What is the nurses response when Mr Griffin asks what is the biggest worry about having atrial fibrillation?

-Heart rate is between 60 and 100 beats/min (bpm)
-The T wave is rounded and smooth -A P wave is visible before each QRS complex

Rationale:
Normal results for an ECG include a heart rate between 60 and 100 beats/min, normal sinus rhythm, a P wave that precedes each QRS complex, a PR interval that lasts 0.12 to 0.20 seconds, a QRS complex that lasts 0.12 seconds, an ST segment less than or equal to 0.1 mV, a T wave that is rounded, smooth, and is positive in leads I, II, V3, V4, V5, and V6. Finally, the QT interval duration varies but usually lasts 0.36 to 0.44 seconds.

Thin, shiny skin over calves, Absence of hair over the lower legs

Rationale:
Cold, pale, clammy skin on the extremities and thin, shiny skin with loss of hair, especially over the lower legs, are associated with arterial insufficiency. Warm skin and brown pigmentation around the ankles are associated with venous insufficiency. Intermittent claudication is characterized by weakness, cramping, aching, fatigue, or frank pain located in the calves, thighs, or buttocks—but rarely in the feet with activity. These symptoms are quickly relieved by rest. Ulcers associated with arterial disease are usually painful and are often located on the toes, foot, or lateral ankle. Venous ulcers are usually painless and occur on the lower leg or medial ankle.

Assess heart rate and rhythm using the diaphragm of the stethoscope, Ask the patient to lie on the left side to assess sounds from the apex of the heart, Assess the apex, left sternal border, and base of the heart for abnormal pulsations, Auscultate over the aortic, pulmonic, tricuspid, and mitral areas, as well as Erb's point
Rationale:
Effective technique for the assessment of the heart would include assessing the apex, left sternal border, and base of the heart for abnormal pulsations; auscultating over the aortic, pulmonic, tricuspid, and mitral areas, as well Erb's point; assessing sounds from the apex of the heart while the patient is positioned on the left side; and using the diaphragm of the stethoscope to assess the heart's rate and rhythm. Assessing S1 and S2 heart sounds is done using the diaphragm of the stethoscope, not the bell.
