For effective sterilisation of endoscopes using Ethylene oxide the exposure time should be
- 2 hours
- 24 hours
- 6 hours
- 3 hours
Flexible endoscopes are poor in visualising
- Upper oesophagus
- Laryngeal inlet
- Mid oesophagus
- Hypopharynx
The frequency of light used to perform video stroboscopy is
- 2 Hz
- 8 Hz
- 24 Hz
- 55 Hz
Stroboscopy helps to differentiate benign from early malignant lesions of vocal cord by
- Identifying the mobility of vocal cord
- Identification of preservation of normal mucosal wave of vocal cord
- Visualising the lesion better
- Malignant lesions are seen in blue color
In vocal cord palsy the first sign of recovery as evident in stroboscopic examination is
- Return of visible travelling wave
- Vocal cord shows mobility
- Vocal cord on recovery becomes red in color
- Vocal cord on recovery becomes white in color
The best investigation for identifying isolated superior laryngeal nerve paralysis is
- Indirect laryngoscopy
- Direct laryngoscopy
- Video laryngoscopy
- Video stroboscopy
The Manouver BURP is used to
- Better visualise cricopharynx
- Vocal cords
- To visualised uvula
- To enter upper oesophagus
In BURP pressure is applied to
- Cricoid cartilage
- Hyoid bone
- Thyroid cartilage
- Nape of neck
Patient's position for bronchoscopy is called
- Rose position
- Boyce position
- Killian position
- Reverse killian position
Indirect laryngoscopy in adults is performed using a
- No 2 mirror
- No 1 mirror
- No 5 mirror
- No 3 mirror
To examine the throat a tongue depressor is used to depress which part of the tongue
- Anterior 1/3
- Posterior 1/3
- Lateral wall of the tongue
- The whole of the tongue
IDL mirror is warmed before performing the examination to
- Sterilise the mirror
- To make the mirror reflect light better
- To prevent fogging
- To make the patient comfortable
Spirit lamp is used to warm the IDL mirror because
- It generates uniform light
- It sterilises the mirror efficiently
- It does not blacken the mirror
- It makes the mirror bright
To warm the IDL mirror the spirit lamp must be used to
- Warm the metal side of the mirror
- Warm the glass side of the mirror
- Warm the handle of the mirror
- Warm the junction of glass and handle of the mirror
To examine the mouth the tongue depressor must be held
- In the dominant hand
- Right hand
- Any hand can be used
- Always it is held in right hand
During examination of a patient the Bull's lamp is placed
- Directly behind the patient
- To the right of the patient
- In front of the patient
- To the left and behind the patient
The bulb inside the Bull's lamp should be
- Flourescent bulb
- Ordinary white incandescent bulb
- Zero watt bulb
- 100 watt milk white bulb
The movement of soft palate is tested by
- Asking the patient to swallow
- Asking the patient to protrude the tongue
- Asking the patient to say AHHH
- Asking the patient to take a deep breath
Pooling of saliva in the pyriform fossa indicates
- Obstruction at the level of cricopharynx
- Obstruction at the level of stomach
- Obstruction at the level of ileum
- Obstruction at the level of large bowel
Kissing tonsils is
- Grade I tonsillar enlargment
- Grade V tonsillar enlargement
- Grade IV tonsillar enlargement
- Grade II tonsillar enlargement
