Exam & Evaluation (High Altitude Sickness)
Questions: Please respond to following statements.
There are 3 primary types of high altitude sickness: Acute mountain sickness (AMS), high altitude cerebral edema (HACE), and high altitude pulmonary edema (HAPE).
Normal acclimatization includes symptoms such as hyperventilation, increased urination, and Cheyne-Stokes breathing.
A mild headache is a normal part of acclimatization and is no cause for concern.
A person with moderate AMS should remain at the same elevation or descend but not ascend any further.
The inability to walk a straight line, heel to toe, is a sign of ataxia and is cause for concern.
HACE can result in convulsions, coma, and death if not treated promptly.
People with HACE should be left at the same altitude until their symptoms resolve.
HAPE occurs when fluid leaks from the blood vessels into the lungs.
Hyperbaric treatment is used for HACE but not HAPE.
Subacute infantile mountain sickness is rarely fatal because infants adjust to the high altitude better than adults.
Chronic mountain sickness (CMS) involves high altitude heart disease (HAHD), with or without polycythemia.
The main characteristics of HAHD are enlarged heart, right ventricular hypertrophy, and right heart failure due to severe pulmonary hypertension.
HAHD is an increasing problem in China.
Because people move from high elevation to low
Because people move from low elevation to high.
Because people travel to and from high elevations.
Because the Chinese are prone to heart disease.
Most deaths from high altitude sickness occur in travelers _________:
Who travel alone or with one or two friends.
Who travel in isolated areas.
Who complain about symptoms.
Who are part of organized group treks to high altitude locations.
Is used to prevent or treat AMS.
Is used to prevent or treat HACE.
Is used to prevent or treat HAPE.
Is used to prevent or treat HACE and HAPE.
Is used to prevent AMS.
Is used to treat HAPE.
Is used to prevent HACE.
Is used to treat AMS and HACE while trying to descend.
Treatment with portable hyperbaric chambers
Are used to treat both HAPE and HACE.
Are portable and can be carried as a backpack.
Is widely used among travel tours, trekking groups, and mountain climbing expeditions.
All of the above.
Contradictions to using the portable hyperbaric chambers include:
Person using oxygen from small tank.
Severely cold weather.
Direct sunlight at high altitude.
Person is not breathing.
People with the following pre-existing condition should ALWAYS avoid higher elevations:
Sickle cell anemia
All of the above.
Women who are pregnant
Should seek medical advice about the risks of high elevation travel.
Should avoid elevations above 12,000 feet
Should evaluate access to emergency obstetrical care at high altitude
All of the above.
A simplified version of the rules of prevention is
Always go down with AMS and never go up with HACE and HAPE
Never go up with AMS, HACE, or HAPE
Never go up with AMS and always go down with HACE and HAPE
Always go down with AMS, HACE, and HAPE
If feeling symptoms of AMS, including headache and fatigue______
Be sure to limit fluid intake.
Descend, even if symptoms improve with rest.
Have a glass of wine to relax.
