What action by the nurse is the most important action in preventing neonatal infection?

Choice A: This is incorrect because both physiological and nonphysiological jaundice result from breakdown of erythrocytes. Jaundice is caused by the accumulation of bilirubin, a yellow pigment that is produced when red blood cells are destroyed. However, the rate and extent of hemolysis differ between the two types of jaundice.

Choice B: This is incorrect because kernicterus is a rare and serious complication of jaundice, not a usual outcome. Kernicterus occurs when bilirubin levels are very high and the pigment deposits in the brain, causing neurological damage. It can affect both physiological and nonphysiological jaundice, but it is more likely to occur in nonphysiological jaundice due to higher bilirubin levels and underlying conditions.

Choice C: This is incorrect because both physiological and nonphysiological jaundice begin at the head and progress down the body. This is because bilirubin accumulates in areas with high fat content, such as the skin, eyes, and brain. The distribution of jaundice depends on the level of bilirubin in the blood, not on the type of jaundice.

Choice D: This is the correct answer because nonphysiological jaundice appears in the first 24 hours of life, whereas physiological jaundice appears after the first 24 hours of life. Nonphysiological jaundice is caused by factors that increase hemolysis or impair bilirubin metabolism or excretion, such as blood group incompatibility, infection, liver disease, or enzyme deficiency. Physiological jaundice is caused by normal adaptation processes that occur after birth, such as increased red blood cell turnover, immature liver function, and delayed intestinal flora colonization.

Choice a) Headaches is correct because this is a condition that can indicate a serious problem in the postpartum period and may require careful medical assessment. Headaches are common in the first few weeks after giving birth, but they can also be a sign of complications such as preeclampsia, eclampsia, cerebral venous thrombosis, meningitis, or aneurysm. Preeclampsia and eclampsia are conditions that cause high blood pressure, proteinuria, and seizures in pregnant or postpartum women. Cerebral venous thrombosis is a blood clot in the brain that can cause stroke-like symptoms. Meningitis is an infection of the membranes that cover the brain and spinal cord. Aneurysm is a bulge or rupture in a blood vessel that can cause bleeding in the brain. These conditions can be life-threatening and require immediate treatment. Therefore, women who experience severe, persistent, or unusual headaches in the postpartum period should seek medical attention as soon as possible.

Choice b) Varicosities of the legs is incorrect because this is not a condition that usually requires careful medical assessment in the postpartum period. Varicosities are enlarged or swollen veins that appear blue or purple under the skin. They are common in pregnancy due to increased blood volume, hormonal changes, and pressure from the growing uterus. They usually improve after delivery, but may persist or worsen in some women. Varicosities are usually harmless and do not cause any symptoms, but they may cause cosmetic concerns, discomfort, itching, or bleeding. They can also increase the risk of superficial thrombophlebitis, which is inflammation of a vein near the skin surface. However, these complications are rare and mild, and can be managed with conservative measures such as compression stockings, elevation of the legs, exercise, and painkillers. Therefore, women who have varicosities of the legs in the postpartum period do not need to worry too much, unless they have signs of infection or deep vein thrombosis, which is a more serious condition that involves a blood clot in a deep vein that can travel to the lungs and cause pulmonary embolism.

Choice c) Carpal tunnel syndrome is incorrect because this is not a condition that typically requires careful medical assessment in the postpartum period. Carpal tunnel syndrome is a condition that causes numbness, tingling, pain, or weakness in the hand and wrist due to compression of the median nerve that runs through a narrow passage called the carpal tunnel. It can occur in pregnancy due to fluid retention, hormonal changes, or repetitive movements. It usually resolves after delivery, but may persist or recur in some women. Carpal tunnel syndrome is usually mild and does not cause any serious complications, but it may interfere with daily activities or quality of life. It can be treated with conservative measures such as splinting, icing, massage, stretching, or painkillers. In severe cases, surgery may be needed to release the pressure on the nerve. Therefore, women who have carpal tunnel syndrome in the postpartum period do not need to seek medical attention urgently, unless they have signs of nerve damage or infection.

Choice d) Periodic numbness and tingling of the fingers is incorrect because this is not a condition that generally requires careful medical assessment in the postpartum period. Periodic numbness and tingling of the fingers can be caused by various factors such as cold exposure, poor circulation, nerve compression, vitamin deficiency, or anxiety.

It can also occur in pregnancy due to fluid retention or hormonal changes. It usually goes away after delivery, but may linger or come back in some women. Periodic numbness and tingling of the fingers is usually harmless and does not indicate any serious problem, but it may cause discomfort or annoyance. It can be relieved with simple measures such as warming up, moving around, shaking out the hands, taking supplements, or relaxing. Therefore, women who experience periodic numbness and tingling of the fingers in the postpartum period do not need to worry too much, unless they have signs of infection or neurological disorder.
