Which of the following does not describe intravenous injection.
Correct Answer: D
Rationale: The statement "Convenient, safe, economical" does not accurately describe intravenous injection. Intravenous injection is generally considered to be less convenient compared to other routes of administration due to the need for proper training, sterile technique, and close monitoring during drug administration. While it can be effective in delivering drugs quickly and directly into the bloodstream, it is not always the safest or most economical option. Intravenous administration carries risks such as infection, phlebitis, and possible adverse reactions that need to be carefully monitored. Additionally, the cost of intravenous drug administration tends to be higher due to the need for specialized equipment and trained personnel.
