Pharmacology 2 Exam2

QuestionAnswer
Describe the basic pathophysiology of Parkinson’s disease The dopamine neurons in the extrapyramidal motor pathway are destroyed leading to too much acetylcholine and GABA stimulation-> slowed body movements, tremors, masked faces, pill rolling
T/F- Parknison’s is a syndrome not a disease because it it characterized by a cluster of symptoms. True
What are some pharmacological treatments of Parkinson’s? Anticholinergics- movement disorders, Dopamine agonists- increase dopamine to replace motor movements, MAOI-B and COMT inhibitors stop breakdown of dopamine when used earlier in disease
What is the drug Carbidopa-Levodopa (SInemet) used to treat? How does it work? Used in Parkinsons, replaces dopamine, L converted to dopamine and C prevents L from converting until after it crosses BBB because dopamine doesn’t cross BBB. Must take high doses to work
What are some common and adverse reactions to Sinemet (Carbidopa-Levodopa)? Used to treat Parkinson’s, may lead to anticholinergic effects, NV, hypotension, dizziness, dark urine. May also cause Rebound Parkinsonism, agranulocytosis, cardiac arrhythmias, and Neuroleptic Malignant Syndrome
You are the nurse teaching a patient about Carbidopa-Levodopa (Sinemet). What should you teach? Alcohol is ok in moderation, Take multivitamins daily, Take high protein diet, Take with meals. Take with meals because NV is the most severe side effect because it stimulates the nausea center in brain, (Note- no alcohol, protein increases BUN which is bad)
T/F- Having too much OR too little Dopamine can worsen Parkinsonian symptoms True
T/F- There are varied treatments for individuals presenting with psychosis so it is important to know the exact etiology (ie Schizophrenia, Depression, Intoxication, Traumatic Brain Injury, Dementia). False, we treat people with psychotic symptoms similarly.
What is the Black Box Warning for antipsychotics? Elderly Patients with Dementia-Related Psychosis who are treated with an antipsychotic have increased mortality rates.
What medications are used to treat schizophrenia spectrum disorders and psychoses?
What are the expected effects of antipsychotics? When will the patient experience maximum relief? Remove or significantly reduce the psychotic symptoms. Max relief after several weeks or months on medication, start to notice changes in first few doses.
How do traditional antipsychotics improve psychotic symptoms?- Inhibit enzymes at receptor sites, Block Post-synaptic dopamine receptor sites, Increase dopamine uptake at post-synaptic receptor sites, Decrease serotonin at post-synaptic receptor sites. Block Post-Synaptic dopamine receptor sites which stops the positive symptoms
You have two patients on antipsychotics. One taking traditional antipsychotic, other is taking an atypical. You know that this patient is more likely to lead to peripheral side effects because it is nonselective and blocks ALL dopamine receptors. Traditional
You have a patient with positive and negative symptoms of psychosis. You expect the order to be for a __________ antipsychotic. Atypical, these were developed later and block some dopamine and also some serotonin which can lead to reduction of positive and negative symptoms
What are the 2 major categories of traditional antipsychotics? What differentiates them? Phenothiazines- such as Thorazine and Fluphenazine block NE (leading to sedative and hypotension) Nonphenothiazines such as Haloperidol-Block Dopamine
Which type of traditional antipsychotic is more effective in treating psychotic symptoms, Low potency Phenothiazine, High Potency Phenothiazine or High Potency Non-Phenothiazine? All have same efficacy, low potency meds require higher doses to be as effective. Have varied side effect profiles.
What is the mechanism of action of traditional antipsychotics? Blocks the D2 receptor sites in mesolimbic pathway to stop positive symptoms, non-selective dopamine blockade can lead to other side effects such as EPSE, histamine antagonism, acetylcholine blockage, Parkinsonism, sedation, and orthostatic hypotension
Why do traditional antipsychotics like Haldol make patients sleepy? Nonselectively binds to dopamine receptor sites which leads to histamine antagonism which leads to sedation
Extrapyramidal side effects associated with antipsychotic medications include acute dystonia. What is this? When does it develop? How to treat? Severe muscle spasm develops within first days of medication, usually involves tongue, neck, face, back, and laryngeal muscles. Can be fatal when head/neck muscles involved. Need medical attention to reverse. Caused when too much dopamine is blocked.
What is antipsychotic induced Parkinsonism? When does it develop? Treatment? Symptoms? An extrapyramidal side effect associated with too much dopamine blockage, develops within first month of taking antipsychotic, usually resolves on its own within a few months. Signs include akinesia, muscle rigidity, tremor, drooling, mask-like faces
Akathisia is an extrapyramidal side effect associated with antipsychotic medications. What is this? What cause it? Signs? When does it develop? Treatment? Too much dopamine blockage can cause a profound sense of restlessness and anxiety. Develops within first 2 months. Major reason people stop taking antipsychotics.
Patients taking an antipsychotic should be warned about the potential for developing tardive dyskinesia. What is this? Treatment? How common is it? When does it start? Involuntary twisting movements, begins with tongue and face and may progress to limbs and trunk. Can be IRREVERSIBLE (and often is). 15-30% of longer term users will develop it. It can happen at any time during the medication administration
Benztropine and Trihexyphenidyl are used to treat Parkinson’s disease and can also be used to treat parkinsonism side effects in patients taking antipsychotic medications. How do these work? block the central cholinergic receptors (act as anticholinergic). When dopamine is suppressed (as with patients taking antipsychotics) the cholinergic effects are more pronounced (drooling, muscle spasms and movement etc… think PNS with acetylcholine)
Why would a patient who is taking antipsychotics also be prescribed diphenhydramine? This histamine blocker is useful in treating extrapyramidal side effects by suppressing the central cholinergic activity and prolonging the action of dopamine by preventing its reuptake and storage
What are some of the signs of antipsychotic overdose? Hypotension, CNS depression, extrapyramidal side effects, atropine psychosis, death (although it is rare)
What is atropine psychosis? Symptoms? Psychotic delirium caused by excessive anticholinergic effects or by blocking too much acetylcholine, symptoms include agitation, confusion, dry flushed skin, tachycardia
Another adverse effect of antipsychotic medication is neuroleptic malignant syndrome. What is this caused by? Symptoms? Fatality? Blocking too much dopamine >parasympathetic and sympathetic dysregulation. occurs within same day you take a dopamine blocker Symptoms include sudden high fever, sweating/drooling, rigidity/tremors, changes in LOC including seizures and death (10-20%)
T/F- Patients taking an atypical antipsychotic do not have to worry about neuroleptic malignant syndrome like patients taking a typical antipsychotic. False, its caused by too much dopamine blockage so possible in both
Among the man adverse effects of antipsychotics, agranulocytosis is included. What is this? Symptoms? Fatality? Characterized by severely decreased WBC count which puts patient at profound risk of infection and death from overwhelming infection. Suspect if develops sore throat, fever, or malaise during the first 2 months of medication initiation
What are some adverse effects of antipsychotics? Hypotension, Sedation, Seizures, Arrythmias associated with sudden death, agranulocytosis, NMS, tardive dyskinesia, atropine psychosis,
A patient taking an antipsychotic medication may experience a variety of anticholinergic side effects including __________. Why? Dry mouth, congestion, blurred vision, constipation, urinary retention. Antipsychotics block M-1-cholinergic receptors (although the aim is for them to only block the dopamine)
Do high or low potency antipsychotic medications do the following- (More anticholinergic effects, sedation and hypotension) and (less anticholinergic effects and more extrapyramidal side effects) Low is More anticholinergic, High is less anticholinergic and more EPSEs.
T/F- Antipsychotic medication may cause dermatological side effects such as pruritic maculopapular rashes and short lived jaundice that usually goes away. True!
A 25 year old female taking an antipsychotic tells you she hasn’t had a period in 4 months. You tell her… Antipsychotics may cause amenorrhea but ovulation is still occurring (so you can still get pregnant). Medications that block dopamine cause amenorrhea because it regulates prolactin. It does NOT interfere with effectiveness of birth control.
List some common adverse effects in female clients taking antipsychotics. Gynecomastia, Galactorrhea (inappropriate milk production r/t prolactin deregulation) Menstrual irregularities, Decreased libido, Impaired ability to achieve orgasm
What are some common adverse effects of antipsychotic medication specific to male clients? Gynecomastia, decreased libido, erectile/ejaculatory dysfunction
T/F- Antipsychotic medications may lead to glucose dyscontrol and weight gain. True.
Why are atypical antipsychotic medications good? Treat positive and negative symptoms of schizophrenia, cause fewer extrapyramidal side effects r/t lesser dopamine affinity, lower risk of developing TD and less likely to elevate prolactin levels
Science assumes certain things about atypical antipsychotics and their effectiveness at treating negative symptoms. What are these? We think negative symptoms are caused by hypodopaminergic processes in FRONTAL lobe. Selective subtypes of serotonin inhibit dopamine. Drugs that antagonize the serotonin subtypes will increase frontal lobe dopamine.
What is Metabolic Syndrome as associated with atypical antipsychotic use? Insulin resistance, Hypertension, High serum lipids, Obesity, and Coagulation abnormalities. WARNING
Abilify or Aripiprazole is an atypical antipsychotic. It is special and different from most other antipsychotics in that it… Is a serotonin and dopamine agonist and antagonist but is PRIMARILY a dopamine antagonist (potential for EPSE’s and parkinsoninism) and Serotonin agonist (CNS stimulation)
A patient is taking Clozapine (an atypical antipsychotic). Which lab value do you care about MOST? (Renal function study, Hepatic function study, WBC, Serum Clozapine levels) WBC because agranulocytosis can lead to infection and death
Ziprasidone (Geodone) is known for what common adverse reaction? Clozapine is known to cause what significant adverse reactions? Geodone- Cardiac events. Clozapine- Agranulocytosis and Seizures
When managing a patient with schizophrenia, how do you select a drug and doasage? How long until you see improvements? What do you monitor for? Select based on PMH and treatments and family history. Start with divided doses, see symptom decline in 1-2 days and gradual improvement over months, Monitor for EPSEs
For a patient who is hospitalized and otherwise not diagnosed with any psychiatric illnesses but experiencing agitation and delirium, you expect to administer… Haloperidol
T/F- Atypical antipsychotic medication come in a variety of preparations including PO, quick dissolve, and IM but never IV. True
T/F- Traditional antipsychotic medications can be PO, IV, or IM including DEPOT. True
Some of the traditional antipsychotics come in DEPOT preparations. What are these? Benefits? Drawbacks? Long-acting injectable medications to treat schizophrenia, good for patients who are forgetful/noncompliant. Very expensive, IM injections every 2-4 weeks, may still require PRN medications. Cannot retrieve medication once administered.
There are many interactions with antipsychotic medications that a nurse should be aware of. List some. CNS depressants. Anticholinergics. Antihypertensives (increase hypotension). Levodopa (counteract effects converted to dopamine in body). Smoking (increase metabolism antipsychotics but decrease medication induced parkinsonism)
How do you safely administer antipsychotics for the best outcomes while minimizing the adverse effects? Give the lowest maintenance dose, treat the side effects, teach the patient, consider best formulation for patient, develop a therapeutic relationship
Whata re the expected and adverse effects of medications used to treat the neurocognitive disorder, Alzheimer’s Dementia?
What neurotransmitter alterations are associated with Alzheimers type dementia? Decreased acetylcholine leading to decreased acetyltransferase (interferes with cholinergic innervation in brain) Increased glutamate (results in overstimulation of NMDA, increased intracellular calcium, Neuron degeneration, and cellular death
What medication is currently being used to slow the progression of alzheimers type dementia? How does it work? Side effects? Interactions? Rivastigmine (Exelon) is an acetylcholinesterase inhibitor that prevents the breakdown of acetylcholine. SE-NVD, dizziness, headache, cholinergic, bronchoconstriction. Interacts with traditional antipsychotics, TCAs and antihistamines
What is the function of the N-Methyl-D Aspartic (NMDA) antagonist Mematine (Namenda)? used to improve symptoms of patients with alzheimers type dementia can be used alone or with the cholinesterase inhibitors. It inhibits glutamate and affects the NMDA receptors to regulate calcium. May cause dizziness, HA, confusion, and constipation
T/F- Estrogen increases the risk of developing Alzheimer’s type dementia. True!
According to the biogenic amine theory of depression, depression is caused by… A deficiency of monoamines (NE and Serotonin specifically)
According to the receptor sensitivity hypothesis of depression, depression is caused by… Supersensitivity and up-regulation of the receptor sites on neurons. Basically, the post-synaptic neuron is trying to compensate for a lack of NE and serotonin stimulation by becoming extra sensitive.
What do MAOI’s do? Why are they used to treat depression? they irreversibly block monoamine oxidase for 10-14 days, which inactivates monoamines (NE and Serotonin). So that there are increased amounts of NE and 5HT.
What is lag period? Why does it occur? Time between starting a medication and experiencing full symptom relief. Believed to occur because of down regulation which reduces the stimulation at the post-synaptic site.
What patient education is important to deliver and understand in regards to using antidepressants? Start at lowest dose and increase as needed, may have lag period, SE’s will usually occur within first 2 weeks. SUICIDE risk INCREASES with increasing ENERGY
When administering antidepressants to youth, you as the nurse know that there is a black box warning which says… Antidepressants increase the risk of suicide in children and adolescents. Need close monitoring and observation for suicidality and manic behavior. Family needs education
How do tricyclic antidepressants work? Inhibit the reuptake of norepinephrine and serotonin. Within the class, there is variation of SE profiles related to varying affinity for cholinergic, adrenergic, histamine and dopamine receptors.

You know that this class of antidepressants should NEVER be mixed with any other antidepressants or Anesthetics, Narcotics, Sympathomimetics, Cocaine, or antihyptertensives. MAOIs
A client is taking a TCA. You suspect toxicity because… Cardiac monitor reveals slowed conduction through heart and anticholinergic symptoms of agitation/confusion as well as seizures or coma.
T/F- Patients taking TCA’s need to have their plasma levels closely monitored. False, focus on whether it is working and side effects, only take if worried about OD or not taking. You do need to titrate when stopping medication and have baseline ECG
Part of the education for a client taking an MAOI includes avoiding tyramine rich foods like aged cheese and other antidepressants. Why? Tyramine is usually degraded by MAO, but if not degraded leads to increased BP and eventually hypertensive crisis. If you take an MAOI, you cant have a pepperoni pizza with a glass of wine or you will die of hypertensive crisis.
If a patient taking an MAOI calls in and reports suddenly high BP and headache or confusion, nausea, apprehension, stiff neck, fever, pallor, palpitations what do you tell them… Take Nifedipine SL while someone calls 911 to get you to hospital, decrease BP as quickly as possible

What is serotonin reuptake inhibitor withdrawal? When does it occur? What does it cause? More common when patient stops taking SSRI with shorter half life, occurs abruptly and lasts for 1-2 weeks, miserable, causes NVD, bloating, confusion, mania, flu like, agitation, depression. Treat by putting back on med
What is Central Serotonin syndrome? What causes it? When does it occur? May occur within minutes up to 72 hours after starting a med that increases serotonin. Can causes mental (Restless, \/LOC, Coma), autonomic (Diaphoresis/^HR, HTN, Hyperthermia, Shock), and neuromuscular changes (Spasm, Rigidity, Tonic-Clonic seizures).
A patient taking an SSRI should avoid what other medications… Antidepressants and NSAIDS and anticoagulants (increases risk of bleeding as Serotonin blockage may make platelets less effective)
The atypical antidepressant Effexor (Venlafaxine) does what… Side effects? Serotonin-norepinephrine reuptake inhibitor. Does NOT block cholinergic, histaminergic, or alpha1 adrenergic receptors. May cause Headache, anorexia, insomnia, Serotonin syndrome, NMS, HTN, bleeding, mania
T/F- Atypical antipsychotics usually have fewer negative SEs than typical antidepressants because they are less selective. False, they do have fewer SE’s but that’s because they are MORE selective
As a nurse, you know that many patients run into problems with their antidepressant treatment because… Inadequate dosage, DC prior to full recovery, didn’t taper when DC, polypharmacy related to treatment resistance
When managing a client with depression, aside from antidepressants, you could expect a patient to be prescribed… Benzodiazepines to decrease anxiety and agitation, Mood stabilizers to control labile mood, and Antipsychotics to decrease psychotic symptoms seen in severe depression
What are the expected functions of mood stabilizers? Relieve labile mood symptoms in patients without bipolar. Relieve symptoms during mania/depression of BPAD, prevent recurrence of mania/depression in bipolar
What is the gold standard mood stabilizer? How does it work? What is it? Lithium is an inorganic ion that alters the distribution of sodium and potassium to stabilize cell membrane, stabilizes electoral activity of neurons, and leads to decreased neuronal activity by decreasing glutamate
The nurse knows that a patient taking Lithium is at risk for becoming toxic if… They become dehydrated as lithium interacts with Na and K
Lithium levels are dependent upon _______function. Renal. Lithium is excreted unchanged via kidneys. Dehydration causes retention (Lithium and Na are interchangeable). When sodium is displaced, lithium takes its place and kidneys go to waste
What are the therapeutic plasma levels of lithium during the acute phase? During the stable phase? Toxic? Acute- 0.8-1.4 mEq/L. Stable- 0.4-1.0 mEq/L. TOXIC >/= 1.5
Teach the patient about the adverse effects of lithium. Headache, muscle weakness, fatigue, confusion, tremor, renal toxicity, fetal effects, POLYURIA/POLYDIPSIA, do NOT breastfeed while taking Lithium, weight gain, ECG changes, decreased WBC
What assessments do you as the nurse expect to be ordered before starting a patient on lithium? General health status, KIDNEY function, thyroid function, CBC, Electrolytes, Baseline ECG
You need to know the signs of lithium toxicity, both early and progressive as well as most common. Early (polydipsia/polyuria, Lethargy, tremor, NVD) Progressive (Oliguria/anuria, Confusion, seizures, blurred vision, tinnitus, coma Death
How do you treat moderate lithium toxicity (1.5-2)? Severe? Moderate- Hold, check levels, re-evaluate dosage. Severe- Stop med, increase excretion, renal dialysis
Lithium can be hard for patients to take properly due to frequent monitoring and dosing. What is common? 300 mg TID/QID up to 1200 mg, yearly CBC, lytes, renal/thyroid function,
Another mood stabilizing medication is actually an anticonvulsant called Valproic acid or Depakote. This is a good choice fore rapid cyclers. How does it work? Concerns? Useful in what type of patients? Suppresses sodium channels and calcium influx and augments GABA. REQUIRES frequent LFTs. Considered to be first line treatment for bipolar over lithium.
Benzodiazepines can be used to treat anxiety. How do they work? Expected outcome? Binds to specific receptor sites to enhance actions of GABA leading to reduced anxiety.
This medication is a commonly used benzodiazepine with shorter half life than others. can cause CNS/respiratory depression, amnesia, Paradoxical psychological effects, Tolerance/Dependence, Schedule IV drug that readily crosses the placenta and breatmilk. Alprazolam (Xanax).
What are the advantages of using a benzodiazepine to relieve anxiety? Rapid onset, well tolerated, few drug interactions *Alcohol*, few CVS effects *when given PO, Generics are available, only activate existing GABA receptors
Buspirone (Buspar) is an antianxiety agent. How does it work? What are the side effects? Binds with serotonin receptors/some dopamine. Take with food***. Peak at 3-6 weeks No euphoria like Benzos, doesn’t affect GABA, not controlled substance, takes 3-6 weeks to work, no risk for OD, used for GAD. Dizziness, nausea, headache, excitement

Explain the differences between premature, Inhibited, and Retrograde ejaculatory dysfunction. Premature- too soon. Inhibited- too late. Retrograde- ejaculation flows backward into the bladder
A patient complains of premature ejaculation and asks what causes it and what they can do. You say… Psychological factors (anxiety/stress/anticipation). Lidocaine cream to delay, Keegles, Pharm therapy, herbals?
A patient complains of inhibited ejaculation and asks what causes it and what can be done. You say…” Physiological factors (age/structure/ NS pathology) Psychologic factors, Medications. Treat the underlying problem. Consider dopamine agonists and anti-serotonergic agents.
A patient has been told that he has retrograde ejaculation and is concerned. You tell him. This is not harmful, it involves the backflow of semen into the bladder. It may cause infertility. Associated with BPH and blocked urethral passage
What does failure to detumescence or Ischemic Priapism mean? What causes it? Treatment? Ischemic- blood trapped in penis can’t get out veins.

What is Tamsulosin (Flomax)? What is it used for? What are the adverse effects and nursing implications? An alpha1 adrenergic blocker that relaxes smooth muscles in neck of bladder and prostate in patients with BPH. Can cause hypotension, orthostasis, dizziness. Don’t crush it (risk for profound hypotension)
What is gender dysphoria? When do most people experience this? Strong feelings of identification with opposite gender, distress of assigned sex, dysphoria becomes worse with puberty (Tanner stage 2)
What is the goal of transgender treatment? Ameliorate gender dysphoria, improve sexual function, achieve serum hormonal levels within the normal biologic range of born males or born females
When a transgender individual is taking hormone therapy drugs, what are the goals? Induce secondary sex characteristics, virilization, diminish secondary natal sex characteristic, no RCTs to support proper dosages or formulations. Basically, get them to conform with desired gendered appearance.
What is included in Female to Male Hormone therapy? What are the legal and ethical initiation concerns? Gonadotropin releasing hormone agonist (LH and FSH-> testosterone, Estrogen, Progesterone, Sperm…) Testosterone, Progestin. Hormone therapy may mean permanent changes, may start at 16 yo (tanner stage 2).

Why would an adolescent transgender take partial reversible therapy? give testosterone> premature closure of growth plates and alter stature, indicated in individuals with strong gender dysphoria that is worsened with puberty. Taper doses of Testosterone up every 6 months until reaching adult dose of 75-100 mg
What is the target dosing for testosterone in the transgender population? What are the target outcomes? Serum levels? 75-100 mg IM weekly and 200-250 mg q2weeks IM. Goal to suppress menses and virilize body/face and hair. Serum levels measured every 2-3 months goal range 320-1000 ng/dL with Estradiol <50pg/mL
How old must an adolescent be to undergo irreversible surgical reassignment? 18 yo
An adult hormone therapy for transgender FtM may require the addition of daily progestin. Why? used to halt menses or if estrodial levels are too high
T/F- Patients who want to transition from female to male can expect the same physical outcomes regardless of age initiated. False- advanced age may mean that the physical changes are less appropriate to desired gender (shorter, wider hips, fat deposit locations)
What is involved in virilization? Development of male characteristics. Facial/Body hair. Increased muscle mass. Deeper voice, Adam’s apple. Redistribution of fat. Cessation of menses. Increased libido. Male physical contours.

What are the surgical steps of female to male gender reassignment? Mastectomy, Hysterectomy/Ovariectomy, Vaginectomy, Urethral reconstruction, Scrotoplasty/Penile reconstruction, Penile/testicular implants, Metodioplasty (microphallus for urination while standing)
There are several progestin-only contraception methods. Name some. Depo-Provera, Mini-pills, IUDs and Nexplanon.
How is the progestin only mini-pill different from the combined mini-pill? Each progestin only pill is worth 24 hours of protection. These must be taken at the EXACT same time each day. If more than 3 hours late, need a backup. Each pill has progestin in it so you have to take all. Not as effective.
The depo-provera is another progestin only contraception method. How is it administered? Frequency? Monitoring? Concerns? How does it work? IM injection q12weeks, can cause weight and BP increase. Can lead to osteoporosis. Must be on calcium and vitamin D. Suppresses ovulation and changes the cervical mucus.
What is the mechanism of action for progesterone only contraception? Who are these recommended for? Changes the endometrial and cervical mucus. Makes the uterus inhospitable. Good for women who can’t take combined methods, undiagnosed vaginal bleeding, hepatitis/cirrhosis. Breastfeeding, HTN, and women over 35 who smoke.
What are long-acting reversible contraceptives? Progestin only methods of contraception such as Mirena and Skyla (IUDs) and Nexplanon. Also includes the non-hormonal method Paragard (IUD)
Whats the difference between mirena and Skyla? Same? Both Progestin only Long acting reversible contraception made by same company. Sits at top of uterus. Immediate return to fertility after removal. Check strings monthly. Sklya 3 years, smaller, 14mcg/day. Mirena 5 years, 20 mcg/day
