High Respiratory Rate
A health care provider orders the collection of a sputum specimen from a client with a suspected bacterial infection. Which action best ensures a usable specimen?
Instruct the client to inhale deeply and then cough
Which teaching about the humidifier is important for the nurse to provide to a client using oxygen?
