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. Kayexalate (sodium polystyrene): This is the correct choice. Kayexalate is used to treat hyperkalemia (high serum potassium levels) by facilitating the removal of excess potassium from the body through the gastrointestinal tract.
B. Potassium chloride: This is used to treat hypokalemia (low potassium levels), not hyperkalemia.
C. Sodium bicarbonate: This can be used to correct metabolic acidosis and may indirectly help with potassium levels, but it is not the primary treatment for hyperkalemia.
D. Aldactone (spironolactone): This is a potassium-sparing diuretic that can increase potassium levels, which would be contraindicated in the case of hyperkalemia.

A. Non-steroidal anti-inflammatory drugs B. Cyclooxygenase-2 inhibitors C. Opioid analgesics D. Non-opioid pain medications

Correct Answer is C

Explanation

A. Non-steroidal anti-inflammatory drugs: These typically cause gastrointestinal upset and potential bleeding but are less likely to cause respiratory depression, constipation, or hypotension.
B. Cyclooxygenase-2 inhibitors: These are a subset of NSAIDs with fewer gastrointestinal side effects but do not generally cause respiratory depression or hypotension.
C. Opioid analgesics: This is the correct choice. Opioid analgesics are known to cause respiratory depression, constipation, nausea, vomiting, and hypotension.
D. Non-opioid pain medications: These include medications like acetaminophen and NSAIDs, which are less likely to cause respiratory depression or hypotension.
