Which signs are manifestations of the Cushing triad? Select all that apply.

Choice A rationale

Encouraging adequate water intake is important for overall health, but it does not directly address the client’s fear of undergoing an EEG. Adequate hydration can ensure better conduction of electrical signals, but it has no bearing on the client's anxiety related to a past electrocution incident. Therefore, it would not be effective in alleviating the client's specific fear regarding the EEG procedure.

Choice B rationale

Distracting the client’s attention from the test may temporarily reduce anxiety, but it does not address the underlying fear. The client’s fear stems from a misunderstanding of the EEG procedure, and distraction will not resolve this. It is more effective to provide factual information to dispel the fear.

Choice C rationale

Informing the client that they will not experience any electrical shock is a crucial step in alleviating their fear. An EEG records brain activity through electrodes placed on the scalp; it does not involve sending electrical currents into the body. Clarifying this fact helps address the root cause of the client’s fear, providing reassurance and reducing anxiety.

Choice D rationale

Informing the client that they will experience only mild electrical shock is incorrect and misleading. An EEG does not deliver any electrical shock to the client. Providing inaccurate information could increase the client’s anxiety and distrust. Proper education about the procedure's safety is essential for alleviating the client’s fear.

Choice A rationale

Normal posture involves relaxed and symmetrical positioning of the limbs without any abnormal flexion or extension.

Choice B rationale

Decorticate posturing is characterized by abnormal flexion of the upper extremities at the elbows and wrists, and extension of the lower extremities, often indicating damage to the corticospinal tract.

Choice C rationale

Decerebrate posturing involves extension and outward rotation of both the arms and legs, indicating damage to the brain stem, which is more severe than decorticate posturing.

Choice D rationale

Flaccid posture refers to a complete lack of muscle tone and resistance, often seen in severe cases of neurological damage or after a stroke. .
