Answer to Question 1

ANS: B
A patient having a panic attack will hyperventilate, blowing off carbon dioxide, and develop respiratory alkalosis.
Respiratory acidosis most often results from hypoventilation.
Metabolic acidosis often results from diarrhea.
Metabolic alkalosis most often results from vomiting.
NOTE: Respiratory alkalosis can be compensated for by metabolic acidosis; respiratory acidosis by metabolic alkalosis; metabolic acidosis by respiratory alkalosis; and metabolic alkalosis by respiratory acidosis.

Answer to Question 2

ANS: C
The neuromuscular blocking actions of magnesium sulfate can be counteracted with the administration of calcium gluconate. When parenteral magnesium is being administered, an injectable form of calcium, calcium gluconate, should be immediately available.
Potassium phosphate, magnesium chloride, and bicarbonate would not help counter the effects of magnesium toxicity.
