A nurse is performing an electrocardiogram (ECG) on a client who is experiencing chest pain. Which of the following statements should the nurse make?

The test will be complete in 30 to 60 minutes.

You may feel a slight tingling while the test is being done.

The radioactivity from the dye lasts only a few hours.

I will need to apply electrodes to your chest and extremities.

Answer and Explanation

The Correct Answer is D

Choice A reason : The statement that the test will be complete in 30 to 60 minutes is incorrect. An ECG is a quick, non-invasive procedure that typically takes only a few minutes to perform.

Choice B reason : The statement about feeling a slight tingling is not accurate for an ECG. This test does not cause any sensations, as it simply records the electrical activity of the heart.

Choice C reason : The mention of radioactivity from dye is not applicable to an ECG. This test does not involve the use of any dyes or radioactive substances. Dyes are typically used in imaging tests like CT scans or MRIs, not ECGs.

Choice D reason : This is the correct statement. For an ECG, electrodes are placed on the patient's chest and extremities to record the electrical activity of the heart. This allows the healthcare provider to assess the heart's rhythm, identify any irregularities, and diagnose conditions.

Correct Answer is ["50"]

Explanation

Step 1 is to calculate the total drops (gtt) the nurse needs to administer. This is done by multiplying the volume of the solution (400 mL) by the drop factor (60 gtt/mL). So, 400 mL × 60 gtt/mL = 24000 gtt.

Step 2 is to calculate the total time in minutes over which the IV should be administered. Since there are 60 minutes in an hour, 8 hours is equivalent to 8 hours × 60 min/hour = 480 minutes.

Step 3 is to calculate the rate at which the IV should be administered. This is done by dividing the total drops by the total time. So, 24000 gtt ÷ 480 min = 50 gtt/min.

The nurse should set the manual IV infusion to deliver approximately 50 gtt/min.

A. "I will be placing some electrodes on your chest and extremities." B. "Be sure to remain still once I have attached the gel pads." C. "You might feel some slight pressure during the procedure." D. "The test will be complete in a few minutes."

Correct Answer is A

Explanation

Choice A reason : This instruction is accurate because for a standard 12-lead ECG, electrodes are placed on the patient's chest and extremities to record the electrical activity of the heart. The placement of these electrodes is crucial for accurate readings and diagnosis. The electrodes do not emit electricity; they merely record and measure the electrical activity in your heart, providing essential information to the medical provider.

Choice B reason : Remaining still during an ECG is important to prevent artifacts that can interfere with the interpretation of the heart's electrical activity. Movement can cause the readings to be inaccurate, which is why patients are advised to remain still once the electrodes are in place.

Choice C reason : While the client might feel some pressure from the electrodes, the term 'tingling' is not accurate as the ECG is a painless procedure. The electrodes may cause mild irritation upon the skin, but there is otherwise no sensation associated with the test itself.

Choice D reason : The duration of the test is indeed short, typically only a few minutes, but this is not the primary instruction. The nurse should first inform the client about the electrode placement, which is essential for the procedure. The ECG will only take a few minutes in total once the procedure is underway, not counting equipment set-up time.
