Question 1 of 5
Children with severe traumatic brain injury (TBI) may experience autonomic dysfunction characterized by all the following EXCEPT
Correct Answer: D
Rationale: In children with severe traumatic brain injury (TBI), autonomic dysfunction can manifest as various physiological changes. In this case, the correct answer is D) lowered blood pressure. Autonomic dysfunction in severe TBI typically results in increased sympathetic activity, leading to elevated temperature, heart rate, and respiratory rate. Elevated temperature is a common response to stress and injury due to increased metabolic demands. Elevated heart rate is a compensatory mechanism to ensure adequate tissue perfusion in response to the stress of TBI. Elevated respiratory rate helps maintain appropriate oxygenation levels in the body under stress. Lowered blood pressure, on the other hand, is not a typical manifestation of autonomic dysfunction in severe TBI. In fact, hypotension is often a concerning sign as it can indicate poor perfusion to vital organs and tissues, exacerbating the already critical condition of the child. Educationally, understanding the manifestations of autonomic dysfunction in severe TBI is crucial for healthcare providers caring for these pediatric patients. Recognizing these signs promptly can help in initiating appropriate interventions to stabilize the child's condition and prevent further complications.
Question 2 of 5
A neonate has been diagnosed with caput succedaneum. Which statement is correct about this condition?
Correct Answer: D
Rationale: Caput succedaneum is a condition characterized by the swelling of tissue over the presenting part of the infant's head during delivery. It is commonly a result of prolonged labor or vacuum extraction. Unlike cephalohematoma, caput succedaneum does cross the cranial suture lines. This condition typically resolves within a few days to a week after birth without intervention. It is important to monitor the infant for any complications or signs of infection during the resolution process.
Question 3 of 5
The nurse is evaluating a female child with acute post streptococcal glomerulonephritis for signs of improvement. Which finding typically is the earliest sign of improvement?
Correct Answer: A
Rationale: In a child with acute post streptococcal glomerulonephritis, the earliest sign of improvement typically seen is an increased urine output. This is because one of the hallmark features of glomerulonephritis is decreased urine output (oliguria) or even anuria. As the condition improves, the kidneys start functioning better, leading to increased urine output. Monitoring urine output is crucial in assessing the renal function and overall improvement in patients with glomerulonephritis. While increased appetite, energy level, and decreased diarrhea are important indicators of a child's overall health status, they are not specific signs of improvement in the context of acute post streptococcal glomerulonephritis.
Question 4 of 5
The nurse is drawing blood from the diabetic patient for a glycosylated hemoglobin test. She explains to the woman that the test is used to determine:
Correct Answer: C
Rationale: The correct answer is C. The glycosylated hemoglobin (HbA1c) test is used to determine the average glucose levels over the past several months (approximately 2-3 months). This test measures the amount of glucose that has been bound to hemoglobin in red blood cells, providing an indication of the patient's overall blood sugar control. This is particularly important for diabetic patients, as it helps healthcare providers assess the effectiveness of the management plan and make necessary adjustments to prevent complications associated with high blood sugar levels over time. The other options provided do not accurately describe what the glycosylated hemoglobin test measures.
Question 5 of 5
Spina bifida is one of the possible neural tube defects that can occur during early embryological development. Which of the following definitions most accurately describes meningocele? A.Complete exposure of spinal cord and meninges
Correct Answer: B
Rationale: Meningocele is a type of neural tube defect in which there is herniation of the meninges (protective membranes surrounding the brain and spinal cord) through a defect in the spinal column. This results in the formation of a sac-like protrusion that contains the meninges and cerebrospinal fluid but does not involve the spinal cord itself. In meningocele, the spinal cord remains in its normal position within the spinal canal. This condition is typically associated with spina bifida, a neural tube defect that occurs during early embryological development. Unlike myelomeningocele, which involves both the spinal cord and meninges protruding through the spinal column, meningocele specifically refers to the presence of a sac containing the meninges and spinal fluid without direct involvement of the spinal cord.
