A nurse is planning care for a client following a cardiac catheterization accessed through his femoral artery. Which of the following actions should the nurse plan to take?

The nurse should explain that cardiac enzyme studies measure the levels of certain enzymes, such as troponin, creatine kinase, and lactate dehydrogenase, that are released into the bloodstream when the heart muscle is damaged by an MI. These tests help determine the degree of damage to the heart tissues, as well as the timing and severity of the MI.

"These tests will enable the provider to determine the heart structure and mobility of the heart valves." is wrong because cardiac enzyme studies do not provide information about the heart structure and mobility of the heart valves. Other tests, such as echocardiography or cardiac catheterization, may be used for this purpose.

"Cardiac enzymes will identify the location of the MI." is wrong because cardiac enzyme studies do not indicate the specific location of the MI within the heart. Other tests, such as electrocardiography or coronary angiography, may be used for this purpose.

"Cardiac enzymes assist in diagnosing the presence of pulmonary congestion." is wrong because cardiac enzyme studies do not directly assess the presence of pulmonary congestion, which is a complication of heart failure. Other signs and symptoms, such as dyspnea, crackles, and chest x-ray findings, may be used for this purpose.

Performing neurovascular checks with vital signs is an important action to take following a cardiac catheterization accessed through the femoral artery, as it can help monitor for complications such as bleeding, hematoma, infection, thrombosis, or embolism. The nurse should assess the color, temperature, sensation, movement, and pulses of the affected leg, as well as the blood pressure, heart rate, and oxygen saturation of the client.

Instructing the client to perform range-of-motion exercises to his lower extremities is not appropriate, as it can increase the risk of bleeding or dislodging the arterial sheath or closure device. The client should keep the affected leg straight and avoid bending or lifting it for several hours after the procedure, or as directed by the provider.

Restricting the client's fluid intake is not necessary, as fluid intake can help prevent dehydration and contrast- induced nephropathy following a cardiac catheterization. The client should be encouraged to drink fluids, unless contraindicated.

dAmbulating the client 1 hr following the procedure is not advisable, as it can cause bleeding, hematoma, or vascular injury. The client should remain on bed rest for 2 to 6 hours after the procedure, or as directed by the provider, and resume ambulation gradually and with assistance.
