Tuberculosis Flashcards
Tuberculosis is a bacterial or viral infection?
Bacterial caused by mycobacterium tuberculosis bacteria.
Tuberculosis is acid-fast and it stains bright ???? with the acid-fast staining smear.
Red
Tuberculosis is an AEROBIC bacteria (so it LOVES ???? and must have it to grow)
Oxygen
Tuberculosis affects mainly the lungs BUT it can also affect the kidneys, brain, spine, joints, and liver.
True or False
True
???? precautions are required when caring for a patient with an active TB infection….wear a ???? at all times when providing patient care and keep the patient located in a special ventilation/negative pressure air room.
Airborne, respirator
The BCG (bacilli Calmette-Guerin) vaccine will give a ???? PPD skin test so a blood test and ???? X-ray is ordered instead.
False positive, chest x-ray
In a Latent tuberculosis infection (LTBI), the mycobacterium tuberculosis bacteria is lying dormant and being controlled by the immune system.
True or a False
True
True or False: Tuberculosis is a contagious bacterial infection caused by mycobacterium tuberculosis and it only affects the lungs.
True
False
Answer: FALSE….tuberculosis is a contagious bacterial infection caused by mycobacterium tuberculosis that affects the lungs AND other systems of the body like the joints, kidneys, brain, spine, liver etc.
A 55-year old male patient is admitted with an active tuberculosis infection. The nurse will place the patient in \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ precautions and will always wear \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ when providing patient care? A. droplet, respirator B. airborne, respirator C. contact and airborne, surgical mask D. droplet, surgical mask
The answer is B. A patient with ACTIVE TB is contagious. The bacterium, mycobacterium tuberculosis which causes TB, is so small that it can stay suspended in the air for hours to days. Therefore, the nurse will place the patient in AIRBORNE precautions. In addition, a special mask must be worn called a respirator (also referred to as an N95 mask…..a surgical mask does NOT work with this condition).
Which statement is correct regarding mycobacterium tuberculosis?
A. This bacterium is an anaerobic type of bacteria.
B. It is an alkali bacterium that stains bright red during an acid-fast smear test.
C. It is known as being an aerobic type of bacteria.
D. It’s an acid-fact bacterium that stains bright green during an acid-fast smear test.
The answer is C. Mycobacterium tuberculosis is AEROBIC (it thrives in conditions that are high in oxygen), and it is an ACID-FAST bacterium, which means when it is stained during an acid-fast smear it will turn BRIGHT RED.
Your patient with a diagnosis of latent tuberculosis infection needs a bronchoscopy. During transport to endoscopy, the patient will need to wear? A. N95 mask B. Surgical mask C. No special PPE is needed D. Face mask with shield
The answer is C. Patients with a latent tuberculosis infection are NOT contagious. Therefore, no special PPE is needed for the patient during transport. HOWEVER, if the patient had ACTIVE tuberculosis they would need to wear a surgical mask during transport.
You are assessing your newly admitted patients who are all presenting with atypical signs and symptoms of a possible lung infection. The physician suspects tuberculosis. So, therefore, the patients are being monitored and tested for the disease. Select all the risk factors below that increases a patient’s risk for developing tuberculosis: A. Diabetes B. Liver failure C. Long-term care resident D. Inmate E. IV drug user F. HIV G. U.S. resident
The answers are C, D, E, and F. Remember from our lecture we discussed the risk factors for developing TB and to remember them I said remember the mnemonic “TB Risk”. It stands for tight living quarters (LTC resident, prison, homeless shelter etc.), below or at the poverty line (homeless), refugee (especially in high risk countries), immune system issue such as HIV, substance abusers (IV drugs or alcohol), Kids less than the age of 5….all these are risk factors.
A 52-year old female patient is receiving medical treatment for a possible tuberculosis infection. The patient is a U.S. resident but grew-up in a foreign country. She reports that as a child she received the BCG vaccine (bacille Calmette-Guerin vaccine). Which physician’s order below would require the nurse to ask the doctor for an order clarification? A. PPD (Mantoux test) B. Chest X-ray C. QuantiFERON-TB Gold (QFT) D. Sputum culture
The answer is A. Patients who have received the BCG vaccine will have a false positive on a PPD (Mantoux test), which is the tuberculin skin test. The BCG vaccine is a vaccine to prevent TB. It is given in foreign countries to children to prevent TB. Therefore, the person has already been exposed to the bacteria via vaccine and will have a false positive. A QuantiFERON-TB Gold test is a better option for this patient. It is a blood test.
You’re teaching a group of long-term care health givers about the signs and symptoms of tuberculosis. What signs and symptoms will you include in your education? A. Cough for a minimum of 6 weeks B. Night sweats C. Weight gain D. Hemoptysis E. Chills F. Fever G. Chest pain
The answers are B, D, E, F, and G. Option A is wrong because a cough should be present for 3 weeks or more (NOT 6 weeks). Option C is wrong because the patient will experience weight LOSS (not gain).
A patient has a positive PPD skin test that shows an 8 mm induration. As the nurse you know that:
A. The patient will need to immediately be placed in droplet precautions and started on a medication regime.
B. The patient will need a chest x-ray and sputum culture to confirm the test results before treatment is provided.
C. The patient will need an IGRA test to help differentiate between a latent tuberculosis infection versus an active tuberculosis infection.
D. The patient will need to repeat the skin test in 48-72 hours to confirm the results.
The answer is B. A positive PPD result does NOT necessarily mean the patient has an active infection of TB. The patient will need a chest x-ray and sputum culture to determine if mycobacterium tuberculosis is present and then treatment will be based on those results. The IGRA test does NOT differentiate between LTBI or an active TB infection. Patients are placed in airborne precautions (NOT droplet) if they have ACTIVE TB.
