B
Sympathetic stimulation of the heart causes A. a decreased rate and force of myocardial contraction. B. an increased rate and force of myocardial contraction. C. aterm-20n excitatory response that stimulates the brain to generalized decreased activity. D. decreased blood flow and impaired digestion.
B
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 increased myocardial activity and increase heart rate? A. Alpha1 B. Beta1 C. Beta2 D. Alpha2
B
The nurse is assessing a client who has urinary hesitation and occasional overflow incontinence. What adrenergic receptors may be overstimulated in this client? A. Alpha-2 B. Alpha-1 C. Beta-1 D. Beta-2
B
When there is stimulation of the SNS, blood is diverted away from the GI tract. What indicates this diversion? A. Increased blood pressure B. Decreased bowel sounds C. Decreased immune reactions D. Increased blood glucose levels
B
Nicotinic receptors are found in which area? A. GI tract B. Sweat glands C. Autonomic basal ganglia D. Bladder
C
The body uses tyrosine in the diet to make what substance? A. Serotonin B. Estrogen C. Norepinephrine D. Glutamate
C
The nurse is assessing a client. What assessment finding is the clearest indicator of autonomic function? A. The client can discern hot sensation from cold B. The client's hearing is intact C. The client's respiratory rate is 22 breaths per minute D. The client's muscle strength is equal bilaterally
C
A client admitted to a cardiac unit asks why a rest period is required each afternoon. The nurse's response should be based on what information regarding the PNS? A. "The nurses will be able to get some rest from the clients and other health care providers." B. "It is a time for all health care providers to complete documentation and review test results." C. "Families and visitors are encouraged to get lunch and rest during this time." D. "Clients are encouraged to rest and relax during this time, free of families and visitors."

D
During ambulation after surgery, the skeletal muscle produces contraction. What receptor is located in motor nerves and skeletal muscle? A. Acetylcholine B. Muscarinic C. Beta adrenergic D. Nicotinic
D
The nurse is caring for a client with asthma who has been administered albuterol in order to promote bronchodilation and relieve shortness of breath. When giving this medication, the nurse has affected the client's autonomic nervous system by: A. stimulating beta2-receptors. B. decreasing the reuptake of acetylcholine. C. converting a larger proportion of dopamine to norepinephrine. D. antagonizing alpha2-receptors.
A
The nurse is caring for a client who is known to have deficient levels of dopamine because of a dietary lack of tyrosine. The nurse should expect to assess for evidence of: A. hyperfunction of the sympathetic nervous system. B. overstimulation of nicotinic receptors. C. decreased adrenergic response. D. increased adrenergic response.
C
The nurse is conducting an assessment of a newly admitted client. What assessment finding should suggest to the nurse that the client's muscarinic cholinergic receptors are being stimulated? A. The client describes a frontal lobe headache. B. The client's blood pressure is 119/72 mmHg. C. The client's attention span is unusually short. D. The client has "pinpoint" pupils.
