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

Dobutamine

Atropine sulfate

Atenolol

Bethanechol

Answer and Explanation

The Correct Answer is B

A.   Dobutamine is a sympathomimetic drug used to increase cardiac output in conditions such as heart failure. It is not an antidote for cholinergic drug overdose.
B.   Atropine sulfate is the antidote for cholinergic drug overdose. It acts as a competitive antagonist to acetylcholine at muscarinic receptors, counteracting the effects of excessive cholinergic stimulation.
C.   Atenolol is a beta-blocker used to manage hypertension and certain cardiac conditions. It is not an antidote for cholinergic drug overdose.
D.   Bethanechol is a cholinergic agonist used to stimulate bladder contractions in urinary retention. It is not an antidote for cholinergic drug overdose; in fact, it would exacerbate cholinergic effects.

Correct Answer is D

Explanation

A. "Increase the dosage to twice daily.": Changing the dosage should only be done under the guidance of the prescriber based on clinical assessment, not in response to perceived lack of improvement.
B. "Take the medication on an empty stomach for improved absorption.": While taking donepezil with or without food may affect absorption, this instruction is not directly related to the timing of improvement in symptoms.
C. "It takes time for the cure to take effect.": Alzheimer's disease cannot be cured, and this statement may provide false hope to the patient's daughter.
D. "It may take up to 6 weeks to see an improvement.": This response provides accurate

information about the expected timeline for therapeutic effects of donepezil and encourages patience in observing improvement.

A. Monitor the patient's respiratory rate B. Ensure naloxone is readily available C. Report the error to the facility through the proper paperwork D. Inform the patient's health care provider E. Document the dose of morphine given by the MedSurg nurse

Correct Answer is ["A","C","D","E"]

Explanation

A. Monitor the patient's respiratory rate: It's essential to monitor the patient for any adverse effects of morphine administration, particularly respiratory depression.
B. Ensure naloxone is readily available: While naloxone is an antidote for opioid overdose, administering it would depend on the patient's response and any signs of opioid toxicity, which may not be evident at this time.
C. Report the error to the facility through the proper paperwork: Reporting the medication error is crucial for documentation, investigation, and implementation of corrective actions.
D. Inform the patient's health care provider: The healthcare provider should be notified of the medication error to ensure appropriate follow-up and monitoring of the patient.
E. Document the dose of morphine given by the MedSurg nurse: Documenting the medication administration accurately is essential for the patient's medical record and continuity of care.
