Question 1 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 2 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 3 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.
Question 4 of 5
A client calls the clinic and tells the nurse that she has missed taking several of her contraceptive pills during the current cycle. What is the best instruction for the nurse to give the client?
Correct Answer: D
Rationale: Missing oral contraceptive pills reduces their efficacy, increasing pregnancy risk. If several pills are missed , the hormonal protection is compromised, requiring an alternative method (e.g., condoms) for the cycle's remainder to prevent conception. Immediate pregnancy testing assesses outcome, not prevention. Suggesting a new method addresses future planning, not current risk. Choice C underestimates the risk, as even fewer than three missed pills can disrupt efficacy, depending on timing. The nurse's best instruction (D) ensures immediate protection, aligning with contraceptive guidelines for missed doses, prioritizing safety and efficacy.
Question 5 of 5
The client receives estrogen for prostate cancer. He asks the nurse why he is receiving a female hormone. What is the best response by the nurse?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
