C. Dyspnea: While dyspnea can occur, it is not as specific as a thready pulse for hypovolemia.
D. Decreased heart rate: Hypovolemia usually causes an increased heart rate as the body tries to compensate for low blood volume.

A. Decreased calcium level B. Decreased potassium level C. Elevated magnesium level D. Elevated sodium level

Correct Answer is B

Explanation

A. Decreased calcium level: NG tube drainage primarily affects sodium, potassium, and chloride levels rather than calcium.
B. Decreased potassium level: Large volumes of gastric drainage can result in significant potassium loss, leading to hypokalemia.
C. Elevated magnesium level: NG tube drainage does not typically cause elevated magnesium levels.
D. Elevated sodium level: NG tube drainage is more likely to cause decreased sodium levels due to fluid loss and electrolyte imbalance.
