Question

Give normal saline 250 mL to 500 mL fluid bolus.

Answer 1

Administering a normal saline fluid bolus of 250 to 500 mL is a common intervention to address hypovolemia or low blood pressure. The decision is based on clinical assessment and provider orders.

Step-by-step explanation:

Administering a normal saline fluid bolus of 250 to 500 mL is a common medical intervention to address hypovolemia, dehydration, or low blood pressure. Normal saline, a sterile isotonic solution containing 0.9% sodium chloride, helps restore intravascular volume and electrolyte balance.

The decision to give a fluid bolus is based on the patient's clinical condition, vital signs, and the healthcare provider's assessment. This intervention is often utilized in emergency situations, such as severe dehydration, shock, or acute hypotension.

The rate of infusion and total volume administered depend on the severity of the patient's condition and the healthcare provider's orders. Close monitoring of vital signs during and after the fluid bolus is essential to ensure a proper response and to prevent potential complications.

Answer 2

The question involves calculating the mass of NaCl needed to prepare a 250 mL normal saline IV solution and its medical application for rehydration or blood loss compensation. Normal saline is a 0.16 M NaCl isotonic solution administered intravenously to match the osmotic pressure of bodily fluids.

Step-by-step explanation:

The question pertains to the calculation of the mass of sodium chloride (NaCl) required to prepare a normal saline solution, and the administration of fluid boluses to correct dehydration or replace blood loss in medical settings. Normal saline is a 0.16 M NaCl solution commonly used for intravenous injections. To calculate the mass of NaCl needed for 250 mL of this solution, one would use the formula: mass (g) = volume (L) × molarity (M) × molecular weight (g/mol). With the molecular weight of NaCl being approximately 58.44 g/mol, you can find the appropriate mass for the 250 mL solution.

Normal saline and lactated Ringer's solution are both isotonic solutions, meaning they have the same osmotic pressure as body fluids, which is crucial to prevent cellular damage during intravenous administration. A fluid bolus of 250 mL to 500 mL normal saline may be administered to quickly increase blood volume, correct electrolyte imbalances, or address dehydration.
