Question 1 of 5
Which statement is accurate regarding attention-deficit hyperactivity disorder (ADHD)?
Correct Answer: B
Rationale: ADHD in girls often presents as anxiety/withdrawal, versus boys' hyperactivity-per research-though diagnosis favors boys. It's not bipolar-mania/depression differ. Boys dominate diagnosis stats. It's early, not late, onset. Gender presentation accuracy reflects ADHD nuance.
Question 2 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 3 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 4 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: Estrogen suppresses androgen production , starving androgen-dependent prostate cancer. Choice A misstates cell death. Choice B overstates testosterone elimination. Choice D misattributes nutrient blockade. C explains the hormonal mechanism accurately, making it the best response.
Question 5 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: Cocaine intoxication (agitation, tachycardia, fever) causes vasoconstriction , via sympathetic stimulation, raising BP and temperature. Hypercoagulability occurs but isn't primary. Hypocoagulability and hypothermia oppose effects. Vasodilation (E) is wrong. This drives his symptoms.
