Central and Peripheral Nervous System Drugs Questions
Question 1 of 5
Which of the following analgesic drugs would be contraindicated for the patient with postoperative adynamic ileus?
Correct Answer: B
Rationale: The correct answer is B: Morphine. Postoperative adynamic ileus is characterized by delayed gastric emptying and reduced intestinal motility. Morphine can exacerbate these symptoms by causing further gastrointestinal motility issues, leading to potential complications such as bowel obstruction. Acetaminophen (A), Ibuprofen (C), and Ketorolac (D) do not have significant effects on gastrointestinal motility and are therefore safer choices for patients with postoperative adynamic ileus.
Question 2 of 5
Withdrawal from which of the following drugs most likely caused the patient's seizure?
Correct Answer: D
Rationale: The correct answer is D: Heroin. Heroin withdrawal can lead to seizures due to the sudden decrease in brain activity when the drug is removed. This causes an imbalance in neurotransmitters, increasing the risk of seizures. LSD (A) and cannabis (B) are not associated with seizure risk during withdrawal. Alprazolam (C) withdrawal can cause seizures but is less common compared to heroin withdrawal.
Question 3 of 5
Which of the following drugs most likely caused the patient's signs and symptoms?
Correct Answer: C
Rationale: The correct answer is C: Phencyclidine. PCP is a dissociative anesthetic that can cause hallucinations, agitation, and violent behavior. The patient's signs and symptoms align with the effects of PCP use. Cocaine (A) typically causes increased energy and alertness, heroin (B) causes sedation and respiratory depression, and LSD (D) causes hallucinations and altered perceptions, but these do not match the patient's presentation.
Question 4 of 5
Which of the following neurotransmitters most likely mediated the effects of the drug in this patient?
Correct Answer: B
Rationale: The correct answer is B: Serotonin. Given the drug's effects, which are likely related to mood regulation and emotional stability, serotonin is the most likely neurotransmitter involved. Serotonin plays a key role in mood, anxiety, and depression. Acetylcholine (A) is more related to muscle movement and memory. Norepinephrine (C) is associated with the fight-or-flight response. GABA (D) is an inhibitory neurotransmitter, primarily involved in reducing neuronal excitability and promoting relaxation, not mood regulation.
