What recommendation should the nurse make to prevent urinary tract infections (UTIs) in young girls?
- A. Avoid public toilet facilities.
- B. Limit long baths as much as possible.
- C. Cleanse the perineum with water after voiding.
- D. Ensure clear liquid intake of 2 L/day.
Correct Answer: D
Rationale: Adequate fluid intake (e.g., 2 L/day for a 5-6-year-old) minimizes urinary stasis, reducing UTI risk. Public toilets and long baths aren?t directly linked to UTIs, and perineal cleansing with water lacks evidence as a primary preventive measure.

The nurse notes that a child has lost 3.6 kg (8 lb) after 4 days of hospitalization for acute glomerulonephritis. What is the most likely cause of this weight loss?
- A. Poor appetite
- B. Reduction of edema
- C. Restriction to bed rest
- D. Increased potassium intake
Correct Answer: B
Rationale: Rapid weight loss of 8 lb in 4 days in acute glomerulonephritis is due to improved renal function and mobilization of edema fluid. Poor appetite and bed rest don?t cause such significant loss, and potassium is restricted, not increased, until renal function normalizes.
What pathologic process is believed to be responsible for the development of postinfectious glomerulonephritis?
- A. Infarction of renal vessels
- B. Immune complex formation and glomerular deposition
- C. Bacterial endotoxin deposition on and destruction of glomeruli
- D. Embolization of glomeruli by bacteria and fibrin from endocardial vegetation
Correct Answer: B
Rationale: Postinfectious glomerulonephritis results from immune complexes formed after streptococcal infection, depositing in glomerular capillaries. Renal vessel infarction occurs in sickle cell disease, bacterial endotoxins aren?t involved, and embolization is linked to bacterial endocarditis.
The nurse is teaching a client to prevent future urinary tract infections (UTIs). What factor is most important to emphasize as the potential cause?
- A. Poor hygiene
- B. Constipation
- C. Urinary stasis
- D. Congenital anomalies
Correct Answer: C
Rationale: Urinary stasis is the primary host factor promoting UTIs by providing a bacterial growth medium. Poor hygiene and constipation contribute by facilitating bacterial entry or causing stasis via rectal pressure, but stasis is the key driver. Congenital anomalies are less common causes.
What is the primary objective of care for the child with minimal change nephrotic syndrome (MCNS)?
- A. Reduce blood pressure.
- B. Lower serum protein levels.
- C. Minimize excretion of urinary protein.
- D. Increase the ability of tissue to retain fluid.
Correct Answer: C
Rationale: The primary goal in MCNS is to minimize urinary protein excretion, reducing edema and complications. Blood pressure is typically normal, serum protein levels need to increase, and fluid retention (edema) is a problem to be reduced, not increased.
In teaching the parent of a newly diagnosed 2-year-old child with pyelonephritis related to vesicoureteral reflux (VUR), the nurse should include which information?
- A. Limit fluids to reduce reflux.
- B. Give cranberry juice twice a day.
- C. Have siblings examined for VUR.
- D. Surgery is indicated to reverse scarring.
Correct Answer: C
Rationale: VUR has a 36% incidence in siblings, necessitating screening to detect and prevent scarring. Fluid restriction is not advised, cranberry juice lacks proven efficacy in children, and surgery may be needed for severe VUR but doesn?t reverse existing scarring.
