foundations of nursing practice questions Questions
Question 1 of 5
A patient was tested for HIV using enzyme immunoassay (EIA) and results were positive. The nurse should expect the primary care provider to order what test to confirm the EIA test results?
Correct Answer: C
Rationale: The correct answer is C: Western blot test. The Western blot test is considered the gold standard for confirming HIV diagnosis after a positive EIA result. It detects specific antibodies to HIV proteins, providing a more accurate confirmation. Other choices are incorrect because: A: Another EIA test would yield the same result as the initial EIA test. B: Viral load test measures the amount of virus in the blood and is not used to confirm HIV diagnosis. D: CD4/CD8 ratio is used to monitor immune status but not to confirm HIV diagnosis.
Question 2 of 5
A patient is beginning an antiretroviral drug regimen shortly after being diagnosed with HIV. What nursing action is most likely to increase the likelihood of successful therapy?
Correct Answer: B
Rationale: The correct answer is B: Addressing possible barriers to adherence. This is crucial because adherence to the antiretroviral drug regimen is key for successful therapy in HIV patients. By identifying and addressing barriers such as medication side effects, cost, or forgetfulness, nurses can help patients stay on track with their treatment. Other choices are incorrect: A: Promoting complementary therapies is not the priority in initiating antiretroviral therapy. Adherence to the prescribed regimen is more critical. C: Educating about the pathophysiology of HIV is important, but it may not directly impact the success of the therapy as much as addressing adherence barriers. D: While follow-up blood work is necessary, it is not as immediate and impactful as addressing adherence barriers at the beginning of therapy.
Question 3 of 5
A hospital nurse has experienced percutaneous exposure to an HIV-positive patients blood as a result of a needlestick injury. The nurse has informed the supervisor and identified the patient. What action should the nurse take next?
Correct Answer: B
Rationale: The correct answer is B: Report to the emergency department or employee health department. 1. Immediate action is crucial after exposure to HIV-positive blood. 2. Reporting to the emergency department or employee health department ensures prompt evaluation and appropriate management. 3. The supervisor should also be informed to initiate the necessary protocols. 4. The other choices are incorrect: - A: Chlorhexidine may not be sufficient for post-exposure prophylaxis. - C: Hydrocolloid dressing is not appropriate for managing needlestick injuries. - D: Following up with the primary care provider may cause delays in receiving timely post-exposure prophylaxis.
Question 4 of 5
A patient with a family history of allergies has suffered an allergic response based on a genetic predisposition. This atopic response is usually mediated by what immunoglobulin?
Correct Answer: D
Rationale: The correct answer is D: Immunoglobulin E. The atopic response in allergies is mainly mediated by IgE antibodies. IgE binds to allergens and triggers the release of histamine and other chemicals that cause allergic symptoms. IgA is mainly found in mucosal areas, IgM is involved in early immune responses, and IgG is important for long-term immunity. IgE is specifically associated with allergic reactions due to its role in sensitizing mast cells and basophils to allergens.
Question 5 of 5
The nurse is providing care for a patient who has experienced a type I hypersensitivity reaction. What condition is an example of such a reaction?
Correct Answer: A
Rationale: The correct answer is A: Anaphylactic reaction after a bee sting. Type I hypersensitivity reactions involve an immediate response triggered by exposure to an allergen, leading to the release of histamine and other inflammatory mediators. In this case, a bee sting would introduce an allergen, causing a rapid and severe systemic reaction, known as anaphylaxis. B: Skin reaction resulting from adhesive tape is an example of a Type IV hypersensitivity reaction, mediated by T cells, not IgE antibodies as in Type I reactions. C: Myasthenia gravis is an autoimmune disorder involving antibodies attacking acetylcholine receptors, not a Type I hypersensitivity reaction. D: Rheumatoid arthritis is an autoimmune disorder involving immune complexes and inflammatory responses, not a Type I hypersensitivity reaction.
