Chap. 29 Autonomic Nervous System
What is NOT a function of the body's homeostatic control systems?
Feed cells under stress
Which statements are true regarding the autonomic nervous system receptors?
Medications can either stimulate or inhibit ANS Drug effects depend on the branch of the ANS involved
What would be an example of an autonomic response he may have control over?
The rate of his heart beat
In the sympathetic nervous system, which is the origin of the CNS nerves?
Thoracic spinal cord
What would be discussed when describing the parasympathetic nervous system?
Vagus nerve
Which would occur if the drug stimulated the Beta-2 receptors?
Vasodilation
The physiology instructor explains to the nursing students that beta-2 stimulation leads to?
Vasodilation of blood vessels
Alpha 1 receptors
vasoconstriction
A patient exercises 30min today. The client has not had an exercise regimen for many years. What autonomic neurotransmitter will be released,
Acetylcholine
The skeletal muscles during the use of the incentive spirometer are stimulated by which neurotransmitter?
Acetylcholine
Nictonic receptors are found where?
Adrenal Medulla
The anatomy and physiology instructor is discussing adrenergic receptors with the nursing class. What adrenergic receptor would the instructor tell the students is found in the heart and can stimulate myocardial activity and increase heart rate?
Beta 1
Nursing students are giving an oral presentation on the parasympathetic nervous system, how would they describe Muscarinic receptors?
Classification based on research with a mushroom plant alkaloid
Monoamine oxidase is an enzyme that breaks down which neurotransmitter?
Norepinephrine
A patient has received the evening meal and is recovering from surgery, what nervous system is stimulated?
Parasympathetic nervous system
Alpha 2 receptors
smooth muscle contraction and neurotransmitter inhibition
The nurse assessed a client at 8am and got a BP of 111/70. Two hours later the clients BP was 130/81. The nurse should attribute this change to what action within the autonomic nervous system?
Stimulation of Beta - receptors
The nurse is caring for a client with asthma who has been experiencing shortness of breath and who has been administered a medication to cause bronchodilation. What aspect of autonomic nervous function has the nurse most likely influenced?
Stimulation of beta-adrenergic receptors
Beta 2 receptors
bronchodilation
Beta 1 receptors
increase heart rate
What is the resulting physiologic effect when the parasympathetic nervous system is stimulated?
increased GI motility is
The body uses tyrosine in the diet to make what substance?
norepinephrine
