Which of the following opioids did the patient most likely take?

Correct Answer: D

Rationale: The correct answer is D: Fentanyl. Fentanyl is a potent synthetic opioid commonly used for severe pain management. The patient most likely took Fentanyl due to its high potency, fast onset of action, and effectiveness in managing severe pain. Buprenorphine (A) is a partial opioid agonist used for opioid addiction treatment, not typically for severe pain. Morphine (B) is a strong opioid but less potent than Fentanyl and not commonly used for severe pain management. Pentazocine (C) is a mixed opioid agonist-antagonist and not as potent as Fentanyl for severe pain relief.

Correct Answer: D

Rationale: Sure! Meperidine is the most likely drug administered because it is a synthetic opioid analgesic commonly used for pain relief. It is frequently administered in healthcare settings for moderate to severe pain. Amitriptyline is a tricyclic antidepressant, Indomethacin is a nonsteroidal anti-inflammatory drug, and Fluoxetine is a selective serotonin reuptake inhibitor, none of which are typically used for immediate pain relief like Meperidine.

Correct Answer: D

Rationale: Naltrexone is the correct answer as it is an opioid receptor antagonist used to reduce alcohol cravings and dependence. It works by blocking the pleasurable effects of alcohol, helping individuals to avoid consuming it. Diazepam (A) is a benzodiazepine used for anxiety, not alcohol dependence. Clonidine (B) is an alpha-2 agonist used for hypertension, not alcohol dependence. Disulfiram (C) is an aversion therapy drug that causes unpleasant effects when alcohol is consumed, not for avoidance from dependence.

Correct Answer: D

Rationale: The correct answer is D: LSD. LSD is a hallucinogenic drug that can cause hallucinations, altered perceptions, and potentially dangerous behaviors leading to accidents or self-harm, but it does not directly cause fatal overdose. Heroin (A) is an opioid that can depress the central nervous system and cause respiratory depression leading to death. Gamma-hydroxybutyric acid (B) is a central nervous system depressant that can lead to respiratory depression and death. Ketamine (C) is a dissociative anesthetic that can cause respiratory depression and other adverse effects, but it is less likely to directly cause fatal overdose compared to heroin or GHB.

Correct Answer: C

Rationale: Rationale: 1. The symptoms described are likely related to benzodiazepine withdrawal. 2. Diazepam is a benzodiazepine commonly used for anxiety, and sudden cessation can lead to withdrawal symptoms like tremors, anxiety, and seizures. 3. Heroin withdrawal presents with flu-like symptoms, Phencyclidine withdrawal causes agitation and hallucinations, and Amphetamine withdrawal results in fatigue and depression. 4. Therefore, the correct answer is C, Diazepam, as it aligns with the symptoms described.
