What is the function of inflammatory cytokines released during the early response to bacterial infection?
A. Enhancing the phagocytosis of pathogens and disrupting the infection
B. Attacking invading pathogens
C. Initiating cell recruitment and local inflammation
D. Secreting antibodies to neutralize pathogens .
Inflammatory cytokines released during the early response to bacterial infection play a crucial role in initiating cell recruitment and local inflammation 1.
They induce the expression of adhesion molecules in endothelial cells and promote the recruitment of neutrophils to the site of inflammation 1.
Choice A is incorrect because while inflammatory cytokines may enhance phagocytosis, they do not directly disrupt the infection.
Choice B is incorrect because inflammatory cytokines do not directly attack invading pathogens.
Choice D is incorrect because inflammatory cytokines do not secrete antibodies to neutralize pathogens.
Therefore, the Correct Answer is C.

Q #1: A nurse is reviewing the results of a patient’s DNA sequencing test, which was performed to diagnose a genetic disorder. The nurse notices that the patient has a mutation in one of the bases of the DNA. Which of the following is the correct term for this type of mutation?
A. Deletion
B. Insertion
C. Substitution
D. Inversion
Answer Explanation
The correct answer is choice C. Substitution.
A substitution mutation is a type of point mutation where one base in the DNA sequence is replaced by another base.
Choice A is incorrect because a deletion mutation occurs when one or more bases are removed from the DNA sequence.
Choice B is incorrect because an insertion mutation occurs when one or more bases are added to the DNA sequence.
Choice D is incorrect because an inversion mutation occurs when a segment of DNA is reversed within the chromosome.

Q #2: What is the largest vein in the human body that returns deoxygenated blood from the upper half of the body to the right atrium of the heart?
A. Superior vena cava.
B. Inferior vena cava.
C. Pulmonary vein.
D. Renal vein.
Answer Explanation
The correct answer is choice A.
The superior vena cava is the largest vein in the human body that returns deoxygenated blood from the upper half of the body to the right atrium of the heart.
Choice B is incorrect because the inferior vena cava returns deoxygenated blood from the lower half of the body to the right atrium of the heart.
Choice C is incorrect because the pulmonary vein carries oxygenated blood from the lungs to the left atrium of the heart.
Choice D is incorrect because the renal vein carries deoxygenated blood from the kidneys to the inferior vena cava.

Q #3: What are the four nucleotide bases found in DNA?
A. Adenine, Thymine, Cytosine, Guanine.
B. Adenine, Thymidine, Cytidine, Guanine.
C. Adenosine, Thymine, Cytosine, Guanosine.
D. Adenosine, Thymidine, Cytidine, Guanosine.
Answer Explanation
These are the four nucleotide bases found in DNA1.
Choice B) Adenine, Thymidine, Cytidine, Guanine is incorrect because Thymidine and Cytidine are not nucleotide bases found in DNA.
Choice C) Adenosine, Thymine, Cytosine, Guanosine is incorrect because Adenosine and Guanosine are not nucleotide bases found in DNA.
Choice D) Adenosine, Thymidine, Cytidine, Guanosine is incorrect because Adenosine, Thymidine and Cytidine are not nucleotide bases found in DNA.
