Chapter 53 : Assessment of Kidney and Urinary Function Questions
Question 1 of 5
A nurse is aware of the high incidence and prevalence of fluid volume deficit among older adults. What related health education should the nurse provide to an older adult?
Correct Answer: C
Rationale: The nurse emphasizes the need to drink throughout the day even if the patient does not feel thirsty, because the thirst stimulation is decreased. Four liters of daily fluid intake is excessive and fluids other than water are acceptable in most cases. Additional salt intake is not recommended as a prompt for increased fluid intake.
Question 2 of 5
A patient is scheduled for a diagnostic MRI of the lower urinary system. What pre-procedure education should the nurse include?
Correct Answer: B
Rationale: Patient preparation should include teaching relaxation techniques because the patient needs to remain still during an MRI. The patient does not normally need to be NPO or fluid-restricted before the test and conscious sedation is not usually implemented.
Question 3 of 5
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?
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.
Question 4 of 5
A patient is scheduled for diagnostic testing to address prolonged signs and symptoms of genitourinary dysfunction. What signs and symptoms are particularly suggestive of urinary tract disease? Select all that apply.
Correct Answer: B,C,D
Rationale: Dysfunction of the kidney can produce a complex array of symptoms throughout the body. Pain, changes in voiding, and gastrointestinal symptoms are particularly suggestive of urinary tract disease. Jaundice and petechiae are not associated with genitourinary health problems.
Question 5 of 5
A patient asks the nurse why kidney problems can cause gastrointestinal disturbances. What relationship should the nurse describe?
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.
