Unit 5: Chapter 26 (Karch 7th Ed) - Narcotics, Narcotic Antagonists, and Antimigraine Agents Flashcards
- A geriatric patient received a narcotic analgesic before leaving the post-anesthesia care unit to return to
the regular unit. What is the priority nursing action for the nurse receiving the patient on the regular
unit?
A) Administer a non-steroidal anti-inflammatory drug.
B) Encourage fluids.
C) Create a restful, dark, quiet environment.
D) Put side rails up and place bed in low position.
Ans: D
Feedback:
Older patients are more susceptible to the central nervous system effects of narcotics; it is important to
ensure their safety by using side rails and placing the bed in the low position in case the patient tries to
get up unaided. Postoperative patients are allowed nothing by mouth until bowel function returns so an
oral medication or encouraging fluids would not be appropriate. This patient will require careful
observation for respiratory depression, so a dark room would be unsafe.
- A patient who is experiencing severe pain is administered a narcotic. What would the nurse write in the
plan of care as a desirable and measurable outcome for this patient?
A) A shorter period of time between requests for medication
B) Reduced complaints about limited movement
C) Lack of restlessness and ability to sustain one position
D) Increased autonomy in providing AM care
Ans: D
Feedback:
Monitor patient response to the drug (e.g., relief of pain, sedation).When pain is being adequately
managed with opioid therapy, a desirable and measurable outcome would be that the patient is able to
be more autonomous in providing care in the morning. Shorter periods between requests for medication
would not be a desirable outcome because it is not an indicator of pain control given that some patients
are reluctant to ask for medicine even though they are in pain. Patients in pain tend not to move for fear of exacerbating the pain, so lack of movement can be an indication the patient is in pain. Just because
the patient does not complain of pain doesn’t mean he isn’t experiencing pain.
- The health care provider orders oral (PO) codeine as an adjunctive therapy to pain control medication.
What order would be appropriate for the nurse to administer?
A) Codeine 5 mg PO every 6 hour
B) Codeine 10 mg PO every 4 hour
C) Codeine 15 mg PO every 2 hour
D) Codeine 20 mg PO every 4 hour
Ans: D
Feedback:
The correct dosage for codeine administered for pain by mouth is 15 to 60 mg q 4 to 6 hour. The other
options are incorrect oral dosages because they are too low a dose or give an incorrect dosing
frequency.
- A patient with migraine headaches is changed from an ergot to a prescription for a triptan. The nurse
has completed teaching related to the drug. What statement would indicate she has a clear
understanding of the new drug?
A) My life is over. I can’t function not knowing when I’m going to have a headache.
B) I will not have to avoid driving because this medication isn’t sedating.
C) I should not experience as many adverse effects from my new medication.
D) I take my medication every hour when I have a headache
Ans: C
Feedback:
Triptans are a new class of selective serotonin receptor blockers that cause vasoconstriction; they are
not associated with as many systemic adverse effects experienced in ergot therapy. Triptan therapy will
enable her to live a near normal life even during headaches. Although adverse effects are fewer than
those associated with ergot therapy, triptans can still cause dizziness, feelings of strangeness, and
vertigo, so the patient should not drive while taking the drug. Medications are often only taken once
due to prolonged half-lives, but some may be repeated in 2 to 4 hours if the headache does not subside.
5. The nurse receives an order for a triptan for a patient diagnosed with cluster headaches. What drug would be indicated for this purpose? A) Almotriptan (Axert) B) Frovatriptan (Frova) C) Naratriptan (Amerge) D) Sumatriptan (Imitrex)
Ans: D
Feedback:
Sumatriptan, the first drug of this class, is used for the treatment of acute migraine attacks and for the
treatment of cluster headaches in adults. No other triptans are approved for treatment of cluster
headaches.
- Before administering an ergot drug to the patient for the first time, the nurse would assess the patient’s
currently prescribed medications for what drug?
A) Antidiabetic agents
B) Beta adrenergic blockers
C) Oral contraceptives
D) Selective serotonin reuptake inhibitors (SSRIs)
Ans: B
Feedback:
The concurrent use of beta blockers and ergot preparations increases the patient’s risk for peripheral
ischemia and gangrene. This combination should be avoided. There is no indication for concern with
the use of antidiabetic agents, SSRIs, and oral contraceptives with these drugs.
- The anatomy and physiology instructor is talking about pain sensations. What produces pain sensations
when stimulated by generating nerve impulses? (Select all that apply)
A) A-delta fibers
B) D-delta sensory nerves
C) Mu receptors
D) Sigma-receptors
E) C fibers
Ans: A, E
Feedback:
Two small-diameter sensory nerves, A-delta and C fibers, respond to stimulation by generating nerve
impulses that produce pain sensations. Large-diameter sensory nerves (i.e., A fibers) transmit
sensations associated with touch and temperature. Mu-receptors are primarily pain-blocking receptors;
sigma-receptors cause papillary dilation and may be responsible for the hallucinations, dysphoria, and
psychoses that can occur with narcotic use.
- A nurse is caring for a 6-year-old patient after surgery. The child has an order for meperidine
(Demerol) 1.8 mg/kg IM every 3 to 4 hour as needed for pain. The child weighs 30 kg and the
meperidine is available as 50 mg/mL. How many mL will the nurse administer per dose?
A) 1 mL
B) 1.8 mL
C) 0.8 mL
D) 1.08 mL
Ans: D
Feedback:
To calculate the correct amount to be administered, first multiply 1.8 mg times 30 kg (54 mg). Next
determine the volume in mL that 54 mg is equal to (50 mg: 1 mL as 54 mg: × mL). Solve forx (50x is
equal to 54 mg; 54 divided by 50 is equal to 1.08 mL).
- A patient with a migraine took a dose of a prescribed triptan, eletriptan (Relpax), and 1 hour later the
headache is still intense. The patient’s husband calls the clinic and asks the nurse what they should do.
What is an appropriate nursing response?
A) Tell her to lie down in a quiet cool room and just wait it out. It will subside.
B) She can take another dose of the drug 2 hours after the initial dose if the headache continues.
C) Give her a dose of an ergot drug if you have it. It will decrease the intensity of the pain.
D) Ibuprofen may increase the action of the triptan.
Ans: B
Feedback:
A patient taking eletriptan to relieve a migraine can take another dose in 2 hours if the headache is not
relieved. The combination of ergot drugs with triptans is not indicated because of the vasoconstriction
caused by both. The patient will not get relief by waiting it out. Ibuprofen is an anti-inflammatory that
does not affect the mechanism associated with migraines.
- The nurse is caring for a patient who is receiving an opioid analgesic. What are the nurse’s priority
assessments?
A) Pain intensity and blood glucose level
B) Level of consciousness and respiratory rate
C) Respiratory rate and electrolytes
D) Urine output and pain intensity
Ans: B
Feedback:
The nurse should assess respiratory rate and level of consciousness because respiratory depression and
sedation are adverse effects of opioid analgesics. Blood glucose levels, electrolytes, and urine output
are not priority assessments with opioid ingestion
- The nurse is caring for a patient experiencing postoperative pain. The physician orders 2.5 mg of
morphine IV every two hours. Morphine is supplied in 10 mg/mL vials. How many mL will the nurse
administer?
A) 0.25 mL
B) 0.5 mL
C) 1 mL
D) 2 mL
Ans: A
Feedback: 10 mg = 1 mL and a dose of 2.5 mg is ordered. 10 mg/1 mL: 2.5 mg/x Cross-multiply to yield 2.5 mg =
10x. Divide each side by 10 to learn the nurse should administer 0.25 mL
- A 72-year-old patient is admitted to the hospital for surgery. After the patient returns to the floor, the
patient’s daughter tells the nurse she is concerned that her mother will overdose on morphine because
she keeps pressing the button on her patient-controlled anesthesia (PCA) pump. What is the nurse’s
best response?
A) You should control how often she presses the button.
B) If she will follow the directions she was given, that will not happen.
C) The PCA device always provides the correct amount, so pressing the button is just for placebo
effect.
D) The device is preset, so your mother cannot get more than a specific amount.
Ans: D
Feedback:
A PCA system using morphine provides a baseline, constant infusion of morphine and gives the patient
control of the system to add bolus doses of morphine if the patient believes that pain is not being
controlled. The system prevents overdose by locking out extra doses until a specific period of time has
elapsed. The PCA is for the patient to control the analgesia, not for a family member to control it
because the patient will fall asleep when adequate pain control is reached. If the family keeps pushing
the button while the patient’s level of consciousness continues to decline, serious overdosage could
occur. Not following directions could result in inadequate pain management but not overdosage. The
button delivers small bolus dosages so it is not a placebo effect.
13. What drug might the nurse administer for both analgesic and antitussive effects? A) Codeine B) Aspirin C) Ibuprofen D) Acetaminophen
Ans: A
Feedback:
Codeine is a narcotic drug used for its analgesic and antitussive effects. Aspirin, ibuprofen, and acetaminophen do not have antitussive effects.
- As the nurse settles the patient into his room after returning from the post-anesthesia care unit (PACU),
the patient says he is in severe pain. The nurse checks the medical record and sees the patient has an
order for morphine 4 to 8 mg every 1 to 2 hour IV as needed for pain. The nurse sees this medication
has not been administered yet so the nurse administers 4 mg. After administering the drug, the PACU
nurse calls to say a dose of morphine was given and not documented. What drug will the nurse be
prepared to administer if the patient’s respiratory rate is depressed?
A) Naloxone hydrochloride tartrate (Narcan)
B) Butorphanol
C) Buprenorphine (Buprenex)
D) Nalbuphine hydrochloride (Nubain)
Ans: A
Feedback:
Naloxone is the drug of choice for treatment of opioid overdose. Butorphanol (INN) is amorphinantype
synthetic opioid analgesic that would not reverse the effects of an opioid. Buprenex
(buprenorphine hydrochloride) is a narcotic-agonist-antagonist and would suppress respirations further.
Nalbuphine is a synthetic opioid used commercially as an analgesic that would also depress
respirations.
- The nurse is providing patient teaching about a prescribed opioid analgesic. What is an important
teaching point related to a possible adverse effect of this drug?
A) Ataxia
B) Blurred vision
C) Hypotension
D) Dysrhythmias
Ans: C
Feedback:
Orthostatic hypotension is commonly seen in association with some narcotics. Ataxia, blurred vision,
and dysrhythmias are not commonly seen adverse effects of an opioid analgesic
- The nurse receives an order for morphine sulfate 8 mg IV every 1 hour as needed for pain. For which patient would the nurse need to question this order?
A) A 78-year-old with osteoarthritis
B) A 45-year-old, 1-day postoperative mastectomy
C) A 28-year-old with a fractured tibia
D) A 17-year-old, 1-day postoperative appendectomy
Ans: A
Feedback:
Older patients are more likely to experience the adverse effects associated with narcotics, including
central nervous system, gastrointestinal, and cardiovascular effects. Furthermore, a strong narcotic
analgesic would not be indicated for chronic osteoarthritis pain. For both of these reasons, the nurse
would question the large dosage of a narcotic. The other patients could appropriately receive morphine
8 mg unless they were smaller than average adults.
- The nurse is administering morphine to a trauma patient for acute pain. Before administering the
morphine, what common adverse effect should the nurse inform the patient about?
A) Paresthesia in lower extremities
B) Occipital headache
C) Increased intracranial pressure
D) Drowsiness
Ans: D
Feedback:
Common adverse effects include dizziness, drowsiness, and visual changes. Morphine does not
commonly cause paresthesia in the lower extremities, an occipital headache, or increased intracranial
pressure.
- The nurse administers a narcotic analgesic to the postoperative patient. What is the best way for the
nurse to evaluate response to the medication?
A) Observe the patient without her awareness.
B) Use a pain assessment tool before and 30 minutes after administration.
C) Assess vital signs.
D) Measure oxygen saturation.
Ans: B
Feedback:
A standard pain assessment tool should be used both pre- and post-analgesia. Observing the patient
when she is not aware you are watching, assessing vital signs, and measuring oxygen saturation may all
contribute useful data but it would not be the best means of determining pain response following
analgesic administration.
- A patient, 6 days postoperative, is being weaned off an opioid analgesic. The patient reports he is
getting no relief from the pain with the new non-opioid medication he is receiving. What might the
nurse suspect is causing this patient’s pain?
A) The patient needs a higher dose of the opioid analgesic.
B) The patient has become addicted to the opioid medication.
C) The patient has developed withdrawal syndrome.
D) The patient has developed a cross-hypersensitive reaction
Ans: C
Feedback:
Caution should be used in cases of physical dependence on a narcotic because a withdrawal syndrome
may be precipitated, the narcotic antagonistic properties can block the analgesic effect, and so intensify
the pain. It is important to differentiate between addiction and dependence because addiction generally
does not occur in patients receiving narcotics for medical reasons. There is no indication of a
hypersensitivity reaction. Giving a higher dose of the opioid would eliminate the progress made to date
on weaning the patient from the narcotic, so attempts should be made to avoid this intervention.
20. Which narcotic analgesics can the nurse administer to a child because she has an established pediatric dose? (Select all that apply.) A) Transdermal fentanyl B) Methadone C) Morphine D) Meperidine E) Hydrocodone
Ans: C, D, E
Feedback:
Narcotics that have an established pediatric dose include codeine, fentanyl (but not the transdermal
form), hydrocodone, meperidine, and morphine. Methadone is not recommended as an analgesic in
children.
- The home care nurse administers oral morphine to the patient with cancer pain. When will the nurse
expect this medication to reach peak activity?
A) 10 minutes
B) 30 minutes
C) 45 minutes
D) 60 minutes
Ans: D
Feedback:
With oral administration, peak activity occurs in about 60 minutes. The duration of action is 5 to 7
hours.
22. Before administering an opiate medication, what will the nurse assess? A) The patient’s weight B) The patient’s heart rate C) The patient’s respiratory rate D) The patient’s drug tolerance
Ans: C
Feedback:Check the rate, depth, and rhythm of respirations before each dose. If the patient’s heart rate is slower
than 12 beats per minute, delay or omit the dose and report to the physician. Weight would be assessed
before determining dosage. Heart rate would not be an essential assessment before administration. Drug
tolerance is assessed by monitoring patient’s response to the medication and could not be assessed
before administration.
- The nursing instructor asks the student nurse to explain the action of sumatriptan. What is the student’s
best response?
A) Vasoconstrictive on cranial blood vessels
B) Depresses pain response in the central nervous system
C) Vasodilation of peripheral blood vessels
D) Binds to acetylcholine receptors to prevent nerve transmission
Ans: A
Feedback:
Sumatriptan binds to serotonin receptors to cause vasoconstrictive effects on cranial blood vessels. The
other options are incorrect.
- The nurse administers pentazocine cautiously to what population?
A) Patients with known GI disease
B) Patients with known heart disease
C) Patients with known urinary disease
D) Patients with known respiratory disease
Ans: B
Feedback:
Pentazocine must be administered cautiously to patients with known heart disease because the drug
may cause cardiac stimulation including arrhythmias, hypertension, and increased myocardial oxygen
consumption, which could lead to angina, myocardial infarction, or congestive heart failure. No
indication exists that it must be given cautiously to patients with gastrointestinal, urinary, or respiratory
diseases.
- Narcotic agonists-antagonists have what function? (Select all that apply.)
A) Relief of moderate-to-severe pain
B) Adjunctive therapies to nonsteroidal anti-inflammatory drugs (NSAIDs)
C) Relief of pain during labor and delivery
D) Relief of orthopedic pain
E) Adjuncts to general anesthesia
Ans: A, C, E
Feedback:
These drugs have three functions: (1) relief of moderate-to-severe pain, (2) adjuncts to general
anesthesia, and (3) relief of pain during labor and delivery. Adjunctive therapies to NSAIDs or
specificity for orthopedic pain are not functions of this classification of medication
- You are caring for a patient taking pentazocine (Talwin). What would be an appropriate nursing
diagnosis for this patients care plan?
A) Fluid volume deficit related to diarrhea caused by medication
B) Risk for pain related to administration of medication
C) Monitor timing of analgesic doses.
D) Impaired gas exchange related to respiratory depression
Ans: D
Feedback:
Nursing diagnosis may include impaired gas exchange related to respiratory depression. The drug is
more likely to cause constipation due to slowing of the GI tract instead of diarrhea, so that fluid volume
deficit would not be appropriate. Monitoring timing of analgesic doses is an intervention and not a
nursing diagnosis. If the patient is receiving pentazocine that would indicate he is experiencing pain
and is not just at risk for pain, and that the pain is not caused by the drug. The drug is given to reduce
the pain so this diagnosis is incorrect.
27. When evaluating the effects of narcotic agonist-antagonists on a patient, what adverse effects would the nurse monitor for? A) Hypertension B) Bleeding C) Suppressed bone marrow function D) Increased pulse pressure
Ans: A
Feedback:
Monitor for adverse effects (e.g., central nervous system changes, gastrointestinal (GI) depression,
respiratory depression, arrhythmias, hypertension). Bleeding, bone marrow suppression, and increased
pulse pressure are not normally seen with these drugs
- What is the nurse’s priority assessment when administering narcotics to older adults? (Select all that
apply.)
A) Central nervous system (CNS) effects
B) Gastrointestinal effects
C) Cardiovascular effects
D) Urinary effects
E) Developmental effects
Ans: A, B, C
Feedback:
Older patients are more likely to experience the adverse effects associated with these drugs, including
central nervous system, gastrointestinal (GI), and cardiovascular effects. Urinary and developmental
effects are not areas of high concern.
29. By what route will the nurse administer methylnaltrexone (Relistor)? A) IV B) Subcutaneously C) Intranasally D) Orally
Ans: B
Feedback:
Relistor is only given by subcutaneous injection once each day.
- According to the Gate Control Theory, what interventions by the nurse could help to block pain
impulses?
A) Administration of opioid medications
B) Administration of narcotic agonist-antagonists
C) Back massage
D) Acupuncture
Ans: C
Feedback:
According to the gate control theory, the transmission of these impulses can be modulated or adjusted
all along these tracts. All along the spinal cord, interneurons can act as gates by blocking the ascending
transmission of pain impulses. It is thought that the gates can be closed by stimulation of the larger A
fibers and by descending impulses coming down the spinal cord from higher levels in such areas as the
cerebral cortex, the limbic system, and the reticular activating system. Administration of medications
does not use the Gate Control Theory. Acupuncture uses the Gate Control Theory but is not performed
by the nurse
- The patient in labor receives morphine every 2 hours to manage labor pain. After 22 hours of labor the
woman delivers a baby boy. What is the nurse’s priority action related to the newborn?
A) Monitor for opioid effects.
B) Administer naloxone.
C) Monitor for withdrawal syndrome.
D) Assess for congenital anomaly.
Ans: A
Feedback: Morphine, meperidine, and oxymorphone are often used for analgesia during labor. The mother should
be monitored closely for adverse reactions, and, if the drug is used during a prolonged labor, the
newborn infant should be monitored for opioid effects. Naloxone would only be given if the newborn
displays opioid effects. Withdrawal syndrome would not be seen with less than 24 hours of use. Every
newborn is assessed for congenital anomalies but this would not be related to administration of
morphine to the mother and so would not be the highest priority.
32. What medication would the nurse administer to the patient in severe pain? A) Codeine B) Hydrocodone C) Hydromorphone D) Opium
Ans: C
Feedback:
Hydromorphone is indicated for moderate-to-severe pain. Codeine is indicated for mild-to-moderate
pain, hydrocodone is indicated for moderate pain, and opium is indicated for treatment of diarrhea and
relief of moderate pain.
- The patient is brought to the emergency department in respiratory arrest after overdosing on heroin.
The person accompanying the patient says he has been using heroin for years. After being administered
one dose of a narcotic antagonist, the patient begins to breathe spontaneously but remains
nonresponsive to stimuli so another dose of narcotic antagonist is ordered. What symptoms would
indicate the patient is experiencing acute narcotic abstinence syndrome? (Select all that apply.)
A) Tachycardia
B) Hypertension
C) Vomiting
D) Confusion
E) Sedation
Ans: A, B, C
Feedback:
The most common adverse effect is an acute narcotic abstinence syndrome that is characterized by nausea, vomiting, sweating, tachycardia, hypertension, tremulousness, and feelings of anxiety.
Confusion and sedation are not associated with acute narcotic abstinence syndrome.
34. What order for naloxone would be appropriate for the nurse to administer for reversal of opioid effects? A) 1 mg IV repeat every 2 to 3 minutes B) 5 mg IV repeat every 5 minutes C) 0.1 mg IV repeat every 2 to 3 minutes D) 0.4 mg IV repeat every 3 minutes
Ans: C
Feedback:
0.1 to 0.2 mg is given IV and then repeated every 2 to 3 minutes for reversal of opioid effects. If the
patient has overdosed on opioids the dose would be 0.4 to 2 mg every 2 to 3 minutes. The other options
are incorrect.
