Health search tasks.

Task ID	Task description
Task 1	During the past six days, your skin has been very itchy and dry, particularly on your arm, wrist, and leg areas. You also noticed the appearance of rashes and redness on your itchy skin. You want to find out what might happen to your skin and how to treat it.
Task 2	In a first aid training course, your instructor emphasizes that lay people need to understand sudden cardiac arrest (SCA). SCA is often equated incorrectly with a heart attack, but SCA victims can survive if they receive treatment within 3-5 min after they collapse. You want to know (1) the difference between a heart attack and an SCA, and (2) how a lay person can help a victim when a suspected SCA incident happens in a public area.
Task 3	Every year your institution holds a mandatory general medical check-up. One of the medical tests is urinalysis. You usually receive the results about 3 weeks after the test. You want to know the purpose of each parameter (why each parameter is tested) in the sample below and the meaning of the results (normal or abnormal). Specific gravity: 1.030 (reference interval: 1.002-1.030) pH: 4.9 (reference interval: 4.6-7.5) Protein: Negative (reference interval: negative) Glucose: 100 mg/dL (reference interval: negative)
Task 4	Your doctor prescribed simvastatin and instructed you not to consume the medicine with grapefruit juice. You want to know the purpose of simvastatin and why it should not be consumed with grapefruit juice.
