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 D
Explanation
Choice A reason: This is incorrect because the adrenal gland is not involved in the thirst mechanism. The adrenal gland is responsible for producing hormones such as cortisol, aldosterone, and adrenaline, which regulate stress response, blood pressure, and metabolism.
Choice B reason: This is incorrect because the cerebral cortex is not involved in the thirst mechanism. The cerebral cortex is the outer layer of the brain that is responsible for higher cognitive functions such as memory, language, and reasoning.
Choice C reason: This is incorrect because the pituitary gland is not directly involved in the thirst mechanism. The pituitary gland is a small gland at the base of the brain that produces hormones that control growth, reproduction, and metabolism. However, the pituitary gland does secrete antidiuretic hormone (ADH), which is regulated by the hypothalamus and affects water balance in the body.
Choice D reason: This is correct because the hypothalamus is the location of the thirst mechanism. The hypothalamus is a part of the brain that regulates many bodily functions such as temperature, appetite, sleep, and emotions. The hypothalamus also monitors the blood osmolarity and triggers the sensation of thirst when the blood is too concentrated.
Correct Answer is C
Explanation
Choice A reason: This is a low value for serum calcium, which indicates hypocalcemia. Hypocalcemia can cause muscle spasms, tetany, seizures, and cardiac arrhythmias.
Choice B reason: This is also a low value for serum calcium, which indicates hypocalcemia. Hypocalcemia can cause muscle spasms, tetany, seizures, and cardiac arrhythmias.
Choice C reason: This is the normal range of serum calcium in adults. Calcium is essential for bone health, muscle contraction, nerve transmission, and blood clotting.
Choice D reason: This is a high value for serum calcium, which indicates hypercalcemia. Hypercalcemia can cause nausea, vomiting, constipation, confusion, lethargy, and kidney stones.
