ADVANCED PHARMACOLOGY, ADVANCED PHYSICAL ASSESSMENT,
CLINICAL DECISION-MAKING, DIAGNOSTIC REASONING, AND
EVIDENCE-BASED PRACTICE FOR THE NURSE PRACTITIONER
CERTIFICATION EXAM.
Question 1: A 65-year-old male with a history of coronary artery disease presents
with acute onset of severe, substernal chest pain radiating to his left arm,
accompanied by diaphoresis and nausea. An ECG reveals ST-segment elevation in
leads V1-V4. Which of the following is the most appropriate immediate
management?
A. Administer sublingual nitroglycerin and schedule a stress test
B. Administer aspirin, oxygen, morphine, and arrange for emergent percutaneous
coronary intervention
C. Administer tissue plasminogen activator (tPA) and transfer to the ICU
D. Start a beta-blocker and order a cardiac catheterization for tomorrow
CORRECT ANSWER: B. Administer aspirin, oxygen, morphine, and arrange for
emergent percutaneous coronary intervention.
Rationale: This patient is experiencing an acute ST-segment elevation myocardial
infarction (STEMI). The immediate management includes aspirin, oxygen,
morphine for pain, and emergent reperfusion therapy, preferably with
percutaneous coronary intervention (PCI). Time is muscle, and door-to-balloon
,time should be less than 90 minutes. Thrombolytics are an alternative if PCI is not
available, but PCI is preferred.
Question 2: A 72-year-old female presents with a 3-day history of progressive
confusion, fever, and cough. She has a history of dementia and lives in a nursing
home. On examination, she is febrile with crackles at the right lung base. Which of
the following is the most likely causative organism?
A. Streptococcus pneumoniae
B. Mycoplasma pneumoniae
C. Legionella pneumophila
D. Chlamydophila pneumoniae
CORRECT ANSWER: A. Streptococcus pneumoniae.
Rationale: In elderly patients, particularly those in nursing homes, community-
acquired pneumonia is most commonly caused by Streptococcus pneumoniae.
The presentation with fever, cough, and focal crackles is classic. Atypical organisms
like Mycoplasma and Chlamydophila are more common in younger patients.
Legionella is associated with water sources and tends to present with
gastrointestinal symptoms.
Question 3: A 45-year-old male presents with a painful, swollen right knee after
twisting his ankle while playing basketball. On examination, there is joint effusion
and erythema. Aspiration reveals yellow, turbid fluid with a white blood cell count
,of 75,000/mm³ and Gram-positive cocci in clusters. Which of the following is the
most appropriate empiric antibiotic therapy?
A. Ceftriaxone
B. Vancomycin
C. Ciprofloxacin
D. Doxycycline
CORRECT ANSWER: B. Vancomycin.
Rationale: Septic arthritis is a medical emergency. The presence of Gram-positive
cocci in clusters suggests Staphylococcus aureus, which is the most common cause
of septic arthritis in adults. Given the increasing prevalence of methicillin-resistant
S. aureus (MRSA), empiric vancomycin is the preferred initial antibiotic.
Ceftriaxone would be appropriate for suspected gonococcal arthritis.
Question 4: A 58-year-old male with a history of hypertension and hyperlipidemia
presents with a sudden onset of severe headache, described as "the worst
headache of my life." He reports nausea and vomiting. Neurological examination
is non-focal. Which of the following is the most appropriate initial diagnostic test?
A. Lumbar puncture
B. CT scan of the head without contrast
C. MRI of the brain with contrast
D. Carotid ultrasound
CORRECT ANSWER: B. CT scan of the head without contrast.
, Rationale: A "thunderclap" headache is the classic presentation of subarachnoid
hemorrhage. A non-contrast CT scan of the head is the initial diagnostic test of
choice, with a sensitivity of approximately 95-98% within the first 24 hours. If the
CT is negative, a lumbar puncture should be performed to look for xanthochromia.
MRI is not the first-line test for acute subarachnoid hemorrhage.
Question 5: A 34-year-old female presents with a 2-week history of joint pain,
malar rash, and photosensitivity. She reports intermittent fevers and fatigue.
Laboratory studies reveal positive antinuclear antibodies and anti-dsDNA
antibodies. Which of the following is the most appropriate initial treatment?
A. Hydroxychloroquine and NSAIDs
B. Prednisone 60 mg daily
C. Methotrexate
D. Cyclophosphamide
CORRECT ANSWER: A. Hydroxychloroquine and NSAIDs.
Rationale: This patient presents with classic features of systemic lupus
erythematosus (SLE): malar rash, photosensitivity, arthritis, and positive
serologies. For mild to moderate disease without major organ involvement,
hydroxychloroquine and NSAIDs are first-line therapy. High-dose corticosteroids
and immunosuppressants are reserved for severe disease with renal or neurologic
involvement.
