Exam 5: Viral Structure and Multiplication

A 5-month-old female, accompanied by her parents, presents to the pediatrician's office with a fever, dry mucous membranes, labored breathing, wheezing, and a harsh cough. Rapid testing of nasal swabs reveals respiratory syncytial virus infection. The RN arranges for transport to the hospital, where she will receive intravenous fluids and oxygen therapy. -What is the rationale for providing intravenous fluids and oxygen support for this patient?

Host cells of viruses include ________.

A negative-sense RNA virus ________.

Mammalian viruses capable of starting tumors are ________.

A 5-month-old female, accompanied by her parents, presents to the pediatrician's office with a fever, dry mucous membranes, labored breathing, wheezing, and a harsh cough. Rapid testing of nasal swabs reveals respiratory syncytial virus infection. The RN arranges for transport to the hospital, where she will receive intravenous fluids and oxygen therapy. -If the patient receives antibiotic therapy at the hospital,the RN would expect the patient's duration of symptoms to be ________.

It is necessary to culture viruses both in vivo and in vitro so that vaccines can be developed,analysis of viral genomes can be made and viruses in clinical specimens can be identified.

All of the following pertain to virus envelopes except ________.

An RN is in a long-term care facility is caring for a 79-year-old female. The patient has been a resident on in the facility for the past 5 years. She has been complaining of pain, burning, and tingling on her left side. Upon further assessment, the RN observes fluid-filled blisters wrapping around the left side of her torso in a concentrated strip. The facility physician diagnoses her with shingles and orders the appropriate isolation. -The patient asks the RN how she contracted this viral infection since she has not come in contact with anyone with anyone infected with shingles.Which of the following statements is an appropriate response?

Two noncellular agents,smaller than viruses,are the infectious proteins called ________ and the infectious RNA strands called ________.

An RN in a pediatric emergency department performs a triage patient on a 13-month-old male. The patient's father states he had difficulty waking his son from a nap that afternoon. Additionally, the infant had difficulty crawling and had difficulty with feeding the following morning. The RN observes that the patient has a weak cry. Upon further assessment, the patient's father noted that the infant had ingested fresh honey on his toast at breakfast yesterday. The medical team suspects Clostridium botulinum infection due to the ingestion of bacterial endospores. -The RN anticipates that the priority intervention for this patient's care will be ________.

Viral spikes are inserted into the host cell membrane before budding or exocytosis.

Lysogeny refers to ________.

A patient undergoing chemotherapy for cancer develops an infection with cytomegalovirus,conclusively diagnosed by the presence of "owl's eye" viral nuclear inclusions in a liver biopsy.  This is an example of a(n) ________.

Persistent viruses that can reactivate periodically are ________.

Spikes are glycoproteins of the virus capsid.

Infectious naked strands of RNA that affect plants are called ________.

Rapid testing of nasal swabs reveals respiratory syncytial virus infection. The RN arranges for transport to the hospital, where she will receive intravenous fluids and oxygen therapy. -The patient's parents question which antibiotic will be given to treat their daughter's infection.You inform her that ________.

Which of the following occurs during assembly of an enveloped virus?

Viruses with ________ -sense RNA contain the correct message for translation,while viruses with ________ -sense RNA must first be converted into a correct message.
