Correct Answer: A

Rationale: The increased rate of pertussis in adults is thought to be caused by decreasing immunity after childhood immunization. Immunization is the most effective method of protecting communities from infectious diseases. Hand washing should be taught, but pertussis is spread by droplets and contact with secretions. Supportive care does not shorten the course of the disease or the risk for transmission. Taking antibiotics as prescribed does assist with decreased transmission, but patients are likely to have already transmitted the disease by the time the diagnosis is made.

Rationale: The air entrainment ports regulate the O2 percentage delivered to the patient, so they must be unobstructed. The other options refer to other types of O2 devices.

Correct Answer: B

The other patients also need assessment as soon as possible, but they do not need to be assessed as urgently as the patient with tachypnea.

Correct Answer: A

Rationale: Ozone in the stratosphere absorbs harmful UV radiation, shielding life on Earth.
