e-lub [12.9K]

<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.

. Imagine that you are a doctor in a maternity ward. During your last shift, 20 babies were born. 10 had blue eyes, and 10 had b
icang [17]

<u>The</u><u> potential genotypes</u><u> for newborns with brown eyes are</u><u> BB and Bb</u><u>, whereas the potential genotype for newborns with blue eyes is bb.</u>

  • According to the information provided above, b = allele for blue eyes is recessive while B = allele for brown eyes is dominant.
  • A recessive allele is one that cannot express itself in the presence of a dominant allele, while a dominant allele conceals the effect of a recessive allele.
  • A dominant allele expresses itself in the presence of a recessive allele.
  • While a dominant allele can express itself in both a homozygous and heterozygous state, a recessive allele can only do so.
  • Therefore, newborns with brown eyes will have two genotype options: BB and Bb, whereas those with blue eyes will only have one.

VladimirAG [237]

The correct answer is Lysosome.  

A membrane-bound organelle witnessed in various animal cells and the majority of plant cells is known as the lysosome. They are spherical vesicles, which comprises hydrolytic enzymes that can dissociate various types of biomolecules.  

A lysosome exhibits a particular composition, of both its lumenal proteins and membrane proteins. The lysosome functions as the waste disposal system of the cell by digesting undesired substances in the cytoplasm, both from obsolete components within the cell and from external of the cell.
