Question 3 of 5
A client is receiving the cell cycle-nonspecific alkylating agent thiotepa (thioplex), 60 mg weekly for 4 weeks by bladder instillation as part of a chemotherapeutic regimen to treat bladder cancer. The client asks the nurse how the drug works. How does thiotepa exert its therapeutic effects?
Correct Answer: C
Rationale: Thiotepa is a cell cycle-nonspecific alkylating agent that exerts its therapeutic effects by interfering with both DNA replication and RNA transcription. The alkylating properties of thiotepa lead to the cross-linking of DNA strands, ultimately inhibiting DNA replication. Additionally, thiotepa can also disrupt RNA synthesis, further affecting protein production and cell function. This combined action on DNA replication and RNA transcription contributes to the cytotoxic effects of thiotepa on rapidly dividing cancer cells.

Question 5 of 5
Which of the following procedures does the nurse understand is used to correct otosclerosis?
Correct Answer: D
Rationale: Otosclerosis is a condition characterized by abnormal bone growth in the middle ear, particularly around the stapes bone. A stapedectomy is a surgical procedure performed to correct otosclerosis by removing the stapes bone and replacing it with a prosthesis. This surgery aims to improve hearing by restoring the movement of the ossicles in the middle ear. Myringotomy is a procedure involving an incision in the eardrum to drain fluid, mastoidectomy involves the removal of infected mastoid air cells, and myringoplasty is the surgical repair of a perforated eardrum, none of which address the specific issue of otosclerosis.
