Can the use of isotonic IV fluids cause problems?
Correct Answer: A
Rationale: The use of isotonic IV fluids can cause problems because they can lead to fluid overload, especially in patients with impaired kidney function or heart failure. This can result in symptoms such as swelling, shortness of breath, and increased blood pressure. Additionally, isotonic IV fluids can also cause electrolyte imbalances, such as hyponatremia or hypernatremia, which can have detrimental effects on the body's functioning. Therefore, it is important to carefully monitor the administration of isotonic IV fluids and adjust the dosage according to the patient's specific needs.
