Explanation
Signs: "increasingly confused and irritable", "tremors in the client's hands when arms are extended", "The client with cirrhosis appears disoriented and has difficulty answering simple asks", "The nurse observes asterixis when the client extends their arms", "The nurse monitors the client closely for worsening neurologic functions.”. Causes: "cirrhosis", "elevated mental status" (This phrase is likely a typo and should refer to elevated ammonia levels, which is the primary cause of hepatic encephalopathy). Treatments: "The provider prescribes lactulose to lower ammonia levels.”.
Correct Answer is B
Explanation
Choice A rationale
A newborn's heart rate typically ranges from 120 to 160 beats per minute, and respirations are normally between 30 and 60 breaths per minute. A heart rate of 160/min and respirations of 40/min fall within these normal physiological ranges for a newborn, indicating adequate cardiovascular and respiratory adaptation to extrauterine life.
Choice B rationale
The average head circumference for a full-term newborn ranges from 33 to 35 cm, and the chest circumference is typically 2 to 3 cm less than the head circumference. A head circumference of 40 cm is significantly larger than the normal range, and a chest circumference of 32 cm suggests an abnormal head-to-chest ratio. These measurements could indicate hydrocephalus or other developmental anomalies and warrant immediate reporting to the provider for further assessment.
Choice C rationale
A positive Babinski reflex, characterized by dorsiflexion of the big toe and fanning of the other toes, is a normal neurological finding in newborns and infants up to 12-24 months of age, indicating an immature corticospinal tract. A negative Ortolani's sign indicates the absence of hip dislocation or dysplasia, which is a normal and desired finding, reflecting stable hip joints.
Choice D rationale
Acrocyanosis, which is the bluish discoloration of the hands and feet, is a common and normal finding in newborns during the first 24 to 48 hours after birth due to immature peripheral circulation. Caput succedaneum, a localized swelling of the scalp that crosses suture lines, is also a common and benign finding resulting from pressure during vaginal birth, typically resolving spontaneously within a few days.
