Audiometry is the most important diagnostic test for assessing hearing loss. This test measures a person's ability to hear sounds, varying in pitch and loudness. It is a comprehensive evaluation that helps determine the degree and type of hearing loss, whether it is conductive, sensorineural, or mixed. Tympanogram, middle ear endoscopy, and auditory brain stem response are also valuable diagnostic tools, but audiometry provides the primary assessment necessary for diagnosing hearing loss and guiding subsequent treatment.

Answer : D

Swimming is an excellent exercise for individuals with low back pain as it is low-impact and helps strengthen the muscles supporting the back without putting undue stress on it. Sit-ups and leg lifts can strain the back and worsen pain, while running is a high-impact activity that can also exacerbate back pain. Swimming promotes flexibility, strength, and cardiovascular health while minimizing the risk of further injury to the back.

Disaster Triage Principles:

In disaster scenarios, triage prioritizes patients based on the severity of their injuries and the likelihood of survival.

The goal is to provide the greatest good for the greatest number of people.

Triage Categories:

Immediate (Red): Life-threatening injuries requiring immediate intervention.

Delayed (Yellow): Serious injuries needing treatment but not immediately life-threatening.

Minor (Green): Minor injuries that can wait for treatment.

Expectant (Black): Injuries are so severe that survival is unlikely, even with treatment.

Case Analysis:

Conscious with Femur Fracture: Delayed category, serious but not immediately life-threatening.

Conscious with Superficial Cuts: Minor category, least priority but still above expectant.

Unconscious with Internal Bleeding: Immediate category, needs urgent intervention.

Unconscious with Open Skull Fracture and Brain Matter Showing: Expectant category, very low chance of survival, thus least priority.
