Sickle Cell Disease Assessment Questions

A

History
* ask about previous crisises, what let to the crisis, severity, and usual management
* explore recent contact with ill people and activities to determine what caused the current crisis; ask about signs and symptoms of infection
* review all activities and events during the past 24hrs, including food and fluid intake, exposure to temperature extremes, drugs taken, exercise, trauma, stress, recent airplane travel, and use of alcohol, tobacco, or other recreational drugs
* ask about changes in sleep and rest patterns, ability to climb stairs, and any activity that induces shortness of breath
* assess the patient’s perceived energy level using a scale ranging from 0 to 10 (0=not tired with plenty of energy; 10= total exhaustion) to assess the degree of fatigue
