What is a common characteristic of diabetes insipidus?

Hyperglycemia

Polydipsia

Weight gain

Oliguria

Answer and Explanation

The Correct Answer is B

A. Hyperglycemia: Hyperglycemia is characteristic of diabetes mellitus, not diabetes insipidus. Diabetes insipidus involves an issue with antidiuretic hormone (ADH) and water balance, not glucose regulation.

B. Polydipsia: This is a hallmark symptom of diabetes insipidus. It refers to excessive thirst due to the body’s inability to retain water, leading to dehydration and compensatory increased fluid intake.

C. Weight gain: Weight gain is not typically associated with diabetes insipidus. The condition usually leads to weight loss due to fluid loss.

D. Oliguria: Oliguria (reduced urine output) is the opposite of what occurs in diabetes insipidus. The condition is characterized by polyuria, or excessive urination, due to the kidneys' inability to concentrate urine.

Correct Answer is A

Explanation

This condition is an inflammation of the pericardium, which is the thin layer of tissue that surrounds and protects the heart. The inflammation can cause fluid to accumulate in the pericardial space, which can compress the heart and impair its function. The symptoms of pericarditis may include chest pain that worsens with breathing or lying down, shortness of breath, fever, chills, sweating, or low blood pressure.
