You are monitoring blood pressure during mechanical ventilation of a patient with pneumonia. A temporary increase in blood pressure occurs when the patient coughs. This temporary spike in blood pressure represents what type of variability?
a. Artifact
b. Factitious event
c. Physiologic variation
d. Instrument drift
ANS: C
The signal itself can exhibit a random variability related to the inherent imprecision of the signal or due to normal physiologic variability in the patient. Blood pressure, for example, changes within a certain range for many reasons.

You are transporting a patient who has a history of simple partial seizures. During transport, she experiences a simple partial seizure involving her right arm. Her pulse is 92, respirations are 14 breaths/min and adequate, blood pressure is 168/88 mmHg, and SpO2 is 98%. Your primary concern would be:
A) Administering supplemental oxygen via nasal cannula B) Loss of bowel or bladder control C) Placing the patient's arm tightly in a sling to prevent injury D) Progression to a generalized seizure
