1 Created by Boundless The common cold is best described as: A a viral infectious disease of the upper respiratory tract that primarily affects the nose B a viral infectious disease that produces an immune response that damages the nasal epithelium C a viral infectious disease that can be treated with a wide range of antibiotics D a viral infectious disease of the lower respiratory tract that primarily affects the alveoli 2 Created by Boundless The most commonly implicated virus in the common cold is the rhinovirus. Which of the following best describes this rhinovirus? A It is a non-enveloped RNA virus B It is an enveloped DNA virus C It is a non-enveloped DNA virus D It is an enveloped RNA virus 3 Created by Boundless Pneumonia can be caused by either viral or bacterial infections. Which of the following statements is NOT correct in regards to the viral route of infection? A The virus, upon invasion of the airway and alveoli, will directly kill the cells or cause apoptosis B The virus enters the respiratory system by entering the mouth and nose via droplets C The immune system response damages the lungs by activating agents that fill the alveoli with fluid D The virus infects the alveoli, replicates and releases viruses which cause fluid to fill the alveoli 4 Created by Boundless Which of the following characteristic can be associated with the human respiratory syncytial virus (RSV)? A RSV is a negative-sense, single stranded DNA virus B RSV is a negative-sense, single stranded RNA virus C RSV is a negative-sense, double stranded RNA virus D RSV is a negative-sense, double stranded DNA virus 5 Created by Boundless Which of the following is a unique characteristic of the human respiratory syncytial virus (RSV)? 6 A The expression of F proteins on its surface that results in the merging of nearby cell membranes B The expression of M proteins required for viral fusion protein synthesis that enter the host cell C The expression of G proteins responsible for transferring genomic RNA to the host D The expression of SH proteins that are needed to form syncytia Created by Boundless Choose the answer that best describes coryza, a respiratory system disorder. A caused by family of viruses that affect both birds and mammals B viral infection causing chills, fever, aches, fatigue C inflammation of mucous membranes of nasal cavity that may be viral or allergenic in nature D caused by RNA virus with rapidly-evolving protein 'coat' requiring new vaccinations each year
