While assessing the newborn, the nurse should be aware that the average expected apical pulse range of a full-term, quiet, alert newborn is __ beats/min.
100 to 120
120 to 160
80 to 100
150 to 180
The Correct Answer is B
Choice a) 100 to 120 is incorrect because this is too low for a normal newborn's heart rate. The heart rate of a newborn is influenced by factors such as gestational age, activity level, temperature, and health status. A full-term, quiet, alert newborn should have a heart rate between 120 and 160 beats per minute, which reflects their high metabolic rate and oxygen demand. A heart rate below 100 beats per minute may indicate bradycardia, which can be caused by hypoxia, hypothermia, or cardiac problems.
Choice b) 120 to 160 is correct because this is the normal range for a full-term, quiet, alert newborn's heart rate. The apical pulse is the best way to measure the heart rate of a newborn, as it reflects the actual contractions of the heart. The apical pulse can be auscultated at the fourth intercostal space on the left side of the chest, just below the nipple line. The nurse should count the apical pulse for a full minute, as it may vary with the respiratory cycle.
Choice c) 80 to 100 is incorrect because this is also too low for a normal newborn's heart rate. A full-term, quiet, alert newborn should have a heart rate between 120 and 160 beats per minute, which is higher than that of an adult or an older child. A heart rate below 100 beats per minute may indicate bradycardia, which can be caused by hypoxia, hypothermia, or cardiac problems.
Choice d) 150 to 180 is incorrect because this is too high for a normal newborn's heart rate. A full-term, quiet, alert newborn should have a heart rate between 120 and 160 beats per minute, which is lower than that of a preterm or a crying newborn. A heart rate above 160 beats per minute may indicate tachycardia, which can be caused by fever, infection, anemia, or hyperthyroidism.

Correct Answer is D
Explanation
Choice A) Report of absent breast pain is incorrect because this is not a finding that indicates that the medication was effective, but rather a finding that indicates that the client does not have mastitis or engorgement. Mastitis is an infection of the breast tissue that causes pain, swelling, redness, and fever. Engorgement is a condition where the breasts become overfilled with milk, causing pain, hardness, and leakage. Both conditions are common in postpartum women who are breastfeeding, but they are not related to methylergonovine or uterine bleeding. Therefore, this response is irrelevant and inaccurate.
Choice B) Increase in lochia is incorrect because this is not a finding that indicates that the medication was effective, but rather a finding that indicates that the medication was ineffective or that the client has a complication. Lochia is the vaginal discharge that consists of blood, mucus, and tissue from the uterus after childbirth. It usually lasts for about 4 to 6 weeks and gradually decreases in amount and color. Methylergonovine is a medication that helps to control uterine bleeding by improving the tone and contractions of the uterus. An increase in lochia may mean that methylergonovine did not work well or that the client has a problem such as retained placenta, infection, or subinvolution. Therefore, this response is opposite and inaccurate.
Choice C) Increase in blood pressure is incorrect because this is not a finding that indicates that the medication was effective, but rather a finding that indicates that the client has a side effect or a risk factor. Blood pressure is the force of blood against the walls of the arteries. It is measured by two numbers: systolic (the pressure when the heart beats) and diastolic (the pressure when the heart rests). The normal range for blood pressure is 120/80 mm Hg or lower. Methylergonovine is a medication that can cause vasoconstriction, which means narrowing of the blood vessels and increasing of the blood pressure. This can lead to complications such as hypertension, stroke, or heart attack. Therefore, this response is adverse and inaccurate.
Choice D) Fundus firm to palpation is correct because this is a finding that indicates that the medication was effective and that the client has a good outcome. The fundus is the upper part of the uterus that can be felt through the abdomen after childbirth. It should be firm, midline, and at or below the level of the navel. A firm fundus means that the uterus has contracted well and stopped bleeding. Methylergonovine is a medication that helps to achieve this by improving the tone and contractions of the uterus. Therefore, this response is positive and accurate.
Correct Answer is D
Explanation
Choice A: This is incorrect because lanugo is a fine, downy hair that covers the fetus in utero. It usually disappears by the 36th week of gestation, but it may persist in some preterm infants. Lanugo helps to retain body heat and protect the skin from amniotic fluid. Lanugo is not a sign of postmaturity, but of prematurity or intrauterine growth restriction.
Choice B: This is incorrect because a short, chubby appearance is typical of a term infant, who is born between 37 and 42 weeks of gestation. A term infant has a well-developed subcutaneous fat layer that gives them a rounded shape and smooth skin. A term infant also has a head circumference that is proportional to their body length and weight. A short, chubby appearance is not a sign of postmaturity, but of normal development.
Choice C: This is incorrect because vernix caseosa is a white, cheesy substance that covers the fetus in utero. It usually decreases by the 40th week of gestation, but it may remain in some term infants, especially in the skin folds. Vernix caseosa helps to moisturize and protect the skin from amniotic fluid and infection. Vernix caseosa is not a sign of postmaturity, but of term or near-term gestation.
Choice D: This is the correct answer because cracked, peeling skin is a common sign of postmaturity, which occurs when the infant is born after 42 weeks of gestation. A postmature infant has a loss of subcutaneous fat and water that results in dry, wrinkled, and desquamated skin. A postmature infant also has a large head circumference that is disproportionate to their body length and weight. Cracked, peeling skin indicates prolonged exposure to amniotic fluid and placental insufficiency.
