He has no trouble swallowing water, broth, or gelatin. The patient has no pain, cough, or nasal regurgitation after swallowing. He frequently plays football and takes ibuprofen to relieve aches and pains. He has seasonal allergies and takes antihistamines during the spring. Temperature is 37.3 C (99.1 F) , blood pressure is 125/78 mm Hg, pulse is 76/min, and respirations are 12/min. BMI is 28 kg/m2. Heart and lung sounds are unremarkable.
