Answer
  • Drink at least eight glasses of water a day.
  • Take medication if you have a fever
  • Rest as much as you can in the next few days.
  • After using the bathroom, wipe from front to back.

Question 9

Question
A healthcare professional is assessing a patient who could have either pyelonephritis or cystitis. Which differentiating sign would assist the professional in making this diagnosis?
Answer
  • Difficulty starting the stream of urine
  • Spasmodic pain that radiates to the groin
  • Increased glomerular filtration rate
  • Urinalysis confirmation of white blood cell casts

Question 10

Question
An 85-year-old person has a urinary tract infection. What clinical manifestation does the healthcare professional expect to see in this person?
Answer
  • Confusion and poorly localized abdominal discomfort
  • Dysuria, frequency, and suprapubic pain
  • Hematuria and flank pain
  • Pyuria, urgency, and frequency

Question 11

Question
Pyelonephritis is usually caused by which type of organism?
Answer
  • Bacteria
  • Fungi
  • Viruses
  • Parasites

Question 12

Question
Which abnormal laboratory value is found in glomerular disorders?
Answer
  • Elevated creatinine concentration
  • Low blood urea nitrogen (BUN)
  • Elevated immunoglobulin A (IgA)
  • Low serum complement

Question 13

Question
Which glomerular lesion is characterized by thickening of the glomerular capillary wall with immune deposition of immunoglobulin G (IgG) and C3?
Answer
  • Proliferative
  • Membranous
  • Mesangial
  • Crescentic

Question 14

Question
Goodpasture syndrome is an example of which of these?
Answer
  • Antiglomerular basement membrane disease
  • Acute glomerulonephritis
  • Chronic glomerulonephritis
  • Immunoglobulin A (IgA) nephropathy

Question 15

Question
A patient exhibits symptoms including hematuria with red blood cell casts and proteinuria exceeding 3 to 5 g/day, with albumin as the major protein. What diagnostic test or treatment regime does the healthcare professional educate the patient on?
Answer
  • Intravenous pyelogram
  • Oral antibiotics
  • Renal biopsy
  • Cyclophosphamide

Question 16

Question
Hypothyroidism, edema, hyperlipidemia, and lipiduria characterize which kidney disorder?
Answer
  • Nephrotic syndrome
  • Acute glomerulonephritis
  • Chronic glomerulonephritis
  • Pyelonephritis

Question 17

Question
A patient who has a history of mildly decreased renal function is admitted to the hospital for IV antibiotics. Which antibiotics would the healthcare professional avoid in this patient?
Answer
  • Penicillin and ampicillin
  • Vancomycin and bacitracin
  • Gentamicin and tobramycin
  • Cefazolin and cefepime

Question 18

Question
Which urine characteristics are indicative of acute tubular necrosis (ATN) caused by intrinsic (intrarenal) failure?
Answer
  • Urine sodium >30 mEq/L
  • Urine osmolality >500 mOsm
  • Fractional excretion of sodium (FENa) <1%
  • Urine sediment has no cells, some hyaline casts

Question 19

Question
How are glucose and insulin used to treat hyperkalemia associated with acute renal failure?
Answer
  • Glucose has an osmotic effect, which attracts water and sodium, resulting in more dilute blood and a lower potassium concentration.
  • When insulin transports glucose into the cell, it also carries potassium with it.
  • Potassium attaches to receptors on the cell membrane of glucose and is carried into the cell.
  • Increasing insulin causes ketoacidosis, which causes potassium to move into the cell in exchange for hydrogen.

Question 20

Question
Creatinine is primarily excreted by glomerular filtration after being constantly released from what type of tissue?
Answer
  • Nervous system
  • Kidneys
  • Muscle
  • Liver

Question 21

Question
A professor has taught a student about skeletal alterations seen in chronic kidney disease. Which statement by the student indicates the professor needs to give more information?
Answer
  • Parathyroid hormone is no longer effective in maintaining serum phosphate levels.
  • The parathyroid gland is no longer able to secrete sufficient parathyroid hormone
  • The synthesis of 1,25-vitamin D3, which reduces intestinal absorption of calcium, is impaired.
  • The effectiveness of calcium and phosphate resorption from bone is impaired.

Question 22

Question
A patient who has chronic kidney disease has hemoglobin of 7.2 mg/dL. What treatment does the healthcare professional prepare the patient for?
Answer
  • Intrinsic factor
  • Vitamin B12
  • Vitamin D
  • Erythropoietin

Question 23

Question
When the right kidney is obstructed, how will the glomeruli and tubules in the left kidney compensate?
Answer
  • Increase in number
  • Increase in size
  • Develop collateral circulation
  • Increase speed of production

Answer
  • Neurogenic bladder
  • Obstructed bladder
  • Necrotic bladder
  • Retrograde bladder
