A nurse is performing an 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.
I will need to apply electrodes to your chest and extremities.
You might feel a slight tingling while the test is being done.
The radioactivity from the dye lasts only a few hours.
The Correct Answer is B
Choice A rationale
ECG tests usually take 5 to 10 minutes to complete. The patient's chest pain necessitates a quick assessment, and prolonged testing could delay urgent care.
Choice B rationale
Electrodes applied to the chest and extremities detect the electrical activity of the heart, necessary for accurate ECG readings and diagnosing potential cardiac issues.
Choice C rationale
The ECG procedure does not typically cause tingling sensations. It involves passive measurement of electrical signals, making this statement inaccurate and potentially alarming to the patient.
Choice D rationale
ECG tests do not involve dye or radioactivity. This confusion may arise from nuclear stress tests, which are different procedures for evaluating heart function.

Correct Answer is C
Explanation
Choice A rationale
Increased PAWP indicates left-sided heart failure, as it measures pressure in the left atrium and left ventricle. Right-sided heart failure typically presents with systemic venous congestion rather than pulmonary congestion. Normal PAWP: 6-12 mmHg.
Choice B rationale
Decreased specific gravity is not a typical finding in right-sided heart failure. Specific gravity measures urine concentration and can vary based on fluid intake and kidney function. Normal range: 1.005-1.030.
Choice C rationale
Ascending dependent edema results from increased venous pressure and fluid retention in the lower extremities, common in right-sided heart failure due to impaired venous return and fluid overload.
Choice D rationale
Decreased BNP is not characteristic of heart failure. BNP levels increase in response to ventricular volume expansion and pressure overload. Elevated BNP aids in diagnosing heart failure. Normal BNP: <100 pg/mL. .
Correct Answer is A
Explanation
Choice A rationale
The first upward deflection in an ECG represents the P wave, indicating atrial depolarization. It precedes the QRS complex and corresponds to the electrical activity associated with atrial contraction, initiating the cardiac cycle.
Choice B rationale
The peak of the first wave corresponds to the R wave, not the P wave. The R wave is a part of the QRS complex, representing ventricular depolarization, and is not associated with atrial depolarization.
Choice C rationale
The downward deflection following the peak is the S wave, part of the QRS complex, indicating ventricular depolarization. It is not related to the P wave, which specifically represents atrial depolarization.
Choice D rationale
The second upward deflection is the T wave, which represents ventricular repolarization. It follows the QRS complex and is not associated with atrial depolarization or the P wave.
