Exercise 19

• In the preceding example, what if the first defining characteristic (temperature fluctuations) was not present and you had only cyanotic nail beds, pallor and slow capillary refill as cues? Could you conclude that Ineffective Thermoregulation is causing those signs! What other explanations might there be for cyanotic nail beds, pallor, and slow capillary refill?
• What if the last defining characteristic was present without the first one? What could cause tachycardia? Do you see the importance of using clusters rather than individual cues?
