A patient with TB who is in respiratory isolation must go to the x-ray department. Which action should the nurse take?

Place a mask over the patient's nose and mouth.

Notify the x-ray department that the test must be cancelled.

Place a gown and gloves on the patient.

Call the x-ray department to make sure the waiting room is empty.

Answer and Explanation

The Correct Answer is A

A. Place a mask over the patient's nose and mouth: When a patient with active TB leaves the isolation room, they must wear a surgical mask to prevent airborne transmission. This protects others from inhaling Mycobacterium tuberculosis in shared spaces.

B. Notify the x-ray department that the test must be cancelled: There is no need to cancel the diagnostic test. Proper precautions like masking the patient enable safe transport and continuation of necessary medical care.

C. Place a gown and gloves on the patient: Gowns and gloves are used for contact precautions, not airborne. TB transmission is airborne, and a surgical mask is the appropriate protective measure for the patient not gowning or gloving.

D. Call the x-ray department to make sure the waiting room is empty: While minimizing exposure is ideal, it is not sufficient or necessary if the patient wears a mask. Standard protocol centers on masking the patient and notifying departments of isolation status, not on room occupancy control.

Correct Answer is C

Explanation

A. RSV can survive on nonporous surfaces for about 60 minutes:RSV can actually survive on hard, nonporous surfaces like countertops and toys for several hours often up to 6 hours. Stating 60 minutes underestimates the virus's survival time.

B. RSV can live on skin or paper for up to a few seconds after contact:RSV can survive on hands for about 30 minutes and on tissues or paper for several hours. Saying “a few seconds” downplays its persistence and the potential for transmission through casual contact.

C. Frequent handwashing can decrease the spread of the virus:Handwashing is one of the most effective measures to prevent RSV transmission. Because the virus spreads through direct contact with respiratory secretions and contaminated surfaces, frequent hand hygiene is essential in high-risk environments like daycare centers.

D. RSV is transmitted through particles in the air:RSV is mainly spread through large respiratory droplets and direct contact, not through airborne particles that remain suspended.

A. Change the chest tube drainage system. B. Document the findings. C. Check for an air leak. D. Notify the health care provider.

Correct Answer is B

Explanation

A. Change the chest tube drainage system:Changing the entire drainage system is not warranted for intermittent bubbling in the water seal chamber. This action is appropriate for malfunctioning systems or when there is a significant system compromise such as contamination or leakage.

B. Document the findings:Intermittent bubbling in the water seal chamber is an expected finding during active pneumothorax as air escapes from the pleural space. This indicates that the chest tube is functioning, and documenting the observation is the appropriate action.

C. Check for an air leak:Continuous, not intermittent, bubbling may indicate an air leak. Intermittent bubbling usually occurs during expiration or coughing and does not require investigation unless it becomes continuous or excessive.

D. Notify the health care provider:There is no immediate need to notify the provider for expected intermittent bubbling. This is a normal finding in some phases of pneumothorax resolution and does not indicate a complication requiring urgent intervention.
