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
A. Dressing the infant in only a T-shirt and diaper is not recommended during phototherapy because it reduces the amount of skin exposed to the light, which is necessary for effective treatment. The infant should be minimally clothed to maximize light exposure.
B. Restricting parental and oral fluids is incorrect. Adequate hydration is crucial during phototherapy to prevent dehydration, as the treatment can increase fluid loss through the skin.
C. Keeping the infant supine at all times is not necessary. The infant should be repositioned frequently to ensure all areas of the skin are exposed to the phototherapy light, which helps in reducing bilirubin levels more effectively.
D. Keeping the infant's eyes covered under the light is essential to protect the eyes from potential damage caused by the intense phototherapy light. This is a standard practice to prevent retinal damage and other eye complications.
Correct Answer is D
Explanation
Choice a) Placenta previa is incorrect because this is a condition where the placenta partially or completely covers the cervix, which can cause painless vaginal bleeding in the third trimester. It is not related to trauma and does not require hospitalization unless bleeding occurs.
Choice b) Dehydration is incorrect because this is a condition where the body loses more fluid than it takes in, which can cause symptoms such as thirst, dry mouth, headache, fatigue, and dizziness. It is not a complication of pregnancy and can be prevented by drinking enough water and avoiding caffeine and alcohol.
Choice c) Gestational hypertension is incorrect because this is a condition where the blood pressure rises above 140/90 mmHg after 20 weeks of pregnancy, which can cause complications such as preeclampsia, eclampsia, and fetal growth restriction. It is not caused by trauma and can be managed by regular antenatal care and medication if needed.
Choice d) Abruptio placentae is correct because this is a condition where the placenta separates from the uterine wall before delivery, which can cause severe vaginal bleeding, abdominal pain, uterine contractions, and fetal distress. It is a life-threatening emergency that can be triggered by trauma and requires immediate delivery of the baby and treatment of shock and blood loss. Therefore, a woman who is 8 months pregnant and involved in a serious motor vehicle crash should be admitted to the hospital for observation for this complication.
