A client with a peptic ulcer is diagnosed with Helicobacter pylori infection. The nurse is teaching the client about the medications prescribed, including two antibiotics metronidazole and clarithromycin and a PPI omeprazole. Which statement by the client indicates the best understanding of the medication regimen?

Choice A reason: This is a correct answer because normal saline is an isotonic solution, which means it has the same osmolarity as the blood plasma. It does not cause any fluid shifts between the intracellular and extracellular compartments, and it can help restore the fluid balance and the blood pressure of the dehydrated client.

Choice B reason: This is not a correct answer because 1/2 normal saline is a hypotonic solution, which means it has a lower osmolarity than the blood plasma. It causes fluid to shift from the extracellular to the intracellular compartment, which can lead to cellular swelling and edema. It is not suitable for rapid infusion, as it can cause hemolysis and hypotension.

Choice C reason: This is not a correct answer because D5W (5% Dextrose in Water) is an isotonic solution when it is in the IV bag, but it becomes hypotonic once it enters the body, as the dextrose is rapidly metabolized and only water remains. It causes fluid to shift from the extracellular to the intracellular compartment, which can lead to cellular swelling and edema. It is not suitable for rapid infusion, as it can cause hemolysis and hypotension.

Choice D reason: This is not a correct answer because D5 1/2 normal saline is a hypertonic solution, which means it has a higher osmolarity than the blood plasma. It causes fluid to shift from the intracellular to the extracellular compartment, which can lead to cellular shrinkage and dehydration. It is not suitable for rapid infusion, as it can cause hypernatremia and fluid overload.

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.
