E. coli organisms responsible for hemolytic uremic syndrome have been recovered from all of the following EXCEPT

Correct Answer: A

Rationale: In pediatric genitourinary nursing, understanding the sources of E. coli organisms related to hemolytic uremic syndrome is crucial for effective intervention. The correct answer, A) fomites, is the right choice because E. coli responsible for hemolytic uremic syndrome is primarily transmitted through contaminated food and water sources, not through inanimate objects like fomites. Option B) meat is incorrect because E. coli can be present in undercooked meat, especially ground beef. Option C) apple cider is incorrect as E. coli outbreaks have been linked to unpasteurized apple cider. Option D) swimming pools is also incorrect as E. coli can survive in water contaminated with feces. Educationally, this question highlights the importance of understanding the sources of E. coli infections in pediatric patients. Nurses need to be vigilant in educating families about food safety, proper meat preparation, avoiding unpasteurized beverages, and practicing good hygiene to prevent the transmission of E. coli and subsequent hemolytic uremic syndrome. Understanding these sources can help nurses provide targeted interventions and education to prevent infections in pediatric patients.

Correct Answer: C

Rationale: In neonates with bilateral renal agenesis, death is primarily due to pulmonary insufficiency (Option C). This condition, known as Potter syndrome, results in oligohydramnios during pregnancy, leading to underdeveloped lungs (pulmonary hypoplasia). Without functional kidneys to produce amniotic fluid, the fetus's lungs do not develop properly, causing respiratory distress and ultimately fatal pulmonary insufficiency after birth. Option A, renal failure, is incorrect because the absence of functional kidneys means renal failure does not occur as the kidneys are absent. Hypertension (Option B) is not the primary cause of death in this scenario, although it can be a complication of renal failure in other conditions. Congenital heart disease (Option D) is not directly linked to bilateral renal agenesis but may coexist in some cases due to developmental abnormalities. Understanding the pathophysiology of conditions like bilateral renal agenesis is crucial for pediatric genitourinary nurses to provide appropriate care and interventions for neonates at risk. Recognizing the primary cause of mortality in these cases helps nurses prioritize respiratory support and palliative care to improve outcomes for these vulnerable patients.

Correct Answer: D

Rationale: In the context of pediatric genitourinary nursing interventions, understanding the symptoms of cystitis is crucial for accurate assessment and timely intervention. The correct answer, option D) suprapubic pain, is indicative of cystitis in pediatric patients. Cystitis, or inflammation of the bladder, commonly presents with symptoms such as suprapubic pain due to irritation of the bladder lining. This symptom is specific to genitourinary issues and is a key indicator for diagnosing cystitis. Option A) fever is not typically a primary symptom of cystitis in pediatric patients. While some children may develop a low-grade fever as a response to infection, it is not a defining characteristic of cystitis. Option B) polyuria, or increased urination, is a more common symptom of conditions such as diabetes or urinary tract infection, rather than cystitis specifically. While polyuria can occur in some cases of cystitis, it is not a consistent or defining symptom for this condition. Option C) nausea is a nonspecific symptom that can occur in various illnesses and conditions. While some children with cystitis may experience nausea, it is not a primary symptom associated with this condition. Educationally, understanding the specific symptoms of cystitis in pediatric patients helps nurses and healthcare providers differentiate it from other genitourinary issues. By recognizing key symptoms like suprapubic pain, healthcare professionals can provide timely and appropriate interventions to manage and treat cystitis effectively in pediatric patients.

Correct Answer: C

Rationale: In this question about vesicoureteral reflux (VUR) in pediatric genitourinary nursing interventions, the correct answer is C) the mean age at VUR resolution is 10 years. Explanation: - The correct answer is that the mean age at VUR resolution is 10 years because VUR often resolves spontaneously as children grow older due to maturation of the urinary tract anatomy and function. - Option A is true because VUR is typically a congenital condition, meaning it is present at birth. - Option B is also true as severe cases of VUR can lead to kidney damage and hypertension in children if left untreated. - Option D is true as the severity of VUR is commonly graded using voiding cystourethrogram, a radiographic imaging study. Educational Context: Understanding VUR is crucial for pediatric nurses as it is a common urinary issue in children. Knowing that VUR often resolves by the age of 10 helps nurses in their patient care and management strategies. Nurses need to be aware of the potential complications of VUR, such as kidney damage and hypertension, to provide timely interventions and prevent long-term consequences. Grasping the diagnostic methods like voiding cystourethrogram aids nurses in collaborating with healthcare providers to determine appropriate treatment plans for children with VUR.

Correct Answer: D

Rationale: In pediatric genitourinary nursing, understanding when prompt surgical repair is indicated in ureteropelvic junction obstruction is crucial for providing optimal care to infants. The correct answer, D) hematuria after minimal trauma, is not an indication for prompt surgical repair in this context. Hematuria after minimal trauma is more suggestive of a renal parenchymal injury rather than ureteropelvic junction obstruction. Surgical repair in ureteropelvic junction obstruction is typically indicated in cases where there is a risk of renal damage or functional impairment. Option A) solitary kidney is a high-risk factor that may necessitate prompt intervention to preserve renal function. Option B) abdominal mass could indicate a secondary complication requiring intervention. Option C) bilateral severe hydronephrosis indicates significant obstruction and potential renal damage if not addressed promptly. Educationally, understanding the nuances of when surgical intervention is indicated in pediatric genitourinary conditions helps nurses make critical clinical decisions that impact patient outcomes. Recognizing the different clinical presentations and indications for intervention ensures appropriate and timely care for infants with ureteropelvic junction obstruction.
