A nurse is preparing a client for a kidney biopsy. Which of the following client conditions should the nurse identify as a contraindication for this diagnostic test?
Elevated creatinine level
Urinary retention
Flank pain
Bleeding tendencies
The Correct Answer is D
Choice A reason: An elevated creatinine level indicates reduced kidney function, which is often the reason a kidney biopsy is being performed in the first place. It is not a contraindication for the procedure.
Choice B reason: Urinary retention does not directly impact the ability to perform a kidney biopsy, as the procedure involves the kidneys and not the lower urinary tract where urine is stored.
Choice C reason: Flank pain is a common symptom in patients with kidney issues and is not a contraindication for a kidney biopsy. The procedure may help diagnose the cause of the ?ank pain.
Choice D reason: Bleeding tendencies are a significant contraindication for a kidney biopsy. Patients with a history of bleeding disorders or those on anticoagulant therapy are at increased risk of bleeding complications from the procedure.

Correct Answer is B
Explanation
Choice A reason: The pH of urine can vary, but having a more alkalotic urine does not necessarily promote the growth of bacteria. Urine is typically slightly acidic, which helps to prevent bacterial growth.
Choice B reason: The primary anatomical reason for the higher rates of UTIs in clients who have vaginas is the shorter length of the urethra compared to those who do not have vaginas. This shorter distance makes it easier for bacteria from the skin or rectal area to enter the bladder.
Choice C reason: The strength of the detrusor muscle, which controls the emptying of the bladder, does not have a direct correlation with the frequency of UTIs. UTIs are more related to bacterial invasion rather than muscle strength.
Choice D reason: Bladder capacity is generally not a factor in the frequency of UTIs. While residual urine can increase the risk of UTIs, this is not typically related to overall bladder capacity.
Correct Answer is A
Explanation
Choice A reason: In acute kidney injury (AKI), the blood urea nitrogen (BUN) level is expected to be elevated due to the kidneys' impaired ability to excrete urea, which is a waste product of protein metabolism. Normal BUN levels range from approximately 7 to 20 mg/dL.
Choice B reason: Hypercalcemia is not commonly associated with AKI. Instead, patients with AKI may experience hypocalcemia due to the kidneys' reduced ability to convert vitamin D to its active form, which is necessary for calcium absorption.
Choice C reason: Metabolic alkalosis is not a typical finding in AKI. More commonly, patients with AKI experience metabolic acidosis because the kidneys are unable to excrete acid effectively, leading to an accumulation of acid in the body.
Choice D reason: Hypokalemia is generally not expected in AKI. The condition is more often associated with hyperkalemia, as the impaired kidney function leads to a reduced excretion of potassium, which can accumulate to dangerous levels.
