The nurse is obtaining a history from a client who discloses daily use of St. John's Wort in addition to prescription drugs. Which effect of this dietary supplement would most concern the nurse?
It increases the risk of bleeding.
It enhances the effects of all drugs.
It counteracts the effects of central nervous system (CNS) depressants.
It accelerates the metabolism of some drugs.
The Correct Answer is A
a) St. John's Wort is known to increase the risk of bleeding, especially when used with anticoagulant medications. This effect is particularly concerning and may require adjustments in the treatment plan.
b) While St. John's Wort can interact with various drugs, increasing the risk of bleeding is a more immediate concern.
c) St. John's Wort does not counteract the effects of CNS depressants; it may actually enhance the effects of these drugs.
d) St. John's Wort is known to induce the metabolism of some drugs, potentially reducing their effectiveness, but this is not as immediately concerning as the risk of bleeding.
