Answer:
c. The abnormality is in the thyroid gland itself.
Explanation:
Primary hypothyroidism arises from a pathology in the thyroid gland itself and occurs when the thyroid gland is not able to perform one of its many physiology. Secondary hypothyroidism starts at the level of the pituitary gland and results from under secretion of TSH. TSH is needed to trigger the release of the T3 and T4 stored in the thyroid gland. Tertiary hypothyroidism is caused by a decrease level of the TRH from the hypothalamus. This reduced level, in turn, reduces TSH and thyroid hormone levels in the blood, hence in the body and the patient suffer the symptoms.
Answer: The answer is C - clean room.
Explanation: You prepare a sterile IV medication in a clean room. A fume hood is used in a kitchen. You prepare a sterile IV medication in a clean room, ISO class 7 and inside that room is an ISO class 5 area - either an area that achieves this or inside a primary engineering control. A PEC is a laminar air flow hood - either horizontal or vertical. Or, if you do not have an ISO class 7 area, you can use a biological safety cabinet or Compounding Aseptic (CAI) and Containment Isolators (CACI) that can be certified to use a room that is less than ISO class 7. The only reason you would ever prepare a sterile IV medication on a counter is in an emergency situation for "immediate use." Immediate use is defined as the entire contents will be used within 60 minutes of the preparation.
