The patient who was admitted after vomiting for 3 days would show an abnormally low blood pressure because of a fluid shift from:
intracellular to the extracellular.
interstitial to intravascular.
interstitial to the intracellular.
intravascular to the interstitial.
The Correct Answer is D
Choice A reason: Intracellular to the extracellular fluid shift is not the cause of low blood pressure in this case. This fluid shift occurs when the cells lose water due to osmosis, such as in dehydration or hypernatremia.
Choice B reason: Interstitial to intravascular fluid shift is not the cause of low blood pressure in this case. This fluid shift occurs when the fluid moves from the tissue spaces to the blood vessels, such as in hypovolemia or hypotonic fluid administration.
Choice C reason: Interstitial to the intracellular fluid shift is not the cause of low blood pressure in this case. This fluid shift occurs when the fluid moves from the tissue spaces to the cells, such as in overhydration or hyponatremia.
Choice D reason: Intravascular to the interstitial fluid shift is the cause of low blood pressure in this case. This fluid shift occurs when the fluid moves from the blood vessels to the tissue spaces, such as in edema, inflammation, or increased capillary permeability. This reduces the blood volume and lowers the blood pressure.

Correct Answer is A
Explanation
An isotonic solution is a solution that has the same osmotic pressure as another solution, which means that the solute concentration on both sides of a semipermeable membrane is equal. This causes no net movement of water across the membrane, and the cells remain the same size and shape. An example of an isotonic solution is normal saline (0.9% sodium chloride), which is used to treat dehydration and fluid loss.
Correct Answer is C
Explanation
Choice A reason: This is a low value for serum calcium, which indicates hypocalcemia. Hypocalcemia can cause muscle spasms, tetany, seizures, and cardiac arrhythmias.
Choice B reason: This is also a low value for serum calcium, which indicates hypocalcemia. Hypocalcemia can cause muscle spasms, tetany, seizures, and cardiac arrhythmias.
Choice C reason: This is the normal range of serum calcium in adults. Calcium is essential for bone health, muscle contraction, nerve transmission, and blood clotting.
Choice D reason: This is a high value for serum calcium, which indicates hypercalcemia. Hypercalcemia can cause nausea, vomiting, constipation, confusion, lethargy, and kidney stones.
