Question 1 pts
When prescribing lovastatin, what will a provider advise to decrease the risk of
developing muscle toxicity?
Avoid exercise for 2 hours after administration.
Take the medication with an NSAID or other anti-inflammatory drug.
Monitor aspartate aminotransferase (AST) and alanine aminotransferase (ALT).
Substitute grapefruit juice with orange juice.
Grapefruit juice can inhibit the metabolism of certain drugs including statins like
lovastatin. The juice raises drug levels decreasing the intestinal metabolism of
the drug resulting in increased drug levels which increases the risk for adverse
effects such as muscle toxicity. Taking the drug with an anti-inflammatory drug
and avoiding exercise after administration are not supported by science.
Monitoring AST and ALT detects liver toxicity, not muscle toxicity.
Question 2 pts
When prescribing drugs with a narrow therapeutic index, what intervention
does the provider take to decrease risk to the patient?
Monitor the patient’s plasma drug levels at regular intervals.
Order the medication to be administered by the intravenous route.
