Correct Answer: A

Rationale: Restlessness, irritability, and confusion are early signs of increased intracranial pressure (IICP). These symptoms occur due to the brain's increased pressure within the skull. Sudden onset of seizures (Choice B) is not typically associated with increased intracranial pressure. Bradycardia and altered pupil response (Choice C) are signs of advanced or worsening IICP. Loss of consciousness (Choice D) is a late sign of increased intracranial pressure.

Correct Answer: A

Rationale: When continuous bubbling is observed in the chest tube water seal chamber, the correct intervention is to tighten the connections of the chest tube system. This can help resolve an air leak that is causing the continuous bubbling. Clamping the chest tube or replacing the entire chest tube system are not appropriate interventions in this scenario. Clamping the tube can lead to a dangerous buildup of pressure, while replacing the chest tube system may not be necessary if the issue can be resolved by simply tightening the connections. Continuing to monitor the chest tube without taking corrective action may lead to complications associated with the air leak.

Correct Answer: A

Rationale: The correct answer is A, Albuterol 3 ml via nebulizer. Albuterol is the first-line medication for wheezing due to its rapid bronchodilatory effects. Choice B, Cromolyn, is used more for preventing allergic reactions rather than acute relief of wheezing. Choice C, Methylprednisolone, is a steroid used for its anti-inflammatory effects and is not the initial choice for acute relief of wheezing. Choice D, Aminophylline, is a bronchodilator but is not the first-line treatment for wheezing due to allergic reactions.

Correct Answer: A

Rationale: The correct manifestations of increased intracranial pressure (IICP) include restlessness, confusion, and irritability. These symptoms are a result of the brain being under pressure inside the skull. Severe nausea and vomiting (Choice B) are more commonly associated with increased intracranial pressure in children. Elevated blood pressure and bradycardia (Choice C) are not typical manifestations of increased intracranial pressure; instead, hypertension and bradycardia may be seen in Cushing's reflex, which is a late sign of increased IICP. Decreased heart rate and altered pupil response (Choice D) are also not primary manifestations of increased intracranial pressure, although altered pupil response, like a non-reactive or dilated pupil, can be seen in some cases.

Correct Answer: A

Rationale: The correct answer is A: CD4 T-cell count 180 cells/mm3. Monitoring the CD4 T-cell count is crucial in patients with HIV to assess the status of their immune system. A CD4 count of 180 cells/mm3 indicates severe immunocompromise and a high risk of opportunistic infections. This value is used to guide treatment decisions and assess the need for prophylaxis against specific infections. Choices B, C, and D are incorrect because monitoring white blood cell count, potassium levels, and hemoglobin levels, although important in HIV patients, are not as crucial as monitoring the CD4 T-cell count for assessing immune function and disease progression.
