What are some things that put the elderly patient at higher risk for adverse drug
reactions? -Correct Answers ✔-reduced renal function
polypharmacy (the use of five or more medications daily)
greater severity of illness
presence of comorbidities
use of drugs that have a low therapeutic index (e.g., digoxin)
increased individual variation secondary to altered pharmacokinetics
inadequate supervision of long-term therapy
poor patient adherence
How can healthcare providers decrease likelihood of an elderly patient
experiencing an adverse drug reaction? -Correct Answers ✔-obtaining a thorough
drug history that includes over-the-counter medications
considering pharmacokinetic and pharmacodynamics changes due to age
monitoring the patient's clinical response and plasma drug levels
using the simplest regimen possible
monitoring for drug-drug interactions and iatrogenic illness
periodically reviewing the need for continued drug therapy
encouraging the patient to dispose of old medications
taking steps to promote adherence and to avoid drugs on the Beers list
How can we promote medication adherence with elderly patients? -Correct
Answers ✔-simplifying drug regimens
providing clear and concise verbal and written instructions
using an appropriate dosage form
clearly labeling and dispensing easy-to-open containers
developing daily reminders
monitoring frequently
affordability of drugs

Do you need informed consent for genetic testing? -Correct Answers ✔-yes
What is the purpose of the Genetic Information Non-Discriminatory Act? -Correct
Answers ✔-Protects patients from discrimination by employers and insurance
providers based on genetic information
Difference between practice authority and prescriptive authority? -Correct
Answers ✔-Practice authority refers to the nurse practitioner's ability to practice
without physician oversight, whereas prescriptive authority refers to the nurse
practitioner's authority to prescribe medications independently and without
limitations.
Who regulates prescriptive authority? -Correct Answers ✔-the jurisdiction of a
health professional board. This may be the State Board of Nursing, the State Board
of Medicine, or the State Board of Pharmacy, as determined by each state.
