A nurse is caring for a client in the emergency department with a diagnosis of renal calculi. Which of the following areas of the renal system do most renal calculi begin forming?
Bladder
Renal papilla
Ureter
Urethra
The Correct Answer is B
Choice A reason: The bladder is not where renal calculi typically begin to form; it is where they may end up if they travel down from the kidneys.
Choice B reason: Renal calculi commonly begin forming at the renal papilla, which is part of the kidney where urine collects before it flows into the ureter.
Choice C reason: The ureter is not the typical starting point for the formation of renal calculi, though stones can travel through it.
Choice D reason: The urethra is not a common site for the formation of renal calculi; it is the duct through which urine is discharged.

Explanation
Choice A reason: A WBC count can help determine the presence of infection.
Choice B reason: Blood cultures may be ordered if there is a concern for a systemic infection or sepsis.
Choice C reason: Foley catheter placement is not typically indicated for UTI and can increase the risk of infection.
Choice D reason: A broad-spectrum antibiotic may be prescribed to treat the suspected UTI until specific causative bacteria are identified.
Choice E reason: IV fluids may be administered to ensure hydration, especially if the client is unable to maintain adequate oral intake due to nausea or vomiting.
Choice F reason: A clean-catch urinalysis and urine culture are essential to identify the specific bacteria causing the UTI and to determine the appropriate antibiotic therapy.
Correct Answer is ["50"]
Explanation
Step 1: The total amount of phenytoin required per dose is 250 mg.
Step 2: Each 5 mL of oral solution contains 25 mg of phenytoin.
Step 3: To find out how many mL are needed, we divide the total amount required by the amount in each 5 mL of oral solution. So, (250 mg ÷ 25 mg/5 mL).
Step 4: The result is 50 mL.
So, the nurse should administer 50 mL per dose. This is already a whole number, so no rounding is necessary.
