Which of the following is a characteristic finding in progeria?
High levels of hyaluronic acid
Low levels of glutamate
High levels of thyroxine
Low levels of calcitonin
The Correct Answer is A
A. Progeria, also known as Hutchinson-Gilford Progeria Syndrome (HGPS), is characterized by accelerated aging. One of the biochemical changes observed in this condition is an increase in hyaluronic acid levels, which is associated with skin changes and the premature aging process seen in affected individuals.
B. Low levels of glutamate are not characteristic of progeria. Glutamate is a neurotransmitter, and its levels are not typically altered in progeria.
C. High levels of thyroxine are not associated with progeria. Thyroxine levels are related to thyroid function, and there is no direct link between high thyroxine levels and progeria.
D. Low levels of calcitonin are not characteristic of progeria. Calcitonin is a hormone involved in calcium regulation, and its levels are not notably altered in progeria.

Correct Answer is B
Explanation
A. Adjusting thirst sensation is not the primary focus of treatment for Diabetes Insipidus. The condition is more concerned with fluid balance and preventing dehydration due to excessive urination.
B. Hydration is crucial in the management of Diabetes Insipidus, as patients experience excessive urination and fluid loss. Proper hydration helps prevent dehydration and its associated complications.
C. A 24-hour urine collection is used to assess the extent of polyuria but is not a primary treatment strategy. Treatment focuses on managing fluid balance rather than just monitoring urine output.
D. While increasing Antidiuretic Hormone (ADH) or using synthetic ADH (desmopressin) can be part of treatment, the key treatment focus is maintaining adequate hydration to counteract the effects of polyuria.
Correct Answer is D
Explanation
A. Dark-colored urine is typically a sign of dehydration, as the kidneys concentrate the urine when the body is low on water. Adequate hydration usually results in lighter-colored urine.
B. Strong-smelling urine can indicate dehydration, certain foods, or medications, but it is not an indicator of adequate hydration. Properly hydrated urine typically has a mild odor.
C. Oliguria, or low urine output, can be a sign of dehydration, kidney dysfunction, or other underlying issues. It is not a sign of adequate hydration.
D. Pale-colored urine is a characteristic of adequate hydration. When the body is well-hydrated, the kidneys excrete a greater volume of diluted urine, which tends to be light in color.
