What is the result of hypothermia in the newborn?
Decreased metabolic rate
Decreased oxygen demands
Shivering to generate heat
Increased glucose demands
The Correct Answer is D
Choice A) Decreased metabolic rate is incorrect because this is not a result of hypothermia in the newborn, but rather a cause of it. Metabolic rate is the speed at which the body uses energy to perform its functions. Newborns have a high metabolic rate, which helps them to maintain a normal body temperature of 36.5°C to 37.5°C (97.7°F to 99.5°F). However, some factors can lower the metabolic rate of newborns, such as prematurity, low birth weight, infection, or hypoglycemia. A low metabolic rate can make the newborn more susceptible to heat loss and hypothermia, which is a condition that occurs when the body temperature drops below 36°C (96.8°F). Therefore, this response is inaccurate and misleading.
Choice B) Decreased oxygen demands is incorrect because this is not a result of hypothermia in the newborn, but rather a consequence of it. Oxygen demand is the amount of oxygen that the body needs to function properly.
Newborns have a high oxygen demand, which helps them to support their growth and development. However, some factors can decrease the oxygen demand of newborns, such as hypothermia, sedation, or asphyxia. A low oxygen demand can impair the oxygen delivery and utilization by the tissues and organs, leading to hypoxia, acidosis, or organ failure. Therefore, this response is irrelevant and inaccurate.
Choice C) Shivering to generate heat is incorrect because this is not a result of hypothermia in the newborn, but rather a mechanism that is absent in them. Shivering is an involuntary contraction of the muscles that produces heat and raises the body temperature. It is a common response to cold exposure in adults and older children, but not in newborns. Newborns do not have the ability to shiver, as their muscles are immature and lack glycogen stores.
Instead, they rely on other methods to generate heat, such as non-shivering thermogenesis, which involves burning brown fat in certain areas of the body. Therefore, this response is irrelevant and inaccurate.
Choice D) Increased glucose demands is correct because this is a result of hypothermia in the newborn that can cause complications. Glucose demand is the amount of glucose that the body needs to produce energy and maintain its functions. Newborns have a high glucose demand, which helps them to support their metabolic rate and thermoregulation. However, some factors can increase the glucose demand of newborns, such as hypothermia, stress, or infection. A high glucose demand can deplete the glucose stores and cause hypoglycemia, which is a low level of glucose in the blood that can lead to seizures, brain damage, or death. Therefore, this response is clear and accurate.

Correct Answer is A
Explanation
Choice A: This is the correct answer because a hard and tender abdomen is a sign of concealed hemorrhage, which can lead to hypovolemic shock and fetal distress. The nurse needs to monitor the woman's blood loss, blood pressure, pulse, and fetal heart rate to detect any complications and intervene accordingly.
Choice B: This is incorrect because opioid pain medication can mask the signs of shock and fetal distress, and may also cause respiratory depression in both the mother and the fetus. Pain relief should be given after assessing the woman's condition and consulting with the physician.
Choice C: This is incorrect because documenting the findings is not a priority action. The nurse needs to act quickly to prevent further blood loss and fetal compromise, and report the findings to the physician.
Choice D: This is incorrect because relaxation techniques may not be effective in reducing the pain and anxiety caused by abruptio placentae. The nurse should provide emotional support and reassurance to the woman, but also focus on assessing and managing her physical condition.
Correct Answer is D
Explanation
Choice A) Placenta previa is incorrect because this is not a likely complication for a client who has gestational hypertension and reports continuous abdominal pain and vaginal bleeding. Placenta previa is a condition where the placenta covers part or all of the cervix, preventing normal delivery. It can cause painless, bright red bleeding in the third trimester, especially after intercourse or a pelvic exam. However, it does not cause abdominal pain, as the bleeding is not associated with uterine contractions or separation. Moreover, it is not related to gestational hypertension, which is a condition that causes high blood pressure during pregnancy. Therefore, this response is irrelevant and inaccurate.
Choice B) Incompetent cervix is incorrect because this is not a possible complication for a client who is at 36 weeks of gestation and has gestational hypertension and reports continuous abdominal pain and vaginal bleeding.
Incompetent cervix is a condition where the cervix is weak and unable to hold the pregnancy, leading to premature dilation and delivery. It can cause painless, watery vaginal discharge or spotting in the second trimester, followed by rupture of membranes and labor. However, it does not cause abdominal pain or heavy bleeding, as the cervix does not tear or detach from the uterus. Moreover, it is not related to gestational hypertension, which is a condition that causes high blood pressure during pregnancy. Therefore, this response is irrelevant and inaccurate.
Choice C) Prolapsed cord is incorrect because this is not a common complication for a client who has gestational hypertension and reports continuous abdominal pain and vaginal bleeding. Prolapsed cord is a condition where the umbilical cord slips through the cervix and into the vagina before the baby, compressing the cord and cutting off the blood supply and oxygen to the baby. It can cause variable or prolonged fetal heart rate decelerations, visible or palpable cord in the vagina, or fetal distress. However, it does not cause abdominal pain or bleeding, as the cord does not rupture or bleed. Moreover, it is not related to gestational hypertension, which is a condition that causes high blood pressure during pregnancy. Therefore, this response is irrelevant and inaccurate.
Choice D) Abruptio placentae is correct because this is a probable complication for a client who has gestational hypertension and reports continuous abdominal pain and vaginal bleeding. Abruptio placentae is a condition where the placenta separates from the uterine wall before delivery, causing hemorrhage and hypoxia for the mother and the baby. It can cause severe, constant abdominal pain, dark red bleeding, uterine tenderness or rigidity, fetal distress or demise, or maternal shock or coagulopathy. It can be triggered by gestational hypertension, which is a condition that causes high blood pressure during pregnancy and increases the risk of placental abruption by 25%. Therefore, this response is relevant and accurate.
