Why do acute pain and anxiety increase pulse rates?
- A.
Sympathetic nerves are suppressed
- B.
Parasympathetic nerves are suppressed
- C.
Parasympathetic nerves are stimulated
- D.
Sympathetic nerves are stimulated
Correct Answer
D. Sympathetic nerves are stimulatedExplanation
Acute pain and anxiety trigger the body's fight-or-flight response, which is controlled by the sympathetic nervous system. When this system is activated, it releases stress hormones like adrenaline, leading to an increase in heart rate, among other physiological changes. This response prepares the body to either confront or flee from perceived threats. The stimulation of sympathetic nerves rapidly accelerates heart rate to ensure that blood is quickly circulated to vital organs and muscles, providing the energy and oxygen needed to respond to the stressor.Rate this question:

Why do older adults experience an increase in systolic pressure?
- A.
Increased vessel flexibility
- B.
Decreased vessel elasticity
- C.
Enlarged vessel dexterity
- D.
Diminished vessel porosity
Correct Answer
B. Decreased vessel elasticityExplanation
As individuals age, their blood vessels tend to lose elasticity due to changes in the connective tissue that makes the vessel walls less compliant. This decreased elasticity means that the vessels cannot expand as readily when blood is pumped through them by the heart, particularly during systole, which is when the heart pumps blood out into the arteries. Consequently, this resistance to expansion causes an increase in systolic pressure. High systolic pressure in older adults is a common issue and can contribute to the risk of cardiovascular diseases, making monitoring and managing blood pressure an essential aspect of healthcare for the elderly.Rate this question:
