Question 1: An 82-year-old patient with high blood pressure is starting a new medication and the
provider wants to follow the safest prescribing approach for this elderly patient. What is the most
important principle to follow when prescribing for this older adult?
A) Use the maximum recommended starting dose for best results
B) Start with a low dose and increase slowly over time
C) Prescribe the same dose as a young adult patient
D) Double the dose to account for slower metabolism

Answer: B) Start with a low dose and increase slowly over time
Rationale: The "start low, go slow" approach is the standard of care for elderly patients because they are
more sensitive to medications and have reduced clearance. Starting with a low dose and titrating slowly
prevents adverse reactions and toxicity.
Question 2: A newborn baby has an infection and needs antibiotic treatment, but the provider knows
that drug handling is different in infants compared to older children. Which statement best explains how
drug distribution is different in a newborn infant?
A) Newborns have more body fat, which stores lipid-soluble drugs
B) Newborns have less total body water, so drugs are more concentrated
C) Newborns have more total body water and less body fat than adults
D) Newborns have more protein binding, so less free drug is available
Answer: C) Newborns have more total body water and less body fat than adults
Rationale: Infants have a higher percentage of total body water (about 75-80%) and lower body fat
compared to adults. This affects the distribution of water-soluble and lipid-soluble drugs, requiring
different dosing considerations.

Question 3: The Beers Criteria is a list of medications that are considered potentially inappropriate for
which group of patients because the risks often outweigh the benefits?
A) Pediatric patients under age 2 years
B) Pregnant women in their first trimester
C) Elderly patients aged 65 years and older
D) Patients with liver disease
Answer: C) Elderly patients aged 65 years and older
Rationale: The Beers Criteria identifies medications that are potentially inappropriate for older adults
due to high risk of adverse effects, limited efficacy, or safer alternatives. It is a key reference for
prescribing to geriatric patients.
Question 4: A 7-year-old child has a severe infection and the provider is considering prescribing a
fluoroquinolone antibiotic. Why is this medication generally avoided in children unless there are no
other options?
A) It causes severe stomach upset in children
B) It may cause permanent joint and tendon damage
C) It is not effective against pediatric infections
D) It causes severe allergic reactions in children
, Page 4 of 168
Answer: B) It may cause permanent joint and tendon damage
Rationale: Fluoroquinolones such as ciprofloxacin and levofloxacin have been associated with tendonitis
and tendon rupture in children. They should only be used when no safer alternative is available for
serious infections.
Question 5: A mother is taking warfarin and also wants to take a garlic supplement to help lower her
cholesterol. What is the most important interaction the provider should warn this patient about?
A) Garlic will increase the effect of warfarin and increase bleeding risk
B) Garlic will decrease the effect of warfarin and cause blood clots
C) Garlic will cause severe stomach pain with warfarin
D) Garlic has no interaction with warfarin at all
Answer: A) Garlic will increase the effect of warfarin and increase bleeding risk
Rationale: Garlic has antiplatelet effects and can increase bleeding risk when combined with
anticoagulants like warfarin. Patients should be advised to avoid concurrent use or be monitored closely
for signs of bleeding.
