What is the normal range of serum chloride level in adults?
95-110 mg/dL
10-120 mEq/L
96-106 mEq/L
1.8-2.6 mEq/L
The Correct Answer is C
Choice A reason: This is incorrect because 95-110 mg/dL is the normal range of serum phosphorus level in adults, not chloride. Phosphorus is an electrolyte that is involved in energy metabolism, acid-base balance, and bone formation.
Choice B reason: This is incorrect because 10-120 mEq/L is not a realistic range for any electrolyte level in the blood. The units of mEq/L indicate the concentration of ions, not the mass of the substance. The normal range of serum chloride level in adults is expressed in mEq/L, not mg/dL.
Choice C reason: This is correct because 96-106 mEq/L is the normal range of serum chloride level in adults. Chloride is an electrolyte that is important for fluid balance, acid-base balance, and nerve transmission.
Choice D reason: This is incorrect because 1.8-2.6 mEq/L is the normal range of serum magnesium level in adults, not chloride. Magnesium is an electrolyte that is important for muscle and nerve function, as well as enzyme activity.

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.
Correct Answer is B
Explanation
Choice A reason: This is incorrect because filtration is a passive transport mechanism that does not require cellular energy. Filtration is the movement of fluid and solutes across a membrane due to hydrostatic pressure.
Choice B reason: This is correct because active transport is a transport mechanism that requires cellular energy in the form of ATP. Active transport is the movement of molecules across a membrane against their concentration gradient, using carrier proteins.
Choice C reason: This is incorrect because diffusion is a passive transport mechanism that does not require cellular energy. Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration, until equilibrium is reached.
Choice D reason: This is incorrect because osmosis is a passive transport mechanism that does not require cellular energy. Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.
