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) 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 B
Explanation
Choice a) Document the event in the nurses' notes is incorrect because this is not a priority action for a neonate who is showing signs of hypoglycemia. Hypoglycemia is a condition where the blood glucose level is lower than normal, which can cause neurological and metabolic problems in newborns. Neonates of diabetic mothers are at higher risk of developing hypoglycemia due to increased insulin production and decreased glycogen stores.
Documenting the event in the nurses' notes is an important step, but it should be done after assessing and treating the neonate's condition.
Choice b) Test for blood glucose level is correct because this is the most important action for a neonate who is exhibiting symptoms of hypoglycemia. The nurse should use a heel stick or a cord blood sample to measure the blood glucose level of the neonate as soon as possible, as hypoglycemia can lead to serious complications such as seizures, coma, brain damage, or death if left untreated. The normal blood glucose range for a full-term neonate is 40 to 60 mg/dL in the first hour of life, and 50 to 90 mg/dL thereafter. A blood glucose level below 40 mg/dL indicates hypoglycemia and requires immediate intervention.
Choice c) Notify the clinician stat is incorrect because this is not the most urgent action for a neonate who is suffering from hypoglycemia. The nurse should notify the clinician after confirming the diagnosis of hypoglycemia and initiating treatment, such as feeding or administering intravenous glucose. The clinician may order further tests or treatments depending on the severity and cause of the hypoglycemia, but the nurse should not delay the initial management of the neonate's condition.
Choice d) Start an intravenous line with D5W is incorrect because this is not the first-line treatment for a neonate who has hypoglycemia. D5W stands for dextrose 5% in water, which is a solution that contains glucose and water. It can be used to treat hypoglycemia by providing a source of energy and fluid to the neonate. However, before starting an intravenous line with D5W, the nurse should first attempt to feed the neonate with breast milk or formula, as this can also raise the blood glucose level and provide other nutrients and antibodies. If feeding is unsuccessful or contraindicated, then the nurse should start an intravenous line with D5W as ordered by the clinician.
