SECTION 1: Foundations of FNP Practice & Advanced Pathophysiology (Q1-Q20)
Q1: A 45-year-old patient presents with a chronic wound that has not healed after 4
weeks. The FNP recognizes that which cellular adaptation is most likely occurring at the
wound margin?
A. Hyperplasia [CORRECT]
B. Metaplasia
C. Dysplasia
D. Anaplasia
Correct Answer: A
Rationale: Hyperplasia is an increase in cell number that occurs in response to injury or
stress to facilitate tissue repair and wound healing. Metaplasia involves reversible
replacement of one differentiated cell type with another, dysplasia represents
disordered growth with loss of cellular uniformity, and anaplasia indicates loss of
differentiation characteristic of malignancy, none of which are the primary adaptive
response in wound healing.
Q2: During a wellness visit, a 28-year-old patient asks about the FNP's scope of practice
in Texas. Which statement best describes the autonomous practice authority of an FNP
in Texas?
A. FNPs in Texas have full independent practice authority without physician
collaboration after a transition to practice period [CORRECT]
B. FNPs must maintain continuous on-site physician supervision at all times
C. FNPs in Texas cannot prescribe Schedule II controlled substances under any
circumstances
D. FNPs are limited to performing only well-child examinations and health screenings
Correct Answer: A
Rationale: Under Texas law, FNPs who have completed their transition to practice period
(minimum 2 years or 4,000 hours of practice under a physician's delegation) may
,practice independently without continuous physician supervision. FNPs do have
prescribing authority for Schedule II-V controlled substances with proper DEA
registration, and their scope extends far beyond well-child visits to include
comprehensive primary care across the lifespan.
Q3: A patient with a bacterial infection develops fever and elevated white blood cell
count. Which inflammatory mediator is primarily responsible for the pyrogenic
response?
A. Interleukin-1 (IL-1) [CORRECT]
B. Interleukin-4 (IL-4)
C. Interleukin-10 (IL-10)
D. Transforming growth factor-beta (TGF-β)
Correct Answer: A
Rationale: Interleukin-1 (IL-1) is a primary endogenous pyrogen that acts on the
hypothalamic thermoregulatory center to induce fever during the acute inflammatory
response. IL-4 promotes Th2 differentiation and B-cell activation, IL-10 is an
anti-inflammatory cytokine, and TGF-β is involved in tissue repair and immune
suppression, none of which directly mediate the febrile response.
Q4: A 60-year-old male with a 40 pack-year smoking history presents with a new cough
and hemoptysis. Chest CT reveals a 3 cm spiculated mass in the right upper lobe.
Which genetic mutation is most commonly associated with this type of malignancy?
A. KRAS mutation [CORRECT]
B. BRAF V600E mutation
C. JAK2 V617F mutation
D. Philadelphia chromosome (BCR-ABL)
Correct Answer: A
Rationale: KRAS mutations are the most common oncogenic driver mutations in
non-small cell lung cancer, particularly in smoking-related adenocarcinomas, occurring
in approximately 25-30% of cases. BRAF V600E is seen in melanoma and some lung
cancers but less commonly than KRAS, JAK2 V617F is characteristic of
myeloproliferative neoplasms, and the Philadelphia chromosome is diagnostic of
chronic myeloid leukemia.
,Q5: A patient with type 2 diabetes mellitus has poor glycemic control despite lifestyle
modifications. The FNP recognizes that insulin resistance at the cellular level is
primarily mediated by which pathophysiological mechanism?
A. Downregulation of insulin receptor substrate-1 (IRS-1) signaling and defective GLUT4
translocation [CORRECT]
B. Absolute destruction of pancreatic beta cells by autoimmune mechanisms
C. Excessive glucagon secretion due to alpha cell hyperplasia
D. Increased insulin receptor affinity and upregulation of tyrosine kinase activity
Correct Answer: A
Rationale: Type 2 diabetes mellitus is characterized by insulin resistance mediated
through post-receptor defects including impaired IRS-1 phosphorylation and defective
translocation of GLUT4 glucose transporters to the cell membrane. Absolute beta-cell
destruction is pathognomonic for type 1 diabetes, excessive glucagon contributes to
hyperglycemia but is not the primary mechanism of insulin resistance, and increased
receptor affinity would enhance rather than impair insulin sensitivity.
Q6: During a genetic counseling session, a 35-year-old female is found to carry a BRCA1
mutation. Which cancer prevention strategy is most strongly recommended by the
USPSTF for this patient?
A. Risk-reducing bilateral salpingo-oophorectomy by age 40-45 [CORRECT]
B. Annual chest X-ray beginning at age 30
C. Prophylactic total gastrectomy by age 35
D. Annual CA-125 testing without transvaginal ultrasound
Correct Answer: A
Rationale: The USPSTF recommends that women with BRCA1/2 mutations consider
risk-reducing bilateral salpingo-oophorectomy between ages 35-40 (or completion of
childbearing) to reduce ovarian cancer risk. Annual chest X-ray is not recommended for
breast cancer screening (MRI and mammography are preferred), prophylactic
gastrectomy is not indicated for BRCA1 carriers, and CA-125 alone is insufficient for
ovarian cancer surveillance.
Q7: A patient with chronic inflammation develops a wound that heals with excessive
collagen deposition, resulting in a raised scar extending beyond the original wound
boundaries. This represents which pathophysiological process?
, A. Keloid formation [CORRECT]
B. Hypertrophic scar
C. Contracture
D. Granulation tissue overgrowth
Correct Answer: A
Rationale: Keloids are characterized by excessive collagen deposition that extends
beyond the original wound margins due to dysregulated fibroblast activity and TGF-β
signaling. Hypertrophic scars remain confined to the original wound boundaries,
contractures involve scar tissue shortening across joints, and granulation tissue
overgrowth represents normal wound healing tissue that does not produce excessive
permanent scar.
Q8: An FNP is evaluating a patient with suspected Cushing syndrome. Which laboratory
finding is most consistent with the pathophysiology of this disorder?
A. Elevated 24-hour urinary free cortisol and loss of normal circadian cortisol rhythm
[CORRECT]
B. Decreased ACTH with elevated morning cortisol
C. Normal cortisol with elevated aldosterone
D. Decreased urinary free cortisol and elevated renin
Correct Answer: A
Rationale: Cushing syndrome is characterized by excessive cortisol production resulting
in elevated 24-hour urinary free cortisol and loss of the normal diurnal variation with
cortisol suppression at night. ACTH is typically elevated in pituitary Cushing disease
and suppressed in adrenal Cushing syndrome, normal cortisol rules out Cushing
syndrome, and decreased urinary free cortisol is inconsistent with hypercortisolism.
Q9: A patient with metastatic cancer is receiving chemotherapy. The FNP explains that
alkylating agents exert their cytotoxic effect primarily through which mechanism?
A. Cross-linking DNA strands and preventing replication [CORRECT]
B. Inhibiting topoisomerase II and preventing DNA unwinding
C. Stabilizing microtubules and preventing depolymerization
D. Competitively inhibiting estrogen receptors on tumor cells
Correct Answer: A
