This comprehensive study guide is designed for nursing students preparing for the NSG-121 Exam 4 at Herzing University. Updated for the 2025/2026 academic year, this A+ graded resource features exam-style questions with verified answers and detailed rationales covering all key topics tested on Exam 4. Key topics covered include: Neurological Assessment: Spinal cord function (carries neuron signals from midbrain to body), brainstem function (controls respiratory and cardiac functions), Broca's area (frontal lobe, responsible for expressive language), Wernicke's area (language comprehension), and communication strategies for patients with aphasia (visual aids, white boards). Neurological Conditions & Stroke: Dysphagia as an aspiration risk after stroke, drowsy vs. stupor levels of consciousness (stupor = unresponsive, aroused only briefly by vigorous stimulation), and African Americans having the highest stroke risk among cultural groups. Pregnancy & Maternity Assessment: HCG as the lab value indicating pregnancy, round ligament pain in the lower abdomen during first trimester, melasma (mask of pregnancy) caused by increased melanin, and nausea as normal only in first trimester. Pediatric Development & Assessment: Infants triple birth weight by 1 year of age, autonomy vs. doubt (18 months to 3 years), industry vs. inferiority (5-12 years), and brighter lights (not dim) for infant assessment. Geriatric Considerations: Increased systolic BP due to calcification/atherosclerosis, decreased taste, limited chest expansion, and fluid volume deficit (dehydration) common in elderly. Infectious Diseases & Microbiology: Pathogens, opportunistic infections, prions, broad vs. narrow spectrum antibiotics, latent viruses, endotoxic shock, Ebola, Zika, Creutzfeldt-Jakob disease, and encephalopathy. Cranial Nerve Assessment: CN I (Olfactory – smell test), CN II (Optic – Snellen chart), CN III/IV/VI (pupillary response and six cardinal positions of gaze), CN V (Trigeminal – sensory touch), CN VII (Facial – taste/facial movements), CN VIII (Acoustic – whisper test), CN IX & X (Glossopharyngeal & Vagus – gag reflex and swallowing), CN XI (Spinal Accessory – shoulder shrug), CN XII (Hypoglossal – tongue movement).
