HIV
Human Immunodifficiency Virus
what specific immune cells does HIV attack? What does it use it for?
CD4+ T-cells
high-jacks the host cell to produce more of itself
HIV binds to CD4+ cells in the host, also known as helper T cells. These cells are responsible for regulating the normal immune response. When the HIV DNA inserts itself into the CD4+ cell, it will cause cell death. This causes the number of CD4+ cells to decrease, therefore weakening the immune system.
AIDS
Acquired Immuno Deficiency Syndrome
When is AIDS diagnosed?
When CD4+ T-cells are less than or equal to 200 cells per uL or when opportunistic infection is diagnosed
AHI
Acute HIV Infection refers to the initial period after infection
at this moment EIA will be negative
After about how many weeks will symptoms appear after infection? And what symptoms appears?
1-4 weeks after infection
Symptoms include fatigue, fever, malaise, headache, muscle aches, rash, sore throat, swollen lymph glands
Whats the normal count for CD4+?
500-1500
How long may take for HIV to appear in tests?
3 - 6 mo
Name the steps for HIV life cycle
- HIV binds the T-cells
- Viral RNA is released into the host cell
- The viral RNA is converted into the viral DNA through a process called reverse transcriptase. During reverse transcriptase, an enzyme reads the sequence of viral DNA nucleic acids that have entered the host cell and transcribes the sequence into a complementary DNA sequence.
- Viral DNA enter the T-call’s nucleus and inserts itself into the T-cell’s DNA
- The T cell starts to make copies of HIV components
- Protease an enzyme helps create new virus particles.
- The new virion ( virus particle) is released from the T cell.
Opportunistic Infections examples
Tuberculosis Recurrent pneumonia Pneumocystis jirovecii pneumonia (aka PCP) Wasting syndrome Candidiasis of trachea, bronchi or lungs
Most common modes of transmission for HIV
Sexual Contact Male-to-male (MSM) Heterosexual Blood Exposure Injecting drug use (IDU) Occupational exposure Organ transplant Blood/blood products transfusion Perinatal Before or during birth Breastfeeding
What are the testings for HIV?
Screening tests
Orasure: detects HIV antibodies in oral fluid
Rapid test: detects HIV antibodies in blood from finger prick
Confirmatory tests
IFA: highly accurate detection of HIV antibodies from venous blood
Western blot: very specific detection of HIV antibodies from venous blood
What is HAART?
Highly Active Anti-Retroviral Treatment (HAART) includes at least 3 drugs. This is to reduce the likelihood of development of drug resistance.
There can be many, tough side effects to the drugs.
Drugs aim to keep the viral load at a minimum.
Stopping treatment often results in a quick jump in viral load.
A preschooler is admitted with a diagnosis of acute glomerulonephritis. The child’s history reveals a 5-lb weight gain in 1 week and periorbital edema. How can the nurse obtain the most accurate information on the status of the child’s edema?
- Weighing daily
- Observing body changes
- Measuring intake and output
- Monitoring electrolyte values
Correct 1. Weight monitoring is the most useful means of assessing fluid balance and changes in the edematous state; 1 L of fluid weighs about 2.2 lb.
2. Visual inspection is subjective and generally inaccurate. 3. Measuring intake and output is not as accurate as daily weights; fluid may be trapped in the third compartment. 4. Monitoring of electrolyte values is unreliable; they may or may not be altered with fluid shifts.
In an interview with a pregnant patient, the nurse discussed the three risk factors that have been cited as having a possible effect on prenatal development. They are:
- Nutrition, stress, and mother’s age.
- Prematurity, stress, and mother’s age.
- Nutrition, mother’s age, and fetal infections.
- Fetal infections, prematurity, and placenta previa.
Answer: 1.
The woman’s diet before and during pregnancy has a significant effect on fetal development; the mother’s age may contribute to a risk for chromosomal defects (older mothers) or the lack of prenatal care (adolescent mothers); pregnancy is often accompanied by stress because of all of the developmental changes, and it is important to know whether or not the mother has an effective support system.
A parent has brought her 6-month-old infant in for a wellchild check. Which of her statements indicates a need for further teaching?
1. “I can start giving her whole milk at about 12 months.”
2. “I can continue to breastfeed for another 6 months.”
3. “I’ve started giving her plenty of fruit juice as a way to
increase her vitamin intake.”
4. “I can start giving her solid food now.”
Answer: 3.
Breast milk or formula is recommended at this time; fruit juice is not considered a nutritive addition.
The type of injury a child is most vulnerable to at a specific age is most closely related to which of the following?
- Provision of adult supervision.
- Educational level of the parent
- Physical health of the child
- Developmental level of the child
Answer: 4.
The child’s cognitive and physical development need to be considered initially when assessing the potential risk for injury.
Which approach would be best for the nurse to use with a hospitalized toddler?
- Always give several choices.
- Set few limits to allow for open expression.
- Use noninvasive methods when possible.
- Gain cooperation before attempting treatment
Answer: 4.
Toddlers are learning to become independent and frequently display negative behavior if an effort to gain their trust is not provided initially. Providing too many choices does not support their efforts to gain control.
The nurse is providing information on prevention of sudden infant death syndrome (SIDS) to the mother of a young infant. Which of the following statements indicates that the mother has a good understanding? (Select all that apply.)
- “I won’t use a pacifier to help my baby sleep.”
- “I’ll be sure my baby does not spend any time on her
abdomen. ” - “I’ll place my baby on her back for sleep.”
- “I’ll be sure to keep my baby’s room cold.”
Answer: 3, 4.
The American Academy of Pediatrics has clearly recommended that infants be placed on their backs for sleep to help prevent SIDS. Keeping the room cool is also important.
In evaluating the gross-motor development of a 5-month-old infant, which of the following would the nurse expect the infant to do?
- Roll from abdomen to back
- Move from prone to sitting unassisted
- Sit upright without support
- Turn completely over
Answer: 1.
The 5-month-old infant should be able to turn from abdomen to back.
Parents are concerned about their toddler’s negativism and ask the nurse for guidance. Which is the most appropriate recommendation?
- Provide more attention.
- Reduce opportunities for a “no” answer.
- Be consistent with punishment.
- Provide opportunities for the toddler to make decisions.
Answer: 2. Giving toddlers realistic choices reduces the opportunity for a negative response and helps support their need for control.
When nurses are communicating with adolescents, they
should:
1. Be alert to clues to their emotional state.
2. Ask closed-ended questions to get straight answers.
3. Avoid looking for meaning behind adolescents’ words or actions.
4. Avoid discussing sensitive issues such sex and drugs.
Answer: 1.
Adolescents are searching for their identity and trying to become emotionally independent from parents while maintaining family ties. Depression, substance abuse, and violence are all real concerns during this period; thus the nurse must be aware of the adolescent’s emotional state.
Which of the following statements is most descriptive of the psychosocial development of school-age children?
- Boys and girls play equally with each other.
- Peer influence is not yet an important factor to the child.
- They like to play games with rigid rules.
- Children frequently have “best friends.”
Answer: 4.
Peer relationships become very important to school-age children, and they usually develop close friendships.
You are caring for a 4-year-old child who is hospitalized for an infection. He tells you that he is sick because he was “bad.” Which is the most correct interpretation of his comment?
- Indicative of extreme stress
- Representative of his cognitive development
- Suggestive of excessive discipline at home
- Indicative of his developing sense of inferiority
Answer: 2.
Preschoolers exhibit “egocentric” thought, meaning that they truly believe that their thinking is shared by others and that they can control their environment by their thoughts.
