Correct Answer:
Rationale:
Correct Answer: F: 1 mL
Rationale: The correct answer is 1 mL because to administer 0.25 mg of digoxin (Lanoxin), which is half of the 0.5 mg available in 2 mL, the nurse would need to administer 1 mL. This calculation is based on the proportion method where you set up a proportion (0.5 mg/2 mL = 0.25 mg/x mL) and solve for x. Cross-multiplying gives 0.5x = 0.5, which simplifies to x = 1 mL.
Therefore, the nurse will administer 1 mL of digoxin to achieve the prescribed dose of 0.25 mg.
Summary of other choices:
- The other choices are incorrect as they do not follow the correct calculation method or reasoning required to determine the correct volume of medication to administer.
