- A.
DECREASE
- B.
INCREASE
- C.
NO CHANGE
Correct Answer
B. INCREASEExplanation
Diabetes insipidus is a condition characterized by excessive thirst and urination. It is caused by a deficiency of antidiuretic hormone (ADH) or a resistance to its effects. ADH helps regulate water balance in the body by reducing urine output. In diabetes insipidus, the lack of ADH leads to an increase in urine output, resulting in excessive urination. This is opposite to hypovolemia, which is a condition characterized by low blood volume. In hypovolemia, the body tries to conserve water by reducing urine output. Therefore, the correct answer is "increase" because diabetes insipidus causes an increase in urine output.Rate this question:

- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Diabetes insipidus is a condition characterized by the inability of the body to properly regulate fluid balance, leading to excessive urination and thirst. In this condition, the levels of a hormone called antidiuretic hormone (ADH) are decreased, which results in decreased water reabsorption by the kidneys. As a result, the levels of sodium (Na) in the blood increase. Therefore, it is true that Na levels increase with diabetes insipidus.Rate this question:

SIADH CAN LEAD TO WATER INTOXICATION
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
SIADH (syndrome of inappropriate antidiuretic hormone) is a condition where the body produces too much antidiuretic hormone (ADH), leading to the kidneys retaining more water. This excess water retention can result in dilution of electrolytes in the body, including sodium, which is essential for proper functioning of cells. If the sodium levels become too low, it can cause a condition called water intoxication or hyponatremia. Therefore, it is true that SIADH can lead to water intoxication.Rate this question:

A. FLUID RESTRICTION
B. HYPERTONIC IVExplanation
SIADH (Syndrome of Inappropriate Antidiuretic Hormone) is a condition characterized by excessive release of antidiuretic hormone (ADH), leading to water retention and dilutional hyponatremia. The management of SIADH involves fluid restriction to prevent further water retention and hyponatremia. Hypertonic IV (intravenous) fluids may also be administered to correct hyponatremia by increasing the concentration of sodium in the blood. Therefore, fluid restriction and hypertonic IV are both appropriate management strategies for SIADH. Increased fluids and hypotonic IV would worsen the condition by further diluting the blood sodium levels, so they are not suitable management options for SIADH.Rate this question:

The statement is true because in primary hypothyroid states, the thyroid gland is not able to produce enough thyroid hormones. This leads to an increase in the production of thyroid-stimulating hormone (TSH) by the pituitary gland in an attempt to stimulate the thyroid gland to produce more hormones. Therefore, elevated levels of TSH are commonly seen in primary hypothyroidism.Rate this question:
