A nurse is providing education to a client who has asked what a transesophageal echocardiogram will determine. Which of the following statements should the nurse utilize to best answer the client?

This procedure will detect ventricular thrombi.

This procedure will determine heart conduction problems.

This procedure will determine exercise tolerance.

This procedure will detect blood flow to the distal extremities.

Answer and Explanation

The Correct Answer is A

Rationale:

A. A transesophageal echocardiogram (TEE) is a specialized echocardiographic procedure that provides detailed images of the heart, including the atria and ventricles. It is particularly useful for detecting ventricular thrombi (blood clots) that may not be visualized as well with transthoracic echocardiography.

B. While an echocardiogram can provide information about heart function, including conduction problems, a TEE is not typically used specifically for this purpose.

C. Exercise tolerance is typically assessed through exercise stress testing or other exercise- related procedures, not with a TEE.

D. Blood flow to the distal extremities is not directly assessed with a TEE. This procedure primarily focuses on evaluating cardiac structure and function.

Correct Answer is B

Explanation

Rationale:

A. Partial thromboplastin time (PTT) is used to monitor the effectiveness of heparin therapy, not warfarin.

B. Prothrombin time (PT) and international normalized ratio (INR) are used to monitor the therapeutic level of warfarin. INR is the preferred method as it standardizes the PT results across different laboratories.

C. D-dimer level is a marker of fibrin degradation and is used to assess for the presence of blood clots, not to monitor warfarin therapy.

D. Vitamin K level is not used to monitor warfarin therapy. However, administering vitamin K can reverse the effects of warfarin in cases of overdose or hemorrhage.

A. This medication will cause a dry cough. B. This medication will cause drowsiness. C. This medication will lower my heart rate. D. This medication will lower my LDL.

Correct Answer is A

Explanation

Rationale:

A. Captopril, an angiotensin-converting enzyme (ACE) inhibitor, commonly causes a dry cough as a side effect due to the accumulation of bradykinin.

B. Captopril typically does not cause drowsiness as a side effect.

C. Captopril may cause a decrease in heart rate as a result of its vasodilatory effects, but this is not a primary therapeutic effect of the medication.

D. Captopril primarily affects blood pressure and heart function but does not directly lower LDL cholesterol levels.
