单项选择题
A client is admitted for an overdose of amphetamines. When assessing this client, the nurse should expect to have which of the following findings
A．Tension and irritability.
B．Slow pulse.
C．Hypotension.
D．Constipation.
答案
参考答案：A
解析：An amphetamine is a nervous system stimulant that is subject to abuse because of its ability to produce wakefulness and euphoria. An overdose increases tension and irritability. Options B and C are incorrect because amphetamines stimulate norepinephrine, which increases the heart rate and blood flow. Diarrhea is a common adverse effect, so option D is incorrect.
