UTA FNP 2 MIDTERM, MODULE 1 ENT & UPPER AIRWAY

WITH 100% VERIFIED!!

Blepharitis, pharm Antibiotic ointments - (BEQ)

o Bacitracin, erythromycin, and quinolone (any -floxacin).

o If infx doesn't respond to topical meds, if you have resistant infections - use oral antibiotics.

· First line - doxycycline 100mg PO twice a day.

· Tetracycline 250 mg 4 times daily can also be given.

Blepharitis, anterior presentation o Staphylococcal blepharitis characterized by scaling, crusting, and erythema of the eyelid margin, more common among women in their 40s. o Eyelid staph infection - Eyelash loss; crusting or matting of eyelashes upon waking; flaking or scaling of eyelid skin.

Blepharitis, posterior presentation o Inflammation and dysfunction of the meibomian gland within eyelid.

o Excess foamy discharge, chalazion (aka meibomian cyst, is a small, firm, painless bump that develops on the eyelid), and ocular rosacea is common.

Conjunctivitis, bacterial, presentation o Sclera of the eye gets red, and sometimes itchy, and sometimes there will be exudates.

§ Typically, if you see the exudates, it is bacterial conjunctivitis.

o The organisms that cause the bacteria are Staph, Strep, H flu, and M catarrhalis same as upper respiratory infx.

o Pseudomonas is another less likely cause and, of course, gonorrhea can cause it as well.

Conjunctivitis, bacterial, pharm o Pharm - § Azithromycin 1% solution § Erythromycin 0.5% ointment § Gentamicin 0.3% solution § Sulfacetamide 10% (Bleph-10, Isopto Cetamide, or Sodium Sulamyd) § Tobramycin (Tobrex) § Bacitracin/polymyxin B 500 u/g ointment § Ciprofloxacin 0.3% (Ciloxan) § Ofloxacin 0.3% (Ocuflox)

Corneal Abrasion, pharm · Pharm

o Eye rx Ciprofloxacin.

§ Want to use broad spectrum.

Cataracts, assessment · Assessment - o Opacification of the lens. o Diminished red reflex and a white reflex. o Blurred vision and see halo around lights. o Diminished night vision, and diminished visual acuity.

Strabismus, different types/patterns · Different types - o Esotropia - where the eye drifts inward. o Exotropia - where it drifts outward. o Hypertropia - where it drifts upward. o Hypotropia - where it drifts downward.

Glaucoma, excessive IOP value

25mmHg

Glaucoma, tonometer use · You take an average of three readings. Normal pressure is 10 to 23. Anything 25 or greater is considered close angled glaucoma.

Glaucoma, categories of meds beta blockers (5), prostaglandin analogs (4), carbonic anhydrase inhibitors (2), alpha adrenergic (2).

Glaucoma, open angle, beta blockers o Five beta blockers betaxolol, carteolol, levobunolol, metipranolol, and timolol.

§ These medications decrease aqueous humor production. Can have systemic side effects typical of beta blockers if there is enough systemic absorption.

Glaucoma, open angle, prostaglandin analogs o latanoprost, travoprost, bimatoprost, and tafluprost.

§ These medications work by increasing aqueous humor outflow. These can cause brown pigmentation of the iris. The patient needs to be educated about this side effect.

· Miosis · Contraction of the ciliary muscle § Now considered a second-line drug for open-angle glaucoma. § Emergency treatment of acute angle-closure glaucoma

Diabetic retinopathy, assessment Assessment - · Subjective visual changes · Fundoscopic exam - microaneurysms, intra-retinal hemorrhage, macular edema, and lipid deposits. There will also be cotton wool spots, venous beading and dilation, edema, and in some cases, retinal hemorrhage.

diabetic retinopathy, pharm Pharm - · Lisinopril - The only pharmacologic agent found to slow the progression.

macular degeneration, define dry vs wet

  • dry ’ – Is a slow progressive atrophy and degeneration of the retina.
  • wet ’ – Age related, new blood vessels develop under the retina in the macula and cause sudden distortion or loss of central vision. These patients need to be referred out

macular degeneration, assessment

Assessment

· If the vision is less than 20/20 do a pinhole test. If vision corrects with the pinhole this implies uncorrected refractive error.

· With refractive error, fundoscopic exam is usually normal. Yellow spots or drusen spots may be indicative of early macular degeneration. These are in clumps of pigment and irregularly interspaced.

Vertigo, most common cause One of the most common causes of vertigo is benign paroxysmal positional vertigo (BPPV). · BPPV is caused by sediment, such as calcium carbonate crystals, that have become free floating within the inner ear.

vertigo - another common cause ___ Another common cause of vertigo is vestibular neuronitis or labyrinthitis.

· It is thought to be caused by inflammation, secondary to a viral infection, of the vestibular portion of the eighth cranial nerve or of the inner ear balance organs (vestibular labyrinth).

· The patient will usually awaken with room-spinning vertigo that will gradually become less intense over 24 48 hours.

· Salt restriction and thiazide diuretics are frequently used as first-line agents.
