A nurse is reinforcing teaching with a newly licensed nurse about measuring body temperature in clients. The nurse should instruct to obtain an oral temperature in which of the following clients? (Select all that apply.)

A. Hemorrhoids do not affect the ability to obtain an oral temperature, so this route is appropriate. B. Mouth breathing can alter oral temperature readings and make them inaccurate; another route is preferred. C. Recent intake of cold or hot fluids can skew oral temperature measurements, so waiting at least 15–30 minutes or using an alternate route is recommended. D. Oral temperature measurement is safe for clients with coagulation disorders, unlike rectal measurement, which could cause bleeding. E. Oral measurement is contraindicated because inserting a thermometer could cause pain or injury at the surgical site.
