Question 1 of 5
Which finding would necessitate an immediate change in the therapeutic plan for a patient with grade 2 hepatic encephalopathy?
Correct Answer: B
Rationale: A positive urine pregnancy test would require an immediate change in the therapeutic plan for a patient with grade 2 hepatic encephalopathy due to the teratogenic effects of ribavirin. Ribavirin needs to be discontinued immediately to prevent harm to the fetus. The other options, weight loss, hemoglobin level, and complaints of nausea and anorexia, are common adverse effects of the prescribed regimen and may necessitate interventions such as patient education or supportive care, but they would not mandate an immediate cessation of therapy as in the case of a positive pregnancy test.
Question 2 of 5
Which response by the nurse best explains the purpose of ranitidine (Zantac) for a patient admitted with bleeding esophageal varices?
Correct Answer: C
Rationale: The correct answer is: 'The medication will prevent irritation of the enlarged veins.' Esophageal varices are dilated submucosal veins. The therapeutic action of H2-receptor blockers in patients with esophageal varices is to prevent irritation and bleeding from the varices caused by reflux of acidic gastric contents. While ranitidine can decrease the risk of peptic ulcers, reduce nausea, and help prevent aspiration pneumonia, the primary purpose of H2-receptor blockade in this patient is to prevent irritation and bleeding from the varices, not the other listed effects.
Question 3 of 5
After an unimmunized individual is exposed to hepatitis B through a needle-stick injury, which actions will the nurse plan to take (select one that does not apply)?
Correct Answer: C
Rationale: In the case of exposure to hepatitis B, the nurse should plan to administer hepatitis B vaccine to provide active immunity. Testing for antibodies to hepatitis B is essential to determine the individual's immune status. Giving hepatitis B immune globulin is necessary for passive immunity in cases of exposure. However, teaching about alpha-interferon therapy is not part of the standard management for hepatitis B exposure. Interferon therapy and oral antivirals are typically used in the treatment of chronic hepatitis B infections, not for prophylaxis after exposure.
Question 4 of 5
Why is it important to genotype HCV before initiating drug therapy?
Correct Answer: B
Rationale: Genotyping of HCV plays a crucial role in managing treatment as it helps determine the most effective therapy for the specific viral strain. It allows healthcare providers to personalize treatment regimens and predict response rates. The statement about acute HCV infection converting to chronic state is accurate, highlighting the need for appropriate management. Immune globulin and vaccines are not available for HCV, and Ribavirin is commonly used for chronic HCV infection. Improving appetite is essential in liver health as adequate nutritional intake supports hepatocyte regeneration.
Choices A, C, and D are incorrect as they do not address the specific importance of genotyping in HCV treatment or the significance of appetite improvement in liver function.
Question 5 of 5
A 3-year-old had a hip spica cast applied 2 hours ago. In order to facilitate drying, the nurse should:
Correct Answer: A
Rationale: After a hip spica cast is applied, it is important to facilitate drying by exposing the cast to air and turning the child frequently, approximately every 2 hours. This helps ensure even drying and prevents skin breakdown. Using a heat lamp can cause burns and should be avoided. Handling the cast with the abductor bar is not necessary for the drying process and may cause discomfort to the child. Turning the child as little as possible is not recommended as regular turning helps prevent complications like pressure ulcers and stiffness.
