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.

Answer and Explanation

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.

Correct Answer is B

Explanation

A) Antibiotic resistance is not a reason to adjust the dose of gentamicin.

B) Gentamicin is primarily excreted by the kidneys. In the presence of renal disease, the dose may need to be adjusted to prevent toxicity.

C) Liver disease does not directly impact the metabolism or excretion of gentamicin, so it is not typically a factor in dose adjustment.

D) Interpatient variation alone may not prompt a specific dose adjustment; individual patient factors, especially renal function, are crucial in determining gentamicin dosage.

A. "Oral acyclovir may be used during pregnancy." B. "Intravenous antiviral agents will be used if an outbreak occurs." C. "Topical acyclovir must be used to control outbreaks." D. "Antiviral medications are not safe during pregnancy."

Correct Answer is A

Explanation

a. This is the correct answer. Oral acyclovir is considered safe during pregnancy and may be used to suppress outbreaks of genital herpes in pregnant women.

b. Using intravenous antiviral agents is typically reserved for severe cases and is not the first-line approach for suppressing outbreaks in pregnant women.

c. While topical acyclovir can be used for genital herpes outbreaks, it is not typically the first choice for suppression during pregnancy.

d. This statement is not accurate. Some antiviral medications, including oral acyclovir, are considered safe during pregnancy when the benefits outweigh the risks, especially in cases where there is a history of recurrent genital herpes.
