Final answer:
Decreased blood pressure is not a typical physiologic indicator of pain in an infant, as this would contradict the expected increase in blood pressure due to the body's fight-or-flight response.
Step-by-step explanation:
A nurse assessing the pain level of an infant should consider certain physiologic indicators of pain. Typical signs include an increased heart rate, increased respiratory rate, and muscle tension. However, it is not typical to observe a decrease in blood pressure as a direct response to pain. In the stress response to pain, you would expect to see increased blood pressure due to the body's fight-or-flight response, not a decrease. Therefore, of the options provided, a decrease in blood pressure would not be a typical physiologic indicator of pain in an infant.
Other Relevant Facts:
- During the sympathetic fight-or-flight response, one would expect to see increased blood pressure, not decreased.
- Decreasedintestinal peristalsis can occur as the body diverts energy and resources elsewhere.
- Increased blood volume may occur due to retention of fluids during stress responses.
