The nurse administered a routine scheduled medication of Prozac (fluoxetine hydrochloride), an antidepressant, 20 mg PO to a patient. The nurse checked the medication label against the MAR when getting it out of the automatic dispensing system, again when placing the medication in a cup, and once more at the patient's bedside prior to administration. The label read 20 mg and contained a single capsule. The nurse asked the patient to state her name and administered the medication, offering the patient a drink of water. The nurse documented the administration of the medication. Which of the six rights of medication administration did the nurse violate?

A) 1.5: Administering 1.5 mL of Amoxil would provide 37.5 mg of amoxicillin (125 mg per 5 mL translates to 25 mg per mL), which is insufficient to meet the ordered dose of 0.05 g (50 mg). Accurate dosing is essential for effective treatment.

B) 0.5: Giving 0.5 mL would result in only 12.5 mg of amoxicillin, which is significantly below the prescribed dose of 0.05 g. It's crucial to ensure the dose administered aligns with the healthcare provider's orders to achieve the desired therapeutic effect.

C) 2: Administering 2 mL of Amoxil is correct. At a concentration of 125 mg per 5 mL, this dosage provides 50 mg of amoxicillin (2 mL x 25 mg/mL = 50 mg), which meets the prescribed order and ensures proper treatment.

D) 1: One mL would deliver 25 mg of amoxicillin, which is still inadequate compared to the required dose of 50 mg. Proper dosing ensures the medication's efficacy while minimizing the risk of resistance and treatment failure.

A) The nurse administered the medication correctly: While the nurse followed many of the correct procedures, this option overlooks the critical issue of patient identification. The nurse's adherence to the six rights is not complete without the appropriate verification of the patient’s identity.

B) The nurse did not have a second nurse verify the dose: While having a second nurse verify high-risk medications is a good practice, it is not a strict requirement for every medication. The focus should be on the established protocols for verification rather than a blanket requirement for all doses.

C) The nurse did not make the appropriate number of checks for the right drug: The nurse followed proper procedures by checking the medication label multiple times against the MAR and at the bedside. Therefore, this option does not accurately reflect any violation.

D) The nurse did not use two patient identifiers: Although the nurse asked the patient to state her name, this alone does not constitute using two identifiers. The best practice is to confirm at least two identifiers (e.g., name and date of birth) to ensure the correct patient receives the medication. This oversight is a violation of the right patient in the medication administration process.
