The ten-year-old child was diagnosed with a medulloblastoma; following surgery the child is started on chemotherapy by intrathecal injection
While preparing the family for the start of chemotherapy, the nurse will explain that intrathecal administration was chosen because: 1. It reduces side effects.
2. It does not require the child being "stuck."
3. Many chemotherapy drugs do not cross the blood-brain barrier.
4. Intrathecal administration is less expensive than intravenous administration.
3
Rationale 1: Intrathecal administration does not reduce side effects.
Rationale 2: Intrathecal administration is through a spinal tap, so the child will be "stuck" for administration.
Rationale 3: This is the correct rationale for the selection of intrathecal administration of chemotherapy.
Rationale 4: This is not accurate and would not be a reason to change administration modes.
