NR 603 Week 1 Exam (Dizziness – 30+ Questions) – Vertigo, Syncope, Diagnostics, Neuro & Cardiac Causes – Chamberlain University

This document provides over 30 thoroughly answered multiple-choice and clinical reasoning questions on dizziness, featured in the NR 603 Week 1 Exam for the 2025/2026 academic year at Chamberlain University. It is a valuable learning tool for advanced practice students studying adult-gerontology or family primary care, with a detailed exploration of differential diagnosis and management of dizziness-related complaints. Topics covered include the classification and characteristics of vertigo, presyncope, syncope, and disequilibrium, along with their central or peripheral causes. The material explains how to differentiate between vestibular and cardiovascular origins of symptoms using focused history, physical exams (e.g., Dix-Hallpike maneuver, Romberg, Rinne and Weber tests), and diagnostic tools such as audiograms, MRI, and posturography. Clinical indicators for urgent referral, such as focal neurologic deficits or acute labyrinthitis with fever, are also addressed. The document also covers fall risk, the impact of polypharmacy (e.g., antihistamines, anticholinergics, benzodiazepines), and when specialist evaluation is appropriate. This study resource is ideal for: Adult-Gerontology Primary Care Nurse Practitioner (AGPCNP) students Family Nurse Practitioner (FNP) students MSN students learning differential diagnosis in adult care PA and medical students studying neurology and cardiology foundations Clinicians preparing for certification exams in primary care Keywords: NR 603, dizziness, vertigo, syncope, presyncope, disequilibrium, Hallpike-Dix, vestibular testing, Romberg sign, BPPV, labyrinthitis, audiogram, TSH, BMP, ECG, CT MRI, nystagmus, cranial nerves, fall risk, neurologic symptoms, nurse practitioner, Chamberlain University
