A patient's anxiety medication is an extended release tablet. The nurse should avoid:

A. 3.: One ounce is not equivalent to 3 tablespoons. This value overestimates the conversion and could lead to medication dosing errors, especially in liquid medication administration for pediatric or elderly clients.

B. 1.: One tablespoon equals 0.5 ounces, not a full ounce. Using this conversion would result in underdosing and reduce the intended therapeutic effect of a liquid medication.

C. 4.: Four tablespoons equal 2 ounces, so this conversion doubles the actual amount. Administering this volume could cause an overdose if the drug is potent or concentrated.

D. 2.: One ounce equals 2 tablespoons, which is the correct conversion. This standard measurement is important in both pharmacology and nutrition to ensure safe and accurate liquid medication dosing.

A. At the nurses' station while reviewing the provider's prescription: This is part of the preparation process but not the final safety check before administration.

B. At the time of documentation: Documentation occurs after administration, not before, and cannot prevent an error.

C. At the client's bedside right before administering the medication: The final check occurs at the bedside to verify the right patient, drug, dose, route, and time—ensuring safe medication delivery.

D. In the medication storage room: This is an early preparation step and does not confirm client identity or final accuracy at the point of administration.
