Review of System (ROS):

1. General: Patient is a 16-year-old female with sudden onset of problem swallowing and burning in her throat, feeling excessively warm and light-headed, with intermittent blurred vision and headache pain in the forehead area.
2. Respiratory: Gradual worsening hoarseness with post nasal drip a couple of days ago.
3. Cardiovascular: Elevated temperature, blood pressure, and heart rate.
4. ENT (Ear, Nose, and Throat): Red oral pharynx with enlarged glands.
5. Neurological: Blurred vision and headache pain.

Probable Problem: The probable problem for this patient is acute pharyngitis, likely caused by a viral infection such as the common cold or influenza. The symptoms of sore throat, difficulty swallowing, hoarseness, and postnasal drip are consistent with acute pharyngitis. The patient's elevated temperature, blood pressure, and heart rate indicate a systemic inflammatory response to the infection.

Pathophysiology: Acute pharyngitis is inflammation of the pharynx, typically caused by a viral infection. The inflammatory response leads to redness and swelling of the oral pharynx, enlarged glands, and symptoms such as sore throat, difficulty swallowing, and hoarseness. The systemic inflammatory response causes the patient to feel warm, light-headed, and experience blurred vision and headache pain.

Nursing Interventions:
1. Provide supportive care, including rest, hydration, and pain relief.
2. Educate the patient on proper hand hygiene and respiratory etiquette to prevent the spread of the viral infection.
3. Monitor the patient's vital signs and symptoms for any signs of deterioration.

Medical Interventions:
1. Consider a rapid strep test or throat swab to rule out bacterial pharyngitis.
2. Prescribe antiviral medications if indicated based on the specific viral cause.
3. Consider corticosteroids for severe symptoms or to reduce inflammation.
