A 6-year-old boy presents with fever, flank pain, and hematuria. Urinalysis shows pyuria and bacteria. The most likely diagnosis is

Correct Answer: B

Rationale: In this case, the most likely diagnosis for the 6-year-old boy presenting with fever, flank pain, hematuria, pyuria, and bacteria in the urine is acute pyelonephritis (Option B). The correct answer is B) acute pyelonephritis because the symptoms described are classic signs of a kidney infection rather than just a bladder infection (acute cystitis - Option A). Acute pyelonephritis involves inflammation of the renal parenchyma and collecting system, leading to more systemic symptoms and severe complications compared to cystitis. Option C) ureteropelvic junction obstruction and Option D) hydronephrosis are structural abnormalities that can cause urinary symptoms but are less likely in this scenario given the acute onset of symptoms and presence of infection markers in the urine. Educationally, understanding the distinction between acute cystitis and acute pyelonephritis is crucial for pediatric genitourinary nursing interventions. It is important to recognize the signs and symptoms of pyelonephritis early to prevent complications such as sepsis and renal scarring in children. This knowledge helps in prompt diagnosis, appropriate treatment with antibiotics, and preventing long-term sequelae in pediatric patients.

Correct Answer: B

Rationale: In pediatric genitourinary nursing, understanding anomalies like hypospadias is crucial. The correct answer is B) on the ventral surface of the penis. Hypospadias is characterized by the urethral meatus opening on the ventral aspect of the penis instead of at the tip of the glans penis, which is the normal anatomical location. Option A) on the dorsum of the penis is incorrect as hypospadias involves the ventral surface. Option C) at the tip of the glans penis is also incorrect as this is the normal location of the urethral meatus. Option D) at the base of the scrotum is incorrect as this location is not associated with hypospadias. Educationally, understanding the anatomical variations in conditions like hypospadias is essential for nurses caring for pediatric patients. Recognizing these anomalies helps in providing appropriate nursing interventions and postoperative care for surgical correction. Nurses play a vital role in educating families about these conditions and supporting them throughout the treatment process.

Correct Answer: B

Rationale: In the management of suspected Wilm's tumor in pediatrics, the correct initial approach is option B) chemotherapy followed by surgery. This is based on evidence-based guidelines that recommend preoperative chemotherapy to shrink the tumor, decrease the risk of intraoperative tumor rupture, and improve overall surgical outcomes. Surgery is then performed to remove the remaining tumor and affected kidney, if necessary. Option A) immediate surgical resection is not the preferred initial management because it can increase the risk of intraoperative complications due to the size of the tumor. Biopsy, as in option C), is also not recommended initially as it can lead to tumor seeding and upstaging. Option D) observation with serial imaging is not appropriate as Wilm's tumor is an aggressive malignancy that requires prompt intervention. In an educational context, understanding the rationale behind the preferred treatment approach for Wilm's tumor is crucial for pediatric genitourinary nursing interventions. It highlights the importance of a multidisciplinary approach involving oncologists, surgeons, and nurses to provide comprehensive care for pediatric patients with cancer. This knowledge equips healthcare professionals to deliver evidence-based, patient-centered care in pediatric oncology settings.

Correct Answer: A

Rationale: In pediatric genitourinary nursing, understanding the most common causes of end-stage renal disease (ESRD) in children is crucial for providing effective care. The correct answer is A) congenital anomalies of the kidney and urinary tract. This is because congenital anomalies, such as obstructive uropathy or vesicoureteral reflux, can lead to chronic kidney damage over time, ultimately resulting in ESRD. Option B) glomerulonephritis is a common cause of acute kidney injury in children, but it typically does not progress to ESRD in the same way as congenital anomalies do. Option C) hereditary nephritis, while a potential cause of chronic kidney disease, is not as common in children as congenital anomalies. Option D) diabetes mellitus is a leading cause of ESRD in adults but is rare in children. Understanding these distinctions is essential for nurses caring for pediatric patients with genitourinary issues. By recognizing the most common causes of ESRD in children, nurses can implement appropriate interventions, monitor for complications, and educate families on prevention strategies. This knowledge enhances the quality of care provided to pediatric patients with renal conditions.

Correct Answer: B

Rationale: In pediatric kidney transplant recipients, the immunosuppressive regimen typically includes calcineurin inhibitors and steroids (Option B) for several reasons. Calcineurin inhibitors like tacrolimus or cyclosporine are essential in preventing organ rejection by inhibiting T-cell activation. Steroids, such as prednisone, are also crucial as they have broad anti-inflammatory and immunosuppressive effects, further reducing the risk of rejection. Option A, using steroids alone, is not the preferred choice in pediatric kidney transplant recipients because it may not provide adequate immunosuppression to prevent rejection, leading to graft failure. Mycophenolate mofetil (Option C) is commonly used in combination with calcineurin inhibitors and steroids, rather than as a standalone therapy, due to its synergistic immunosuppressive effects. Sirolimus (Option D) is another immunosuppressant, but it is not typically used as the primary agent in pediatric kidney transplant recipients due to concerns about its nephrotoxicity and limited efficacy compared to calcineurin inhibitors. Educationally, understanding the rationale behind the immunosuppressive regimen in pediatric kidney transplant recipients is crucial for pediatric genitourinary nurses. It ensures optimal care for these vulnerable patients, minimizes the risk of rejection, and promotes successful long-term outcomes post-transplantation. By grasping the principles of immunosuppression in this context, nurses can effectively monitor for complications, educate patients and families, and collaborate with the healthcare team to provide comprehensive care.
