4 Body Systems and Related Conditions

Transparency 4-1: The Integumentary System

4


1. Describe the integumentary system

Remember the following points about the integumentary system:

• Largest organ and system

• Natural protective covering

• Prevents excessive loss of water and injury to internal organs

• Skin made of tissue and glands

• Skin is a sense organ

• Regulates body temperature (Dilates if hot, which allows more blood to surface for sweat/evaporation. Constricts if cold to keep in body heat.)

4



Normal changes of aging include the following:

• Skin gets thinner and more fragile.

• Skin is drier and less elastic.

• Protective fatty tissue gets thinner and person may feel colder.

• Hair thins and turns gray.

• Wrinkles and brown spots appear.

• Fingernails and toenails thicken and become more brittle.

• Reduced circulation can cause skin dryness, itching, and irritation.

4

Handout 4-1: Sexually Transmitted Diseases and Infections

Sexually transmitted diseases (STDs), also called venereal diseases, are diseases passed through sexual contact with an infected person. This contact includes sexual intercourse, contact of the mouth with the genitals or anus, and contact of the hands to the genitals. A person may be infected, and may potentially infect others, without showing signs of the disease. This is called a sexually transmitted infection (STI).

Using latex condoms during sexual contact can reduce the chances of being infected with or passing on some STDs and

STIs. The human immunodeficiency virus (HIV), acquired immune deficiency syndrome (AIDS), and some kinds of hepatitis can be sexually transmitted. STDs are very common. They can cause serious health problems. Residents may be unaware of or embarrassed by symptoms of an STD. Be professional when dealing with STDs and STIs. This can help put residents at ease.


Handout 41: Sexually Transmitted Diseases and Infections (cont’d.)

Chlamydia infection is caused by organisms in the mucous membranes of the reproductive tract. Chlamydia can cause serious infection, including pelvic inflammatory disease (PID) in women. PID can cause sterility. Signs of chlamydia infection are yellow or white discharge from the penis or vagina and burning with urination. It is treated with antibiotics.

Syphilis can be treated effectively in the early stages, but if left untreated, it can cause brain damage, mental illness, and even death. Babies born to mothers with syphilis may be born blind or with other serious birth defects. Syphilis is easier to detect in men than in women. This is due to open sores called chancres that form on the penis soon after infection.



The chancres are painless and can go unnoticed. If untreated, the infection spreads to the heart, brain, and other vital organs.

Common symptoms at this stage include rash, sore throat, or fever. When detected, syphilis can be treated with penicillin or other antibiotics. The sooner it is treated, the better the chances of preventing long-term damage and avoiding infection of others.

Gonorrhea, like syphilis, can be treated with antibiotics and is easier to detect in men than in women. If untreated, gonorrhea can cause sterility in both men and women. Most women with gonorrhea show no early symptoms. This makes it easy for women to spread the disease. Men with gonorrhea will often show a greenish or yellowish discharge from the penis within a week after infection. Burning with urination is another common symptom in men.



Herpes simplex 2, unlike the other STDs discussed here, is caused by a virus. It cannot be treated with antibiotics. Once infected with the herpes virus, a person cannot be cured. The person may have repeated outbreaks of the disease for the rest of his or her life. A herpes outbreak includes burning, painful, red sores on the genitals. These heal in about two weeks. The sores are infectious, but a person with herpes virus can also spread the infection when sores are not present.

Some people infected with herpes never have repeated outbreaks. The later episodes may not be as painful as the first outbreak. Antiviral drugs can help people stay symptom-free longer. Babies born to women infected with herpes simplex 2 can be infected during birth. Pregnant women experiencing a herpes outbreak are usually delivered by cesarean section, or C-section.

Define the following term:

Lymph

A clear yellowish fluid that carries disease-fighting cells called lymphocytes.


Transparency 4-27: The Lymphatic System

10. Describe the immune and lymphatic systems and related conditions

Remember the following points about the lymphatic system:

• Function of system is to remove excess fluids and waste products as well as to help the immune system to fight infections.

• It is closely related to the circulatory system because lymph fluid, after being purified in the lymph nodes, flows into the bloodstream.

• It has no pump, but is circulated by muscle activity, massage, and breathing.

• Nonspecific immunity protects the body from disease in general. Specific immunity protects against a particular disease that is invading the body at a given time.

4



Normal changes of aging to the immune and lymphatic systems include the following:

• Increased risk of infections due to weaker immune system

• Decreased response to vaccines

4




How can you help residents with the normal changes of aging to the lymphatic and immune systems?

4



Observe and report the following regarding the immune and lymphatic systems:

• Recurrent infections

• Swelling of lymph nodes

• Increased fatigue

4



HIV/AIDS affects the immune and lymphatic systems:

• Acquired immunodeficiency syndrome (AIDS) is caused by

HIV (human immunodeficiency virus).

• HIV attacks the immune system and disables it.

• HIV is transmitted by sexual contact, blood, infected needles, or from mother to fetus.

• Symptoms at transmission are like flu.

• Later symptoms include infections, tumors, and central nervous system symptoms.

• Late stage is AIDS dementia complex.

4



Signs and symptoms of HIV/AIDS include the following:

• Appetite loss

• Involuntary weight loss

• Flu-like symptoms

• Night sweats

• Swollen lymph nodes

• Severe diarrhea

• Dry cough

• Skin rashes

4



Signs and symptoms of HIV/AIDS (cont’d.):

• Painful white spots in mouth

• Cold sores

• Warts on the skin and in mouth

• Inflamed and bleeding gums

• Low resistance to infection

• Bruising that does not go away

• Kaposiís sarcoma

• AIDS dementia complex

4



REMEMBER:

• Opportunistic infections invade the weakened body of a resident with AIDS.

• Treatment is medication.

• Drugs slow the progress but there is no cure for the disease.


Handout 4-2: Myths About HIV and AIDS

Myth: If I am HIV positive, that means I have AIDS.

Fact: HIV positive means that your body was exposed to the virus. Since your body was exposed, there is a good chance that you are infected with the virus. But it does not mean that you have AIDS. AIDS develops over time.

Myth: HIV is the same as AIDS.

Fact: HIV is the virus that causes AIDS. AIDS is a group of symptoms that develop during the last stage of HIV infection.


Handout 4-2: Myths About HIV and AIDS

Myth: I can get HIV from an infected person by shaking hands, hugging, or kissing.

Fact: HIV is not spread through casual contact. There is a slight possibility that you could become HIV infected through kissing if you and the infected person both have open bleeding sores in your mouths and the infected person’s blood gets into yours. If you are really worried about this, do an oral exam on your partner before kissing him or her.

Myth: I can get HIV from telephones.

Fact: The HIV virus can't live outside of the body. You cannot become infected through saliva.

Myth: I can get HIV from doorknobs, tables, chairs, or push buttons.

Fact: The HIV virus can't live outside of the body.


Handout 42: Myths About HIV and AIDS (cont’d.)

Myth: I can get HIV from eating food that was prepared by an infected person.

Fact: Once again, HIV dies very quickly outside the body. Even if the food prep person cut his finger and then attractively arranged your food on your plate, you would not become infected from eating this food. Once any body fluid is dry, you can be absolutely sure that the virus is dead. Just about the only way you could become infected this way is if the food prep person cuts off a finger, and as he is bleeding in your food, you are eating it at that exact moment. This scenario is rather extreme.



Myth: I can get HIV from toilets.

Fact: Toilets have been blamed for just about everything, from getting you pregnant to giving you sexually transmitted diseases

(STD). The only way you might possibly become HIV infected from a toilet seat is to have unprotected sex while sitting on it!

Myth: I can get HIV from mosquitoes.

Fact: Although it sounds very possible, you cannot become HIV infected through mosquitoes, fleas, ticks, or lice. For this to happen, the HIV would have to survive in the insect saliva and salivary glands. HIV is a human virus and cannot survive outside of the human body. As a result, HIV will not and does not survive in mosquitoes, fleas, ticks, or lice. If this were a route of transmission, we would all have been infected a very long time ago.



Myth: I can get HIV from breathing the same air as an infected person.

Fact: HIV does not spread through the air. You cannot get HIV by being in the same room with someone who is infected with the virus.


Transparency 4-28: Care Guidelines for HIV/AIDS

• Wash hands often. Follow Standard Precautions, and keep everything clean.

• High-protein, high-calorie, high-nutrient meals can help maintain healthy weight.

• Help make mealtimes pleasant and relaxing. Know residents’ favorite foods. Notify nurse of appetite loss/difficulty eating.

• If residents have infections in the mouth they may need food that is low in acid/spice and neither cold nor hot. Good mouth care is vital.

• Small, frequent meals can help with nausea. Help ensure adequate fluid intake.


Transparency 428: Care Guidelines for HIV/AIDS (cont’d.)

• If diarrhea is severe, doctor may order “BRAT” diet

(bananas, rice, apples, toast). This is helpful short-term.

• Good rehydration fluids include water, juice, soda and broth. Avoid caffeinated beverages.

• Numbness, tingling, and pain in the feet and legs is usually treated with medications. Going barefoot or wearing loose, soft slippers may help. Bed cradle may be used.

• Treat residents with respect and provide emotional support.

• Provide safe environment and close supervision in ADLs.
