Correct Answer: A

Rationale: The correct answer is A: Restlessness, irritability, and confusion are early signs of increased intracranial pressure (IICP). These signs indicate that the brain is starting to experience pressure, often due to conditions such as trauma, tumors, or hemorrhage. Sudden onset of seizures (choice B) is not typically an early sign of IICP but can occur later as the pressure increases. Decreased heart rate and pupillary response (choice C) are more indicative of late-stage IICP as the brainstem becomes compromised. Loss of consciousness (choice D) is a late sign of IICP when the pressure has significantly increased and is causing significant brain dysfunction.

Correct Answer: A

Rationale: Corrected Answer: Muscle weakness is a common sign of hypokalemia. The nurse should monitor for muscle weakness as potassium plays a crucial role in muscle function. Choices B, C, and D are incorrect because although hypokalemia can lead to cardiac dysrhythmias, bradycardia, and even seizures in severe cases, muscle weakness is a more common and specific sign directly related to potassium levels.

Correct Answer: A

Rationale: The correct recommendation for a patient with GERD is to avoid mint and spicy foods. These types of foods can trigger acid reflux and worsen GERD symptoms. Choice B is incorrect as eating large meals before bed can increase the likelihood of acid reflux due to increased pressure on the lower esophageal sphincter. Choice C is also incorrect as consuming liquids with meals can cause distension in the stomach, potentially leading to reflux. Choice D is not directly related to GERD, as foods high in potassium are generally healthy and not specifically problematic for GERD patients.

Correct Answer: A

Rationale: Flattened T waves are an early indicator of hypokalemia on an ECG. Hypokalemia primarily presents with flattened T waves, not prominent U waves, widened QRS complexes, or tall T waves. Prominent U waves are associated with hypokalemia only in severe cases. Widened QRS complexes are more indicative of hyperkalemia, while tall T waves are seen in hyperkalemia as well.

Correct Answer: A

Rationale: A thrombotic stroke typically presents with a gradual loss of function on one side of the body. This gradual onset distinguishes it from a hemorrhagic stroke, which often manifests with sudden and severe symptoms like loss of consciousness (choice B), severe headache and confusion (choice C), or loss of sensation in the affected limb (choice D). Therefore, choices B, C, and D are not typically associated with thrombotic strokes.
