Question

Identify the fluid shown below on the basis of composition:
Na+ 131mmol/L
Cl- 111 mmol/L
Lactate 29 mmol/L
K+ 5 mmol/L
Ca2+ 2 mmol/L
Total 279mOsm/L

• A. Haemaccel
• B. Ringer lactate
• C. Isolyte
• D. Isolyte M

Answer 1

The Correct Option is B

To identify the fluid based on its composition, we need to compare the given electrolyte levels and the total osmolarity with standard values for the fluids listed in the options.

Given composition:

• Na⁺: 131 mmol/L
• Cl^-: 111 mmol/L
• Lactate: 29 mmol/L
• K⁺: 5 mmol/L
• Ca²⁺: 2 mmol/L
• Total: 279 mOsm/L

Analyzing each option:

1. Haemaccel: Typical Haemaccel solutions contain Na⁺, Cl^-, K⁺, and Ca²⁺ but not lactate, and have different total osmolarities.

2. Ringer lactate: Composed of Na⁺, Cl^-, K⁺, Ca²⁺, and lactate. The typical osmolarity and ion composition closely match this fluid.

3. Isolyte: Typically caters to different ion balance and does not primarily include lactate.

4. Isolyte M: Used for different ionic compositions, again not primarily based on lactate.

Conclusion: The fluid closely resembles Ringer lactate based on the provided electrolytic values and osmolarity, which is commonly used for volume replacement and maintaining electrolyte balance.
