Question 2 of 5
Which of the following is the antidote for Heparin?
Correct Answer: A
Rationale: Protamine sulfate is the antidote for Heparin. Heparin is an anticoagulant used to prevent blood clotting. Protamine sulfate works by binding to heparin, neutralizing its anticoagulant effects. Vitamin K is not the antidote for Heparin; it is used to reverse the effects of warfarin, another type of anticoagulant. Naloxone is an opioid antagonist used to reverse the effects of opioids, and

Question 3 of 5
Which drug undergoes extensive first-pass hepatic metabolism?
Correct Answer: C
Rationale: Propranolol undergoes extensive first-pass metabolism in the liver. When administered orally, propranolol is extensively metabolized by the liver before reaching systemic circulation, leading to reduced bioavailability. This process is known as first-pass hepatic metabolism, which significantly affects the drug's effectiveness and necessitates higher oral doses compared to other routes of administration.

Question 5 of 5
Which of the following diuretics inhibits sodium reabsorption in the kidneys while sparing K+ and hydrogen ions?
Correct Answer: A
Rationale: Spironolactone is classified as a potassium-sparing diuretic. It works by inhibiting sodium reabsorption in the kidneys while promoting the retention of potassium and hydrogen ions. This mechanism of action helps in reducing fluid retention without causing excessive loss of potassium, which is a common side effect of other diuretics.
