A patient has endured several dosage adjustments of his tricyclic anti-
depressant, so the provider recommends genetic testing. Which statement
correctly describes the rationale for genetic testing?
a. The CYP2D6 gene influences metabolism of tricyclic antidepressants and
certain other drugs
b. The HER2 gene is a tumor marker that impacts metabolism of tricyclic
antidepressants
c. The BRCA2 gene influences metabolism of certain drugs and increases the
risk for breast cancer
d. The x-linked OPN1MW gene for male color blindness also slows metabolism
of certain drugs: a. The CYP2D6 gene influences metabolism of tricyclic antide-
pressants and certain other drugs
Answer/Rationale: CYP2D6 - page 155 Box 4.3 of Chapter 4 Genes and Genetic Dis-
eases, McCance & Huether, Unit 2, Genes, Environmental Lifestyle, and Common
Diseases. HER2 is a gene often implicated with cancer, as is BRCA2. OPN1MW is
the gene that codes for color blindness in men. Metabolism of 25% of all prescribed
drugs, including tricyclic antidepressants, beta adrenergic receptor blockers, and
neuroleptics, is influenced by variants in a certain gene, requiring genetic testing to
reduce trial-and-error in estimating appropriate drug-dosage levels.
2. As an advanced practice nurse, you want to learn more about the CDC's
initiatives relative to asthma care and management in order to advocate for
asthma sufferers at the state legislative level. Your goal is to reduce medica-
tions costs to patients. Which CDC recommendation supports your goal?
a. The CDC recommends that payers and employers promote healthy work-
spaces to decrease environmental trigger exposures
b. The CDC recommends that providers prescribe the most cost-efficient
1 N/ N48
, long-acting inhalers to lower patient co-pays
c. The CDC recommends that providers deviate from the stepwise approach
to lessen the financial impact to the patient
d. The CDC recommends that co-pays be removed for inhaled corticosteroids
and other prescribed medications: d. The CDC recommends that co-pays be
removed for inhaled corticosteroids and other prescribed medications
3. Answer/Rationale: D - The CDC recommends that co-pays be removed for
epressant, so the provider recommends genetic testing. Which statement
correctly describes the rationale for genetic testing?
a. The CYP2D6 gene influences metabolism of tricyclic antidepressants and
certain other drugs
b. The HER2 gene is a tumor marker that impacts metabolism of tricyclic
antidepressants
c. The BRCA2 gene influences metabolism of certain drugs and increases the
risk for breast cancer
