If the user has dropped 3 Non-Nodal Target Lesions, how many Nodal Lesions can be dropped as well?
- A.
1
- B.
3
- C.
5
- D.
2
Correct Answer
D. 2Explanation
If the user has dropped 3 Non-Nodal Target Lesions, they can drop a maximum of 2 Nodal Lesions as well. This is because the total number of lesions that can be dropped is determined by the sum of the number of Non-Nodal Target Lesions and the number of Nodal Lesions. In this case, since 3 Non-Nodal Target Lesions have already been dropped, the user can drop a maximum of 2 Nodal Lesions.Rate this question:

- 5.
The same locations may not be used for more than one target lesion (Nodal and Non-Nodal).
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is saying that the same locations cannot be used for both nodal and non-nodal target lesions. In other words, if a location is chosen as a target lesion for nodal assessment, it cannot also be used as a target lesion for non-nodal assessment. This means that different locations need to be chosen for each type of assessment. The correct answer is False, meaning that the statement is not true.Rate this question:
-
- 6.
If the location for a target lesion is 'X-specify' (where X is equal to an anatomical location), the following will be required:
- A.
Multi-select other locations for clarification
- B.
Mark lesion as not evaluable
- C.
Enter comments for location description
- D.
Select a different location
Correct Answer
C. Enter comments for location descriptionExplanation
When the location for a target lesion is specified as 'X', it is necessary to enter comments for location description. This is because simply specifying 'X' may not provide sufficient information about the exact location of the lesion. By entering comments for location description, additional details can be provided to clarify the location of the lesion. This helps in ensuring accurate evaluation and interpretation of the target lesion.Rate this question:
-
- 7.
The maximum allowed amount of target lesions with the same organ location is ___.
Correct Answer
2Explanation
The maximum allowed amount of target lesions with the same organ location is 2. This means that in a clinical trial or study, a maximum of 2 target lesions can be present in the same organ location for evaluation and assessment purposes. This limit is set to ensure that the evaluation of response to treatment remains accurate and manageable. Having more than 2 lesions in the same organ location could potentially complicate the assessment process and make it more difficult to determine the effectiveness of the treatment.Rate this question:
