Question 1

The nurse is preparing to administer dapsone to a client and knows it is important to monitor which body system for adverse effects when administering this medication?

Accepted Answer

Dapsone can cause hemolytic anemia and methemoglobinemia, which may result in damage to the hematologic system. Therefore, it is important to monitor this system for adverse effects when administering this medication.

Question 2

The nurse is caring for a male client who has been diagnosed with tuberculosis.The client asks when he will be considered noninfectious.The nurse knows that a client will be considered noninfectious when the:

Accepted Answer

A client with tuberculosis is considered noninfectious when the sputum culture and smear are negative, indicating that there is no longer active growth of tubercle bacilli in the client's respiratory secretions. The PPD may remain positive even after treatment, and there is no direct correlation between white blood cell count or chest x-ray findings and infectiousness.

Question 3

The nurse is caring for a client with latent TB.Which circumstances would place this nurse in the high-risk category for the transmission of TB?
Select all that apply.

Accepted Answer

The nurse is at high risk for TB transmission when caring for a client who is HIV-positive, serving a prison sentence, or living with someone with active TB. These individuals are more likely to have active TB, which is the contagious form of the disease. Caring for a client in a pediatric clinic or a pregnant client does not necessarily increase the nurse's risk for TB transmission.

Question 4

The nurse reviewing the medication history of the client taking dapsone would have concern if which drug were listed?

Accepted Answer

St. John's wort is known to decrease the effectiveness of many medications, including dapsone. Therefore, its use should be avoided or closely monitored in clients taking dapsone. Potassium, aspirin, and Viagra do not interact directly with dapsone.

Question 5

The nurse is implementing direct observance therapy (DOT)for a client being treated for tuberculosis in the community.The nursing student asks what this means.The nurse correctly responds by saying:

Accepted Answer

Direct observance therapy (DOT) involves the nurse physically observing the client taking their medication to ensure adherence and prevent the spread of tuberculosis. This is the recommended method by the World Health Organization and the Centers for Disease Control and Prevention. Swearing or documentation is not as effective as direct observation.

Question 6

In addition to close family members of tuberculosis clients,which other group should the nurse expect to receive prophylactic treatment with antimycobacterial agents?

Accepted Answer

HIV/AIDS clients are at high risk for developing active tuberculosis and are often given prophylactic treatment with antimycobacterial agents. Burn clients and trauma clients may be at increased risk for infections, but this does not necessarily include tuberculosis. Pregnant clients may be treated if they have active tuberculosis, but prophylactic treatment is not typically indicated unless they have significant exposure to someone with the disease.

Question 7

The nurse is preparing to administer INH to a client with tuberculosis and knows that this medication can be administered through which routes?
Select all that apply.

Accepted Answer

INH (Isoniazid) can be administered orally (by mouth) and intramuscularly. These are the common routes for this medication in the treatment of tuberculosis.

Question 8

The nurse is caring for a client being treated with ethambutol in the treatment of tuberculosis.What assessment findings would indicate that the client is experiencing a side effect of this therapy?

Accepted Answer

Ethambutol can cause optic neuritis, which can lead to alterations in color vision, particularly red-green discrimination. The other options are side effects of other medications used to treat TB, but not specifically related to ethambutol.

Question 9

The nurse is reviewing the medical record of a newly admitted client and notes that the client has been diagnosed with a Mycobacterium avium complex (MAC)infection.The nurse knows that this type of infection is believed to be spread via what route?

Accepted Answer

The answer of The nurse is reviewing the medical record...

Question 10

The nurse is caring for a client who has been diagnosed with a form of tuberculosis that is resistant to isoniazid therapy.What drug does the nurse anticipate the client will be prescribed for first-line therapy?

Accepted Answer

Ethambutol is often used as part of the first-line treatment regimen for tuberculosis, especially in cases where there is resistance to isoniazid.

Question 11

The nurse is caring for a client who has been prescribed isoniazid prophylactically for tuberculosis.When used for prophylaxis,isoniazid will be used for what time period?

Accepted Answer

The answer of The nurse is caring for a client...

Question 12

The nurse is caring for a client who has been diagnosed with an infection caused by Mycobacterium avium complex (MAC).The nurse knows that this organism primarily attacks which body systems?

Accepted Answer

Mycobacterium avium complex (MAC) primarily attacks the lungs. It can cause a form of pneumonia in immunocompromised individuals, such as those with HIV/AIDS.

Question 13

The nurse is caring for a pregnant client who is taking isoniazid for the treatment of tuberculosis.The nurse knows that pregnant clients taking isoniazid therapy should also receive:

Accepted Answer

Pregnant clients taking isoniazid therapy should also receive pyridoxine (vitamin B6) to prevent neuritis resulting from isoniazid therapy. Ethambutol, pyrazinamide, and rifampin are not routinely given with isoniazid therapy during pregnancy.

Question 14

The nurse caring for a client who has been diagnosed with a respiratory infection caused by Mycobacterium avium complex (MAC)anticipates that this infection will be treated by what class of antibiotics?

Accepted Answer

Mycobacterium avium complex (MAC) infections are usually treated with macrolide antibiotics, such as azithromycin or clarithromycin, in combination with other antibiotics such as ethambutol or rifampin. Fluoroquinolones, cephalosporins, and penicillins are not typically used to treat MAC infections.

Question 15

A nurse in an outpatient clinic is teaching a client about the criteria for being considered noninfectious.The nurse knows the client has understood the teaching when the client states:

Accepted Answer

A negative sputum culture and smear indicate that the client is no longer shedding infectious agents, such as bacteria. The other options do not necessarily indicate that the client is noninfectious. A normal white blood cell count, negative PPD, and clear chest x-ray may indicate good health but do not necessarily indicate the absence of an infectious process or disease.

Question 16

The nurse is caring for a client who is being discharged on dapsone (DDS)for the treatment of leprosy.The nurse educates the client that it is essential to notify a health care provider when which adverse effects occur?
Select all that apply.

Accepted Answer

The answer of The nurse is caring for a client...

Question 17

The nurse caring for a client who has been diagnosed with Mycobacterium avium complex anticipates that the client could be treated with which medications?
Select all that apply.

Accepted Answer

Mycobacterium avium complex (MAC) infection treatment often includes a combination of antibiotics to effectively combat the infection. Clarithromycin (A) and Azithromycin (B) are macrolide antibiotics commonly used as part of the treatment regimen for MAC. Ethambutol (C) is another antibiotic that is frequently included to prevent or delay the development of resistance. Rifabutin (E) is also used in the treatment of MAC, especially in patients with HIV, to prevent and treat MAC infections. Isoniazid (D), however, is primarily used for the treatment of tuberculosis and is not typically used for MAC infections.

Question 18

The nurse is administering dapsone to a client hospitalized on a medical-surgical unit.The nurse knows that the most frequent adverse effects of dapsone are related to which system?

Accepted Answer

The most frequent adverse effects of dapsone are related to the hematologic system, including anemia, leukopenia, and methemoglobinemia.

Question 19

For the client receiving treatment for tuberculosis,the priority assessment at monthly exams should include the monitoring of:

Accepted Answer

The medication used to treat tuberculosis can potentially cause liver damage, so monitoring liver function is essential to ensure the safety and effectiveness of treatment. Proteinuria, white blood cell counts, and electrolytes are not directly related to tuberculosis or its treatment.
