One of the following is a bad prognostic criterion of acute lymphoblastic leukemia:

Correct Answer: D

Rationale: In the context of pediatric acute lymphoblastic leukemia (ALL), the correct answer is D) Male sex being a bad prognostic criterion. Male sex is associated with a poorer prognosis in pediatric ALL due to biological differences in how the disease presents and responds to treatment between males and females. Males tend to have a higher risk of relapse and poorer outcomes compared to females. Option A) Leukocytes 2000 /mm³ is not a bad prognostic criterion, as a lower leukocyte count is generally considered a favorable prognostic factor in pediatric ALL. Option B) Age 5 years is not a bad prognostic criterion either, as younger age at diagnosis is typically associated with a better prognosis in pediatric ALL. Option C) White race is not a bad prognostic criterion in pediatric ALL. Race does not inherently impact prognosis in ALL; rather, factors such as genetics and access to healthcare may play a role. In an educational context, understanding prognostic factors in pediatric ALL is crucial for healthcare providers caring for children with this condition. Recognizing these factors helps guide treatment decisions and allows for better prognostication and management of the disease. By knowing which factors are associated with poorer outcomes, healthcare providers can tailor treatment plans to optimize patient outcomes.

Correct Answer: C

Rationale: In pediatric nursing, accurate blood pressure measurement is crucial for assessing a child's health status. The appropriate cuff width is essential to obtain an accurate reading. In this case, the correct answer is C) 6 cm. This cuff width is suitable for a child with a mid-arm circumference of 15 cm because the cuff should cover about 80% of the arm's circumference. Using a cuff that is too narrow (options A and B) can lead to falsely elevated blood pressure readings as it increases the pressure in the artery. On the other hand, using a cuff that is too wide (option D) can result in falsely low readings due to inadequate compression of the artery. Educationally, understanding the correct cuff size for blood pressure measurement in children is vital for nurses and healthcare providers. It ensures accurate assessment and appropriate intervention if needed. Proper training and practice are necessary to master this skill and provide quality care to pediatric patients.

Correct Answer: B

Rationale: In the context of pediatric nursing and assessing oxygen saturation levels, an oxygen saturation of 90% indicates that ninety percent of hemoglobin is carrying oxygen (Option B). This is the correct answer because oxygen saturation represents the percentage of hemoglobin binding sites that are occupied by oxygen molecules. In this case, 90% saturation means that a significant portion of the available hemoglobin is carrying oxygen, which is essential for oxygen delivery to tissues and organs in the body. Option A, stating that the PaO2 is 90 mmHg, is incorrect because oxygen saturation and PaO2 measure different aspects of oxygen levels in the blood. PaO2 refers to the partial pressure of oxygen in arterial blood, not the percentage of hemoglobin carrying oxygen. Option C, suggesting that the child is breathing 90% oxygen, is incorrect because oxygen saturation reflects the amount of oxygen bound to hemoglobin, not the concentration of oxygen in the inhaled air. Option D, claiming that you cannot give more than 10% oxygen, is also incorrect as it does not align with the interpretation of oxygen saturation levels. In a clinical setting, understanding oxygen saturation levels is crucial for assessing respiratory function and oxygenation status in pediatric patients. Nurses and healthcare providers use this information to monitor the effectiveness of oxygen therapy, identify hypoxemia, and make informed decisions about the need for supplemental oxygen or other interventions to support oxygenation. By interpreting oxygen saturation values accurately, healthcare professionals can provide safe and effective care for pediatric patients with respiratory compromise or other oxygenation issues.

Correct Answer: B

Rationale: In this pediatric NCLEX practice quiz question, the correct answer is B) Marked tachypnea with recessions. This option is more in favor of respiratory distress rather than circulatory failure. Tachypnea with retractions is a common sign of respiratory distress in children, indicating the body's effort to compensate for inadequate oxygenation. Option A) Cyanosis despite supplied O2 is indicative of poor oxygenation despite oxygen therapy, which is a sign of circulatory failure. Option C) Gallop rhythm/murmur and Option D) Enlarged tender liver are also signs of circulatory failure, suggesting heart-related issues causing inadequate perfusion and circulation. Educationally, understanding the differences between signs of respiratory distress and circulatory failure is crucial for pediatric nursing practice. Recognizing these signs promptly can help nurses provide appropriate interventions and prevent further complications in pediatric patients. It's essential for nurses to be able to differentiate between respiratory and circulatory issues to provide effective and timely care to children in various healthcare settings.

Correct Answer: A

Rationale: In this question, the correct answer is A) Cardiogenic shock. Cardiogenic shock is not associated with decreased central venous pressure because it is caused by the heart's inability to pump effectively, leading to poor perfusion of tissues. This results in elevated central venous pressure due to blood backing up in the venous system. Hypovolemic shock (answer B) is associated with decreased central venous pressure because there is a loss of intravascular volume leading to decreased blood flow to tissues. Septic shock (answer C) is associated with decreased central venous pressure due to systemic vasodilation and increased vascular permeability. Distributive shock (answer D) is also associated with decreased central venous pressure as it involves widespread vasodilation and maldistribution of blood flow. Educationally, understanding the different types of shock and their associated hemodynamic changes is crucial for nurses caring for pediatric patients. Recognizing the specific characteristics of each type of shock can help nurses intervene promptly and effectively to stabilize the patient's condition. This knowledge is vital for providing safe and competent care to pediatric patients in critical situations.
