A nurse is collecting data on a client who reports acute pain at a level of 7 on a scale of 0 to 10. Which of the following findings should the nurse expect?

A. Acute pain usually stimulates the sympathetic nervous system, which can increase respiratory rate, not decrease it. A decreased rate is more associated with opioid use or central nervous system depression. B. Pain typically causes tachycardia, not bradycardia, as part of the stress response. C. Acute pain activates the sympathetic nervous system, leading to increased heart rate, vasoconstriction, and elevated blood pressure (hypertension). This is a common physiological response to moderate to severe pain. D. Acute pain does not directly cause hypoglycemia; instead, it can cause hyperglycemia due to stress-induced release of cortisol and catecholamines.
