The client is having an exercise echocardiogram. What is a nursing instruction for this test?

Correct Answer: B

Rationale: The correct answer is B because during an exercise echocardiogram, the client typically exercises on a treadmill to stress the heart. This helps evaluate how the heart functions under physical exertion. After exercising, the client immediately undergoes an echocardiogram to assess the heart's response to stress. This test provides valuable information about heart function during activity. Choice A is incorrect because lying on the back is not part of the standard procedure for an exercise echocardiogram. Choice C is incorrect as lying on the right side is not a common position for this test. Choice D is incorrect because electrocardiographic monitoring is essential during an exercise echocardiogram to assess the heart's electrical activity throughout the test.

Correct Answer: B

Rationale: The correct answer is B. This statement indicates a misunderstanding about the procedure for CABG surgery using the internal mammary artery. The internal mammary artery is typically used for the bypass graft, not a vein from the leg. The other choices (A, C, D) are all accurate statements related to CABG surgery. Choice A correctly describes the use of a heart-lung machine during surgery. Choice C accurately explains the purpose of using an artery near the heart for the bypass. Choice D is true as aspirin is often prescribed post-surgery to prevent graft occlusion. Therefore, B is the incorrect choice as it does not align with the procedure being discussed.

Correct Answer: A

Rationale: The correct answer is A: Attach the heart monitor. This should be done first to continuously monitor the patient's cardiac rhythm and detect any potential arrhythmias or changes in heart rate. This is crucial in managing NSTEMI patients. Obtaining blood pressure, assessing peripheral pulses, and auscultating breath sounds are important assessments, but monitoring the heart rhythm takes precedence in NSTEMI to identify any cardiac complications promptly.

Correct Answer: B

Rationale: Certainly! The correct answer is B: Assess the client. Ventricular tachycardia may or may not require immediate intervention like defibrillation. Assessing the client's condition first allows the nurse to gather vital information such as the client's level of consciousness, vital signs, and overall stability. This assessment will guide the nurse in determining the appropriate next steps, which may include interventions like defibrillation, calling the physician, or administering treatment. Performing immediate defibrillation (choice A) without assessing the client's condition can be harmful if the client does not actually require it. Calling the physician (choice C) can be done after assessing the client to provide a comprehensive report. Administering a precordial thump (choice D) is not recommended in current guidelines and should not be the initial response to ventricular tachycardia.

Correct Answer: A

Rationale: The correct answer is A because in a client presenting with substernal chest pain, electrocardiographic changes, and elevated cardiac troponin level, the priority is to improve myocardial oxygenation and reduce cardiac workload. This is crucial to prevent further damage to the heart muscle and potential complications like myocardial infarction. By focusing on improving oxygen supply and reducing workload, the nurse can help stabilize the client's condition and prevent further cardiac events. Choice B is incorrect because while confirming the diagnosis and preventing complications are essential, the immediate focus should be on addressing the physiological needs of the heart. Choice C is incorrect as reducing anxiety and relieving pain are important but secondary to addressing the underlying cardiac issue. Choice D is incorrect as eliminating stressors and providing a nondemanding environment may be beneficial but not the immediate priority in this situation.
