Suspicious breast mass -A mobile mass that becomes fixed when the arm relaxes is attached to the ribs and intercostal muscles; if fixed when the hand is pressed against the hip, it is attached to the pectoral fascia. -Hard irregular poorly circumscribed nodules, fixed to the skin or underlying tissues, strongly suggest cancer Risk for Breast cancer --Age -family history of breast/ovarian CA - inherited genetic mutations, -personal history of breast cancer - high levels of endogenous ho...

1. Myocardial infarction, valvular problems, neurological influences: What medical conditions place pressure on the atria, causing atrial dysrhythmias to occur? 2. the waveform has an equally positive and negative deflection on the ECG tracing: In a premature atrial complex (PAC), the P wave may be biphasic. This means: 3. Premature Atrial Complexes (PAC): Which atrial dysrhythmia has a cardiac complex that occurs too soon, has a positively deflected P wave, and other than being early, has no ...

Basic Arrhythmias Exam Questions with Complete Answers Latest Update What is the primary pacemaker site of the heart and its intrinsic rate - Answers SA node 60-100 What are the two escape pacemaker sites and their intrinsic rates - Answers AV 40-60 and ventricle 20-40 What is the primary function of the AV node and why is it important - Answers It catches and delays the impulse, so the ventricles can fill=atrial kick What value of time is associated with a small box - Answers .04 What val...

sinus node - ANSWER The intrinsic pacemaker. Cell membrane "leakiness" causes spontaneous depolarization at a rate of 60-100 times a minute. AV node - ANSWER Acts like a resistor to slow the impulse allowing time for the atria to completely contract before initiating ventricular contraction. Back up pacemaker if SA fails, pacing at a rate of 40-60 times a minute. Bundle of his - ANSWER "Cable" that passes through the fibrous sheath separating atria from ventricles. Divides into the bun...
