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: Abstinence syndrome (withdrawal) from alcohol is characterized by symptoms such as muscle cramps, tremors, and tachycardia.
Choice B rationale: Hyperventilation, chest pain, and ptosis are not typical manifestations of alcohol withdrawal.
Choice C rationale: Increased urination, dry cough, and hypothermia are not characteristic of alcohol withdrawal.
Choice D rationale: Epistaxis, ascites, and exophthalmos are not specific to alcohol withdrawal and may indicate other health issues.
Correct Answer is D
Explanation
Choice A rationale: Managing dry-mouth symptoms is not the greatest teaching priority for a patient prescribed varenicline.
Choice B rationale: Increasing fiber in the diet to reduce constipation is not the greatest teaching priority for a patient prescribed varenicline.
Choice C rationale: The greatest teaching priority for a patient prescribed varenicline is to report thoughts of self-harm. Varenicline is a medication used for smoking cessation, and there have been reports of neuropsychiatric symptoms, including suicidal ideation.
Choice D rationale: Teaching about the decreased pleasurable effect of nicotine is important but not the greatest priority compared to ensuring the patient's safety.
