NUR 612 Exam 2026/2027
Complete Exam with Answers and Rationales
Section 1: Brief Introduction
NUR 612 is a graduate-level advanced practice nursing course covering the science that
underpins clinical judgment across all four APRN roles. This 100-question examination
spans advanced pathophysiology across the lifespan, including genetic and genomic
considerations and multisystem interactions; advanced pharmacology, including
pharmacokinetics, pharmacodynamics, drug interactions, and prescribing for complex and
older adults; advanced health assessment, differential diagnosis, and clinical reasoning;
evidence-based practice and quality improvement; and the ethical, legal, regulatory, and
interprofessional dimensions of the advanced practice role.
Note on course numbering and currency. The course code NUR 612 is not standardized
across schools of nursing; different institutions assign it to advanced pathophysiology,
advanced health assessment, or advanced practice nursing II, so no single institutional
blueprint or item bank exists for it. This examination is therefore built to the AACN Essentials
advanced-level competencies and the three graduate APRN core sciences rather than to any
one school's syllabus, and it is a study and self-assessment instrument rather than a copy of
a proctored institutional exam. Clinical content reflects guidance current as of mid-2026,
including the 2025 AHA/ACC hypertension guideline, the 2026 ADA Standards of Care, the
2026 GOLD report, KDIGO 2024, and the 2023 AGS Beers Criteria; always verify against the
most recent guideline and your program's assigned references.

Section 2: The Complete Exam
1. A nurse practitioner student is asked to distinguish apoptosis from necrosis.
Which statement is correct?
A. Apoptosis results from acute cellular swelling and membrane rupture
B. Necrosis is regulated by caspase activation and conserves ATP
C. Necrosis affects single cells while apoptosis always affects tissue fields
D. Apoptosis is an energy-dependent, programmed process that does not
provoke an inflammatory response
Rationale: Apoptosis uses ATP-dependent caspase cascades and packages cellular contents
into membrane-bound bodies cleared by phagocytes, so no inflammation occurs. Necrosis is
the pathologic, passive process featuring cell swelling, membrane rupture, and release of
contents that triggers inflammation.
2. A patient with long-standing hypertension has echocardiographic left ventricular
wall thickening. This cellular adaptation is:
A. Hyperplasia, an increase in the number of myocytes
B. Metaplasia, replacement of myocytes with fibroblasts
C. Hypertrophy, an increase in the size of individual myocytes
D. Dysplasia, disordered myocyte maturation
Rationale: Cardiac myocytes are permanent cells that cannot divide, so they respond to
chronic pressure overload by enlarging rather than proliferating. Hyperplasia is impossible in
permanent tissue, and metaplasia and dysplasia describe epithelial changes, not a physiologic
response to afterload.
3. In the earliest reversible phase of hypoxic cell injury, cellular swelling occurs
primarily because:
A. Lysosomal enzymes are released into the cytoplasm
B. ATP depletion impairs the sodium-potassium ATPase, allowing sodium and
water to accumulate intracellularly
C. Calcium is actively pumped out of the mitochondria
D. Protein synthesis on the rough endoplasmic reticulum accelerates
Rationale: Loss of oxidative phosphorylation halts ATP production, and without the sodium
pump the cell cannot extrude sodium, drawing in water. Lysosomal rupture and massive
calcium influx are late, irreversible events rather than the initiating mechanism.

4. Reperfusion injury after restoration of blood flow to ischemic tissue is largely
mediated by:
A. Sudden depletion of intracellular calcium
B. Immediate restoration of normal mitochondrial function
C. Generation of reactive oxygen species that peroxidize membrane lipids and
damage DNA
D. Decreased leukocyte recruitment to the injured area
Rationale: Reintroduced oxygen is converted to superoxide and hydroxyl radicals by
damaged mitochondria and infiltrating neutrophils, causing lipid peroxidation and DNA
strand breaks. Calcium actually rises rather than falls, and leukocyte recruitment increases,
compounding the injury.
5. Barrett esophagus, in which squamous epithelium is replaced by columnar
epithelium, is an example of:
A. Anaplasia, complete loss of differentiation
B. Metaplasia, a reversible substitution of one differentiated cell type for another
C. Hypertrophy of the esophageal mucosa
D. Coagulative necrosis of the distal esophagus
Rationale: Chronic acid exposure causes reserve cells to differentiate along a more acid-
resistant columnar line, which is metaplasia and is potentially reversible. Anaplasia denotes
malignancy, and neither hypertrophy nor coagulative necrosis describes a change in cell type.
6. Which finding best distinguishes dysplasia from metaplasia on histologic review?
A. Dysplasia is always irreversible and constitutes invasive cancer
B. Metaplasia involves loss of the basement membrane
C. Dysplasia shows disordered growth with variation in cell size, shape, and
nuclear characteristics
D. Metaplasia is confined to mesenchymal tissue
Rationale: Dysplasia is atypical, disordered but non-invasive proliferation with
pleomorphism and increased nuclear-to-cytoplasmic ratio, and it can regress if the stimulus is
removed. Breach of the basement membrane defines invasive carcinoma, not metaplasia.
7. The immediate vasodilation and increased vascular permeability of acute
inflammation are most directly produced by:
A. Histamine released from mast cell granules acting on postcapillary venules
B. Interferon-gamma released from natural killer cells
C. Fibroblast deposition of type I collagen
D. Complement-independent T-cell activation
