To prevent possible retinopathy in a preterm infant requiring oxygen therapy, the nurse will:

Keep the infant's eyes covered at all times.

Position with the head slightly lower than the body.

Administer low concentrations of oxygen.

Monitor arterial oxygen levels with a pulse oximeter.

Answer and Explanation

The Correct Answer is C

Administer low concentrations of oxygen. Retinopathy of prematurity (ROP) is a disease of retinal vascular and capillary proliferation affecting premature infants undergoing oxygen therapy. Oxygen treatment results in pathologic growth of vessels in the developing retina that may lead to permanent damage to the retina as well as retinal detachment and macular folds. Administering low concentrations of oxygen can help prevent ROP by reducing the oxygen-induced vasoconstriction and vascular endothelial growth factor (VEGF) expression.

Choice A is not correct because keeping the infant's eyes covered at all times does not prevent ROP. In fact, it may increase the risk of infection or injury to the eyes.

Choice B is not correct because positioning with the head slightly lower than the body does not prevent ROP. It may increase the intracranial pressure and affect the cerebral blood flow.

Choice D is not correct because monitoring arterial oxygen levels with a pulse oximeter does not prevent ROP. It is a useful tool to guide oxygen therapy, but it does not directly affect retinal vascular development.

Correct Answer is A

Explanation

Endometritis. This is because the client's symptoms suggest that she has endometritis, which is an infection of the lining of the uterus. Endometritis is a common postpartum complication that can occur after vaginal or cesarean delivery. The client may also have foul-smelling vaginal discharge, chills, and fatigue.

Choice B is wrong because cystitis is an infection of the bladder that causes pain or burning during urination, not cramping.

Choice C is wrong because dehydration does not cause fever or persistent cramping.

Choice D is wrong because hypovolemic shock is a condition of low blood volume that causes low blood pressure, rapid pulse, and pale skin, not fever or cramping.

A. Mucus draining from the nose B. Cyanosis of the hands and feet C. Irregular heart rate D. Sternal or chest retractions

Correct Answer is D

Explanation

Sternal or chest retractions. This is because sternal or chest retractions are a sign of respiratory distress in newborns, which means they are having difficulty breathing. Chest retractions occur when the baby's chest pulls in with each breath, indicating that they are using extra muscles to breathe. This can be caused by various conditions that affect the lungs, such as respiratory distress syndrome (RDS), transient tachypnea of the newborn (TTN), meconium aspiration syndrome (MAS), pneumonia, or congenital heart defects.

Choice A is not correct because mucus draining from the nose is not a symptom of respiratory distress in newborns. It is normal for newborns to have some mucus in their nose and mouth after birth, which can be cleared by suctioning or wiping.

Mucus drainage does not interfere with breathing unless it is excessive or thick.

Choice B is not correct because cyanosis of the hands and feet is not a symptom of respiratory distress in newborns. It is normal for newborns to have bluish discoloration of their hands and feet, called acrocyanosis, for the first few days after birth. This is due to immature circulation and does not indicate a lack of oxygen. Cyanosis of the central parts of the body, such as the face, lips, and tongue, is more concerning and should be reported.

Choice C is not correct because irregular heart rate is not a symptom of respiratory distress in newborns. It is normal for newborns to have some variations in their heart rate, especially during sleep cycles. The normal heart rate range for newborns is 100 to 160 beats per minute. A heart rate that is too fast (tachycardia) or too slow (bradycardia) may indicate a problem with the heart or other organs³.
