Nurses taking care of children with pain should understand that the pain stimulates the adrenergic nervous system, which will result in which physiologic change?
1. Hypotension
2. Pupil constriction
3. Increased perspiration
4. Bradycardia
3
Rationale:
1. In acute pain, hypertension, not hypotension, occurs.
2. Pupil dilation occurs with acute pain.
3. Acute pain stimulates the adrenergic nervous system and results in physiologic changes, including tachycardia, tachypnea, hypertension, pupil dilation, pallor, increased perspiration, and increased secretion of catecholamine and adrenocorticoid hormones.
4. Bradycardia does not occur with acute pain. The child would experience tachycardia as the adrenergic nervous system was stimulated.
