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 {"dropdown-group-1":"A"}
Explanation
Choice A reason: Diffusion is the process by which small ions such as glucose, oxygen, and carbon dioxide redistribute themselves through semipermeable membranes from areas of higher concentration to areas of lower concentration. This is how these molecules move across the cell membrane and the capillary wall.
Choice B reason: Osmosis is the process by which water moves through semipermeable membranes from areas of lower solute concentration to areas of higher solute concentration. This is how water balance is maintained across the cell membrane and the capillary wall.
Choice C reason: Blood pressure is the force exerted by the blood on the walls of the blood vessels. It is not a process by which small ions redistribute themselves through semipermeable membranes, but rather a factor that influences the movement of fluids and solutes across the capillary wall.
Choice D reason: Rehydration is the process of restoring the fluid balance in the body by drinking fluids or receiving intravenous fluids. It is not a process by which small ions redistribute themselves through semipermeable membranes, but rather a treatment for dehydration.
Correct Answer is A
Explanation
Choice A reason: For an average adult, the total intake should be approximately equal to the total output every day¹². Therefore, if the patient's total output is 2200 mL, the total intake should also be around 2200 mL.
Choice B reason: 3000 mL is more than the recommended daily fluid intake for an average adult, which is about 2500 mL³. If the patient's intake is higher than their output, they may develop fluid overload or edema.
Choice C reason: 3800 mL is much more than the recommended daily fluid intake for an average adult, which is about 2500 mL³. If the patient's intake is higher than their output, they may develop fluid overload or edema.
Choice D reason: 2400 mL is slightly less than the recommended daily fluid intake for an average adult, which is about 2500 mL³. However, if the patient's intake is lower than their output, they may develop dehydration or electrolyte imbalance.
