OUTCOME 2.2
1. The thyroid gland metabolizes iodine, the most common
form of which has a molecular weight of 127 (iodine-127).
A physician wants to use a radioactive isotope of iodine
(iodine-131) to test whether a patient’s thyroid gland is
metabolizing normally. Based on what you know about how
atoms react, do you think this physician’s plan makes sense?
OUTCOME 2.2
2. How would you reassure a patient about to undergo CT
scanning for evaluation of a tumor and fears becoming a
radiation hazard to family members?
OUTCOMES 2.2, 2.3
3. What acidic and basic substances do you encounter in your
everyday activities? What acidic foods do you eat regularly?
What basic foods do you eat?
INTEGRATIVE ASSESSMENTS/CRITICAL THINKING
OUTCOME 2.3
4. A man on a very low-fat diet proclaims to his friend, “I’m
going to get my cholesterol down to zero!” Is this desirable?
Why or why not?
OUTCOME 2.3
5. How would you explain the importance of amino acids and
proteins in a diet to a person following a diet composed
primarily of carbohydrates?
OUTCOME 2.3
6. Explain why the symptoms of many inherited diseases result
from abnormal protein function.
OUTCOME 2.3
7. A friend, while frying eggs, points to the change in the egg
white (which contains a protein called albumin) and explains
that if the conformation of a protein changes, it will no longer
have the same properties and will lose its ability to function.
