A 32-year old female patient has been taking lorazepam (Ativan) for her anxiety and is brought into the emergency department after taking 30 days' worth at one time. What antagonist for benzodiazepines may be used in this case?
Epinephrine
Atropine
Flumazenil
Naloxone
The Correct Answer is C
Choice A rationale: Epinephrine is not an antagonist for benzodiazepines. It is primarily used in the treatment of anaphylaxis and cardiac arrest.
Choice B rationale: Atropine is not an antagonist for benzodiazepines. It is used to increase heart rate and treat certain types of poisoning.
Choice C rationale: Flumazenil is a specific antagonist for benzodiazepines. It can be used to reverse the sedative effects of benzodiazepine overdose, such as in the case of the patient taking an excessive amount of lorazepam.
Choice D rationale: Naloxone is an opioid antagonist and would not be effective in reversing the effects of lorazepam overdose.

Explanation
Choice A rationale: Donepezil works by enhancing the action of acetylcholine, improving neuronal transmission, so this statement is accurate.
Choice B rationale: Upset stomach is a common side effect of donepezil, and the patient's awareness of this potential side effect indicates understanding.
Choice C rationale: Taking donepezil with food can reduce the risk of stomach upset, so this statement is appropriate.
Choice D rationale: Donepezil helps manage symptoms of Alzheimer's Disease but does not stop the progression or damage to neurons. Further education is needed on the realistic expectations of the medication.
Correct Answer is B
Explanation
Choice A rationale: Selective stimulation of beta2 receptors is less likely to cause hypoglycemia; beta1 receptors are more involved in glucose metabolism.
Choice B rationale: Beta2 receptors are primarily found in the bronchioles of the lungs, and their stimulation leads to improved breathing.
Choice C rationale: Tachycardia is more commonly associated with the selective stimulation of beta1 receptors.
Choice D rationale: Beta2 receptors are not typically involved in the modulation of pain perception.
