Introductory scenario An 87-year-old woman with dementia lives in a nursing facility. A nurse notices that she has been Coughing frequently and seems warm to the touch. She performs an evaluation on the woman and confirms a fever with a dry cough. She also notices that her throat seems inflamed and irritated.

The nurse ensures that the woman is comfortable and returns to the nursing station to review that patient's chart.

The nurse calls the physician, worried that the patient may be developing pneumonia again. Continue to questions Chapter 4 Adaptive Immunity

Explanation / Answer

Answer:

1. (B) Complete Blood Count (CBC) (Hematology)

CBC (complete blood count) evaluates the type and number of white blood cells; results may indicate that an infection is present. An individual's white blood cell count can often give a hint as to the severity of the pneumonia and whether it is caused by bacteria or a virus. An increased number of neutrophils, one type of WBC, is seen in most bacterial infections, whereas an increase in lymphocytes, another type of WBC, is seen in viral infections, fungal infections, and some bacterial infections (like tuberculosis).

2. (C) Yes, a possible bacterial infection is indicated.

The CBC result shows an increased WBC count indicating an infection while an increased percentage of neutrophils and absolute neutrophils suggests a probable bacterial infection.
