Mar 2-4, 2023

Select two of the following questions for your discussion response. Indicate which questions you have chosen using the format displayed in the "Discussion Forum Sample."

Scenario

Mr. K.P. is a 71-year-old male, who presents to your office with a 3-day history of more than 103F with chills. The patient reports, "I don’t feel well, and I think that I may have the flu." He also complains of "some painful bumps on my fingers and toes that came on last night." He denies IVDA. When asked about recent medical or dental procedures, he responds: "I had an infected tooth removed about 2 weeks ago." He does not recall receiving any antibiotics either prior to or after the procedure.

PMH:

Asthma since childhood

Rheumatic fever as a child x 2 with mitral valve replacement 2 years ago

HTN x 20 years

DM type 2, x 9 years

COPD x 4 years

H/O tobacco abuse

Alcoholic liver disease

Urinalysis: The urine was pale yellow, clear, and negative for proteinuria and hematuria. A urine toxicology screen was also negative.

ECG: Normal

Transthoracic ECHO: A 3-cm vegetation on the aortic valve was observed. No signs of ventricular hypertrophy or dilation were seen.

Blood Cultures: 3 of 3 sets (+) for Streptococcus viridans (collection times 1030 Tuesday, 1230 Tuesday, 1345 Tuesday)
