When the Nurse Enters the Room, the Patient Is Laughing

When the nurse enters the room, the patient is laughing out loud at something on TV. The patient stops and apologizes for the laughter, saying, "I guess I ought not be laughing at all since I am stuck here with two broken legs." The nurse can use evidence-based information when she responds:

A) "Laughter is nearly always a cover up for anxiety when facing a long rehabilitation."
B) "Long periods of laughter decrease the amount of oxygen available to your body for healing."
C) "Laughter in a hospital is often distracting and depressing to other patients nearby."
