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.

Answer and Explanation

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.

A. pH = 7.46, PaCO2 = 44 mm Hg, PaO2 = 95 mm Hg, and HCO3 = 36 mEq/L. B. pH = 7.27, PaCO2 = 70 mm Hg, PaO2 = 80 mm Hg, and HCO3 = 26 mEq/L. C. pH = 7.30, PaCO2 = 35 mm Hg, PaO2 = 70 mm Hg, and HCO3 = 20 mEq/L. D. pH = 7.52, PaCO2 = 24 mm Hg, PaO2 = 85 mm Hg, and HCO3 = 24 mEq/L.

Correct Answer is D

Explanation

The correct answer is choice d. pH = 7.52, PaCO2 = 24 mm Hg, PaO2 = 85 mm Hg, and HCO3 = 24 mEq/L.

Rationales:

Choice A rationale:

pH = 7.46: This value is slightly alkalotic.
PaCO2 = 44 mm Hg: This is within the normal range (35-45 mm Hg), indicating that the respiratory system is not contributing to alkalosis.
PaO2 = 95 mm Hg: This is a normal oxygen level.
HCO3 = 36 mEq/L: This is elevated, indicating metabolic alkalosis rather than respiratory alkalosis.

Choice B rationale:

pH = 7.27: This value is acidic, indicating acidosis.
PaCO2 = 70 mm Hg: This is elevated, indicating respiratory acidosis.
PaO2 = 80 mm Hg: This is slightly low, indicating mild hypoxemia.
HCO3 = 26 mEq/L: This is within the normal range, indicating no metabolic compensation.

Choice C rationale:

pH = 7.30: This value is acidic, indicating acidosis.
PaCO2 = 35 mm Hg: This is within the normal range, indicating that the respiratory system is not contributing to acidosis.
PaO2 = 70 mm Hg: This is low, indicating hypoxemia.
HCO3 = 20 mEq/L: This is low, indicating metabolic acidosis.

Choice D rationale:

pH = 7.52: This value is alkalotic.
PaCO2 = 24 mm Hg: This is low, indicating respiratory alkalosis.
PaO2 = 85 mm Hg: This is a normal oxygen level.
HCO3 = 24 mEq/L: This is within the normal range, indicating no metabolic compensation.

Choice D corresponds with respiratory alkalosis because the pH is alkalotic, and the PaCO2 is low, indicating that the respiratory system is causing the alkalosis. The HCO3 is within the normal range, showing no metabolic compensation.
