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.
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 D
Explanation
Wash hands before touching each baby. This is because hand hygiene is the most effective way to prevent infection transmission in the nursery. Hand hygiene should be performed before and after every patient contact, as well as before and after wearing gloves or handling equipment. Hand hygiene can be done by washing hands with soap and water or using alcohol-based hand rubs.
Choice A is not correct because adjusting room temperature between 75°F and 80°F is not a measure to protect newborns from infection. The room temperature should be maintained within a comfortable range for newborns, but it does not affect infection risk.
Choice B is not correct because wearing a disposable gown when giving infant care is not a measure to protect newborns from infection. Disposable gowns are part of contact precautions, which are used for patients with known or suspected infections that can be transmitted by direct or indirect contact. They are not necessary for routine infant care.
Choice C is not correct because keeping the newborn dressed warmly is not a measure to protect newborns from infection. Keeping the newborn dressed warmly can help prevent heat loss and hypothermia, but it does not affect infection risk.
Correct Answer is B
Explanation
Prevent infection of the eyes from vaginal bacteria. This is because some newborns can be exposed to bacteria such as gonorrhea or chlamydia during delivery, which can cause a serious eye infection called gonococcal ophthalmia neonatorum (GON). Applying an antibiotic ointment such as erythromycin or ilotycin can prevent GON and other less severe eye infections by killing the bacteria.
Choice A is not correct because the umbilical cord does not need antibiotic ointment to prevent infection. It should be kept clean and dry until it falls off naturally.
Choice C is not correct because the tear ducts are not affected by vaginal bacteria. They are small tubes that drain tears from the eyes to the nose.
Choice D is not correct because the urethra is not a common site of infection for newborns. The urethra is the tube that carries urine from the bladder to the outside of the body.
