NUR 304 Test 81. Fentanyl
Answer
0.1 mg = 10mg of morphine IV administration in perioperative/ ICU care
Transdermal (patch)— replace every 72 hours and releases over 6-12 hour period
2. Peripheral Nervous System
Answer
Efferent --> sympathetic nervous system (auto- nomic)
Afferent --> parasympathetic nervous system (somatic)
3. Sympathetic Nervous System
Answer
Adrenergic receptors (Alpha 1, Beta 1, Alpha 2,
Beta 2)
neurotransmitters
N/E (norepinephrine & epinephrine)
4. Parasympathetic Nervous System
Answer
Cholinergic receptors (Nicotinic-- muscle, Muscarinic-- internal organs)
neurotransmitter
Ach (acetylcholine)
5. Sympathetic Nervous System (fight or flight-- responds to stressful situa- tions); what are
,the physiological responses to it being activated? ADRENER-
GIC
Answer
pupils dilate
decreased saliva production increased heartrate and force
bronchi dilated, bronchial muscles relaxed
norepinephrine and epinephrine secreted from adrenal medulla (bind to the alpha and beta
receptors)
GI motility and peristalsis reduced bladder wall relaxed, sphincter closed decreased urine
secretion
increased conversion of glycogen to glucose
6. Parasympathetic Nervous System (rest and digest, anabolic, maintaining essential body
systems); what are the physiological responses of parasym- pathetic nervous system being
activated? CHOLINERGIC
Answer
-pupils constrict
-GI motility and digestion increases, gastric secretions increase
-heart rate and force reduced
-saliva production increases
-mucus production increases
-hepatic production/ output of glucose can shut down/ reduce
-bronchial muscles contract
-urinary secretions increase
-bladder wall contracts & sphincter relaxed
-acetylcholine binds to cholinergic receptors (muscarinic, nicotinic)
7. What are the main functions of Sympathetic Nervous System?
Answer
Regulate body temp, regulate cardiovascular system, stimulates fight or flight response
, bronchi dilated, heart rate and force increase, secretions decrease
8. What are the main functions of the parasympathetic nervous system?
Answer
rest and digest
elimination (bowel and urine) increases secretions increase (saliva, mucus, GI)
GI motility/ digestion increases pupils constrict
bronchial smooth muscles contract
heart rate reduced
9. adrenergic drugs
Answer
also called sympathomimetic drugs because they produce effects similar to sympathetic
nervous system
agonists stimulate, antagonists inhibit
direct-acting--> directly act on adrenergic receptors indirect-acting--> does not directly act on
receptors dual-acting --> both
10. alpha-1 receptor
Answer
dilates pupils (mydriasis), vasoconstricts b.v. and increases BP, increased closure of urinary
bladder sphincter
11. alpha-2 receptor
Answer
pancreas moderates insulin secretion, nerve membranes decrease release of NE
12. beta-1
