What is the appropriate medication dosage for the patient as needed?

Choice A rationale:

Loosening the tape gently by pressing the skin away from it is an important step in changing a burn dressing. However, it is not the first intervention that should be performed. This is because removing the tape can be painful, and it is important to ensure that the patient is adequately pain-free before proceeding.

Choice B rationale:

Observing the wound bed for the presence of granulation tissue is also an important part of burn care. Granulation tissue is a sign of healing, and its presence indicates that the wound is progressing as expected. However, this assessment is not the first priority when changing a dressing. Pain management should always be addressed first.

Choice D rationale:

Gently irrigating the wound using sterile normal saline is another important step in burn care. Irrigation helps to cleanse the wound and remove any debris or dead tissue. However, it should not be performed until the patient's pain has been adequately controlled.

Choice C rationale:

Administering pain medication 30 minutes beforehand is the most important first intervention when changing a painful burn dressing. This allows time for the medication to take effect and ensure that the patient is comfortable before the dressing change begins. Pain management is crucial in burn care, as it can help to reduce anxiety, promote healing, and improve patient outcomes.

Choice A rationale:

The dorsal gluteal site (also known as the dorsogluteal site) was previously a common injection site, but it's now not recommended due to several significant risks:

Proximity to the sciatic nerve: The sciatic nerve is the largest nerve in the body, and it runs close to the dorsal gluteal site. Accidental injection into or near the nerve can cause severe pain, nerve damage, and potential paralysis.

Difficulty in locating landmarks: The landmarks for the dorsal gluteal site can be difficult to locate accurately, especially in obese patients or those with decreased muscle mass. This increases the risk of injecting into the wrong area.

Risk of injury to blood vessels: The dorsal gluteal site also has a higher risk of injury to blood vessels, as several large vessels run through the area.

Choice B rationale:

The deltoid muscle is located in the upper arm and is a common site for intramuscular injections, but it has limitations for larger volumes:

Small muscle size: The deltoid muscle is relatively small compared to other IM injection sites. It's generally recommended for smaller volumes of medication (up to 1 mL in adults).

Subcutaneous tissue: The deltoid muscle often has a layer of subcutaneous tissue (fat) that can hinder absorption of medication.

Choice C rationale:

The vastus lateralis muscle is the preferred site for intramuscular injections in adults for several reasons:

Large muscle size: It's a large, thick muscle that can accommodate larger volumes of medication (up to 5 mL in adults). Easy to locate landmarks: The landmarks for the vastus lateralis are easy to identify, even in obese patients.

Few major nerves or blood vessels: It has fewer major nerves or blood vessels in the area, reducing the risk of injury. Pain tolerance: It's generally considered to be a less painful injection site than the deltoid or dorsogluteal sites.

Choice D rationale:

The lateral piriformis muscle is not a recognized or recommended site for intramuscular injections. It's a deep muscle located in the buttocks, and injecting into it would be difficult and potentially dangerous due to its proximity to the sciatic nerve and other important structures.
