:
"Administer acetaminophen as prescribed." While pain management is essential for clients with hemophilia, acetaminophen is not the first-line choice because it does not have anti-inflammatory properties.
Additionally, in hemophilia, there is a risk of liver damage from excessive acetaminophen use.
Choice B rationale:
"Apply pressure, ice, and compression to the affected joint." This is the correct choice.
Applying ice and compression to the affected joint can help reduce pain and inflammation in clients with hemophilia.
It is a safe and effective nursing intervention.
Choice C rationale:
"Refer the client to genetic counseling services." Genetic counseling is important in hemophilia for family planning and risk assessment.
However, it is not the priority nursing intervention for managing acute joint pain.
Choice D rationale:
"Encourage the client to perform vigorous physical exercises." Encouraging vigorous physical exercises is not advisable for clients with hemophilia, especially when they are experiencing joint pain.
It can increase the risk of bleeding and further joint damage.
