Question 1 of 5
The nurse teaches a class about medication used during pregnancy to pregnant women. The nurse determines that additional instruction is required when a class participant makes which response?
Correct Answer: A
Rationale: Drugs harm fetuses across trimesters-first (organogenesis) is critical, but later effects (e.g., growth) occur, so this needs correction. Avoiding OTC drugs is wise-many risk harm. Teratogens cause death or defects, true. Breast milk transfers drugs, also true. First-trimester-only harm misstates risk, requiring reteaching.
Question 2 of 5
A 39-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 and the patient becomes violently ill with nausea, vomiting, chills, sweats, and hyperventilation. The same reaction occurs 1 week later after medication administration and was felt to be intolerable by the patient. Which of the following is the next best course of action to take?
Correct Answer: C
Rationale: The patient's severe reaction to disulfiram (aldehyde dehydrogenase blocker) suggests alcohol exposure, making it intolerable. Option continues the issue. Option intentionally triggers the reaction, unethical. Option , discontinuing disulfiram and starting naltrexone, is correct-naltrexone reduces alcohol cravings via opioid receptor antagonism, offering a safer alternative. Option , alprazolam, treats anxiety but not alcoholism. Option (E), psychotherapy, lacks immediate pharmacotherapy. Naltrexone addresses the root addiction without aversive effects, aligning with the patient's intolerance and chronic relapse pattern.
Question 3 of 5
A 27-year-old man with HIV disease and hepatitis B is hospitalized for treatment of his hepatitis B. He has begun on intravenous treatment with interferon. After administration, he develops fever, chills, and myalgias. Physical examination reveals that the lungs are clear to auscultation bilaterally. What is the most likely explanation for this reaction?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
A 22-year-old woman ingests an entire bottle of acetaminophen in an attempted suicide. She unexpectedly feels well; and when her boyfriend discovers what she has done, he takes her to the emergency department. Which of the following drugs should be given in the ER?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
Modest improvement in the memory of patients with Alzheimer's disease may occur with drugs that increase transmission at which of the following receptors?
Correct Answer: B
Rationale: Alzheimer's disease features cholinergic neuron loss, impairing memory via reduced acetylcholine signaling in the hippocampus and cortex. Drugs like acetylcholinesterase inhibitors (e.g., donepezil) boost cholinergic transmission by preventing acetylcholine breakdown, modestly improving memory and cognition in early stages. Adrenergic enhancement (e.g., via norepinephrine) affects arousal, not memory directly. Dopaminergic drugs treat Parkinson's, not Alzheimer's cognitive deficits. GABAergic drugs (e.g., benzodiazepines) inhibit cognition, worsening memory. Serotonergic agents target mood, not memory. The cholinergic deficit is a hallmark of Alzheimer's pathology, and augmenting this system remains a primary therapeutic strategy, validated by clinical outcomes.
