What is the normal range of serum calcium in adults?
3.10 to 4.10 mg/dL
5.55 to 6.55 mg/dL
8.50 to 10.50 mg/dL
13.41 to 14.51 mg/dL
The Correct Answer is C
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 D
Explanation
Choice A reason: This is incorrect because over-hydration is unlikely in a dehydrated patient. Over-hydration is a condition where the body has too much water, which can cause hyponatremia, edema, and cerebral swelling.
Choice B reason: This is incorrect because diarrhea is a cause, not a consequence, of dehydration. Diarrhea is the frequent and watery passage of stool, which can lead to fluid and electrolyte loss.
Choice C reason: This is incorrect because pulmonary congestion is also unlikely in a dehydrated patient. Pulmonary congestion is a condition where the lungs are filled with fluid, which can cause dyspnea, cough, and crackles.
Choice D reason: This is correct because fall is a potential complication of dehydration. Dehydration can cause confusion, dizziness, weakness, and hypotension, which can increase the risk of falling and injuring oneself.
Correct Answer is A
Explanation
Choice A reason: This is correct because metabolic alkalosis is characterized by a high pH and a high HCO3-. The client's pH and HCO3- are both high, indicating a metabolic disorder. The condition is uncompensated because the PaCO2 is normal, meaning the respiratory system is not compensating for the metabolic alkalosis.
Choice B reason: This is incorrect because metabolic acidosis is characterized by a low pH and a low HCO3-. The client's pH and HCO3- are both high, indicating alkalosis, not acidosis.
Choice C reason: This is incorrect because respiratory alkalosis is characterized by a high pH and a low PaCO2. The client's pH is high, but PaCO2 is normal, indicating a metabolic problem, not a respiratory one.
Choice D reason: This is incorrect because respiratory acidosis is characterized by a low pH and a high PaCO2. The client's pH is high, and PaCO2 is normal, indicating a metabolic problem, not a respiratory one.
