NCLEX-PN
A herniated intervertebral disk (HNP) occurs when the nucleus pulposus (soft inner material) protrudes through the annulus fibrosus (outer ring), compressing adjacent nerve roots or the spinal cord. Most commonly affects L4-L5 and L5-S1 (lumbar) causing sciatica, and C5-C6/C6-C7 (cervical) causing arm radiculopathy. NCLEX-PN tests conservative and surgical management, postoperative log-rolling technique, and neurological monitoring. Run a 60-second scan: breathing work and oxygenation, perfusion and end organs, neuro baseline, likely infection sources, and devices that can fail quietly. When two answers feel partly right, pick the one that reduces imminent harm and matches orders for the role you were given. Train yourself to state the primary risk in one short phrase before you read the options so competing demands do not displace it.
