What clinical manifestations does the nurse recognize would be associated with a diagnosis of hyperthyroidism? Select all that apply.

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.

Choice A reason: Pink frothy sputum is a classic sign of pulmonary edema, which can occur as a result of oxygen toxicity. When the alveoli in the lungs fill with fluid, it can lead to this type of sputum. This is a critical indicator that the client is experiencing severe respiratory distress and requires immediate medical attention.

Choice B reason: Substernal discomfort or chest pain is another symptom of oxygen toxicity. This discomfort arises due to the irritation and inflammation of the lung tissues caused by high levels of oxygen. It is essential to monitor and address this symptom promptly to prevent further complications.

Choice C reason: Nail clubbing is typically associated with chronic hypoxia and long-term lung diseases, but it is not an acute indicator of oxygen toxicity. Therefore, it is not relevant in this context.

Choice D reason: Restlessness is a common early sign of hypoxia and can also indicate oxygen toxicity. When the brain does not receive adequate oxygen, it can lead to symptoms such as restlessness, confusion, and agitation. This symptom should be taken seriously and addressed immediately.

Choice E reason: Cyanosis at the nail beds indicates a lack of oxygen in the blood, but it is not specific to oxygen toxicity. It can occur in various conditions where there is inadequate oxygenation, such as chronic obstructive pulmonary disease (COPD) or heart failure.
