Correct Answer: D

Rationale: The correct answer is D, pubic bone malformation. Exstrophy of the bladder is commonly associated with pubic bone malformation because the condition involves a defect in the pelvic region. Choices A, B, and C are incorrect. Imperforate anus, absence of one kidney, and congenital heart disease are not typically associated with exstrophy of the bladder.

Correct Answer: C

Rationale: In a child diagnosed with acute glomerulonephritis, monitoring urine output is a crucial assessment. Acute glomerulonephritis affects the kidneys, leading to decreased urine output due to impaired kidney function. Monitoring urine output helps assess renal perfusion, fluid status, and kidney function. This assessment is essential in determining the effectiveness of treatment and identifying complications. Monitoring blood glucose levels (Choice A) is not directly related to acute glomerulonephritis. Respiratory rate (Choice B) may be important in other conditions but is not a key assessment for acute glomerulonephritis. Monitoring for signs of infection (Choice D) is important in general, but it is not specific to the primary issue of impaired kidney function in acute glomerulonephritis.

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.

Correct Answer: A

Rationale: In this scenario, the infant is presenting with signs of respiratory distress, as evidenced by the increased work of breathing. Lowering the extremities can help reduce the workload on the diaphragm and improve respiratory mechanics. This action can be beneficial in optimizing the infant's breathing before considering more invasive interventions. Option B, initiating positive pressure ventilations, should be considered if the infant's condition deteriorates further and not as the first step. Option C, placing a nasopharyngeal airway and increasing oxygen flow, is not indicated as the primary intervention for increased work of breathing. Option D, listening to the lungs with a stethoscope, may provide additional information but is not the most urgent action needed in this situation.

Correct Answer: D

Rationale: Rapid acting insulin will help lower the elevated blood glucose level quickly.
