NR 601 FINAL EXAM REVIEW

NR 601 COMPREHENSIVE FINAL EXAM STUDY GUIDE AND PRACTICE QUESTIONS 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). The test should be performed in a laboratory using a method that is NGSP certified and standardized to the DCCT assay.* • In a patient with classic symptoms of hyperglycemia or hyperglycemic crisis, a random plasma glucose ≥200 mg/dL (11.1 mmol/L). • Urinary incontinence- • Involuntary loss of urine from the bladder ▪ So common in women many consider it normal ▪ Common in older men w/ enlarged prostate o Can affect quality of life o Significance-One of the most common complains w/ older adults, Distress & embarrassment, Cost burden to pt & society as a whole, Not life-threatening, may effect QOL, PCP essential to educating individuals o Epidemiology- Increased prevalence w/ age in men & women, Nursing home population – 40-70%, Often a factor in placement ▪ URGENCY UI is greater in men ▪ STRESS UI is greater in women o Terminology ▪ UI- Unintentional voiding, loss or leakage of urine ▪ Continuous incontinence-Continuous loss or leak of urine ▪ Increased daytime frequency-More frequent during day than considered normal ▪ Nocturia-Interruption of sleep one or more times due to the need to urinate – increases in frequency after age 50 ▪ Urgency-Sudden, compelling desire to pass urine that’s difficult to prevent ▪ Overactive bladder syndrome- Urgency, frequency, nocturia w/ or w/o incontinence o Risk Factors-Aging,Obesity,Smoking, Caffeine,Uncontrolled DM, Constipation,Use of diuretics o Risk Factors by gender-Women:Aging, obesity, smoking, caffeine intake, DM, pregnancy, multiparity, estrogen deficiency, hx of pelvic surgery, diuretics Men:Aging, obesity, smoking, caffeine, DM, prostate dx, hx of prostate surgery, hx of UTIs, diuretics o Physical changes w/ aging that contribute to UI ▪ Lower urinary tract-Detrusor muscle over activity,Decrease in detrusor contractility, Increase in post void residual,Decrease in urethral blood flow ▪ Women – decrease in urethral closure pressure,Low estrogen following menopause - leads to atrophy of ureteral mucosal epithelium & increase in urethral sensation ▪ Men can experience constriction of urethra due to BPH which may result in bladder outlet obstructing symptoms - Initial clinical workup for UI in Men o PMH, PE, UA, DRE: Eval of prostate,PSA w/ new onset in men - UI workup in women:Exclude underlying causes,PMH, PE, UA, Pelvic exam, vaginal exam, perineal, Identify estrogen status of pt, Pelvic prolapse, fistula, -Cough test, Integrity of pelvic musculature, leaking of urine ▪ Full bladder ▪ Standing position ▪ Asked to cough ▪ If urine leak is observed, stress incontinence is confirmed - Red flags in males o Higher level of suspicion for serious diseases, Refer to urology if Previous pelvic surgery, Pelvic radiation, Pelvic pain, Severe incontinence, Severe UTI symptoms, Recurrent urologic infection,Abnl Prostate exam,Elevated PSA o Be alert to these with NEW ONSET UI- Hematuria,Pelvic pain,Abdominal mass, Dysuria, Proteinuria, Glucosuria, CVA tenderness,Nodular prostate,Any new neuro symptoms - Goals of treatment: Reduce symptoms, Improve QOL, Increase social activity, Reduce leakage volumes, increase dryness, use less protection; Increase independence in incontinence management; Decrease caregiver burden - 1st line management guidelines o AHRQ guidelines for management of UI in women ▪ Behavioral therapy ▪ Lifestyle modification ▪ Try for 3 months before pharm management o Weight loss, Smoking cessation(Tobacco is a bladder irritant),Less coughing o Dietary changes-Alcohol, soda, coffee with or without caffeine, acidic foods and spicy foods o Maintain adequate fluid balance to reduce constipation, provide adequate flow to kidneys - Behavioral strategies:Bladder training, Bladder control strategies,Timed voiding,Kegels, Pelvic floor training - 2nd line management - Medication o Antimuscarinic medication: 1st line for women ▪ Block the parasympathetic muscarinic receptors ▪ Inhibit involuntary detrusor contractions ▪ Side effects due to the effects on other muscarinic receptors o Outcomes unpredictable and side effects common o Common s/e: Dry mouth**, Blurred vision, Constipation,Nausea,Dizziness, Headache o AntimuscarinicsMechanism of action ● Blocks acetylcholine at muscarinic receptors, relaxes bladder smooth muscle, inhibits involuntary detrusor contractions (anticholinergic) ● CYP3A4 substrates ▪ Indications: UI and OAB ▪ Contraindications: Untreated/uncontrolled narrow angle glaucoma,Gastric retention, Urinary retention ▪ Precautions:CNS depression,Caution in elderly ● Renal dosing o CrCl <30 o Beta 3 Adrenergic Agonist – Mirabegron (Myrbetriq) ▪ Also approved for UI and OAB ▪ Clinical trials – significant reduction in incontinence and micturations ● No anticholinergic s/e ▪ Mech of action
