A nurse is reviewing a client's medical record and determines that the client has naturally acquired active immunity.
Which of the following would most likely apply?
The client who is exposed to chickenpox for the first time and has no immunity to the disease.
Administration of the varicella vaccine to an individual who has no immunity to the disease.
Administration of the influenza vaccine to an individual who has no immunity to the disease.
Administration of the rubella vaccine to an individual who has no immunity to the disease.
The Correct Answer is A
Choice A rationale:
Naturally acquired active immunity occurs when an individual is exposed to a disease-causing agent for the first time and develops immunity through their immune response. In this case, the client is exposed to chickenpox for the first time, and the immune system will produce antibodies to provide future protection.
Choice B rationale:
Administration of a vaccine (varicella vaccine) is an example of artificially acquired active immunity. The client's immune system responds to the weakened or inactivated pathogen in the vaccine to produce immunity. This choice does not represent naturally acquired immunity.
Choice C rationale:
Similar to choice B, administration of the influenza vaccine is an example of artificially acquired active immunity. The vaccine contains inactivated influenza virus components, prompting the individual's immune system to develop immunity.
Choice D rationale:
Administration of the rubella vaccine is another example of artificially acquired active immunity. The vaccine stimulates the immune system to produce antibodies against rubella, but this is not an example of naturally acquired immunity.

Correct Answer is D
Explanation
Choice A rationale:
Nonprotease inhibitors are not typically a part of HAART (Highly Active Antiretroviral Therapy). Protease inhibitors are used to inhibit HIV replication.
Choice B rationale:
Nonnucleoside reverse transcriptase inhibitors (NNRTIs) are often used in HAART, but they are not the primary agents responsible for inhibiting the integration of the viral genome into the host cell's DNA. NNRTIs target the reverse transcriptase enzyme.
Choice C rationale:
Entry inhibitors are another class of antiretroviral drugs, but they work by blocking the entry of the virus into host cells, not by inhibiting integration. They are used in combination with other drugs in specific cases.
Choice D rationale:
Integrase inhibitors are a class of antiretroviral drugs that specifically target the enzyme integrase, which is responsible for integrating the viral genome into the host cell's DNA. This choice is correct because integrase inhibitors are a crucial component of HAART and help prevent the virus from replicating in the host's cells.
Correct Answer is D
Explanation
Choice A rationale:
Drowsiness is not a common adverse reaction to cephalosporin antibiotics. It is more likely to be associated with medications that have sedative effects.
Choice B rationale:
Headache is a possible adverse reaction to cephalosporins, but it is not a common or specific symptom that the patient needs to report. Headaches are a relatively mild and self-limiting side effect.
Choice C rationale:
Constipation is not a typical adverse reaction to cephalosporin therapy. Gastrointestinal side effects associated with these antibiotics are more commonly diarrhea or nausea. Hypertension (Choice D) is a potential adverse reaction to cephalosporin antibiotics, particularly in patients who are sensitive to changes in blood pressure. It's important for the patient to recognize this symptom and report it promptly, as uncontrolled hypertension can lead to serious health problems. .
