The nurse brings the patient's medications but the patient refuses to take them, stating, "I'll take them later. Right now my stomach feels a little upset. Could you please bring me some crackers?" What is the best action the nurse should take? (Select all that apply.)

A) 1.0: Administering 1.0 mL of Amikin would provide only 250 mg of amikacin, as the concentration is 1 g per 4 mL (or 250 mg per mL). This dosage is insufficient for the ordered dose of 500 mg.

B) 2.0: Administering 2.0 mL of Amikin is correct. With the available concentration of 1 g per 4 mL, 2.0 mL would deliver 500 mg of amikacin (2 mL x 250 mg/mL = 500 mg), fulfilling the healthcare provider's order for the medication.

C) 2.5: Giving 2.5 mL would result in a total of 625 mg of amikacin, which exceeds the prescribed dose of 500 mg. It's critical to adhere to the prescribed dosage to prevent potential toxicity and ensure patient safety.

D) 1.5: Administering 1.5 mL would provide 375 mg of amikacin, which is still less than the required 500 mg. Accurate dosing is essential in achieving the therapeutic effect and avoiding complications.

A) Administer 2.5 mL of amoxicillin per dose: This option is incorrect because administering 2.5 mL would only provide 62.5 mg of amoxicillin (since 125 mg is in 5 mL). The prescribed dose is 250 mg, so this volume is insufficient.

B) Administer 10 mL of amoxicillin per dose: This option is also incorrect. Administering 10 mL would provide 250 mg of amoxicillin (since 125 mg is in 5 mL, 10 mL equals 250 mg). However, this option may confuse the correct volume with a miscalculation if misunderstood in context, so it should not be selected without a proper calculation verification.

C) Administer the amoxicillin at 0800, 1200, and 1800: This option is correct. Administering the medication every 8 hours at these times ensures that the medication is given according to the prescribed schedule, maintaining appropriate therapeutic levels.

D) Compare the patient's name and date of birth on the armband with the MAR: This action is crucial for ensuring patient safety. Verifying patient identifiers against the MAR helps prevent medication errors and ensures that the right patient receives the correct medication.

E) Administer the medication by the parenteral route: This option is incorrect. The order specifies oral (PO) administration of amoxicillin, so administering it parenterally would not align with the prescribed route and could lead to incorrect dosing or complications.
