Available Dose = 400 mg

  • Convert Ordered Dose to mg

Ordered Dose = 1.2 × 1000

Correct Answer is C

Explanation

Calculation:

Ordered Dose = 0.8 g

Available Dose = 400 mg

Available Volume = 5 mL

  • Convert Ordered Dose to mg

Ordered Dose = 0.8 × 1000

= 800 mg

Volume to administer = (Ordered Dose / Available Dose) × Available Volume

= (800 / 400) × 5

= 2 × 5

= 10 mL

Correct Answer is B

Explanation

Rationale:
A. It shows the drug's physical description: The physical description, such as color, shape, or form, helps with identification but does not indicate why the drug should be used.

B. It specifies the conditions the drug is meant to treat: Indications provide critical information about the therapeutic purpose of the medication. Knowing the intended use ensures the drug is given for appropriate conditions, supporting safe and effective treatment.

C. It lists potential side effects: Side effects are important safety information but are separate from the indication, which focuses on the therapeutic goal rather than possible adverse reactions.

D. It provides the manufacturing process details: Information about how the drug is manufactured does not guide clinical use. Indications directly inform the nurse and patient about the drug’s intended purpose.
