A red eye is usually conjunctivitis and occasionally sight-threatening, so the exam tests the discriminators: pain, photophobia, and reduced visual acuity. These questions cover the red-eye differential, viral versus bacterial versus allergic conjunctivitis, foreign body and corneal abrasion, acute angle-closure glaucoma, and the vision changes that require same-day ophthalmology. Those 3 discriminators run through all 10 questions, at Family Nurse Practitioner board depth.
Question 1
An 82-year-old female with severe Alzheimer's disease requires total assistance with bathing and feeding. Her husband reports feeling profoundly exhausted and frequently tearful over the past month. What is the most appropriate guidance for the FNP to provide?
- A) Advise the husband to hire a live-in registered nurse.
- B) Recommend the husband start a daily antidepressant medication trial.
- C) Facilitate a referral for local adult day care services.✓
- D) Suggest the husband take an extended weekend vacation alone.
💡 Key Takeaway
Respite care referrals are essential for mitigating severe caregiver burnout and depression.
Show rationale
When a caregiver for a patient with severe Alzheimer's disease is profoundly exhausted and frequently tearful, the priority is providing structured respite. Adult day care services offer safe patient supervision while giving the caregiver a necessary break. Option A is financially unrealistic for most families and not the standard initial recommendation. Option B ignores the root cause of caregiver burden, which requires practical support first. Option D is impractical without first establishing alternative care arrangements for the patient.
Question 2
A 72-year-old smoker presents with a 2-day history of straight lines appearing wavy. Fundoscopy reveals a subretinal hemorrhage in the right eye.
- A) Arrange urgent evaluation by a retinal ophthalmologist.✓
- B) Recommend daily Amsler grid monitoring at home.
- C) Initiate high-dose antioxidant vitamin supplementation therapy.
- D) Schedule routine optometry follow-up in four weeks.
💡 Key Takeaway
Sudden onset metamorphopsia requires an urgent ophthalmology referral to evaluate for wet macular degeneration.
Show rationale
The patient's presentation of sudden metamorphopsia and hemorrhage strongly suggests wet macular degeneration, which is a vision-threatening emergency. You should arrange an urgent ophthalmology referral because timely anti-VEGF therapy can preserve vision. Option B is incorrect because while the Amsler grid monitors progression, it delays necessary immediate treatment for acute changes. Option C is wrong since antioxidant vitamins are indicated to slow dry macular degeneration, not to treat acute wet disease. Option D is inappropriate because a routine four-week follow-up would likely result in irreversible central vision loss due to the rapid progression of neovascularization.
Question 3
An 88-year-old patient recovering from hip fracture becomes acutely delirious and is trying to climb out of bed, presenting a high fall risk. Which intervention is most appropriate to ensure safety?
- A) Request a family member to sit bedside.✓
- B) Apply a vest restraint to prevent injury.
- C) Administer oral diphenhydramine to induce calming sedation.
- D) Raise all four bed rails for safety.
💡 Key Takeaway
1:1 observation by family or a sitter is preferred over physical or chemical restraints for delirious patients.
Show rationale
Using a sitter or family member provides necessary supervision and reorientation without the negative effects of physical or chemical restraints. Option B and D act as physical restraints, which increase agitation and the risk of severe injury if the patient attempts to climb over them. Option C uses an anticholinergic medication, which is highly likely to worsen delirium and increase fall risk in older adults.
Question 4
An 80-year-old male tripped on a curb while walking outdoors. He recently started wearing new progressive bifocal lenses and has a history of moderate bilateral cataracts.
- A) Advise using single-vision distance glasses when outdoors.✓
- B) Refer immediately for bilateral cataract extraction surgery.
- C) Recommend a quad cane for outdoor ambulation.
- D) Prescribe a daily lubricating eye drop therapy.
💡 Key Takeaway
Avoiding multifocal lenses during outdoor ambulation improves depth perception and reduces fall risk on uneven terrain.
Show rationale
Older adults wearing multifocal lenses, such as progressive bifocals, have a significantly higher risk of tripping on stairs and curbs because these lenses impair depth perception and lower-field contrast sensitivity. Advising the patient to switch to single-vision distance glasses when navigating outdoors directly mitigates this specific environmental risk. Referring immediately for bilateral cataract extraction surgery is an overreaction to a single tripping incident, as cataract surgery requires comprehensive ophthalmologic evaluation and scheduling. Recommending a quad cane for outdoor ambulation is overly restrictive and inappropriate for a patient who does not have a documented gait or balance deficit requiring an assistive device. Prescribing a daily lubricating eye drop therapy is a treatment for dry eyes and will not improve the visual spatial deficits caused by multifocal lenses.
Question 5
A 30-year-old female experiences a gradual onset of scintillating scotoma that is expanding over 20 minutes, which is immediately followed by unilateral throbbing headache.
- A) Transient ischemic attack
- B) Typical retinal migraine
- C) Occipital lobe seizure
- D) Migraine with typical aura✓
💡 Key Takeaway
Migraine auras feature gradually expanding positive visual phenomena lasting minutes before the headache phase begins.
Show rationale
Migraine with typical aura features visual symptoms like scintillating scotomas that gradually expand over several minutes before the headache phase begins. Transient ischemic attacks typically present with sudden, negative visual symptoms like vision loss rather than gradual, positive visual phenomena. Retinal migraines cause strictly monocular visual disturbances, not binocular scotomas. Occipital seizures cause very brief visual flashes lasting only seconds, rather than expanding over 20 minutes.
Question 6
A 76-year-old patient with Parkinson's disease reports frequent tripping over throw rugs in the hallway. The patient also has declining visual acuity from macular degeneration and poor lighting in the home. Which referral is most appropriate to directly address these specific fall risks?
- A) Optometry for immediate visual acuity correction
- B) Occupational therapy for environmental hazard mitigation✓
- C) Physical therapy for lower extremity strengthening
- D) Home health aide for daily mobility assistance
💡 Key Takeaway
Occupational therapists specialize in mitigating environmental hazards and adapting homes for patients with visual or motor deficits.
Show rationale
The most appropriate referral is occupational therapy because they excel at environmental hazard mitigation, such as removing throw rugs and optimizing home lighting for patients with visual impairments. While optometry is important, macular degeneration is progressive and cannot always be immediately corrected with lenses, making environmental adaptation crucial. Physical therapy is highly effective for lower extremity strengthening and Parkinson's gait training, but it does not directly alter the physical hazards in the home environment. A home health aide provides supervision and assistance but lacks the specialized training to formally evaluate and modify the home for long-term safety.
Question 7
A 28-year-old female presents to the clinic seeking pharmacotherapy for weight loss. She has a body mass index of 32 kg/m2 and reports a strong family history of medullary thyroid carcinoma. She specifically requests a prescription for a once-weekly injectable medication she saw on television. Which of the following is the most appropriate action?
- A) Initiate semaglutide and monitor thyroid function tests closely.
- B) Avoid GLP-1 agonists and prescribe phentermine-topiramate instead.✓
- C) Start liraglutide at the lowest available initial dosage.
- D) Order a thyroid ultrasound before prescribing any tirzepatide.
💡 Key Takeaway
GLP-1 agonists are contraindicated in patients with a personal or family history of medullary thyroid carcinoma.
Show rationale
GLP-1 receptor agonists are an excellent choice for weight management, but they carry an absolute contraindication for patients with a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2. Because of this risk, option B is the best choice; you should select an alternative weight loss medication. Options A, C, and D are incorrect because initiating any GLP-1 or GIP/GLP-1 agonist, even at a low dose or with close monitoring and ultrasound imaging, violates this strict safety contraindication and places the patient at unnecessary risk.
Question 8
A 24-year-old male presents with a two-week history of unilateral follicular conjunctivitis, mild purulent discharge, and a palpable preauricular lymph node. He reports recently being treated for a urogenital infection. Which pharmacotherapeutic approach is most appropriate?
- A) Topical erythromycin ophthalmic ointment therapy
- B) Oral azithromycin systemic single dose therapy✓
- C) Topical gatifloxacin ophthalmic solution therapy
- D) Oral acyclovir systemic daily dose therapy
💡 Key Takeaway
Adult inclusion conjunctivitis caused by Chlamydia requires systemic antibiotic therapy for resolution.
Show rationale
A chronic follicular conjunctivitis with preauricular adenopathy in a sexually active adult strongly suggests chlamydial inclusion conjunctivitis. Because this is a systemic infection presenting with ocular symptoms, it requires systemic treatment with oral azithromycin or doxycycline. Topical antibiotics like erythromycin or gatifloxacin will not eradicate the underlying chlamydial reservoir and are insufficient. Oral acyclovir is indicated for herpetic viral infections, which typically present with vesicular lesions or dendritic ulcers, not purulent follicular conjunctivitis.
Question 9
An 8-month-old infant presents with a low-grade fever and fussiness. Otoscopic examination reveals bilateral acute otitis media. The infant attends daycare but has had no recent antibiotic exposure and has no known drug allergies. Which intervention is most appropriate?
- A) Start high-dose amoxicillin liquid therapy✓
- B) Start standard-dose amoxicillin liquid therapy
- C) Start high-dose amoxicillin-clavulanate therapy
- D) Start watchful waiting with pain control
💡 Key Takeaway
High-dose amoxicillin is the first-line treatment for acute otitis media in infants without recent antibiotic exposure.
Show rationale
Infants between 6 and 23 months of age with bilateral acute otitis media require immediate antibiotic therapy regardless of symptom severity, making watchful waiting inappropriate. Because this infant has not had amoxicillin in the past 30 days and lacks concurrent purulent conjunctivitis, high-dose amoxicillin at 80 to 90 mg/kg/day is the guideline-directed first-line therapy. Standard-dose amoxicillin is insufficient to overcome potential intermediate-resistant Streptococcus pneumoniae. Amoxicillin-clavulanate is unnecessarily broad for a first-line approach and is reserved for patients who have received amoxicillin recently or have a history of recurrent infections unresponsive to amoxicillin.
Question 10
A 28-year-old female reports a recurrent unilateral throbbing headache that is worsened by climbing stairs and is frequently accompanied by nausea. Her neurological examination is completely normal.
- A) Episodic tension-type headache
- B) Migraine without aura✓
- C) Secondary headache disorder
- D) Episodic cluster headache
💡 Key Takeaway
Migraine without aura features unilateral throbbing pain aggravated by routine activity and accompanied by nausea.
Show rationale
Migraine without aura is characterized by unilateral throbbing pain that is worsened by routine physical activity and is often accompanied by nausea or photophobia. Tension headaches are bilateral, non-throbbing, and are not worsened by routine physical activity. Secondary headaches usually present with red flags, such as an abnormal neurologic exam or sudden onset. Cluster headaches feature severe orbital pain with prominent autonomic signs, lacking prominent nausea as a primary symptom.
