Which of the following are acceptable volumes of water-soluble medication to be given subcutaneously?
A. 4 ml
B. 0.5 ml
C. 1 ml
D. 3 ml
E. 0.75 ml
F. 2 ml
Answer (2)
The acceptable volumes of water-soluble medications for subcutaneous administration are generally 0.5 ml, 1 ml, 0.75 ml, and 2 ml. Volumes like 4 ml and 3 ml are generally not acceptable as they exceed the recommended limits. Always consider patient-specific factors and institutional guidelines when administering medication.

In medicine, the maximum volume that should be administered via a subcutaneous injection is generally small. Subcutaneous injections involve delivering medication into the tissue layer between the skin and the muscle, and it's important to ensure the volume is not too large to cause discomfort or affect absorption.
For water-soluble medications, the generally accepted practice is to administer volumes up to 1 mL subcutaneously. However, in some cases, up to 2 mL might be acceptable, depending on the medication and the site of injection.
Here is a breakdown of the volumes mentioned in your question:
4 mL: This volume is generally too large for subcutaneous administration and is inappropriate.
0.5 mL: This volume is acceptable for subcutaneous injections.
1 mL: This volume is commonly used and acceptable for subcutaneous injections.
3 mL: This is typically too large for a subcutaneous injection.
0.75 mL: This volume is acceptable for subcutaneous injections.
2 mL: This volume could be used subcutaneously in some situations, but care must be taken.
Therefore, among the options provided, 0.5 mL , 1 mL , and 0.75 mL are always acceptable for subcutaneous injection, while 2 mL can be considered in specific contexts, but 3 mL and 4 mL are not recommended for subcutaneous injections.
