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 C
Explanation
Fullness of the bladder. A boggy uterus with the fundus above the umbilicus and deviated to the side indicates that the uterus is not contracting properly and may be displaced by a full bladder. A full bladder can interfere with uterine involution and increase the risk of postpartum hemorrhage. The nurse should assess the bladder and assist the patient to empty it if needed.
Choice A. Blood pressure is not the next assessment because it is not related to the position and tone of the uterus. Blood pressure may be affected by blood loss, but it is not a priority in this situation.
Choice B. Amount of lochia is not the next assessment because it is not related to the position and tone of the uterus. Lochia may be increased or decreased depending on the uterine contraction, but it is not a priority in this situation.
Choice D. Level of pain is not the next assessment because it is not related to the position and tone of the uterus. Pain may be present due to uterine cramping or other factors, but it is not a priority in this situation.
Correct Answer is C
Explanation
Tachycardia. Tachycardia is a sign of hypovolemic shock from postpartum hemorrhage, which occurs when the blood volume is reduced and the heart rate increases to compensate for the low cardiac output and tissue perfusion. Tachycardia is usually the first sign of hypovolemic shock, as it can occur even before a significant drop in blood pressure or other symptoms.
Choice A. Hypotension is incorrect because it is a late sign of hypovolemic shock, which occurs when the compensatory mechanisms fail to maintain adequate blood pressure and organ perfusion.
Choice B. Cold, clammy skin is incorrect because it is a sign of peripheral vasoconstriction, which occurs as a compensatory mechanism to divert blood flow to the vital organs. However, it is not specific to hypovolemic shock and can occur in other types of shock as well.
Choice D. Decreased urinary output is incorrect because it is a sign of renal impairment, which occurs as a result of reduced blood flow to the kidneys. However, it is not specific to hypovolemic shock and can occur in other types of shock or renal disorders as well.
