The nurse is providing care for a client with a fluid imbalance. The nurse explains that in the body, areas with high concentration of solutes naturally and passively shift to areas of lower concentration. The nurse is describing which process?
Active transport
Diffusion
Filtration
Osmosis
The Correct Answer is B
Choice A reason: Active transport is the process of moving molecules across a cell membrane against a concentration gradient, requiring energy.
Choice B reason: Diffusion is the process of moving molecules from an area of high concentration to an area of low concentration, without using energy.
Choice C reason: Filtration is the process of moving fluid and solutes through a membrane by a pressure gradient.
Choice D reason: Osmosis is the process of moving water across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.

Correct Answer is D
Explanation
Choice A reason: Slowing the rate to 50 mL/hr is not an appropriate action by the nurse before calling the physician to clarify the order. This could cause the client to become more hypovolemic, which is a condition where there is a decreased volume of blood in the body. Hypovolemia can lead to shock, organ failure, and death.
Choice B reason: Slowing the rate to 20 mL/hr is not an appropriate action by the nurse before calling the physician to clarify the order. This could also cause the client to become more hypovolemic, which is a serious and life-threatening condition. The nurse should not reduce the IV fluid rate without a physician's order.
Choice C reason: Increasing the rate to 250 mL/hr is not an appropriate action by the nurse before calling the physician to clarify the order. This could cause the client to become more hypervolemic, which is a condition where there is an excess of fluid in the blood vessels. Hypervolemia can cause fluid overload, pulmonary edema, and heart failure.
Choice D reason: Continuing the rate at 125 mL/hr is an appropriate action by the nurse before calling the physician to clarify the order. This is a reasonable rate for a client who has a head injury and hypovolemia, as it can help restore the fluid balance and prevent cerebral edema. The nurse should not change the IV fluid rate without a physician's order.
Correct Answer is A
Explanation
Choice A reason: Sudden abdominal pain is a sign of gastrointestinal perforation, which is a life-threatening complication of peptic ulcer disease. It occurs when the ulcer erodes through the wall of the stomach or duodenum, causing leakage of gastric contents into the peritoneal cavity. This causes inflammation, infection, and peritonitis.
Choice B reason: Hyperactive bowel sounds are not indicative of gastrointestinal perforation. They may be present in other conditions, such as gastroenteritis, intestinal obstruction, or diarrhea.
Choice C reason: Bradycardia is not indicative of gastrointestinal perforation. It may be caused by other factors, such as vagal stimulation, medication side effects, or cardiac disorders.
Choice D reason: Decreased blood pressure is not indicative of gastrointestinal perforation. It may be a result of other causes, such as hypovolemia, shock, or dehydration.
