Ophthalmology, Otolaryngology, and Pulmonology Exam Prep — Certification Guide for Physician Assistants

Preparing for your physician assistant certification or recertification exam? This high-yield podcast summary covers the most critical concepts in ophthalmology (eye disorders), otolaryngology (ear, nose, and throat), and pulmonology (respiratory system) from A Comprehensive Review for the Certification and Recertification Examinations for Physician Assistants. Mastering these topics is essential for exam success and clinical practice.

Ophthalmology: Key Eye Disorders

• Eye Trauma: Immediate management includes shielding the eye, avoiding pressure, and consulting ophthalmology for penetrating injuries.
• Blow-out Fracture: Presents with swelling, misalignment, and impaired eye movement; diagnosis confirmed by CT scan.
• Corneal Abrasion & Ulcer: Abrasions cause pain and photophobia, diagnosed with fluorescein staining; ulcers are typically infectious and painful.
• Retinal Disorders: Retinal detachment leads to painless vision loss; macular degeneration causes central vision loss, especially with age.
• Artery & Vein Occlusion: Sudden changes in vision—medical emergencies.
• Glaucoma: Angle-closure glaucoma is an acute emergency; open-angle glaucoma is a chronic, often silent disease.
• Common Eye Infections: Includes conjunctivitis (bacterial, viral, or allergic) and orbital cellulitis, particularly in children.

Otolaryngology: Ear, Nose, and Throat Disorders

• Ear Disorders: Differentiate conductive vs. sensorineural hearing loss; recognize Ménière disease (vertigo, tinnitus, hearing loss); manage otitis media (acute or chronic).
• Vertigo: Causes include labyrinthitis, vestibular neuritis, and central nervous system disorders.
• Nose and Throat: Acute/chronic sinusitis, types of rhinitis, oral conditions (aphthous ulcers, candidiasis, leukoplakia).
• Serious ENT Conditions: Epiglottitis (life-threatening), peritonsillar abscess, laryngitis.

Pulmonology: Respiratory Disorders

• Asthma: Chronic airway inflammation and episodic symptoms.
• Chronic Obstructive Pulmonary Disease (COPD): Includes emphysema and chronic bronchitis.
• Pneumonia: Presents with fever, cough, infiltrates; can be bacterial, viral, or fungal.
• Pulmonary Emergencies: Pneumothorax (air in the pleural space, potential lung collapse), pulmonary embolism (sudden, life-threatening obstruction of lung arteries).

Glossary of Key Terms

• Blow-out Fracture: Fracture of the orbital floor due to trauma.
• Dacryocystitis: Inflammation of the lacrimal sac.
• Epistaxis: Nosebleed, commonly from the Kiesselbach plexus.
• Photophobia: Sensitivity to light.
• Strabismus: Misalignment of the eyes.
• Otalgia: Ear pain.
• Tinnitus: Ringing in the ears.
• Pneumothorax: Air in the pleural space, causing lung collapse.

Conclusion: Key Takeaways for Exam Success

Mastering the core conditions in ophthalmology, otolaryngology, and pulmonology is vital for passing your physician assistant exams and delivering quality patient care. Focus on emergency presentations, proper diagnostics, and first-line management strategies. Review common signs, symptoms, and terminology frequently tested on certification exams.
