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.

The patient's tachycardia and hypotension following bowel resection surgery indicate potential severe complications such as hemorrhage or septic shock, which require immediate intervention. If the on-call surgical resident does not provide new orders, the nurse must act promptly to prevent further deterioration by initiating the rapid response team (RRT). The RRT can provide critical interventions and facilitate timely transfer to a higher level of care if needed. References: = CCRN Exam Handbook, AACN Adult CCRN Certification Review Course
