A patient admitted to the unit displays the following cardiac rhythm on telemetry. What is the estimated heart rate?

A. The test is noninvasive, and nothing will be inserted into the client's body: Transthoracic echocardiography (TTE) is a noninvasive procedure that uses ultrasound waves to create images of the heart. It involves placing a transducer on the chest wall to capture images of the heart's structure and function. The nurse should inform the client that no instruments or devices will be inserted into their body during the test.

B. The client will remain on bed rest for 1 to 2 hours after the test: This statement is not typically accurate for a TTE procedure. After a TTE, clients can usually resume their normal activities without any specific bed rest requirements, unless otherwise specified by the healthcare provider based on individual circumstances.

C. The client's pain will be managed aggressively during the procedure: TTE is generally a painless procedure that does not require aggressive pain management. The client may feel slight discomfort from the transducer's pressure on the chest, but it is typically well tolerated without the need for pain medication.

D. The test will provide a detailed profile of the heart's electrical activity: While echocardiography provides detailed images of the heart's structure and function, including information about blood flow and valve function, it does not directly assess the heart's electrical activity. For evaluating electrical activity, other tests such as electrocardiography (ECG or EKG) would be used.

A. The pain can be severe and sudden at rest: This statement is more characteristic of unstable angina, where chest pain can occur at rest or with minimal exertion and is often severe and unpredictable.

B. The pain persists with rest and organic nitrates: This statement is more indicative of unstable angina or variant (Prinzmetal's) angina. Stable angina typically improves with rest and nitroglycerin (an organic nitrate).

C. The pain usually lasts longer than 20 minutes: Stable angina pain typically lasts for a few minutes (usually less than 5 to 10 minutes) and resolves with rest or nitroglycerin. Pain lasting longer than 20 minutes may indicate an acute coronary syndrome such as unstable angina or myocardial infarction.

D. Exertion and anxiety can trigger the pain: This statement is accurate for stable angina. Exertion, such as physical activity or emotional stress, can trigger anginal pain in individuals with stable angina due to increased oxygen demand by the heart.
