In the context of cardiogenic shock managed with vasopressor and inotrope therapies, organ dysfunction from hypoperfusion can manifest as elevated creatinine and abdominal pain. Elevated creatinine indicates renal impairment, a common result of poor perfusion to the kidneys. Abdominal pain can indicate hypoperfusion to the gastrointestinal tract, leading to ischemic bowel or other GI complications. These symptoms are direct indicators of hypoperfusion and organ dysfunction. References: = CCRN Exam Handbook, AACN Adult CCRN Certification Review Course

Meningitis

A positive Kernig’s sign is a clinical test for meningitis that involves flexing the hip and knee of the patient and then extending the knee. If the patient feels pain or resistance in the lower back or hamstring, the test is positive. A positive Kernig’s sign indicates irritation of the meninges, the membranes that cover the brain and spinal cord. A positive Trousseau’s sign is a sign of hypocalcemia that involves carpal spasm after inflating a blood pressure cuff. A positive Cullen’s sign is a sign of retroperitoneal bleeding that involves bruising around the umbilicus. A positive Babinski’s sign is a sign of upper motor neuron lesion that involves fanning of the toes when the sole of the foot is stroked.

Anaphylactic shock is characterized by widespread vasodilation due to the release of histamine and other inflammatory mediators. This vasodilation causes a significant drop in systemic vascular resistance and maldistribution of blood volume, leading to hypotension. The explanation addresses the pathophysiological changes that occur during anaphylactic shock. References: AACN Adult CCRN Certification Review Course, AACN CCRN Exam Handbook.
