Question 1 of 5
Which of the following statements is incorrect?
Correct Answer: D
Rationale: The correct answer is D because BLASTN searches nucleotide databases, not protein databases. BLASTN uses a nucleotide sequence as the query to find similar sequences in nucleotide databases. This is different from BLASTX, which searches protein databases using translated nucleotide sequences (answer A is correct). TBLASTX and TBLASTN translate the query sequence into six reading frames to search for similarities in both nucleotide and protein databases (answer C is correct). BLASTN is specifically designed for nucleotide sequence searches, making statement D incorrect.

Question 4 of 5
You give an intradermal injection of allergen to a patient who is undergoing skin testing for allergies. A few minutes later,the patient complains about feeling anxious short of breath and dizzy. You notice that the patient has reddened blotches on the face and arms. All of these therapies are available on your emergency cart. Which action should you take first?
Correct Answer: C
Rationale: The patient is showing signs of anaphylaxis,a life-threatening allergic reaction. The first priority is to administer epinephrine which acts quickly to reverse the symptoms by constricting blood vessels relaxing airway muscles and increasing heart rate. Oxygen and IV access are important but secondary to the immediate administration of epinephrine. Albuterol may be used for bronchospasm but is not the first-line treatment for anaphylaxis.
