A nursing student asks a nurse how antibacterials work. The nurse outlines the process, explaining that many antibacterials work by blocking bacterial DNA replication. The nurse knows further teaching is needed when the student states:
 
  1. Drugs inhibit the availability of precursor bases or nucleotides.
  2. Drugs can interact or bind with DNA, preventing the uncoiling or relaxation process.
  3. Drugs can bind to enzymes of DNA replication, halting the formation of new DNA strands.
  4. Drugs repair bacterial DNA damage.

Question 2

Many medications are developed in hopes of treating cancer. Many of these cancer drugs work by:
 
  1. Encouraging cell replication.
  2. Forming new DNA.
  3. Assisting in the repair of DNA damage.
  4. Substituting the drug into the DNA of the cancer cell.

Answer to Question 1

Correct Answer: 4
Rationale 1: This is one of the ways in that antibacterials block bacterial DNA replication.
Rationale 2: This is one of the ways in that antibacterials block bacterial DNA replication.
Rationale 3: This is one of the ways in that antibacterials block bacterial DNA replication.
Rationale 4: Drugs that block bacterial DNA replication would block the repair of the DNA, not allow it.
Global Rationale: Drugs that block bacterial DNA replication would block the repair of the DNA, not allow it. Drugs block bacterial DNA replication by inhibiting synthesis of precursor bases or nucleotides, binding to bacterial DNA, and binding to the enzymes needed for replication.

Answer to Question 2

Correct Answer: 4
Rationale 1: Many medications developed for the treatment of cancer work by inhibiting the replication of the cell, not encouraging it.
Rationale 2: The cancer drugs work to halt the formation of new DNA strands.
Rationale 3: Cancer drugs can act by inhibiting an enzyme that helps repair DNA damage, thereby preventing the repair of DNA.
Rationale 4: Cancer drugs can work by mimicking molecules that are mistakenly incorporated into newly formed DNA, preventing its replication.
Global Rationale: Cancer drugs can work by mimicking molecules that are mistakenly incorporated into newly formed DNA, preventing its replication. Many medications developed for the treatment of cancer work by inhibiting the replication of the cell, not encouraging it. The cancer drugs work to halt the formation of new DNA strands. Cancer drugs can act by inhibiting an enzyme that helps repair DNA damage, thereby preventing the repair of DNA.
