Answer #1

18) Option ( C) is correct. ( Review client's history for possible exposure to TB)

Explaination :-

The Mantoux tuberculin skin test is one method of determining vwhether a person is infected with Mycobacterium Tuberculosis. The skin test reaction should be read between 48 and 72 hours after administration. A person who does not return within 72 hours will need to be rescheduled for another skin test. The reaction should be measured in millimetres of induration. The reader should not measure erythema ( redness). The diameter of indurated area should be measured across the forearm.
