The nurse is caring for a client with a serum magnesium of 2.9 mEq/L. The nurse should anticipate a prescription from the primary healthcare provider for what treatment?

Fluid restriction

Furosemide (Lasix)

Calcium carbonate (Tums)

Magnesium oxide (MagOx)

Answer and Explanation

The Correct Answer is B

A. Fluid restriction: Fluid restriction is not indicated for high serum magnesium levels. It is generally used for conditions like heart failure or renal impairment, but not specifically for managing hypermagnesemia.
B. Furosemide (Lasix): This is the correct choice because furosemide is a diuretic that can help promote the excretion of excess magnesium through the urine. It is an appropriate treatment for hypermagnesemia, which is indicated by the elevated serum magnesium level.
C. Calcium carbonate (Tums): This option is incorrect as calcium carbonate is typically used to treat hypomagnesemia (low magnesium levels) or to bind excess phosphate, not to manage elevated magnesium levels.
D. Magnesium oxide (MagOx): This is not suitable because magnesium oxide would increase the magnesium level further, not decrease it. It is used to supplement magnesium in cases of deficiency, not to treat hypermagnesemia.

Correct Answer is B

Explanation

A. Flush the IV site with normal saline, then restart the IV potassium therapy: Flushing and restarting the infusion at the same site is not appropriate if there is redness and swelling, as these are signs of possible phlebitis or infiltration.
B. Discontinue the IV and restart in another site: This is the correct choice. Given the erythema and edema, which indicate possible complications like phlebitis or infiltration, the IV should be discontinued and restarted in a new site to prevent further complications.
C. Flush the IV site with heparin: This is not appropriate for erythema and edema and could exacerbate the problem. Heparin is used to maintain patency of IV lines, not to treat complications.
D. Stop the IV site and check for blood return: While checking for blood return is a good practice to assess for patency, the primary action should be to discontinue the IV and start a new one due to the complications at the site.

A. 10% dextrose in water B. 10% dextrose in 0.45% sodium chloride C. 0.9% sodium chloride D. 2.5% sodium chloride

Correct Answer is C

Explanation

A. 10% dextrose in water: This solution is used primarily for providing calories and is not suitable for volume replacement.
B. 10% dextrose in 0.45% sodium chloride: This solution combines dextrose and a hypotonic sodium chloride solution, which is not ideal for immediate volume replacement in severe bleeding cases.
C. 0.9% sodium chloride: This is the correct choice. Normal saline (0.9% sodium chloride) is an isotonic solution used for volume replacement, especially in cases of significant blood loss.
D. 2.5% sodium chloride: This is a hypotonic solution and would not be appropriate for volume replacement in severe bleeding as it does not adequately address the need for fluid resuscitation.
