Prep U Ch. 46 ANS and CNS
pupil dilation, increased blood pressure
A client has been administered phenylephrine, a medication that affects alpha1-receptors. The nurse should anticipate what effects on the client? SATA - pupil dilation - increased BP - drowsiness - decreased blood glucose - flushed skin
ANS
A patient is admitted to the emergency room after a car accident. Based on the experience of the emergency room nurse, what system will affect a response to the emergency? - central nervous system - cardiovascular system - endocrine system - autonomic nervous system
it mimics the sympathetic nervous system
A patient is receiving albuterol as a bronchodilator. How does this agent work? - it mimics the sympathetic nervous system - it mimics the cardiotonic effects of digoxin (lanoxin) - it mimics the parasympathetic nervous system - it mimics the central nervous system
increased saliva production, hyperactive bowel sounds, constricted pupils
The nurse administers a medication that stimulates the parasympathetic nervous system. What manifestations would indicate the medication is having the desired effect? SATA - urinary incontinence - increased saliva production - hyperactive bowl sounds - elevated heart rate - constricted pupils
"The medication will cause my heart rate to increase and will cause palpitation"
The nurse educates a client diagnosed with asthma concerning the important aspects about the prescribed selective beta2-adrenergic agonist inhaler. Which client statement indicates the need for further clarification? - "The medication will bind to beta2 receptors and activate the physiologic response" - "The inhaler will cause my bronchi to dilate and make it easier for me to breathe" - "The medication will cause my heart rate to increase and will cause palpitation" - "Beta2 receptors are in the respiratory tract and the bronchi"
alpha 1
The nurse is assessing a client who has urinary hesitation and occasional overflow incontinence. What adrenergic receptors may be overstimulated in this client? - alpha 1 - beta 1 - alpha 2 - beta 2
increased cardiac output, increased blood pressure
The nurse prepares to administer a selective alpha-adrenergic agonist medication to a client diagnosed with shock. What would the nurse consider to be therapeutic or desired effect(s) based upon the characteristics of the prescribed medication? SATA - bronchodilation - bradycardia - increased cardiac output - increased blood pressure - hypoglycemia
decreased heart rate
Which of the following effects might occur following the administration of a cholinergic drug? - constriction of blood vessels in the skin - decreased heart rate - pupil dilation - absorption of nitrous oxide by the endothelium of blood vessels
alpha 1 receptors
Which receptor is responsible for increasing blood pressure? - alpha 1 receptors - alpha 2 receptors - beta 1 receptors - beta 2 receptors
drug effects depend on the branch of the ANS involved, medications can either stimulate or inhibit the ANS
Which statements are correct regarding the autonomic nervous system receptors? SATA - there are no drugs that affect the ANS or receptors - the nurse does not need to know about the receptors in the ANS - drug effects depend on the branch of the ANS involved - ANS drugs affect only specific organs and not the whole body - medications can either stimulate or inhibit the ANS
