Which antihistamine would be just fine for a kid with allergic rhinitis and itchy watery eyes, who can't sleep because his allergies are bothering him so much? How about for the allergic kid whose itchy, puffy eyes have been bothering him all spring making his school days miserable?
- A first gen is great for someone with allergies that cannot sleep or needs to take something right before bed. - A second generation is great for someone who needs to take it at or before school and needs to stay alert all day.
Be sure that you recognize the symptoms of anaphylaxis. Can antihistamines be used to treat anaphylaxis?
- Anaphylaxis is when you bronchoconstrict, have severe hypotension, and edema of the glottis. - You can also go into cardiac arrest. - Antihistamines CAN NOT be used for these because the reaction is not fast or - Use epinephrine.
What drugs should not be combined with first-generation antihistamines?
- Anything that also depresses the CNS. - Can include alcohol, benzodiazepines, and barbituates.
Is diphenhydramine (Benadryl) a first gen antihistamine? Promethazine? Hydroxyzine? Clemastine? Cetirizine? Fexofenadine? Loratidine?

A child's mother has inadvertently overdosed her on antihistamines by using multiple OTC cold preps? What does toxicity look like? Is there an antidote we can give this child to rid the body of the medication? What do we do?
- It's rare to do so, but It's actually going to be the opposite of CNS depression. - It's going to be agitation, jittery, hot, dry, red skin. Anticholinergic effects. - There is NO antidote. You just have to treat the symptoms (IV fluids, something for anxiety).
Second-Generation H1 Antagonists
- Less sedation (dont bass the BBB) - Actions with alcohol and other CNS depressants are low -Do not have anticholinergic effects -Most need prescription and are pricey
Recall those anticholinergic effects, they are a prominent set of side effects of the drugs in this chapter.
- Occur with first generations. Can't see, can't spit, can't pee, can't ____. Blurry vision, dry mouth, constipation.
First-generation H1 antagonists
- Sedation can be a problem - CNS depression very common with the ethanolamines and less sedation in alkylamines - Cause anticholinergic effects
How do the drugs in this chapter work? For which conditions are they useful?
- These drugs are histamine antagonists. - They cover the H1 receptors, and SLOWLY reverse/help an allergic reaction. - They reduce itching and pain, mild allergies, and in some cases motion sickness. - They are useful for mild allergy problems/attacks.
What are the local effects of histamine (think about blood vessels, nerve endings) ? In which cells is histamines stored?
- When certain immune cells burst, packets of histamines come out. - Capillaries start to leak which causes swelling and edema, places constrict, places vasodilate, and you get pain, and itching.
What is a generalization that can be made about all "first generation" antihistamines? Along these lines, what is the important difference between first and second generation antihistamines?
-All first generation antihistamines cause CNS depression, so most importantly, drowsiness (can cause depression, confusion, etc.). -2nd gen. Less sedation. Synergism with alcohol and other CNS depressants is low. Have no anticholinergic actions.

H1 Antagonists Therapeutic uses
-Mild allergy -Severe allergy (Adjunct only, benefits may be limited) -Motion sickness (Promethazine, dimenhydrinate) -Insomnia -Common cold (May decrease rhinorrhea through anticholinergic properties, not H1 blockade)
H1 Antagonists Pharmacologic effects:
-Peripheral effects (Reduce localized flushing, Reduce itching and pain) -Effects on the CNS (CNS depression, 2nd gen depression nothing) -Overdose: CNS stimulation, Convulsions, Very young children especially sensitive to CNS stimulation
Histamine Distribution
-Present in practically all tissues -Especially high in skin, lungs, and GI tract -Low content in plasma

4. sympathomimetics Response Feedback: This is the function of this class of drugs that stimulates the sympathetic nervous system, opening the airway.
The nurse is caring for a patient treated with flumazenil (Anexate) for benzodiazepine toxicity. After administering flumazenil what will the nurse carefully assess for? A) Agitation, confusion, and seizures B) Cerebral hemorrhage and dystonia C) Hypertension and renal insufficiency D) Hypotension, dysrhythmias & cardiac arrest
A ~ Administration of flumazenil blocks the action of benzodiazepines. If the patient has been taking these medications for an extended period of time, the blockage of the drugs effects could precipitate an acute benzodiazepine withdrawal syndrome with symptoms including agitation, confusion, and seizures. Anexate does not cause cerebral hemorrhage and dystonia, hypertension, renal insufficiency, hypotension, dysrhythmias, and cardiac arrest.
Extrapyramidal symptoms are a side effect of perphenazine (Trilafon). The nurse should assess and observe for which sign of akathisia? a. Restlessness and constant moving about b. Facial grimacing c. Chewing motion d. Involuntary eye movement
A ~ Akathisia is described as restless, agitated movement.
The nurse administers promethazine (Phenergan) to the patient before sending the patient to the preoperative holding area. What is the rationale for administration of this drug? A) Sedation B) Oral secretions C) Hypotension and bradycardia D) Confusion
A ~ Antihistamines (promethazine, diphenhydramine [Benadryl]) can be very sedating in some people. They are used as preoperative medications and postoperatively to decrease the need for narcotics. Promethazine is not given for hypotension, bradycardia, confusion, or oral secretions.
A patient explains to a nurse that he had been taking amitriptyline (Elavil) for depression and that his physician changed his medication to clomipramine (Anafranil). The patient is confused and does not understand why his medication was changed. The nurses best response to the patient would be what? A) These drugs are similar but some patients respond better to one drug than another. B) Did you take the amitriptyline like you should have? C) Maybe the old medicine wasnt working anymore. D) Clomipramine is newer and will be much better for you.
A ~ Because all tricyclic antidepressants (TCAs) are similarly effective, the choice of which TCA depends on individual response to the drug and tolerance of adverse effects. A patient who does not respond to one TCA may respond to another drug from this class. In addition, the nurse might inform the physician of the patients question so the physician can explain his or her rationale for changing medications. By asking the patient if he took the medication as prescribed, the nurse is insinuating that he may not have and could damage the trusting nursepatient relationship. The nurse has no basis for commenting that the medication might not be working or that another drug would work better.
Obsessive-compulsive disorder (OCD) is a disorder that remains under investigation as to its actual neurophysiology. What tricyclic antidepressant is now approved by the Food and Drug Administration to treat OCD? A) Clomipramine B) Imipramine C) Nortriptyline D) Amitriptyline
A ~ Clomipramine is now also approved for use in the treatment of OCD. Imipramine, nortriptyline, and amitriptyline are not approved for use in treating OCD.
A 75-year-old patient is brought to the emergency department by his family. The family relates that the patient is complaining of confusion, seizures, and abnormal perception of movement. The nurse reviews all of the medication bottles found in the house and suspects the patient overdosed on what medication? A) Benzodiazepine B) Antihypertensive C) Sedative D) Analgesic
A ~ Common manifestations of benzodiazepine toxicity include increased anxiety, psychomotor agitation, insomnia, irritability, headache, tremor, and palpitations. Less common but more serious manifestations include confusion, abnormal perception of movement, depersonalization, psychosis, and seizures. These symptoms are not found in association with options B, C, or D.
A client is taking an anxiolytic agent secondary to grief-related anxiety. The client questions the nurse about abruptly discontinuing these agents. The nurses response is based on the knowledge that, when discontinuing these medications: a. the dosage must be tapered to avoid withdrawal. b. the client must be evaluated for hyperglycemia. c. hangover syndrome must be planned for. d. blood levels must be monitored.
A ~ Discontinuing anxiolytic agents abruptly may lead to withdrawal symptoms.
A client is ordered to receive chlordiazepoxide (Librium) for severe anxiety. The nurse monitors for which symptoms of severe anxiety or panic attack? a. Dyspnea and heart palpitations b. Trembling, shaking, and gastrointestinal upset c. Dizziness and anorexia d. Drowsiness and blurred vision
A ~ Dyspnea and heart palpitations are symptoms of severe anxiety; also experienced is chest pain, dizziness, or faintness.
A patient is admitted to the unit with obsessive-compulsive disorder (OCD). What drug might the nurse administer that has been found to be effective for treating OCD? A) Fluvoxamine B) Phenelzine C) Desipramine D) Amitriptyline
A ~ Fluvoxamine is indicated for the treatment of OCD and is classified as a selective serotonin reuptake inhibitor (SSRI). SSRIs are indicated for the treatment of depression, OCD, panic attacks, bulimia, premenstrual dysphoria disorder, posttraumatic stress disorder, social phobias, and social anxiety disorders. Phenelzine is indicated for depression not responsive to other agents. Desipramine and amitriptyline are tricyclic antidepressants indicated for treatment of depression especially if accompanied by anxiety or sleep disturbances.
The nurse is caring for a patient in a state of hypnosis, which means the patient is in what state? A) A state of extreme sedation in which the person no longer senses or reacts to incoming stimuli. B) A state of tranquility in which the person can be made to do whatever is suggested by others. C) A feeling of tension, nervousness, apprehension, or fear with high levels of awareness. D) A state in which the brain is no longer sending out signals to the body.
A ~ Hypnosis is an extreme state of sedation in which the person no longer senses or reacts to incoming stimuli. A state of tranquility is produced through minor tranquilizers by decreasing anxiety. Anxiety is a feeling of tension, nervousness, apprehension, or fear. Sedation is the loss of awareness and reaction to environmental stimuli, which may lead to drowsiness. The state of suggestibility often seen in television programs is not an appropriate definition of hypnosis. If the brain stopped sending signals, the patient would stop breathing and death would follow.
The client has been placed on Ativan. The nurse is planning a client instructional session. Which herbal preparation should the nurse emphasize that the client avoid taking with Ativan? a. Kava kava b. St. Johns wort c. Ginseng d. Ginger
A ~ Kava kava in combination with Ativan will increase the sedation effects of the Ativan.
A patient diagnosed with type 1 diabetes mellitus is receiving insulin. The physician has prescribed a monoamine oxidase inhibitor (MAOI) to treat this patients depression. What interaction will the nurse assess for with this drug combination? A) Increased risk of hypoglycemia B) Increased risk of hyperglycemia C) Increase in appetite D) Increased total cholesterol
A ~ MAOIs can cause an additive hypoglycemic effect if taken with insulin or oral diabetic agents. This patient would have to be monitored closely and appropriate dosage adjustments made; he should be taught the importance of more frequent blood sugar monitoring. The drug combination in this question would not cause an increase in appetite or increased total cholesterol.
The patient presents to the emergency department with a headache in the back of the head, palpitations, neck stiffness, nausea, vomiting, sweating, dilated pupils, tachycardia, and chest pain. Blood pressure measures 180/124 and heart rate is 168 beats per minute. The spouse says the only medication he takes is something for depression but she does not know the name of the drug and the patient is also unable to supply the name. What classification of antidepressant does the nurse suspect this patient is taking? A) Monoamine oxidase inhibitors (MAOIs) B) Selective serotonin reuptake inhibitors (SSRIs) C) Tricyclic antidepressants (TCAs) D) Antianxiety antidepressants
A ~ MAOIs have several serious adverse effects that can be fatal. This patients symptoms indicate fatal hypertensive crisis characterized by occipital headache, palpitations, neck stiffness, nausea, vomiting, sweating, dilated pupils, photophobia, tachycardia, and chest pain. It may progress to intracranial bleeding and fatal stroke. SSRIs and TCAs are not associated with these particular symptoms. Antianxiety antidepressants are not a classification of antidepressants.
The nurse is caring for a newborn who was delivered from a woman who took benzodiazepines for anxiety during the last 2 months of her pregnancy after her husband was killed in war. What will the nurse assess for in this newborn? A) Newborn withdrawal syndrome B) Hepatic dysfunction C) Failure to thrive D) Learning deficiencies
A ~ Neonatal withdrawal syndrome may result in a baby born to a mother who was taking benzodiazepines in the final weeks of pregnancy. The neonate may be given very small doses of benzodiazepines that are withdrawn gradually to prevent symptoms. Hepatic dysfunction in the neonate is not associated with use of benzodiazepines. Failure to thrive and learning deficiencies would be long-term problems and are not assessed during the neonatal period.
A patient has been taking Prozac (fluoxetine) for the past 3 years for depression. She is seeing her gynecologist for premenopausal symptoms and during the interview with the nurse she says that she would like to try Sarafem because her friend is taking it and she says it works great. The nurses best response is what? A) Sarafem and Prozac are different brand names for the same generic medication. B) Before changing drugs it is important to consider how well you responded to Prozac. C) You cannot take both drugs at the same time so it will be important to decide which is best. D) When taking both of these drugs, it is best to take one in the morning and one at night.
A ~ Prozac and Sarafem are different brand names for fluoxetine, so there is no benefit in changing the patients medication regimen and, if taken together, would result in a drug overdose. The other three responses are incorrect or inappropriate because they do not recognize that both drugs are the same.
The nurse is caring for an older adult in the long-term care facility who has begun to display signs of anxiety and insomnia. What is the priority nursing action? A) Assess the patient for physical problems. B) Call the provider and request an antianxiety drug order. C) Increase the patients social time, encouraging interaction with others. D) Suggest the family visit more often to reduce the residents stress level.
A ~ The patient should be screened for physical problems, neurological deterioration, or depression, which could contribute to the insomnia or anxiety. Only after physical problems are ruled out would the nurse consider nondrug measures such as increased socialization with other residents or family members. If nothing else is effective, pharmacological intervention may be necessary.
The nurse assesses the patient who had an abrupt withdrawal of benzodiazepines for withdrawal syndrome and would recognize what symptoms as part of the syndrome? (SATA) A) Headache B) Nightmares C) Malaise D) Bradycardia E) Hypotension
A, B, C ~ Abrupt cessation of benzodiazepines may lead to a withdrawal syndrome characterized by nausea, headache, vertigo, malaise, and nightmares. Withdrawal symptoms may be caused by the abrupt separation of benzodiazepine molecules from their receptor sites and the resulting acute decrease in gamma-aminobutyric acid (GABA) neurotransmission. Because GABA is an inhibitory neurotransmitter, less GABA may produce a less inhibited central nervous system (CNS) and therefore symptoms of hyperarousal or CNS stimulation. The nurse would not categorize hypotension or bradycardia as indicating benzodiazepine withdrawal.
The nurse is caring for a patient who received a new diagnosis of cancer. The patient exhibits signs of a sympathetic stress reaction. What signs and symptoms will the nurse assess in this patient consistent with an acute reaction to stress? (SATA) A) Profuse sweating B) Fast heart rate C) Rapid breathing D) Hypotension E) Inability to interact with others
A, B, C ~ Anxiety is often accompanied by signs and symptoms of the sympathetic stress reaction that may include sweating, fast heart rate, rapid breathing, and elevated blood pressure. Chronically anxious people may be afraid to interact with other people but this is not usually seen in an acute stress reaction.
The nurse interviews the family of a patient hospitalized with severe depression who is prescribed a tricyclic antidepressant. What assessment data are important in planning this patients plan of care? (SATA) A) Recent suicide attempts B) Gastrointestinal (GI) obstruction C) Affect D) Physical pain E) Personal responsibilities
A, B, C ~ When caring for a patient with a diagnosis of depression it is always important for the nurse to assess for recent suicide attempts, suicidal ideation, and any suicidal plans. After starting the medication, as the patient begins to feel better, risk of suicide increases, so ongoing assessment is essential to the patients safety. Other assessments include allergies, liver and kidney function, glaucoma, benign prostatic hypertrophy, cardiac dysfunction, GI obstruction, surgery, or recent myocardial infarction, all of which could be exacerbated by the effects of the drug. Assess history of psychiatric problems, or myelography within the past 24 hours or in the next 48 hours, or is taking a monoamine oxidase inhibitor to avoid potentially serious adverse reactions. Physical pain and personal responsibilities may be assessed but are not priority assessments unless indicated by other diagnoses.
The nurse is teaching a class for nurses working in prenatal clinics about the danger associated with use of benzodiazepines during pregnancy and explains that what fetal anomalies result from maternal use of benzodiazepines during the first trimester of pregnancy? (SATA) A) Cleft lip or palate B) Inguinal hernia C) Cardiac defects D) Microencephaly E) Gastroschises
A, B, C, D ~ Benzodiazepines are contraindicated in pregnancy because a predictable syndrome of cleft lip or palate, inguinal hernia, cardiac defects, microcephaly, or pyloric stenosis occurs when they are taken in the first trimester. Gastroschises, when the abdominal organs are found outside the abdominal cavity, is not associated with use of benzodiazepine use in the first trimester.
What reasons can the nurse give for why barbiturates are no longer considered the mainstay for treatment of anxiety? (SATA) A) Adverse effects are more severe. B) There is an increased risk of physical tolerance. C) There is an increased risk of psychological dependence. D) The most common adverse effects are related to cardiac arrhythmias. E) Hypersensitivity reactions can sometimes be fatal.
A, B, C, E ~ The adverse effects caused by barbiturates are more severe than those associated with other, newer sedatives/hypnotics. For this reason, barbiturates are no longer considered the mainstay for the treatment of anxiety. In addition, the development of physical tolerance and psychological dependence is more likely with the barbiturates than with other anxiolytics. The most common adverse effects are related to central nervous system (CNS) depression. Hypersensitivity reactions to barbiturates are sometimes fatal.
Which medications have an effect on the RAAS (Renin-Agiotensin) system? A. "sartan" B. -"olol" C.-"zosin" D.-"pril" E. "nitro"---- F. Eplerenone G. -"dipine"
A, B, D, F
Nitroprusside: Mark all that apply A. is given for hypertensive crisis for b/p greater than 180/120 B. is given to increase heart rate C. may be given slow intravenous push D. may have synergistic effect of hypotension with concurrent use of Ca+ channel blockes E. is the drug of choice in the maternity ward for hypertension for 160/98 F. needs to be placed on IV pump and titrated to acheive a drop in blood pressure
A,D,F
A client with myasthenia gravis and his family are receiving instructions from the nurse. The nurse teaches the client that insufficient dosing of cholinesterase inhibitor may result in myasthenia crisis. The client is taught about which signs and symptoms of myasthenia crisis? a. Muscle weakness; difficulty in breathing and swallowing b. Increased salivation and sweating c. Muscle weakness and increased salivation d. Decreased muscle strength in the lower extremities
A.Muscle weakness; difficulty in breathing and swallowing Response Feedback: These are the major signs of myasthenia gravis, which may be undertreated with insufficient dosing of the medication. Increased salivation is related to cholinergic crisis.

The nurse determines that the teaching plan for a client prescribed sertraliine (Zoloft) has been effective when the client makes which statement? 1. "I should not decrease my sodium or water intake." 2. "The drug can be taken concurrently with the phenelzine (Nardil) that I'm taking." 3. "It may take up to a month for the drug to reach full therapeutic effect and I'm feeling better." 4. "There are no other drugs I need to worry about, Zoloft does not react with them."
Answer Feedback: SSRI antidepressant drugs such as sertraline (Zoloft) may not have full effects for a month or longer but some improvement in mood and depression should be noticeable after beginning therapy. Options 1,2, and 4 are incorrect. Sodium and fluid intake is a concern with lithium but does not adversely affect the SSRI's. The SSRIs should not be used concurrently with MAOI's because of an increased risk for hypertensive crisis. They also have many interactions with other drugs. Response Feedback: SSRI antidepressant drugs such as sertraline (Zoloft) may not have full effects for a month or longer but some improvement in mood and depression should be noticeable after beginning therapy.
The mental health nursing instructor is talking with the class about depression. What deficiency does the instructor explain will result in depression? A) Epinephrine, norepinephrine, and acetylcholine B) Norepinephrine, dopamine, and serotonin C) Acetylcholine, gamma-aminobutyric acid, and serotonin D) Gamma-aminobutyric acid, dopamine, and epinephrine
B ~ A current hypothesis regarding the cause of depression is a deficiency of norepinephrine, dopamine, or serotonin, which are all biogenic amines, in key areas of the brain. Acetylcholine is a neurotransmitter that communicates between nerves and muscles. Epinephrine is a catecholamine that serves as a neurotransmitter that is released in the sympathetic branch of the autonomic nervous system and can be hormones when released from cells in the adrenal medulla. Gamma-aminobutyric acid is a neurotransmitter that inhibits nerve activity and prevents over excitability or stimulation.
A client is experiencing severe EPS effects. In addition to administering a lower dose of the antipsychotic agents, the nurse would anticipate administering a medication in which category? a. Cholinergics b. Anticholinergics c. Antidepressants d. Dopamine agonists
B ~ Anticholinergics, such as benztropine (Cogentin), are used to decrease the EPS effects associated with antipsychotic medications.
Client teaching is important when antipsychotics are taken after discharge from the hospital. Nursing instruction should include giving which information to the client and family? a. Therapeutic effect should occur in 2 to 3 days with maximum effect in 1 week. b. The drugs should not be discontinued without consulting a healthcare provider. c. Taking barbiturates in small dosages with the drug is usually permissible. d. Rapid change in position has little effect on dizziness or blood pressure.
B ~ Antipsychotic medications affect symptoms while they are used. If they are stopped, the symptoms will recur.
A client is brought to the emergency department unconscious. The clients spouse tells the nurse that the client was found in bed with an empty pill bottle nearby. The clients spouse believes that there were 20 to 25 diazepam (Valium) pills in the bottle. What represents an appropriate nursing priority? a. Administer an emetic agent followed by activated charcoal. b. Lavage the stomach using a nasogastric tube. c. Prepare the client for emergency surgery. d. Monitor the client because there is no antidote.
B ~ Because the client is unconscious, this is the correct course of action.
The nurse is caring for a patient who has a sedative hypnotic ordered. The nurse would consider this drug contraindicated if the patient had what disorder? A) Neurological diseases B) Liver failure C) Endocrine disorders D) Heart disease
B ~ Benzodiazepines undergo extensive hepatic metabolism. In the presence of liver disease, the metabolism of most benzodiazepines is slowed, with resultant accumulation and increased risk of adverse effects. Neurological disorders, endocrine disorders, and heart disease are not contraindications for the use of benzodiazepines.
What anxiolytic drugs would be given to a premenopausal patient who is a registered nurse planning to return to work at the hospital after anxiety is controlled? A) Alprazolam (Xanax) B) Buspirone (BuSpar) C) Diazepam (Valium) D) Clorazepate (Tranxene)
B ~ Buspirone is a newer anxiolytic drug that does not cause sedation or muscle relaxation. It is preferred when the patient needs to be alert such as when driving or working. Alprazolam, diazepam, and clorazepate are benzodiazepines, which cause drowsiness, sedation, depression, lethargy, confusion, and decreased mental alertness. It would be unsafe for a nurse to function in her role while taking one of these drugs.
When compared with benzodiazepines, buspirone (BuSpar) stands out as unique among antianxiety drugs because of what factor? A) Increases the central nervous system (CNS) depression of alcohol and other drugs. B) Lacks muscle relaxant and anticonvulsant effects. C) Causes significant physical and psychological dependence. D) Rapidly absorbed from the gastrointestinal (GI) tract and metabolized in the liver.
B ~ Buspirone, a newer antianxiety agent, has no sedative, anticonvulsant, or muscle-relaxant properties, and its mechanism of action is unknown. However, it reduces the signs and symptoms of anxiety without many of the central nervous system effects and severe adverse effects associated with other anxiolytic drugs. Most of the antianxiety drugs are rapidly absorbed from the GI tract, metabolized in the liver, have a significant drugdrug interaction with alcohol and other drugs, and can result in psychological dependence.
The patient has been severely depressed since her father died 6 months ago. The physician has prescribed amitriptyline. The nurse reviews the patients chart before administering the medication. What preexisting condition would require cautious use of this drug? A) Osteosarcoma B) Cardiovascular disorders C) Closed head injury D) Bleeding ulcer
B ~ Caution should be used with tricyclic antidepressants in patients with preexisting cardiovascular (CV) disorders because of the cardiac stimulatory effects of the drug and with any condition that would be exacerbated by the anticholinergic effects (e.g., angle-closure glaucoma, urinary retention, prostate hypertrophy, GI or genitourinary surgery). There is no indication that caution is needed with patients diagnosed with osteosarcoma, closed head injury, or bleeding ulcer.
The client has been placed on Risperdal. He complains to the nurse of experiencing headaches. The highest priority action on the part of the nurse is to recognize that this is a(n) ________ the medication and call the physician. a. adverse reaction to b. expected side effect of c. life-threatening reaction to d. anaphylactic reaction to
B ~ Headaches are an expected side effect of treatment with Risperdal.
An elderly patient has been taking zolpidem (Ambien) as a sleep aid for the past 2 months. On admission to the assisted-living facility, it is determined that the drug is no longer needed. What is an important nursing consideration concerning this drug? A) Hallucinations are common. B) The drug needs to be withdrawn gradually. C) Another anxiolytic will need to be substituted. D) Sundowning is common with withdrawal from this drug.
B ~ It is important for the nurse to understand that zolpidem must be withdrawn gradually over a 2-week period after prolonged use. If chloral hydrate is stopped suddenly, it will result in serious adverse effects. Hallucinations and sundowning are not common with withdrawal of the drug. The prescriber and the patient would determine the need for chloral hydrate to be substituted for another anxiolytic.
The client is known to have overdosed on a benzodiazepine medication. The nurse anticipates that which medication will most likely be ordered? a. Tranxene b. Romazicon c. BuSpar d. Librium
B ~ Romazicon is considered to be the benzodiazepine antagonist.
The nurse is caring for a resident in a long-term care facility who is African American with a history of an anxiety disorder. The patient is receiving oral lorazepam (Ativan) 2 mg t.i.d. When developing this patients plan of care, what priority assessment will the nurse include? A) Depression B) Extreme sedation C) Phlebitis D) Nightmares
B ~ Special care should be taken when anxiolytic or hypnotic drugs are given to African Americans. About 15% to 20% of African Americans are genetically predisposed to delayed metabolism of benzodiazepines. As a result, they may develop high serum levels of these drugs, with increased sedation and an increased incidence of adverse effects. Depression is not a common adverse effect. Phlebitis can occur at injection sites but this patient is taking the medication orally. Nightmares occur during drug withdrawal.
Why would the nurse expect the patient with liver disease to receive a smaller dose of benzodiazepines? A) Excretion of the drug relies on liver function. B) The drugs are metabolized extensively in the liver. C) They are lipid soluble and well distributed throughout the body. D) The drugs are well absorbed from the gastrointestinal tract.
B ~ The benzodiazepines are metabolized extensively in the liver. Patients with liver disease must receive a smaller dose and be monitored closely. Excretion is primarily through the urine. All of the answer options are true, but only the fact that the benzodiazepines are metabolized in the liver explains why a patient with liver disease would require smaller dosages.
The nurse is caring for a patient in intensive care unit receiving IV lorazepam (Ativan) to reduce anxiety related to mechanical ventilation. While injecting the medication the nurse notes a decrease in blood pressure and bradycardia. What is the nurses priority action? A) Discontinue drug administration. B) Give the IV drug more slowly. C) Notify the patients health care provider. D) Document the reaction to the drug.
B ~ The nurses priority action is to slow the rate of injection because rapid injection of benzodiazepines can result in hypotension and bradycardia and can lead to cardiac arrest.
A nurse is discussing the use of alprazolam (Xanax) with a 68-year-old patient. What statement indicates that the patient has an understanding of the drug? A) When I stop having panic attacks, I can stop taking the drug. B) This drug will calm me down in about 30 minutes after I take it. C) One dose will keep me calm for about 24 hours. D) I am taking an increased dose because of my age.
B ~ The onset of alprazolam is about 30 minutes. The drug must be tapered after long-term use and the duration is approximately 4 to 6 hours. Elderly patients usually have a reduced dosage.
The nurse evaluates teaching as effective when a patient taking a benzodiazepine states, A) I should always take the medication with meals. B) I should not stop taking this drug without talking to my health care provider first. C) I cannot take aspirin with this medication. D) I will have to take this medication for the rest of my life.
B ~ The patient makes a correct statement when saying the drug should not be stopped without talking to the health care provider first because withdrawal of benzodiazepines require careful monitoring and should be gradually withdrawn. Medications do not have to be taken with food, aspirin is not contraindicated, and the medication need only be taken while the condition being treated continues. Patients with anxiety may only need the medication for a few weeks whereas those with a seizure disorder may take it for longer periods of time.
A client is to receive a dose of fluphenazine hydrochloride (Prolixin) by intramuscular injection. What is the most important nursing intervention related to the injection? a. Massage the site vigorously after injection. b. Administer the drug using Z-tracking. c. Avoid rotating the injection sites. d. Select a 22- to 23-gauge needle.
B ~ This medication is very viscous and requires Z-track, deep IM injection to avoid muscle irritation.
The nurse is caring for a patient who is taking a benzodiazepine. The nurse knows that caution should be used when administering a benzodiazepine to the elderly because of what possible adverse effect? A) Acute renal failure B) Unpredictable reactions C) Paranoia D) Hallucinations
B ~ Use benzodiazepines with caution in elderly or debilitated patients because of the possibility of unpredictable reactions and in patients with renal or hepatic dysfunction, which may alter the metabolism and excretion of these drugs, resulting in direct toxicity. Dosage adjustments usually are needed for such patients. Acute renal failure, paranoia, and hallucinations are not commonly related to therapy with these medications in the elderly.
What drug, if prescribed for the patient, would indicate the need to assess the patient for depression characterized by anxiety and addictive behaviors? A) Imipramine (Tofranil) B) Venlafaxine (Effexor) C) Fluvoxamine (Luvox) D) Tranylcypromine (Parnate)
B ~ Venlafaxine is used to treat and prevent depression in generalized anxiety disorder, social anxiety disorder; it also diminishes addictive behavior. Fluvoxamine is a selective serotonin reuptake inhibitor, tranylcypromine is a monoamine oxidase inhibitor, and imipramine is a tricyclic antidepressant that are not indicated for treatment of anxiety disorder and addictive behavior.
A patient with severe depression has been hospitalized and the physician has ordered amitriptyline. What common adverse effect will the nurse monitor and assess the patient for? (SATA) A) Fever B) Myocardial Infarction C) Stroke D) Dry mouth E) Gynecomastia
B, C, D ~ Use of tricyclic antidepressants may lead to GI anticholinergic effects, such as dry mouth, constipation, nausea, vomiting, anorexia, increased salivation, cramps, and diarrhea. Cardiovascular effects (e.g., orthostatic hypotension, hypertension, arrhythmias, myocardial infarction, angina, palpitations, stroke) may occur. Fever and gynecomastia are not normally attributed to amitriptyline therapy.
What priority teaching point does the nurse include in the teaching plan for a patient on a monoamine oxidase inhibitor (MAOI)? (SATA) A) Take medication at bedtime. B) Monitor blood pressure. C) Do not take over-the-counter (OTC) drugs without talking to physician. D) Report double vision right away E) Reduce tyramine intake
B, C, E ~ MAOIs can cause drug-drug and drug-food interactions, which can precipitate cardiovascular effects that include orthostatic hypotension, arrhythmias, palpitations, angina, and the potentially fatal hypertensive crisis. Priority teaching points include monitoring blood pressure which will elevate with tyramine ingestion and the importance of not taking any OTC without physician or pharmacist consultation due to multiple drug-drug interactions. When taking an MAOI, you would not necessarily take the drug at bedtime or drink lots of fluid. Blurred, but not double, vision is an adverse effect of an MAOI.
Which medication(s) treat Myasthenia Gravis? a.Hydroxycholorquine b. Pryidostigmine c. Bethanechol d. Methotrexate e. Baclofen f. Edrophonium
B, F Response Feedback: A Myasthenia Gravis patient is lacing acetylcholine resulting in weak muscles. The goal is to increase acetylcholine levels utilizing choinestrase inhibitors. These will block the acetylcholine enzyme, cholinesterase, allowing more acetylcholine into the system. The cholinesterase inhibitors are: pyrdostigmine and edrophonium
Ginkgo
Brain Decreases dizziness and improve memory
What would the nurse assess for when benzodiazepines are abruptly stopped? A) Urinary retention and change in sexual functioning B) Dry mouth, constipation, nausea, and vomiting C) Nausea, headache, vertigo, malaise, and nightmares D) In most cases nothing significant
C ~ Abrupt cessation of these drugs may lead to a withdrawal syndrome characterized by nausea, headache, vertigo, malaise, and nightmares. When benzodiazepines are stopped abruptly the likelihood of withdrawal symptoms increases with the length of time the patient took the medication. Urinary retention, change in sexual functioning, dry mouth, constipation, nausea, and vomiting are all common adverse effects of the medications classified as benzodiazepines.
A patient presents at the free clinic complaining of nervousness, worrying about everything, and feeling very tense. What diagnose would the nurse suspect? A) Neurosis B) Psychosis C) Anxiety D) Depression
C ~ Anxiety is a common disorder that may be referred to as nervousness, tension, worry, or using other terms that denote an unpleasant feeling. The other options would not be described by these symptoms.
A patient arrives at the emergency room after attempting suicide by taking an entire bottle of diazepam. What antidote will the nurse most likely administer? A) Phenobarbital (Luminal) B) Dexmedetomidine (Precedex) C) Flumazenil (Romazicon) D) Ramelteon (Rozerem)
C ~ Flumazenil is an antidote to benzodiazepine overdose and is administered to reverse the effects of benzodiazepines when used for anesthesia. Phenobarbital, a barbiturate, would further depress the body functions of this patient. Dexmedetomidine is a new hypnotic drug used in the intensive care unit for mechanically ventilated patients. Ramelteon is also new; it is used as a hypnotic. Adverse effects of this drug include depression and suicidal ideation.
A nurse is working with a 9-year-old child who exhibits signs and symptoms of obsessive-compulsive disorder (OCD). What drug will the nurse anticipate may be prescribed for the child? A) Phenelzine (Nardil) B) Amitriptyline (Elavil) C) Fluvoxamine (Prozac) D) Isocarboxazid (Marplan)
C ~ Fluvoxamine is a selective serotonin reuptake inhibitor that has established pediatric dosage guidelines for the treatment of obsessive-compulsive disorder. Isocarboxazid and phenelzine are monoamine oxidase inhibitors and should be avoided in pediatric use because of the potential drugfood interactions and other serious adverse effects. Amitriptyline is also a tricyclic antidepressant not recommended for pediatric use.
Hypnotic drugs are used to aid people in falling asleep. What physiological system does a hypnotic act on to be effective in helping a patient to sleep? A) Limbic system B) Sympathetic nervous system C) Reticular activating system D) Lymph system
C ~ Hypnotics are used to help people fall asleep by causing sedation. Drugs that are effective hypnotics act on the reticular activating system and block the brains response to incoming stimuli. Hypnosis, therefore, is the extreme state of sedation, in which the person no longer senses or reacts to incoming stimuli. The other options are incorrect.
The client has been diagnosed with schizophrenia and is exhibiting a loss of function and motivation. The nurse recognizes that these symptoms are categorized as: a. positive. b. paranoiac. c. negative. d. incoherent.
C ~ Negative symptoms are manifested as the inability to initiate voluntary motor function. The others are considered positive symptoms.
The nurse is caring for a 36-year-old man who experienced a seizure 30 minutes before coming into the emergency room, where he begins to have another. What barbiturate has the fastest onset and would be most appropriate to give to the patient to quickly stop the seizure? A) Amobarbital (Amytal Sodium) B) Mephobarbital (Mebaral) C) Phenobarbital (Luminal) D) Secobarbital (Seconal)
C ~ Phenobarbitals onset is between 10 and 60 minutes, depending on the route administered, and most likely this would be given to the patient. Amobarbital is given for convulsions and the onset is between 15 and 60 minutes. Mephobarbitals onset is between 30 and 60 minutes. Secobarbital is given for convulsive seizures of tetanus and has an onset of 1 to 4 hours.
A nurse is caring for a 4-year-old child who is receiving a barbiturate. What common adverse effect would the nurse assess for? A) Decrease in respirations B) Vomiting C) Excitability D) Dry mucous membranes
C ~ The barbiturates, being older drugs, have established pediatric dosages. These drugs must be used with caution because of the often unexpected responses. Children must be monitored very closely for central nervous system (CNS) depression and excitability. The most common adverse effects are related to general CNS depression. Other CNS effects may include drowsiness, somnolence, lethargy, ataxia, vertigo, a feeling of a hangover, thinking abnormalities, paradoxical excitement, anxiety, and hallucinations. Alteration in respirations and dried mucous membranes are adverse effects of antihistamines, which can be given to calm children or induce sleep. Vomiting could occur with the use of paraldehyde due to the unpleasant taste and odor of the drug.
A client has been taking a phenothiazine for 1 week. She contacts the crisis intervention clinic because she is still having symptoms. The nurses response is based on the premise that the desired effects usually take _____ to manifest. a. 1 week b. 1 to 3 weeks c. 3 to 6 weeks d. 3 to 5 months
C ~ The client may feel some effect in 7 to 10 days, but generally it takes 6 weeks for the medication to take full effect.
The client is an older adult who has been placed on Librium. The nurse recognizes that the dose of the drug _____ for this client. a. is contraindicated b. should be increased c. should be decreased d. will not change
C ~ The dose of Librium should be decreased for an older adult.
The nurse is caring for a patient who experiences anxiety and insomnia and is prescribed benzodiazepines. When developing the plan of care, what would be an appropriate nursing diagnosis related to potential adverse effects of the drug? A) Provide patient teaching about drug therapy. B) Anxiety related to drug therapy. C) Risk for injury related to central nervous system (CNS) effects. D) Avoid preventable adverse effects, including abuse and dependence.
C ~ The most appropriate nursing diagnosis related to adverse effects of the drug is risk for injury related to CNS effects because benzodiazepines can have many CNS adverse effects. Anxiety is the condition for which drug therapy is prescribed not related to drug therapy. Patient teaching and avoiding adverse effects are interventions and not nursing diagnoses.
A client is to be treated with Prolixin. The highest priority nursing intervention related to the clients vital signs is to monitor for: a. bradycardia. b. hypertension. c. hypotension. d. tachypnea.
C ~ The phenothiazine groups major side effect is hypotension.
A nurse is about to administer a parenteral benzodiazepine to a female patient in the hospital before the performance of a procedure. What is the priority nursing action before administration of the drug? A) Make sure that the side rails are up and the bed is in the lowest position. B) Close the blinds and ensure appropriate room temperature for the patient. C) Help the patient out of bed to the bathroom and encourage her to void. D) Ask all visitors to leave the room and remain in the waiting area.
C ~ The priority action would be to help the patient up to void. After the medication is administered the patient should not get out of bed because of possibly injury due to drowsiness. Safety should always be the priority concern. After administration of the drug the nurse would ask visitors to leave before beginning the procedure, make the room conducive to rest and sleep, and make sure that both side rails are up and the bed is in the lowest position.
A client is ordered to receive fluphenazine (Prolixin) to manage the psychotic symptoms of schizophrenia. The nurse assesses for which signs of anticholinergic effects? a. Bradycardia and orthostatic hypotension b. Diarrhea and tachycardia c. Urinary retention and dry mouth d. Constipation and hypertension
C ~ Urinary retention & dry mouth are the side effects of anticholinergics.
A patient is experiencing an acute asthma attack. The nurse would expect the immediate treatment to include: a. cromolyn via metered-dose inhaler (MDI). b. fluticasone via metered-dose inhaler (MDI). c. albuterol via nebulizer. d. oral montelukast.
C. ALBUTEROL Response Feedback: Beta-agonists are commonly used for the treatment of acute asthmatic attacks. Fluticasone and cromolyn are used to reduce inflammation associated with asthma; montelukast is used for prophylaxis.
What is the BRAND NAME for CITALOPRAM?

What are some conditions that may mimic the behaviors of schizophrenia?
Chronic amphetamine or cocaine use Brain neoplasm Infections Hemorrhage
A client is receiving an antipsychotic agent. Which laboratory result is of most concern? a. Serum sodium level of 138 mEq/L b. Blood glucose level of 100 mg/dl c. White blood cell count of 6000/mm3 d. Serum medication level below normal limits
D ~ A serum medication level below normal limits is a concern because subtherapeutic levels may allow for breakthrough psychotic symptoms.
A patient comes to the mental health clinic for a regular appointment. The patient tells the nurse he has been taking oral fluoxetine (Prozac) 20 mg daily for the past 3 weeks and that he has lost 3 pounds during that time due to a loss of appetite. What action should the nurse take? A) Teaching the patient about healthy eating to maintain weight B) Congratulating the patient on his weight loss and commenting how well he looks C) Encouraging the patient to increase fluid intake to avoid further weight loss D) Reassuring the patient that a decrease in weight is a common adverse effect with this medication
D ~ Adverse effects of fluoxetine include anorexia and weight loss. Although teaching about healthy eating is a good idea, it is more important to teach the patient how to take the medication in a way that will reduce adverse effects as well as how to optimize healthy calories to maintain weight. The patient should increase caloric intake, not just fluid intake. The patient should continue the medication to see whether therapeutic effects are obtained and adjust nutritional intake if necessary. More information about the patients baseline weight is needed before congratulating the patient because a patient who is already too thin would not appreciate the nurses comment.
A patient receives a new prescription for fluvoxamine (Luvox). What will the nurse instruct the patient about taking the medication? A) Take medication after eating breakfast. B) Take medication with at least 8 ounces of liquid. C) The dosage may need to be increased if the patient is not feeling better in 2 weeks. D) The medication should be taken once a day before bedtime.
D ~ Fluvoxamine is a selective serotonin reuptake inhibitor that should be taken once a day before bedtime. The medication does not require 8 ounces of fluid for absorption. It should be taken for at least 4 weeks before a therapeutic effect is noted.
For what purpose would the nurse choose to administer a hypnotic instead of another classification of antianxiety drug? A) Treating insomnia B) Treating seizure disorder C) Treating panic attach D) Treating confusion and agitation
D ~ Hypnotics are used to help people fall asleep by causing sedation. Drugs that are effective hypnotics act on the reticular activating system (RAS) and block the brains response to incoming stimuli. Hypnotics would not be the most effective drugs to treat seizure disorders, panic attack, or confusion with agitation.
The nurse is preparing a dose of Mellaril. What is the highest priority intervention for the nurse while preparing the dose? a. Draw up the dosage of the liquid in an oral syringe. b. Use a 21-gauge needle to administer the injection. c. Start a new IV site before administering the drug. d. Avoid spilling the liquid on exposed skin.
D ~ If Mellaril is allowed to come in contact with exposed skin, contact dermatitis can result.
An older adult African American patient comes to the clinic and is diagnosed with generalized anxiety disorder (GAD). The physician orders oral flurazepam 30 mg. What is the nurses priority action? A) Teach the patient about the prescribed medication. B) Administer the first dose of medication. C) Tell patient to take first dosage after driving home. D) Talk to the physician about the dosage.
D ~ If an anxiolytic or hypnotic agent is the drug of choice for an African American patient, the smallest possible dose should be used, and the patient should be monitored very closely during the first week of treatment. Dosage adjustments are necessary to achieve the most effective dose with the fewest adverse effects. In addition, older adults also require careful titration of dosage. Older patients may be more susceptible to the adverse effects of these drugs, from unanticipated central nervous system (CNS) adverse effects including increased sedation, dizziness, and even hallucinations. Dosages of all of these drugs should be reduced and the patient should be monitored very closely for toxic effects and to provide safety measures if CNS effects do occur. As a result, the priority action is to talk to the physician about the dosage. The other actions may be appropriate after a proper dosage is ordered.
A client is ordered to receive diazepam (Valium). The nurse is teaching the client about her medication. Which information would be included in the teaching plan? a. The medication causes high levels of energy and activity. b. The medication is effective in aiding clients with suicidal ideations. c. The medication may be taken concurrently with other benzodiazepines. d. The client may develop tolerance after prolonged use.
D ~ Patients may become tolerant to Valium.
A 12-year-old patient is hospitalized with severe depression. The patient has been taking a selective serotonin reuptake inhibitor (SSRI). What is the priority nursing action for the patient? A) Monitor food intake for levels of tyramine. B) Assess for weight loss and difficulty sleeping. C) Monitor the patient for severe headaches. D) Implement suicide precautions.
D ~ Recent studies have linked the incidence of suicide attempts to the use of SSRIs in pediatric patients (see box 21.3 Focus on the Evidence). The priority concern for the nurse would be safety for the patient. Severe headache and reactions to tyramine-containing foods are associated with monoamine oxidase therapy. Weight loss and difficulty sleeping are of a lower priority concern than the patients safety.
What is the physiological action of tricyclic antidepressants (TCAs)? A) Inhibiting monoamine oxidase inhibitors that break down norepinephrine B) Inhibiting nerve activity, which prevents over excitability or stimulation C) Blocking the reuptake of serotonin, which increases the levels of norepinephrine D) Inhibiting reuptake of norepinephrine and serotonin
D ~ TCAs inhibit presynaptic reuptake of norepinephrine and serotonin, which cause an accumulation of the neurotransmitters that is thought to create the antidepressant effect. Monoamine oxidase inhibitors irreversibly inhibit monoamine oxidase that breaks down norepinephrine and serotonin. Selective serotonin reuptake inhibitors block the reuptake of serotonin; gamma-aminobutyric acid inhibits nerve activity.
A nurse is caring for a 9-year-old patient and has received an order for diazepam (Valium) 10 mg given orally q.i.d. What is the nurses priority action? A) Perform hand hygiene and prepare the drug. B) Send the order to the hospital pharmacy. C) Determine when to administer the first dose. D) Call the physician and question the order.
D ~ The first action of the nurse would be to call the physician and question the order. The normal oral dosage for a pediatric patient is 1 to 2.5 mg t.i.d. or q.i.d. The ordered dose would be unsafe for this patient. If the dosage was changed and the correct amount administered, the nurse would order the medication from the pharmacy if necessary and determine what time to start the medication. She would then wash her hands in preparation for administering the medication, but not until obtaining an appropriate dosage of medication.
A patient is being discharged home from the hospital after receiving treatment for pneumonia. The patient is going home and continuing to take the same drugs he or she was taking before he or she was hospitalized. These drugs include an antianxiety medication and a medication for insomnia. The home care nurse is following this patient. On the initial visit what is the nurses priority teaching point? A) The names and purposes of medications prescribed B) How to contact the provider if needed C) The importance of taking medications for insomnia only occasionally D) Warning signs that may indicate serious adverse effects
D ~ The home care nurse should provide thorough patient teaching, with a priority teaching point being the warning signs the patient may experience that indicate a serious adverse effect. Although this may have been discussed by the discharging nurse in the hospital, this is essential information for the patient to thoroughly understand. By the time the home care nurse visits, the patient should already have filled the prescriptions and know the names and purposes of the medications prescribed from the hospital nurse but it is a good idea to review this information, although it is not a priority. Medications for insomnia should be taken as prescribed. The patient should have received the providers contact information when leaving the hospital but the home care nurse may need to review this, even though it is not the priority teaching point.
The nurse is caring for a patient who has not been able to sleep. The physician orders a barbiturate medication for this patient. What adverse effect should the nurse teach the patient about? A) Double vision B) Paranoia C) Tinnitus D) Thinking abnormalities
