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)?
- A. Administer hepatitis B vaccine.
- B. Test for antibodies to hepatitis B.
- C. Teach about alpha-interferon therapy.
- D. Give hepatitis B immune globulin.
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.

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?
- A. The patient states he had a manic episode a week ago
- B. The patient states he has been having diarrhea every day
- C. The patient presents as severely depressed
- D. The patient has a rash and pruritus on his arms and legs
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.
Which patient poses the least infection risk to an immunosuppressed patient who had a liver transplant?
- A. The patient with chronic pancreatitis
- B. The patient currently infected with a respiratory virus
- C. The patient with a healing leg wound
- D. The patient with a urinary tract infection
Correct Answer: C
Rationale: The patient with a healing leg wound poses the least infection risk to an immunosuppressed patient who had a liver transplant. Chronic pancreatitis can lead to complications such as infections that can pose a risk to immunosuppressed individuals. Patients infected with respiratory viruses or urinary tract infections are actively infectious, which can put immunosuppressed patients at a higher risk of acquiring infections. Therefore, the patient with a healing leg wound is the least likely to pose an immediate infection risk.
Why is it important to genotype HCV before initiating drug therapy?
- A. Side effects of nucleotide analogs
- B. Measures for improving the appetite
- C. Ways to increase activity and exercise
- D. Administering alpha-interferon (Intron A)
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.
A 49-year-old female patient with cirrhosis and esophageal varices has a new prescription for propranolol (Inderal). Which finding is the best indicator that the medication has been effective?
- A. The patient reports no chest pain.
- B. Blood pressure is 140/90 mm Hg
- C. Stools test negative for occult blood.
- D. The apical pulse rate is 68 beats/minute.
Correct Answer: C
Rationale: The best indicator that propranolol has been effective in a patient with cirrhosis and esophageal varices is when the stools test negative for occult blood. Propranolol is prescribed to decrease the risk of bleeding from esophageal varices. This medication's effectiveness is primarily assessed by the absence of blood in the stools, indicating a reduction in the risk of bleeding from the varices. Monitoring for chest pain, blood pressure control, and a decrease in heart rate are important parameters in other conditions treated with propranolol, such as hypertension, angina, and tachycardia, but in this particular case, the absence of occult blood in the stools is the most relevant indicator of treatment success.
A 30-year-old man is being admitted to the hospital for elective knee surgery. Which assessment finding is most important to report to the healthcare provider?
- A. Tympany on percussion of the abdomen
- B. Liver edge 3 cm below the costal margin
- C. Bowel sounds of 20/minute in each quadrant
- D. Aortic pulsations visible in the epigastric area
Correct Answer: B
Rationale: The correct answer is 'Liver edge 3 cm below the costal margin.' Normally, the lower border of the liver is not palpable below the ribs, so this finding suggests hepatomegaly, which could indicate an underlying health issue. Tympany on percussion of the abdomen, bowel sounds of 20/minute in each quadrant, and aortic pulsations visible in the epigastric area are all within normal limits for a physical assessment and do not require immediate reporting to the healthcare provider.
