Flashcard 1: Which IV fluid is isotonic and commonly used for hypovolemia: 0.9%0.9\%0.9% NS or 0.45%0.45\%0.45% NS?

Answer: 0.9%0.9\%0.9% normal saline. Its osmolality matches plasma, expanding intravascular volume without causing cellular fluid shifts.

Flashcard 2: Which IV fluid is hypotonic: 0.45%0.45\%0.45% NS or lactated Ringer’s?

Answer: 0.45%0.45\%0.45% normal saline. Its lower osmolality than plasma draws fluid into cells, useful for hypernatremia correction.

Flashcard 3: Which IV fluid is hypertonic: 3%3\%3% saline or 0.9%0.9\%0.9% saline?

Answer: 3%3\%3% saline. Its high osmolality pulls fluid from cells into vasculature, treating severe hyponatremia.

Flashcard 4: Which electrolyte imbalance causes neuromuscular irritability and tetany: hypocalcemia or hypercalcemia?

Answer: Hypocalcemia. Low calcium increases neuronal excitability, leading to muscle spasms and potential tetany.

Flashcard 5: Which imbalance is a seizure risk requiring precautions: hyponatremia or hypernatremia?

Answer: Hyponatremia. Low sodium causes cerebral edema, lowering seizure threshold and necessitating protective measures.
