A client is admitted to the hospital with an overdose of alprazolam, a benzodiazepine. Which of the following medications should the nurse anticipate administering as an antidote?
Naloxone
Flumazenil
Acetylcysteine
Atropine
The Correct Answer is B
Correct answer: b) Flumazenil
Rationale: Flumazenil is an antidote for benzodiazepine overdose as it reverses its sedative effects by blocking its action on the GABA receptors.
Incorrect choices:
a) Naloxone: This is an antidote for opioid overdose as it displaces opioids from their receptors and restores respiration.
c) Acetylcysteine: This is an antidote for acetaminophen overdose as it replenishes glutathione and prevents liver damage.
d) Atropine: This is an antidote for organophosphate poisoning as it blocks the effects of acetylcholine and relieves bronchoconstriction and bradycardia.

Incorrect choices:
a) Enter the client's name and date of birth.: This is not a required step when obtaining medication from the automated dispensing system, but it is a required step when administering medication to the client to verify their identity.
b) Scan the barcode on the medication label.: This is not a required step when obtaining medication from the automated dispensing system, but it is a required step when administering medication to the client to verify its accuracy.
c) Enter the prescriber's name and license number.: This is not a required step when obtaining medication from the automated dispensing system, but it may be required when documenting medication administration in some facilities.
Correct Answer is D
Explanation
Correct answer: d) "Methadone will block the effects of opioids if I relapse."
Rationale: Methadone is an opioid agonist that blocks the effects of opioids by occupying their receptors and preventing them from binding. This reduces the risk of overdose and relapse by eliminating the reward or pleasure of using opioids.
Incorrect choices:
a) "Methadone will help me stop craving opioids.": This is incorrect as methadone does not eliminate cravings for opioids, but it reduces them by preventing withdrawal symptoms.
b) "Methadone will make me feel euphoric like opioids do.": This is incorrect as methadone does not produce euphoria or sedation like opioids do, but it maintains a steady state of opioid tolerance and dependence.
c) "Methadone will cause me to have withdrawal symptoms when I stop taking it.": This is incorrect as methadone prevents withdrawal symptoms by providing a long-acting opioid substitute. However, methadone itself can cause dependence and withdrawal if discontinued abruptly, so it should be tapered off gradually under medical supervision.
