A patient has had an overdose of an intravenous cholinergic drug. The nurse expects to administer which drug as an antidote?

A. A lithium level of 0.9 mEq/L falls within the therapeutic range for lithium, so it is not too low.

B. A lithium level of 0.9 mEq/L is within the therapeutic range for lithium maintenance therapy, which typically ranges from 0.6 to 1.2 mEq/L. Therefore, it is considered therapeutic.
C. Lithium is commonly monitored with blood levels to ensure therapeutic efficacy and to prevent toxicity.
D. A lithium level of 0.9 mEq/L is not too high; it is within the therapeutic range.

A. Diarrhea is not typically associated with ergotamine toxicity. Gastrointestinal symptoms such as nausea and vomiting are more common adverse effects of ergotamine use.
B. Delirium is a potential sign of ergotamine toxicity. At toxic levels, ergotamine can cause central nervous system symptoms such as confusion, hallucinations, and delirium.
C. Hypotension may occur as an adverse effect of ergotamine due to its vasoconstrictive properties. However, hypotension alone may not indicate ergotamine toxicity.
D. Bradycardia is not a typical adverse effect of ergotamine. Ergotamine is more commonly associated with vasoconstriction and can lead to hypertension or tachycardia rather than bradycardia.
