^Ch. 29 Thorax Heart Abdomen Flashcards
Midsternal line
is through the center of the sternum
midclavicular line
is through the midpoint of the clavicle
anterior axillary line
is through the anterior axillary folds
midaxillary line
is through the apex of axillae
posterior axillary line
is through the posterior axillary fold
the right and left scapular lines
are through the inferior angle of scapula
vertebral line
is along the center of the spine
Dysrhythmia
occurs when the heart fails to beat at a regular successive interval
Gallops
are extra heart sounds.
ventricular gallops
occurs after S2 sounds like Ken-tuck-y
Arterial gallop
occurs before S1 sounds Ten-es-see
Murmurs
are audible when blood volume in heart increased or its flow is impeded or altered
systolic murmurs
occur just after S1
Diastolic murmur
occur just after S2
percussion
compare sounds from side to side
-percussion of the thorax elicits resonance
unexpected finding percussion
dullness- fluid or solid tissues, this can indicate pneumonia or a tumor
-hyper-resonance: in the presence of air, this can indicate pneumothorax or emphysema
Auscultation Bronchial sounds
loud, high pitched, hollow quality, expiration longer than inspiration over the trachea
Auscultation Broncho vesicular
medium pitch, blowing sounds and intensity with equal inspiration and expiration times over the larger airways
Auscultation vesicular
soft, low pitched breezy sounds inspiration three times longer than expiration over most of the peripheral areas of the lungs
Crackles or rales
fine to coarse bubbly sounds (not clear with coughing) as air passes through fluid or re-expands collapsed small airways
