Jordan Washington, age 64, has chronic obstructive lung disease
caused by a long history of smoking cigarettes. She is currently
hospitalized because she complains of shortness of breath. His
arterial blood gases are pH 7.24, pCO2 68mmHg, HCO3 25.
A chest x-ray was completed. Mrs. Washington is diagnosed with
pneumonia and an antibiotic was ordered.
Mrs. Washington states she is unsure if she has any known
allergies. Her past medical history indicates she had asthma as a
child. She tells you when she was a child, she experienced itching
after taking a pill, but she cannot recall the name of the
pill.
You start Mrs. Washington's intravenous (IV) and perform a
saline flush. You begin infusing the IV antibiotic. Within three
minutes, she states that her skin itches, and a few minutes later
she begins to complain of tightness in her throat and difficulty
breathing.
