2. What is the primary action of angiotensin-converting enzyme (ACE)
g g g g g g g g



inhibitors?
g




A) Block the release of aldosterone
g g g g



B) Decrease the conversion of angiotensin I to angiotensin II
g g g g g g g g



C) Increase sodium reabsorption in the kidneys
g g g g g



D) Increase heart rate g g




Answer: B) Decrease the conversion of angiotensin I to angiotensin II
g g g g g g g g g g




Rationale: ACE inhibitors block the enzyme responsible for converting angiotensin
g g g g g g g g g



I to angiotensin II, which helps lower blood pressure by causing vasodilation and
g g g g g g g g g g g g g



reducing aldosterone secretion.

A) Block dopamine reuptake
g g



B) Increase serotonin levels by inhibiting its reuptake
g g g g g g



C) Inhibit the breakdown of serotonin
g g g g



D) Block norepinephrine receptors
g g




Answer: B) Increase serotonin levels by inhibiting its reuptake
g g g g g g g g




Rationale: SSRIs inhibit the reuptake of serotonin in the brain, leading to
g g g g g g g g g g g



increased levels of serotonin, which helps alleviate symptoms of depression and
g g g g g g g g g g



ganxiety.


5. Which drug is commonly used to reverse the effects of opioid overdose?

g g




Rationale: Naloxone is an opioid antagonist that can reverse the life-threatening
g g g g g g g g g g



respiratory depression caused by opioid overdose. It works by displacing opioids
g g g g g g g g g g g



from their receptors.
