Question 1

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

Sputum culture and smear must be consistently negative over a period of time to consider the client noninfectious. The PPD test measures the client's reaction to tuberculosis but does not indicate infectiousness. A normal white blood cell count and a clear chest X-ray may indicate improvement in the client's condition, but do not confirm noninfectiousness.

Question 2

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 increased risk for developing active TB due to their weakened immune system. Prophylactic treatment with antimycobacterial agents is recommended for these clients to prevent active TB from developing. While burn and trauma clients may be at risk for acquiring TB in certain settings, they would not typically receive prophylactic treatment unless they had close contact with a client who had active TB. Prophylactic treatment is generally not recommended for pregnant clients, although treatment may be necessary if there is evidence of active TB.

Question 3

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, specifically resulting in hemolytic anemia and methemoglobinemia.

Question 4

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 ocular toxicity, including changes in color vision, blurred vision, and decreased visual acuity. White patches in the mucous membranes, ringing in the ears, and alteration in smelling are not common side effects of ethambutol.

Question 5

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

When sputum culture and smear are negative, it means there is no active infection in the respiratory system and the client is considered noninfectious. The other options do not necessarily indicate that the client is noninfectious. A normal white blood cell count can be seen in both infectious and noninfectious states. A negative PPD only indicates that the client is not infected with tuberculosis, but they may still have other infections. A clear chest x-ray does not necessarily mean that the client is noninfectious as there can be asymptomatic infections or infections in other parts of the body.

Question 6

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? Note: Credit will be given only if all correct choices and no incorrect choices are selected.Standard Text: 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 7

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, which is a vitamin supplement that helps to prevent the rare but serious side effect of peripheral neuropathy that can occur with isoniazid therapy. Ethambutol and pyrazinamide are not routinely prescribed for pregnant clients with tuberculosis. Rifampin can be used to treat tuberculosis in pregnancy, but it is not necessary for a client who is only receiving isoniazid therapy.

Question 8

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) requires the nurse to physically observe the client taking the medication to ensure adherence to the medication regimen for tuberculosis treatment. Swearing or documentation by the client or family member is not sufficient to ensure medication adherence.

Question 9

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 can decrease the effectiveness of dapsone, which could lead to negative health outcomes for the client. Potassium, aspirin, and Viagra do not have known interactions with dapsone.

Question 10

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 hematologic adverse effects such as methemoglobinemia, hemolytic anemia, and agranulocytosis. Therefore, monitoring the hematologic system is important when administering this medication. Monitoring the other systems may also be important but not as critical as the hematologic system.

Question 11

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) is typically treated with macrolide antibiotics, such as azithromycin or clarithromycin, in combination with other drugs. Fluoroquinolones, cephalosporins, and penicillins are not typically used to treat MAC infections.

Question 12

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 13

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

Accepted Answer

Monitoring liver function is important for clients receiving treatment for tuberculosis because the medications used can cause liver damage or hepatitis. Proteinuria, white blood cell counts, and electrolytes are not directly affected by tuberculosis or its treatment.

Question 14

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? Note: Credit will be given only if all correct choices and no incorrect choices are selected.Standard Text: Select all that apply.

Question 15

The nurse caring for a client who has been diagnosed with Mycobacterium avium complex anticipates that the client could be treated with which medications? Note: Credit will be given only if all correct choices and no incorrect choices are selected.Standard Text: 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 16

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
