A nurse is caring for a client who reports a new onset of severe chest pain. Which of the following actions should the nurse take to determine if the client is experiencing a myocardial infarction?

Choice A: Hyperglycemia The reason hyperglycemia is a risk when the prescribed dwell time is not maintained is due to the glucose present in the dialysate. The dialysate used in PD often contains glucose, which acts as an osmotic agent to facilitate fluid removal from the blood. If the dwell time is too short, there may not be enough time for the glucose to be absorbed, leading to higher levels of glucose in the blood. Conversely, if the dwell time is too long, excessive glucose absorption can occur, also leading to hyperglycemia. For patients with diabetes mellitus, maintaining the prescribed dwell time is essential to manage their blood glucose levels effectively. The normal range for fasting blood glucose is typically between 70 to 99 mg/dL, and for diabetes patients, maintaining blood glucose levels as close to the normal range as possible is crucial to prevent complications.

Choice B: Disequilibrium Syndrome Disequilibrium syndrome is characterized by neurological symptoms resulting from rapid changes in the composition of extracellular fluids during dialysis. This condition is more commonly associated with hemodialysis due to the rapid shifts that can occur with this modality. In PD, the risk of disequilibrium syndrome is significantly lower because the exchange of solutes and fluids is more gradual. Therefore, while important to consider, it is not the primary complication associated with the maintenance of dwell time in PD.

Choice C: Peritonitis Peritonitis, an infection of the peritoneal cavity, is a serious complication of PD but is not directly related to the duration of dwell time. It is typically caused by contamination during the exchange process or catheter-related infections. While proper technique and hygiene are critical in preventing peritonitis, the dwell time itself does not influence the risk of developing this infection.

Choice D: Hyperphosphatemia Hyperphosphatemia refers to elevated levels of phosphate in the blood and is a concern in patients with renal failure due to the kidneys’ inability to excrete phosphate effectively. The dwell time in PD may affect the removal of phosphate to some extent; however, it is not the primary concern related to the maintenance of dwell time. Phosphate binders and dietary restrictions are commonly used to manage phosphate levels in PD patients.

Tachycardia, or a rapid heartbeat, is a common response to the pain and stress associated with stomach perforation. The body’s sympathetic nervous system is activated in response to the pain and the potential shock state due to internal bleeding or infection, leading to an increased heart rate. Tachycardia is also a compensatory mechanism to maintain adequate blood flow and oxygen delivery to vital organs in the setting of decreased blood volume. A stomach perforation due to a peptic ulcer is a serious medical condition where an ulcer has led to a hole in the stomach lining. This can lead to the contents of the stomach spilling into the abdominal cavity, causing peritonitis, which is an inflammation of the peritoneum (the lining of the abdominal cavity).

Choice B: Rebound tenderness

Rebound tenderness is a clinical sign that indicates irritation of the peritoneum. When pressure is applied to the abdomen and then quickly released, the sudden movement of the peritoneal layers against each other produces sharp, rebound pain. This is a classic sign of peritonitis, which can occur with stomach perforation as gastric contents irritate the peritoneum. When assessing a client with a suspected stomach perforation due to a peptic ulcer, a nurse should expect to find signs of tachycardia, rebound tenderness, and a rigid abdomen. These findings are indicative of the body’s response to the acute abdominal condition and peritoneal irritation. It is crucial to recognize these signs promptly as stomach perforation is a medical emergency requiring immediate intervention.

Choice C: Rigid abdomen

A rigid abdomen is indicative of involuntary guarding, a reflex contraction of the abdominal muscles to protect inflamed organs within the abdomen. This rigidity is a sign of peritoneal irritation and is often present in cases of stomach perforation. The rigidity helps to immobilize the area, which may reduce pain but also serves as a clinical indicator of serious intra-abdominal pathology.

Choice D: Elevated blood pressure

Elevated blood pressure is not typically a direct result of stomach perforation. In fact, blood pressure may initially be normal or even low, depending on the body’s response to internal bleeding and the potential development of shock. However, pain and anxiety can cause a transient increase in blood pressure, but it is not a primary diagnostic criterion for stomach perforation.
