Which instruction would require a nurse to administer medication via "Im"?

Intramuscular administration, often abbreviated as IM, involves delivering medication directly into the muscle tissue. This route is commonly used for vaccines and certain medications because it allows for faster absorption into the bloodstream compared to some other methods, such as subcutaneous injections. In this context, the option referring to "Intramuscular" directly indicates the method of administration that aligns with the abbreviation "IM."

While the other options describe different routes or forms of medication delivery, they are not associated with the IM abbreviation. For example, "Eye" refers to procedures involving ocular medications, "Drop" could imply a liquid medication format, and "Inhalation" indicates that the drug is delivered via the respiratory system. Therefore, the best choice that clearly corresponds to the instruction for administering medication via "IM" is indeed intramuscular.
