Normal oral temperature of 98.6°F is equivalent to 37.0°C. This conversion is based on the formula for converting Fahrenheit to Celsius: C=(F−32)×59\text{C} = (\text{F} - 32) \times\frac{5}{9}C=(F−32)×95​. Maintaining accurate temperature readings is important for diagnosing and monitoring various medical conditions.

Aglucose tolerance test (GTT)is used to evaluate how well the body processes glucose, which is crucial for diagnosing conditions related to sugar metabolism, such as diabetes and insulin resistance. During the test, a patient consumes a glucose-rich beverage, and blood samples are taken at intervals to measure blood glucose levels. The primary purpose is to assess the body's ability to metabolize sugar.

Thegaugeof a needle refers to its diameter, with a lower gauge number indicating a larger diameter. Therefore, a19 gauge needlehas the widest lumen among the options given. It is commonly used for rapid blood transfusions or for drawing viscous fluids.

21 gauge: Smaller lumen than 19 gauge.

22 gauge: Smaller lumen than 21 gauge.

26 gauge: Smallest lumen of the options listed.

The best way to take a respiratory rate is bywatching the patient's chest rise and fall while appearing to take the pulse. This method allows for an accurate count of breaths per minute without making the patient conscious of their breathing, which could alter the rate. This approach is subtle and ensures that the patient remains relaxed.Reference:Nationally Registered Certified Medical Assistant study materials, clinical examination techniques.
