A nurse is admitting a client with a history of duodenal ulcer. To determine if the client's current symptoms are related to this information, the nurse should assess the client for which manifestations of a duodenal ulcer?

Choice A reason: Disequilibrium syndrome is characterized by headache, nausea, and agitation, which can occur during or after hemodialysis, especially in the first few sessions as the body adjusts to the treatment².

Choice B reason: Septicemia would typically present with fever, chills, and hypotension, not specifically headache and agitation².

Choice C reason: Air embolism is a rare complication that would present with sudden respiratory distress, chest pain, and possibly hypotension, not just headache and agitation².

Choice D reason: Peritonitis is associated with abdominal pain and tenderness, fever, and possibly altered bowel movements, not the symptoms described².

Choice A reason: Bradycardia, which is a slower than normal heart rate, is not a common finding associated with renal calculi. Renal calculi, or kidney stones, typically cause symptoms related to the urinary system rather than directly affecting the heart rate.

Choice B reason: Bradypnea, or abnormally slow breathing, is also not a typical symptom of renal calculi. Patients with kidney stones may experience changes in urination patterns, such as frequency or urgency, but not typically changes in respiratory rate.

Choice C reason: Severe pain is indeed the most common symptom associated with renal calculi. This pain, known as renal colic, is often sudden in onset, very severe, and may radiate from the back down to the lower abdomen or groin. The pain is caused by the stone moving into the ureter and causing a blockage, which leads to increased pressure and stretching of the kidney or ureter. Renal calculi can cause a range of symptoms, with severe pain being the most prominent and often the first symptom that leads individuals to seek medical care. The pain is typically very intense and can be accompanied by other symptoms such as nausea, vomiting, and hematuria (blood in the urine).

Choice D reason: Nocturia, or frequent urination at night, can be a symptom of renal calculi, especially if the stones affect the bladder or cause urinary tract infections. However, the most characteristic symptom of renal calculi is severe pain, not necessarily nocturia.
