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 A

Explanation

A. Hypocalcemia: Hypocalcemia can cause signs such as muscle twitching, spasms, or tetany, which could be observed in the upper extremity and might be noted during a blood pressure measurement.
B. Hypokalemia: While hypokalemia can cause muscle weakness and cramping, it is less directly associated with specific upper extremity signs compared to hypocalcemia.
C. Hypophosphatemia: This generally affects energy levels and muscle function but is less commonly associated with immediate and visible upper extremity signs.
D. Hyponatremia: This primarily affects fluid balance and mental status, and is less likely to present with specific upper extremity findings during a blood pressure check.

A. Level of consciousness B. Condition of drains C. Appearance of the surgical dressing D. Stability of vital signs

Correct Answer is D

Explanation

A. Level of consciousness: While important, it follows the assessment of vital signs to ensure the client's overall stability.
B. Condition of drains: This is relevant but not as immediate as assessing the stability of vital signs.
C. Appearance of the surgical dressing: This is important but secondary to ensuring the client’s vital signs are stable.
D. Stability of vital signs: This is the most critical next assessment after ensuring a patent airway, as vital signs reflect the client's immediate physiological status and stability.
