Which of the following drugs most likely caused the patient's high blood pressure?

Correct Answer: B

Rationale: The correct answer is B: Norepinephrine. Norepinephrine is a neurotransmitter and a medication that can increase blood pressure by constricting blood vessels. Atomoxetine (A) is used to treat ADHD and does not typically cause high blood pressure. Phenylephrine (C) is a decongestant that can raise blood pressure temporarily. Guanfacine (D) is a medication used to lower blood pressure, so it is unlikely to be the cause of the patient's high blood pressure.

Correct Answer: C

Rationale: The correct answer is C: Guanfacine. Guanfacine is commonly prescribed for children with irritability and self-injurious behavior due to its effectiveness in treating symptoms of ADHD and disruptive behavior disorders. It helps regulate impulse control and reduce aggression. Dextroamphetamine and Methylphenidate (Choices A and B) are stimulant medications primarily used for ADHD but may not directly address irritability and self-injurious behavior. Bupropion (Choice D) is an antidepressant and not typically the first choice for managing irritability and self-injurious behavior in children.

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: 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: 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.
