Question 1 of 5
A 3-year-old girl was found by her mother chewing on some weeds in their flower garden. The mother rushed her to the hospital along with a portion of the weed. The emergency department physician identifies the weed as deadly nightshade, which contains atropine. Which of the following physiologic changes will be expected because of this patient's atropine exposure?
Correct Answer: B
Rationale: Deadly nightshade (atropine) blocks muscarinic receptors. Decreased gastric acid secretion is correct-atropine inhibits parasympathetic stimulation of parietal cells. Bradycardia is wrong; tachycardia occurs. Increased bronchial secretions and salivation decrease, as does miosis (E)-pupils dilate. This anticholinergic effect explains the expected change in this poisoning.
Question 2 of 5
A 63-year-old man presents to the emergency department with altered mental status after ingesting an entire bottle of acetaminophen. The patient's heart rate is 120 beats/minute, blood pressure is 100/58 mm Hg, and respiration rate is 28/minute. His aspartate aminotransferase and alanine aminotransferase are 4,128 IU and 3,978 IU, respectively. What is the most appropriate treatment for this patient?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
A 25-year-old woman with myoclonic seizures is well controlled on valproate. She indicates that she is interested in becoming pregnant in the next year. With respect to her antiepilepsy medication, which of the following should be considered?
Correct Answer: B
Rationale: Valproate controls myoclonic seizures but is teratogenic, linked to neural tube defects (e.g., spina bifida) and cognitive deficits in offspring, posing significant pregnancy risks. Switching to lamotrigine, effective for myoclonic seizures and safer (lower teratogenicity), is recommended preconception after titration. Continuing valproate unchanged ignores fetal harm. Adding another drug increases complexity without addressing valproate's risks. Lowering the dose may compromise seizure control. Lamotrigine's efficacy and better pregnancy safety profile, per guidelines, make it the best consideration.
