Final answer:
When caring for a client who has had a heroin overdose, the nurse should expect a high temperature, increased respiratory rate, and constricted or pinpoint pupils.
Step-by-step explanation:
When caring for a client who has had a heroin overdose, the nurse should expect certain findings. In this case, the nurse should expect a high temperature (option A) due to the body's response to the drug. The respiratory rate may be increased (option B) in order to compensate for decreased oxygenation. The pupils may be constricted or pinpoint (option C) due to the effect of opioids on the autonomic nervous system. Severe abdominal cramping (option D) is not typically associated with a heroin overdose. Therefore, the nurse should expect options A, B, and C in this scenario.
