NR 601 final review.docx NR 601 Comprehensive Final exam study guide and practice questions DISCLAIMER- None of this is my original work. The first 11 pages are the completed study guide from a previous class. Pages 11 through 13 are the NR 601 course final exam review topics in outline form (Thanks Lisa Trevino!). Page 13-46 includes my notes from class and YouTube videos, Kennedy-Malone text (minimal), lessons, and some external research. When the information came from an external article, I included a link so that you do not use it as a test resource. Hopefully this is helpful for us as both a test and boards review. I kinda sorta (but not really because I’m over it) apologize for any typos. How to conduct Mini-Cog The Mini-Cog has been demonstrated to have comparable psychometric properties to the MMSE  The primary advantage of the Mini-Cog is that it is shorter than the MMSE and measures executive function.  It is composed of a three-item recall and the Clock Drawing Test (CDT) and takes about 3 minutes to administer  The Mini-Cog is a short dementia assessment that combines three-word recall with clock-drawing capability.  Patients are given a total score reflecting accuracy in clock drawing and recollection of the given three words.  A score of 0 to 2 is a positive screen for dementia Causes of delirium in elderly Causes of delirium are numerous and in elderly hospitalized patients there are often multiple etiologies, including metabolic, infection, cardiac, neurological, pulmonary, sensory impairments, medications, and toxins.  Regardless of cause, a consistent finding is significant reduction in regional cerebral perfusion during periods of delirium in comparison with blood flow patterns after recovery.  A possible neurological common pathway may involve acetylcholine and dopamine, and the disruption in the sleep-wake cycle in delirium indicates melatonin as a possible factor. (Kennedy-Malone 59) Agnosia  Loss of ability to identify objects ADA criteria for diagnosing DM FPG ≥126 mg/dL (7.0 mmol/L). Fasting is defined as no caloric intake for at least 8 h.*  2-h PG ≥200 mg/dL (11.1 mmol/L) during OGTT. The test should be performed as described by the WHO, using a glucose load containing the equivalent of 75-g anhydrous glucose dissolved in water.*  A1C ≥6.5% (48 mmol/mol).

Most patients adjust to these SE. ADVERSE effect- Lactic acidosis. B12 deficiency  Biguanides (Metformin) has become a cornerstone of drug treatment for type 2 disease, based on its proven efficacy not only in controlling glucose intolerance but also in significantly reducing risk of important macro- and microvascular outcomes, especially in overweight and obese patients (as found in the UKPDS study referred to 6earlier and below). In glycemic treatment algorithms for type 2 disease, initiation of metformin is recommended at the time of diagnosis along with diet and exercise.  Mechanism of Action. Metformin differs from the traditional oral hypoglycemics (i.e., the sulfonylureas) in that it does not stimulate endogenous insulin secretion; rather, drugs of this class enhance tissue responsiveness to insulin. Consequently, biguanides are less likely to induce hypoglycemia and are particularly effective in the treatment of overweight patients with tissue resistance to insulin. Biguanides facilitate insulin uptake by peripheral tissue, especially muscle and liver, and decrease hepatic gluconeogenesis and basal glucose output, thereby helping to lower fasting glucose levels. Glucose utilization also improves in adipose and intestinal tissues. The net result is an improvement in fasting and postprandial hyperglycemia. Insulin demand declines as glucose utilization improves. Serum lipid abnormalities also improve.  Preparations. Metformin is the only biguanide approved in the United States for the treatment of type 2 diabetes. The drug is rapidly and well-absorbed in the small intestine, with peak plasma concentrations in 2 hours. It is rapidly excreted unchanged by the kidneys. Impaired renal function (creatinine >1.5 mg/dL in men and >1.4 mg/dL in women) is a contraindication for use, especially at full doses. The drug is not metabolized by the liver. The original biguanide, phenformin, is no longer marketed because of its associated risk for lactic acidosis and an excess cardiovascular mortality (see later discussion).  Dosing. The starting dose of metformin is 500 mg once daily with dinner. After 1 week, the dose is increased to twice daily, given with the two largest meals of the day (usually breakfast and dinner) to minimize gastrointestinal upset. The dose can be increased by 500 mg every 1 to 2 weeks until treatment goals are met or the maximum dose of 2,000 to 2,500 mg/d is reached. An extended-release formulation is also available, which can help to improve compliance.  Efficacy. When used as monotherapy in an obese person with moderate glucose intolerance, metformin’s efficacy in terms of glycemic control (i.e., lowering fasting glucose and glycosylated hemoglobin levels) is about the same as that of a second-generation sulfonylurea. Incidence of monotherapy treatment failure is less for metformin than for glyburide (21% vs. 34% at 5 years). A synergistic effect is achieved when combined with sulfonylurea therapy in patients who do not respond well to metformin alone. Unlike the sulfonylureas, metformin is effective even in severe fasting hyperglycemia (>300 mg/dL), indicative of poor beta-cell responsiveness. Plasma triglycerides and LDL cholesterol levels are decreased. In the UKPDS trial noted earlier, obese patients (>120% of ideal weight) with type 2 diabetes treated with metformin and attaining target glycemic control achieved clinically important, statistically significant, sustained long-term reductions in risks of microvascular disease and macrovascular complications (i.e., myocardial infarction, stroke, and cardiovascular death); all-cause mortality was also significantly reduced. These findings make metformin one of the few antihyperglycemic drugs with demonstrated ability to reduce macrovascular risk, the holy grail of diabetes management.  Adverse Effects. The most common side effect of biguanide therapy is dose-related gastrointestinal upset (nausea, diarrhea, bloating, abdominal discomfort). The risk for serious prolonged hypoglycemia is minimal. Lactic acidosis represents the most potentially serious adverse effect. One of the original biguanides—phenformin —was taken off the market by the U.S. Food and Drug Administration (FDA) in 1977 because of its association with fatal episodes of lactic acidosis. The risk for lactic acidosis associated with metformin is greatest in the setting of hypoxemia, hypovolemia, and states with decreased tissue perfusion and in renal insufficiency (creatinine >1.5 mg/dL). Accumulation of the drug secondary to reduced excretion results in impaired hepatic metabolism of lactate. Other risk factors include binge drinking, use of intravenous radiologic contrast agents, hepatic failure (lactate is metabolized by the liver), and serious underlying illness, particularly heart failure.Long- term data on safety have yet to be accumulated. Because insulin secretion is not increased with metformin use, weight gain does not occur; some patients may even lose weight. Patients who are to undergo a radiologic procedure that requires intravenous iodinated contrast should have their metformin therapy held for a few days prior to the procedure and remain well hydrated.  Patient Selection. Based on the landmark results of the UKPDS, obese patients should be considered especially good candidates for metformin therapy. The drug helps to reverse their insulin resistance, peripheral responsiveness to insulin improves, and insulin needs decrease, so hyperinsulinism and its adverse effects, including weight gain, are minimized. The typical candidate is a moderately obese person with type 2 diabetes who has persistent moderate hyperglycemia (fasting glucose between 140 and 240 mg/dL, glycosylated hemoglobin >7.0%) despite a full program of diet and exercise. Early addition of metformin is suggested. Other candidates for metformin include obese patients who do not achieve tight control while taking a sulfonylurea at maximal doses. In this setting, metformin is added to the oral hypoglycemic program to improve control through 7its complementary mode of action. The sulfonylurea dose is reduced to lessen the risk for hypoglycemia. Combination therapy is most effective when initiated before the onset of symptomatic hyperglycemia (fasting glucose >250 mg/dL). Nonobese patients are also reasonable candidates for metformin. Typically, metformin lowers fasting blood glucose by approximately 20%.Patients who started drug therapy with a sulfonylurea and become unresponsive to maximal doses have likely exhausted their beta-cell reserve and can be switched to metformin or considered for exogenous insulin therapy (sometimes in conjunction with metformin). The same pertains to the severely hyperglycemic obese patient (fasting glucose >300 mg/dL). Some diabetologists use metformin to supplement an insulin program in obese type 2 diabetics who require large insulin doses and have difficulty losing weight. The combined program helps to reduce insulin requirements and the appetite stimulation and weight gain that accompany hyperinsulinism. Caution and careful patient monitoring are required when a patient taking exogenous insulin is started on metformin; the insulin requirement may drop considerably, putting the patient at risk for hypoglycemia. Use in pregnancy is not associated with major congenital malformations.

Osteopenia is defined as a T-score between -1.0 and -2.5. A Z score of less than -1.5 suggests a secondary cause of osteoporosis • Osteoporosis: -2.5 or lower • Osteopenia: -1 to -2.5 (lower than normal bone density w/o full osteoporosis) Anxiety treatment- • Treatment for anxiety should reduce symptoms and improve functioning. • Simply listening, being compassionate, and showing respect are important to improving outcomes. Treat comorbid depression and medical conditions that cause anxiety. • There are no large-scale studies of pharmacotherapy for late-life anxiety disorders to guide treatment decisions. • Start low and go slow with medication dosing to avoid risks from drug interactions, because older adults are more likely to take many medications and may have side effects from aging changes in absorption, metabolism, distribution, and excretion of medication. • Evaluate and manage side effects, because as many as 25% of patients stop taking medication in the first 6 months due to side effects. • First-line treatment is the selective serotonin reuptake inhibitors (SSRIs) o citalopram (Celexa), escitalopram (Lexapro), and sertraline (Zoloft). In older adults, they have the least risk of drug interactions, side effects, or worsening existing medical conditions. o Benzodiazepines, including lorazepam (Ativan), alprazolam (Xanax), and clonazepam (Klonopin), are effective according to research but are not the first choice due to the risk of falls and confusion. Research supports referral to psychotherapy for older adults, but this recommendation is limited to GAD and no other anxiety disorders (American Psychiatric Association, n.d.; Cassidy & Rector, 2008; Hollander & Simeon, 2008; Lenze et al., 2005; Lenze & Wetherell, 2009; Mohlman, 2005; National Institute of Mental Health, n.d.; Stanley et al., 2003; Wetherell, Lenze, & Stanley, 2005; Wetherell, Sorrell, Thorp, & Patterson, 2005).

Id. disease severity (airflow limitation) 2. Id. Health impact of COPD 3. Future event risk GOLD COPD stage Spirometry classification (2014) Stage FEV1:FV C Mild Moderate Severe <0.70 <0.70 <0.70 Very severe <0.70 FEV1 > or = 80% of predicted value 50-79% of predicted value 30-49% of predicted value < 30% of predicted value OR < 50% of predicted value with chronic respiratory failure Pulmonary Differential Diagnoses for COPD/ other: Asthma, Bronchogenic carcinoma, Bronchiectasis, TB, CF, Interstitial lung disease, Bronchiolitis obliterans, Alpha-1 antitrypsin deficiency, Pleural effusion, Pulmonary edema, Recurrent aspiration, Tracheobronchomalacia, Recurrent pulmonary emboli, foreign body Non-Pulmonary Differential Diagnoses for COPD/ other: HF, hyperventilation syndrome/ panic attacks, vocal cord dysfunction, undx OSA, Aspergillosis, chronic fatigue syndrome Med management of COPD: 1. Bronchodilators – don’t slow COPD progression; do increase airflow, decreased WOB, Imp. exercise tol. 2. Bronchodilators a. Beta 2 agonists (LABA, SABA) i. MOA- Stimulate Beta2 adrenergic receptors, increasing cyclic AMP & relaxing airway smooth muscle ii. Adverse effects- tachycardia, palpitations, tremors, cramping, insomnia, hypokalemia, prolonged QT, interval hyperglycemia iii. levalbuterol no advantage over albuterol (per her; in real life levalbuterol has less cardiac effects) b. Anticholinergic aka antimuscarinic (long-acting , short-acting ) i. MOA- blocks effect of acetylcholine on muscarinic-type 3 receptors; thus, bronchodilation ii. dry mouth and constipation c. Combinations – slightly increased bronchodilation than either agent alone d. Oral bronchodilator- Theophylline- use if symptoms with inhalers or can’t afford inhalers 14i. Concerns re: toxicity (elderly – hallucination, tachycardia, liver disease, HF) & drug interactions (CYP 1A2, CYP 3A4) ii. Therapeutic range (5-12 mcg/mL) iii. Use slow-release (generic available) 3. Oral corticosteroids a. Poor predictor of long-term response to inhaled steroids in COPD b. Long-term po steroids not recommended for stable COPD. Add inhaled steroids to inh bronchodilators with severe COPD or frequent exacerbation. c. Improve exacerbation frequency, QOL, hospitalization rates- doesn’t slow COPD progression d. Need to use with a LABA for COPD patients 4. Inhaled corticosteroids (ICS) a. ICS monotherapy is only FDA approved for treatment of asthma, not COPD b. Adverse reaction- candidiasis and dysphonia – RINSE after use c. Systemic absorption with high doses (1,000 mcg/d)- bruising, cataracts, reduced bone mineral density. d. Increased pneumonia risk & LABA+ICS no real improvement in exacerbation frequency e. Save ICS for severe COPD - FEV1 of less than 50% predicted 5. Improve spirometry use, Vaccinations (pneumaVAX <55 if smoker/ 65+ if non-smoker), Pulmonary rehabilitation, COPD registry, quit smoking, diet/exercise Agent (Trade name) Albuterol (ProAir, Ventolin, Proventil) Levalbuterol (Xopenex) Salmeterol (Serevent) Formoterol (Perforomist) Arformoterol (Brovana) Ipratropium (Atrovent) Titotropium (Spiriva) Agent class SABA SABA LABA LABA LABA SAMA LAMA Albuterol + Ipratropium (DuoNeb) SABA+SAM A Fluticasone/ salmeterol (Advair) Budesonide/ formoterol (Symbicort) Mometasone/ formoterol (Dulera) Inhaler type (mcg/puff) Dose/frequency MDI (Metered dose) (90) 1-2 inh Q4-6 hrs PRN MDI (45) 1-2 inh Q4-6 hrs PRN DPI (Dry powder) (50) 1 inh BID DPI (12) 1 inh BID N/A MDI (17) 2 puffs q6h DPI (18) 1 inh (DPI)/2 inhalations (SMI-soft mist) QD MDI (90+18) 1 inh QID ICS + LABA DPI (100/250/500+50) 1 inh BID ICS + LABA MDI (80/160 + 4.5) 2 inh BID ICS + LABA MDI (100/200 + 5) NOT FDA ap for COPD (just asthma) Lesson Link to GOLD guidelines https://goldcopd.org/ and https://lms.courselearn.net/lms/CourseExport/files/bb47abfc-cc87-411a-8365- 8471f7735d90/Asthma_and_COPD.pdf differentiating asthma and COPD Great COPD link: https://www.healthquality.va.gov/guidelines/CD/copd/VADoDCOPDPocketCard.pdf 15 Nebulizer Solution 0.63, 1.25 mg/3 mL; 2.5 mg/0.5 mL; 2.5 mg/3mL 0.31, 0.63, 1.25 mg/3mL N/A 20 mcg/ 2 mL 15 mcg/2 mL 0.5 mg/2.5 mL N/A 2.5+0.5 mg/3mLSpirometry measures: Flow loops indicate validity of results, but flow loops WILL NOT be on boards or tests – just included them because they help make sense of the changes in values Spirometry- tech enters age, weight, race, sex & height - when looking at results you don’t need this- it’s pre- calculated in the results Spirometry Results and GOLD classifications: Normal values 16 GOLD classifications post bronchodilatorFEV1 (step 2 grade severity) FEV1 80% to 120% GOLD 1 mild FEV1 > = 80% predicted GOLD 2 moderate FEV1 50% to 79% predicted GOLD 3 severe FEV1 30% to 49% predicted GOLD 4 Very severe FEV1 < 30% predicted FVC FEV1/FVC ratio (step 1 = determine if obstruction) 80% to 120% > 70% (no obstruction) Step 3- Reversibility? A. Test spirometry pre and post bronchodilator (SABA or SAMA) B. Post testing is 10-15 minutes after SABA/SAMA C. ATS criteria: “significant response” is > = 12% FEV1 or FVC improvement and an absolute improvement of > = 0.2 L D. : “significant response” indicates asthma (due to reversibility) Interpreting PFT results Step 1: Check the ratio to see if obstruction exists. Is FEV1/FVC low? <70 = Obstructive defect or COPD Step 2: grade severity with FEV1 post bronchodilation to classify by GOLD criteria GOLD 1 mild FEV1 > = 80% predicted GOLD 2 moderate FEV1 50% to 79% predicted GOLD 3 severe FEV1 30% to 49% predicted GOLD 4 Very severe FEV1 < 30% predicted Step 3- Reversibility Is there a 12% FEV1 or FVC increase post bronchodilation? Yes = reversible TYPICAL PNEUMONIA SYNDROME- (see lesson;Hutt & Kramer, 2002; Furman, Rayner, & Tobin, 2004): Fast fever, cough = new/worse; purulent sputum (rusty, green), pleuritic CP; Lobar infiltrate on chest X-ray (day 2+ - may become infiltrates) indicating pulm consolidation; Consider Streptococcus pneumoniae & other bacterial pathogens ATYPICAL PNEUMONIA- (see lesson; Hutt & Kramer, 2002; Furman, Rayner, & Tobin, 2004): Gradual fever, dry cough, min secretions, HA, malaise, myalgias, pharyngitis, GI distress. crackles (rales); Abnormal or patchy chest X-ray pattern. Consider mycoplasma or chlamydia, pneumoniae, or oral anerobes. Viral pneumonia may be atypical in presentation. Helpful images below from this video (Thanks to Nicole Popovich-Johnson): youtube spirometry video link 17FVC essentially same as VC FVC essentially same as VC. In obstructive lung disease, the graph (image above left) shifts to the left due to increased RV (because of air trapping); VC stays same but TLC increases due to increased FRC and increased RV. line R upper image below – Dotted line is the normal lung, solid lines (shifted left) are obstructive lung spirometry. Restrictive lung disease = lungs don’t fully expand; reduced lung volume & TLC (sarcoidosis, pneumoconiosis, Interstitial lung disease i.e. pulmonary fibrosis; Neuromuscular disease, i.e. MD or ALS); graph shifts to right to due to decreased TLC; In restrictive FEV1/FVC is not as affected as in obstructive disorders ******************************************************************************************* 18Week 2 notes: BPH and BP: Alpha blockers include doxazosin mesylate (Cardura), prazosin hydrochloride (Minipress), and terazosin hydrochloride (Hytrin); If we start on alpha blocker, they should follow up in 4-6 weeks. PROSCAR (finasteride): inhibitor of steroid Type II 5α-reductase, an intracellular enzyme that converts the androgen testosterone into 5α- dihydrotestosterone (DHT).
