Q1 QUESTION 1 OF 72
Principles of prescribing for older adults include:
1. Avoiding prescribing any newer high-cost medications
2. Starting at a low dose and increasing the dose slowly
3. Keeping the total dose at a lower therapeutic range
4. All of the above
RESPONSE
2. Starting at a low dose and increasing the dose slowly
RATIONALE
Older adults often exhibit altered pharmacokinetics and pharmacodynamics, leading to increased
sensitivity to medications. A "start low, go slow" approach minimizes the risk of adverse drug
events by allowing gradual titration to therapeutic effect while monitoring for toxicity. This strategy
accounts for potential declines in hepatic and renal function common in this population.
Q2 QUESTION 2 OF 72
Sadie is a 90-year-old patient who requires a new prescription. What changes in drug
distribution with aging would influence prescribing for Sadie?
1. Increased volume of distribution
2. Decreased lipid solubility
3. Decreased plasma proteins
4. Increased muscle-to-fat ratio
RESPONSE
3. Decreased plasma proteins
RATIONALE
Aging is associated with a reduction in albumin and other plasma proteins, which are primary
binding sites for many drugs. This leads to a higher fraction of unbound, pharmacologically active
drug, potentially increasing its intensity and duration of action. altered protein binding
significantly impacts drug distribution and requires careful dosage adjustment in geriatric
patients.

, Q3 QUESTION 3 OF 72
Glen is an 82-year-old patient who needs to be prescribed a new drug. What changes in
elimination should be taken into consideration when prescribing for Glen?
1. Increased glomerular filtration rate (GFR) will require higher doses of some renally
excreted drugs.
2. Decreased tubular secretion of medication will require dosage adjustments.
3. Thin skin will cause increased elimination via sweat.
4. Decreased lung capacity will lead to measurable decreases in lung excretion of drugs.
RESPONSE
2. Decreased tubular secretion of medication will require dosage adjustments.
RATIONALE
Aging adults often experience reduced renal function, specifically a decline in tubular secretion.
This impaired ability to actively transport drugs out of the body necessitates dosage adjustments
to prevent drug accumulation and potential toxicity. a decrease in medication clearance via this
pathway requires careful consideration in prescription.
Q4 QUESTION 4 OF 72
A medication review of an elderly person's medications involves:
1. Asking the patient to bring a list of current prescription medications to the visit
2. Having the patient bring all of their prescription, over-the-counter, and herbal
medications to the visit
3. Asking what other providers are writing prescriptions for them
4. All of the above
RESPONSE
4. All of the above
RATIONALE
Comprehensive medication reconciliation requires gathering all substances a patient is taking to
identify potential drug-drug interactions, duplicate therapies, or adverse effects. This includes
prescription drugs, over-the-counter products, and herbal supplements, as well as understanding
other healthcare providers involved in their care. This holistic approach ensures patient safety and
optimizes pharmacotherapy.

, Q5 QUESTION 5 OF 72
Steps to avoid polypharmacy include:
1. Prescribing two or fewer drugs from each drug class
2. Reviewing a complete drug history every 12 to 18 months
3. Encouraging the elderly patient to coordinate their care with all of their providers
4. Evaluating for duplications in drug therapy and discontinuing any duplications
RESPONSE
4. Evaluating for duplications in drug therapy and discontinuing any duplications
RATIONALE
Polypharmacy is defined as the concurrent use of multiple medications. Identifying and eliminating
redundant drug therapies directly addresses this issue, preventing unnecessary drug burden and
potential adverse events. This systematic evaluation is a cornerstone of safe medication
management, particularly in complex patient populations.
Q6 QUESTION 6 OF 72
Robert is a 72-year-old patient who has hypertension and angina. He is at risk for common
medication practices seen in the elderly including:
1. Use of another person's medications
2. Hoarding medications
3. Changing his medication regimen without telling his provider
4. All of the above
RESPONSE
4. All of the above
RATIONALE
Elderly patients are vulnerable to medication errors due to cognitive changes, complex regimens,
and social factors. Practices such as using others' prescriptions, stockpiling unused drugs, or
altering therapy without consultation can lead to adverse drug events. These behaviors collectively
increase the risk of suboptimal treatment outcomes.
