A nurse is providing dietary instructions to a client who has cardiovascular disease. The nurse should identify that which of following statements by the client indicates an understanding of the teaching?

A) Restlessness:
Restlessness is an early sign of increased intracranial pressure (ICP). It results from the brain's initial response to the pressure changes, which can cause alterations in mental status, such as confusion, agitation, or anxiety. Identifying restlessness early allows for timely intervention to prevent further complications.

B) Papilledema:
Papilledema is the swelling of the optic disc due to increased ICP, but it typically develops later in the progression of the condition. It is often observed on a fundoscopic examination and indicates more prolonged or severe intracranial hypertension.

C) Projectile vomiting:
Projectile vomiting can occur with increased ICP but is usually a later sign. It is associated with pressure on the brainstem and is often accompanied by other severe symptoms, such as headache and changes in consciousness.

D) Decorticate posturing:
Decorticate posturing is a late sign of increased ICP and indicates significant brain injury or herniation. It involves abnormal flexion of the arms and extension of the legs, reflecting severe damage to the corticospinal tract.

A) "It becomes easier when exercise is a routine."
While regular exercise can improve overall fitness and glucose control, this response does not address the client's immediate symptoms of diaphoresis, palpitations, and exhaustion, which could be related to hypoglycemia.

B) "Did you decrease your insulin intake before you exercised?"
This response is appropriate as it addresses a potential cause of the client's symptoms. Exercise increases insulin sensitivity and glucose uptake, which can lead to hypoglycemia if insulin levels are not adjusted appropriately. The client's symptoms may indicate that their blood sugar is too low, possibly due to insufficient adjustment of insulin.

C) "Were you careful to not have carbohydrates after the run?"
This response is less relevant because it focuses on the post-exercise period rather than the immediate symptoms the client is experiencing. Ensuring adequate carbohydrate intake after exercise is important, but the client's current symptoms suggest an issue related to blood sugar levels during or immediately after exercise.

D) "It is normal to feel this way after a morning run."
This response dismisses the client's symptoms and does not provide a helpful explanation or solution. The client’s symptoms might be indicative of hypoglycemia, which is a serious condition that requires immediate attention.
