The healthcare provider orders Ceftriaxone 20 mg IV every 6 hours. The instructions say to reconstitute 10 mg of Ceftriaxone with 6.5 ml of normal saline for a final concentration of 5 mg/ml. How many mL would the nurse administer? (Round to the nearest tenth)
The Correct Answer is ["13.3"]
Let's calculate the dosage step-by-step:
1. Determine the total daily dosage:
20 mg/dose x 4 doses/day = 80 mg/day
2. Calculate the volume needed for one dose:
20 mg / 1.5 mg/mL = 13.33 mL
3. Round to the nearest tenth:
13.33 L ≈ 13.3 mL

Correct Answer is D
Explanation
A) The nurse reports the error to the physician and the charge nurse but does not document the error due to possible legal action: Ethical reporting includes thorough documentation of the error, regardless of potential legal implications. Failing to document the error could compromise patient safety and the quality of care, and it does not fulfill the requirement for transparent and comprehensive reporting.
B) The nurse does not report or document the error, since the error did not result in any harm to the patient: Ethical reporting of medication errors involves documenting and reporting all errors, regardless of whether harm occurred. This helps in preventing future errors and maintaining a culture of safety and accountability.
C) The nurse does not report the error, because the error was caught and corrected prior to drug administration: Even if the error was corrected before administration, it is crucial to report and document the incident. This practice helps identify potential systemic issues and improve safety protocols.
D) The nurse informs the patient, documents the error as per hospital policy, and notifies the physician: This action demonstrates ethical reporting as it includes informing the patient about the error, thoroughly documenting it according to hospital policy, and notifying the physician. This comprehensive approach ensures transparency, patient safety, and adherence to institutional guidelines.
Correct Answer is C
Explanation
A) 2 mg: This dosage is incorrect because it represents two milligrams, which is ten times the intended amount of two-tenths of a milligram (0.2 mg). The intended dosage is much smaller, so this option does not accurately represent the prescribed amount.
B) 0.20 mg: Although this representation is correct, the trailing zero is not necessary and can lead to potential confusion or errors. Standard practice often omits the trailing zero to simplify and clarify dosage instructions.
C) 0.2 mg: This is the most appropriate and clear way to write two-tenths of a milligram. It includes a leading zero before the decimal point, which is important for clarity and reducing the risk of misinterpretation. This format adheres to best practices in medication transcription.
D) 2.0 mg: This option is incorrect because it represents two milligrams, not two-tenths of a milligram. The decimal point and trailing zero do not change the fact that the dosage is significantly larger than what is intended.
