1. 1What does medication reconciliation compare to identify discrepancies?

   1. A. Comparing current medication use with transition-of-care orders
   2. B. Counting remaining medication supplies to estimate missed doses
   3. C. Reviewing reported symptoms to classify medication allergies
   4. D. Comparing prescription fill dates to calculate days of coverage

   Answer: A

   Explanation: AHRQ states, "It is a comparison of the patient's current medication regimen against the physician's admission, transfer, and/or discharge orders to identify discrepancies." Reconciliation compares the regimen with transition orders. Pill counts, allergy classification, and refill-based adherence assessment address related but different medication-history tasks.

2. 2A prescription is for ampicillin, but the dispensed bottle contains amoxicillin. Which medication-error type is present?

   1. A. Wrong time
   2. B. Wrong route
   3. C. Wrong duration
   4. D. Wrong drug

   Answer: D

   Explanation: NCC MERP lists "Wrong Drug" as an error type. The active medication differs from the prescribed medication; the discrepancy is not merely timing, route, or treatment length.

   Reference: NCC MERP Taxonomy of Medication Errors — Section 70.4, Wrong Drug, p. 13

3. 3In medication reconciliation, which difference is an unintended discrepancy?

   1. A. A change explained by the patient's current clinical condition
   2. B. A substitution explained by the hospital's formulary status
   3. C. A difference unexplained by clinical condition or formulary status
   4. D. A dose adjustment documented as the prescriber's intended change

   Answer: C

   Explanation: AHRQ describes unintended discrepancies as "those not explained by the patient's clinical condition or formulary status". A documented intentional change does not meet this description.

   Reference: Medications at Transitions and Clinical Handoffs (MATCH) Toolkit — Introduction — Introduction, medication reconciliation activities, second bullet

4. 4Which notation for a prescribed microgram dose does ISMP recommend to reduce confusion with milligrams?

   1. A. mcg
   2. B. mg
   3. C. µg
   4. D. ng

   Answer: A

   Explanation: For the microgram symbol µg, ISMP identifies the error "Mistaken as mg" and recommends "Use mcg". The abbreviation mcg retains microgram meaning without the error-prone symbol; mg and ng are different mass units.

   Reference: ISMP List of Error-Prone Abbreviations, Symbols, and Dose Designations — p. 2, µg (Microgram) row

5. 5Which mechanism distinguishes a drug allergy from a nonallergic adverse effect?

   1. A. A reaction caused by taking a dose later than scheduled
   2. B. An immune response directed against the medication
   3. C. A reaction caused by taking less than the intended dose
   4. D. A decline in benefit caused by stopping the medication

   Answer: B

   Explanation: MedlinePlus states, "A drug allergy involves an immune response in the body that produces an allergic reaction to a medicine." Dose timing, underdosing, and discontinuation do not define an allergy.

   Reference: Drug allergies — MedlinePlus Medical Encyclopedia — Causes, first paragraph

6. 6The prescription authorizes 30 capsules, but the bottle contains 20. The drug, strength, and directions match. Which dispensing discrepancy requires clarification?

   1. A. Incorrect route of administration
   2. B. Incorrect duration of the written order
   3. C. Incorrect quantity dispensed
   4. D. Incorrect concentration of each capsule

   Answer: C

   Explanation: PSNet states that dispensing includes releasing "the appropriate quantity of the medication in the correct form." The supplied count differs from the authorized quantity.

7. 7A patient reports nausea after taking a medicine and calls it an allergy. What does this report alone establish?

   1. A. Confirmation that the nausea was an immune-mediated allergy
   2. B. Evidence of immunologic cross-reactivity to related medicines
   3. C. Confirmation of an overdose rather than a medication side effect
   4. D. A reported adverse symptom that needs clarification before allergy classification

   Answer: D

   Explanation: MedlinePlus explains, "Many people confuse an unpleasant, but not serious, side effect of a medicine (such as nausea) with a drug allergy." Record the reported symptom and seek clarification rather than equating nausea alone with confirmed allergy.

   Reference: Drug allergies — MedlinePlus Medical Encyclopedia — Causes, paragraph on side effects

8. 8Medication ordered for oral use is mistakenly administered intravenously. Which error category describes this mismatch?

   1. A. Wrong dosage form
   2. B. Wrong route of administration
   3. C. Wrong administration time
   4. D. Wrong treatment duration

   Answer: B

   Explanation: NCC MERP lists "Wrong Route of Administration". The intended oral route and actual intravenous route differ; the question supplies no separate formulation, timing, or duration error.

   Reference: NCC MERP Taxonomy of Medication Errors — Section 70.7, Wrong Route of Administration, p. 13

9. 9What is an adverse drug event (ADE) in medication-safety terminology?

   1. A. An error intercepted before medication reaches a patient
   2. B. Harm a patient experiences from exposure to a medication
   3. C. An incorrect dose given without resulting patient harm
   4. D. A prescribing discrepancy regardless of any patient injury

   Answer: B

   Explanation: PSNet defines an ADE as "harm experienced by a patient as a result of exposure to a medication." Intercepted errors, errors without harm, and discrepancies alone do not establish medication-related injury.

   Reference: Medication Errors and Adverse Drug Events — PSNet — Background and Definitions, first paragraph

10. 10A patient was instructed to take one 10-mg tablet per dose but mistakenly takes two of those tablets each time. Which error best describes the amount taken?

    1. A. Wrong drug identity
    2. B. Wrong product strength
    3. C. Wrong administration route
    4. D. Improper dose resulting in overdosage

    Answer: D

    Explanation: NCC MERP lists "Improper Dose" and its subcategory "Resulting in Overdosage". The tablets have the prescribed strength; taking two doubles the prescribed dose.

    Reference: NCC MERP Taxonomy of Medication Errors — Section 70.2, Improper Dose, p. 13
