The difference between physiological and nonphysiological jaundice is that nonphysiological jaundice
results from breakdown of erythrocytes
usually results in kernicterus
begins at the head and progresses down the body
appears in the first 24 hours of life
The Correct Answer is D
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.

Correct Answer is D
Explanation
Choice a) Urine output of 200 mL for the past 8 hours is incorrect because this is a normal finding for a postpartum woman. The average urine output for a healthy adult is about 800 to 2000 mL per day, which means about 100 to 250 mL per hour. Therefore, a urine output of 200 mL for the past 8 hours is within the normal range and does not indicate any complications.
Choice b) Weight decrease of 2 pounds since delivery is incorrect because this is also a normal finding for a postpartum woman. The weight loss is due to the expulsion of the placenta, amniotic fluid, and blood during delivery. A postpartum woman can expect to lose about 10 to 12 pounds immediately after giving birth, and another 5 pounds in the following weeks due to fluid loss. Therefore, a weight decrease of 2 pounds since delivery is not a cause for concern and does not need to be reported to the obstetrician.
Choice c) Pulse rate of 65 beats per minute is incorrect because this is also a normal finding for a postpartum woman. The normal resting pulse rate for an adult ranges from 60 to 100 beats per minute, and it may decrease slightly after delivery due to blood loss and reduced cardiac output. Therefore, a pulse rate of 65 beats per minute is not indicative of any problems and does not require any intervention.
Choice d) Drop in hematocrit of 6% since admission is correct because this is an abnormal finding for a postpartum woman and suggests that she has developed anemia due to excessive blood loss. Hematocrit is the percentage of red blood cells in the blood, and it reflects the oxygen-carrying capacity of the blood. The normal hematocrit range for an adult female is 37% to 47%, and it may decrease slightly after delivery due to hemodilution. However, a drop in hematocrit of more than 10% from the baseline or below 30% indicates severe anemia and requires immediate treatment. Therefore, a drop in hematocrit of 6% since admission is a significant change that should be reported to the obstetrician as soon as possible.

Correct Answer is A
Explanation
Choice a) This could result in profound bleeding is correct because this is the primary reason why an internal examination should be avoided for a client who has placenta previa. Placenta previa is a condition where the placenta covers part or all of the cervix, preventing normal delivery. An internal examination involves inserting a gloved finger or a speculum into the vagina and cervix to assess their dilation, effacement, position, and station. This can cause trauma to the cervix or the placenta, which can trigger severe hemorrhage and endanger the mother and the fetus. Therefore, this explanation is accurate and appropriate.
Choice b) This could initiate preterm labor is incorrect because this is not the main reason why an internal examination should be avoided for a client who has placenta previa. Placenta previa is a condition where the placenta covers part or all of the cervix, preventing normal delivery. An internal examination may stimulate uterine contractions, which can lead to preterm labor and delivery. However, this is not the most serious or likely complication of an internal examination for a client who has placenta previa, as the bleeding risk is much higher and more urgent. Therefore, this explanation is incomplete and misleading.
Choice c) There is an increased risk of introducing infection is incorrect because this is not a specific reason why an internal examination should be avoided for a client who has placenta previa. Placenta previa is a condition where the placenta covers part or all of the cervix, preventing normal delivery. An internal examination may introduce bacteria or other microorganisms into the vagina or cervix, which can cause infection and inflammation. However, this is a general risk that applies to any pregnant woman who undergoes an internal examination, not just those who have placenta previa. Therefore, this explanation is irrelevant and inaccurate.
Choice d) There is an increased risk of rupture of the membranes is incorrect because this is not a relevant reason why an internal examination should be avoided for a client who has placenta previa. Placenta previa is a condition where the placenta covers part or all of the cervix, preventing normal delivery. An internal examination may cause rupture of the membranes, which are the sacs that contain the amniotic fluid and the fetus. However, this is not a significant or common complication of an internal examination for a client who has placenta previa, as the membranes are usually located above or away from the placenta and cervix. Therefore, this explanation is improbable and inaccurate.
