c. Pulse oximeter Respons e Feedback : d. Yankauer suction tip catheter A blood pressure cuff is needed. The diastolic aortic pressure is a good clinical measure of afterload. Afterload is the resistance to left ventricular ejection. In hypertension the afterload increases, making cardiac workload also increase. A pulse oximeter is used to monitor the level of arterial oxygen saturation; it will not help determine increased afterload. While an oxygen cannula may be needed to help decrease the effects of increased afterload, it will not help determine the presence of afterload. A Yankauer suction tip catheter is used to suction the oral cavity.

b. Decreased heart rate c. Dilated pupils Respons e Feedback : d. Elevated blood pressure Decreased heart and respiratory rates, blood pressure, and oxygen consumption and increased alpha brain activity and peripheral skin temperature characterize the relaxation response. The physiological cascade of changes associated with the stress response includes increased heart and respiratory rates, muscle tightening, increased metabolic rate, a sense of foreboding, fear, nervousness, irritability, and a negative mood. Other physiological responses include elevated blood pressure; dilated pupils; stronger cardiac contractions; and increased levels of blood glucose, serum cholesterol, circulating free fatty acids, and triglycerides.
