NR 511 DIFFERENTIAL DIAGNOSIS
Enhanced Week 4 Midterm Study Guide
Original exam-oriented review • Primary Care Practicum
Requested source: Stuvia lists a 16-page 2019/2020 NR511 Week 4 Midterm (version 4). Its public preview spans
musculoskeletal, endocrine, neurologic, dermatologic, GI/GU, reproductive health, burns, ethics, coding, prevention,
and primary-care management. ■cite■turn0view0■

, 1. What the Public Preview Signals
The preview includes questions on shoulder dislocation, rheumatoid arthritis, Graves disease, delirium, confidentiality, burns,
gout, postpartum depression, Lyme disease, abnormal vaginal bleeding, carpal tunnel syndrome, prostate cancer, diabetic foot
care, trichomoniasis, poisoning, wound irrigation, hypothyroidism, herpes zoster, cluster headache, HIV treatment, BMI, NSAID
teaching, APRN regulation, herniated disc, pneumothorax, skin lesions, testicular masses, vaginal microscopy, palliative care,
prevention, migraine prophylaxis, HPV, diabetic foot exams, bacterial vaginosis, thyroid follow-up, malpractice prevention, GAD,
testicular cancer, and cauda equina syndrome. ■cite■turn0view0■
Current related NR511 material continues to emphasize differential diagnosis using discriminating findings—for example,
recurrent axillary nodules with scarring suggest hidradenitis suppurativa, while eye redness with scant discharge, gritty sensation,
and preauricular nodes points toward viral conjunctivitis. ■cite■turn0search0■turn0search2■
Study rule: identify the syndrome, the dangerous diagnosis that must not be missed, the most discriminating finding, and the next
best step.

, 2. Clinical Reasoning Framework
• Stability first: identify airway, breathing, circulation, neurologic compromise, sepsis, major bleeding, or rapidly progressive
disease.
• Define the syndrome: location, onset, time course, severity, associated symptoms, exposures, medications, and risk factors.
• Build a short differential: common, dangerous, and reversible diagnoses.
• Use discriminators: one finding may sharply separate competing diagnoses.
• Choose testing that answers a clinical question rather than ordering everything.
• Safety-net with red flags and follow-up when outpatient management is reasonable.
Must-not-miss red flags
• Cauda equina: urinary retention/incontinence, saddle anesthesia, progressive bilateral weakness → emergency evaluation.
• Acute hot swollen joint with fever/systemic illness → consider septic arthritis.
• Sudden severe headache or focal neurologic deficit → evaluate for secondary causes.
• Firm intratesticular mass → malignancy must be excluded.
• Abnormal uterine bleeding in reproductive-age patients → exclude pregnancy early.
