Question

Match each fluid with its Na concentration:

NaCl 0.9%
Plasmalyte
LR
a) NaCl 0.9%: 154 mEq/L, Plasmalyte: 140 mEq/L, LR: 130 mEq/L
b) NaCl 0.9%: 140 mEq/L, Plasmalyte: 154 mEq/L, LR: 130 mEq/L
c) NaCl 0.9%: 130 mEq/L, Plasmalyte: 140 mEq/L, LR: 154 mEq/L
d) NaCl 0.9%: 130 mEq/L, Plasmalyte: 154 mEq/L, LR: 140 mEq/L

Answer 1

The correct match for each fluid with its sodium concentration is: NaCl 0.9% at 154 mEq/L, Plasmalyte at 140 mEq/L, and Lactated Ringer's at 130 mEq/L, corresponding to option (a).

Step-by-step explanation:

The question asks to match each fluid with its appropriate sodium (Na) concentration among the given options. In context, NaCl 0.9% is a commonly used intravenous saline solution, which is known to contain 154 mEq/L of Na+. This information matches option (a). Moreover, Plasmalyte, a balanced electrolyte solution used in intravenous therapy, contains sodium at a concentration of 140 mEq/L again matching option (a). Lastly, Lactated Ringer's (LR) solution which is also used as an IV fluid has a known sodium concentration of 130 mEq/L agreeing with option (a) once more. Therefore, the correct match is:

• NaCl 0.9%: 154 mEq/L
• Plasmalyte: 140 mEq/L
• LR: 130 mEq/L

This corresponds to choice (a) and reflects the standard concentrations for these fluids.
