Explanation

A. Bilateral breath sounds clear and present throughout at 1600 are normal findings and do not require immediate follow-up.
B. The temperature at both 1600 (37.6°C) and 1630 (37.5°C) is slightly elevated but not critically high. It does not require immediate follow-up unless it worsens significantly or is accompanied by other concerning symptoms.
