The instructions which the nurse should include on the list after treating a patient with tuberculosis include the following:
- Activities should be resumed gradually.
- A sputum culture is needed every 2 to 4 weeks once medication therapy is initiated.
- Respiratory isolation is not necessary because family members already have been exposed.
- Cover the mouth and nose when coughing or sneezing and put used tissues in plastic bags.
<h3>What is Tuberculosis?</h3>
This refers to a disease which is caused by a bacterium called Mycobacterium tuberculosis. This bacteria attacks the lungs thereby resulting in symptoms such as coughing, weight loss etc.
After being treated, the patient can resume activities and don't need any isolation but should ensure that the mouth and nose are covered and disposed properly when coughing.
A sputum culture is needed every 2 to 4 weeks once medication therapy is initiated so as to confirm the absence of the bacteria so as to discontinue drug usage.

People who become dependent on a drug may become tolerant to that drug. This means they need to use more and more of the drug to get the same effect or to avoid withdrawal symptoms. When people are dependent they believe they have to use the drug to do certain things or feel a certain way.
Answer:
Polymerase chain reaction, or PCR, is a technique to make many copies of a specific DNA region in vitro (in a test tube rather than an organism).
PCR relies on a thermostable DNA polymerase, Taq polymerase, and requires DNA primers designed specifically for the DNA region of interest.
In PCR, the reaction is repeatedly cycled through a series of temperature changes, which allow many copies of the target region to be produced.
PCR has many research and practical applications. It is routinely used in DNA cloning, medical diagnostics, and forensic analysis of DNA.
PCR:
Polymerase chain reaction (PCR) is a common laboratory technique used to make many copies (millions or billions!) of a particular region of DNA. This DNA region can be anything the experimenter is interested in. For example, it might be a gene whose function a researcher wants to understand, or a genetic marker used by forensic scientists to match crime scene DNA with suspects.
Typically, the goal of PCR is to make enough of the target DNA region that it can be analyzed or used in some other way. For instance, DNA amplified by PCR may be sent for sequencing, visualized by gel electrophoresis, or cloned into a plasmid for further experiments.
PCR is used in many areas of biology and medicine, including molecular biology research, medical diagnostics, and even some branches of ecology.
