In what syringe should a 625 ml of a drug solution be measured?

The correct answer is D, a 5 ml slip tip syringe. The rationale is that a 625 ml drug solution cannot be accurately measured using an insulin syringe (A) due to its small volume capacity. Similarly, a 1 ml TB syringe (B) is too small for this volume. A 3 ml syringe (C) may not provide enough capacity to accurately measure 625 ml. Therefore, the most suitable option is a 5 ml slip tip syringe (D) as it has sufficient capacity to hold and accurately measure the 625 ml drug solution.
