A client who has polycystic kidney disease (PKD) presents to the emergency department with reports of a severe headache. Which of the following complications should the nurse expect?

Choice A reason: While a heart atack is a serious condition, it is not directly related to peritonitis. Peritonitis can lead to systemic infection, which may indirectly affect the heart, but it is not the primary concern in the immediate care of peritonitis.

Choice B reason: Diabetes is a chronic condition that requires ongoing management. However, it is not the most immediate threat when a client is diagnosed with peritonitis. The nurse should continue to monitor blood glucose levels as part of routine care.

Choice C reason: Respiratory failure can be a complication of peritonitis if the infection spreads and affects other systems. However, the primary concern with peritonitis is the potential for the infection to lead to sepsis.

Choice D reason: Sepsis is a life-threatening condition that can occur as a complication of peritonitis. It happens when the body's response to infection causes injury to its own tissues and organs. Monitoring for signs of sepsis is crucial because early intervention can be lifesaving.

Choice A reason: A distended bladder can cause low back pain due to the pressure and stretching of the bladder wall, which is often related to a urinary disorder such as urinary retention or obstruction.

Choice B reason: A stress fracture is less likely to be the cause of low back pain associated with an inability to void and a distended bladder.

Choice C reason: Nerve root pain typically presents with radiating pain down the leg rather than low back pain associated with urinary symptoms.

Choice D reason: Renal cancer could potentially cause low back pain, but it would not typically cause an inability to void or a distended bladder without other significant symptoms.
