To reduce the risk of serious infections in children with nephrotic syndrome, all the following immunizations can be used EXCEPT

Correct Answer: D

Rationale: In children with nephrotic syndrome, who are at an increased risk of serious infections due to their compromised immune system, it is crucial to provide appropriate immunizations to prevent these infections. The correct answer, D) varicella-zoster vaccine, is not typically recommended for children with nephrotic syndrome due to the live attenuated nature of the vaccine, which poses a risk of causing an infection in immunocompromised individuals. A) Pneumococcal 13-valent conjugate vaccine and C) pneumococcal 23-valent polysaccharide vaccine are important for preventing pneumococcal infections, which are a significant concern in children with nephrotic syndrome. These vaccines help protect against serious conditions like pneumonia and meningitis. B) Influenza vaccine annually is also essential for children with nephrotic syndrome as influenza can lead to severe complications in immunocompromised individuals. Annual vaccination is recommended to provide continuous protection against different strains of the influenza virus. Educationally, this question highlights the importance of understanding immunization recommendations for children with nephrotic syndrome. It emphasizes the need for healthcare providers to be aware of the specific vaccines that are safe and effective for this population to prevent serious infections and complications.

Correct Answer: B

Rationale: The correct answer is B) inhibiting ammonia genesis. In hyperkalemic (Type IV) renal tubular acidosis, there is impaired ammoniagenesis in the proximal tubule leading to decreased NH4+ excretion. This results in decreased buffering capacity in the urine, leading to hyperkalemia and metabolic acidosis. Option A) hyperaldosteronism is incorrect because hyperkalemic (Type IV) RTA is not due to excess aldosterone activity. Option C) pseudohyperaldosteronism is incorrect as well because it does not play a direct role in the pathogenesis of hyperkalemic RTA. Option D) massive bicarbonate wasting is incorrect as this would be more characteristic of a different type of RTA (Type II). Understanding the pathogenesis of hyperkalemic (Type IV) renal tubular acidosis is crucial for nurses and healthcare professionals caring for pediatric patients with renal disorders. By grasping the mechanisms involved, healthcare providers can better manage electrolyte imbalances and acid-base disturbances in these patients. This knowledge is especially important when administering medications or fluids that can impact renal function in pediatric patients.

Correct Answer: A

Rationale: In pediatric pharmacology, understanding genitourinary conditions is crucial for providing safe and effective care to pediatric patients. The most common cause of hydronephrosis in children is ureteropelvic junction obstruction (option A). This condition occurs when there is a blockage at the point where the ureter meets the renal pelvis, leading to the backup of urine and subsequent dilation of the kidney. Vesicoureteral reflux (option B) is a condition where urine flows backward from the bladder into the ureters and potentially the kidneys, but it is not the primary cause of hydronephrosis. Posterior urethral valves (option C) are a rare congenital anomaly that primarily affects male infants and leads to obstruction of the urethra, not the ureteropelvic junction. Ureterocele (option D) is a cystic dilation of the distal ureter, which can cause obstruction but is less common than ureteropelvic junction obstruction in pediatric patients. Educationally, it is important to differentiate between these conditions to ensure accurate diagnosis and appropriate treatment. Understanding the pathophysiology of each condition is essential for pediatric nurses and healthcare providers to provide comprehensive care to pediatric patients with genitourinary issues. By knowing the most common cause of hydronephrosis in children is ureteropelvic junction obstruction, healthcare professionals can promptly recognize and address this condition to prevent complications and promote optimal outcomes for pediatric patients.

Correct Answer: C

Rationale: Testicular torsion is most commonly seen in adolescents (Option C) because this condition often occurs during puberty when the testes undergo significant growth and increased mobility within the scrotum. The rapid growth and development during adolescence can lead to an increased risk of testicular torsion due to the long spermatic cord and the increased potential for twisting. Neonates (Option A) are less likely to experience testicular torsion due to the underdeveloped nature of their reproductive system. Prepubertal boys (Option B) are also at a lower risk compared to adolescents because their testes are not as large and do not have the same degree of mobility. Elderly men (Option D) are unlikely to develop testicular torsion as this condition is more commonly associated with younger age groups. In an educational context, understanding the age groups most at risk for testicular torsion is crucial for healthcare professionals, especially those working with pediatric populations. Recognizing the signs and symptoms of testicular torsion in adolescents can lead to prompt diagnosis and treatment, which is essential to preserving testicular function and preventing complications. This knowledge is not only important for passing exams like the NCLEX but also for providing quality care to patients in clinical practice.

Correct Answer: D

Rationale: In pediatric pharmacology, understanding genitourinary conditions like hydronephrosis is crucial. The correct answer, D) bladder outlet obstruction, is the most common cause of acquired hydronephrosis in children. This obstruction leads to a backup of urine in the kidneys, causing dilation of the renal pelvis and calyces. Option A) ureteropelvic junction obstruction, is a congenital condition usually present at birth and less commonly an acquired cause. Option B) vesicoureteral reflux, involves the abnormal flow of urine from the bladder back up the ureters and is not a direct cause of hydronephrosis. Option C) ureteral stricture, is a narrowing of the ureter and can lead to hydronephrosis but is less common in children. Educationally, it is important to recognize the different etiologies of hydronephrosis in children to provide appropriate care and treatment. Understanding the common causes helps nurses and healthcare providers to assess and manage pediatric patients effectively, ensuring optimal outcomes and quality of care.
