A patient asks the nurse why kidney problems can cause gastrointestinal disturbances. What relationship should the nurse describe?
- A. The right kidneys proximity to the pancreas, liver, and gallbladder
- B. The indirect impact of digestive enzymes on renal function
- C. That the peritoneum encapsulates the GI system and the kidneys
- D. The left kidneys connection to the common bile duct
Correct Answer: A
Rationale: The proximity of the right kidney to the colon, duodenum, head of the pancreas, common bile duct, liver, and gallbladder may cause GI disturbances. The proximity of the left kidney to the colon (splenic flexure), stomach, pancreas, and spleen may also result in intestinal symptoms. Digestive enzymes do not affect renal function and the left kidney is not connected to the common bile duct.

A nurse is preparing a patient diagnosed with benign prostatic hypertrophy (BPH) for a lower urinary tract cystoscopic examination. The nurse informs the patient that the most common temporary complication experienced after this procedure is what?
- A. Urinary retention
- B. Bladder perforation
- C. Hemorrhage
- D. Nausea
Correct Answer: A
Rationale: After a cystoscopic examination, the patient with obstructive pathology may experience urine retention if the instruments used during the examination caused edema. The nurse will carefully monitor the patient with prostatic hyperplasia for urine retention. Post-procedure, the patient will experience some hematuria, but is not at great risk for hemorrhage. Unless the condition is associated with another disorder, nausea is not commonly associated with this diagnostic study. Bladder perforation is rare.
The nurse is caring for a patient who describes changes in his voiding patterns. The patient states, I feel the urge to empty my bladder several times an hour and when the urge hits me I have to get to the restroom quickly. But when I empty my bladder, there doesnt seem to be a great deal of urine flow. What would the nurse expect this patients physical assessment to reveal?
- A. Hematuria
- B. Urine retention
- C. Dehydration
- D. Renal failure
Correct Answer: B
Rationale: Increased urinary urgency and frequency coupled with decreasing urine volumes strongly suggest urine retention. Hematuria may be an accompanying symptom, but is likely related to a urinary tract infection secondary to the retention of urine. Dehydration and renal failure both result in a decrease in urine output, but the patient with these conditions does not have normal urine production and decreased or minimal flow of urine to the bladder. The symptoms of urgency and frequency do not accompany renal failure and dehydration due to decreased urine production.
Results of a patients 24 -hour urine sample indicate osmolality of510 \mathrm{mOsm} / \mathrm{kg}$, which is within reference range. What conclusion can the nurse draw from this assessment finding?
- A. The patients kidneys are capable of maintaining acidbase balance.
- B. The patients kidneys reabsorb most of the potassium that the patient ingests.
- C. The patients kidneys can produce sufficiently concentrated urine.
- D. The patients kidneys are producing sufficient erythropoietin.
Correct Answer: C
Rationale: Osmolality is the most accurate measurement of the kidneys ability to dilute and concentrate urine. Osmolality is not a direct indicator of renal function as it relates to erythropoietin synthesis or maintenance of acidbase balance. It does not indicate the maintenance of healthy levels of potassium, the vast majority of which is excreted.
The nurse is reviewing the electronic health record of a patient with a history of incontinence. The nurse reads that the physician assessed the patients deep tendon reflexes. What condition of the urinary/renal system does this assessment address?
- A. Renal calculi
- B. Bladder dysfunction
- C. Benign prostatic hyperplasia (BPH)
- D. Recurrent urinary tract infections (UTIs)
Correct Answer: B
Rationale: The deep tendon reflexes of the knee are examined for quality and symmetry. This is an important part of a testing for neurologic causes of bladder dysfunction, because the sacral area, which innervates the lower extremities, is in the same peripheral nerve area responsible for urinary continence. Neurologic function does not directly influence the course of renal calculi, BPH or UTIs.
The nurse is caring for a patient suspected of having renal dysfunction. When reviewing laboratory results for this patient, the nurse interprets the presence of which substances in the urine as most suggestive of pathology?
- A. Potassium and sodium
- B. Bicarbonate and urea
- C. Glucose and protein
- D. Creatinine and chloride
Correct Answer: C
Rationale: The various substances normally filtered by the glomerulus, reabsorbed by the tubules, and excreted in the urine include sodium, chloride, bicarbonate, potassium, glucose, urea, creatinine, and uric acid. Within the tubule, some of these substances are selectively reabsorbed into the blood. Glucose is completely reabsorbed in the tubule and normally does not appear in the urine. However, glucose is found in the urine if the amount of glucose in the blood and glomerular filtrate exceeds the amount that the tubules are able to reabsorb. Protein molecules are also generally not found in the urine because amino acids are also filtered at the level of the glomerulus and reabsorbed so that it is not excreted in the urine.
