Chapter 5 : Medication Errors: Preventing and Responding Questions
Question 1 of 5
When reviewing pediatric medication administration, the nurse recognizes that which type of medication error is most common with children?
Correct Answer: D
Rationale: Dosing errors are the most common medication errors in pediatrics due to weight-based calculations and variations in pediatric physiology. The other options are possible but less common.
Question 2 of 5
Levothyroxine is available in 0.1-mg tablet form. Convert this dose to microgram strength, (do not round)
Correct Answer: 100 mcg
Rationale: One mg equals 1000 mcg.
To convert 0.1 mg to mcg, multiply by 1000: 0.1 * 1000 = 100 mcg, or move the decimal point three spaces to the right.
Question 3 of 5
Digoxin is available in 0.25-mg tablet form. Convert this dose to microgram strength, (do not round)
Correct Answer: 250 mcg
Rationale: One mg equals 1000 mcg.
To convert 0.25 mg to mcg, multiply by 1000: 0.25 * 1000 = 250 mcg, or move the decimal point three spaces to the right.
Question 4 of 5
The nurse is reviewing medication errors. Which situation is an example of a medication error?
Correct Answer: B
Rationale: A medication error is defined as a preventable adverse drug event that involves inappropriate medication use by a patient or health care provider. A double dose due to not cutting a pill is a preventable error. Patient refusal, hives (a possible allergic reaction), and persistent pain are not preventable errors.
Question 5 of 5
The nurse is reviewing a list of verbal medication orders. Which is the proper notation of the dose of the drug ordered?
Correct Answer: C
Rationale: Levothyroxine 0.75 mg illustrates the correct notation with a leading zero before the decimal point. Omitting the leading zero (as in A and
B) may cause the order to be misread, resulting in a large drug overdose. Trailing zeros (as in
D) are also incorrect.
