Magnesium is located primarily in the bones an inside cells. It is responsible for neuromuscular function. Normal magnesium (Mg+) level is

0.5-1.5mEq/L

1.3-2.1 mEq/L

2.5-3.5 mEq/L

1.0-3.0 mEq/L

Answer and Explanation

The Correct Answer is B

B. This range represents the normal serum magnesium level. It is important for maintaining neuromuscular function and other vital processes in the body.

A. This range is too low for normal serum magnesium levels. Magnesium levels below this range can indicate hypomagnesemia, which can lead to symptoms such as muscle cramps, tremors, and cardiac arrhythmias.

C. This range is too high for normal serum magnesium levels. Elevated magnesium levels (hypermagnesemia) can occur in conditions such as renal failure or excessive magnesium intake, leading to symptoms like weakness, decreased reflexes, and in severe cases, cardiac arrest.

D. While this range is broader and includes the correct normal range (1.3-2.1 mEq/L), it also includes values that are below and above normal. Values below 1.3 mEq/L can indicate hypomagnesemia, while values above 2.1 mEq/L can indicate hypermagnesemia.

Correct Answer is ["A","B","D"]

Explanation

A. Streak formation along the vein is a characteristic sign of phlebitis. It indicates inflammation and possibly thrombophlebitis (inflammation with clot formation) within the vein.

B. Erythema (redness) at the insertion site is a common early sign of phlebitis. It indicates localized inflammation of the vein.

C. Blistering around the insertion site is not typically associated with phlebitis. It may suggest a severe reaction or infection, but it is not a common manifestation of phlebitis itself.

D. Warmth at the insertion site is a common sign of inflammation, including phlebitis. It indicates increased blood flow and localized inflammatory response.

E. A damp dressing over the insertion site can contribute to the risk of infection but is not a direct manifestation of phlebitis. However, it can be a contributing factor to the development of phlebitis if moisture leads to skin breakdown or infection.

A. Hyperactive bowel sounds B. Cerebral edema C. Hypertension D. Muscle weakness

Correct Answer is D

Explanation

D. Muscle weakness is a hallmark sign of hypokalemia. Potassium is crucial for proper muscle contraction, and low levels can impair muscle function. This weakness can affect skeletal muscles (resulting in fatigue, cramps, or generalized weakness) as well as smooth muscles (contributing to constipation or other gastrointestinal symptoms).

A. Hypokalemia is not typically associated with hyperactive bowel sounds.

B. Cerebral edema is not typically associated with hypokalemia. Instead, cerebral edema can occur with conditions such as hyponatremia (low sodium levels) or other metabolic disturbances.

C. Hypokalemia is more commonly associated with hypotension (low blood pressure) rather than hypertension. Low potassium levels can affect vascular smooth muscle tone, potentially leading to vasodilation and hypotension.
