Correct Answer is A
Explanation
Answer: A
Rationale:
A) A client who has hemorrhoids: An oral temperature is appropriate for this client as there are no contraindications for using the oral route. Hemorrhoids do not affect the accuracy or safety of oral temperature measurement.
B) A client who had recent oral surgery: Oral temperature measurement should be avoided for this client as it may cause discomfort or disrupt the healing process. Alternative routes, such as tympanic or axillary, are more appropriate.
C) A client who has a coagulation disorder: Oral temperature measurement might be risky in clients with coagulation disorders due to the potential for trauma or bleeding from the oral mucosa. A non-invasive method is preferable for safety.
D) A client who is drinking ice water: Drinking ice water can temporarily lower the temperature in the oral cavity, leading to inaccurate readings. The nurse should wait 15–30 minutes before measuring an oral temperature.
