Question 1 of 5
Which of the following nucleotide triplets best represents a codon?
Correct Answer: A
Rationale: The correct answer is A because a codon is a triplet of nucleotides in mRNA that corresponds to a specific amino acid during protein synthesis. To be a codon, the triplet must be in the same reading frame as the start codon (AUG) to maintain the correct reading of the genetic code. Choice B is incorrect because codons are typically consecutive in mRNA. Choice C is incorrect as tRNA sequences are not codons. Choice D is incorrect because all codons correspond to specific amino acids.

Question 5 of 5
A patient with acquired immunodeficiency syndrome (AIDS) has a negative tuberculosis (TB) skin test. Which nursing action is indicated next?
Correct Answer: A
Rationale: A negative TB skin test in an immunocompromised patient such as one with AIDS does not rule out TB infection. Further diagnostic testing such as a chest x-ray and sputum smear is necessary to confirm the absence of TB. Teaching about INH or scheduling another test is premature without further diagnostic confirmation.
