Question 1 of 5
The nurse provides care for elders in an assisted living facility. What does the nurse assess as a primary contributing factor for drug toxicity in the elderly?
Correct Answer: B
Rationale: Dehydration, common in elders from reduced thirst, lowers drug clearance (e.g., renal function drops), risking toxicity-key in pharmacokinetics. Alcohol abuse varies, not primary. Constipation affects excretion less than fluid status. Stomach acid decreases, not increases, with age. Dehydration's impact on volume and clearance drives toxicity risk.
Question 2 of 5
A 32-year-old anesthesiology resident injects himself with ketamine after he is served with divorce papers from his wife. In addition to being suspended from his hospital because of his actions, he would likely exhibit which of the following behaviors?
Correct Answer: D
Rationale: Ketamine, an NMDA antagonist, causes dissociative anesthesia. Slurred speech is correct-users often exhibit altered speech, disorientation, and motor impairment. Hypersensitivity to pain contradicts ketamine's analgesia. Loss of consciousness occurs at high doses, but self-injection suggests sub-anesthetic use. Normal gait is unlikely due to ataxia. Tranquil affect (E) doesn't fit agitation or dissociation. Slurred speech reflects ketamine's CNS depression, consistent with abuse scenarios.
Question 3 of 5
A 39-year-old man with long-standing allergies has no health insurance and simply takes over-the-counter diphenhydramine for symptom relief. He has no other medical problems but uses this medication up to four times per day. Which of the following effects of this medication is possible to be experienced by this patient?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
An 18-year-old man is brought to the emergency department by a friend after smoking crack cocaine because he was 'acting funny.' His temperature is 38°C (100.4°F), pulse is 110 beats/minute, and he appears agitated. Which of the following is an effect of cocaine intoxication?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
Which of the following agents may cause tremors as a side effect and, thus, should be used with caution in patients with Parkinson's disease, even though it is also indicated for the treatment of dementia associated with Parkinson's disease?
Correct Answer: C
Rationale: Rivastigmine, an acetylcholinesterase inhibitor, treats Parkinson's disease dementia by enhancing cholinergic function, improving cognition. However, increased acetylcholine can exacerbate tremors, a core Parkinson's symptom, by disrupting dopamine-acetylcholine balance in the basal ganglia, requiring cautious use. Benztropine, an anticholinergic, reduces tremors, not causes them. Rotigotine, a dopamine agonist, improves motor symptoms. Dimethyl fumarate manages MS, not Parkinson's dementia, and lacks tremor association. Rivastigmine's benefit in dementia must be weighed against its potential to worsen tremors, making it the drug needing careful monitoring in this context.
