                               An abnormal pulsation that can be seen on inspection of the neck is jugular
                            venous distention (JVD). With the patient lying supine and the head elevated
                            30 to 45 degrees, you should not see visible pulsation at the side of the neck.
                            JVD is a response to increased intrathoracic pressure during the Valsalva
                            maneuver and can temporarily be seen normally when a weightlifter bears
                            down while lifting weights. If you see visible pulsations that occur above the
                            jaw line, this might indicate an increase in circulating volume to the right side
                            of the heart, which can be caused by right-sided heart failure.



                              NURSING ALERT

                              Inspect the jugular veins for pulsations and distention, which might be apparent and
                              indicative of right-sided cardiac failure.



                               Inspection of the valvular areas requires that the nurse know where these
                            valves are located. Once the nurse knows where these are, she or he can use the
                            same areas on auscultation of these valves (see Table 3–3).                         Downloaded by [ Faculty of Nursing, Chiangmai University 5.62.158.117] at [07/18/16].

                             Aortic      2nd ICS (intercostal space) to right of sternum. Only region heart
                                         sounds heard to right of sternum.
                             Pulmonic    2nd ICS, to the left of the sternum. Right across from the aortic
                                         area.
                             Tricuspid   4th ICS to the left of the sternum, 4th intercostal space
                             Mitral      5th ICS, MCL (midclavicular line); PMI



                               The PMI may be seen in thin-chest-walled patients and is normal to see. All
                            other pulsations in the chest are considered abnormal and might be due to
                            valvular changes in the heart or heart enlargement (cardiomegaly).


                            Palpation
                            This assessment skill is best achieved by the nurse using a light sense of touch and
                            a relaxed, unhurried approach. Palpation is used to assess pulsations in the neck,
                            thorax, abdomen, and extremities. It is also used to assess skin turgor, capillary
