<u>Complete Question:</u>

A nurse is caring for a 26-year-old client recently diagnosed with human immunodeficiency virus (HIV) and has a CD4 count of 150. The client needs an update on immunizations and asks which ones are needed. Which vaccines are required to comply with the recommended immunization schedule for a client with HIV?

a. Influenza; measles, mumps, rubella (MMR); varicella; and hepatitis A vaccines .

b. Pneumococcal, MMR, influenza, and varicella vaccines .

c. Diphtheria, tetanus, hepatitis A, and hepatitis C vaccines .

d. Tetanus, hepatitis B, influenza, and pneumococcal vaccines.

<u>Correct Option:</u>

Tetanus, hepatitis B, influenza, and pneumococcal vaccines are required to comply with the recommended immunization schedule for a client with HIV.

<u>Option: D</u>

<u>Explanation:</u>

Human immunodeficiency virus (HIV) is responsible for killing the WBC (white blood cells) that battle infection, as this virus destroys the immune system, which can follow certain cancers.
While AIDS (acquired immune deficiency syndrome) is the last stage of HIV infection.
In contrast to influenza vaccine delivery that avoids both viral and bacterial pneumonia, Streptococcus pneumoniae vaccination is suggested. The risk of invasive pneumococcal illness is strong for HIV-infected people.
HIV patients obviously recover from influenza vaccination, the reaction of antibodies to seasonal flu vaccination is usually lower than among HIV-uninfected people.
