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.

Explanation
Uremia is a condition where there is an excess of urea and other nitrogenous wastes in the blood, usually excreted by the kidneys into the urine. It occurs when the kidneys stop filtering toxins out through your urine and can be a sign of end-stage renal (kidney) disease.
Choice A is wrong because azotemia is the buildup of nitrogen waste products in the blood, not urea.
Choice C is wrong because anuria is the absence or reduction of urine output.
Choice D is wrong because oliguria is the low output of urine.
Correct Answer is A
Explanation
Metabolic acidosis is a condition in which there is excess acid in the body fluids.
It causes rapid breathing, confusion, tiredness, headache, and increased heart rate.
Rapid breathing is a compensatory mechanism that helps to lower the carbon dioxide levels and increase the pH of the blood.
Choice B is wrong because decreased respiratory rate would worsen the acidosis by retaining more carbon dioxide and lowering the pH of the blood.
Choice C is wrong because normal respiratory rate would not be adequate to compensate for the metabolic acidosis and would result in acidemia (low blood pH).
Choice D is wrong because irregular respiratory rate is not a typical response to metabolic acidosis and could indicate other problems such as brain injury or drug overdose.
