The nurse has just received a report on a group of clients on the neurosurgical unit. Which client is the nurse’s first priority?
Client who displays plantar flexion when the bottom of the foot is stroked.
Client who consistently demonstrates decortication when stimulated.
Client whose Glasgow Coma Scale (GCS) has changed from 15 to 12.
Client whose deep tendon reflexes have become hyperactive.
The Correct Answer is C
Choice A Reason:
The client who displays plantar flexion when the bottom of the foot is stroked is exhibiting a normal reflex response known as the plantar reflex. This response indicates that the corticospinal tract is functioning properly. In adults, the normal response is plantar flexion of the toes, which means the toes curl downward. This is not an immediate cause for concern and does not indicate a life-threatening condition.
Choice B Reason:
The client who consistently demonstrates decortication when stimulated is showing signs of severe brain injury. Decorticate posturing is characterized by the arms being flexed at the elbows and held tightly to the chest, with the legs extended and feet turned inward. This type of posturing indicates damage to the cerebral hemispheres, thalamus, or midbrain. While this is a serious condition, it is not necessarily the most immediate priority compared to a sudden change in the Glasgow Coma Scale.
Choice C Reason:
The client whose Glasgow Coma Scale (GCS) has changed from 15 to 12 is the nurse’s first priority. The GCS is a critical tool used to assess a patient’s level of consciousness, with scores ranging from 3 (deep coma) to 15 (fully awake and alert). A drop in GCS score indicates a significant decline in neurological function, which could be due to increased intracranial pressure, bleeding, or other acute changes in the brain. This requires immediate assessment and intervention to prevent further deterioration.
Choice D Reason:
The client whose deep tendon reflexes have become hyperactive is showing signs of hyperreflexia. Hyperactive reflexes can indicate an upper motor neuron lesion, which affects the descending corticospinal tract. While this is a concerning sign that warrants further investigation, it is not as immediately critical as a sudden change in the GCS score.

Correct Answer is D
Explanation
Choice A Reason:
Pronation of the hands.
Pronation of the hands is not typically associated with decorticate posturing. Decorticate posturing is characterized by the flexion of the arms and wrists, with the hands often clenched into fists. Pronation refers to the rotation of the hands so that the palms face downward, which is not a feature of decorticate posturing.
Choice B Reason:
Extension of the arms.
Extension of the arms is more characteristic of decerebrate posturing, not decorticate posturing. In decorticate posturing, the arms are flexed and held tightly to the chest, not extended. This flexion is due to damage to the cerebral hemispheres, which affects the corticospinal tract.
Choice C Reason:
External rotation of the lower extremities.
External rotation of the lower extremities is not a typical finding in decorticate posturing. In decorticate posturing, the legs are usually extended and rigid, with the toes pointed. External rotation would indicate a different type of posturing or neurological condition.
Choice D Reason:
Plantar flexion of the legs.
Plantar flexion of the legs is a characteristic finding in decorticate posturing. This involves the toes pointing downward, which is a result of the increased muscle tone and reflexes due to the brain injury. This posture indicates severe damage to the brain, specifically the corticospinal tract.

Correct Answer is ["E","F","G"]
Explanation
Choice A reason:
Hypertension is not typically associated with myxedema coma. Myxedema coma is characterized by severe hypothyroidism, which usually leads to low blood pressure (hypotension) rather than high blood pressure (hypertension). Therefore, hypertension is not a clinical manifestation that indicates progression to myxedema coma.
Choice B reason:
Restlessness is not a common symptom of myxedema coma. Patients with myxedema coma often present with lethargy, confusion, or even coma due to the severe slowing of metabolic processes. Restlessness is more commonly associated with hyperthyroidism or other conditions that increase metabolic activity.
Choice C reason:
An increased level of alertness is contrary to the symptoms of myxedema coma. Myxedema coma typically presents with decreased mental status, including confusion, stupor, or coma. Therefore, an increased level of alertness would not be indicative of progression to myxedema coma.
Choice D reason:
Tachycardia (rapid heart rate) is not a typical symptom of myxedema coma. Instead, myxedema coma is associated with bradycardia (slow heart rate) due to the severe hypothyroid state. Tachycardia is more commonly seen in hyperthyroid conditions.
Choice E reason:
Hypotension (low blood pressure) is a key clinical manifestation of myxedema coma. The severe hypothyroid state leads to decreased cardiac output and vascular resistance, resulting in hypotension. This is a critical sign that the nurse should recognize as indicative of progression to myxedema coma.
Choice F reason:
Bradycardia (slow heart rate) is another hallmark of myxedema coma. The decreased metabolic rate in severe hypothyroidism leads to a reduced heart rate. Recognizing bradycardia is essential in identifying the progression to myxedema coma.
Choice G reason:
Hypoventilation (reduced breathing rate) is a significant symptom of myxedema coma. The severe hypothyroid state can lead to respiratory depression, resulting in hypoventilation. This can further exacerbate the patient’s condition and requires immediate medical attention.
Choice H reason:
Hyperventilation (increased breathing rate) is not associated with myxedema coma. Patients with myxedema coma typically experience hypoventilation due to the severe slowing of metabolic processes. Hyperventilation would be more indicative of conditions that increase metabolic activity or respiratory drive.
