The mother of a one-month-old infant calls the clinic to report that the back of her infant's head is flat. How should the nurse respond?
Position the infant on the stomach occasionally when awake and active.
Turn the infant on the left side braced against the crib when sleeping.
Place a small pillow under the infant's head while lying on the back.
Prop the infant in a sitting position with a cushion when not sleeping.
The Correct Answer is A
Choice A reason: Positioning the infant on the stomach occasionally when awake and active is the best response that the nurse can give to the mother. This is because it can help prevent and correct the flat head syndrome, also known as plagiocephaly, by taking pressure off the back of the head and allowing the skull to reshape naturally. It can also promote the infant's motor development and strengthen the neck and shoulder muscles. However, the nurse should also remind the mother to always place the infant on the back when sleeping, as this is the safest position to reduce the risk of sudden infant death syndrome (SIDS) .
Choice B reason: Turning the infant on the left side braced against the crib when sleeping is not a good response that the nurse can give to the mother. This is because it can increase the risk of SIDS, as the infant may roll over to the stomach or suffocate from the bedding or the crib. It can also worsen the flat head syndrome by creating another flat spot on the left side of the head.
Choice C reason: Placing a small pillow under the infant's head while lying on the back is not a good response that the nurse can give to the mother. This is because it can increase the risk of SIDS, as the pillow may cover the infant's face or cause the infant to overheat. It can also interfere with the natural reshaping of the skull and cause neck strain.
Choice D reason: Propping the infant in a sitting position with a cushion when not sleeping is not a good response that the nurse can give to the mother. This is because it can put too much pressure on the spine and the pelvis, which are still developing in the infant. It can also limit the infant's movement and exploration, which are important for learning and development.

Correct Answer is C
Explanation
Choice A reason: Encouraging the parents to rest when possible is not the first intervention that the nurse should instruct the mother to implement. While it is important for the parents to take care of themselves, the priority is to address the child's needs and comfort.
Choice B reason: Making a list of foods that the child likes is not the first intervention that the nurse should instruct the mother to implement. While it is important to maintain the child's nutrition and hydration, the child may not have an appetite due to the fever and inflammation caused by Kawasaki disease.
Choice C reason: Placing the child in a quiet environment is the first intervention that the nurse should instruct the mother to implement. This is because Kawasaki disease causes irritability and sensitivity to light and sound in the child. A quiet environment can help reduce the child's stress and discomfort.
Choice D reason: Applying lotion to hands and feet is not the first intervention that the nurse should instruct the mother to implement. While it is important to moisturize the skin and prevent cracking and infection, the lotion may not relieve the child's pain and inflammation.
Correct Answer is A
Explanation
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.
