Choose an answer, then open the working. Each explanation says why the right answer is right and why the others are not.
An owner asks whether she can crush an enteric-coated tablet to hide it in food for her dog. What is the correct advice?
D. No; crushing defeats the protective enteric coating
An enteric coating stops the tablet dissolving in the stomach, either to protect the drug from acid or to protect the stomach from the drug. Crushing or splitting defeats it. Ask for a different formulation instead.
A multi-dose injectable vial was first broached 35 days ago. Its SPC gives an in-use shelf life of 28 days. Half the liquid remains and the printed expiry date is next year. What should be done?
D. Discard it; the in-use shelf life has ended
Once a vial is broached, the in-use shelf life in the SPC applies, because of the risk of contamination and degradation. The printed expiry applies only to unopened product. Mark the opening date on every vial.
How many milligrams of drug are there in 1 mL of a 2% w/v solution?
D. 20 mg
2% w/v = 2 g per 100 mL = 2000 mg per 100 mL = 20 mg/mL. Rule of thumb: % w/v × 10 = mg/mL. 2 mg and 200 mg are tenfold slips in either direction; 0.2 mg divides by 10 instead of multiplying.
Adrenaline (epinephrine) is supplied as a 1:1000 solution. What is its concentration?
B. 1 mg/mL
Ratio strength 1:1000 for a solid in a liquid means 1 g in 1000 mL, which is 1 mg/mL. 0.1 mg/mL is the 1:10,000 strength; confusing the two is a classic tenfold error.
5 g of a drug is dissolved and made up to 250 mL. What is the strength as % w/v?
B. 2%
% w/v = g per 100 mL. 5 g in 250 mL = 2 g in 100 mL = 2%. 20% and 0.2% are tenfold slips; 5% ignores the volume.
A vet gives a calf double the labelled dose of an antibiotic. Why is the label withdrawal period no longer reliable?
C. More drug must be cleared, so residues could exceed the MRL at label time
Withdrawal periods come from depletion studies at the labelled dose, route and duration. More drug, a longer course or a different route can leave residues above the MRL after the label time.
A farmer reports that a wormer, given correctly, no longer reduces faecal egg counts in his sheep. Is this a reportable adverse event?
C. Yes; lack of expected efficacy is reportable
Veterinary pharmacovigilance includes lack of expected efficacy, which may signal resistance. Reports help regulators and companies spot emerging anthelmintic or antimicrobial resistance.
