A patient admitted with acute renal failure asks for pain medication for a headache described as five out of ten on the pain scale. The nurse checks the MAR and sees that the only pain medication ordered is Ibuprofen. Which of the following actions should the nurse take first to ensure patient safety?

Choice A reason: Hypoglycemia typically presents with symptoms such as sweating, trembling, hunger, confusion, and in severe cases, loss of consciousness. The patient's symptoms of sudden right-sided weakness and difficulty speaking are more consistent with a neurological event rather than low blood sugar levels.

Choice B reason: Hemorrhagic stroke involves bleeding within the brain. Although it can present with similar symptoms to ischemic stroke, the diagnostic tests indicate no evidence of hemorrhage. This makes a hemorrhagic stroke less likely.

Choice C reason: Ischemic stroke occurs when a blood clot blocks a blood vessel in the brain, leading to reduced blood flow and oxygen to a part of the brain. The patient's symptoms of sudden right-sided weakness and expressive aphasia are classic signs of an ischemic stroke, and the absence of hemorrhage on the head CT scan supports this diagnosis.

Choice D reason: Multiple sclerosis (MS) is a chronic, progressive disease that affects the central nervous system. It usually presents with episodic neurological symptoms rather than the sudden onset seen in this patient. MS symptoms develop over time and can vary widely, whereas the patient's acute presentation is more indicative of a stroke.

Choice D reason: Elevating the head of the bed to 45 degrees is the first intervention the nurse should perform. This position helps lower the patient's blood pressure by promoting venous pooling in the lower extremities and reducing the return of blood to the heart. It also aids in better breathing and overall comfort.

Choice A reason: Checking the blood pressure is crucial in this situation to confirm if the patient is experiencing autonomic dysreflexia, which is characterized by a sudden and severe increase in blood pressure. This step helps in assessing the severity of the condition and guiding subsequent interventions.

Choice B reason: Obtaining a bladder scan is important because a full bladder is a common trigger of autonomic dysreflexia. By identifying and addressing the cause of the distension, the nurse can help alleviate the symptoms and prevent further complications.

Choice C reason: Notifying the doctor is a critical step, as autonomic dysreflexia is a medical emergency that requires prompt medical intervention. The healthcare provider can give additional orders and may administer medication to control the patient's blood pressure and relieve symptoms.
