A school-age child with nephrotic syndrome is receiving salt-poor human albumin IV. Which findings indicate to the nurse that the child is manifesting a therapeutic response?

Choice A reason: The lumen of the aorta reduces the volume of blood flow to the lower extremities is the correct pathophysiologic mechanism that supports the findings. This is because coarctation of the aorta is a congenital condition that causes a narrowing of the aorta, usually near the ductus arteriosus. This results in increased resistance to blood flow from the heart to the lower body, leading to higher blood pressure and stronger pulses in the upper extremities and lower blood pressure and weaker pulses in the lower extremities.

Choice B reason: The aortic semilunar valve obstructs blood flow into the systemic circulation is not the correct pathophysiologic mechanism that supports the findings. This is because the aortic semilunar valve is located at the base of the aorta and prevents blood from flowing back into the left ventricle. If the valve is obstructed, it would cause aortic stenosis, which is a different condition from coarctation of the aorta. Aortic stenosis would cause symptoms such as chest pain, shortness of breath, and fainting.

Choice C reason: The pulmonic valve prevents adequate blood volume into the pulmonary circulation is not the correct pathophysiologic mechanism that supports the findings. This is because the pulmonic valve is located at the base of the pulmonary artery and prevents blood from flowing back into the right ventricle. If the valve is obstructed, it would cause pulmonic stenosis, which is a different condition from coarctation of the aorta. Pulmonic stenosis would cause symptoms such as cyanosis, fatigue, and heart murmur.

Choice D reason: An opening in the atrial septum causes a murmur due to a turbulent left to right shunt is not the correct pathophysiologic mechanism that supports the findings. This is because an opening in the atrial septum is a defect in the wall that separates the two upper chambers of the heart. It would cause a condition called atrial septal defect, which is different from coarctation of the aorta. Atrial septal defect would cause symptoms such as difficulty breathing, frequent respiratory infections, and heart palpitations.

Choice A reason: Asking the boy to describe a typical day at school is the best intervention that the nurse can implement. This can help the nurse identify any possible sources of stress or anxiety that may be causing the boy's physical symptoms. The nurse can also provide emotional support and guidance to the boy and his parents on how to cope with the school-related challenges.

Choice B reason: Conducting a complete neurological assessment is not the best intervention that the nurse can implement. This is not necessary unless the boy has other signs of neurological problems, such as seizures, vision changes, or altered mental status. A neurological assessment may also be invasive and uncomfortable for the boy and may increase his anxiety.

Choice C reason: Counseling the parents to pay more attention to the child is not the best intervention that the nurse can implement. This may imply that the parents are neglectful or irresponsible, which may not be true. The nurse should avoid making assumptions or judgments about the parents' behavior and instead collaborate with them to find the best solutions for the child's well-being.

Choice D reason: Comparing the child's vital signs over the past three weeks is not the best intervention that the nurse can implement. This may not provide much useful information, as the child's vital signs may vary depending on the time of day, activity level, and emotional state. The nurse should focus more on the child's subjective complaints and psychosocial factors.
