Nokea
The nurse is caring for a patient whose HIV status is unknown. Which of these patient exposures is most likely to require postexposure prophylaxis for the nurse?
- A. Needle stick with a needle and syringe used to draw blood
- B. Splash into the eyes when emptying a bedpan containing stool
- C. Contamination of open skin lesions with patient vaginal secretions
- D. Needle stick injury with a suture needle during a surgical procedure
Correct Answer: A
Rationale: Puncture wounds are the most common means for workplace transmission of bloodborne diseases, and a needle with a hollow bore that had been contaminated with the patient's blood would be a high-risk situation. The other situations described would be much less likely to result in transmission of the virus.

When assessing an individual who has been diagnosed with early persistent HIV infection and has a normal CD4 count, which of the following assessments should the nurse conduct?
- A. Check neurological orientation.
- B. Ask about problems with diarrhea.
- C. Palpate the regional lymph nodes.
- D. Examine the oral mucosa for lesions.
Correct Answer: C
Rationale: Persistent generalized lymphadenopathy is common in the early stage of persistent infection. Diarrhea, oral lesions, and neurological abnormalities would occur in the later stages of HIV infection.
Which information about an HIV-positive patient who is taking antiretroviral medications is most important for the nurse to address when planning care?
- A. The patient's blood glucose level is 6.9 mmol/L.
- B. The patient complains of feeling 'constantly tired.'
- C. The patient is unable to state the adverse effects of the medications.
- D. The patient states 'sometimes I miss a dose of zidovudine (AZT).'
Correct Answer: D
Rationale: Since missing doses of ART can lead to drug resistance, this patient statement indicates the need for interventions such as teaching or changes in the drug scheduling. Elevated blood glucose and fatigue are common adverse effects of ART. The nurse should discuss medication adverse effects with the patient, but this is not as important as addressing the skipped doses of AZT.
After having a positive rapid-antibody test for HIV, a patient is anxious and does not appear to hear what the nurse is saying. Which of the following actions should the nurse implement?
- A. Teach the patient about the medications available for treatment.
- B. Inform the patient how to protect sexual and needle-sharing partners.
- C. Remind the patient about the need to return for retesting to verify the results.
- D. Ask the patient to notify individuals who have had risky contact with the patient.
Correct Answer: C
Rationale: After an initial positive antibody test, the next step is retesting to confirm the results. A patient who is anxious is not likely to be able to take in new information or be willing to disclose information about HIV status of other individuals.
A patient who has vague symptoms of fatigue and headaches is found to have a positive enzyme immunoassay (EIA) for human immunodeficiency virus (HIV) antibodies. In providing health teaching, which of the following information should the nurse include?
- A. The EIA test will need to be repeated to verify the results.
- B. A viral culture will be done to determine the progress of the disease.
- C. It will probably be 10 or more years before the patient develops acquired immunodeficiency syndrome (AIDS).
- D. The Western blot test will be done to determine whether AIDS has developed.
Correct Answer: A
Rationale: After an initial positive EIA test, the EIA is repeated before more specific testing such as the Western blot is done. Viral cultures are not part of HIV testing. Because the nurse does not know how recently the patient was infected, it is not appropriate to predict the time frame for AIDS development. The Western blot tests for HIV antibodies, not for AIDS.
The nurse is caring for a patient who has just been diagnosed with early persistent HIV infection. Which of the following prophylactic measures should the nurse anticipate being included in the plan of care?
- A. Hepatitis B vaccine
- B. Pneumococcal vaccine
- C. Influenza virus vaccine
- D. Trimethoprim-sulfamethoxazole
- E. Varicella-zoster immune globulin
Correct Answer: A,B,C
Rationale: Prevention of other infections is an important intervention in patients who are HIV positive, and these vaccines are recommended as soon as the HIV infection is diagnosed. Antibiotics and immune globulin are used to prevent and treat infections that occur later in the course of the disease, when the CD4 count has dropped or when infection has occurred.
