The treatment of choice in a child with intussusception who is not showing signs of sepsis or shock is hydrostatic reduction of telescoped bowel with an air or saline enema. True or False?

Choice A reason: Increased stroke volume is not a correct answer as it means that the heart pumps more blood with each contraction. This would result in increased blood pressure and perfusion, not cool extremities, weak pulses, and low urine output.

Choice B reason: Cardiac arrhythmia is not a correct answer as it means that the heart beats irregularly or abnormally. This can cause palpitations, chest pain, or fainting, but not necessarily cool extremities, weak pulses, and low urine output.

Choice C reason: Decreased cardiac output is a correct answer as it means that the heart pumps less blood than the body needs. This can result from a ventricular septal defect, which causes blood to shunt from the left ventricle to the right ventricle, reducing the amount of oxygenated blood that reaches the tissues. This can cause cool extremities, weak pulses, and low urine output, as well as fatigue, poor growth, and shortness of breath.

Choice D reason: Cyanosis is not a correct answer as it means that the skin, lips, or nails turn blue due to low oxygen levels in the blood. This can occur in some cases of ventricular septal defect, especially if there is pulmonary hypertension or a reversal of the shunt. However, cyanosis is not a direct cause of cool extremities, weak pulses, and low urine output.

Choice A reason: This statement is incorrect, as 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. The nurse should use other methods to reduce the fever, such as acetaminophen, tepid sponge baths, or cooling blankets.

Choice B reason: This statement is incorrect, as hospital-acquired sepsis is unlikely in a 3-day-old infant, unless the infant was exposed to invasive procedures or devices, such as catheters, ventilators, or surgery. The nurse should consider other sources of infection, such as the maternal genital tract, the umbilical cord, or the skin.

Choice C reason: This statement is incorrect, as blood pressure is not an early indicator of sepsis, but a late sign of shock. The nurse should monitor the infant for other signs of sepsis, such as temperature instability, tachycardia, tachypnea, lethargy, poor feeding, irritability, or hypoglycemia.

Choice D reason: This statement is correct, as the most common cause of sepsis in neonates is vertical transmission from the mother during pregnancy, labor, or delivery. The nurse should obtain a history of the mother's prenatal care, infections, medications, or complications, and assess the infant for any congenital anomalies or risk factors.
