Step 1: Understanding the Question:
We need to pick the FALSE statement about dental care in an adult with hemophilia (low factor VIII or IX).
Step 2: Key Formula or Approach:
Go through each option and check it against standard hemophilia dental-care protocol: factor cover, anesthesia technique, infection screening, and GA precautions.
Step 3: Detailed Explanation:
Cryoprecipitate or factor VIII concentrate is standard cover before extractions, so that option is a true statement.
HIV screening is done because many hemophiliacs had past exposure to pooled blood products, so that option is also true.
If general anesthesia is used, monitored, factor-covered GA care is standard, so that option is true as well.
The lidocaine dose is not raised in hemophilia. What changes is technique: infiltration is chosen over a nerve block, because a block can injure a vessel deep in tissue and start a hematoma that is difficult to control.
Step 4: Final Answer:
The false statement is that the dose of lidocaine required is increased.
