The nurse closely monitors the temperature of a child with minimal change nephrotic syndrome. The purpose of this assessment is to detect an early sign of which possible complication?

Correct Answer: A

Rationale: Monitoring the temperature of a child with minimal change nephrotic syndrome is crucial to detect early signs of infection. Infection is a common complication in nephrotic syndrome, and fever can be an early indicator. Hypertension (choice B) is not typically associated with nephrotic syndrome. Encephalopathy (choice C) is a neurological complication and would present with altered mental status rather than a change in temperature. Edema (choice D) is a common symptom of nephrotic syndrome but is not typically monitored through temperature assessment.

Correct Answer: A

Rationale: Petechiae, infection, and fatigue are common signs and symptoms of leukemia related to bone marrow involvement. Petechiae are small red or purple spots on the skin caused by bleeding under the skin due to low platelet counts. Infection susceptibility increases due to decreased white blood cells from compromised bone marrow function. Fatigue is a common symptom of anemia resulting from decreased red blood cell production. Choices B, C, and D are incorrect as they do not align with the typical signs and symptoms of leukemia associated with bone marrow dysfunction.

Correct Answer: C

Rationale: When palpating the abdomen of an infant with hypertrophic pyloric stenosis (HPS), the nurse would expect to feel an olive-sized mass in the right upper quadrant. This finding is characteristic of HPS due to the hypertrophied pylorus muscle. Choices A, B, and D are incorrect. A distended colon is not typically associated with HPS. Marked tenderness around the umbilicus is not a specific finding of HPS. Rhythmic peristaltic waves in the lower abdomen are not expected in HPS, as the condition primarily affects the pylorus region of the stomach.

Correct Answer: A

Rationale: The correct answer is A: 'Mental retardation occurs if PKU is untreated.' Phenylketonuria (PKU) is a metabolic disorder that results in the inability to metabolize phenylalanine properly. Without proper dietary management, high levels of phenylalanine can lead to severe mental retardation and other neurological problems. Therefore, educating parents about the importance of early and consistent treatment to prevent mental retardation is crucial. Choice B is incorrect because testing for PKU is typically done shortly after birth, not immediately. Choice C is incorrect because treatment for PKU primarily involves strict dietary management to control phenylalanine intake, not lifelong medications. Choice D is incorrect because PKU is inherited in an autosomal recessive pattern, not as an autosomal dominant gene.

Correct Answer: D

Rationale: The correct answer is D: Preventing cardiac overload. Infants are highly vulnerable to fluid overload, making it essential to carefully monitor IV flow rates to prevent complications such as cardiac overload. Rapid administration of IV fluids can lead to an excessive increase in circulating volume, potentially causing cardiac strain or heart failure in infants. Choices A, B, and C are incorrect. Monitoring the IV flow rate is not primarily aimed at limiting output, replacing lost fluids, or avoiding IV infiltration in this scenario. The key concern is to prevent the risk of cardiac overload due to the infant's susceptibility to fluid imbalances.
