All of the followings are parts of a needle except? A. Plunger B. Bevel C. Hilt D. Hub 79) The smallest filter that can be used to withdraw medications is a A. Filter straw B. Filter needle C. 5 micrometer filter D. 0.22 micrometer filter
The Correct Answer and Explanation is :
The correct answers for the two questions are as follows:
- All of the following are parts of a needle except:
- C. Hilt
- The smallest filter that can be used to withdraw medications is:
- D. 0.22 micrometer filter
Explanation:
- Parts of a Needle:
- A needle consists of several key parts, including:
- Plunger: This is part of a syringe, which is used to draw or push medication through the needle. The plunger works by creating pressure within the barrel of the syringe to push the liquid out.
- Bevel: The bevel is the angled tip of the needle that helps make a clean puncture when injecting or withdrawing fluids. It ensures that the needle enters the skin with less trauma and discomfort.
- Hub: The hub is the part that connects the needle to the syringe. It is located at the opposite end of the needle, where it is securely attached to the syringe to ensure stability during injections or withdrawals.
- Filter for Medication Withdrawal:
- Filters are used in needles or syringes to remove particulates and contaminants from medications, which is essential for patient safety.
- Filter straw and filter needle are types of filters, but their use depends on the size and application.
- 5 micrometer filter is larger than needed for most medication withdrawals, as it would not effectively remove all potentially harmful particles.
- 0.22 micrometer filter is a standard, highly effective filter size for withdrawing medications. It can filter out particles as small as bacteria, which are typically in the 0.2 to 2 micrometer range, ensuring that the medication is free of contaminants and safe for injection.
