A client presents to the clinic reporting vomiting and burning in her mid-epigastric area. The nurse knows that in the process of confirming peptic ulcer disease, the health care provider is likely to order a diagnostic test to detect the presence of what?

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.

Choice A reason: This is not a correct manifestation of appendiceal perforation. Blanched abdomen means that the skin of the abdomen is pale or white, which can indicate shock or blood loss. However, it is not a specific sign of appendiceal perforation, as it can occur in other conditions as well.

Choice B reason: This is a correct manifestation of appendiceal perforation. Sudden decrease in abdominal pain means that the pain that was previously felt in the right lower quadrant of the abdomen has subsided or disappeared. This can indicate that the appendix has ruptured and released the pus and bacteria into the peritoneal cavity, causing peritonitis. This is a serious complication that requires immediate surgical intervention.

Choice C reason: This is not a correct manifestation of appendiceal perforation. Absent Rovsing's sign means that there is no pain in the right lower quadrant of the abdomen when the left lower quadrant is palpated. This is a sign of appendicitis, not appendiceal perforation, as it indicates that the appendix is inflamed and irritated by the pressure.

Choice D reason: This is not a correct manifestation of appendiceal perforation. Fever means that the body temperature is above the normal range, which can indicate infection or inflammation. However, it is not a specific sign of appendiceal perforation, as it can occur in other conditions as well.
