According to the Institute for Safe Medication Practices (ISMP) which of the following medications is considered a high-alert/high-risk medication?

Acetaminophen, even in extra strength, is generally considered safe when used as directed and is not classified as a high-alert medication. While overdosing can lead to serious liver damage, the risk of significant harm is lower compared to high-alert medications, which are often involved in severe adverse events due to dosing errors.

Furosemide is a diuretic used to treat fluid retention and high blood pressure. While it has potential side effects and requires careful monitoring, it is not classified as a high-alert medication. The risks associated with furosemide do not meet the stringent criteria set by ISMP for high-alert medications.

Ceftriaxone is an antibiotic that can cause serious adverse effects, particularly in specific populations (like neonates). However, it is not designated as a high-alert medication according to ISMP. The classification focuses on medications with a higher incidence of severe consequences from errors, which does not include ceftriaxone.
