A client with hemophilia has prolonged partial thromboplastin time (PTT) and normal prothrombin time (PT)
What does this laboratory result indicate about the client's condition?
The client has a normal coagulation profile.
The client may have a vitamin K deficiency.
The client likely has hemophilia.
The client is at risk for thrombosis.
The Correct Answer is C
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 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 C
Explanation
Choice A rationale:
Hypertension is not a common complication of hemophilia.
While bleeding disorders like hemophilia can lead to bleeding in various body systems, hypertension is not directly associated with hemophilia.
Therefore, it is not a priority in the care plan for a client with hemophilia.
Choice B rationale:
Deep vein thrombosis (DVT) is a condition characterized by the formation of blood clots in deep veins, which can lead to serious complications.
While individuals with hemophilia are at an increased risk of bleeding, they are not at an increased risk of DVT.
In fact, individuals with hemophilia often have difficulty forming blood clots, making DVT less likely in this population.
Therefore, it is not a priority in the care plan for a client with hemophilia.
Choice D rationale:
Hyperlipidemia refers to high levels of lipids (fats) in the blood, such as cholesterol and triglycerides.
It is not a common complication of hemophilia, and there is no direct link between hemophilia and hyperlipidemia.
Therefore, it is not a priority in the care plan for a client with hemophilia.
Choice C rationale:
Hemarthrosis is a critical complication that should be prioritized in the care plan for a client with hemophilia.
Hemarthrosis is the bleeding into joint spaces, which can lead to severe pain, swelling, and reduced range of motion in the affected joint.
It is a common and serious complication in individuals with hemophilia because bleeding into joints can cause long-term damage and disability.
Therefore, the nurse should prioritize assessing and managing hemarthrosis in the client's care plan to prevent further complications.
