SECTION 1: PEDIATRIC AND GERIATRIC PHARMACOLOGY
CONSIDERATIONS (Questions 1-20)
Q1: Why do many medications lack pediatric dosing information in their drug
labeling?
A) Drug companies are not required to test medications in children
B) There is a lack of evidence-based literature on the safe and effective use of
medications in children
C) Children metabolize drugs the same way as adults
D) Pediatric studies are too expensive to conduct
Correct Answer: B
Rationale: There is a lack of evidence-based literature on the safe and effective use of
medications in children. This makes it challenging to determine appropriate pediatric
doses for many medications .
Q2: Why are neonates at greater risk for toxicity with highly protein-bound drugs?
A) Neonates have more plasma proteins than adults
B) Protein binding is decreased in neonates, increasing the amount of free drug
available
C) Neonates have faster drug metabolism
D) Neonates have increased renal clearance
Correct Answer: B
,Rationale: Protein binding is decreased in neonates, increasing the amount of free drug
available. This can lead to greater pharmacological effects and potential toxicity .
Q3: At what age are adult levels of renal function achieved?
A) 6 months
B) 12 months
C) 18 months
D) 24 months
Correct Answer: B
Rationale: Adult levels of renal function are achieved by 12 months of age. This is an
important consideration for dosing medications that are renally eliminated in pediatric
patients .
Q4: What is the most accurate device for measuring a 2.5 mL dose for a child?
A) Household teaspoon
B) Measuring cup
C) Oral syringe
D) Dropper
Correct Answer: C
Rationale: An oral syringe is the most accurate device for measuring a 2.5 mL dose for a
child. Household spoons and cups are not accurate for medication measurement .
Q5: How can medication errors be prevented when prescribing medications for
children?
A) Use abbreviations to save time
B) Write out the term "daily" rather than using abbreviations
C) Estimate doses based on age
D) Use adult doses for older children
,Correct Answer: B
Rationale: Writing out the term "daily" rather than using abbreviations helps prevent
medication errors. This is especially important in pediatric prescribing where dosing is
weight-based and errors can have serious consequences .
Q6: In pediatric patients, gastric acidity does not reach adult values until what
age?
A) 6 months
B) 1 year
C) 2 years
D) 3 years
Correct Answer: C
Rationale: In pediatric patients, gastric acidity does not reach adult values for 2 years.
This can affect the absorption of medications that require an acidic environment .
Q7: Nalidixic acid may cause what adverse effect in children?
A) Hepatotoxicity
B) Cartilage erosion
C) Nephrotoxicity
D) Ototoxicity
Correct Answer: B
Rationale: Nalidixic acid may cause cartilage erosion in children. This is why it is
generally avoided in pediatric patients .
Q8: Altered absorption of drugs in the elderly may result in what type of drug
response?
, A) Enhanced
B) Delayed
C) Accelerated
D) Unchanged
Correct Answer: B
Rationale: Altered absorption of drugs in the elderly may result in a delayed drug
response. Changes in gastric emptying, motility, and blood flow contribute to this effect
.
Q9: You have an elderly patient taking warfarin. You add another protein-binding
drug. Which statement is correct?
A) You will need to increase the dose of warfarin
B) You will need to decrease the dose of warfarin
C) No change in warfarin dose is needed
D) You should discontinue warfarin
Correct Answer: B
Rationale: When another protein-binding drug is added to a patient taking warfarin,
warfarin may be displaced from protein binding sites, increasing free warfarin levels and
the risk of bleeding. The warfarin dose may need to be decreased .
Q10: In the elderly, what is the proper index of renal function?
A) Serum creatinine
B) Blood urea nitrogen
C) Glomerular filtration rate (GFR)
D) Urine output
Correct Answer: C
