Multiple Choice

The following are the extra-pulmonary specimens that can be tested for Xpert MTB/Rif test, EXCEPT:

• a. Pleural effusion

• b. Cerebrospinal fluid

• c. Bronchial alveolar lavage fluid

• d. Blood

Multiple Choice

All are true regarding specimen for Xpert MTB/Rif test, EXCEPT:

• a. Good quality sputum specimens are those that are purulent, mucoid, and blood-stained

• b. Grossly bloody or pure blood specimens can be examined for Xpert test

• c. Mucus from the nose and throat are not good specimens

• b. Blood, urine and stool are currently not accepted specimens for Xpert MTB/RIF Testing

Multiple Choice

A sputum of a presumptive TB patient, whose most recent anti-TB treatment was declared Treatment completed, was tested for Xpert MTB/RIF[PD1] . If the result turned out to be “MTB Detected, Rifampicin Resistance Detected”, what will be the complete TB Disease Classification of the patient?

[PD1] Test

• a. Bacteriologically confirmed, pulmonary, new, MDR – TB

• b. Bacteriologically confirmed, pulmonary, retreatment, RR – TB

• c. Bacteriologically confirmed, pulmonary, new, RR – TB

• d. Bacteriologically confirmed, pulmonary, retreatment, MDR – TB

Multiple Choice

In TB disease classification based on drug susceptibility testing, Extensively Drug-resistant TB means:

• a. resistance to more than one first-line anti-TB drug (other than both isoniazid and rifampicin)

• b. any resistance to rifampicin detected using phenotypic or genotypic methods, with or without resistance to other anti-TB drugs.

• c. resistance to one first-line anti-TB drug only

• d. resistance to any fluoroquinolone and to at least one of three second-line injectable drugs in addition to multidrug resistance

Multiple Choice

You received an Xpert test result with MTB detected, Rifampicin resistance not detected. How will you record the result in the presumptive TB masterlist following guidelines?

• a. T in red Ink

• b. RR in blank ink

• c. T in blue ink

• d. RR in red ink

Multiple Choice

What is the next best thing to do for patients below 15 years old with negative Xpert MTB/Rif result, but with persistent signs and symptoms of TB?

• a. Retrieve CXR or refer the patient for CXR if not done yet.

• b. Refer the patient to pulmonologist to rule out other diseases

• c. Consider giving one week of broad-spectrum antibiotics if not given before.

• d. Recollect for re-testing of Xpert then do TST

Multiple Choice

What is the form used to ensure that all screened presumptive TB have been recorded?

• a. Presumptive TB Masterlist

• b. Screening form

• c. TB treatment Card

• d. NTP register

Multiple Choice

Which of the following is a positive TST result?

• a. Induration of >5mm in a malnourished child

• b. 8 mm induration in a healthy child

• c. No induration noted but with erythema

• d. A&C

Multiple Choice

It is used to screen resistance to FQs and SLIs.

• a. GeneXpert MTB/RIF Test

• b. First Line LPA

• c. Second Line LPA

• d. TB LAMP

Multiple Choice

In TB disease classification based on drug susceptibility testing, mono-resistance means:

• a. resistance to at least both isoniazid and rifampicin

• b. resistance to one first-line anti-TB drug only

• c. resistance to any fluoroquinolone and to at least one of three second-line injectable drugs in addition to multidrug resistance

Multiple Choice

The following are the result of Xpert MTB/Rif test, EXCEPT:

• a. T

• b. RR
