Question 1 of 5
Regarding drugs used in the treatment of status epilepsy:
Correct Answer: D
Rationale: Phenytoin controls status epilepticus via anticonvulsant action, not sedation, so that's false. It precipitates in dextrose, only saline-compatible, making that false. Diazepam's effect is short-lived, not long-lasting, so that's incorrect. Phenobarbitone commonly causes respiratory depression, a true statement, due to CNS suppression. Phenytoin's rate is 50 mg/min max. This side effect limits phenobarbitone's use, requiring ventilatory support in status management.
Question 2 of 5
Mark the location of the beginning of the plateau phase on this dose-response relationship curve.
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
The nurse has completed medication education with the patient who is receiving lithium (Eskalith). What is the priority patient outcome?
Correct Answer: B
Rationale: Lithium toxicity (e.g., tremors, confusion) at narrow therapeutic range (0.6-1.2) is life-threatening-knowing signs (e.g., nausea) and prevention (e.g., hydration) is priority, per safety. Work, ADLs, and mood stability follow but aren't immediate risks. Toxicity awareness saves lives, per education.
Question 4 of 5
A 34-year-old man is a chronic alcoholic and is in and out of a rehabilitation center on a monthly basis. His physician administers a blocker of aldehyde dehydrogenase. Which of the following effects is most likely to be exhibited by this patient following administration?
Correct Answer: D
Rationale: Disulfiram, an aldehyde dehydrogenase blocker, is used in alcoholism to deter drinking. When alcohol is consumed, acetaldehyde accumulates, causing nausea . Bradycardia isn't typical; tachycardia may occur with acetaldehyde buildup. Elation and euphoria contradict the aversive intent. Urticaria (E) is possible but less common. Nausea, with flushing and vomiting, creates an unpleasant reaction, reinforcing abstinence. This aligns with disulfiram's mechanism, leveraging acetaldehyde toxicity to modify behavior, distinguishing it from other effects.
Question 5 of 5
A 33-year-old man with a history of asthma comes into the emergency department after getting stung by a bee. The treating physician wants to give epinephrine subcutaneously. Which of the following contraindications to this medication is noted?

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
