NCLEX-PN® ExaminationReduction of Risk PotentialMedium

A client with a history of heart failure is scheduled for a transthoracic echocardiogram (TTE). The client asks the LPN, 'What should I expect during this test?' Which response by the LPN is most appropriate?

  1. A'This test involves placing a long, thin tube down your throat to get a clear view of your heart chambers.'
  2. B'You will be asked to walk on a treadmill, and then pictures of your heart will be taken before and after exercise.'
  3. C'You will need to lie still on your back for about 30 minutes while a small probe is moved over your chest.'
  4. D'A special dye will be injected into your vein, and then X-ray pictures of your heart will be taken.'
Show answer & explanation

Correct answer: C. 'You will need to lie still on your back for about 30 minutes while a small probe is moved over your chest.'

A transthoracic echocardiogram (TTE) is a non-invasive procedure where a transducer (probe) is moved over the chest to obtain ultrasound images of the heart. The client lies still, usually on their left side, during the 30-60 minute procedure.

Why the other options are wrong

  • A. This describes a transesophageal echocardiogram (TEE), which is an invasive procedure.
  • B. This describes a stress echocardiogram, which is a type of TTE but not the general TTE procedure itself.
  • D. This describes a cardiac catheterization or angiogram, not a TTE.

Transthoracic Echocardiogram (TTE)

A non-invasive ultrasound test that uses sound waves to create live images of your heart, showing its size, structure, and how well it's pumping blood.

  • Non-invasive, uses a transducer on the chest.
  • Client lies still, usually on left side.
  • Takes 30-60 minutes; no special prep needed.

Memory trick: Echo: 'Echo' (sound waves), 'Chest' (TTE), 'Throat' (TEE), 'Run' (Stress).
