Ans: B. 105 mEq of magnesium ion
The image shown is of Ringer Lactate(Hartmann’s Solution)
Intravenous Fluids
- Substances that may be infused intravenously include volume expanders, blood-based products, blood substitutes, medications and nutrition.
Volume Expander
- Volume expanders may either be isotonic, hypotonic, or hypertonic.
- There are two main types of volume expander: crystalloids and colloids.
- Colloids preserve a high colloid osmotic pressure in the blood, while, on the other hand, this parameter is decreased by crystalloids due to hemodilution.
- Colloids (blood, albumin, plasma, etc.)contain larger insoluble molecules, such as gelatin.
- Crystalloids are aqueous solutions of mineral salts or other water-soluble molecules.
- The most commonly used crystalloid fluid is normal saline, a solution of sodium chloride at 0.9% concentration, which is close to the concentration in the blood (isotonic).This solution has 154 mEq of Na per liter
- Lactated Ringer’s (also known as Ringer’s lactate) and the closely related Ringer’s acetate, are mildly hypotonic solutions often used in those who have significant burns.
Ringer Lactate
- Also known as sodium lactate solution and Hartmann’s solution.
- It is used for replacing fluids and electrolytes in those who have low blood volume or low blood pressure.
- It may also be used to treat metabolic acidosis in cases other than those caused by lactic acidosis .
- Ringer’s lactate solution has a lower rate of acidosis as compared with normal saline.
- Use is generally safe in pregnancy and breastfeeding.
- Ringer’s lactate solution is in the crystalloid family of medication.
One liter of Ringer’s lactate solution contains:
- 130–131 mEq of sodium ion
- 109–111 mEq of chloride ion
- 28–29 mEq of lactate
- 4–5 mEq of potassium ion
- 2–3 mEq of calcium ion
