NURS 3100 Exam 3 Verified Study Questions And
Answers 2024 Updated Tests
A client's heart rate is 72 beats per minute with a regular rhythm. How does the nurse interpret this data in relation to
the client's peripheral nervous system? Select all that apply.
A. The sympathetic system is in control.
B. The parasympathetic system is dominating.
C. Both parasympathetic and sympathetic systems are influencing cardiac status.
D. The autonomic nervous system is affecting cardiac status.
E. The somatic nervous system is affecting cardiac status. ANS B, C, D
Restful cardiac response indicates that the primary input is from the parasympathetic system.
These two systems work in tandem to regulate the cardiac response.
Both the sympathetic and parasympathetic systems are part of the autonomic system.
A nurse is reading about the development of drugs that inhibit the parasympathetic nervous system. The nurse would
look for articles about which drug classes? Select all that apply.
A.Anticholinergics
B. Parasympathomimetics
C. Parasympatholytics
D. Cholinergics
E. Muscarinic blockers ANS A, C, E
Anticholinergics inhibit the parasympathetic nervous system.
Parasympatholytic drugs inhibit the parasympathetic nervous system.
Muscarinic blockers inhibit the parasympathetic nervous system.
Which is an adrenergic receptor associated with the sympathetic nervous system?
A. Dopamine
B. Muscarinic
C. Norepinephrine
D. Beta ANS D
The adrenergic receptors associated with the sympathetic nervous system include both beta and alpha receptors.
,A client has been prescribed an oral drug containing atropine. The nurse would hold the drug and contact the
prescriber if the client states which of the following? Select all that apply.
A. "I would like to wait a few minutes to take this as I just drank some aloe juice."

B. "It is really important to take my medication on time."
C. "I must take this medication immediately before eating a full meal."
D. "I will need to increase my fluid intake with this medication." ANS B
Maintaining an optimum blood level of the drug is crucial in promoting muscle functioning, so it is important for the
client to take his medication on time and as directed.
The health-care provider has ordered bethanechol (Urecholine), a cholinergic drug, for the client with urinary
retention. The client also has an enlarged prostate gland. What is the priority action by the nurse?
A. Administer the drug and measure urinary output.
B. Hold the drug and contact the health-care provider.
C. Administer the drug and push fluids.
D. Hold the drug and prepare to catheterize the client. ANS B
Bethanechol (Urecholine) relaxes the urinary sphincter and increases voiding pressure. It is contraindicated with any
physical obstruction of the urinary tract, such as an enlarged prostate gland.
A preoperative client will be receiving glycopyrrolate (Robinul), which is an anticholinergic drug. The client asks
the nurse, "Why do I need to take that medication?" What is the best response by the nurse?
A. "It will help you breathe better during surgery."
B. "It will increase your urinary output during surgery."
C. "It will help maintain your blood pressure during surgery."
,D. "It will decrease your respiratory secretions during surgery." ANS D
Anticholinergics dry secretions; a decrease in respiratory secretions is indicated prior to surgery.
The nurse is preparing to administer benztropine (Cogentin), which is an anticholinergic drug. The nurse
understands this drug is contraindicated in which client?
A. The client with tachycardia.
B. The client with a fractured femur.
C. The client with diarrhea.
D. The client with an irritable colon. ANS A
Anticholinergic drugs increase the heart rate; a client with tachycardia should not receive benztropine (Cogentin).
The nurse is preparing to administer medications to a group of clients. One of the medications is atropine, an
anticholinergic drug. This drug is contraindicated in which client?
A. The client with glaucoma.
B. The client with hyperthyroidism.
C. The client with lung cancer.
D. The client with a hiatal hernia. ANS A
Anticholinergic drugs can increase pressure in the eye; they must be avoided in clients with glaucoma.
The health-care provider orders dicyclomine (Bentyl), an anticholinergic drug, for a client. What is the nurse's
priority assessment prior to administering this drug?
A. Is the client dizzy upon standing?
B. Is the client able to urinate?
C. Does the client have a history of alcoholism?
D. Does the client have light sensitivity? ANS B
Anticholinergic drugs can cause or increase urinary hesitancy or retention.
The client is quadriplegic and receives the anticholinergic drug oxybutynin (Ditropan) to increase his bladder
capacity. What is an important assessment of this client by the nurse?
A. Is he gaining weight?
B. Is he irritable?
C. Is he lethargic?
D. Is he constipated? ANS D
, Anticholinergics slow gastrointestinal (GI) motility and can increase the risk for constipation.

has occurred when the students make which statement(s)?Select all that apply.

B. "The peripheral nervous system has mainly sensory functions."
C. "The somatic nervous system gives us voluntary control over our gastrointestinal (GI) tract."
D. "The nervous system helps us react to environmental changes."
E. "The somatic nervous system gives us voluntary control over moving." ANS A, D, E
The central nervous system includes the brain and spinal cord. The nervous system provides reaction to
environmental changes. The somatic nervous system provides voluntary control over moving.
The nursing instructor teaches the student nurses about the autonomic nervous system. The instructor determines
