Choice A reason: This action should be taken by the nurse to prevent medication errors, as it helps ensure that the medication is correct in terms of name, dose, route, time, and patient.

Choice B reason: This action should be taken by the nurse to prevent medication errors, as it helps ensure that the medication is measured and administered accurately and safely. Oral syringes or droppers are more precise and easier to use than cups or spoons for liquid medication.

Choice C reason: This action should be taken by the nurse to prevent medication errors, as it helps ensure that the medication dosage and calculation are correct and appropriate for the patient's weight and age. Another nurse can act as a double-check and catch any potential errors or discrepancies.

Choice D reason: This action should be taken by the nurse to prevent medication errors, as it helps ensure that the medication is given to the right patient. Comparing the infant's identification band with the MAR and asking the parent to confirm the infant's name are two ways of verifying the patient's identity.

Choice E reason: This action should not be taken by the nurse to prevent medication errors, as it may alter the effectiveness, absorption, or taste of the medication. Crushing or dissolving tablets or capsules and mixing them with formula or juice may also cause choking or aspiration in infants. The nurse should only administer medications that are in liquid form or prescribed to be crushed or dissolved.
