A client is scheduled for a transthoracic echocardiography (TTE). What should the nurse teach the client in anticipation of this diagnostic procedure?

The test is noninvasive, and nothing will be inserted into the client's body.

The client will remain on bed rest for 1 to 2 hours after the test.

The client's pain will be managed aggressively during the procedure.

The test will provide a detailed profile of the heart's electrical activity.

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is D

Explanation

A. Sinus bradycardia: Sinus bradycardia is characterized by a regular rhythm with a heart rate less than 60 beats per minute. In this case, the heart rate is 64 beats per minute, which falls within the normal range, not consistent with sinus bradycardia.

B. Sinus arrhythmia: Sinus arrhythmia typically presents as a variation in the R-R interval with respiration, often seen as an irregularity in the heart rate. The provided characteristics describe a regular rhythm, so sinus arrhythmia is not the correct interpretation.

C. Sinus tachycardia: Sinus tachycardia is characterized by a regular rhythm with a heart rate greater than 100 beats per minute. The heart rate in this case is 64 beats per minute, which is not indicative of sinus tachycardia.

D. Normal sinus rhythm: Normal sinus rhythm refers to a regular rhythm with a heart rate between 60 and 100 beats per minute, P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and normal QRS complex duration (less than 0.12 seconds). The provided characteristics, including regular P waves, regular QRS complexes, a PR interval of 0.16 seconds, and a heart rate of 64 beats per minute, align with a normal sinus rhythm interpretation.

A. Furosemide 10mg IV bolus every 12 hours. B. Morphine sulfate 2 mg IV bolus every 2 hr PRN pain C. Laboratory testing of serum potassium upon admission D. 0.9% normal saline IV at 150 mL/hr continuous

Correct Answer is D

Explanation

A. Furosemide 10mg IV bolus every 12 hours:

Furosemide is a loop diuretic commonly used in heart failure management to reduce fluid overload. The prescribed dose of 10 mg IV bolus every 12 hours is within the typical range for furosemide administration in acute heart failure.

B. Morphine sulfate 2 mg IV bolus every 2 hr PRN pain:

Morphine sulfate is often used in the management of acute pain, including pain associated with myocardial infarction. The prescribed dose of 2 mg IV bolus every 2 hours PRN for pain is appropriate and aligns with standard pain management protocols.

C. Laboratory testing of serum potassium upon admission:

It is common practice to perform laboratory testing, including serum potassium levels, upon admission for clients with acute heart failure, especially if they are receiving diuretics or other medications that can affect electrolyte balance. This prescription is appropriate and necessary for monitoring the client's condition.

D. 0.9% normal saline IV at 150 mL/hr continuous:

This prescription raises a concern because administering 0.9% normal saline at a rate of 150 mL/hr continuously may lead to fluid overload in a client with acute heart failure. The rate of IV fluid administration should be carefully assessed based on the client's fluid status, renal function, and hemodynamic parameters to avoid exacerbating heart failure symptoms.
