Question 1 of 5
Which enzyme catalyzes the addition of deoxynucleotides to the 3'OH ends of DNA molecules?
Correct Answer: C
Rationale: The correct answer is C: Terminal deoxynucleotidyl transferase (TdT). TdT catalyzes the addition of deoxynucleotides to the 3'OH ends of DNA molecules. It does so by adding nucleotides in a template-independent manner, making it crucial for generating diversity in immune cell receptor genes. A: Phosphohydrolase - This enzyme is not involved in adding deoxynucleotides to DNA ends. B: T4 DNA ligase - This enzyme catalyzes the joining of DNA fragments, not the addition of deoxynucleotides. D: DNA endonuclease - This enzyme cleaves DNA internally, not involved in adding deoxynucleotides to DNA ends.

Question 5 of 5
You have suffered a needle stick injury after giving a patient an IM injection,but you have no information about the patient’s HIV status. What is the most appropriate method for obtaining this information about the patient?
Correct Answer: C
Rationale: The occupational health nurse is trained to handle situations involving potential exposure to bloodborne pathogens. They can appropriately discuss the need for HIV testing with the patient and ensure that the process is handled confidentially and professionally. The nurse manager and the injured nurse should not directly approach the patient about this sensitive issue.
