Immune System Drugs Questions
Question 1 of 5
The nurse advises human immunodeficiency virus (HIV)-positive patients about blood draws to obtain a CD4+ count. What is the correct information to give them about when and how this laboratory blood work should be done?
Correct Answer: A
Rationale: The correct answer is A because obtaining CD4+ counts at the same laboratory and around the same time of day whenever possible ensures consistency in results. This consistency is important for tracking disease progression and treatment efficacy. Choice B, fasting, is irrelevant to CD4+ counts. Choice C, after taking antiretroviral medications, may affect the results due to potential drug interference. Choice D, any laboratory at any time, lacks consistency and may lead to inaccurate comparisons over time. Thus, choice A is the most appropriate for accurate monitoring of HIV-positive patients.
Question 2 of 5
Your patient taking belatacept becomes pregnant. After discussion with her partner, you, and her health care provider, she decides the best thing to do is continue taking the drug while pregnant. In addition to making this informed decision, what else should she do?
Correct Answer: B
Rationale: Step 1: Continuing all other drugs as prescribed ensures that the patient's underlying medical conditions are properly managed during pregnancy. Step 2: Discontinuing other drugs could lead to uncontrolled health issues, posing risks to both the mother and the fetus. Step 3: Stopping belatacept immediately without medical guidance could result in rejection of a transplanted organ. Step 4: Consulting with a genetic counselor is not necessary in this scenario as the primary concern is managing the patient's medical conditions during pregnancy.
Question 3 of 5
The nurse is preparing to administer varicella vaccine to a young woman. Which of the following findings has the greatest implication for this young woman's care?
Correct Answer: D
Rationale: The correct answer is D because administering the varicella vaccine to a pregnant woman can pose risks to both the woman and the fetus. Varicella vaccine is a live attenuated vaccine and is contraindicated during pregnancy due to the potential risk of transmitting the virus to the fetus. This can lead to congenital varicella syndrome, which can cause serious birth defects. Choice A is not the correct answer as fear of needles can be managed with appropriate nursing interventions. Choice B is not the correct answer because while the varicella vaccine is produced in chick embryo cell cultures, the risk of an allergic reaction in someone with a history of egg allergy is low. Choice C is not the correct answer as a history of leukemia as a child is not a contraindication to receiving the varicella vaccine.
Question 4 of 5
The nurse is preparing to administer routine, recommended immunizations to an immunocompromised 1-year-old child. What is the most important information to know before administering a vaccination?
Correct Answer: A
Rationale: The correct answer is A because knowing the type of vaccine to be administered is crucial for an immunocompromised child to assess its safety and efficacy. Different vaccines have varying levels of risk and efficacy for immunocompromised individuals. Choice B is not directly related to the safety or appropriateness of administering the vaccine. Choice C, while important, does not provide immediate information on the specific vaccine being administered. Choice D, although relevant, does not provide information on the specific vaccine's safety for an immunocompromised child.
Question 5 of 5
Which of the following patients would be eligible to receive the influenza vaccine?
Correct Answer: B
Rationale: The correct answer is B, the patient who is pregnant. Pregnant individuals are at higher risk of complications from influenza and are recommended to receive the influenza vaccine to protect themselves and their unborn child. A: The patient taking care of her son with HIV should also receive the influenza vaccine to prevent transmission, but this alone does not make her eligible for the vaccine. C: Patients with egg allergy can receive the influenza vaccine with appropriate precautions, so this does not automatically disqualify them. D: The child who is 18 months old is eligible for the influenza vaccine, but pregnant individuals are at higher risk, hence B is the correct answer.
