Question 1
A 28-year-old pregnant female at 24 weeks gestation presents to the urgent care center
complaining of a severe, throbbing unilateral headache accompanied by nausea and
photophobia. She states these headaches are typical of her pre-pregnancy migraines.
Which of the following acute migraine therapies is strictly contraindicated in this patient
due to the risk of inducing uterine contractions and miscarriage?
A. Acetaminophen
B. Magnesium oxide
C. Ergotamine tartrate
D. Metoclopramide
Answer: C. Ergotamine tartrate
Rationale: Ergotamine tartrate acts as a powerful vasoconstrictor that carries a severe
contraindication during pregnancy. It stimulates uterine smooth muscle contractions and
cuts off uteroplacental blood flow, directly increasing the clinical risk of preterm labor,
spontaneous abortion, or fetal distress. Acetaminophen and metoclopramide are
generally safe options when managed properly.
Question 2
During a wellness visit at a local beach resort clinic, a nurse practitioner evaluates
Benny, a 19-year-old male who presents with a painful, erythematous, non-blistering
first-degree burn covering his entire anterior and posterior torso after a full day of sun
exposure. To accurately estimate and document the total body surface area (TBSA)
,affected using the Rule of Palms method, what percentage of the patient's total body
surface area does the patient’s own palm equal?
A. 0.5%
B. 1%
C. 3%
D. 4.5%
Answer: B. 1%
Rationale: The Rule of Palms (or Palm Method) is a standardized burn management
estimation tool where the size of the patient’s entire hand (including the palmar surface
and fingers) corresponds to roughly 1% of their total body surface area. It is highly
useful for measuring scattered, irregular, or localized first- and second-degree burns.
Question 3
An adult female patient presents to the clinic reporting clear nasal drainage, nasal
obstruction, a throbbing facial headache localized over the maxillary antrum, and
tenderness to palpation beneath her orbits. The nurse practitioner notes that the facial
pain radiates up toward her supraorbital region. Which diagnosis is most consistent with
this presentation?
A. Acute allergic rhinitis
B. Maxillary sinusitis
C. Trigeminal neuralgia
D. Cluster headache
Answer: B. Maxillary sinusitis
Rationale: Maxillary sinusitis characteristically manifests as throbbing facial pressure
and localized tenderness over the antrum (cheek area), often accompanied by nasal
congestion and clear or purulent nasal discharge. The pain frequently refers upwards to
the supraorbital area along branches of the trigeminal nerve as sinus pressure builds.
Question 4
A 65-year-old male patient with a history of heart failure with reduced ejection fraction
(HFrEF) presents for a routine evaluation. The nurse practitioner reviews his laboratory
trends and observes that a recently administered medication regimen has significantly
enhanced the activity of Gamma-Aminobutyric Acid (GABA) receptors. How will the
systemic utilization of GABA-agonizing drugs affect this patient’s seizure threshold?
,A. Decrease the seizure threshold
B. Increase the seizure threshold
C. Have no impact on the seizure threshold
D. Cause paradoxical status epilepticus
Answer: B. Increase the seizure threshold
Rationale: Gamma-Aminobutyric Acid (GABA) is the principal inhibitory neurotransmitter
within the mammalian central nervous system. GABA agonists enhance
hyperpolarization of the neuronal membranes, reducing overall central excitability. By
lowering neuronal firing, these medications effectively increase the seizure threshold,
making it harder for an abnormal electrical cascade to occur.
Question 5
A 45-year-old patient presents to the primary care clinic reporting irregular heart
palpitations, mild shortness of breath, and intermittent anxiety. During the physical
examination, the clinician auscultates premature atrial contractions (PACs). Which of
the following clinical actions represents a direct therapeutic intervention rather than an
assessment or diagnostic evaluation?
A. Palpating a radial pulse while simultaneously auscultating heart tones to identify a
pulse deficit
B. Ordering 2 Liters of oxygen via nasal cannula if the patient becomes acutely
symptomatic
C. Performing a comprehensive head-to-toe physical examination
D. Ordering a baseline 12-lead Electrocardiogram (EKG)
Answer: B. Ordering 2 Liters of oxygen via nasal cannula if the patient becomes
acutely symptomatic
Rationale: In clinical reasoning, it is essential to differentiate between assessment
actions and active interventions. Palpating a pulse, conducting a physical exam, and
ordering an EKG are diagnostic evaluation actions used to collect data. Administering
supplemental oxygen is an active therapeutic intervention designed to alter the patient's
immediate physiological status.
Question 6
A 54-year-old male patient with a history of severe persistent asthma presents to the
clinic for a follow-up. The nurse practitioner wishes to prescribe an oral medication that
acts as a leukotriene receptor antagonist (LTRA) to help manage his chronic airway
inflammation. Which of the following medications matches this pharmacological
mechanism?
, A. Albuterol
B. Fluticasone
C. Montelukast
D. Ipratropium
Answer: C. Montelukast
Rationale: Montelukast is an oral leukotriene receptor antagonist (LTRA) that blocks the
action of leukotrienes, which are potent inflammatory mediators released by mast cells
and eosinophils that induce bronchoconstriction and mucus production. Albuterol is a
beta2-agonist, fluticasone is a corticosteroid, and ipratropium is an anticholinergic.
Question 7
A 62-year-old female with type 2 diabetes presents complaining of pain, numbness, and
a burning sensation in both feet that is worse at night. On examination, the clinician
notes decreased sensation to light touch and vibratory sensation in a symmetrical
"stocking" distribution. Which condition does this match?
A. Peripheral arterial disease
B. Diabetic peripheral neuropathy
C. Chronic venous insufficiency
D. Lumbar radiculopathy
Answer: B. Diabetic peripheral neuropathy
Rationale: Diabetic peripheral neuropathy typically presents as a symmetrical distal
polyneuropathy, often described as a "stocking-glove" pattern. It primarily results from
microvascular damage to peripheral nerves secondary to chronic hyperglycemia,
presenting with sensory loss, burning pain, and paresthesias.
Question 8
A 35-year-old patient presents with chronic, recurrent abdominal pain that is relieved by
defecation. The patient reports that the pain is associated with changes in stool
frequency and consistency, alternating between diarrhea and constipation over the last
6 months. Stool cultures, colonoscopy, and basic labs are all normal. What is the most
likely diagnosis?
A. Crohn's disease
B. Ulcerative colitis
C. Irritable Bowel Syndrome (IBS)
D. Celiac disease
