,NURS 5315 | FINAL EXAM | PRACTICE SET
Section 1: Brief Introduction
This 150-question NURS 5315 final-exam practice set integrates advanced pathophysiology,
pharmacology, health assessment, and clinical reasoning across the lifespan. It covers cellular
function and immunity; cardiovascular, respiratory, endocrine/metabolic, renal,
gastrointestinal, neurologic, and musculoskeletal systems; evidence-based practice; and
professional-role considerations.
Section 2: The Complete Exam
Select the single best response. Each keyed answer and rationale follows the item. The exam mixes application,
prioritization, pathophysiology, pharmacology, and advanced assessment across major systems.
1. During prolonged myocardial ischemia, intracellular ATP falls and the sodium-potassium
pump fails. Which early cellular change is expected?
A. Increased oxidative phosphorylation and ATP synthesis.
B. Immediate lysosomal enzyme activation with complete membrane rupture.
C. Intracellular sodium and water accumulation causing cell swelling.
D. Selective loss of nuclear DNA without cytoplasmic change.
Rationale: ATP depletion impairs energy-dependent ion pumps, allowing sodium and water to
accumulate in the cell. Reversible cell swelling precedes irreversible membrane injury if oxygen
delivery is restored.
2. A biopsy shows scattered cells with shrinkage, chromatin condensation, and membrane-
bound apoptotic bodies, without surrounding inflammation. Which process best explains this
finding?
A. Programmed apoptosis with orderly caspase-mediated cell removal.
B. Caseous necrosis from granulomatous infection.
C. Coagulative necrosis from ischemia.
D. Liquefactive necrosis from enzymatic digestion.
Rationale: Apoptosis is regulated cell death with cell shrinkage and apoptotic bodies that are
cleared with little inflammation. Necrosis usually involves membrane disruption and leakage
of intracellular contents.
3. A patient with atherosclerotic plaque rupture has an intense local inflammatory response.
Which innate immune sensor can activate caspase-1 and promote maturation of interleukin-1
beta?
A. The sodium-glucose cotransporter 2.
B. The nuclear estrogen receptor.
C. The T-cell receptor complex.
D. The NLRP3 inflammasome.
Rationale: NLRP3 is an intracellular pattern-recognition platform that can activate caspase-1
and process pro-IL-1 beta and pro-IL-18. This links cellular danger signals to innate
inflammation and is implicated in atherosclerotic disease.

4. A patient with bacterial pneumonia develops fever and an elevated C-reactive protein. Which
mechanism most directly drives hepatic CRP production?
A. Direct conversion of CRP into immunoglobulin by B cells.
B. Interleukin-6 signaling to hepatocytes during the acute-phase response.
C. Insulin binding to hepatic insulin receptors.
D. Acetylcholine release at the neuromuscular junction.
Rationale: IL-6 is a major cytokine driving hepatic acute-phase protein synthesis, including
CRP. CRP is a nonspecific marker of inflammation and must be interpreted with the clinical
picture.
5. A patient with recurrent Neisseria infections has deficient C5 through C9. Which host-defense
function is impaired?
A. IgE-mediated mast-cell degranulation.
B. Opsonization through C3b deposition only.
C. Formation of the membrane attack complex that lyses susceptible bacteria.
D. Antigen presentation by major histocompatibility complex class II.
Rationale: Terminal complement components C5b through C9 assemble the membrane attack
complex, which is particularly important against Neisseria. C3b opsonization is mediated
earlier in the complement cascade.
6. A patient develops urticaria, wheezing, and hypotension within minutes of a bee sting. Which
immune mechanism is most likely?
A. CD8-positive T-cell cytotoxicity without antibody involvement.
B. Immune-complex deposition developing over several days.
C. IgG-mediated red-cell destruction by complement.
D. Immediate IgE-mediated mast-cell degranulation with release of histamine and other
mediators.
Rationale: Type I hypersensitivity occurs when allergen cross-links IgE bound to mast cells,
causing rapid mediator release and systemic symptoms. Anaphylaxis requires immediate
intramuscular epinephrine and airway/circulatory support.
7. A patient develops fever, arthralgia, and a rash one week after receiving a foreign antiserum.
Which mechanism best explains this delayed systemic reaction?
A. Type IV hypersensitivity from isolated delayed T-cell contact dermatitis.
B. Type II hypersensitivity from antibody binding a fixed cell-surface antigen.
C. Type III hypersensitivity from circulating antigen-antibody immune-complex
deposition.
D. Type I hypersensitivity from immediate IgE cross-linking.
Rationale: Serum sickness is a type III reaction in which soluble immune complexes deposit in
tissues and activate complement. The delayed onset and multisystem inflammatory symptoms
distinguish it from immediate IgE-mediated allergy.

8. A patient develops an eczematous rash 48 hours after nickel exposure. Which immunologic
pathway is most likely?
A. Delayed type IV hypersensitivity mediated by sensitized T lymphocytes.
B. Immune-complex deposition in glomeruli.
C. IgE-mediated mast-cell degranulation within minutes.
D. Autoantibody-mediated platelet destruction.
Rationale: Allergic contact dermatitis is a type IV delayed hypersensitivity response driven by
antigen-specific T cells and cytokines. It typically appears hours to days after exposure rather
than immediately.
9. A patient with systemic lupus erythematosus has low C3 and C4 during a nephritic flare.
Which process best explains complement consumption?
A. Immune-complex deposition activates the classical complement pathway.
B. Isolated IgE activation of mast cells uses all circulating C3 and C4.
C. Excess production of erythropoietin consumes complement.
D. The kidney stops synthesizing complement because glomerular filtration falls.
Rationale: SLE immune complexes can deposit in tissues and activate the classical
complement pathway, lowering circulating C3 and C4. Complement levels can help assess
activity but do not replace clinical evaluation and urine testing.
10. After a medication exposure, a patient develops diffuse hives, bronchospasm, and shock.
Which mediator effect contributes most to the acute vasodilation and increased vascular
permeability?
A. Increased aldosterone secretion from the adrenal cortex.
B. Histamine release from activated mast cells and basophils.
C. Suppression of leukotriene synthesis in the airways.
D. Reduced nitric oxide production in vascular endothelium.
Rationale: Histamine and other mast-cell mediators cause vasodilation, capillary leak, and
bronchoconstriction in anaphylaxis. Intramuscular epinephrine is first-line because it reverses
airway edema, bronchospasm, and vasodilation.
11. A patient with acute coronary syndrome has a CYP2C19 poor-metabolizer result while
taking clopidogrel. Which pharmacologic concern is most relevant?
A. The genotype proves resistance to aspirin as well.
B. Enhanced CYP2C19 activity causing predictable hemorrhage.
C. Increased conversion of clopidogrel into a direct thrombin inhibitor.
D. Reduced formation of clopidogrel's active metabolite may weaken platelet inhibition.
Rationale: Clopidogrel is a prodrug that requires CYP2C19-dependent activation, so poor
metabolizers may have reduced platelet inhibition. For high-risk indications, an alternative
P2Y12 inhibitor may be considered when clinically appropriate (CPIC, 2022).
