The nurse is providing care for a client with a diagnosis of otosclerosis due to previous ear surgeries. Which type of pathological hearing loss supports the client's clinical history?

Disseminated intravascular coagulation (DIC) is a serious condition characterized by widespread activation of coagulation throughout the body, leading to both thrombosis and hemorrhage. Here's why option C is the correct choice:

A) Glucosuria and lethargy:

Glucosuria (presence of glucose in the urine) and lethargy are not typical findings associated with DIC. Glucosuria may indicate diabetes mellitus or renal dysfunction, while lethargy can result from various causes but is not specific to DIC.

B) Frothy urine and anorexia:

Frothy urine may indicate proteinuria, which can occur in conditions such as nephrotic syndrome, but it is not a characteristic finding of DIC. Anorexia (loss of appetite) is a nonspecific symptom that can occur in many conditions but is not directly related to DIC.

C) Hematuria and hemoptysis:

Correct. Hematuria (blood in the urine) and hemoptysis (coughing up blood) are common manifestations of DIC. In DIC, widespread activation of the coagulation cascade can lead to microthrombi formation in small blood vessels, resulting in tissue ischemia and bleeding. Hematuria and hemoptysis can occur due to bleeding from the urinary tract or respiratory system, respectively, as a result of DIC-induced coagulopathy.

D) Polyuria and productive cough:

Polyuria (excessive urination) and productive cough (cough with production of sputum) are not specific findings of DIC. Polyuria may occur in conditions such as diabetes mellitus or diuretic use, while productive cough can be seen in respiratory infections or chronic lung diseases but is not directly related to DIC.

A) Deficiency of factors VIII or IX.

Hemophilia is a genetic disorder characterized by deficient or defective clotting factors, specifically factors VIII (hemophilia A) or IX (hemophilia B). These clotting factors are essential for the formation of stable blood clots. Therefore, if hemophilia is present, the deficiency of factors VIII or IX can lead to impaired clot formation and prolonged bleeding.

B) Diminished amount of vitamin K:

Vitamin K deficiency can lead to impaired blood clotting due to inadequate synthesis of clotting factors in the liver. However, hemophilia is specifically associated with deficiencies in factors VIII or IX, not vitamin K.

C) Decreased amount of platelets:

Platelets play a crucial role in primary hemostasis and initial platelet plug formation at the site of vascular injury. While decreased platelet count or dysfunction can lead to bleeding disorders such as thrombocytopenia or platelet function disorders, hemophilia specifically involves deficiencies in clotting factors, not platelets.

D) Missing factors V and VII:

Factor V and VII are other clotting factors involved in the coagulation cascade, but they are not deficient in hemophilia. Hemophilia is specifically characterized by deficiencies in factors VIII (hemophilia A) or IX (hemophilia B).
