A client who has been hospitalized with a viral infection asks the nurse why the doctor did not prescribe a medication. The nurse explains that with some viruses, drug therapy is not warranted because:
 
  1. some viruses are self-limiting, and adverse effects can occur.
  2. the drugs are not strong enough for effective treatment.
  3. most drugs work for only a short period.
  4. some drugs work only on prevention, not treatment.

Question 2

Antiviral medications work by inhibiting or stopping a stage of viral replication. Which statements are descriptions of these stages?
 
  Standard Text: Select all that apply.
  Choice 1. Attachment of the virus to the host cell
  Choice 2. Destruction of host cell DNA.
  Choice 3. Synthesis of the viral nucleic acid and proteins by the host cell
  Choice 4. Assembly of all viral components, structural proteins, enzymes, and nucleic acids
  Choice 5. Release of virions from the host cell

Answer to Question 1

Correct Answer: 1
Rationale 1: Some viruses are self-limiting, and the adverse effects of drug therapy can be worse than the symptoms of the viral infection itself.
Rationale 2: Many drugs are available for effective treatment.
Rationale 3: Many drugs work for an extended period.
Rationale 4: Many drugs are available for prevention and treatment of viruses.
Global Rationale: Some viruses are self-limiting, and the adverse effects of drug therapy can be worse than the symptoms of the viral infection itself. Effective drugs are available if the benefits of use outweigh the risks of use. These drugs may work for extended times. Drugs for prevention and treatment are available.

Answer to Question 2

Correct Answer: 1,3,4,5
Rationale 1: The first stage of viral infection is the attachment of the virus to the host cell.
Rationale 2: Destruction of host cell DNA is not a stage of infection.
Rationale 3: The third stage of viral infection is synthesis of the viral nucleic acid and proteins by the host cell.
Rationale 4: The fourth stage of viral infection is assembly. All the viral components, structural proteins, enzymes, and nucleic acids are packaged and made ready to leave the cell.
Rationale 5: The fifth stage of viral infection is the release of the virions from the host cell.
Global Rationale: The stages of viral infection are attachment of the virus to the host cell, penetration, synthesis, assembly, and release of the virions from the host cell.
