A client with hypermagnesemia is prescribed calcium gluconate. Which action is appropriate for the nurse to take?
Administering calcium gluconate to counteract magnesium toxicity
Initiating IV fluid restriction
Administering potassium chloride to balance electrolytes
Increasing the dose of magnesium sulfate
The Correct Answer is A
Rationale:
A. Calcium gluconate is the antidote for magnesium toxicity; it helps reverse the cardiac and neuromuscular effects of hypermagnesemia.
B. IV fluid restriction is not appropriate; often IV fluids are given to promote magnesium excretion.
C. Potassium chloride is not indicated for hypermagnesemia treatment.
D. Increasing magnesium sulfate would worsen hypermagnesemia and is contraindicated.

Correct Answer is C
Explanation
Rationale:
A. While nosebleeds should be reported, this is not an administration instruction.
B. Cleaning the nostril before and after is not typically required and could irritate mucosa.
C. Alternating nostrils daily helps prevent irritation and promotes better absorption, which is the correct teaching.
D. Vitamin D supplements may increase calcium levels, which is contraindicated in hypercalcemia.
Correct Answer is A
Explanation
Rationale:
A. TUMS (calcium carbonate) is an alkaline antacid. Excessive use can lead to increased bicarbonate levels in the blood, causing metabolic alkalosis, especially when used to neutralize gastric acid frequently.
B. Metabolic acidosis would be more likely with diarrhea, renal failure, or overuse of acidic substances, not antacids.
C. Respiratory acidosis is caused by hypoventilation and CO₂ retention, such as in chronic lung disease, not by taking antacids.
D. Respiratory alkalosis is associated with hyperventilation, anxiety, or high altitude—not relevant to antacid use.
