When evaluating the laboratory report of a 1-year-old infant's hematocrit, a healthcare provider compares it with the expected hematocrit range for this age group. What is the hematocrit of a healthy 12-month-old infant?
- A. 19% to 32%
- B. 29% to 41%
- C. 37% to 47%
- D. 42% to 69%
Correct Answer: C
Rationale: The correct hematocrit range for a healthy 12-month-old infant is between 37% to 47%. At this age, this range reflects the normal blood volume and red blood cell (RBC) levels in infants. Choice A (19% to 32%) is too low for a healthy hematocrit level in a 12-month-old. Choice B (29% to 41%) is also below the typical range for a 12-month-old. Choice D (42% to 69%) includes an upper limit that is higher than expected for a healthy infant, making it an incorrect option.

A 2-year-old child is admitted to the hospital with a diagnosis of Kawasaki disease. What is the primary goal of therapy during the acute phase?
- A. Preventing coronary artery aneurysms
- B. Reducing fever
- C. Improving cardiac function
- D. Preventing dehydration
Correct Answer: A
Rationale: The primary goal of therapy during the acute phase of Kawasaki disease is to prevent coronary artery aneurysms. Kawasaki disease is characterized by systemic vasculitis and the most serious complication is the development of coronary artery aneurysms. While reducing fever and improving cardiac function are important aspects of managing Kawasaki disease, the primary focus in the acute phase is to prevent the development of coronary artery aneurysms. Preventing dehydration is also essential but not the primary goal in managing Kawasaki disease.
The nurse is caring for a 10-year-old with Duchenne muscular dystrophy. As part of the plan of care, the nurse focuses on maintaining his cardiopulmonary function. Which intervention would the nurse implement to best promote maximum chest expansion?
- A. Deep-breathing exercises
- B. Upright positioning
- C. Coughing
- D. Chest percussion
Correct Answer: B
Rationale: Upright positioning is the most appropriate intervention to promote maximum chest expansion in a child with Duchenne muscular dystrophy. By keeping the child in an upright position, lung expansion is maximized, which improves breathing efficiency. Deep-breathing exercises may help with overall lung function but do not directly promote chest expansion. Coughing and chest percussion are more related to airway clearance and do not specifically address maximizing chest expansion.
While assessing a child admitted for an asthma attack, a nurse in the emergency department observes large welts and scars on the child's back. What additional information must be included in the nurse's assessment?
- A. History of an injury
- B. Signs of child abuse
- C. Presence of food allergies
- D. Recent recovery from chickenpox
Correct Answer: B
Rationale: The correct answer is B: Signs of child abuse. When a nurse observes large welts and scars on a child, it raises concern for possible child abuse. It is crucial for the nurse to assess further for signs of abuse, document findings, and report appropriately to protect the child. Choice A, history of an injury, is not specific to potential abuse and may not provide insight into the current situation. Choice C, presence of food allergies, is not directly related to the observed welts and scars. Choice D, recent recovery from chickenpox, is also unrelated to the signs of abuse and does not impact the immediate assessment of the child's safety.
What is a key assessment the nurse should perform for a 5-year-old child diagnosed with acute glomerulonephritis?
- A. Monitor blood glucose levels
- B. Monitor respiratory rate
- C. Monitor urine output
- D. Monitor for signs of infection
Correct Answer: C
Rationale: Monitoring urine output is crucial in assessing kidney function in a child with acute glomerulonephritis. In this condition, there is inflammation in the glomeruli of the kidneys, affecting their ability to filter waste and excess fluids from the blood. Monitoring urine output helps evaluate the kidneys' ability to excrete waste and maintain fluid balance. Options A, B, and D are less relevant in the context of acute glomerulonephritis. Monitoring blood glucose levels is more pertinent in conditions like diabetes, monitoring respiratory rate is important for respiratory conditions, and monitoring for signs of infection is crucial in cases of suspected infections but is not the primary assessment focus in acute glomerulonephritis.
What is an early sign of congestive heart failure that the nurse should recognize?
- A. Tachypnea
- B. Bradycardia
- C. Inability to sweat
- D. Increased urinary output
Correct Answer: A
Rationale: Tachypnea, which refers to rapid breathing, is an early sign of congestive heart failure. In heart failure, the heart's inability to pump efficiently can lead to fluid accumulation in the lungs, causing the child to breathe faster to try to compensate for the decreased oxygen exchange. Bradycardia (slow heart rate) is not typically associated with congestive heart failure; instead, it may indicate a different issue. Inability to sweat is not a common early sign of congestive heart failure. Increased urinary output is not a typical early sign of congestive heart failure; instead, it may be a sign of other conditions like diabetes or kidney issues.
