The nurse is assessing a patient who takes warfarin (Coumadin). The nurse notes a heart rate of 92 beats per minute and a blood pressure of 88/78 mm Hg. To evaluate the reason for these vital signs, the nurse will assess the patient's
a. gums, nose, and skin.
b. lung sounds and respiratory effort.
c. skin turgor and oral mucous membranes.
d. urine output and level of consciousness.
ANS: A
An increased heart rate followed by a decreased systolic pressure can indicate a fluid volume deficit caused by internal or external bleeding. The nurse should examine the patient's mouth, nose, and skin for bleeding. These vital signs do not indicate a pulmonary problem. Skin turgor and mucous membranes as well as urine output and level of consciousness may be assessed to determine the level of fluid deficit, but finding the source of blood loss is more important. Signs of gastrointestinal bleeding should also be assessed.
