The nurse is caring for a client who has been prescribed a fluoroquinolone for the treatment of a respiratory infection
The nurse is explaining to the client that this class of medications affects DNA replication by inhibiting the ______ strands of DNA from migrating to the opposite sides of the cell therefore inhibiting division.
Standard Text: Record your answer rounding to the nearest whole number.
Fill in the blank with the appropriate word.
Correct Answer: 2
Rationale: The fluoroquinolone antibiotics act on two enzymes in the DNA replication process. First, they bind to DNA gyrase, inhibiting its ability to relax the supercoiling of the bacterial DNA. When the replication enzymes reach an area still in a supercoiled state, replication terminates. A second mechanism is binding to topoisomerase IV. When this occurs, the two daughter DNA strands cannot migrate to opposite sides of the cell, and division cannot be completed.

Differentiate among quality improvement (QI), research, and evidence-based practice (EBP) by choosing the statement that is accurate
1. Statistical language in research is much more sophisticated than that used in QI. 2. Research and EBP support clinical decision making whereas QI is a monitoring program. 3. Quality improvement efforts help to generate new knowledge in the care of patients. 4. Quality improvement is not dependent upon a specific theory as is research and EBP.
