  1. AC interference on an ECG recording appears as:

    Answer: Uniform, rapid spikes at 60 cycles per second

    AC (alternating current) interference appears as uniform 60-cycle-per-second spikes superimposed on the ECG tracing, caused by nearby electrical equipment.

  2. Which position is BEST for a patient during a resting 12-lead ECG?

    Answer: Supine (lying flat)

    The patient should lie supine and still to minimize movement artifact and ensure consistent electrode placement and electrical contact.

  3. The T wave on an ECG represents:

    Answer: Ventricular repolarization

    The T wave represents ventricular repolarization, the electrical recovery phase of the ventricles after contraction.

  4. Which spirometry measurement represents the maximum amount of air forcefully exhaled after a maximum inhalation?

    Answer: Forced vital capacity (FVC)

    Forced vital capacity (FVC) is the total volume of air exhaled as forcefully and completely as possible after a maximum inhalation.

  5. Before performing a spirometry test, the patient should be instructed to:

    Answer: Avoid smoking for at least 4 hours and bronchodilators as directed

    Patients should avoid smoking for at least 4 hours before spirometry and withhold bronchodilator medications as directed to ensure accurate baseline measurements.

  6. A Holter monitor is used to:

    Answer: Record cardiac activity continuously over 24–48 hours

    A Holter monitor is a portable ECG device worn by the patient for 24–48 hours to detect intermittent cardiac arrhythmias not captured on a resting ECG.
