Safety and Infection Control Flashcards

A client reports a known allergy to ragweed. Which essential oil family should an aromatherapist avoid due to potential cross-reactivity?

Answer: Compositae (Asteraceae) oils such as chamomile

Clients allergic to ragweed may cross-react with Compositae family plants, including chamomile and yarrow essential oils.

What is the safest method for an aromatherapist to verify that a diluted blend is appropriate before applying it to a sensitive client?

Answer: Perform a 24-hour patch test on the inner forearm

A 24-hour patch test on a small skin area detects delayed hypersensitivity reactions before full application.

Which personal protective measure should a practitioner take when working with highly sensitizing essential oils like cinnamon bark or clove?

Answer: Wear nitrile gloves during blending and application

Nitrile gloves protect the practitioner's skin from sensitizing compounds found in oils like cinnamon bark and clove.

A clinical aromatherapy setting should discard opened essential oils after what general timeframe to prevent oxidation-related skin sensitization?

Answer: 1–2 years for most oils stored properly

Most essential oils degrade and oxidize within 1–2 years of opening, increasing the risk of skin sensitization.

Which infection control practice is essential between each aromatherapy client session?

Answer: Cleaning and disinfecting all surfaces the client contacted

Cleaning and disinfecting all contact surfaces between clients prevents cross-contamination and pathogen transmission.

An aromatherapist notices a client has an open wound on their arm. What is the correct action regarding topical essential oil application?

Answer: Avoid applying any essential oils on or near the open wound

Essential oils should not be applied on or near open wounds as they can cause irritation, infection risk, or impair healing.

When labeling an essential oil blend for a client to use at home, which safety information is most critical to include?

Answer: Dilution percentage, intended use, and keep-away-from-eyes warning

Labels must include dilution percentage, intended use, and key safety warnings to ensure safe home use.
