Q

A

Immune competence

76
Q

Abnormal responses of the immune system are typically the result of an infection, medical therapy, or exposure to select toxins. These abnormal responses are divided into two basic categories:

A

Immune deficiency disorders & autoimmune diseases

77
Q

an insufficient production of antibodies, immune cells, or both; the disorders may be congenital or acquired. A deficiency in the immune system leaves the body unable to resist foreign microbes or toxins. Common viral infections, such as influenza or infectious mononucleosis, can cause a short-term weakened immune response.

A

Immune deficiency disorders

78
Q

the immune system is unable to tell the difference between “self” (the body’s own cells) and “nonself” (foreign cells).

Body attacks self.

A

Autoimmune disorders

79
Q

A

Anasaca ( waisting syndrome)

85
Q

defined as losing more than 10% of weight along with at least 30 days of either diarrhea or weakness accompanied by fever. There is loss of 226body fat and muscle mass. This syndrome has a strong correlation to progression of AIDS and typically leads to death. Contributing factors include decreased appetite, the inability to absorb nutrients through the small intestines because of diarrhea, and an altered metabolism that may be associated with hormone levels.

A

Waisting Syndrome

86
Q

tumors of the tissues and cells of the lymphatic system. Non-Hodgkin lymphoma (NHL) is the most common lymphoma in people with HIV/AIDS. Most cases of NHL in these patients are large B-cell lymphomas and have an approximate 2-year mortality rate. HAART therapy appears to slow its progression; however, death is the outcome in a large percentage of cases

A

Lymphomas

87
Q

The lymphatic system drains water, proteins, lipids, and waste from the interstitial spaces throughout the entire body and returns them to the lymph nodes, where waste materials and foreign cells, such as bacteria, are filtered out. Once “clean,” the lymph fluid returns to the lymphatic vessels, and the whole process is repeated. When the lymph system is unable to circulate normally, large amounts of fluid accumulate (lymphedema), causing swelling. If not controlled, this swelling can lead to further damage to surrounding nerves, blood vessels, and tissues.

A

Lymphedema

88
Q

Inherited or acquired

A

2 types of Lymphedemia

89
Q

inherited form (primary) is a congenital condition in which there is deficient growth of the lymphatic system, especially in a lower extremity. This condition chiefly affects women and most often becomes apparent during the middle teens to early twenties.

A

Inherited lymphedema

90
Q

secondary) typically results from an obstruction caused by trauma to the lymph vessels and nodes, such as occurs during mastectomy when lymph nodes are removed, after radiation therapy, or after a liposuction procedure where some of the lymph nodes may have been damaged. Other causes of obstruction include extensive soft-tissue injury and scar formation and, in tropical countries, parasites that enter lymph channels and block them

A

Acquired lymphedema

91
Q
  • Chronic muscle pain, spasms, or tightness
  • Stiffness on waking or after staying in one position for too long
  • Moderate to severe fatigue and decreased energy levels
  • Reduced exercise tolerance and increased muscle pain after exercise
  • Tension or migraine headaches
  • Jaw and facial tenderness
  • Insomnia or waking up feeling just as tired as when you went to sleep
  • Anxiety, depression
  • Difficulty with concentration, memory recall, and performing simple mental tasks
  • Abdominal pain, bloating, nausea, and constipation alternating with diarrhea (irritable bowel syndrome)
  • A sensation of swelling (without actual swelling) in the hands and feet
  • Increase in urinary urgency or frequency (irritable bladder)
  • Sensitivity to one or more of the following: odors, noise, bright lights, medications, certain foods, and cold
A

S/S of Fibromyalgia

92
Q

A condition of chronic systemic pain and multiple symptoms that could not be explained as caused by any other source or disease. This disorder affects 5 million people in the United States. Women are 10 times more likely than men to experience fibromyalgia symptoms, and the condition is typically seen in women ranging in age from 25 to 60 years.

A

Fibromyalgia

93
Q

may also be caused by a deficiency in the neurotransmitters dependent on serotonin and norepinephrine within the central nervous system.

symptoms have been present for at least 3 months; whether they occur on both sides of the body; and whether there are any tender points in at least 11 of 18 sites. Other symptom diagnostic criteria are sleep problems, poor cognition, fatigue, headaches, depression, and abdominal pain

A

Allodynia

95
Q

An abnormal response to certain substances; it is considered a systemic immune disorder, rather than a localized one, and the reaction can be seen or expressed in one or more body systems

A

Allergy

96
Q

A side effect of medical treatment

A

Iatrogenic

97
Q

Extreme allergic reaction that is life-threatening

A

Anaphylaxis

98
Q

1.HIV attaches to CD4 receptor or T helper cell
2 Infected cells replicates itself millions of times.
3.T helper cells fail to activate phagocytosis.
4. Immune system is unable to respond effectively.
5. OI occurs

A

HIV Invasion Steps

99
Q

The most effective current treatment is highly active antiretroviral therapy (HAART), a combination of available drugs recommended for HIV. This therapy is also effective against other conditions common to HIV/AIDS. OIs are treated with drugs specific to their cause, and sometimes antimicrobials are given to prevent infection.

A

Avoid direct sunlight and any other type of ultraviolet lighting, including tanning beds.
• Use an SPF 30 or higher sunblock when outdoors.
• Wear long pants, a long-sleeved shirt, and a wide-brimmed hat when in the sun.
• Cleanse the skin only with a mild soap that has a glycerin base.
• Dry the skin thoroughly by patting rather than rubbing it.
• Apply nonperfumed lotion liberally to dry skin areas at least twice a day.
• Avoid using alcohol-based skin care products, face powder, or other astringent agents.
