Which of the following drugs was most likely prescribed for the woman described in the text?

Correct Answer: C

Rationale: Bupropion is a medication that is commonly used to treat depression, ADHD, and smoking cessation. Given the woman's symptoms of feeling fearful, helpless, and worried, as well as her difficulty organizing thoughts and smoking habit, bupropion would be a suitable choice as it can address both depressive and attention deficit disorders, as well as aid in smoking cessation.

Correct Answer: D

Rationale: The patient self-injected what he believed to be heroin, which is commonly sold on the street. Fentanyl is a potent synthetic opioid that is often mixed with or sold as heroin due to its powerful effects. Therefore, the patient most likely took Fentanyl, as it is frequently associated with street drugs like heroin.

Correct Answer: A

Rationale: In this scenario, the correct answer is A) Morphine, which would be contraindicated in the patient. Morphine is an opioid analgesic that can cause respiratory depression, sedation, and potential overdose, especially in patients with compromised respiratory function or history of opioid abuse. B) Fentanyl is a potent opioid analgesic commonly used in anesthesia and chronic pain management. It is often preferred in patients who cannot tolerate other opioids due to its potency and rapid onset of action. C) Buprenorphine is a partial opioid agonist used in the treatment of opioid addiction and chronic pain. It has a ceiling effect on respiratory depression, making it a safer option in patients at risk for opioid overdose. D) Pentazocine is a mixed opioid agonist-antagonist used for moderate to severe pain. It has a lower risk of respiratory depression compared to full opioid agonists like morphine. However, it can precipitate withdrawal symptoms in patients who are opioid-dependent. Educationally, understanding the contraindications and appropriate use of opioids is crucial for healthcare professionals, especially in the context of pain management and patient safety. It is essential to consider individual patient factors, such as respiratory status, opioid tolerance, and history of substance abuse, when selecting the most appropriate opioid for pain control.

Correct Answer: D

Rationale: Meperidine is a commonly used opioid analgesic that is often used in detoxification programs due to its ability to help manage withdrawal symptoms. In this case, the patient was undergoing a detoxification program supervised by surgery, and a drug was administered intravenously. Meperidine is a likely choice as it can help alleviate withdrawal symptoms and manage pain during the detoxification process.

Correct Answer: B

Rationale: The symptoms described in the scenario, such as elevated mood, rapid speech, muscle twitching, and dilated pupils, are consistent with the effects of marijuana use. Increased heart rate is a common physiological response to smoking marijuana due to the drug's impact on the cardiovascular system. Additionally, euphoria and uncontrollable laughter are typical psychological effects of marijuana use, further supporting the choice of increased heart rate as the correct answer.
