Question 1 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 2 of 5
A client is in the post-anesthesia care unit (PACU) shivering despite being covered with several layers of blankets. What is the nurse's next action?
Correct Answer: C
Rationale: In the post-anesthesia care unit, clients may experience shivering or chills due to a drop in body temperature after surgery. Meperidine (Demerol) can be prescribed to alleviate shivering in cold clients. The prone position (lying face down) and deep breathing exercises are not interventions specifically indicated for addressing shivering due to low body temperature.
Therefore, administering meperidine as ordered is the most appropriate action to manage the client's shivering in this scenario.
Question 3 of 5
A 36-year-old male patient in the outpatient clinic is diagnosed with acute hepatitis C (HCV) infection. Which action by the nurse is appropriate?
Correct Answer: A
Rationale: The correct action by the nurse is to schedule the patient for HCV genotype testing. Genotyping of HCV is crucial in determining the appropriate treatment regimen and guiding therapy decisions. Most patients with acute HCV infection progress to the chronic stage, so it is incorrect to inform the patient that the infection will resolve in a few months. There is no vaccine or immune globulin available for HCV, and ribavirin (Rebetol) is typically used for chronic HCV infection.
Therefore, the nurse should prioritize genotyping to assist in treatment planning.
Question 4 of 5
A man is prescribed lithium to treat bipolar disorder. The nurse is most concerned about lithium toxicity when he notices which of these assessment findings?
Correct Answer: B
Rationale: The correct answer is when the patient states he has been having diarrhea every day. Persistent diarrhea can lead to dehydration, which can increase the risk of lithium toxicity. The other options, such as a manic episode, severe depression, or rash and pruritus, are not directly associated with an increased risk of lithium toxicity.
Question 5 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.
