The primary clinical manifestation of scabies is:

Choice A reason: This statement is incorrect, as rechecking blood pressure and providing oxygen are not the immediate nursing priorities for a neonate with fever and signs of sepsis. Blood pressure is not a reliable indicator of perfusion in neonates, and oxygen saturation is already within normal range. The nurse should focus on identifying and treating the source of infection, preventing hypovolemia and shock, and monitoring the vital signs and blood glucose levels.

Choice B reason: This statement is incorrect, as administering aspirin and normal saline bolus are not the immediate nursing priorities for a neonate with fever and signs of sepsis. Aspirin is contraindicated in children under 18 years of age due to the risk of Reye syndrome, a rare but serious condition that affects the liver and brain. Normal saline bolus may be indicated for hypotension or shock, but only after obtaining blood cultures and starting antibiotics.

Choice C reason: This statement is incorrect, as administering antibiotics and oxygen are not the immediate nursing priorities for a neonate with fever and signs of sepsis. Antibiotics are essential for treating the infection, but they should be given after obtaining blood cultures to avoid false-negative results. Oxygen may be needed if the neonate develops hypoxia or respiratory distress, but it is not the first intervention for a neonate with normal oxygen saturation.

Choice D reason: This statement is correct, as obtaining blood cultures, providing IV fluids and antibiotics are the immediate nursing priorities for a neonate with fever and signs of sepsis. Blood cultures are necessary to identify the causative organism and guide the antibiotic therapy. IV fluids are needed to maintain hydration, perfusion, and electrolyte balance. Antibiotics are needed to eradicate the infection and prevent septic shock and organ failure.

Choice A reason: This is not a good choice. Adult heart disease can cause volume overload, but so can pediatric heart disease. Volume overload is a condition where the heart has to pump more blood than normal, which can lead to heart failure and pulmonary edema. Volume overload can be caused by various factors, such as valvular defects, hypertension, or anemia.

Choice B reason: This is the correct choice. Adult heart disease is usually acquired, meaning that it develops over time due to factors such as aging, lifestyle, or infection. Pediatric heart disease is usually congenital, meaning that it is present at birth due to genetic or environmental factors that affect the development of the heart.

Choice C reason: This is not a good choice. Heart failure can occur in both adult and pediatric heart disease. Heart failure is a condition where the heart cannot pump enough blood to meet the body's needs, which can lead to symptoms such as fatigue, shortness of breath, and edema. Heart failure can be caused by various factors, such as coronary artery disease, cardiomyopathy, or arrhythmias.

Choice D reason: This is not a good choice. Digoxin is a drug that can be used for both adults and children with heart disease. Digoxin is a cardiac glycoside that increases the force and efficiency of the heart contractions, slows down the heart rate, and improves the symptoms of heart failure. Digoxin can be used for conditions such as atrial fibrillation, heart failure, or congenital heart defects. However, digoxin has a narrow therapeutic range and requires careful monitoring of the blood levels and the patient's response.
