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)

A) Palliative therapy: Palliative therapy is aimed at providing relief from symptoms and improving the quality of life in patients with serious or terminal illnesses. It does not pertain to the use of antibiotics before culture results are available.

B) Prophylactic therapy: Prophylactic therapy is used to prevent the occurrence of an illness or infection before it happens. For example, antibiotics given before surgery to prevent infections would be considered prophylactic therapy, but this is not the case here.

C) Maintenance therapy: Maintenance therapy is used to sustain a desired level of therapeutic effect after an initial treatment phase. It focuses on keeping a condition under control rather than addressing an acute or uncertain condition.

D) Empiric therapy: Empiric therapy refers to the use of antibiotics or other medications based on clinical judgment and initial symptoms before the results of diagnostic tests, such as wound cultures, are available. This approach is used to start treatment promptly and manage the infection while awaiting precise identification of the pathogen.

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.
