Which statement is true regarding hemophilia?
Hemophilia is not hereditary in nature.
Hemophilia can be treated by replacement therapy.
Hemophilia is an X-linked dominant genetic disorder.
Hemophilia B is the most common form of hemophilia.
The Correct Answer is B
Choice A rationale:
Hemophilia is a hereditary disorder caused by a deficiency of specific clotting factors, and it is indeed hereditary in nature. This statement is incorrect.
Choice B rationale:
Hemophilia is a bleeding disorder where the blood does not clot properly. Replacement therapy, which involves infusing clotting factor concentrates, is a standard treatment for hemophilia. This statement is correct.
Choice C rationale:
Hemophilia is an X-linked recessive genetic disorder, not dominant. Males are more commonly affected because they have only one X chromosome, and if it carries the defective gene, they will have hemophilia. Females have two X chromosomes, and if one X chromosome carries the defective gene, the other X chromosome can compensate, making them carriers but not typically affected.
Choice D rationale:
Hemophilia A is the most common form of hemophilia, not hemophilia B.

Correct Answer is B
Explanation
Choice A rationale:
Skeletal pain is not a typical finding in stage I Hodgkin lymphoma. Hodgkin lymphoma typically presents with painless enlarged lymph nodes, which is a hallmark symptom of the disease.
Choice B rationale:
Enlarged lymph nodes are a characteristic feature of Hodgkin lymphoma. In stage I, the disease is localized to one group of lymph nodes.
Choice C rationale:
T-cell blasts in the lymph node are not specific to Hodgkin lymphoma. Hodgkin lymphoma is characterized by the presence of Reed-Sternberg cells, which are large abnormal B cells, not T-cell blasts.
Choice D rationale:
Lymphoblasts in the cerebrospinal fluid are not associated with Hodgkin lymphoma. Involvement of the central nervous system is rare in Hodgkin lymphoma and typically does not lead to the presence of lymphoblasts in the cerebrospinal fluid.
Correct Answer is D
Explanation
Choice A rationale:
Fullness from ascites is a symptom associated with conditions like liver cirrhosis, not directly related to chronic heart failure. Ascites is the accumulation of fluid in the abdominal cavity, causing a feeling of fullness and abdominal discomfort.
Choice B rationale:
Hypoproteinemia, a condition characterized by low levels of proteins in the blood, can lead to fluid retention and edema. However, it is not a direct cause of frequent urination. Frequent urination in this context is more likely related to increased fluid volume in the body, which can be caused by increased renal perfusion in the supine position due to fluid redistribution from the lower extremities to the kidneys.
Choice C rationale:
Hypoperfusion to the brain can lead to neurological symptoms, but it does not directly cause frequent urination. Frequent urination is often related to the kidneys' ability to filter excess fluid and excrete it as urine.
Choice D rationale:
Increased renal perfusion in the supine position can cause frequent urination, especially at night. When a person with chronic heart failure lies down, fluid that has accumulated in the lower extremities (edema) during the day is redistributed to the kidneys due to the change in body position. This increased renal perfusion results in an increased production of urine, leading to nocturia (frequent urination at night) and disrupting the patient's ability to sleep well. This symptom is characteristic of heart failure-related fluid overload and is an important clinical sign indicating worsening heart failure.
