In pediatric shock, which of the following is an early sign?

Correct Answer: D

Rationale: In pediatric shock, recognizing early signs is crucial for prompt intervention. The correct answer is D) Tachycardia. Tachycardia is a hallmark sign of shock in children, reflecting the body's compensatory mechanism to maintain perfusion. In shock, the body tries to increase heart rate to improve blood flow and oxygen delivery to vital organs. Option A) Hypotension is a late sign in pediatric shock. Children can maintain blood pressure until shock is advanced, making hypotension a delayed indicator. Option B) Disturbed consciousness level typically occurs in later stages of shock when cerebral perfusion is significantly compromised. Option C) Cheyne-Stokes breathing is a pattern of breathing seen in neurologically impaired patients or those with severe brain injury, not specific to early pediatric shock. Educationally, understanding early signs of pediatric shock is vital for nurses caring for children. Recognizing tachycardia as an early indicator can prompt timely interventions to stabilize the child's condition and prevent progression to severe shock. It highlights the importance of frequent assessments and knowledge of pediatric shock presentation to provide effective care.

Correct Answer: C

Rationale: In pediatric nursing, understanding the correct rate of chest compressions during CPR is crucial for saving infants' lives. The ideal rate of chest compression during CPR in infants is 100 per minute (Option C). This rate is recommended by the American Heart Association (AHA) for effective circulation and oxygenation. Option A (150 per minute) is too fast for infants and may not allow for adequate chest recoil, affecting blood flow. Option B (125 per minute) is also too fast and can lead to ineffective compressions. Option D (75 per minute) is too slow and may not generate enough force to circulate blood effectively. Educationally, it is important to teach healthcare providers the correct rate of chest compressions in infants to ensure they are prepared to respond in emergency situations. Understanding and practicing these guidelines can make a significant difference in the outcomes of pediatric patients in cardiac arrest. By reinforcing these principles through test questions, educators can help solidify this essential knowledge among students and healthcare professionals.

Correct Answer: D

Rationale: In pediatric nursing, understanding advanced life support is crucial for providing optimal care in emergency situations. The correct answer, option D, "Treatment of life-threatening arrhythmias," is not typically included in the immediate interventions of advanced life support for pediatric patients. Vascular access (option A) is important for administering medications or fluids rapidly in emergency situations. Fluid administration (option B) is vital for maintaining adequate perfusion and addressing hypovolemia. Breathing support (option C) is essential to ensure adequate oxygenation and ventilation. In an educational context, it's important to emphasize that while treating life-threatening arrhythmias is crucial in advanced cardiac life support, in pediatric patients, other interventions such as establishing vascular access, providing fluids, and ensuring proper breathing support take precedence in the initial stages of resuscitation. This distinction is critical to prevent delays in life-saving interventions and optimize outcomes for pediatric patients in emergency situations.

Correct Answer: B

Rationale: In pediatric nursing, understanding the signs and symptoms of shock is crucial for early identification and intervention. In the context of early (compensated) shock, the correct feature is tachycardia (Option B). Tachycardia is a compensatory mechanism the body employs to maintain perfusion and oxygen delivery to vital organs in response to decreased blood volume or pressure. Hypotension (Option A) is a feature of late (decompensated) shock when compensatory mechanisms fail. Decreased level of consciousness (Option C) and cold extremities (Option D) are also signs of late-stage shock when the body is unable to maintain perfusion adequately. Educationally, understanding the progression of shock from compensated to decompensated stages is vital for nurses caring for pediatric patients. Recognizing early signs like tachycardia can prompt timely interventions to prevent further deterioration and improve outcomes. This knowledge equips nurses to assess, intervene, and communicate effectively in emergency situations, ensuring the best possible care for pediatric patients in shock.

Correct Answer: C

Rationale: In pediatric nursing, understanding metabolic acidosis is crucial as it can have serious implications on a child's health. In this question, the correct answer is C) Renal tubular acidosis. Renal tubular acidosis (RTA) is a condition where the kidneys are unable to effectively excrete acids into the urine, leading to metabolic acidosis. This results in a high anion gap due to the accumulation of unmeasured anions. Therefore, RTA can cause metabolic acidosis with a high anion gap. A) Diabetic ketoacidosis (DKA) is a condition commonly seen in pediatric patients with diabetes. It leads to the production of ketones and metabolic acidosis with an elevated anion gap. B) Salicylate poisoning can also cause metabolic acidosis with a high anion gap due to the accumulation of salicylic acid. D) Renal failure can lead to metabolic acidosis, but typically with a normal anion gap, not a high anion gap. Educationally, understanding the causes of metabolic acidosis and the associated anion gap can help pediatric nurses in assessing and managing critically ill children. It is essential to differentiate between various etiologies of metabolic acidosis to provide prompt and appropriate interventions, emphasizing the importance of accurate clinical assessment and knowledge application in pediatric nursing practice.
