Which statement regarding serum magnesium (Mg ++) is true? A) Alcohol-related diseases frequently cause low Mg+ levels.
B) Vomiting is not generally seen as a major cause of Mg+ loss.
C) Mg++ levels present similarly to calcium (Ca++) levels in the blood.
D) Mg+ deficiencies often result in low serum potassium (K+) levels.
E) Mg+ deficiencies must be treated before potassium (K+) deficiencies.

Option B,C,D and E.

Vomiting is not generally seen as a major cause of Mg+ loss.

C) Mg++ levels present similarly to calcium (Ca++) levels in the blood.

D) Mg+ deficiencies often result in low serum potassium (K+) levels.

Explanation:

Serum magnesium is the test that indicate the level of magnesium in the body. A person can have high serum magnesium or low serum magnesium.. serum magnesium is regulated by the kidney via henle loop.

A damage to the kidney can increase the magnesium level in the blood and cause hypermagnesemia. Renal failure cause magnesium excess and the body will not be able to excrete it.

Magnesium deficiency is similar to potassium deficiency.

A person with low magnesium may also have low calcium and low potassium because magnesium help to transport calcium and magnesium ions in and out of the body cells.

Administration magnesium is essential for correcting the hypokalemia. Magnesium deficiency inhibit and affect Na-K-ATPase, which in turn reduce cellular uptake of K+. A decrease in cellular uptake of K+, when it occurs along with increased urinary or gastrointestinal excretion, would lead to K+ wasting and hypokalemia.

magnesium deficiency exacerbates potassium wasting by increasing distal potassium secretion.

Vomiting is not a general cause of magnesium loss.

Therefore options B, C, D and E are correct

B) Vomiting is not generally seen as a major cause of Mg+ loss.

C) Mg++ levels present similarly to calcium (Ca++) levels in the blood.

D) Mg+ deficiencies often result in low serum potassium (K+) levels.

E) Mg+ deficiencies must be treated before potassium (K+) deficiencies.
