Which of the following statements is not a typical manifestation of SIADH?
Anorexia
Edema of fluid overload
Vomiting
Nausea
The Correct Answer is B
A. Anorexia is a common manifestation of SIADH due to the effects of hyponatremia (low sodium levels) and fluid retention.
B. Edema of fluid overload is not a typical manifestation of SIADH. While SIADH leads to fluid retention due to excess antidiuretic hormone (ADH), the excess fluid is typically intracellular and does not cause peripheral edema as seen in conditions like heart failure or nephrotic syndrome.
C. Vomiting is a common manifestation of SIADH, often related to the effects of hyponatremia, which can irritate the gastrointestinal system.
D. Nausea is also a common symptom of SIADH due to the imbalance of electrolytes, particularly low sodium levels, which can affect the brain and lead to nausea.

Correct Answer is A
Explanation
A. Desmopressin (DDAVP) is the correct treatment for Diabetes insipidus. This medication is a synthetic form of vasopressin, which helps the kidneys to retain water, thereby reducing the symptoms of excessive urination and thirst in individuals with Diabetes insipidus.
B. Furosemide is a loop diuretic used to treat fluid retention, not Diabetes insipidus. It increases urine output, which would worsen the condition in patients with Diabetes insipidus.
C. Diuretics are used to increase urine output and are not used in the treatment of Diabetes insipidus, as they could exacerbate dehydration.
D. Corticosteroids are not used to treat Diabetes insipidus. They are typically used to treat inflammatory conditions, such as rheumatoid arthritis, but not Diabetes insipidus.
Correct Answer is B
Explanation
A. Both Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) can cause lymph node enlargement in various locations, including the neck. The location of the lymph nodes alone does not differentiate between the two types of lymphoma.
B. The presence of Reed-Sternberg cells is a hallmark of Hodgkin lymphoma. These abnormal cells are typically found in the lymph nodes of patients with HL and are a key diagnostic feature.
C. Hodgkin lymphoma is more common in young adults and older adults, but it can occur at any age. Non-Hodgkin lymphoma has a broader age distribution and can affect individuals of all ages, so age alone is not a distinguishing factor.
D. Both Hodgkin and non-Hodgkin lymphoma can spread to the spleen, liver, and bone marrow, so the spread of disease alone is not specific to either type of lymphoma. The presence of Reed-Sternberg cells is the key diagnostic feature for Hodgkin lymphoma.
