Question 7
Regular
What recommendation should the nurse make to prevent urinary tract infections (UTIs) in young girls?
Correct!
Incorrect
The correct answer is: D
Rationale
Ensure clear liquid intake of 2 L/day.
Adequate hydration helps dilute urine and flush out bacteria from the urinary tract, significantly reducing the risk of urinary tract infections in young girls. This practice promotes urinary health and prevents the growth of harmful microorganisms, making it an essential preventive measure.
A: Avoid public toilet facilities. Avoiding public restrooms does not directly address the underlying factors contributing to UTIs and may not be practical for young girls in various situations.
B: Limit long baths as much as possible. While excessive bathing may irritate the genital area, it does not directly contribute to the prevention of UTIs in young girls.
C: Cleanse the perineum with water after voiding. Although cleansing is important for hygiene, it alone does not provide sufficient protection against UTIs without adequate hydration to flush the urinary system.

Question 8
Regular
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?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Have siblings examined for VUR. It is crucial to assess siblings for vesicoureteral reflux because VUR can be hereditary. Identifying potential cases early allows for timely intervention and management of the condition to prevent complications.
A: Limit fluids to reduce reflux. Reducing fluid intake could lead to dehydration and is not an effective strategy for managing VUR, which requires a comprehensive treatment approach rather than fluid restriction.
B: Give cranberry juice twice a day. While cranberry juice may support urinary health, it does not address the underlying causes of VUR or pyelonephritis, making this advice insufficient for effective management.
D: Surgery is indicated to reverse scarring. Surgical intervention is not always necessary for VUR; many cases can be managed conservatively. Surgery typically is considered only after other treatment options have been exhausted.

Question 9
Regular
What pathologic process is believed to be responsible for the development of postinfectious glomerulonephritis?
Correct!
Incorrect
The correct answer is: B
Rationale
Immune complex formation and glomerular deposition is believed to be responsible for the development of postinfectious glomerulonephritis. This condition arises when immune complexes, formed in response to infection, accumulate in the glomeruli, leading to inflammation and impaired renal function.
A: Infarction of renal vessels does not align with postinfectious glomerulonephritis, as this condition primarily involves inflammation due to immune responses rather than blood vessel blockages within the kidneys.
C: Bacterial endotoxin deposition on and destruction of glomeruli does not accurately describe the underlying mechanism, as the primary pathology is related to immune complex deposition rather than direct bacterial damage to glomerular structures.
D: Embolization of glomeruli by bacteria and fibrin from endocardial vegetation does not represent the primary cause of postinfectious glomerulonephritis, which focuses more on immune response rather than direct embolic events affecting glomerular health.

Question 10
Regular
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?
Correct!
Incorrect
The correct answer is: B
Rationale
Weight loss in this child is most likely due to a reduction of edema. In acute glomerulonephritis, fluid retention can cause significant weight gain, and as treatment progresses, excess fluid is lost, leading to weight loss.
A: Poor appetite A lack of appetite may contribute to weight loss, but it is unlikely to account for the significant weight change observed in this case.
C: Restriction to bed rest Bed rest may limit physical activity, yet it does not inherently lead to weight loss unless accompanied by other factors like decreased intake or fluid loss.
D: Increased potassium intake A rise in potassium intake does not directly result in weight loss and may not significantly affect the child's fluid balance or overall weight during hospitalization.

Question 11
Regular
What measure of fluid balance status is most useful in a child with acute glomerulonephritis?
Correct!
Incorrect
The correct answer is: B
Rationale
Daily weight is the most useful measure of fluid balance status in a child with acute glomerulonephritis.
Monitoring daily weight allows for precise assessment of fluid retention or loss, which is crucial in managing the condition. Changes in weight reflect shifts in body fluid status, enabling timely interventions to prevent complications such as edema and hypertension associated with glomerulonephritis.
A: Proteinuria. While proteinuria indicates kidney damage, it does not provide direct information on fluid balance or retention in the body.
C: Specific gravity. This measure reflects urine concentration but does not offer comprehensive insights into overall fluid status or retention in children with glomerulonephritis.
D: Intake and output. Although tracking intake and output is beneficial, it may not accurately reflect fluid shifts and retention as effectively as daily weight monitoring does.

Question 12
Regular
The parent of a child hospitalized with acute glomerulonephritis asks the nurse why blood pressure readings are being taken so often. What knowledge should influence the nurses reply?
Correct!
Incorrect
The correct answer is: C
Rationale
Acute hypertension is a concern that requires monitoring. Continuous blood pressure assessment is vital in acute glomerulonephritis to identify potential complications, including increased fluid retention and kidney dysfunction, which can lead to severe health risks.
A: The antibiotic therapy contributes to labile blood pressure values. While medications may affect blood pressure, they are not the primary reason for frequent monitoring in this condition.
B: Hypotension leading to sudden shock can develop at any time. Although hypotension is a concern, the primary focus in acute glomerulonephritis is the risk of hypertension rather than hypotensive episodes.
D: Blood pressure fluctuations indicate that the condition has become chronic. Acute glomerulonephritis is characterized by sudden onset symptoms, and fluctuations do not signify a chronic state but rather the acute nature of the disease.

What laboratory finding, in conjunction with the presenting symptoms, indicates minimal change nephrotic syndrome?
Correct!
Incorrect
The correct answer is: D
Rationale
Reduced serum albumin indicates minimal change nephrotic syndrome. This finding aligns with the hallmark of nephrotic syndrome, which is characterized by significant proteinuria leading to hypoalbuminemia, fluid retention, and other symptoms.
A: Low specific gravity. While low specific gravity can suggest concentration issues, it does not specifically indicate minimal change nephrotic syndrome, as it can arise from various renal conditions.
B: Decreased hemoglobin. Decreased hemoglobin suggests anemia, which is not a defining feature of minimal change nephrotic syndrome, and does not correlate directly with the protein loss characteristic of this condition.
C: Normal platelet count. A normal platelet count does not provide evidence for minimal change nephrotic syndrome; rather, it indicates that hematological status remains stable, which is not directly relevant to nephrotic syndrome diagnosis.
