MTM Medication Safety & Error Prevention 4

Question 1

Which action BEST exemplifies applying a 'forcing function' to prevent a medication safety error?

Accepted Answer

Removing concentrated potassium from floor stock entirely

Answer

A forcing function physically prevents the error from occurring; removing concentrated potassium chloride from floor stock makes it impossible for nurses to administer it undiluted.

Question 2

A patient on lithium develops confusion and tremors after being prescribed ibuprofen for knee pain. The MTM pharmacist should recognize this as an example of:

Accepted Answer

Lithium toxicity from NSAID-induced renal clearance reduction

Answer

NSAIDs reduce renal prostaglandin synthesis, decreasing lithium clearance and raising serum lithium to toxic levels.

Question 3

Which metric is MOST appropriate for measuring the rate of adverse drug events in an MTM population?

Accepted Answer

ADEs per 1,000 patient-days or per 100 admissions

Answer

ADE rates expressed per patient-days or admissions normalize for population size and exposure time, making them a valid safety outcome measure.

Question 4

The Beers Criteria is PRIMARILY intended to help MTM pharmacists identify medications that are:

Accepted Answer

Potentially inappropriate in adults aged 65 and older

Answer

The AGS Beers Criteria lists medications that are potentially inappropriate in older adults due to unfavorable risk-benefit profiles in this population.

Question 5

A prescriber writes 'QD' for once-daily dosing. Why is this abbreviation considered unsafe?

Accepted Answer

It can be mistaken for 'QID' (four times daily), causing a fourfold dosing error

Answer

ISMP identifies 'QD' as error-prone because it can be misread as 'QID,' leading to four-times-daily dosing instead of once daily.
