A Z-tract injection is a technique used to administer medication intramuscularly to minimize leakage and irritation of the medication in the subcutaneous tissue. The Z-tract method involves pulling the skin and subcutaneous tissue to one side before inserting the needle into the muscle, injecting the medication, and then releasing the tissue after withdrawing the needle.

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.
