How many tablets should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.) 0.5 tablet(s) Correct Rationale: Ratio and Proportion/brSTEP 1: What is the unit of measurement the nuse should calculate? tablet br/STEP 2: What is the dose the nurse should administer?
