A patient comes to the emergency department complaining of dyspnea. Based on an analysis of the data provided, what should the nurse suspect is occurring with this patient?
1. pancytopenia
2. chronic bacterial infections
3. a respiratory infection
4. a hypersensitivity response
Correct Answer: 4
The eosinophils (normal 1%–4%) and basophils (normal 0.5%–1%) respond in hypersensitivity responses. The lab values and dyspnea suggest a hypersensitivity response. Pancytopenia would be indicated by very low levels of the laboratory values. A respiratory or chronic bacterial infection would show increases in the WBC (normal 4,000–10,000 per mm3), neutrophils (normal 55%–70%), monocytes (normal 2%–8%), and lymphocytes (normal 20%–40%).
