A nurse accompanies a client to an exercise stress test. The client can achieve the target heart rate, but the electrocardiogram indicates ST-segment elevation. Which procedure will the nurse prepare the patient for?
cardiac catheterization
transesophageal echocardiogram
telemetry monitoring
pharmacologic stress test
The Correct Answer is A
ST-segment elevation during exercise stress testing is a concerning finding that may indicate reduced blood flow to the heart muscle. It can be a sign of myocardial ischemia or coronary artery disease. Cardiac catheterization is a diagnostic procedure that allows direct visualization of the coronary arteries and helps identify any blockages or narrowing that may be causing the ST-segment elevation.
Here's an explanation of why the other options are not the most appropriate procedures:
Transesophageal echocardiogram: Transesophageal echocardiogram (TEE) is a diagnostic test that involves inserting a probe into the esophagus to obtain detailed images of the heart. It is not typically used to evaluate ST-segment elevation, which primarily indicates coronary artery issues rather than structural abnormalities.
Telemetry monitoring: Telemetry monitoring involves continuous monitoring of a patient's heart rhythm and can be used for various cardiac conditions. While telemetry monitoring may be necessary for ongoing cardiac assessment, it is not a specific procedure to address the ST-segment elevation found during the exercise stress test.
Pharmacologic stress test: A pharmacologic stress test is an alternative to an exercise stress test for patients who cannot exercise. It involves administering medications that stimulate the heart to mimic the effects of exercise. While a pharmacologic stress test can also reveal ST-segment changes, the presence of ST-segment elevation usually requires further evaluation with a more invasive procedure like cardiac catheterization.

The importance of ensuring the stockings are applied evenly with no pressure points: Compression stockings are designed to provide graduated pressure to the legs, helping improve blood flow and reduce swelling in individuals with venous insufficiency. It is crucial for the client to understand how to properly apply the stockings to maximize their effectiveness and prevent any complications. The nurse should emphasize the following points:
● Ensure the stockings are applied evenly: The stockings should be applied smoothly and evenly without any folds or wrinkles. This helps ensure that the pressure is distributed uniformly, enhancing their therapeutic effect.
● Check for pressure points: The client should be instructed to pay attention to any areas where the stockings may be causing excessive pressure or discomfort. Pressure points can impair circulation or cause skin damage. If pressure points are noticed, adjustments should be made to ensure proper fit and comfort.
● Follow manufacturer's instructions: The nurse should provide specific instructions regarding how to correctly don the compression stockings, including any specific guidelines provided by the manufacturer. This may include recommendations for the time of day to apply the stockings or any specific donning techniques.
The other options mentioned in the question are not essential information for the teaching plan:
The need to take anticoagulants concurrent with using compression stockings: While some individuals with venous insufficiency may require anticoagulant therapy, it is not directly related to the use of compression stockings. Anticoagulant therapy is typically prescribed for other reasons, such as prevention or treatment of blood clots.
The need to wear the stockings on a one day on, one day off schedule: Wearing compression stockings on a specific schedule of one day on, one day off is not a standard recommendation. The frequency and duration of wearing compression stockings may vary based on individual needs and healthcare provider's recommendations.
The importance of wearing the stockings around the clock to ensure maximum benefit: While consistent and regular use of compression stockings is important, it is not necessary to wear them around the clock. Healthcare providers typically provide specific guidelines on how long the stockings should be worn each day, which may vary based on the severity of venous insufficiency and individual factors.
Correct Answer is C
Explanation
The client statement that supports the information of intermittent claudication is: "My legs get a painful cramp when I walk over 30 minutes.": Intermittent claudication is a symptom of peripheral artery disease (PAD) characterized by pain, cramping, or fatigue in the muscles of the lower extremities, typically the calves, thighs, or buttocks. This pain is usually triggered by physical activity, such as walking, and is relieved with rest. The pain is caused by inadequate blood flow and oxygen supply to the muscles due to narrowed or blocked arteries.
The other client statements do not specifically indicate intermittent claudication:
"My feet feel like I have pins and needles": This sensation of pins and needles is often associated with peripheral neuropathy, which is a condition involving nerve damage and does not directly relate to intermittent claudication.
"When I stand or sit too long, my feet swell": This statement suggests the possibility of venous insufficiency rather than intermittent claudication. Venous insufficiency involves impaired blood return from the legs to the heart and may result in swelling, aching, or heaviness in the legs.
"I get short of breath when I climb a lot of stairs": This symptom is more indicative of cardiovascular or respiratory issues, such as heart or lung disease, rather than intermittent claudication. It suggests that the client may experience exercise intolerance due to cardiopulmonary limitations.
