INTRODUCTION
This comprehensive pre-diagnostic practice examination is designed to rigorously assess the foundational and applied
knowledge essential for advanced nursing practice. The exam evaluates your understanding of key concepts across core
domains, including advanced health assessment, pathophysiology, pharmacology, professional ethics, and healthcare
policy. Through a blend of theoretical multiple-choice questions and complex, real-world scenario-based inquiries, this
assessment emphasizes the critical thinking and clinical decision-making skills necessary for safe and effective patient
,care. Success on this exam demonstrates a readiness to apply evidence-based practice and professional standards in
diverse clinical settings, ensuring you are well-prepared to navigate the complexities of modern healthcare.
SECTION ONE: QUESTIONS 1 – 50
1. A 45-year-old patient with a history of hypertension presents with a new onset of a throbbing, unilateral
headache accompanied by photophobia and nausea. Which of the following is the most appropriate initial
diagnostic step to differentiate this headache from a potential subarachnoid hemorrhage?
A. Order a non-contrast computed tomography (CT) scan of the head.
B. Administer a triptan medication to see if the headache resolves.
C. Perform a thorough neurological examination including fundoscopy.
D. Obtain a complete blood count and erythrocyte sedimentation rate.
🟢 Correct Answer: A. Order a non-contrast computed tomography (CT) scan of the head.
🔴 Explanation: A non-contrast CT scan of the head is the initial diagnostic test of choice to rule out subarachnoid
hemorrhage, as it is highly sensitive for acute blood in the subarachnoid space. While a neurological exam is
important, it is not the primary diagnostic step for differentiation. Administering medication without a diagnosis or
ordering non-specific labs is not appropriate.
,2. A patient is prescribed a new medication that is a high-affinity beta-1 adrenergic receptor antagonist. Which
physiological effect is most directly associated with this drug's mechanism of action?
A. Bronchodilation
B. Increased heart rate
C. Decreased myocardial contractility
D. Peripheral vasodilation
🟢 Correct Answer: C. Decreased myocardial contractility
🔴 Explanation: Beta-1 adrenergic receptors are primarily located in the heart. Antagonism of these receptors leads
to a decrease in heart rate (negative chronotropy) and a decrease in the force of contraction (negative inotropy),
which ultimately decreases myocardial contractility. Bronchodilation is associated with beta-2 agonism, and
peripheral vasodilation is not a direct effect of beta-1 antagonism.
3. A 6-month-old infant presents with failure to thrive, recurrent respiratory infections, and a palpable, non-
pulsatile mass in the left upper quadrant of the abdomen. Which diagnostic test is most likely to confirm the
suspected diagnosis?
A. Upper gastrointestinal series with small bowel follow-through
B. Abdominal ultrasound
, C. Serum alpha-fetoprotein (AFP) level
D. Stool analysis for reducing substances
🟢 Correct Answer: B. Abdominal ultrasound
🔴 Explanation: The combination of failure to thrive, recurrent infections, and a left upper quadrant abdominal mass
is highly suggestive of a Wilms' tumor (nephroblastoma). An abdominal ultrasound is the initial imaging modality of
choice to visualize a renal mass. While an upper GI series could rule out other issues, ultrasound is specific for
evaluating the kidneys. AFP is more associated with hepatoblastoma.
4. According to the principles of evidence-based practice, which of the following sources of evidence is
considered the highest level of evidence for guiding clinical decision-making?
A. A well-designed randomized controlled trial (RCT)
B. A systematic review and meta-analysis of RCTs
C. A single, large, prospective cohort study
D. An expert opinion from a clinical specialist
🟢 Correct Answer: B. A systematic review and meta-analysis of RCTs
🔴 Explanation: In the hierarchy of evidence, a systematic review and meta-analysis that synthesizes results from
multiple high-quality randomized controlled trials provides the most robust and reliable evidence to guide clinical
