Question 1 of 5
A 29-year-old man who is a known alcoholic is able to purchase phencyclidine from another user of this substance. He takes a 'triple dose' of the substance. Which of the following effects is likely to be observed?
Correct Answer: A
Rationale: PCP overdose (triple dose) causes dissociative effects; eyes remain open , with nystagmus common. Loss of consciousness needs higher doses. Numbness occurs, but open eyes are hallmark. Normal gait and speech (E) contradict ataxia. PCP's profile fits this.
Question 2 of 5
The patient has been receiving amitriptyline (Elavil) for 2 weeks. He tells the nurse he doesn't think this medicine is working, as he is still depressed. What is the best response by the nurse?
Correct Answer: A
Rationale: Amitriptyline, a TCA, needs 4-6 weeks for full antidepressant effect-serotonin/norepinephrine buildup, per pharmacology. ‘Looking better' dismisses feelings. Switching meds is premature-2 weeks is early. Months overstates delay. Weeks to effect educates, setting realistic hope.
Question 3 of 5
A 30-year-old male patient is brought to the ER with the following symptoms attributed to a drug overdose: HR and BP, mydriasis, behavioral excitation, aggressiveness, paranoia, and hallucinations. Of the following drugs, which one is most likely to be responsible for these symptoms?
Correct Answer: A
Rationale: Amphetamine overdose causes sympathomimetic toxicity: elevated heart rate (HR) and blood pressure (BP) from catecholamine release, mydriasis via alpha-adrenergic stimulation, and CNS excitation—aggressiveness, paranoia, and hallucinations—due to dopamine and norepinephrine excess. Ethanol overdose typically depresses CNS, causing sedation, not excitation, despite possible tachycardia. Fentanyl, an opioid, leads to respiratory depression and miosis, opposite to these symptoms. Flunitrazepam, a benzodiazepine, sedates and lowers BP. Marijuana might cause paranoia but not this full sympathomimetic profile. Amphetamine's stimulant properties directly explain the cardiovascular, pupillary, and psychiatric symptoms, making it the most likely culprit in this acute presentation.
Question 4 of 5
A 29-year-old man who is a known alcoholic is able to purchase phencyclidine from another user of this substance. He takes a 'triple dose' of the substance. Which of the following effects is likely to be observed?
Correct Answer: A
Rationale: PCP overdose (triple dose) causes dissociative effects; eyes remain open , with nystagmus common. Loss of consciousness needs higher doses. Numbness occurs, but open eyes are hallmark. Normal gait and speech (E) contradict ataxia. PCP's profile fits this.
Question 5 of 5
What is the administration route of Ondansetron?
Correct Answer: D
Rationale: Ondansetron is typically administered orally, commonly in the form of tablets, orally disintegrating tablets, or liquid solution. The medication is absorbed through the gastrointestinal tract when taken orally, making it an effective route of administration for managing nausea and vomiting. SubQ (subcutaneous), sublingual, and buccal routes are not typical routes of administration for ondansetron.
