The nurse administering Mr. Brown's medication is aware that Tylenol # 3 is a controlled substance. The nurse must ensure that which of the following is completed?

A. Complete proper documentation of the medication error in the patient's chart: Documentation is an essential component of error management, but it is not the immediate priority. Patient safety takes precedence, and assessment must occur first to determine whether harm has occurred before completing documentation or incident reporting.

B. Return to the room to check and assess the patient: The first priority after recognizing a potential medication error is to assess the patient. This includes verifying identity, evaluating vital signs, assessing for adverse effects, and determining whether the correct medication was administered. Immediate assessment allows timely intervention if the wrong patient received medication.

C. Alert the charge nurse that a medication error has occurred: Notifying the charge nurse is appropriate after assessing the patient. However, reporting without first determining the patient’s current condition delays critical clinical evaluation and potential interventions.

D. Administer the antidote to the patient immediately: Administering an antidote without confirming that the wrong medication was given or that adverse effects are present could cause unnecessary harm. Treatment decisions must be based on assessment findings and verification of the specific error involved.

A. Specialized syringe graduated in units: Insulin syringes are specifically calibrated in units to match the insulin concentration (typically U-100). Using the correct syringe ensures accurate dosing, minimizes the risk of overdose or underdose, and promotes safe administration. This is essential because insulin dosing errors can lead to severe hypoglycemia or hyperglycemia.

B. Any syringe which has the correct needle length and gauge: Using a non-insulin syringe, even with the correct needle length, risks inaccurate dosing because standard syringes are not calibrated in insulin units. This could result in significant dosing errors and compromise patient safety.

C. TB Syringe: Tuberculin syringes are designed for small-volume intradermal or subcutaneous injections, but they are not graduated in insulin units. Using a TB syringe for insulin can lead to dosing inaccuracies, especially when doses exceed 1 mL or require precise unit measurement.

D. Standard 1 mL syringe and 28 gauge needle: While the needle size might be appropriate, standard 1 mL syringes are not calibrated in units for insulin. Administering insulin with such syringes increases the risk of dosing errors and is not recommended for routine insulin administration.
