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: At the same laboratory at approximately the same time of day whenever possible. This is important for accurate comparison of CD4+ counts over time. Different labs or varying times can lead to inconsistent results. Choice B is incorrect as fasting is not necessary for CD4+ count testing. Choice C is incorrect because CD4+ count testing should be done before taking antiretroviral medications. Choice D is incorrect as consistency in time and lab location is crucial for reliable CD4+ count monitoring.
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: Correct Answer: B Rationale: 1. Continuing all other drugs as prescribed ensures optimal management of her underlying health condition during pregnancy. 2. Abruptly discontinuing other medications could lead to worsening of her condition or potential risks to the fetus. 3. Stopping belatacept immediately is not recommended as the patient has already made an informed decision to continue it. 4. Consulting with a genetic counselor may be beneficial but is not directly related to the immediate need of managing her medications 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 varicella vaccine to a pregnant woman can pose serious risks to the fetus, including birth defects. This finding has the greatest implication for care as it involves the safety and well-being of both the woman and the unborn child. A: Fear of needles is a common issue that can be managed with appropriate support and techniques. B: Allergy to eggs is a contraindication for receiving the varicella vaccine, but alternative vaccines can be considered. C: Past history of leukemia as a child may affect the immune response to the vaccine, but it is not as critical as pregnancy in this scenario.
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 is crucial for immunocompromised children to ensure the vaccine is appropriate and safe. For an immunocompromised child, certain live vaccines may be contraindicated due to the risk of causing severe infections. Option B is not as critical as the type of vaccine. Option C, while important, does not address the specific safety concerns for an immunocompromised child. Option D is also important but does not directly impact the safety of the upcoming vaccination. Therefore, understanding the type of vaccine is the most crucial information before administering it to 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 pregnant patient. Pregnant individuals are recommended to receive the influenza vaccine to protect both themselves and their unborn child. Pregnant women are at higher risk of complications from the flu. Choice A is incorrect because caregivers of immunocompromised individuals are not in the high-risk group for influenza. Choice C is incorrect because there are egg-free influenza vaccine options available for patients with egg allergies. Choice D is incorrect because the influenza vaccine is not recommended for children under 6 months, and 18 months old is below the recommended age for vaccination.
