What are the expected signs of increased intracranial pressure (IICP)?

Correct Answer: A

Rationale: The correct answer is A: Restlessness, confusion, irritability. These are early signs of increased intracranial pressure (IICP) and require prompt intervention. Restlessness, confusion, and irritability are indicative of the brain's attempt to compensate for the rising pressure. Choice B is incorrect because severe headache alone is not specific to IICP and can be present in various conditions. Choice C is incorrect because elevated blood pressure is not a common sign of IICP; instead, hypertension may be present in the compensatory stage. Choice D is incorrect as bradycardia and altered pupil response are signs of advanced IICP, not early signs. Monitoring and recognizing these early signs are crucial for timely intervention and preventing further complications.

Correct Answer: A

Rationale: Flattened T waves are a characteristic ECG change seen in hyperkalemia. Hyperkalemia affects the repolarization phase of the cardiac cycle, leading to T wave abnormalities. Prominent U waves are typically seen in hypokalemia. Elevated ST segments are more indicative of myocardial infarction or pericarditis. Widened QRS complexes are commonly associated with conditions like bundle branch blocks or certain toxicities.

Correct Answer: A

Rationale: The correct teaching to provide to a patient after cataract surgery is to avoid NSAIDs. NSAIDs should be avoided to reduce the risk of bleeding post-surgery. Choices B, C, and D are not directly related to post-cataract surgery care. Avoiding bright lights and wearing dark glasses while outdoors may be beneficial for eye comfort but are not specific postoperative instructions. Using warm compresses is also not a standard teaching after cataract surgery.

Correct Answer: A

Rationale: The correct answer is A: Gradual loss of function on one side of the body. Thrombotic strokes are caused by a clot forming in a blood vessel supplying the brain, leading to a gradual onset of symptoms due to impaired blood flow to specific brain regions. Choices B, C, and D are incorrect because loss of sensation, sudden loss of consciousness, seizures, and convulsions are not typically associated with thrombotic strokes. In a thrombotic stroke, the symptoms develop slowly over time, often over minutes to hours, and include manifestations such as weakness, numbness, or paralysis on one side of the body, along with other symptoms related to the affected brain area.

Correct Answer: A

Rationale: The correct intervention for a patient with a chest tube and an air leak is to tighten the connections of the chest tube system. This step helps prevent air leaks and ensures the proper functioning of the chest tube. Choice B, replacing the chest tube, is not necessary as tightening the connections should be attempted first. Clamping the chest tube (Choice C) is not recommended as it can lead to complications by obstructing the drainage system. Continuing to monitor the chest tube (Choice D) without taking action may result in worsening of the air leak. Therefore, the priority intervention is to tighten the connections of the chest tube system.
