During a stress test on a treadmill, which observation by the nurse would necessitate immediate action?
Sinus tachycardia at a rate of 110 beats/min.
Blood pressure increase from 134/68 to 150/80 mm Hg.
The patient reports feeling tired.
Inversion of T waves on the electrocardiogram.
The Correct Answer is D
Choice A rationale
Sinus tachycardia at a rate of 110 beats/min is a normal response to exercise. During a stress test, the heart rate will naturally increase as the body’s demand for oxygen increases. A heart rate of 110 beats/min is within the expected range during moderate exercise.
Choice B rationale
An increase in blood pressure from 134/68 to 150/80 mm Hg is a normal response to exercise. During a stress test, blood pressure will naturally rise as the heart works harder to pump blood to the muscles. This increase is within the expected range during moderate exercise.
Choice C rationale
Feeling tired during a stress test on a treadmill is a normal response to exercise. Fatigue can occur as the body’s energy stores are used up during physical activity. However, if the patient reports extreme fatigue or other symptoms such as chest pain or shortness of breath, it may indicate a problem.
Choice D rationale
Inversion of T waves on the electrocardiogram during a stress test is a sign of myocardial ischemia, a condition in which the heart muscle is not getting enough oxygen. This could indicate the presence of significant coronary artery disease and is a finding that would necessitate immediate action.

Correct Answer is C
Explanation
Choice A rationale
While assessing the gag reflex is important in certain situations, such as after surgery involving anesthesia, it is not typically a crucial assessment following Percutaneous Transluminal Angioplasty (PTA) of the lower extremity.
Choice B rationale
Checking for dye allergies is important before a procedure that uses contrast dye. However, it is not a crucial post-procedure assessment.
Choice C rationale
Monitoring of pedal pulses is crucial following PTA of the lower extremity. This is because the procedure involves the arteries in the legs, and monitoring pedal pulses can help assess blood flow to the area and detect potential complications such as occlusion or clot formation.
Choice D rationale
While the Ankle-Brachial Index can be used to diagnose Peripheral Arterial Disease (PAD), it is not typically a crucial assessment immediately following PTA3.
Correct Answer is ["A","B","D","E"]
Explanation
Choice A rationale
Weight loss is often recommended as a first-line therapeutic approach to lowering blood pressure in patients diagnosed with essential hypertension. Excess weight can increase the strain on the heart and blood vessels, leading to higher blood pressure.
Choice B rationale
Regular physical activity is another important part of managing hypertension. Exercise can help lower blood pressure by improving heart health and reducing weight.
Choice C rationale
Beta-blockers, such as propranolol, are a type of medication used to treat hypertension. However, they are not typically the first choice for initial therapy unless the patient has a specific indication for this class of medication, such as heart failure or angina.
Choice D rationale
Decreasing sodium intake is another lifestyle change that can help lower blood pressure. Consuming too much sodium can cause the body to retain fluid, which can increase blood pressure.
Choice E rationale
Smoking cessation is also recommended for patients with hypertension. While smoking does not directly cause high blood pressure, it can damage blood vessels and increase the risk of heart disease.
