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?

Choice A reason: Decreased heart rate is not a manifestation of hypovolemia. Hypovolemia is a condition where there is a decreased volume of blood in the body, which can result from blood loss, dehydration, or fluid shifts. Hypovolemia can cause the heart rate to increase, not decrease, as the body tries to compensate for the low blood pressure and maintain adequate perfusion.

Choice B reason: Increased blood pressure is not a manifestation of hypovolemia. Hypovolemia can cause the blood pressure to decrease, not increase, as the blood volume and cardiac output are reduced. The body may try to constrict the blood vessels to increase the blood pressure, but this is usually not enough to overcome the effects of hypovolemia.

Choice C reason: Weak pulse is a manifestation of hypovolemia. Hypovolemia can cause the pulse to become weak, thready, or difficult to palpate, as the blood flow and pressure are diminished. The pulse may also become irregular or rapid, as the heart tries to pump faster and harder to deliver oxygen to the tissues.

Choice D reason: Dyspnea is not a specific manifestation of hypovolemia. Dyspnea is a term for difficulty breathing, which can have many causes, such as asthma, pneumonia, or pulmonary edema. Hypovolemia can cause dyspnea if it leads to shock, which is a life-threatening condition where the organs and tissues are not receiving enough oxygen. However, dyspnea alone is not enough to indicate hypovolemia.

Choice A reason: Monitoring respiratory status for signs and symptoms of pulmonary complications is a priority nursing intervention for a client with hypervolemia. Hypervolemia is a condition where there is excess fluid in the blood vessels, which can cause fluid to leak into the lungs and impair gas exchange. The nurse should assess the client for signs of pulmonary edema, such as dyspnea, crackles, cough, and pink-tinged sputum.

Choice B reason: Encouraging the client to consume sodium-free fluids is not a priority nursing intervention for a client with hypervolemia. Sodium-free fluids may still contribute to fluid overload, especially if the client has impaired renal function or heart failure. The nurse should limit the client's fluid intake and administer diuretics as prescribed to reduce the fluid volume.

Choice C reason: Weighing dressings with a large-bore catheter is not a priority nursing intervention for a client with hypervolemia. This may be a relevant intervention for a client with hemorrhage, who may lose blood through a large-bore catheter or dressing. The nurse should monitor the client's blood pressure, pulse, and hemoglobin levels for signs of blood loss.

Choice D reason: Drawing a blood sample for typing and cross-matching is not a priority nursing intervention for a client with hypervolemia. This may be a relevant intervention for a client who needs a blood transfusion, which may be indicated for a client with anemia, trauma, or surgery. The nurse should check the client's blood type and compatibility before administering any blood products.
