Introduction
This comprehensive examination is designed to assess the advanced
practice nursing student's readiness for certification through the APEA
Predictor Exam. It evaluates the understanding of advanced
pathophysiology, pharmacology, clinical assessment, and diagnostic
reasoning across major body systems. The exam utilizes a multiple-choice
format with scenario-based questions that reflect real-world primary care
clinical situations and align with certification exam blueprints. Emphasis is
placed on the application of evidence-based clinical guidelines,
differential diagnosis, therapeutic management, and patient-centered care
across acute and chronic conditions. This assessment serves as a predictor
of success on the Chamberlain University NR603 APEA Predictor Exam and
helps identify areas for focused review. The following 100 questions are
organized into ten core domains aligned with the official NR603 course
competencies and the APEA exam blueprint. Each question includes the
,correct answer and a detailed rationale to enhance clinical reasoning and
reinforce advanced practice concepts.
SECTION ONE: QUESTIONS 1 – 100
DOMAIN 1: CARDIOVASCULAR SYSTEM ASSESSMENT AND
MANAGEMENT (Questions 1–15)
1. A 65-year-old male with a history of hypertension and type 2
diabetes presents with a 2-week history of progressive weakness in
his right arm and leg, along with difficulty finding words during
conversation. His symptoms are most pronounced in the morning
and improve slightly as the day progresses. A non-contrast head CT
is normal. What is the most appropriate next step?
A. Administer IV tPA immediately
B. Obtain an MRI of the brain with diffusion-weighted imaging
C. Start aspirin 325 mg daily
D. Refer for carotid endarterectomy
B. Obtain an MRI of the brain with diffusion-weighted imaging
RATIONALE: The clinical presentation of unilateral weakness and
expressive aphasia that fluctuates suggests a transient ischemic attack
(TIA) or an acute ischemic stroke. A normal non-contrast head CT within
the first 24 hours does not rule out an acute infarction, as early ischemic
changes may not be visible. Diffusion-weighted imaging (DWI) on MRI is
the most sensitive modality for detecting acute ischemic stroke within
minutes of onset. IV tPA (A) requires confirmation of stroke and
exclusion of hemorrhage. Aspirin (C) is appropriate for secondary
prevention but not the immediate diagnostic next step. Carotid
endarterectomy (D) is a surgical intervention for significant carotid
stenosis, which would be evaluated only after imaging confirms the
diagnosis and etiology.
,2. A 55-year-old female presents with acute onset of severe, tearing
chest pain radiating to the back. Blood pressure is 160/90 mm Hg in
the right arm and 100/60 mm Hg in the left arm. What is the most
likely diagnosis?
A. Acute myocardial infarction
B. Pulmonary embolism
C. Aortic dissection
D. Pericarditis
C. Aortic dissection
RATIONALE: The classic presentation of aortic dissection includes
severe, tearing chest pain radiating to the back, often with a pulse
deficit or blood pressure discrepancy between the arms. It is a life-
threatening emergency requiring immediate imaging and surgical
consultation.
3. During a cardiac exam, a holosystolic murmur is heard at the
apex with radiation to the axilla. This is most consistent with:
A. Aortic stenosis
B. Mitral regurgitation
C. Tricuspid regurgitation
D. Ventricular septal defect
B. Mitral regurgitation
RATIONALE: Mitral regurgitation causes a holosystolic murmur at the
apex that radiates to the axilla. Aortic stenosis is a systolic ejection
murmur at the right upper sternal border. Tricuspid regurgitation is a
holosystolic murmur at the left lower sternal border that increases with
inspiration (Carvallo's sign).
4. A patient with a history of heart failure presents with jugular
venous distention, peripheral edema, and hepatomegaly. These
findings are most consistent with:
A. Left-sided heart failure
B. Right-sided heart failure
, C. Pulmonary hypertension
D. Pericarditis
B. Right-sided heart failure
RATIONALE: Jugular venous distention, peripheral edema, and
hepatomegaly are signs of right-sided heart failure due to increased
systemic venous pressure. Left-sided heart failure presents with
pulmonary congestion (dyspnea, crackles, orthopnea). An enlarged
liver with a smooth, tender edge may suggest right-sided heart failure
or hepatic congestion.
5. A 68-year-old patient with a history of coronary artery disease
reports chest pain that occurs with exertion and is relieved by rest
or nitroglycerin. This is best described as:
A. Unstable angina
B. Stable angina
C. Variant (Prinzmetal's) angina
D. Myocardial infarction
B. Stable angina
RATIONALE: Stable angina is characterized by chest pain that is
predictable, occurs with exertion or stress, and is relieved by rest or
nitroglycerin. Unstable angina occurs at rest or with minimal exertion
and is a medical emergency.
6. A 72-year-old man with a history of benign prostatic hyperplasia
presents with acute urinary retention and suprapubic pain. He has a
distended bladder on palpation. Which of the following is the most
appropriate immediate intervention?
A. Prescribe tamsulosin
B. Perform a urethral catheterization
C. Schedule a transurethral resection of the prostate
D. Order a serum PSA level
B. Perform a urethral catheterization
