Which of the following medications can cause serotonin syndrome?

A. "I will use this device 20 times per hour while I am awake each day.": Correct. This statement requires correction. While frequent use is recommended, 10 times per hour is typically sufficient. Overuse may cause hyperventilation or dizziness.

B. "I should be in a sitting position when using this device.": Correct. A sitting or semi-Fowler’s position promotes lung expansion and is the proper position for using an incentive spirometer.

C. "I will hold my breath for 3 seconds after I feel like I cannot inhale any more breath.": Correct. Holding the breath allows for alveolar expansion and better lung recruitment.

D. "I will exhale completely before placing my lips around the mouthpiece.": Correct. Exhaling fully ensures that the next inhalation is deep and effective.

A. Discharge teaching: Phase III of post-anesthesia care focuses on preparing the patient for discharge, including teaching about post-operative care, medication instructions, and follow-up care.

B. Recovery from anesthesia: This occurs in Phase I, where patients are closely monitored as they emerge from anesthesia and regain protective reflexes.

C. Urinary catheterization if no voiding: This may be considered in Phase II, especially if urinary retention is present, but is not a defining activity of Phase III.

D. Vital signs every 15 to 30 minutes: Frequent monitoring of vital signs is a key part of Phase I, when patients are at the highest risk for complications.
