A nurse is providing teaching to a parent of a child who has varicella. Which of the following statements should the nurse include in the teaching?

A. Since the sputum culture is positive for M. tuberculosis, contact precautions are necessary to prevent the spread of the infection to others. These precautions include wearing gloves and a gown when in contact with the client or their environment.
B. Ethambutol is one of the first-line medications used in the treatment of tuberculosis (TB). It works by inhibiting the growth of TB bacteria, thereby helping to eliminate the infection.
C. A monthly TB skin test is not a standard part of treatment for a patient with active TB and is therefore contraindicated.
D. Isoniazid is another first-line medication used in the treatment of TB. It works by killing the TB bacteria and is often used in combination with other medications to treat active TB infection.
E. Since the sputum culture is positive for M. tuberculosis, airborne precautions are necessary to prevent the transmission of TB via airborne droplets. These precautions include wearing an N95 respirator mask and placing the client in a negative-pressure isolation room.
F. Pyrazinamide is part of the standard multidrug regimen used to treat TB. It works by killing the TB bacteria in different stages of their life cycle, helping to eradicate the infection more effectively.
G. Rifampin is another essential medication used in the treatment of TB. It works by inhibiting the synthesis of bacterial RNA, thereby killing the TB bacteria. Rifampin is usually given in combination with other TB medications to prevent drug resistance.

A. To prevent infection and ensure proper healing, it's usually advised to avoid submerging the catheterization site in water until it has adequately healed.

B. There is generally no need for a special diet such as a clear liquid diet following cardiac catheterization unless specified for other reasons.
C. Following cardiac catheterization, it's important to keep the pressure dressing in place to ensure proper healing and prevent bleeding from the catheterization site. Typically, the dressing is removed the next day under safe, controlled conditions.
D. Typically, children can return to school within a few days after cardiac catheterization unless complications arise or there are other specific medical advisories.
