A 45-year-old male is admitted for HF. His father died of SCD at 40; his sister has a pacemaker. A pedigree shows vertical transmission across three generations with both sexes affected. What is the most likely inheritance pattern and the AGACNP's next step?
Show answer →Autosomal Dominant (AD) inheritance. Key features: vertical transmission, approx. 50% risk for offspring, and males/females affected equally. Next step: Referral to a board-certified genetic counselor and screening of first-degree relatives. Clinical Pearl: Hypertrophic Cardiomyopathy (HCM) is often AD and a leading cause of SCD in young adults. ANCC Tip: Distinguish AD from Autosomal Recessive (horizontal transmission, 25% risk, skipped generations). Identifying red flags like early-onset disease or clusters of rare conditions is a core competency.
A patient with a recent DES for STEMI experiences stent thrombosis despite adherence to clopidogrel. Genetic testing reveals a CYP2C19*2 loss-of-function allele. How should the AGACNP modify the treatment plan based on current 2026 pharmacogenomic guidelines?
Show answer →Switch from clopidogrel to an alternative P2Y12 inhibitor, such as ticagrelor or prasugrel (if no contraindications). Rationale: Clopidogrel is a prodrug requiring activation by the CYP2C19 enzyme. Poor metabolizers (e.g., *2, *3 alleles) have reduced active metabolite levels, leading to higher rates of major adverse cardiovascular events (MACE). Exam Strategy: ANCC focuses on clinical application of genomic data. Distinguish between genotype (genetic makeup) and phenotype (observable trait/drug response). This is high-yield for acute care NPs managing post-PCI patients.
A 30-year-old patient expresses fear that testing positive for a BRCA1 mutation will cause her employer to terminate her health insurance. Which federal law provides protection in this scenario, and what are its primary limitations?
Show answer →Genetic Information Nondiscrimination Act (GINA) of 2008. GINA prohibits health insurers from using genetic information to determine eligibility or premiums and prohibits employers (with 15+ employees) from using genetic info in hiring/firing/promotion. LIMITATIONS: GINA does NOT apply to life insurance, disability insurance, or long-term care insurance. It also does not apply to members of the military or patients with symptomatic disease already diagnosed. ANCC Tip: Distinguish between genetic information (risk) and manifest disease (actual diagnosis).
A 52-year-old female is admitted for a bowel obstruction. Biopsy reveals colorectal cancer. Family history includes a mother with endometrial cancer at 45 and a brother with CRC at 48. What syndrome should the AGACNP suspect, and what is the screening recommendation?
Show answer →Lynch Syndrome (Hereditary Non-Polyposis Colorectal Cancer - HNPCC). Suspect when the 3-2-1 rule is met: 3 relatives with Lynch-associated cancers (CRC, endometrial, gastric, ovarian), 2 generations, 1 diagnosed before age 50. Recommendation: Genetic testing for mismatch repair (MMR) gene mutations (MLH1, MSH2, MSH6, PMS2). Clinical Pearl: Lynch is the most common cause of inherited CRC. AGACNPs must identify these high-risk patients for lifelong surveillance (colonoscopy every 1-2 years) and multidisciplinary management.
A 38-year-old female with no prior screening presents with a palpable breast mass. Her sister was diagnosed with breast cancer at 35 and her paternal aunt had ovarian cancer. What is the most appropriate AGACNP action regarding risk assessment?
Show answer →Perform a formal risk assessment using a validated tool (e.g., Gail Model or Tyrer-Cuzick) and refer to a genetic counselor for BRCA1/BRCA2 testing. Rationale: Early-onset breast cancer (<50) and the presence of ovarian cancer in a family lineage are high-yield indicators for hereditary breast and ovarian cancer (HBOC) syndrome. Exam Strategy: ANCC looks for the NP's role in secondary prevention and risk stratification. Note that paternal history is just as relevant as maternal history in autosomal dominant conditions; do not ignore the father's side of the family.
