Pharmacy and PharmacologyDifficulty 3/5

A 44 lb dog is prescribed 2 mg/kg of a drug supplied at 50 mg/mL. What volume should be drawn?

  1. A0.4 mL, using half the calculated dose for safety
  2. B2.0 mL, rounding the dose up to the nearest whole millilitre
  3. C1.76 mL, using the dog's weight in pounds for the calculation
  4. D0.8 mL, after converting the weight to 20 kilograms
Show answer and rationale

Correct: D. 44 lb ÷ 2.2 = 20 kg. 20 kg × 2 mg/kg = 40 mg. 40 mg ÷ 50 mg/mL = 0.8 mL. Skipping the pound-to-kilogram conversion inflates the answer 2.2-fold.

  • C — That result comes from using pounds directly as kilograms.
  • A — Halving a prescribed dose is not the technician's decision.
  • B — Rounding to a whole millilitre overdoses the patient by 150%.
Pharmacy and PharmacologyDifficulty 2/5

What is required when a portion of a controlled drug is not administered and must be discarded?

  1. ARecord the waste in the controlled-drug log according to practice protocol
  2. BReturn the remaining drug to the original vial for later use that day
  3. CDiscard it in general waste and note the full dose as administered
  4. DRetain the syringe in the controlled-drug safe until the end of the shift
Show answer and rationale

Correct: A. Controlled-drug waste must be documented in the log, with a witness where the protocol or jurisdiction requires it. Returning drug to a vial, mis-recording administration or holding an unlabelled syringe all breach handling requirements.

  • B — Returning drawn drug to a vial risks contamination and is not permitted.
  • C — Recording an unadministered dose as given falsifies the record.
  • D — Retaining an unlabelled syringe does not satisfy documentation requirements.
