The nurse notes that several clients prescribed supplemental thyroid hormone are all receiving different doses of the same drug. The nurse recognizes that this variation is mostly driven by:
1. the client's age and ethnicity.
2. the client's psychological status and acceptance of hormone therapy.
3. the number and sensitivity of the individual client's tissue receptors.
4. the client's height and weight.
Correct Answer: 3
Rationale 1: Dose variation is not based on age or ethnicity.
Rationale 2: Dose variation is not based on psychological status or acceptance of hormone therapy.
Rationale 3: The primary reasons for dose variations are the differences in the number of receptors and in their sensitivity. Each client presents a therapeutic challenge.
Rationale 4: Height and weight are less important than another factor.
Global Rationale: The primary reasons for dose variations are the differences in the number of receptors and in their sensitivity. Each client presents a therapeutic challenge. Age, ethnicity, psychological status, acceptance of hormone therapy, and height and weight are less important than individual differences in receptors.
