A nurse is collecting data from a patient who has dehydration. Which of the following findings should the nurse expect?
Moist skin
Dark-colored urine
High blood pressure
Distended neck veins
The Correct Answer is B
Choice A reason: Moist skin is not a sign of dehydration, but rather a sign of adequate hydration or sweating. Dehydration can cause dry skin, mucous membranes, and lips.
Choice B reason: Dark-colored urine is a sign of dehydration, as it indicates a high concentration of waste products and a low volume of water in the urine. Dehydration can cause the kidneys to conserve water and produce less urine.
Choice C reason: High blood pressure is not a sign of dehydration, but rather a sign of fluid overload or other factors such as stress, pain, or medication. Dehydration can cause low blood pressure, as it reduces the blood volume and the cardiac output.
Choice D reason: Distended neck veins are not a sign of dehydration, but rather a sign of fluid overload or right-sided heart failure. Dehydration can cause flat neck veins, as it reduces the venous return and the central venous pressure.

Correct Answer is A
Explanation
Choice A reason: This is correct because metabolic alkalosis is characterized by a high pH and a high HCO3-. The client's pH and HCO3- are both high, indicating a metabolic disorder. The condition is uncompensated because the PaCO2 is normal, meaning the respiratory system is not compensating for the metabolic alkalosis.
Choice B reason: This is incorrect because metabolic acidosis is characterized by a low pH and a low HCO3-. The client's pH and HCO3- are both high, indicating alkalosis, not acidosis.
Choice C reason: This is incorrect because respiratory alkalosis is characterized by a high pH and a low PaCO2. The client's pH is high, but PaCO2 is normal, indicating a metabolic problem, not a respiratory one.
Choice D reason: This is incorrect because respiratory acidosis is characterized by a low pH and a high PaCO2. The client's pH is high, and PaCO2 is normal, indicating a metabolic problem, not a respiratory one.
Correct Answer is A
Explanation
Choice A reason: This is correct because an electrolyte is a substance that dissociates into ions when dissolved in water, and can conduct electricity. Some examples of electrolytes in the body are sodium, potassium, calcium, chloride, and bicarbonate.
Choice B reason: This is incorrect because an electrolyte is not a solid or a gas, but a dissolved substance. Electrolytes are essential for maintaining fluid balance, nerve impulses, muscle contractions, and acid-base balance in the body.
