Which of the following opioids would be contraindicated in the patient with acute myocardial infarction?

Correct Answer: D

Rationale: The correct answer is D: Morphine. Morphine is contraindicated in acute myocardial infarction due to its potential to cause hypotension and respiratory depression, which can worsen the patient's condition. Morphine can also increase myocardial oxygen demand, further compromising the patient's heart function. Rationale: - A: Amitriptyline is a tricyclic antidepressant and is not typically contraindicated in acute myocardial infarction. - B: Acetaminophen is a non-opioid analgesic and is generally safe to use in patients with acute myocardial infarction. - C: Haloperidol is an antipsychotic medication and is not typically contraindicated in acute myocardial infarction.

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.

Correct Answer: D

Rationale: The correct answer is D: Amphetamine. The signs and symptoms described are consistent with amphetamine use, including increased heart rate, agitation, and dilated pupils. Cocaine can cause similar symptoms but typically leads to a shorter duration of effects compared to amphetamines. Marijuana and LSD are less likely to cause the specific signs and symptoms mentioned. Amphetamine's stimulant properties align with the patient's presentation, making it the most likely culprit.
