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. 25% albumin B. Dextrose 10% in water C. Dextrose 5% in water D. Dextran 40

Correct Answer is C

Explanation

C. Dextrose 5% in water is a hypotonic solution that contains 5 grams of dextrose in each 100 mL of water. It provides free water without adding significant sodium, which helps to dilute the elevated sodium levels in hypernatremia. This solution is effective in correcting hypernatremia by promoting water movement from the intravascular space into the cells and extracellular space.

A. Albumin solutions are primarily used for volume expansion and to increase oncotic pressure in conditions like hypoalbuminemia or shock. They do not provide free water and are not typically used for treating hypernatremia.

B. Dextrose 10% in water is a hypertonic solution used primarily for providing calories and treating hypoglycemia. It does not correct hypernatremia because it does not significantly affect sodium levels or provide sufficient free water to dilute sodium.

D. Dextran 40 is a colloid solution that is used for volume expansion in hypovolemia or shock. It does not provide free water and is not indicated for correcting hypernatremia.
