Diminished ability to concentrate urine, associated with aging of the urinary system, is attributed to a. a decrease in bladder sensory receptors b. a decrease in the number of functioning nephrons c. decreased function of the loop of Henle and tubules d. thickening of the basement membrane of Bowman's capsule

1. Correct answer: c Rationale: Older adults have decreased function of the loop of Henle and tubules, which results in the loss of normal diurnal excretory pattern because of a decreased ability to concentrate urine and because of less concentrated urine.

Formation of urine is done in the folloing:

1. Filtration at the glomerulus 2. Absorption into the peritubular capillaries 3. Reabsorption into the tubule for excretion in urine

The patient with type 1 diabetes is having a seizure. Which medication would the nurse anticipate will be administered first? A IV dextrose solution B IV diazepam (Valium) C IV phenytoin (Dilantin) D Oral carbamazepine (Tegretol)

A IV dextrose solution Rationale: This patient's seizure could be caused by low glucose, so IV dextrose solution would be given first to stop the seizure. IV diazepam, IV phenytoin, and oral carbamazepine would be used first to treat seizures from other causes such as head trauma, drugs, and infections. These drugs will be tried if the IV dextrose is ineffective.

A patient with suspected renal insufficiency is scheduled for a creatinine clearance diagnostic test. Which instructions would be appropriate for the nurse to provide to the patient? A "Empty your bladder and discard the urine; then save all urine for 24 hours." B "Your blood creatinine level will be tested after you eat a high-protein meal." C "This test should not be performed if you have allergies to iodine or shellfish." D "A sterile container must be used to store the urine during the colle

A "Empty your bladder and discard the urine; then save all urine for 24 hours." Rationale: The patient should discard the first urination when this test is started. Urine should be saved from all subsequent urinations for 24 hours. Creatinine clearance testing does not involve the injection of contrast dye. A serum creatinine is determined during the 24-hour period and used in the calculation to determine creatinine clearance. Consumption of a high-protein meal is not indicated. Sterile containers would be indicated if cultures are performed to determine the presence of microorganisms.

A patient with a history of recurrent urinary tract infections has been scheduled for a cystoscopy. What teaching point would the nurse emphasize before the procedure? A "You might have pink-tinged urine and burning after your cystoscopy." B "You'll need to refrain from eating or drinking after midnight the day before the test." C "The morning of the test, you will drink some water that contains a contrast solution." D "You'll need a urinary catheter before the cystoscopy, and it will be in plac

A "You might have pink-tinged urine and burning after your cystoscopy." Rationale: Pink-tinged urine, burning, and frequency are common after a cystoscopy. The patient does not need to be NPO before the test, and contrast media is not needed. A cystoscopy does not always necessitate catheterization before or after the procedure.

The nurse is preparing a patient for an intravenous pyelogram (IVP). What is a priority action by the nurse? A Administer a cathartic or enema. B Assess patient for allergies to penicillin. C Keep the patient NPO for 4 hours pre-procedure. D Tell the patient a metallic taste be present during the procedure.

A Administer a cathartic or enema. Rationale: Nursing responsibilities in caring for a patient undergoing an IVP include administration of a cathartic or enema to empty the colon of feces and gas. The nurse will also assess the patient for iodine sensitivity; keep the patient NPO for 8 hours before the procedure; and advise the patient that warmth, a flushed face, and a salty taste during injection of contrast material may occur.

Which findings will the nurse expect when caring for a patient with chronic kidney disease (CKD)? (Select all that apply.) A Anemia B Dehydration C Hypertension D Hypercalcemia E Increased fracture risk F Elevated white blood cells

A Anemia C Hypertension E Increased fracture risk Rationale: When the kidney fails, erythropoietin is not excreted, so anemia is expected. Dehydration and hypercalcemia are not expected in chronic renal disease. Fluid volume overload with hypertension and hypocalcemia are expected. Hypocalcemia from chronic renal disease stimulates the parathyroid to release parathyroid hormone, causing calcium liberation from bones increasing the risk of pathological fracture. Although impaired immune function should be expected, elevated white blood cells would indicate inflammation or infection not associated with chronic renal failure itself but a complication.

A patient with stage 3 chronic kidney disease (CKD) is being taught about a low-potassium diet. The nurse recognizes the patient understands the diet when the patient selects which foods to eat? A Apple, green beans, and a roast beef sandwich B Granola made with dried fruits, nuts, and seeds V Watermelon and ice cream with chocolate sauce D Bran cereal with ½ banana and milk and orange juice

A Apple, green beans, and a roast beef sandwich Rationale: When the patient selects an apple, green beans, and a roast beef sandwich, the patient shows understanding of the low-potassium diet. Granola, dried fruits, nuts and seeds, milk products, chocolate sauce, bran cereal, banana, and orange juice all have high levels of potassium, at or above 200 mg per 1/2 cup.

A patient with stage 2 chronic kidney disease is scheduled for an outpatient diagnostic procedure using contrast media. Which priority action would the nurse perform? A Assess the patient's hydration status. B Insert a urinary catheter for the expected diuresis. C Evaluate the patient's lower extremities for edema. D Check the patient's urine for the presence of ketones.

A Assess the patient's hydration status. Rationale: Preexisting kidney disease is the most important risk factor for the development of contrast-associated nephropathy and nephrotoxic injury. If contrast media must be administered to a high-risk patient, the patient needs to have optimal hydration. The nurse should assess the hydration status of the patient before the procedure is performed. Indwelling catheter use should be avoided whenever possible to decrease the risk of infection.

A postoperative patient had a urinary catheter. Eight hours after catheter removal and drinking fluids, the patient has not been able to void. What test should the patient have first to assess for urinary retention? A Bladder scan B Cystometrogram C Residual urine test D Kidneys, ureters, bladder (KUB) x-ray

A Bladder scan Rationale: If the patient is unable to void, the bladder may be palpated for distention or percussed for dullness if it is full, or a bladder scan may be done to determine the approximate amount of urine in the bladder. A cystometrogram visualizes the bladder and evaluates vesicoureteral reflux. A KUB x-ray delineates size, shape, and positions of kidneys and possibly a full bladder. Neither of these would be useful in this situation. A residual urine test requires urination before catheterizing the patient to determine the amount of urine left in the bladder, so this assessment would not be helpful for this patient.

Which assessment findings would alert the nurse that the patient has entered the diuretic phase of acute kidney injury (AKI)? (Select all that apply.) A Dehydration B Hypokalemia C Hypernatremia D BUN increases E Urine output increases F Serum creatinine increases

A Dehydration B Hypokalemia E Urine output increases Rationale: The hallmark of entering the diuretic phase is the production of copious amounts of urine. Dehydration, hypokalemia, and hyponatremia occur in the diuretic phase of AKI because the nephrons can excrete wastes but not concentrate urine. Serum BUN and serum creatinine levels begin to decrease.

A patient was admitted 2 weeks ago after multiple traumatic injuries in a motor vehicle collision. The patient now has a serum creatinine at 3.9 mg/dL and blood urea nitrogen (BUN) of 100 mg/dL. Which medication, if ordered by the health care provider, would the nurse question? A Gentamicin B Nitrofurantoin C Acetaminophen D Morphine sulfate

A Gentamicin Rationale: Elevated serum creatinine and BUN indicate renal insufficiency or acute kidney injury. All medications should be evaluated for nephrotoxic potential. Many drugs are known to be nephrotoxic (see Table 49.3); gentamicin is a potential nephrotoxic agent.

The patient has rapidly progressing glomerular inflammation. Weight has increased and urine output is steadily declining. What is the priority nursing intervention? A Monitor the patient's cardiac status. B Teach the patient about hand washing. C Obtain a serum specimen for electrolytes. D Increase direct observation of the patient.

A Monitor the patient's cardiac status. Rationale: The nurse's priority is to monitor the patient's cardiac status. With the rapidly progressing glomerulonephritis, renal function begins to fail and fluid, potassium, and hydrogen retention lead to hypervolemia, hyperkalemia, and metabolic acidosis. Excess fluid increases the workload of the heart, and hyperkalemia can lead to life-threatening dysrhythmias. Teaching about hand washing and observation of the patient are important nursing interventions but are not the priority. Electrolyte measurement is a collaborative intervention that will be done as ordered by the health care provider.

A patient has been receiving scheduled doses of phenytoin and develops diplopia. Which additional findings would the nurse expect? A Nystagmus and confusion B An aura or focal seizure C Abdominal pain and cramping D Irregular pulse with palpitations

A Nystagmus and confusion

A patient was just diagnosed with Huntington's disease. The patient's adolescent child is upset about their parent's diagnosis. What is the nurse's best response? A Provide emotional and psychologic support. B Encourage him to get diagnostic genetic testing. C Explain that cognitive deterioration will be treated with counseling. D Teach that chorea and psychiatric disorders can be treated with haloperidol.

A Provide emotional and psychologic support. Rationale: The patient's son will first need emotional and psychologic support. He should be taught about diagnostic genetic testing but should decide for himself with a genetic counselor if and when he wants this done. The treatment plan for his father will be determined based on his father's needs.

In addition to urine function, the nurse recognizes that the kidneys perform numerous other functions important to maintaining homeostasis. Which physiologic processes are performed by the kidneys? (Select all that apply.) A Release of renin B Activation of vitamin D C Carbohydrate metabolism D Erythropoietin production E Hemolysis of old red blood cells (RBCs)

A Release of renin B Activation of vitamin D E Erythropoietin production Rationale: In addition to urine formation, the kidneys release renin to maintain blood pressure, activate vitamin D to maintain calcium levels, and produce erythropoietin to stimulate RBC production. Carbohydrate metabolism and hemolysis of old RBCs are not physiologic functions that are performed by the kidneys.

The nurse is caring for a patient after a right kidney biopsy. How would the nurse position the patient immediately after the procedure? A Right lateral side-lying position B Reverse Trendelenburg position C Supine with lower extremities elevated D High Fowler's position with arms supported

A Right lateral side-lying position Rationale: After a renal biopsy, a pressure dressing should be applied. The patient should be kept on the affected side for 30 to 60 minutes to apply additional pressure from the patient's own body weight and then on bed rest for 24 hours. High Fowler's position with arms supported is a position for a patient in respiratory distress. Reverse Trendelenburg position is used to maintain circulation to the legs in peripheral artery insufficiency. Supine with legs elevated puts excessive pressure on the diaphragm and should generally be avoided.

What are the urine studies for CKD?

A UA can detect RBC's WBC, protein, casts and glucose-persistent proteinuria is usually the first sign of kidney damage.

Which nursing intervention is a priority for a patient with multiple sclerosis (MS)? A Vigilant infection control and adherence to standard precautions B Careful monitoring of neurologic assessment and frequent reorientation C Maintenance of a calorie count and hourly assessment of intake and output D Assessment of blood pressure and monitoring for signs of orthostatic hypotension

A Vigilant infection control and adherence to standard precautions Rationale: Infection control is a priority in the care of patients with MS because infection is the most common cause of an exacerbation of the disease. Decreases in cognitive function are less likely, and MS does not typically result in malnutrition, hypotension, or fluid volume excess or deficit.

What is chronic pyelonephritis?

A continuous infection of the kidneys which leads to inflammation and fibrosis. There may be a loss of renal function and atrophy can occur.

The rapid response team is called to the cafeteria. They find a 22-year-old with a known seizure disorder having a tonic-clonic seizure. What actions will be taken during the seizure? (select all that apply) A establish IV access B insert an oral airway C gently hold the arms to prevent injury D adminster the patient's intranasal midazolam E turn the person on to their side and pad their head

A establish IV access D adminster the patient's intranasal midazolam E turn the person on to their side and pad their head Rationale: This patient has an established seizure disorder. Establish IV access. If they have midazolam nasal spray or midazolam autoinjector, this should be given. Nothing should be put in the patient's mouth during a seizure. No part of the body should be restrained. The patient should be turned on their side and their head protected from injury on the hard floor.

What are some of the medications for RLS?

Requip Dopamine Antiseizure medications Benzodiazepines Opioids

Which points must the nurse consider when planning nutrition support for patients with chronic kidney disease (select all that apply)? A sodium may be restricted B fluid is not usually restricted for patients on peritoneal dialysis C decrease fluid intake and a low potassium diet are needed for a patient on hemodialysis D decreased fluid intake and low potassium diet are needed for peritoneal dialysis E decreased fluid intake and a diet rich in protein-rich foods are part of a diet for a patient

A sodium may be restricted B fluid is not usually restricted for patients on peritoneal dialysis C decrease fluid intake and a low potassium diet are needed for a patient on hemodialysis Rationale: Water and any other fluids are not routinely restricted before Stage 5 end-stage renal disease (ESRD). Patients receiving hemodialysis have a more restricted diet than do patients receiving peritoneal dialysis. Patients receiving hemodialysis are taught about the need for a dietary restriction of potassium- and phosphate-rich foods. Patients receiving peritoneal dialysis may actually need potassium replacement because of the higher losses of potassium with peritoneal dialysis. Sodium and salt restriction is common for all patients with CKD. For those receiving hemodialysis, as their urinary output decreased, fluid restrictions are enhanced. Intake depends on the daily urine output. In general, 600 mL (from insensible loss) plus an amount equal to the previous day's urine output is allowed f

What are the seven functions of the kidneys (think a wet bed)

A-Acid base balance control W-Water balance E-Electrolyte balance T-Toxin & other waste product removal B-Blood pressure control E-Erythropoietin production D-activation of vitamin D

Repetitive without periods of consciousness, more than 3 per hour. Is a serious neurologic emergency, and may be life-threatening. This may lead to - Hypoxia, trauma, hyperthermia, hypoglycemia, aspiration, and dehydration. Most often occur with children and older adults. The brain uses more energy than the body can supply, as neurons become exhausted they cease to function and brain damage can result.

What is an embolic stroke?

Which statement about continuous ambulatory peritoneal dialysis (CAPD) would be most important when teaching a patient new to the treatment? A "Maintain a daily written record of blood pressure and weight." B "It is essential that you maintain aseptic technique to prevent peritonitis." C "You will be allowed a more liberal protein diet once you complete CAPD." D "Continue regular medical and nursing follow-up visits while performing CAPD."

B "It is essential that you maintain aseptic technique to prevent peritonitis." Rationale: Peritonitis is a potentially fatal complication of peritoneal dialysis, and thus it is imperative to teach the patient methods of prevention. Although the other teaching statements are accurate, they do not have the potential for morbidity and mortality that peritonitis does.

The home care nurse visits a patient receiving peritoneal dialysis. Which statement by the patient indicates a need for immediate follow-up by the nurse? A "Drain time is faster if I rub my abdomen." B "The fluid draining from the catheter is cloudy." C "The drainage is bloody when I have my period." D "I wash around the catheter with soap and water."

B "The fluid draining from the catheter is cloudy." Rationale: The primary manifestation of peritonitis is a cloudy peritoneal effluent. Blood may be present in the effluent of women who are menstruating, and no intervention is indicated. Daily catheter care may include washing around the catheter with soap and water. Drain time may be facilitated by gently massaging the abdomen.

The nurse teaches a 28-yr-old female patient who has migraine headaches about sumatriptan (Imitrex). Which statement by the patient requires clarification by the nurse? A "The injection might feel like a bee sting." B "This medicine will prevent a migraine headache." C "I can take another dose if the first does not work." D "This drug for migraine headaches could cause birth defects."

B "This medicine will prevent a migraine headache." Rationale: Sumatriptan is given to abort an ongoing migraine headache and is not used to prevent migraine headaches. When given as a subcutaneous injection, this drug may cause transient pain and redness at the injection site. This drug may be repeated after a specified time period if the first dose is not effective. This drug should be avoided during pregnancy and is classified as a Food and Drug Administration Pregnancy Risk Category C drug.

Which patient has the most significant risk factors for chronic kidney disease (CKD)? A A 50-yr-old white woman with hypertension B A 61-yr-old Native American man with diabetes C A 28-yr-old black woman with a urinary tract infection D A 40-yr-old Hispanic woman with cardiovascular disease

B A 61-yr-old Native American man with diabetes Rationale: The nurse identifies the 61-year-old Native American with diabetes as the most at risk. Diabetes causes about 50% of CKD. This patient is the oldest, and Native Americans with diabetes develop CKD 6 times more frequently than other ethnic groups. Hypertension causes about 25% of CKD. Hispanics have CKD about 1.5 times more than non-Hispanics. Blacks have the highest rate of CKD because hypertension is significantly increased in blacks. A UTI will not cause CKD unless it is not treated or UTIs occur recurrently.

A patient with end-stage renal disease (ESRD) secondary to diabetes has arrived at the outpatient dialysis unit for hemodialysis. Which assessments would the nurse perform as a priority before, during, and after the treatment? A Level of consciousness B Blood pressure and fluid balance C Temperature, heart rate, and blood pressure D Assessment for signs and symptoms of infection

B Blood pressure and fluid balance Rationale: Although all the assessments are relevant to the care of a patient receiving hemodialysis, fluid removal during the procedure will require monitoring blood pressure and fluid balance prior, during, and after.

The nurse observes a patient with Parkinson's disease rocking side to side while sitting in the chair. Which action by the nurse is most appropriate? A Provide the patient with diversional activities. B Document the activity in the patient's health record. C Take the patient's blood pressure sitting and standing. D Ask if the patient is feeling either anxious or depressed.

B Document the activity in the patient's health record. Rationale: Patients with Parkinson's disease are taught to rock from side to side to stimulate balance mechanisms and decrease akinesia.

A patient with type 2 diabetes and chronic kidney disease has a serum potassium level of 6.8 mEq/L. Which finding will the nurse monitor for? A Fatigue B Dysrhythmias C Hypoglycemia D Elevated triglycerides

B Dysrhythmias Rationale: Hyperkalemia is the most serious electrolyte disorder associated with kidney disease. Fatal dysrhythmias can occur when the serum potassium level reaches 7 to 8 mEq/L. Fatigue and hypertriglyceridemia may be present but do not require urgent intervention. Hypoglycemia is a complication related to diabetes control, not hyperkalemia. However, administration of insulin and dextrose is an emergency treatment for hyperkalemia.

A patient has sought care because of recent problems establishing and maintaining a urine stream and occasional pain with urination. How would the nurse document this finding? A Anuria B Dysuria C Oliguria D Enuresis

B Dysuria Rationale: Painful and difficult urination is characterized as dysuria. Whereas anuria is an absence of urine production, oliguria is diminished urine production. Enuresis is involuntary nocturnal urination.

During the oliguric phase of AKI the nurse monitors the patient for (select all that apply) A Hypotension B ECG changes C hypernatremia D pulmonary edema E urine with specific gravity

B ECG changes D pulmonary edema Rationale: The nurse monitors the patient in the oliguric phase of acute renal injury for the following: • Hypertension and pulmonary edema: When urinary output decreases, fluid retention occurs. The severity of the symptoms depends on the extent of the fluid overload. In the case of reduced urine output (i.e., anuria, oliguria), the neck veins may become distended with a bounding pulse. Edema and hypertension may develop. Fluid overload can eventually lead to HF, pulmonary edema, and pericardial and pleural effusions. • Hyponatremia: Damaged tubules cannot conserve sodium. Consequently, the urinary excretion of sodium may increase, which results in normal or below-normal serum levels of sodium. • Electrocardiographic changes and hyperkalemia: Initially, signs of hyperkalemia are apparent on electrocardiogram (ECG), including peaked T waves and a widening of the QRS complex. • Urinary specific gravity: Urinary specific gravity is fixed at about

A patient donated a kidney via a laparoscopic donor nephrectomy to a nonrelated recipient. The patient is having significant pain and refuses to get up to walk. How would the nurse respond? A Allow the patient to rest and try again tomorrow. B Encourage a short walk around the patient's room. C Have the transplant psychologist convince her to walk. D Tell the patient she is lucky she did not have an open nephrectomy.

B Encourage a short walk around the patient's room. Rationale: Because ambulating will improve bowel, lung, and kidney function with improved circulation, even a short walk with assistance should be encouraged after pain medication. The transplant psychologist or social worker's role is to determine if the patient is emotionally stable enough to handle donating a kidney; postoperative care is the nurse's role. Telling the patient she is lucky she did not have an open nephrectomy (implying how much more pain she would be having if it had been open) will not be beneficial to the patient or her postoperative recovery. Early ambulation should be encouraged, waiting until tomorrow is too long.

Diffusion, osmosis, and ultrafiltration occur in both hemodialysis and peritoneal dialysis. Which strategy is used to achieve ultrafiltration in peritoneal dialysis? A Increasing the pressure gradient B Increasing osmolality of the dialysate C Decreasing the glucose in the dialysate D Decreasing the concentration of the dialysate

B Increasing osmolality of the dialysate Rationale: Ultrafiltration in peritoneal dialysis is achieved by increasing the osmolality of the dialysate with additional glucose. In hemodialysis, the increased pressure gradient from increased pressure in the blood compartment or decreased pressure in the dialysate compartment causes ultrafiltration. Decreasing the concentration of the dialysate in either peritoneal or hemodialysis will decrease the amount of fluid removed from the blood stream.

A patient reports a throbbing headache with aura and photophobia. Which diagnosis would the nurse suspect? A Cluster headache B Migraine headache C Polycythemia vera D Hemorrhagic stroke

B Migraine headache Rationale: Although a headache may occur with any of these options, a migraine headache is the only one that has a throbbing headache with an aura (the photophobia). Headache from polycythemia vera is from erythrocytosis. The cluster headache pain is sharp and stabbing. The headache associated with a hemorrhagic stroke has a sudden onset and is not recurrent.

The nurse is caring for a patient with amyotrophic lateral sclerosis (ALS). What strategy would prevent a common cause of death for patients with ALS? A Reduce fat intake. B Reduce the risk of aspiration. C Decrease injury related to falls. D Decrease pain secondary to muscle weakness.

B Reduce the risk of aspiration. Rationale: Reducing the risk of aspiration can help prevent respiratory infections that are a common cause of death from deteriorating muscle function. Reducing fat intake may reduce cardiovascular disease, but this is not a common cause of death for patients with ALS. Decreasing injury related to falls and decreasing pain secondary to muscle weakness are important nursing interventions for patients with ALS but are unrelated to causes of death for these patients.

The nurse is caring for a patient who is in the oliguric phase of acute kidney disease. Which action would be appropriate to include in the plan of care? A Provide foods high in potassium. B Restrict fluids based on urine output. C Monitor output from peritoneal dialysis. D Offer high-protein snacks between meals.

B Restrict fluids based on urine output. Rationale: Fluid intake is monitored during the oliguric phase. Fluid intake is determined by adding all losses for the previous 24 hours plus 600 mL. Potassium and protein intake may be limited in the oliguric phase to avoid hyperkalemia and elevated urea nitrogen. Hemodialysis, not peritoneal dialysis, is indicated in acute kidney injury if dialysis is needed.

A nurse is caring for a patient with chronic obstructive pulmonary disease (COPD) admitted for pneumonia. What laboratory findings would be consistent with decreased kidney function? A Serum uric acid of 5.2 mg/dL B Serum creatinine 2.3 of mg/dL C Urine specific gravity of 1.040 D Blood urea nitrogen (BUN) of 10 mg/dL

B Serum creatinine 2.3 of mg/dL Rationale: An expected assessment finding related to decreased kidney function in the aging process is an increased serum creatinine. Other expected assessments include an elevated BUN and inability to concentrate urine (with urine specific gravity fixed at 1.010). Uric acid is used as a screening test for disorders of purine metabolism or kidney disease; values depend on renal function, rate of purine metabolism, and dietary intake of food rich in purines. Normal reference intervals: serum creatinine, 0.6 to 1.3 mg/dL; BUN, 6 to 20 mg/dL; urine specific gravity, 1.003 to 1.030; and serum uric acid, 2.3 to 6.6 mg/dL (female) or 4.4 to 7.6 mg/dL (male).

The nurse is performing an assessment for a patient and preparing to palpate the kidneys. How would the nurse position the patient for this assessment? A Prone B Supine C Seated at the edge of the bed D Standing, facing away from the nurse

B Supine Rationale: To palpate the right kidney, the patient is positioned supine, and the nurse's left hand is placed behind and supports the patient's right side between the rib cage and the iliac crest. The right flank is elevated with the left hand, and the right hand is used to palpate deeply for the right kidney. The normal-sized left kidney is rarely palpable because the spleen lies directly on top of it.

A patient with multiple sclerosis receives natalizumab every 6 months and modafinil and dalfampridine daily what assessment findings would indicate that the treatment plan was successful? Select all that apply: A blurred vision B improved walking C Decreased fatigue D no change in spacisitity E reduced exacerbation frequency

B improved walking C Decreased fatigue E reduced exacerbation frequency Rationale: Multiple Sclerosis patients have difficulty with vision, continence, constipation, spasticity, walking, fatigue, lack of concentration, and lack of coordination. MS has exacerbations and remissions leading to worse symptoms with each exacerbation. Natalizumab decreases the frequency and severity of exacerbations. Modafinil reduces fatigue, and dalfampridine enhances walking. Establishing a treatment plan with goals related to the reduction of these symptoms and reduction of exacerbations will increase the quality of life for a MS patient.

What is tubular secretion?

passage of a substance from the capillaries through the tubular cells into the lumen of the tubule

Which patient has the highest risk for having a stroke? a. An obese 45-year old Native American. b. A 65-yr-old black man with hypertension. c. A 35-yr-old Asian American women who smokes. d. A 32-yr-old white women taking oral contraceptives.

B. A 65-yr-old black man with hypertension. Rationale: Nonmodifiable risk factors for stroke include age (older than 65 years), male gender, and ethnicity (incidence is highest in Blacks; next highest in Hispanics, Native Americans/Alaska Natives, and Asian Americans; and next highest in white people). Modifiable risk factors for stroke include hypertension (most important), heart disease (especially atrial fibrillation), smoking, abdominal obesity, metabolic syndrome, and lack of physical exercise.

What is pneumaturia?

passage of urine containing gas (a fistula connections between bowel and bladder-gas forming UTI)

A patient with kidney disease has oliguria and a creatinine clearance of 40 mL/min. These findings most directly reflect abnormal function of a. tubular secretion b. glomerular filtration c. capillary permeability d. concentration of filtrate

B. glomerular filtration Rationale: The amount of blood filtered each minute by the glomeruli is expressed as the glomerular filtration rate (GFR). The normal GFR is about 125 mL/min.

Bladder training in a male patient who has urinary incontinence after a stroke includes a. limiting fluid intake. b. helping the patient to stand to void. c. keeping a urinal in place at all times. d. catheterizing the patient every 4 hours.

B. helping the patient to stand to void. Rationale: In the acute stage of stroke, the primary urinary problem is poor bladder control and incontinence. A bladder retraining program consists of (1) adequate fluid intake, with the greatest fluid intake between 7:00 AM and 7:00 PM; and (2) scheduled toileting every 2 hours with the use of a urinal, commode, or bathroom, (3) assisting with clothing and mobility; and (4) encouraging the usual position for urinating.

For a patient who is suspected of having a stroke, the most important piece of information that the nurse can obtain is a. time of the patient's last meal. b. time at which stroke symptoms first appeared. c. patient's hypertension history and management. d. family history of stroke and other cardiovascular diseases.

B. time at which stroke symptoms first appeared. Rationale: During initial evaluation, the most crucial point in the patient's history is the time since onset of stroke symptoms. If the stroke is ischemic, recombinant tissue plasminogen activator (tPA) must be given within 3 to 4½ hours of the onset of signs of ischemic stroke; tPA reestablishes blood flow through a blocked artery and prevents brain cell death in patients with acute onset of ischemic stroke.

What is BEFAST?

B: BALANCE: SUDDEN LOSS OF BALANCE E: EYES: LOSS OF VISION IN ONE OR BOTH EYES F: FACE: FACE looks uneven, droopy, and numbness A: ARM: ARM/LEG WEAK/HANGING DOWN S: SPEECH: SPEECH SLURRED OR TROUBLE SPEAKING/SEEMS CONFUSED T: TIME: Time is critical, CALL 911 NOW!

Discuss Diazepam (Diastat, Intensol, Valium) Nursing implications/patient education:

Black box warning related to the concomitant use of opioids. Contraindicated with any other respiratory depressants and in children less than 6 months old. Avoid the use of diazepam more than five episodes per month or one episode every five days. Women should be cautioned against getting pregnant or breast feeding during the use of this medication (previously a category Dper the US food and drug administration).

What are post renal kidney problems?

Bladder or prostate problems ~BPH (Benign Prostatic Hyperplasia) ~Calculi formation ~Bladder or prostate cancer ~Strictures ~Trauma (back, pelvis, perineum)

What are the manifestations of a lower urinary tract infection?

Bladder storage, bladder emptying. Symptoms include dysuria, frequency, urgency, suprapubic discomfort or pressure, may present with blood in the urine.

What is intracerebral hemorrhage?

Bleeding within the brain caused by rupture of vessel. Usually in the basal ganglia. The prognosis is poor. Hypertension is the most common cause. Manifestations include neurologic defects, headache, nausea, vomiting, decreased LOC, and hypertension.

Other aphasias

Result from damage to different language areas in the brain, some may have trouble repeating words and sentences even though they can understand the meaning of the word or sentence. May have trouble naming objects even though they know what the object is and what its use is.

The nurse prepares a patient for discharge after a cystoscopy. It is most important for the nurse to provide additional information in response to which patient statement? A "I should drink plenty of fluids to prevent complications." B "If my urine is cloudy, I should contact my health care provider." C "Bright red bleeding is normal for a few days after the procedure." D "Sitz baths and acetaminophen will help to reduce my discomfort."

C "Bright red bleeding is normal for a few days after the procedure." Rationale: Bright red bleeding after a cystoscopy is not normal and should be reported immediately. Other complications include urinary retention, bladder infection, and perforation of the bladder. Patients should drink plenty of fluids and expect burning on urination, pink-tinged urine, and urinary frequency. Warm sitz baths, heat, and mild analgesics may be used to relieve discomfort.

The nurse provides diet teaching to the in-home caregiver of a patient with Huntington's disease. The nurse would be most concerned if the caregiver makes which statement? A "Depression is common and may cause a decrease in appetite." B "If swallowing becomes difficult, a feeding tube may be needed." C "Calories should be restricted to prevent unnecessary weight gain." D "Muscles in the face are affected, and chewing may become impossible."

C "Calories should be restricted to prevent unnecessary weight gain." Patients with Huntington's disease may require 4000 to 5000 calories/day to maintain body weight. Weight loss occurs in patients with Huntington's disease because of choreic movements, difficulty swallowing, depression, and mental deterioration.

A patient tells the nurse that they have burning on urination, dysuria, and frequency. What is the best response by the nurse? A "Drink less fluid so you don't have to void so often." B "Take some acetaminophen to decrease the discomfort." C "Come in so we can check a clean-catch urine specimen." D "Avoid caffeine and spicy food to decrease inflammation."

C "Come in so we can check a clean-catch urine specimen." Rationale: The patient's symptoms are typical of a urinary tract infection. To verify this, a clean-catch urine specimen must be obtained for a specimen of urine to culture. Drinking less fluid will not improve the symptoms. Acetaminophen would not decrease the discomfort; an antibiotic would be needed. Avoiding caffeine and spicy food may decrease bladder inflammation but will not affect these symptoms.

The nurse provides information to the caregiver of a patient with epilepsy who has tonic-clonic seizures. Which statement by the caregiver indicates a need for further teaching? A "The jerking movements may last for 30 to 40 seconds." B "It is normal for a person to be sleepy after a seizure." C "I should call 911 if breathing slows during the seizure." D "Objects should not be placed in the mouth during a seizure."

C "I should call 911 if breathing slows during the seizure." Rationale: Caregivers do not need to call an ambulance or send a person to the hospital after a single seizure unless the seizure is prolonged, another seizure immediately follows, or extensive injury has occurred. Altered breathing is a manifestation of a tonic-clonic seizure. Contact emergency medical services (or call 911) if breathing stops for more than 30 seconds. No objects (e.g., oral airway, padded tongue blade) should be placed in the mouth. Lethargy is common in the postictal phase of a seizure. Jerking of the extremities occurs during the clonic phase of a tonic-clonic seizure. The clonic phase may last 30 to 40 seconds.

The nurse is caring for a group of patients on a medical unit. After receiving report, which patient would the nurse see first? A A 42-yr-old patient with multiple sclerosis who was admitted with sepsis B A 72-yr-old patient with Parkinson's disease who has aspiration pneumonia C A 38-yr-old patient with myasthenia gravis who declined prescribed medications D A 45-yr-old patient with amyotrophic lateral sclerosis who refuses enteral feedings

C A 38-yr-old patient with myasthenia gravis who declined prescribed medications. Rationale: Patients with myasthenia gravis who discontinue pyridostigmine (Mestinon) will develop myasthenic crisis. Myasthenia crisis results in severe muscle weakness and can lead to a respiratory arrest.

Which patient problem is the priority when caring for a patient with myasthenia gravis (MG)? A Acute confusion B Bowel incontinence C Activity intolerance D Disturbed sleep pattern

C Activity intolerance Rationale: The primary feature of MG is fluctuating weakness of skeletal muscle. Bowel incontinence and confusion are unlikely signs of MG. Although sleep disturbance is likely, activity intolerance is of primary concern.

When establishing a diagnosis of multiple sclerosis (MS), which diagnostic tests would the nurse expect? (Select all that apply.) A EEG B ECG C CT scan D Carotid duplex scan E Evoked response testing F Cerebrospinal fluid analysis

C CT scan E Evoked response testing F Cerebrospinal fluid analysis Rationale: No definitive diagnostic test exists for MS. Along with history and physical examination, CT scan, evoked response testing, cerebrospinal fluid analysis, and MRI are used to establish a diagnosis of MS. EEG, ECG, and carotid duplex scan are not used to diagnose MS.

The provider has decided to use renal replacement therapy to remove large volumes of fluid from a patient who is hemodynamically unstable in the intensive care unit (ICU). The nurse would expect which treatment to be used? A Hemodialysis (HD) three times per week B Automated peritoneal dialysis (APD) C Continuous venovenous hemofiltration (CVVH) D Continuous ambulatory peritoneal dialysis (CAPD)

C Continuous venovenous hemofiltration (CVVH) Rationale: CVVH removes large volumes of water and solutes from the patient over a longer period of time by using ultrafiltration and convection. HD three times per week would not be used for this patient because fluid and solutes build up and then are rapidly removed. With APD (used at night instead of during the day) fluid and solutes build up during the day and would not benefit this patient as much. CAPD will not as rapidly remove large amounts of fluid as CVVH can do.

During hemodialysis, the patient develops light-headedness and nausea. What would the nurse do first? A Give hypertonic saline. B Initiate a blood transfusion. C Decrease the rate of fluid removal. D Administer antiemetic medications.

C Decrease the rate of fluid removal. Rationale: The patient is having hypotension from a rapid removal of vascular volume. The rate and volume of fluid removal will be decreased, and 0.9% saline solution may be infused. Hypertonic saline is not used because of the high sodium load. A blood transfusion is not indicated. Antiemetic medications may help the nausea but would not help the hypovolemia.

The nurse is caring for an older adult patient taking bumetanide. What age-related changes does the nurse teach the patient they may experience? A Benign enlargement of prostatic tissues B Decreased sensation of bladder capacity C Decreased function of the loop of Henle D Less absorption in the Bowman's capsule

C Decreased function of the loop of Henle Rationale: Bumetanide (Bumex) is a loop diuretic that acts in the loop of Henle to decrease reabsorption of sodium and chloride. Because the loop of Henle loses function with aging, the excretion of drugs becomes less and less efficient. Thus, the circulating levels of drugs are increased and their effects prolonged. Benign prostatic tissue enlargement, decreased bladder sensation, and loss of concentrating ability do not directly affect the action of loop diuretics.

A patient is recovering in the intensive care unit (ICU) 24 hours after receiving a kidney transplant. What is an expected assessment finding during the earliest stage of recovery? Hypokalemia Hyponatremia Large urine output Leukocytosis with cloudy urine output

C Large urine output Rationale: Patients often have diuresis in the hours and days immediately after a kidney transplant. Electrolyte imbalances and signs of infection are unexpected findings that warrant prompt intervention.

Which characteristic would the nurse associate with a focal seizure? A The patient lost consciousness during the seizure. B The seizure involved both sides of the patient's brain. C The seizure involved lip smacking and repetitive movements. D The patient fell to the ground and became stiff for 20 seconds.

C The seizure involved lip smacking and repetitive movements. Rationale: Complex focal seizure is often characterized by lip smacking and automatisms (repetitive movements that may not be appropriate). Loss of consciousness, bilateral brain involvement, and a tonic phase are associated with generalized seizure activity.

The nurse conducts a home visit with a patient with Parkinson's disease taking levodopa/carbidopa daily. The patient has stopped eating meals with his family and has lost 3 pounds since the last visit a week ago. What action would the nurse take? A. plan 6 small high protein meals per day B. Provide information on a high fat ketogenic diet C evaluate their ability to eat, swallow and use of assistive devices. D. Collaborate with the HCP about every other day levodopa/carbidopa dosing.

C evaluate their ability to eat, swallow and use of assistive devices. Rationale: Patients with Parkinson's disorder have trouble with the coordinated act of eating, often require assistive devices to eat, and have difficulty swallowing. Diet is of major concern as malnutrition can occur without adequate calories and nutrient intake. The uncoordinated movements and tremors and slow eating can be embarrassing for the patient who may be isolating from the family. The nurse must determine if physical difficulty with the act of eating is causing the weight loss or if depression or another organic cause is to blame. Identifying the root of the problem would start with assessing the patient's abilities. Ketogenic diets are for headaches. Protein makes levodopa less effective, so protein should be limited to the evening meal. Reducing levodopa/carbidopa dosing will increase the tremors and bradykinesia.

When the patient is in the diuretic phase of AKI the nurse must monitor for serum electrolyte imbalances? A hyperkalemia and hyponatremia B hyperkalemia and hypernatremia C hypokalemia and hyponatremia D hypokalemia and hypernatremia

C hypokalemia and hyponatremia Rationale: In the diuretic phase of AKI, the kidneys have recovered the ability to excrete wastes but not the ability to concentrate urine. Hypovolemia and hypotension can result from massive fluid losses. Because of the large losses of fluid and electrolytes, monitor the patient for hyponatremia, hypokalemia, and dehydration.

What does the upper urinary system consist of?

Two kidneys and two ureters

A patient in the urgent care reports a stabbing headache around his left eye and nasal stuffiness. He says "this pain is horrible, it is worse than my heart attack last year." The provider orders sumatriptan nasal spray now for headache relief. The nurse would take what action? A. Administer a puff to each nostril now. B. Take vital signs prior to administration. C. Contact the provider about administering the medication to this patient. D. Teach the patient to self-administer the medication at

C. Contact the provider about administering the medication to this patient. Rationale The patient is experiencing a cluster headache. While triptans are appropriate for relieving an ongoing headache, sumatriptan causes vasoconstriction and is contraindicated for patients with an MI. The provider should be notified of this patient's history. Sumatriptan inhaler is given as one puff in one nare only. Verapamil would be used for the prevention of cluster headaches, sumatriptan is not prescribed to prevent cluster headaches. The nurse should take vital signs, but this patient should not take the medication, so the first action would be to verify the correct order.

The nurse explains to the patient with a stroke who is scheduled for angiography that this test is used to determine the a. presence of increased ICP. b. site and size of the infarction. c. patency of the cerebral blood vessels. d. presence of blood in the cerebrospinal fluid.

C. patency of the cerebral blood vessels. Rationale: Angiography provides visualization of cerebral blood vessels and can help estimate perfusion and detect filling defects in the cerebral arteries.

A patient having TIAs is scheduled for a carotid endarterectomy. The nurse explains that this procedure is done to a. decrease cerebral edema. b. reduce the brain damage that occurs during a stroke in evolution. c. prevent a stroke by removing atherosclerotic plaques blocking cerebral blood flow. d. provide a circulatory bypass around thrombotic plaques obstructing cranial circulation.

C. prevent a stroke by removing atherosclerotic plaques blocking cerebral blood flow. Rationale: In a carotid endarterectomy, the atheromatous lesion is removed from the carotid artery to improve blood flow.

What are the impacts of hypertension?

COronary artery disease, left ventricular hypertrophy, and heart failure. Brain-major risk for stroke Peripheral vasculature-speeds up atherosclerotic processes Kidney-renal disease, and kidney malfunction Eyes-retinal damage

What are the studies that confirm the diagnosis of stroke?

CT scan CT angiography (CTA) CT/MRI perfusion and diffusion imaging MRI Magnetic resonance angiography (MRA)

What are some Metabolic manifestations that accompany CKD?

Carbohydrate intolerance Hyperlipidemia

What cardiac assessments are required for stroke?

Cardiac markers (troponin, creatine kinase-MB) Chest X-ray Echocardiography (transthoracic, transesophageal) ECG

What factors manitain adequate blood flow to the brain?

Cardiac output, vasomotor tone, distribution to blood flow. Cardiac output must be reduced by one third before cerebral blood flow is reduced.

What the most common causes of death in a patient with CKD

Cardiovascular disease MI, heart failure, cardiomyopathy, stroke CVD and CKD are closely linked HTN is a cause and consequence of CKD

What are the studies that determine cerebral blood flow?

Carotid angiography Carotid duplex scanning Cerebral angiography Digital subtraction angiography Transcranial doppler ultrasonography

Discuss temporary vascular access for dialysis:

Catheter insertion of internal jugular or femoral vein when immediate access is needed. Double lumen-blood removal, blood return Risks:high infection, dislodgement, and malfunction.

What additional studies may help with stroke diagnosis and involvement?

Coagulation studies (prothrombin time, activated partial thromboplastin time) CBC with platelets Electrolyte panel with blood glucose Lipid profile Renal and hepatic studies.

What is the function of the tubules?

Collecting ducts that are responsible for the reabsorption of essential materials and excretion of the nonessentials. These functions are carried out by reabsorption and secretion.

What is the difference between complicated and uncomplicated UTI?

Complicated UTI"S occur in a patient with underlying disease with a structural or functional problem in the urinary tract. Uncomplicated UTI's occur in an otherwise normal urinary tract.

What are the urethras primary functions?

Control voiding Serve a a conduit for urine from the bladder to the outside of the body during voiding.

What is the best serum indicator for acute kidney injury?

Creatinine is not affected by other factors.

The bladder, urethra, and pelvic floor muscles form what?

Urethrovesical unit

What are the blood studies for CKD?

GFR-best indicator BUN-affected by diet, tissue breakdown, medications Creatinine-more sensitive than BUN-good indicator Elevate triglycerides- hyperinsulinemia stimulates hepatic production of triglycerides. Anemia-scant production of erythropoietin Metabolic acidosis-unable to excrete acid, unable to reabsorb sodium bicarbonate

A frail elderly patient with stage 3 chronic kidney disease is cared for at home by their family. The patient has a history of taking many over-the-counter medications. Which over-the-counter medications would the nurse teach the patient to avoid? A Aspirin B Acetaminophen C Diphenhydramine D Aluminum hydroxide

D Aluminum hydroxide Rationale: Antacids (that contain magnesium and aluminum) should be avoided because patients with kidney disease are unable to excrete these substances. Also, some antacids contain high levels of sodium that further increase blood pressure. Acetaminophen and aspirin (if taken for a short period of time) are usually safe for patients with kidney disease. Antihistamines may be used, but combination drugs that contain pseudoephedrine may increase blood pressure and should be avoided.

A patient with a 25-year history of type 1 diabetes is reporting fatigue, edema, and an irregular heartbeat. On assessment, the nurse notes newly developed hypertension and uncontrolled blood glucose levels. Which diagnostic study is most indicative of chronic kidney disease (CKD)? A Serum creatinine B Serum potassium C Microalbuminuria D Calculated glomerular filtration rate (GFR)

D Calculated glomerular filtration rate (GFR) Rationale: The best study to determine kidney function or CKD that would be expected in the patient with diabetes is the calculated GFR that is obtained from the patient's age, gender, race, and serum creatinine. It would need to be abnormal for 3 months to establish a diagnosis of CKD. A creatinine clearance test done with a blood sample and a 24-hour urine collection is also important. Serum creatinine is not the best test for CKD because the level varies with different patients. Serum potassium levels could explain why the patient has an irregular heartbeat. The finding of microalbuminuria can alert the patient with diabetes about potential renal involvement and potentially failing kidneys. However, urine albumin levels are not used for diagnosis of CKD.

Which patient diagnosis or treatment is most consistent with prerenal acute kidney injury (AKI)? A IV tobramycin B Incompatible blood transfusion C Poststreptococcal glomerulonephritis D Dissecting abdominal aortic aneurysm

D Dissecting abdominal aortic aneurysm Rationale: A dissecting abdominal aortic aneurysm is a prerenal cause of AKI because it can decrease renal artery perfusion and therefore the glomerular filtrate rate. Aminoglycoside antibiotic administration, a hemolytic blood transfusion reaction, and poststreptococcal glomerulonephritis are intrarenal causes of AKI.

A patient in the intensive care unit is receiving gentamicin for treatment of pneumonia from Pseudomonas aeruginosa. What assessment finding would the nurse report to the health care provider? A Decreased weight B Increased appetite C Increased urinary output D Elevated creatinine level

D Elevated creatinine level Rationale: Gentamicin can be toxic to the kidneys and the auditory system. The elevated creatinine level must be reported to the provider because it probably indicates renal damage. Other factors that may occur with renal damage would include increased weight and decreased urinary output. Many medications have side effects of anorexia.

A 28-year-old patient who's mother has Huntington disease is discussing family planning with the nurse. The patient says that they want to have a child but are concerned. What statement will the nurse make? A both parents must have the gene for your child to inherit this disease B if you have the Huntington mutation, you will not be able to have children. C only about 1 in 10 people who have the gene will pass it on to their children. D Genetic testing can be done to determine if you can pass th

D Genetic testing can be done to determine if you can pass this trait on to a child. Rationale: This patient is younger than the age when Huntington's disease manifests symptoms. Concern about passing the disorder can cause families to question their reproductive choices. The mutation is autosomal dominant and only 1 parent needs to carry it. 50% of their children can have the mutation. If they have the mutation, they will get the disorder. Since the patient has not shown symptoms and may not for many more years, they can be tested to see if they have the mutation and can pass it to any future children.

The nurse preparing to give a dose of calcium acetate to a patient with chronic kidney disease (CKD). Which laboratory result will the nurse monitor to determine if the desired effect was achieved? A Sodium B Potassium C Magnesium D Phosphorus

D Phosphorus Rationale: Phosphorus and calcium have inverse or reciprocal relationships, meaning that when phosphorus levels are high, calcium levels tend to be low. Therefore, administration of calcium should help to reduce a patient's abnormally high phosphorus level, as seen with CKD. Calcium acetate will not have an effect on sodium, potassium, or magnesium levels.

A patient with a diagnosis of Parkinson's disease (PD) is admitted to a long-term care facility. Which action would the health care team take to promote adequate nutrition? A Administer multivitamins every morning and with each meal. B Provide a diet that is low in complex carbohydrates and high in protein. C Give the patient with a pureed diet that is high in potassium and low in sodium. D Provide small, frequent meals throughout the day that are easy to chew and swallow.

D Provide small, frequent meals throughout the day that are easy to chew and swallow. Rationale: Nutrition support is a priority in the care of persons with PD. Patients may benefit from smaller, more frequent meals that are easy to chew and swallow. Multivitamins are not necessary at each meal. Vitamin and protein intake must be monitored to prevent interactions with medications. Introducing a minced or pureed diet is likely premature, and a low carbohydrate diet is not indicated.

When caring for a patient during the oliguric phase of acute kidney injury (AKI), which nursing action is appropriate? A Weigh patient three times weekly. B Increase dietary sodium and potassium. C Provide a low-protein, high-carbohydrate diet. D Restrict fluids according to previous daily loss.

D Restrict fluids according to previous daily loss. Rationale: Patients in the oliguric phase of AKI will have fluid volume excess with potassium and sodium retention. Therefore, they will need to have dietary sodium, potassium, and fluids restricted. Daily fluid intake is based on the previous 24-hour fluid loss (measured output plus 600 mL for insensible loss). The diet also needs to provide adequate, not low, protein intake to prevent catabolism. The patient should also be weighed daily, not just three times each week.

A patient reports acute, severe, renal colic pain in the lower abdomen. The nurse suspects that an obstruction is most likely at which area? A Kidney B Urethra C Bladder D Ureterovesical junction

D Ureterovesical junction Rationale: The ureterovesical junction is the narrowest part of the urethra and easily obstructed by urinary calculi. With a stone in the kidney or at the ureteropelvic junction, the pain may be dull costovertebral flank pain. Stones in the bladder do not cause obstruction or symptoms unless they are staghorn stones. The urethra seldom has obstruction related to stones.

The nurse obtained a urine specimen from a patient. What result would the nurse recognize as abnormal? A pH of 6.0 B Amber yellow color C Specific gravity of 1.025 D White blood cells (WBCs) 9/hpf

D White blood cells (WBCs) 9/hpf Rationale: Normal WBC levels in urine are below 5/hpf, with levels exceeding this indicative of inflammation or urinary tract infection. A urine pH of 6.0 is average; amber yellow is normal coloration, and the reference range for specific gravity is 1.003 to 1.030.

A renal stone in the pelvis of the kidney will alter the function of the kidney by interfering with the a. structural support of the kidney b. regulation of the concentration of urine c. entry and exit of blood vessels at the kidney d. collection and drainage of urine from the kidney

D collection and drainage of urine from the kidney Rationale: the outer layer of the kidney is the cortex, and the inner layer is the medulla. The medulla consists of a number of pyramids. The apices (tops) of these pyramids are called papillae, through which urine passes to enter the calyces. The minor calyces widen and merge to form major calyces, which form a funnel-shaped sac called the renal pelvis. The minor and major calyces transport urine to the renal pelvis, from which it drains through the ureter to the bladder.

The nurse using RIFLE to determine the early stage of AKI evaluates the patients: A blood pressure and urine osmolality B fractional excretion of urinary sodium C estimation of GFR with MDRD equation D serum creatinine or urine output from baseline

D serum creatinine or urine output from baseline Rationale: The RIFLE classification describes the stages of AKI. RIFLE standardizes the diagnosis of AKI. Risk (R) is the first stage of AKI, followed by injury (I), which is the second stage, and then increasing in severity to the last or third stage of failure (F). The 2 outcome variables are loss (L) and end-stage renal disease (E). The first 3 stages are characterized by the serum creatinine level and urine output.

Information provided by the patient that would help distinguish a hemorrhagic stroke from a thrombotic stroke includes a. sensory changes. b. a history of hypertension. c. presence of motor weakness. d. sudden onset of severe headache.

a. progressive irreversible destruction of the kidneys Rationale: Chronic kidney disease (CKD) involves progressive, irreversible loss of kidney function. A focus on stages 1 through 4 before the need for dialysis (stage 5) includes the control of hypertension, hyper parathyroid disease, CKD-MBD, anemia, and dyslipidemia.

An ESRD patient receiving hemodialysis is considering asking a relative to donate a kidney for transplantation. In assisting the patient to make a decision about treatment, the nurse informs the patient that a. successful transplantation usually provides better quality of life than that offered by dialysis b. if rejection of the transplant occurs, no further treatment for the renal failure is available c. hemodialysis replaces the normal functions of the kidneys, and patients do not have to live

a. successful transplantation usually provides better quality of life than that offered by dialysis Rationale: Kidney transplantation is extremely successful, with 1-year graft survival rates of about 90% for deceased donor organs and 95% for live donor organs. An advantage of kidney transplantation over dialysis is that it reverses many of the pathophysiologic changes associated with renal failure when normal kidney function is restored. It also eliminates the dependence on dialysis and the need for the accompanying dietary and lifestyle restrictions. Transplantation is less expensive than dialysis after the first year.

A diagnostic study that evaluates renal blood flow, glomerular filtration, tubular function, and excretion is a(n) a- IVP b- VCUG c- renal scan d- loopagram

c- renal scan Rationale: A renal scan evaluates the anatomic structures, perfusion, and function of kidneys. The scan shows the location, size, and shape of the kidneys and helps assess blood flow, glomerular filtration, tubular function, and urinary excretion. In some facilities, a numerical value ("split" renal function) may be assigned (i.e., percent contributed by each kidney).

What happens in the proximal convoluted tubule?

reabsorption of water, ions, and all organic nutrients

to assess the patency of a newly place AV graft for dialysis, the nurse should (SATA) a. monitor the BP in the affected arm b. irrigate the graft daily with low-dose heparin c. palpate the area of the graft to feel a normal thrill d. listen with a stethoscope over the graft to detect a bruit e. frequently monitor the pulses and neurovascular status distal to the graft

c. palpate the area of the graft to feel a normal thrill d. listen with a stethoscope over the graft to detect a bruit e. frequently monitor the pulses and neurovascular status distal to the graft Rationale: A thrill can be felt on palpation of the area of anastomosis of the arteriovenous graft, and a bruit can be heard with a stethoscope. The bruit and thrill are created by arterial blood rushing into the vein. The BP should not be taken in the arm with the AV graft.

~Convulsive status epilepticus-most common form, with prolonged or repeated tonic-clonic or other motor seizures. ~Non-convulsive status epilepticus-repeated focal impaired awareness seizures. ~Refractory status epilepticus-continuous seizure activity despite administration of first and second-line therapy-high risk for mortality and neurologic damage. ~Super refractory-continuous or recurs 24 hours or more after starting anesthesia treatment. ~Subclinical seizures-a form of status epilepticus in which a sedated patient seizes but no external signs because of sedative use. Most often from tonic clinic seizures. Common at night.

What is care relate to AKI?

~Managing fluid volumes determine the adequate intravascular volume and cardiac output for perfusion to kidneys diuretics may be given-furosemide/lasix, bumetanide/bumex, osmotic diuretics/Mannitol fluid restriction (add up losses from day before) ~Hyperkalemia (most serious) Insulin and sodium bicarb are used to promote the transient shift of potassium to cells, dietary restriction of potassium and hemodialysis, oral suspension that binds potassium in GI tract patiromer/altessa ~Nutritional therapy sodium & potassium limited based on plasma levels, sodium-edema, HTN and heart failure. Carbs and fat to prevent ketosis from fat breakdown and glucogenesis. High protein may be bad.

How is epilepsy diagnosed?

~Medical History ~Tests: CBC, serum electrolytes, serum Ca++, ,liver and kidney function, urinalysis, drug levels, skull & chest x-ray to look for abnormalities, lumbar puncture, brain studies (CT and MRI), electroencephalography ~Imaging (EEG) to look at the electrical activity of the brain and abnormalities (should be done within 24 hours of suspected seizure) ~Clinical Observation: motor function, sensory function, neuropsychological eval ~Notes: accurate descriptions and video recordings help diagnose & classify types of seizures, CT, MRI, MRA, MRS, PET scan.
