Introduction
This comprehensive predictor examination is designed to evaluate the
advanced practice registered nurse's (APRN) readiness for clinical practice
across the three P's: pathophysiology, pharmacology, and physical
assessment. The assessment integrates foundational scientific knowledge
with applied clinical reasoning, emphasizing the synthesis of patient data
to formulate accurate differential diagnoses and evidence-based treatment
plans. Each question reflects real-world clinical scenarios, challenging the
examinee to apply critical thinking, interpret diagnostic findings, and
make sound clinical decisions while adhering to professional and ethical
standards. Mastery of these domains is essential for safe, competent, and
autonomous advanced nursing practice.
,SECTION ONE: QUESTIONS 1–100
Question 1
A 68-year-old male presents with a 3-month history of progressive lower
back pain, unintentional weight loss of 15 pounds, and fatigue.
Laboratory findings reveal anemia, hypercalcemia, and elevated serum
creatinine. Which diagnostic test is MOST appropriate to confirm the
suspected diagnosis?
A. Serum protein electrophoresis
B. Bone scan
C. Serum prostate-specific antigen (PSA)
D. Complete blood count with differential
A
RATIONALE: This patient's presentation of back pain, weight loss,
anemia, hypercalcemia, and renal insufficiency is highly suggestive of
multiple myeloma. Serum protein electrophoresis with immunofixation
is the diagnostic test of choice to detect monoclonal gammopathy.
Question 2
A 55-year-old female with a history of hypertension and type 2 diabetes
mellitus presents with a 2-day history of right-sided facial droop,
difficulty speaking, and mild left arm weakness. Symptoms began 4
hours ago. A non-contrast head CT shows no evidence of hemorrhage.
Which intervention is MOST appropriate at this time?
A. Administer intravenous tissue plasminogen activator (tPA)
B. Administer aspirin 325 mg orally
C. Perform carotid endarterectomy
D. Administer heparin infusion
A
, RATIONALE: This patient presents with acute ischemic stroke
symptoms within the 4.5-hour window for intravenous tPA
administration. The absence of hemorrhage on CT makes tPA
appropriate. Time from symptom onset is critical; tPA should be
administered as soon as possible.
Question 3
A 72-year-old male with a history of coronary artery disease presents
with worsening shortness of breath, orthopnea, and paroxysmal
nocturnal dyspnea. Physical examination reveals jugular venous
distension, crackles in the lung bases, and 2+ pitting edema in the lower
extremities. An echocardiogram shows an ejection fraction of 30%.
Which medication is CONTRAINDICATED in this patient?
A. Lisinopril
B. Furosemide
C. Metoprolol succinate
D. Ibuprofen
D
RATIONALE: Ibuprofen is a nonsteroidal anti-inflammatory drug
(NSAID) that is contraindicated in heart failure with reduced ejection
fraction. NSAIDs cause sodium and water retention, increase systemic
vascular resistance, and reduce the effectiveness of diuretics and ACE
inhibitors.
Question 4
A 45-year-old female presents with a 6-month history of intermittent
episodes of palpitations, diaphoresis, headache, and anxiety. Blood
pressure during an episode is 190/110 mmHg. Which laboratory finding
is MOST consistent with the suspected diagnosis?
A. Elevated serum cortisol
B. Elevated plasma metanephrines
, C. Elevated serum aldosterone
D. Elevated serum thyroid-stimulating hormone (TSH)
B
RATIONALE: This presentation is classic for pheochromocytoma, a
catecholamine-secreting tumor of the adrenal medulla. Elevated plasma
metanephrines and normetanephrines are the most sensitive and
specific tests for diagnosis.
Question 5
A 60-year-old male with a history of chronic alcohol use presents with
confusion, jaundice, and ascites. Laboratory findings reveal elevated
liver enzymes, elevated bilirubin, and prolonged prothrombin time.
Which finding on physical examination is MOST suggestive of portal
hypertension?
A. Spider angiomas
B. Palmar erythema
C. Caput medusae
D. Gynecomastia
C
RATIONALE: Caput medusae is the dilation of the umbilical and
periumbilical veins, visible as a network of veins radiating from the
umbilicus. It is a classic sign of portal hypertension resulting from liver
cirrhosis.
Question 6
A 52-year-old female presents with a 4-week history of progressive
muscle weakness, difficulty swallowing, and a heliotrope rash on her
eyelids. She also reports difficulty rising from a seated position. Which
antibody is MOST likely to be positive in this patient?
A. Anti-Jo-1 antibody
B. Anti-Scl-70 antibody
