The nurse is aware that small ions such as glucose, oxygen, and carbon dioxide redistribute themselves through semipermeable membranes by a process called
The Correct Answer is {"dropdown-group-1":"A"}
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 C
Explanation
Choice A reason: This is incorrect because this represents respiratory alkalosis, not acidosis. Respiratory alkalosis is characterized by a high pH and a low PCO2.
Choice B reason: This is incorrect because this represents a mixed disorder, not a pure respiratory acidosis. A mixed disorder occurs when both the pH and the PCO2 are abnormal, but in opposite directions.
Choice C reason: This is correct because this represents respiratory acidosis. Respiratory acidosis is characterized by a low pH and a high PCO2.
Choice D reason: This is incorrect because this represents normal values, not respiratory acidosis. Normal values for pH and PCO2 are 7.35 to 7.45 and 35 to 45 mmHg, respectively.
Correct Answer is D
Explanation
Choice A reason: This is incorrect because over-hydration is unlikely in a dehydrated patient. Over-hydration is a condition where the body has too much water, which can cause hyponatremia, edema, and cerebral swelling.
Choice B reason: This is incorrect because diarrhea is a cause, not a consequence, of dehydration. Diarrhea is the frequent and watery passage of stool, which can lead to fluid and electrolyte loss.
Choice C reason: This is incorrect because pulmonary congestion is also unlikely in a dehydrated patient. Pulmonary congestion is a condition where the lungs are filled with fluid, which can cause dyspnea, cough, and crackles.
Choice D reason: This is correct because fall is a potential complication of dehydration. Dehydration can cause confusion, dizziness, weakness, and hypotension, which can increase the risk of falling and injuring oneself.
