A 14-year-old girl requests a vaccination for human papillomavirus. After the nurse administers the first dose, which of the following is important to include in the patient's teaching?

Correct Answer: D

Rationale: The correct answer is D because it is crucial for the patient to understand the importance of completing the full HPV vaccination series for optimal protection. By informing the patient about the date for the next dose, it ensures adherence to the recommended schedule and maximizes the effectiveness of the vaccine. This helps in building long-term immunity against HPV-related diseases. Choice A is incorrect because HPV vaccination does not prevent all sexually transmitted diseases, it specifically targets HPV strains. Choice B is incorrect because even after HPV vaccination, regular Pap smears are still necessary for cervical cancer screening. Choice C is incorrect as mild pain at the injection site is a common side effect of the vaccine and does not typically require notification to the healthcare provider unless it persists or worsens.

Correct Answer: B

Rationale: The correct answer is B: The need to use barrier contraceptives while taking the drug. This is important because immune modulators can have teratogenic effects, meaning they can harm a developing fetus. Using barrier contraceptives can help prevent pregnancy and protect the fetus from potential harm. Choice A is incorrect because continuing oral contraceptives may not provide adequate protection against pregnancy while on immune modulators. Choice C is incorrect as avoiding sexual intercourse is not necessary as long as effective contraception is used. Choice D is incorrect as taking aspirin daily is not related to the use of immune modulators and may not decrease adverse effects.

Correct Answer: A

Rationale: The correct answer is A: Alefacept (Amevive). Alefacept is a biologic drug that specifically targets T-cells, which play a crucial role in the pathogenesis of psoriasis. By suppressing T-cell activity, Alefacept helps to reduce the inflammation and proliferation of skin cells seen in psoriasis. Additionally, Alefacept does not impact B-cell function, making it a suitable choice for this patient. Choice B (Azathioprine) is incorrect because it primarily acts on B-cells and is not as effective in targeting T-cells involved in psoriasis. Choice C (Cyclosporine) is incorrect as it is a calcineurin inhibitor that suppresses T-cell activity but also affects B-cells. Choice D (Glatiramer acetate) is incorrect as it is used to treat multiple sclerosis by modulating the immune response but does not specifically target T-cells involved in psoriasis.

Correct Answer: A

Rationale: The correct answer is A: To avoid crowds. Interferon alfa 2b can weaken the immune system, making the patient more susceptible to infections. Avoiding crowds helps reduce the risk of exposure to pathogens. B, increasing salt intake, is incorrect as it is not a recommended action for patients taking interferon alfa 2b. C, decreasing milk intake, is also incorrect as there is no evidence to suggest that milk consumption interferes with the effectiveness of this medication. D, eating three meals a day, is irrelevant to the action needed to manage the side effects of interferon alfa 2b.

Correct Answer: D

Rationale: Interferons are proteins released by cells in response to viral infections. Choice D is correct because interferons interfere with viral replication within infected cells by activating antiviral proteins. Choices A, B, and C are incorrect because interferons do not stimulate B-lymphocyte activity, interfere with stem cell multiplication, or stimulate growth and differentiation of lymphocytes. Interferons primarily function as part of the innate immune response to combat viral infections.
