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?

Impaired tissue perfusion is a nursing diagnosis that indicates a decrease in oxygen and nutrient delivery to the tissues, resulting in cellular dysfunction and potential tissue damage or necrosis. It is the priority nursing diagnosis for a client who has varicose veins with ulcerations and lower extremity edema, as these are signs of chronic venous insufficiency, which is a condition in which the veins in the legs fail to return blood to the heart effectively, causing blood to pool and stagnate in the lower extremities. This leads to increased venous pressure, inflammation, and impaired wound healing, which can cause skin breakdown, infection, and tissue necrosis. The nurse should monitor the client's vital signs, peripheral pulses, capillary refill, skin color, temperature, and sensation, and implement interventions to improve venous return and prevent further complications, such as elevating the legs, applying compression stockings, encouraging ambulation, administering medications, and providing wound care.

Alteration in body image. This is a nursing diagnosis that indicates a negative perception or dissatisfaction with one's physical appearance or function. It may be applicable for a client who has varicose veins with ulcerations and lower extremity edema, as these may affect their self-esteem and social interactions. However, it is not the priority nursing diagnosis for this client, as it does not pose an immediate threat to their health or safety.

Alteration in activity tolerance. This is a nursing diagnosis that indicates a decrease in the ability to perform physical activities without experiencing fatigue, dyspnea, or other symptoms. It may be applicable for a client who has varicose veins with ulcerations and lower extremity edema, as these may limit their mobility and endurance. However, it is not the priority nursing diagnosis for this client, as it does not pose an immediate threat to their health or safety.

Impaired skin integrity. This is a nursing diagnosis that indicates a disruption or damage to the epidermis or dermis layers of the skin. It is applicable for a client who has varicose veins with ulcerations and lower extremity edema, as these can cause skin breakdown and infection. However, it is not the priority nursing diagnosis for this client, as it is a consequence of impaired tissue perfusion, which is the underlying problem that needs to be addressed first.

An exercise stress test is a diagnostic procedure that measures the heart's response to physical activity. The client is instructed to walk on a treadmill or pedal a stationary bike while their heart rate, blood pressure, and electrocardiogram are monitored. The test can help detect coronary artery disease, arrhythmias, or other cardiac problems.

The client should follow certain guidelines before the test, such as:

• Avoiding caffeine, nicotine, alcohol, and stimulants for at least 4 hours before the test, as they can affect the heart rate and blood pressure.
• Fasting for at least 2 hours before the test, as eating can affect the blood flow to the heart.
• Getting adequate rest and sleep the night before the test, as fatigue can affect the performance and results of the test.
• Wearing comfortable clothing and shoes that are suitable for exercise.
• Informing the provider of any medications they are taking, as some medications may need to be withheld or adjusted before the test, such as beta blockers, calcium channel blockers, nitrates, or antiarrhythmics. These medications can affect the heart rate and blood pressure and interfere with the interpretation of the test results.

Therefore, the comment made by the client that indicates a need for further teaching is "I'll take my heart medications the morning of my test." The client should consult with their provider about whether they should take their heart medications or not before the test. The other comments made by the client are appropriate and indicate that they understand the pre-test instructions.
