Answer to Question 1

ANS: B, C, D, E, F
Inaccurate pulse oximetry readings can be caused by outside light sources, carbon monoxide (caused by smoke inhalation or poisoning), patient motion, jaundice, intravascular dyes (methylene blue), nail polish, artificial nails, metal studs, or dark skin. SpO2 is a reliable estimate of SaO2 when the SaO2 is over 70.

Answer to Question 2

ANS: A, B, D
Obesity, cigarette smoking, and heavy alcohol consumption are risk factors linked to hypertension. Weight loss and regular exercise can decrease the risk for hypertension.
