Which of the following would be the best indicator of adequate hydration?
Increased urine output.
Decreased urine output.
Dry mucous membranes.
Hypertension.
The Correct Answer is A
Increased urine output is a sign of adequate hydration, as it means the kidneys are filtering waste and fluids from the body through the urine. The urine should be pale straw or lemonade colored, which indicates good hydration.
Choice B is wrong because decreased urine output is a sign of dehydration, as it means the kidneys are not working well and waste products are accumulating in the blood.
The urine may be dark and strong smelling, which indicates poor hydration.
Choice C is wrong because dry mucous membranes are a sign of dehydration, as they indicate a lack of fluid in the body tissues.
Choice D is wrong because hypertension is not a direct indicator of hydration status, although dehydration can cause low BP due to reduced blood volume.

Correct Answer is A
Explanation
The correct answer is choice A. Daily weight.
According to MDCalc, daily weight is the most accurate indicator of fluid loss or gain in acutely ill patients, as it reflects changes in total body water.
A weight change of 1 kg corresponds to a fluid change of approximately 1 L.
Choice B is wrong because intake and output measurements can be inaccurate or incomplete, and do not account for insensible fluid losses.
Choice C is wrong because serum osmolality reflects the concentration of solutes in the blood, not the volume of fluid.
Choice D is wrong because urine specific gravity reflects the concentration of solutes in the urine, not the volume of fluid.
Correct Answer is B
Explanation
This is because hyponatremia is a condition where sodium levels in your blood are lower than normal, usually due to too much water in your body that dilutes the sodium. A hypertonic saline solution is a fluid that has a higher concentration of sodium than blood, and it can help restore the normal sodium balance by drawing water out of the cells.
Choice A is wrong because restricting fluid intake may not be enough to correct severe hyponatremia, and it may worsen the symptoms of dehydration.
Choice C is wrong because encouraging increased fluid intake will further lower the sodium levels and increase the risk of complications such as brain swelling.
Choice D is wrong because administering a loop diuretic will cause more sodium and water loss from the kidneys, which can worsen hyponatremia and dehydration.
Normal ranges for blood sodium levels are between 135 and 145 milliequivalents per liter (mEq/L).
Hyponatremia is defined as a blood sodium level below 135 mEq/L1.
