A patient is generally considered to have orthostatic vital signs when:

A) the systolic BP increases and the diastolic BP decreases when going from a lying to a sitting position. B) the heart rate increases by 20 beats/min or more when going from a supine to a standing position. C) the respiratory rate becomes fast and the depth becomes shallow when he or she suddenly stands up. D) he or she experiences chest pain and a rapid, irregular heart rate when going from a seated to a standing position.

You have been called for a geriatric patient with advanced dementia. The staff at the geriatric extended care facility believes that the patient has a urinary tract infection. At bedside, you find the patient to be confused and aggressive. She is on constant oxygen at 3 lpm for COPD. During transport, she repeatedly yells at you and strikes out at you. You would respond by

A) Applying a nonrebreather face mask with 3 lpm of oxygen B) Contacting advanced life support for administration of a sedative C) Tightening the straps so that she is tightly restrained to the stretcher D) Moving away from the patient so she cannot strike you
