Answer:
The correct answer will be option-A
Explanation:
Electrocardiogram or ECG is the recording and representation of the electrical changes that are taking place during the cardiac cycle.
The QRS complex is preceded by the P wave or atrial systole or atrial depolarization after which the electrical signals are passed on to the AV node.
As soon as the AV node passes the electrical signals to bundle of His, it is observed in as the QRS interval which represents the atrial diastole and the onset of ventricular depolarization.
Thus, option-true is the correct answer.
Answer:
The pressure waves strike the tympanum, causing it to vibrate. The mechanical energy from the moving tympanum transmits the vibrations to the three bones of the middle ear. The stapes transmits the vibrations to a thin diaphragm called the oval window, which is the outermost structure of the inner ear.

the abnormalities the nurse can document during the otoscopic examination are immobility of the tympanic membrane and middle ear effusion.
<h3>What is otoscopy?</h3>
Otoscopy can be defined as a clinical procedure used in the examination of the structures of the ear, particularly the external auditory canal, tympanic membrane, and even the middle ear.
Clinicians carryout otoscopy during routine wellness physical exams and the evaluation of specific ear complaints
During the otoscopic examination, the clinician utilizes an otoscope, also to see through or to visualize the ear anatomy.
The abnormalities that can be documented include;
- Immobility of the tympanic membrane moves in response to pressure.
- The detection of middle ear effusion
Thus, the abnormalities the nurse can document during the otoscopic examination are immobility of the tympanic membrane and middle ear effusion.
