Correct Answer is A

Explanation

Choice A reason: Metabolic alkalosis is indicated by a high pH and a high HCO3 level. In this case, the pH is 7.5, which is above the normal range of 7.35-7.45, and the HCO3 is 32 mEq/L, which is above the normal range of 22-26 mEq/L.

Choice B reason: Respiratory acidosis is characterized by a high CO2 level and a low pH, which is not the case here as the CO2 is normal and the pH is high.

Choice C reason: Respiratory alkalosis typically presents with a low CO2 level and a high pH. Since the CO2 is normal, this condition does not fit the patient's ABG results.

Choice D reason: Metabolic acidosis would present with a low pH and a low HCO3 level. Given that both the pH and HCO3 are high, metabolic acidosis is not the correct diagnosis.

A. Atropine B. Protamine C. Vitamin K D. Epinephrine

Correct Answer is C

Explanation

Choice A reason: Atropine is used to treat bradycardia and is not an antidote for warfarin overdose.

Choice B reason: Protamine is used to reverse the eﬀects of heparin, not warfarin.

Choice C reason: Vitamin K is the antidote for warfarin overdose as it helps in the synthesis of clotting factors that warfarin inhibits.

Choice D reason: Epinephrine is used for severe allergic reactions and cardiac arrest, not as an antidote for warfarin overdose.
