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 B

Explanation

Fundus firm, at the level of the umbilicus. This is because the normal postpartum uterine fundus location should be around the belly button (umbilicus) one hour after delivery and then decrease by 1 cm per 24 hours. A firm fundus indicates that the uterus is contracting well and preventing bleeding.

Choice A is wrong because a soft fundus indicates uterine atony, which is a risk factor for hemorrhage.

Choice C is wrong because the fundus should not be above the umbilicus 12 hours after delivery.

Choice D is wrong because a fundus to the right of the umbilicus indicates a full bladder, which can displace the uterus and cause bleeding.

A. Lochia alba B. Lochia normal C. Lochia serosa D. Lochia rubra

Correct Answer is D

Explanation

This is because lochia rubra is the first stage of lochia, the vaginal discharge after giving birth. It comprises blood, shreds of fetal membranes, decidua, vernix caseosa, lanugo, and membranes. It is red in color because of the large amount of blood it contains. It lasts 1 to 4 days after birth.

Choice A is not correct because lochia alba is the last stage of lochia. It is whitish or yellowish-white in color and contains fewer red blood cells and more leukocytes, epithelial cells, cholesterol, fat, mucus, and microorganisms. It lasts from the second through the third to sixth weeks after delivery.

Choice B is not correct because there is no such thing as lochia normal. Lochia has three stages: lochia rubra, lochia serosa and lochia alba.

Choice C is not correct because lochia serosa is the second stage of lochia. It is brownish or pink in color and contains serous exudate, erythrocytes, leukocytes, cervical mucus, and microorganisms. It lasts for 4 to 12 days after delivery.
