NCLEX #4
What diagnostic test do we need to assess?
Blood glucose levels (70-110 fasting) HgbA1C
After several diagnostic tests, a client is diagnosed with diabetes insipidus. The nurse performs an assessment on the client, knowing that which symptom is most indicative of this disorder? A.Fatigue B.Diarrhea C.Polydipsia D.Weight gain
C - (eliminate option 1 because of the word most) DI is characterized by polydipsia and polyuria, low specific urine gravity, anorexia and wt loss not wt gain
The client with DKA is given normal saline IV and regular insulin. In addition to hourly blood glucose monitoring, the nurse would look to what assessment data as early signs of clinical improvement? A.Respiratory rate of 12 to 15 and normal BP in standing position B.Temperature and pulse in normal range C.Improved level of consciousness (LOC) and decreasing urine output D.Client eats a full and respiratory rate is normal.
C - LOC responds quickly to changes in pH and restoration of fluids and electrolytes. UO decreases as hyperglycemia improves; resp system takes a few hours to respond to changes and will come down to a high normal rather than a low normal. Dehydration is usually so severe that it takes hours to rehydrate and increase strength of pulse.
What risks are associated with someone with DM
Heart, (HTN, CAD, PVD) Renal, Neuro, retinopathy, mephropathy, neuropathy
Types of Short Acting Insulin
Humulin R Novolin R = regular short
What management and treatment interventions
Diet Medications Insulin
Chronic Kidney Disease (CKD)
Progressive, irreversible loss of kidney function GFR ≤ 60 mL/min for 3 months or longer Stages 1-5
Creatinine
0.6 - 1.3 mg/dL
Nephrotoxic Drugs/Substances
Antibiotics - Amphotericin, Methicillin, Rifampin, Sulfonamides, Tetracycline, Vancomycin, Gentamycin (and other mycins) Antineoplastics - Cisplatin, Methotrexate NSAIDS - Celecoxib, Ibuprofen, Ketoralac, Naproxen Others - Captopril, Cyclosporine, Quinine Radiographic Contrast dyes Heavy Metals - Arsenic, Copper, Gold salts, Lead
treatment for Renal Calculi
Assess, monitor I &O, push fluids >3L / day; heat to flank, analgesics, strain urine, Surgery - cystoscopy (for stones in bladder); Extracorporeal shock wave lithotripsy (ESWL) (ultrasonic waves used to break up stones); Percutaneous Lithotripsy; Ureterolithotomy - surgical procedure to remove stone in ureter
The client is admitted with metabolic acidosis secondary to DKA. Which of the following does the nurse formulate as the priority nursing diagnosis? A.Impaired Urinary Elimination related to reduced output and muscle function B.Deficient fluid volume related to high urine output C.Ineffective breathing pattern related to hyperventilation D.Anxiety related to fears of long-term outcomes and discomfort
B The severe dehydration is highest priority, hyperventilation is a manifestation of the acidosis and does not reflect an ineffective breathing pattern
In developing a plan about hypoglycemia for a newly diagnosed Type I diabetic, which sign or symptom should the nurse include? A.Shakiness B.Increased thirst C.Fever D.Fruity breath
A - s/s of hypoglycemia include shakiness, sweating, pale cool skin, and irritability
Why should the client taking glucocorticosteroids as replacement therapy or to treat an existing disease never miss a dose or suddenly stop taking the medication?
Clients on long-term and high dose glucocorticoid therapy are at risk for suppression of Adrenocorticotropic hormone which can suppress cortisol, therefore the patient can go into acute adrenal insufficiency (Addisonian crisis). Clinical manifestations are hypotension, tachycardia, dehydration, hyponatremia, hyperkalemia, hypoglycemia, fever, weakness, confusion, and shock.
Polycystic Kidney Disease
Cyst of the kidneys Genetic autosomal disease Clinical Manifestations Often asymptomatic til 30's Flank, lumbar, abd pain; fever, chills, recurrent UTIs, hematuria, proteinuria, pyuria, Calculi, HTN, palpable abd mass and enlarged kidneys Interventions Increase Na and H20 intake Bedrest if cyst ruptures and bleeding occur Manage symptoms for pain, fever, UTI Prepare for dialysis, renal transplant as leads to ESRD
Lispro insulin (Humalog) is prescribed for the client, and the client is instructed to administer the insulin before meals. When should the nurse instruct the client to administer the insulin? A.45 minutes before eating B. 60 minutes before eating C.90 minutes before eating D. Immediately before eating
D. Lispro insulin acts more rapidly than regular insulin and has a shorter duration of action. The effect of lispro insulin begins within 25 minutes after subcutaneous injection, peaks in 0.5 to 1.5 hours, and has a duration of action of approximately 5 hours. Because of its rapid onset, it can be administered from 15 minutes to immediately before eating. In contrast, regular insulin is generally administered 30 minutes before meals.
Treatment
Diet (low carb but complex carbs ok in mod amts; avoid simple sugars)) Alcohol can lower BG and can cause hypoglycemia Oral antidiabetic meds (type II only) Insulin therapy Only short acting insulins given IV (Regular most commonly but now Lispro, Aspart, and Glulisine) other routes subq; insulin pumps (know how to adm insulin)
signs of hypoglycemia
Dizziness Moodiness Inability to concentrate Slurred Speech Shakiness
The client with SIADH is upset at not being able to drink fluids whenever she wants. How should you respond?
Explain to the patient their diagnosis. And that fluid needs to be restricted until electrolyes (sodium) is restored and fluid volume is normal. Teach of s/s Educate on proper fluid restrictions and sources of fluid to measure Weigh daily and report weight gain > 2 lbs/day Diet w/ sodium and potassium supplements if diuretics are prescribed Medication education
Causes of Renal Calculi
Family, high calcium, vitD, protein, oxalate, purine, or alkali diets; urinary stasis, dehydration, hypercalcemia, hyperparathyroidism, elevated uric acid (gout)
Fasting
Fasting means after not having anything to eat or drink (except water) for at least 8 hours before the test. This test is usually done first thing in the morning, before breakfast. Diabetes is diagnosed at fasting blood glucose of greater than or equal to 126 mg/dl.
SIADH
Fluid volume excess, increased BP, crackles in lung fields, distended jugular veins, taut skin, Intake > output, small amount of concentrated urine, vomiting, fatigue, nausea, muscle aches, abdominal cramps, weight gain w/o edema, excessive thirst As serum sodium levels decline leads to cerebral edema, altered level of consciousness, seizures, Headache, anorexia, & coma.
What to do when a patient in hypoglycemic?
Give them simple sugars! Orange Juice or Grape Juice Glucose tabs Glucose Tubes
Protein (24 hour urine)
Less than 150 mg/ 24 hours
Type 1 Diabetics
NEED INSULIN Diet and exercise
Types of Intermediate Acting Insulin
NPH ; 70/30
Peritoneal Dialysis
Peritoneal Dialysis •Use of peritoneal access catheter placed in ant abd wall •Allow immediate use once cath inserted •A cycle involves: inflow, dwell, and drain •Dialysate volumes from 1L - 3L, high glucose concentration increases osmotic forces. •Risk - peritonitis, abd pain with too rapid infusion, hyperglycemia, exit site infection, hernias, pulmonary complications, protein loss
Acute Kidney Injury
Rapid loss of kidney function Potentially reversible depending to severity of damage, however high mortality rates
Anything greater than 6.5
Means they are a diabetic
Stages of Chronic Kidney Disease
Stage 1 at risk GFR >90 dx and treat CVD; slow progression Stage 2: Mild CKD - 60-89 Stage 3: Mod 30-59 GFR evaluate and treat complications Stage 4: Severe GFR 15-29 preparation for kidney transplant Stage 5: ESKD <15mL dialysis or replacement required
Diabetes Insipidus Treatment
Monitor I&O (report UO > 200 ml/hr for 2 hours) Daily weights Monitor urine specific gravity Encourage fluid intake greater than urine output Use skin protective barriers Medication therapy as ordered Nursing Diagnosis: fluid volume deficit; risk for constipation, risk for impaired skin Integrity
Assessment
changes in weight, nutrition pattern, elimination pattern, VS, skin, wound healing, changes in vision, sensory perception (neuropathy), decreased activity tolerance. Polyuria, polydipsia, poly phagia, wt loss commonly seen in Type I Polyuria, polydipsia, blurred vision, fatigue, numbness, skin infections, and polyphagia in type II
Diagnosing Diabetes
The A1C test measures your average blood glucose for the past 2 to 3 months. The advantages of being diagnosed this way are that you don't have to fast or drink anything. Diabetes is diagnosed at an A1C of greater than or equal to 6.5%
Cystitis
or commonly referred to as UTI painful urination, frequency, and urgency are common s/s of cystitis or bladder infection. Also urine may have a foul odor and appear cloudy. Lower abd or back pain, hematuria, malaise, fever, chills, n/v, elevated WBC (Change in mental status is common in elderly) Caused by allergens, irritants (soaps, perfumes), urinary stasis, indwelling caths, sexual intercourse, use of spermicides
What assessment findings for a client with DM?
Three P's - Polyuria, Polydipsia, Polyphagia
Treatment for DKA
Treatment: - IVF rehydration (NS bolus then 200-500 mL/hr until stabilized); insulin (typically reg insulin drip); electrolytes, supportive care may need mechanical ventilation for resp failure and vasopressors for hypotension. Make sure you monitor LOC as cerebral edema may develop w/ NS bolus and insulin can cause hypoglycemia KCL replacement once acidosis is reversed and insulin is administered because K shifts into the instracellular compartment and serum level can drop quickly. Necessary to monitor ECG and cardio status Restore fluids loss, electrolytes, and glucose. Monitor I&Os; BG, Urine, O2, and resp pattern
What is the difference between Type I and Type II
Type I - early onset typically children Type II - adult onset common in African Americans and Native Americans

Usually reversible with high dose corticosteroids and increased immunosuppressive agents •Chronic - immunosuppressive agents and may need retransplantation if necessary.
Urinalysis
Urine Specific Gravity - 1.016 - 1.022; Color; pH (5-9); protein; glucose; ketones; & Blood
Diagnostic Findings for Diabetes Insipidus
Urine specific gravity < 1.005 Urine osmolality <300 Positive water deprivation test Serum sodium > 145mEq/L Identify the primary cause of DI
Phases of AKI

Oliguric Phase - lasts 8-15 days; sudden decrease in urine output; s/s HTN, edema, dysrhythmias, HF, pulm edema, anorexia, n/v, Kussmauls resp, changes in LOC, pericarditis 3. Diuretic Phase - slow increase of urine output; dehydration; hypotension, tachycardia; LOC improves 4. Recovery Phase - slow process may take 1-2 years. Urine volume returns to normal; strength increases, recover to near normal values
Primary Functions of Kidney
1. Regulate the volume and composition of extracellular fluid 2. Excrete waste products from the body 3. Maintain acid-base balance 4. Excrete bacterial toxins, water soluble drugs, and drug metabolites 5. Secrete renin to regulate the blood pressure and erythropoietin to stimulate RBC productions 6. Synthesize Vit D for calcium absorption and regulate parathyroid hormone
Risk Factors for Type II Diabetes
age, family history, ethnic group, social class, fetal nutrition and early growth pattern, diet (SFA), inadequate physical activity, central obesity, metabolic syndrome
Pyelonephritis Treatment
assess monitor nutritional status; I & O; fluid and electrolyte balances, VS, increase fluid intake to 2 L; antipyretics as needed, antibiotics as needed, (mild may be treated at home, severe hospitialization for 24-48 hr with IV antibiotics) surgery for extreme cases as it may lead to septic shock, CKD, hypertension
Diagnostics
blood glucose; serum ketones, elevated HgbA1C (range: 5.5-7); two-hour glucose tolerance test; urine for glucose and ketones
Treatment of Acute Kidney Injury
Acute Kidney Injury
Alcohol and diabetes
client is at risk for hypoglycemia. Body looks at alcohol as toxin. 2 drink maximum (12oz of beer, 5 oz of wine, 1 oz hard liquor)
An external insulin pump is prescribed for a client with diabetes mellitus and the client asks the nurse about the functioning of the pump. The nurse bases the response on which information about the pump? A.Is timed to release programmed doses of short-duration or NPH insulin into the bloodstream at specific intervals B.Continuously infuses small amounts of NPH insulin into the bloodstream while regularly monitoring blood glucose levels C.Is surgically attached to the pancreas and infuses regular insulin into the pancreas, which in turn releases the insulin into the bloodstream D.Gives a small continuous dose of short-duration insulin subcutaneously, and the client can self-administer a bolus with an additional dose from the pump before each meal
A - An insulin pump provides a small continuous dose of short-duration (rapid or short-acting) insulin subcutaneously throughout the day and night, and the client can self-administer a bolus with an additional dose from the pump before each meal as needed. Short-duration insulin is used in an insulin pump. An external pump is not attached surgically to the pancreas.
Glimepiride (Amaryl) is prescribed for a client with diabetes mellitus. The nurse instructs the client to avoid consuming which food while taking this medication? A.Alcohol B.Organ meats C.Whole grain cereals D.Carbonated beverages
A - When alcohol is combined with glimepiride (Amaryl), a disulfiram-like reaction may occur. This syndrome includes flushing, palpitations, and nausea. Alcohol can also potentiate the hypoglycemic effects of the medication. Clients need to be instructed to avoid alcohol consumption while taking this medication. The items in options 2, 3, and 4 do not need to be avoided.
A client with new onset type I DM asks why he needs to check his blood glucose level so frequently. The nurse explains that frequent coverage with insulin to keep the blood glucose level between 70-120mg/dL is important for which reason? A.Chronic elevated blood glucose levels damage cells and cause multiple organ damage B.High glucose levels cause the body to use proteins for energy, causing lactic acidosis C.Early identification of hypoglycemia before the onset of symptoms is easier to treat D.Carbohydrates are constantly being converted to glucose and transported in the bloody by insulin.
A - chronic hyperglycemia leads to retinopathy, nephropathy, and neuropathy. Lactic acidosis occurs with DKA and metabolism of fat. Insulin is needed to carry glucose across the cell membrane into the cell not to be transported in the blood.

Insulin glargine (Lantus) is prescribed for a client with diabetes mellitus. The nurse should tell the client that it is best to take the insulin at which time? A.At bedtime B.1 hour after each meal C.15 minutes before the morning and evening meal D.Before each meal, on the basis of blood glucose level
A. Insulin glargine is a long-acting recombinant DNA human insulin that is used to treat type 1 and type 2 diabetes mellitus. It has a 24-hour duration of action and is administered once a day, usually at bedtime. Therefore, options 2, 3, and 4 are incorrect times.
The nurse is teaching a client how to mix regular insulin and NPH insulin in the same syringe. Which action, if performed by the client, indicates the need for further teaching? A.Withdraws NPH insulin first B.Withdraws the regular insulin first C.Injects are into the NPH insulin vial first D.Injects an amount of air equal to the desired dose of insulin into each vial
A. When preparing a mixture of short-acting insulin such as regular insulin with another insulin preparation, the short-acting insulin is drawn into the syringe first. This sequence will avoid contaminating the vial of short-acting insulin with insulin of another type. Options 2, 3, and 4 identify correct actions for preparing NPH and short-acting insulin.
The nurse is caring for a client who is taking 4 units of regular insulin and 30 units of NPH insulin at 8:00 am. The nurse keeps which of the following in mind regarding this regimen? Select all that apply. A.Assess client for hypoglycemia shortly before lunch B.Assess client for hypoglycemia at dinnertime C.Shake vial of insulin to disperse insulin particles evenly D.Administer room temperature insulin only E.Neither insulin can be administered intravenously
A.Assess client for hypoglycemia shortly before lunch B.Assess client for hypoglycemia at dinnertime D.Administer room temperature insulin only
Which of the following assessments may be related to the low serum sodium seen in patients with syndrome of inappropriate secretion of antidiuretic hormone? A.Central nervous system changes B.High urinary output C.Hypotension D.Weight loss
A.Central nervous system changes
A client is taking Humulin NPH insulin and regular insulin every morning. The nurse should provide which instructions to the client? Select all that apply. A.Hypoglycemia may be experienced before dinnertime. B.The insulin dose should be decreased if illness occurs. C.The insulin should be administered at room temperature. D.The insulin vial needs to be shaken vigorously to break up the precipitates. E.The NPH insulin should be drawn into the syringe first, then the regular insulin.
1.Hypoglycemia may be experienced before dinnertime. 3.The insulin should be administered at room temperature. Humulin NPH is an intermediate-acting insulin. The onset of action is 1.5 hours, it peaks in 4 to 12 hours, and its duration of action is 24 hours. Regular insulin is a short-acting insulin. Depending on the type, the onset of action is 0.5 hour, it peaks in 2 to 5.5 hours, and its duration is 5 to 8 hours. Hypoglycemic reactions most likely occur during peak time. Insulin should be at room temperature when administered. Clients may need their insulin dosages increased during times of illness. Insulin vials should never be shaken vigorously. Regular insulin is always drawn up before NPH.
Creatinine (24 hour urine)
15-25 mg/kg in 24 hours
Creatinine Clearance
70-135 mL/min
BUN
8-25 mg/dL;
A client with diabetes mellitus visits a health care clinic. The client's diabetes mellitus previously had been well controlled with glyburide (DiaBeta) daily, but recently the fasting blood glucose level has been 180 to 200 mg/dL. Which medication, if added to the client's regimen, may have contributed to the hyperglycemia? A.Prednisone B.Phenelzine C.Atenolol D.Allopurinol
A.Prednisone Prednisone may decrease the effect of oral hypoglycemics, insulin, diuretics, and potassium supplements. Option 2, a monoamine oxidase inhibitor, and option 3, a b-blocker, have their own intrinsic hypoglycemic activity. Option 4 decreases urinary excretion of sulfonylurea agents, causing increased levels of the oral agents, which can lead to hypoglycemia.
Who has a higher chance of developing Type II Diabetes?
African Americans, Hispanics and Native Americans
Diagnostic Findings in DKA
BG greater than 300; plasma pH less than 7.35; HCO3 less than 15 mEq/L; serum ketones, urine +ketones and glucose; changes in serum sodium and hyperkalemia.
Post-renal caused by
BPH, renal/kidney stones, tumors, cystitis
Acute Kidney Injury Phases
Begins with onset and ends with oliguria (100-400 ml/24 hrs) with or w/o diuretics lasts 1-3 wks; Diuresis begins when kidney starts to recover and can last 2-6 wks; Recovery continues until kidney function is fully restored
A client received 20 units of Humulin N insulin subcutaneously at 08:00. At what time should the nurse plan to assess the client for a hypoglycemic reaction? A.10:00 B.11:00 C.17:00 D.23:00
C. Humulin N is an intermediate-acting insulin. The onset of action is 1.5 hours, it peaks in 4 to 12 hours, and the duration of action is 16 to 24 hours. Hypoglycemic reactions most likely occur during peak time.
A client is brought to the emergency department in an unresponsive state, and a diagnosis of hyperglycemic hyperosmolar state (HHS) is made. The nurse would immediately prepare to initiate which anticipated health care provider's prescription? A.Endotracheal intubation B.100 units of NPH insulin C.IV of NS D.IV infusion of sodium bicarbonate
C.The primary goal of treatment in hyperglycemic hyperosmolar state (HHS) is to rehydrate the client to restore fluid volume and to correct electrolyte deficiency. Intravenous fluid replacement is similar to that administered in diabetic ketoacidosis (DKA) and begins with IV infusion of normal saline. Regular insulin, not NPH insulin, would be administered. The use of sodium bicarbonate to correct acidosis is avoided because it can precipitate a further drop in serum potassium levels. Intubation and mechanical ventilation are not required to treat HHS.
Symptoms of DKA
Dehydration; metabolic acidosis, nausea, vomiting, excessive thirst, malaise, polyuria, Kussmual respirations, dry skin with poor turgor, abd pain, hypotension, weak thready pulse, and can lead to coma and death!!!
Biguanides
