Correct Answer is D
Explanation
A. 50-100G:This range of gauge sizes is not used for standard injection needles. As the gauge number increases, the needle diameter decreases; a 50G needle would be extremely fine, likely too small to effectively administer viscous IM medications.
B. 28-31G:This range of small gauges is typically used for intradermal or subcutaneous injections, particularly for insulin (30-31G) or tuberculin testing. They are generally too small for the deeper penetration and often thicker viscosity of IM medications.
C. 25-27G:The smaller part of this range (27G) is often used for intradermal or very small subcutaneousinjections. While 25G can sometimes be used for IM injections in thin individuals or with non-viscous medications, the range is generally too small to be considered the standard for IM.
D. 18-25G:This broad range includes the standard gauges for IM injections. 22G-25G is commonly used for less viscous medications, while 18G-21G may be used for highly viscous (thicker) medications or for rapid fluid administration.
Correct Answer is D
Explanation
Step 1: Convert ounces to milliliters
- 1 ounce = 30 mL.
- 2 ounces = 2 × 30 mL = 60 mL.
Step 2: Compare with available supply
- Each container = 30 mL.
- Ordered dose = 60 mL.
- Number of containers = 60 ÷ 30 = 2 containers.
