The Number That Changes the Dose
In a pediatric urgent care, you interpret for a Spanish-speaking mother and an English-speaking physician. The physician says: 'Tell mom to give 5 milliliters of the liquid every 6 hours, no more than 4 doses in 24 hours.' The mother responds in Spanish: '¿Cinco mililitros? Antes le daban una cucharadita.' You know that a household teaspoon is roughly 5 mL but that dosing by spoon is a common source of error. The physician has already turned to the computer. The pharmacy is on-site and the bottle label will print in English. The mother has limited literacy in Spanish and reads numbers but not English words.
1. How do you render the physician's instruction and the mother's question, and what do you do about the teaspoon comment?

I interpret everything faithfully and completely, and I surface the clinically relevant ambiguity rather than smoothing it over.
- Render the instruction exactly: '5 mililitros cada 6 horas, no más de 4 dosis en 24 horas.' I do not substitute 'una cucharadita' even though it's roughly equivalent, because the prescriber said milliliters.
- Interpret the mother's question verbatim: 'She asks: five milliliters? Before, they gave a teaspoon.'
- Flag the discrepancy to the provider as a communication clarification, not as my own medical advice: 'The mother is connecting 5 mL with a teaspoon. Do you want to clarify whether she should use the dosing syringe rather than a kitchen spoon?' This is appropriate because it concerns the accuracy of the message, not a clinical recommendation.
- Do not independently 'correct' or reassure the mother that a spoon is fine. That is the provider's call.
- Anticipate the label barrier: I can offer to have the provider or pharmacy give verbal instructions in Spanish and confirm the mother understands how to measure 5 mL with the dosing device.
Key judgment: exact numbers, no unit substitution, and escalating a foreseeable dosing ambiguity to the provider instead of resolving it myself.
2. The physician says, 'Just tell her a teaspoon is fine, it's basically the same.' How do you handle this?
Read the worked answer
I interpret what the provider says, but I also make sure the provider understands the risk they may be creating, because my job includes message accuracy.
- Interpret the provider's statement as given: 'Dice que una cucharadita está bien, que es casi lo mismo.'
- Raise the concern with the provider, not by overriding them: 'I want to make sure the message is clear - kitchen teaspoons vary, and the label will say 5 mL. Do you want to specify the dosing syringe so the measurement matches the prescription?' This frames it as a message-clarity issue.
- If the provider insists, I interpret faithfully and do not add my own warning. I may note afterward to the provider that the mother seemed unsure.
- Document nothing clinically myself; if the clinic has an interpreter note or communication log, I record that a clarification about measurement units was requested.
Key judgment: I don't refuse or editorialize to the patient, but I do give the provider the information they need to make an informed decision about how to phrase the instruction.
