A nurse applies a painful stimulus to the nailbeds of an unconscious patient. The patient responds with extension of the arms and legs, pronation of the arms, and plantar flexion. The nurse documents this as:
Decorticate posturing
Flexion withdrawal
Localization of pain
Decerebrate posturing
The Correct Answer is D
Choice A reason:
Decorticate posturing involves abnormal flexion of the arms towards the chest and extension of the legs. This posture indicates damage to the corticospinal tract at the level of the diencephalon. The described response does not match decorticate posturing.
Choice B reason:
Flexion withdrawal is a response to painful stimuli where the patient pulls away or flexes the affected limb. This is a less severe response than posturing and does not match the description provided in the scenario.
Choice C reason:
Localization of pain refers to the patient's ability to purposefully move a hand to the site of a painful stimulus, indicating higher brain function. The described response of arm and leg extension with pronation does not fit this description.
Choice D reason:
Decerebrate posturing is characterized by extension of the arms and legs, pronation of the arms, and plantar flexion. This posture indicates severe brainstem damage and is consistent with the described response.

Correct Answer is ["B","D","E"]
Explanation
Choice A reason:
Elevating the client's head on two pillows is not a standardized method for managing intracranial pressure. Instead, elevating the head of the bed to 30 degrees is a more effective strategy to promote venous drainage and reduce ICP.
Choice B reason:
Decreasing the noise level in the client's room helps create a calm environment, which can reduce stress and prevent increases in ICP. Excessive noise and stimulation can elevate intracranial pressure.
Choice C reason:
Frequent suctioning of the endotracheal tube can actually increase ICP due to the stimulation and potential for causing a cough reflex. Suctioning should be performed only as necessary and with care.
Choice D reason:
Administering a stool softener helps prevent straining during bowel movements, which can increase ICP. Ensuring regular and comfortable bowel movements is crucial in managing intracranial pressure.
Choice E reason:
Giving a 500cc NS fluid bolus can be appropriate in some clinical scenarios to maintain adequate blood pressure and perfusion. However, fluid management must be carefully balanced to avoid fluid overload, which could increase ICP. Generally, fluid boluses are not the primary method for managing ICP.
Correct Answer is D
Explanation
Choice A reason:
Using non-steroidal anti-inflammatory drugs (NSAIDs) for discomfort is not recommended for patients with heart failure because NSAIDs can cause fluid retention and worsen heart failure symptoms. They can also interfere with the effects of certain heart failure medications.
Choice B reason:
Limiting sodium in the diet to 3.5 g/day is not restrictive enough for heart failure patients. Typically, heart failure management involves reducing sodium intake to around 2-2.3 g/day to help prevent fluid retention and reduce the workload on the heart.
Choice C reason:
Placing the client in a lateral position is not specifically beneficial in the management of heart failure. While changing positions can be part of general patient care, it does not directly address the fluid balance or cardiac workload in heart failure patients.
Choice D reason:
Limiting fluid intake to 2 liters/day is a common intervention for managing heart failure. This helps to prevent fluid overload, which can exacerbate heart failure symptoms and lead to complications such as pulmonary edema. Maintaining a careful balance of fluid intake is essential for managing heart failure effectively.
