The nurse teaches a student nurse about diagnostic studies used for acute coronary syndrome. Which statement made by the student nurse indicates effective learning?
"A nitroprusside stress echocardiogram is used for patients with acute pericarditis."
"A pathologic Q wave is always present in the electrocardiogram (ECG) of patients with unstable angina."
"Serum cardiac markers are proteins that are released from necrotic heart muscle."
"Coronary angiography is the only way to confirm the diagnosis of unstable angina."
The Correct Answer is C
This statement indicates effective learning because serum cardiac markers are indeed proteins that are released from necrotic (damaged) heart muscle cells when there is myocardial injury, such as in acute coronary syndrome (ACS). These markers are measured in blood tests and help in the diagnosis and assessment of ACS, particularly myocardial infarction (heart attack).
Option A is incorrect because a nitroprusside stress echocardiogram is not used for acute pericarditis. It is a diagnostic test used for evaluating coronary artery disease and ischemia.
Option B is incorrect because a pathologic Q wave is not always present in the electrocardiogram (ECG) of patients with unstable angina. It is a characteristic finding in the ECG of patients with a previous myocardial infarction (heart attack) but may not be present in unstable angina.
Option D is incorrect because coronary angiography is not the only way to confirm the diagnosis of unstable angina. Unstable angina is primarily diagnosed based on the clinical presentation, symptoms, and changes in the ECG. Coronary angiography is an invasive procedure used to visualize the coronary arteries directly and is typically reserved for cases where further assessment and intervention are needed, such as in cases of suspected coronary artery disease.

Correct Answer is B
Explanation
Resumption of sexual activity after a myocardial infarction (MI) is an important topic to address as part of the overall recovery and rehabilitation process. It should be discussed along with other physical activities during the patient's recovery. The nurse should initiate the discussion in a supportive and non-judgmental manner, addressing the patient's concerns, fears, and questions about sexual activity after an MI.
Sexual activity is a normal part of life, and patients may have concerns about the safety and appropriateness of engaging in sexual activity after a significant cardiac event like an MI. Discussing it along with other physical activities helps normalize the topic and allows the nurse to provide accurate information, address any misconceptions, and offer guidance on when and how to resume sexual activity safely. Patients should be encouraged to have an open dialogue with their healthcare provider about their concerns and any specific questions they may have related to resuming sexual activity.
Correct Answer is C
Explanation
The client's presentation of chest pain radiating to the left arm, sweating, shortness of breath, epigastric discomfort, cool and diaphoretic skin, tachycardia, and ST elevation on the electrocardiogram (ECG) are indicative of myocardial infarction (heart attack). These symptoms and findings are typical of acute coronary syndrome, specifically an ST-segment elevation myocardial infarction (STEMI).
Option A (Ischemic Stroke) is not the correct answer because the symptoms described in the client's presentation are primarily related to the cardiovascular system and not indicative of an ischemic stroke.
Option B (Chronic Stable Angina) is not the correct answer because chronic stable angina typically presents with chest pain on exertion or stress, and it usually subsides with rest or nitroglycerin. The client's symptoms of chest pain at rest, along with other findings, are more concerning for an acute cardiac event like a myocardial infarction.
Option D (Cardiogenic Shock) is a severe complication that can occur following a myocardial infarction, but the information provided in the scenario does not suggest that the client is in cardiogenic shock at this time. The client's blood pressure is not mentioned in the scenario, which is a crucial parameter to assess for cardiogenic shock.
