Your friend Joe recently visited the doctor for steroid injections into his knee to reduce swelling due to previous knee injury. Within a couple of days, he had an infection caused by Pseudomonas, a very pathogenic and drug resistant bacterium. Luckily, Joe went to the doctor immediately and received antibiotics. The doctor tells him that problem has occurred to many other people across the U.S. Predict the most likely cause of this situation:
The staff giving the steroid injections did not use proper aseptic technique.
The steroid was contaminated at the production plant, so all batches of that drug made at that plant were contaminated with the bacterium.
The bacterium is normally on the skin of people, so can easily access the patient's blood during the needle stick.
The needles were re-used and already contaminated before being used on the patients.
The Correct Answer is B
A. The staff giving the steroid injections did not use proper aseptic technique: Improper aseptic technique at a single clinic could cause local infections, but widespread cases across the U.S. point to a source affecting multiple clinics or batches rather than isolated procedure lapses.
B. The steroid was contaminated at the production plant, so all batches of that drug made at that plant were contaminated with the bacterium: Contamination during manufacture or compounding that led to distribution of contaminated batches nationwide can explain many cases across broad geographic areas and rapid onset after administration.
C. The bacterium is normally on the skin of people, so can easily access the patient's blood during the needle stick: While skin flora can cause infections after injections, Pseudomonas is primarily environmental and widespread patient infections clustered nationally are less consistent with routine skin flora transmission.
D. The needles were re-used and already contaminated before being used on the patients: Reused needles can cause outbreaks but would more likely produce clusters tied to a particular clinic or practitioner rather than many unrelated patients across the country.

Correct Answer is B
Explanation
A. It is a structural component of ribosomes: That describes rRNA rather than mRNA.
B. It carries genetic information from DNA for the purpose of synthesizing a polypeptide (protein): Messenger RNA conveys the coding sequence from DNA to the ribosome where it directs polypeptide assembly.
C. It contains an anticodon: Anticodons are features of tRNA that pair with mRNA codons; mRNA contains codons, not anticodons.
D. The ribose of its nucleotides is missing an oxygen: Missing an oxygen on the 2′ carbon describes deoxyribose in DNA nucleotides; RNA nucleotides (including mRNA) have ribose with the 2′ oxygen present.
