E3 Questions Flashcards
What is the antidote for acetaminophen overdose?
Acetylcysteine (Mucomyst)
RJ, a 70-year-old male, underwent abdominal surgery for resection of his colon. His surgeon prescribed morphine 10 mg q 3 to 4 hours PRN. RJ has not asked for pain medication. One day post-op you note he is restless, grimacing, and guarding his abdomen. He has refused to use the inspirometer or to cough/deep breathe. His vital signs show increased heart rate and Bp.
What is the significance of the signs & symptoms RJ is presenting?
Restless, grimacing, and guarding
Refused to use the inspirometer
Refused to cough/deep breathe
Increased heart rate and Bp
(RJ) What patient education might you offer in order to encourage the patient to use the ordered pain medication?
Addiction risk: actual vs. myth
Therapeutic levels of medication
Positive relationship between healing time and adequate pain control
R.J. would be more comfortable and able to participate in the activities that are necessary to maintain a healthy state, such as deep breathing and coughing
Provide analgesic medication 30 minutes before encouraging R.J. to use the inspirometer
Common opioid SE
Nausea and vomiting (particularly in ambulatory patients)
Generalized itching is common
without a rash and not associated with allergy or intolerance
Constipation
Orthostatic hypotension
Sedation
Respiratory depression
Urinary retention
Opioid administration nursing assessments/interventions related to side effects
Monitor vital signs, sedation level, UO, pain level, bowel sounds, GI upset;
Use safety measures: siderails up, call light in reach, ambulate with assist
Stool softener
Monitor mental status, especially elderly!
Your patient education has been effective! RJ has been requesting morphine every 3-4 hours and his pain level has been effectively managed. Day 3 post-op, the surgeon discontinues the morphine and orders hydrocodone bitartrate and acetaminophen (Norco 5/325) one or two every 4-6 hours PRN pain.
Why was there a pain medication order change?
Opioid orders are changed to prevent opioid dependency. By the third to the fifth day, pain should have lessened, and a less potent opioid or mixed drugs are usually prescribed
When are opioid analgesics contraindicated and why?
- Patients with head injuries – may cause an increase in ICP
- Patients with shock – may cause hypotension
- Caution in patients with asthma – opiates decrease respiratory drive while increasing airway resistance
- Caution in patients with renal failure
- Contraindicated vs caution: Asthma and renal failure, can still be used with caution; need labs, assessment, etc.
What medication(s) can be used for morphine overdose?
Naloxone (Narcan) is an opioid antagonist used to reverse opioid overdose
Opioid antagonists
Use
Antidote for opiate overdoses
Reverse effects of opiates, including respiratory depression, sedation, hypotension
Respiratory distress, respiratory depression
Opioid addiction: Naltrexone hydrochloride (ReVia)

A patient is admitted to the surgical unit after undergoing an exploratory laparotomy. Morphine sulfate has been ordered for pain control. Before administering morphine, it is most important for the nurse to assess the patient for
a. Respiratory disease
b. Hypothermia
c. Allergy to penicillin
d. Hypertension
Answer: respiratory disease
Rationale: Contraindications for morphine include severe respiratory disorders, increased intracranial pressure, and hypotension, inflammatory bowel disease
A patient’s pain medication is changed from morphine sulfate to hydromorphone (Dilaudid). Which statement regarding hydromorphone (Dilaudid) does the nurse identify as being true?
a. Hydromorphone (Dilaudid) must be administered orally.
b. Hypertension is a common side effect.
c. Physical dependence does not occur with hydromorphone (Dilaudid) therapy.
d. Hydromorphone (Dilaudid) is more potent than morphine.
D. Hydromorphone (Dilaudid) is a semisynthetic opioid similar to morphine. The analgesic effect is approximately six times more potent than morphine. Patient safety! Check your dose!
The nurse assesses a patient receiving morphine via a PCA pump. The patient has a respiratory rate of 8 breaths/min. The nurse anticipates administration of which of the following drugs?
a. Naloxone (Narcan)
b. Sumatriptan (Imitrex)
c. Nalbuphine HCl (Nubain)
d. Hydromorphone (Dilaudid)
A. Naloxone (Narcan)
Naloxone is a opiate antagonist and an antidote for opioid analgesic overdoses. Sumatriptan (Imitrex) is used for the treatment of migraine headaches; nalbuphine HCl (Nubain) and hydromorphone are opiates.
The nurse identifies which of the following as a common side effect/adverse effect of morphine therapy?
a. Diarrhea
b. Hypertension
c. Urinary retention
d. Tachypnea
C. Urinary Retention
Urinary retention, constipation, hypotension, and bradypnea are common side effects of morphine. Diarrhea, hypertension, and tachypnea are not common side effects.
A patient received morphine sulfate for severe pain. The nurse assesses the patient 20 minutes later. What is the best indication that the medication has been effective?
a. Patient verbalizes pain relief.
b. Patient has an increase in heart rate.
c. Patient is resting.
d. Patient has an increase in blood pressure.
A. patient verbalizes pain relief
Best source of evaluation of pain is the patient
A patient who has recurrent migraine headaches is prescribed sumatriptan [Imitrex]. Which aspect of this patient’s history is of concern when taking this drug?
a. Diabetes
b. Asthma
c. Renal Disease
d. Coronary Artery Disease
D. Coronary artery disease
Serotonin receptor agonists can cause vasoconstriction and coronary vasospasm and should not be given to patients with coronary artery disease, current symptoms of angina, or uncontrolled hypertension. There is no contraindication for asthma, diabetes, or renal disease.
A prescriber orders sumatriptan [Imitrex] for a patient for a migraine headache. Before administration of this drug, it would be most important for the nurse to assess whether the patient:
a. has taken ergotamine in the past 24 hours.
b. has taken acetaminophen in the past 3 hours.
c. has a family history of migraines.
d. is allergic to sulfa compounds.
A. has taken ergotamine in the past 24 hr
Sumatriptan, other triptans, and ergot alkaloids all cause vasoconstriction and should not be combined, or excessive and prolonged vasospasm could result. Sumatriptan should not be used within 24 hours of an ergot derivative and another triptan. A family history is important, but it is not vital assessment data as it relates to this scenario. Acetaminophen has no drug-to-drug interaction with sumatriptan. Sulfa is not a component of sumatriptan and therefore is not relevant.
A patient with schizophrenia has been taking an antipsychotic drug for several days. The nurse enters the patient’s room to administer a dose of haloperidol [Haldol] and finds the patient having facial spasms. The patient’s head is thrust back, and the patient is unable to speak. What will the nurse do?
a. Discuss increasing the haloperidol dose with the provider.
b. Request an order to give levodopa.
c. Administer the haloperidol as ordered.
d. Request an order to give diphenhydramine.
D. Request an order to give diphenhydramine
An early reaction to antipsychotic drugs is acute dystonia. Initial treatment consists of an anticholinergic medication, such as diphenhydramine. Administering more antipsychotic medication would increase the symptoms and could be life threatening. Levodopa is not given for extrapyramidal symptoms, because it could counteract the beneficial effects of antipsychotic treatment.
Why do patients who take antipsychotic drugs often take medications also used for Parkinson symptoms?
Many patients who take antipsychotic drugs experience extrapyramidal syndrome (EPS), a chronic neurologic disorder that affects the extrapyramidal motor track, resulting in tremors, masklike facies, rigidity, and shuffling gait. These symptoms result from dopamine being blocked.
Terms to know: Dystonia, parkinsonism, akathisia, tardive dyskinesia
What medications can be used to treat the symptoms of EPS? Specifically:
Acute dystonia
Akathisia
Tardive dyskinesia
Acute dystonia: Benztropine (Cogentin) – AntiParkinson’s drug , Diphenhydramine
Parkinsonism: Beztropine (Cogentin), Diphenhydramine, Amantadine
Akathisia: beta blocker (propranolol), benzodiazepine lorazepam (Ativan), Anticholinergic drugs
Tardive Dyskinesia (TD): Stop the antipsychotic, switch to different med (SGA with low risk of TD), Benzodiazepine, Valbenazine – newly approved for TD
What is Neuroleptic Malignant Syndrome (NMS)?
What are symptoms?
How is it treated?
Rare, potentially fatal condition, Neuroleptic malignant syndrome is characterized by “lead pipe” rigidity, sudden high fever, and autonomic instability
Symptoms
Altered mental status, seizures
Muscle rigidity, sudden high fever
BP fluctuations, tachycardia, dysrhythmias
Rhabdomyolysis, acute renal failure
Respiratory failure, coma
Treatment: Immediate withdrawal of antipsychotics
Supportive measures: Hydration – IV fluids,
Hypothermic blankets
- Antipyretics, Benzodiazepines
Dantrolene (Dantrium):
Used to relax muscles and reduce heat production
Bromocriptine (Parlodel):
Dopamine receptor agonist, relieves CNS toxicity
FGA have which of the following potential side effects? (select all that apply)
a. Dry mouth
b. Urinary urgency
c. Agranulocytosis
d. Prolonged QT Interval
e. Hypertension
f. Hyperactivity
Dry mouth – yes! r/t anticholinergic effect
Urinary urgency – no…urinary retention
Agranulocytosis – yes! Monitor CBC, s&sx of infection
Prolonged QT Interval – yes! EKG & K+ levels required before starting and during treatment with: chlorpromazine (Thorazine), haloperidol (Haldol), and thioridazine (Melleril)
Hypertension – no…postural hypotension
Hyperactivity – no …sedation, especially initially
FGA’s more side effects
Sexual dysfunction – major reason for discontinuation; may switch to SGA
Increased Prolactin levels
May increase (not cause) growth of cancers – contraindicated with cancers affected by prolactin
Gynecomastia – men and women
Irregular menstrual cycle
Seizures
Reduces seizure threshold
Seizure medication adjustment may be needed
A patient with schizophrenia has been taking an oral FGA for 1 week. The patient has been taking the drug daily in two divided doses. The individual complains of daytime drowsiness. The patient’s family reports a decrease in the person’s hostility and anxiety but states that the patient remains antisocial with disordered thinking. What will the nurse tell the patient and the family?
a. Intramuscular dosing may be needed
b. Some symptoms take months to improve
c. An increased dose of the drug may be needed
d. The entire dose may be taken at bedtime
B. some symptoms take months to improve
When patients begin therapy with antipsychotic medications, some symptoms resolve sooner than others. During the first week, agitation, hostility, anxiety, and tension may resolve, but other symptoms may take several months to improve. It is not necessary to increase the dose in the first week. IM dosing is indicated for patients with severe, acute schizophrenia and for long-term maintenance. Sedation is normal, and once an effective dose has been determined, the entire dose can be taken at bedtime, but not in the initial days of therapy.
Why are liquids the preferred oral route for antipsychotics?
Absorption rate is faster with liquid and to avoid cheeking pills
What else are benzodiazepines used for? (Klonopin + Restoril) What is given for an overdose?
Klonopin - Seizures
Restoril - Insomnia
Overdose: Flumazenil (romazicon)
