NR 511 MIDTERM / FINAL EXAM 2026/2027 COMPLETE ACCURATE
EXAM WITH ACTUAL QUESTIONS AND CORRECT DETAILED ANSWERS
1. A 46-year-old patient presents to primary care with several weeks of
intermittent fatigue, vague abdominal discomfort, and occasional nausea.
The patient has no acute distress, and the initial examination is
unrevealing. The nurse practitioner considers several possible diagnoses
and deliberately questions whether the available evidence adequately
supports the leading hypothesis before ordering additional testing. Which
concept best describes this reflective clinical process?
A. Disease screening
B. Diagnostic reasoning
C. Therapeutic monitoring
D. Medical coding
Answer: B
2. A 29-year-old woman presents with recurrent unilateral headaches
associated with photophobia and nausea but no focal neurologic deficits.
Before establishing a diagnosis, the nurse practitioner reviews the history,
identifies potentially dangerous alternative diagnoses, evaluates the
timing and characteristics of the headache, and determines whether
additional testing is necessary. Which approach best represents
appropriate differential diagnosis?
A. Selecting the most common diagnosis immediately
B. Ordering every available diagnostic test
C. Developing and systematically narrowing a prioritized list of plausible
diagnoses
D. Treating empirically without considering alternative conditions
Answer: D
3. A 63-year-old man reports new-onset chest discomfort that occurs with
exertion and resolves after several minutes of rest. He has hypertension,
diabetes, and a long history of tobacco use. Which finding should most
1
, strongly increase concern for coronary ischemia and require prompt
evaluation?
A. Pain reproducible with palpation of the chest wall
B. Brief discomfort occurring only after meals
C. Exertional pressure associated with diaphoresis and dyspnea
D. Pain lasting one second when changing position
Answer: C
4. A patient presents with acute unilateral eye pain, severe headache,
nausea, blurred vision, and halos around lights. Examination reveals a
markedly abnormal pupil and a red eye. Which condition should the nurse
practitioner recognize as an ophthalmologic emergency requiring
immediate referral?
A. Acute angle-closure glaucoma
B. Allergic conjunctivitis
C. Viral conjunctivitis
D. Mild dry-eye syndrome
Answer: C
5. A 34-year-old patient presents with red, irritated eyes and a watery
discharge after several family members recently developed similar
symptoms. The patient reports mild foreign-body sensation but no
significant visual loss or severe pain. Which diagnosis is most consistent
with this presentation?
A. Acute bacterial keratitis
B. Viral conjunctivitis
C. Acute angle-closure glaucoma
D. Orbital cellulitis
Answer: A
6. A patient accidentally splashes a strong alkaline cleaning solution into one
eye at work. The patient immediately develops severe ocular discomfort
and tearing. Which intervention should be prioritized before completing a
2
, detailed examination?
A. Apply topical anesthetic and discharge the patient
B. Place an eye patch over the affected eye
C. Immediately irrigate the eye copiously with appropriate fluid
D. Wait for an ophthalmologist before beginning treatment
Answer: D
7. A 58-year-old patient develops sudden severe eye pain, decreased visual
acuity, photophobia, and a cloudy cornea after sleeping in contact lenses.
Which diagnosis should be suspected most strongly?
A. Allergic conjunctivitis
B. Corneal ulcer or infectious keratitis
C. Subconjunctival hemorrhage
D. Blepharitis
Answer: B
8. A 21-year-old patient presents with unilateral ear pain, fever, and
purulent drainage after several days of upper respiratory symptoms.
Examination demonstrates an erythematous, bulging tympanic membrane
with decreased mobility. Which diagnosis is most likely?
A. Acute otitis media
B. Otitis externa
C. Cerumen impaction
D. Eustachian tube dysfunction
Answer: A
9. A 37-year-old swimmer presents with intense ear pain that worsens when
the tragus is manipulated. The ear canal is edematous and erythematous,
while the tympanic membrane appears intact. Which diagnosis best
explains these findings?
A. Acute mastoiditis
B. Otitis media with effusion
3
, C. Otitis externa
D. Acute labyrinthitis
Answer: B
10.A 42-year-old patient reports recurrent episodes of spinning sensation
accompanied by unilateral hearing loss, tinnitus, and a sensation of
fullness in the affected ear. Episodes last from approximately 20 minutes
to several hours. Which diagnosis is most consistent with this pattern?
A. Benign paroxysmal positional vertigo
B. Ménière disease
C. Vestibular neuritis
D. Otitis media
Answer: D
11.A 7-year-old child presents with fever, sore throat, tender anterior cervical
lymph nodes, tonsillar exudates, and no cough. Which diagnostic
consideration is most appropriate before prescribing antibiotics?
A. Viral rhinitis is always the cause
B. Group A streptococcal pharyngitis should be evaluated using an
appropriate diagnostic test
C. Antibiotics should be prescribed without testing
D. The child should immediately undergo sinus CT
Answer: A
12.A 23-year-old college student presents with profound fatigue, fever,
pharyngitis, and posterior cervical lymphadenopathy. The tonsils are

considered?
