A nursing instructor asks a nursing student about a client admitted with tuberculosis (TB). What comment by the student indicates that there is a need for further teaching?
1.
"It is transmitted by the airborne route."

2.
"It is a fast-growing infectious disease."

3.
"People who have been in constant close contact with the infected person will need to be tested and treated if necessary."

4.
"The risk for transmission is reduced after the infectious person has received proper medication therapy for 2 to 3 weeks and clinical improvement occurs."

The student's comment that indicates to the nursing instructor that there is a need for more teaching about tuberculosis is "It is a fast-growing infectious disease" (option 2).

Explanation:

Tuberculosis (TB) is a disease whose most common manifestation is pneumonia caused by the granulomatous inflammation of lungs produced by bacteria. The causal agent of TB is Mycobacterium tuberculoisis, a resistant, immobile and very slow-growing alcoholic acid bacillus.

Although TB is a relatively serious infection, it is a slowly progressing infection, causing symptoms insidiously, which is spread by air.  To say that TB is a fast-growing infectious disease, is a mistake that requires correction by the instructor since it reveals the little knowledge that the student has about the disease.
