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.

Correct Answer is A
Explanation
Elevated levels of LDL (low-density lipoprotein) cholesterol are associated with an increased risk of coronary artery disease (CAD). LDL cholesterol is often referred to as "bad" cholesterol because it can contribute to the formation of plaque in the arteries, leading to narrowing and blockage of the arteries supplying the heart. This increases the risk of developing CAD and related complications such as heart attack and stroke.
On the other hand, HDL (high-density lipoprotein) cholesterol is often referred to as "good" cholesterol. HDL cholesterol helps remove excess cholesterol from the bloodstream and transport it back to the liver for processing and excretion. Higher levels of HDL cholesterol are associated with a decreased risk of CAD because it helps to prevent the accumulation of cholesterol on artery walls.
Therefore, understanding that increased LDL and decreased HDL levels increase the risk of coronary artery disease demonstrates a good understanding of the significance of cholesterol levels and their impact on cardiovascular health.
Correct Answer is A
Explanation
Hypertension is typically diagnosed when a person's blood pressure consistently exceeds 130/80 mm Hg on multiple occasions. However, the specific target blood pressure for treatment may vary based on individual factors and the presence of other comorbidities.
Among the options provided, a blood pressure reading of 128/76 mm Hg is within the target range for many individuals with hypertension. The systolic pressure (128 mm Hg) is below the threshold of 130 mm Hg, and the diastolic pressure (76 mm Hg) is below the threshold of 80 mm Hg.
The other blood pressure readings would warrant further evaluation or possible changes in therapy:
128/92 mm Hg: The diastolic pressure (92 mm Hg) is above the threshold of 80 mm Hg, indicating uncontrolled hypertension.
98/56 mm Hg: This blood pressure reading is below the threshold for hypertension, but it is considered low and may require further assessment to determine if it is normal for the individual or if it indicates hypotension.
142/78 mm Hg: While the systolic pressure (142 mm Hg) is slightly above the threshold of 130 mm Hg, it may not necessarily require immediate changes in therapy. However, it should be closely monitored to ensure blood pressure control.
