EXAM 1 NR 545 - (ANSWER)Exam Coverage
Exam coverage for NR 545 Exam 1 includes foundational nurse practitioner concepts typically focused on
advanced health assessment, diagnostic reasoning, and primary care management. It emphasizes
comprehensive patient assessment, differential diagnosis, common acute and chronic conditions, and
evidence-based treatment planning. The exam also evaluates understanding of pharmacologic principles,
clinical guidelines, and interpretation of diagnostic tests.
Emphasis is placed on clinical decision-making, prioritization, safe prescribing practices, and applying
advanced n
Allergic conjunctivitis: - (ANSWER)IgE mediated disease in response to triggers. Common triggers can be
seasonal such as grass, pollens, and mold. Persistent allergic triggers include dust mites and animal
dander.
Bilateral, itchy red eyes with rope like discharge and clear nasal discharge
Bilateral injected conjunctiva, clear discharge
Treatment based on identification and limiting exposure to allergen.
Medications include cromolyn ophthalmic drops, oral antihistamines, antihistamine eye drops
Viral conjunctivitis: - (ANSWER)Most commonly caused by the adenovirus.
Unilateral or bilateral red eyes, reports of current or recent viral infection, such as a UTI
Unilateral or bilateral injected conjunctiva, watery discharge
No antibacterial therapy needed.
Virus resolves in 2-3 weeks
Bacterial conjunctivitis: - (ANSWER)Common bacteria include: Staphylococci, streptococci, chlamydial
organisms and gonococci.
Some bacterial causes can be quite serious.

Gonococcal conjunctivitis can result in blindness and can indicate underlying systemic infection.
Usually unilateral, red and irritated
Eyelids are "stuck together" upon awakening.
Injected palpebral and bulbar conjunctiva, purulent drainage
Treatment is provided to decrease spread of contagion and shorten course of illness.
Eye drop treatments include Polymixin B plus trimethoprim or azithromycin.
Otitis Externa - (ANSWER)inflammation of the externa ear canal, is also known commonly as swimmer's
ear. Occurring in both children and adults, otitis externa can present as a range of physical symptoms
from a minor inflammation to reports of intense pain.
Otitis Externa Risk Factors
Swimming
Impacted cerumen
Use of hearing aids/ear plugs
Trauma from cotton tip applicators or other items used to clean ear canal
Foreign bodies
Anatomic causes: narrow ear canals, sharp angles in the ear canal or excessive hair in the canal
The normally acidic pH of the ear canal tends to inhibit microorganism growth. Swimming in a pool
where the pH is usually alkaline can result in altered pH of the ear canal. It is thought that it is this
alteration in pH creates a favorable environment for bacteria or fungal growth. The most common
causative agent is P. aeruginosa, other causes include Candida or Aspergillus species.
Common complaints (subjective findings):
Children: irritability, crying, disrupted sleep. Unilateral ear tugging, unilateral otalgia
Adults: unilateral otalgia
Physical exam (objective findings): Ear pain is increased upon palpation of tragus. The external ear canal
epithelium edema may extend from the pinna all the way to the tympanic membrane. Purulent or
serous discharge is noted in the canal.
