Sepsis-Presence of pathogenic organisms or their toxins in the blood and tissues with a resulting systemic inflammatory response consider obtaining serum sepsis markers (lactate, procalcitonin, others) to help stratify the sickest children.TestPossible findingsCBC with WBC differentialBacterial or viral shiftBlood cultureBacteremia (presence of bacteria in the blood) usually sustained in sepsisUrinalysis (UA) and urine culture and sensitivity via transurethral catheter or suprapubic tapIn UTI, pyelonephritis‒ WBC, bacteria, urine culture positive for the offending organisms LP for CSF analysis and culturePleocytosis (WBC in CSF) and other findings consistent with bacterial or viral meningitisChest x-ray (CXR)To assist in diagnosis of pneumoniaStool culture, fecal WBC count, if diarrhea presentTo assist in the diagnosis of shigella or other forms of infectious diarrhea

- A 78 Year-old Woman…• With a 30-year history of hypertension and dyslipidemia and a 10-year history of type 2 diabetes presents with suspected acute coronary syndrome. She is most likely to report a recent onset of
A. Retrosternal chest pain with radiation to the left arm. B. Syncope. C. Unusual fatigue. D. Nausea and vomiting
unusual fatigue (70% of women) she is an older woman with a high cardiovascular risk nausea and vomiting is not specific to cardiac disease
If unable to palpate the PMI?
position in the left lateral decubitus position
S1
Lubdub” Heard nearly simultaneous with the carotid upstroke
S2
Marks the end of systole. Produced by events surrounding the closure of the aortic and pulmonic valves
Physiologic split S2
Split increases on patient inspiration. Found in the majority of adults
Pathologic S3 heart sound
Marker of ventricular overload and/or systolic dysfunction
Low pitch, best heard with bell, might miss with diaphragm
S1 S2 S3 For diagnosis of heart failure, correlate with additional findings such as dyspnea, tachycardia, crackles. Finding can resolve with treatment of underlying condition
Systolic Murmurs •Mitral •Regurgitation •Physiologic (innocent, functional) •Aortic •Stenosis •Systolic
can be benign or pathologic
DIalstolic murmurs are:
always pathologic
Systolic murmur is likely benign:
• Consider benign only if all noted– Negative hx– Lower grade (<=Gr III/VI)– No radiation beyond the precordium– S1, S2 intact– No heave or thrill– PMI WNL– Softens or disappears with supine to stand position change
Pathologic • Consider pathologic (echocardiogram usual next step in evaluation) until proven otherwise if
=>1 of the following present–
Abnormal hx–
Higher grade (=>Gr IV/VI)– Radiation beyond the precordium to neck, axilla, other locations–
S1, S2 obliterated– w/ thrill or heave–
PMI displaced–
Increases in intensity with supine to stand position change
