A nurse is evaluating a preterm infant who has patent ductus arteriosus (PDA).
Which of the following findings should indicate to the nurse that the condition is improving?
Decreased heart rate can be a sign of hypoxia, acidosis, or heart failure, which are complications of PDA.
Increased blood pressure can be a sign of increased systemic vascular resistance, which can result from decreased tissue perfusion due to PDA.
Decreased respiratory rate can be a sign of respiratory depression, which can be caused by some medications used to treat PDA, such as indomethacin or ibuprofen.
Increased oxygen saturation. This indicates that the condition is improving because it means that the blood is getting more oxygen in the lungs and less blood is shunting from the aorta to the pulmonary artery through the patent ductus arteriosus (PDA).
Increased oxygen saturation. This indicates that the condition is improving because it means that the blood is getting more oxygen in the lungs and less blood is shunting from the aorta to the pulmonary artery through the patent ductus arteriosus (PDA).
Choice A is wrong because decreased heart rate can be a sign of hypoxia, acidosis, or heart failure, which are complications of PDA.
Choice B is wrong because increased blood pressure can be a sign of increased systemic vascular resistance, which can result from decreased tissue perfusion due to PDA.
Choice C is wrong because decreased respiratory rate can be a sign of respiratory depression, which can be caused by some medications used to treat PDA, such as indomethacin or ibuprofen.
Normal ranges for oxygen saturation in preterm infants are between 88% and 95%.
Normal ranges for heart rate in preterm infants are between 120 and 160 beats per minute.
Normal ranges for blood pressure in preterm infants depend on gestational age and weight.
Normal ranges for respiratory rate in preterm infants are between 40 and 60 breaths per minute.
