Final answer:
Three maladaptive systemic responses to diminished cardiac output are increased heart rate but decreased blood pressure, decreased urine output, and inadequate blood flow to the tissues.
Step-by-step explanation:
Three maladaptive systemic responses to diminished cardiac output are:
- Increased heart rate but decreased blood pressure, which can lead to circulatory shock.
- Decreased urine output, which is cause for concern.
- Inadequate blood flow to the tissues, leading to cellular metabolism problems.
