You can be sure you have administered the intradermal injection properly if which occurs?
There is no pain at the site.
There is immediate blood return at the site.
The skin remains flat and turns red at the injection site.
A bleb or wheal occurs immediately.
The Correct Answer is D
Choice A rationale
Absence of pain at the site of an intradermal injection does not confirm proper administration. While minimizing pain is a goal, the primary indicator of correct intradermal placement is the formation of a bleb, which signifies the medication has been correctly deposited within the dermal layer, not subcutaneously.
Choice B rationale
Immediate blood return at the site of an intradermal injection indicates improper technique, specifically penetration into a blood vessel. Intradermal injections are administered into the avascular dermal layer; therefore, aspiration should yield no blood, and blood return necessitates withdrawing and restarting the injection at a new site.
Choice C rationale
Skin remaining flat and turning red at the injection site is not indicative of proper intradermal injection. Redness may occur due to irritation, but a flat appearance suggests the medication was either injected too deeply into the subcutaneous tissue or insufficient volume was administered into the dermal layer to form a bleb.
Choice D rationale
The immediate formation of a bleb or wheal, resembling a small blister, is the definitive sign of a correctly administered intradermal injection. This occurs because the medication is deposited precisely into the superficial dermal layer of the skin, causing a localized elevation as the fluid displaces tissue.

Correct Answer is C
Explanation
Choice A rationale
Directly placing pills in a client's mouth with a gloved hand is generally not recommended as it can be perceived as invasive and may trigger the gag reflex, increasing the risk of aspiration. Client autonomy and active participation in medication administration are promoted for safety and adherence.
Choice B rationale
Tipping pills directly into a client's mouth can be problematic as it does not allow the client to assess the medication, potentially leading to discomfort or aspiration. It also bypasses the client's agency in the medication administration process, which is crucial for safety and compliance.
Choice C rationale
Offering the client the medication in their hand promotes autonomy and allows them to actively participate in the medication administration process. This approach respects client preferences, enhances safety by allowing self-administration, and facilitates the client's ability to examine the medication before ingestion, reducing the risk of errors.
Choice D rationale
Leaving medications unattended on a breakfast tray for later self-administration is a significant safety breach. This practice increases the risk of the medication being taken by another individual, loss or contamination, or incorrect timing of administration, potentially leading to adverse drug events. Direct observation of medication ingestion is essential.
Correct Answer is A
Explanation
Choice A rationale
The vastus lateralis muscle is the preferred intramuscular injection site for infants and children due to its large muscle mass and lack of major nerves or blood vessels, minimizing the risk of injury. This site is easily accessible and provides a safe area for medication absorption in developing musculature.
Choice B rationale
The ventrogluteal site is generally considered safe and effective for intramuscular injections, but it requires precise anatomical landmark identification, which can be challenging in infants and young children, increasing the risk of sciatic nerve injury if landmarks are not accurately identified.
Choice C rationale
The dorsogluteal site is contraindicated for intramuscular injections in infants and children due to the risk of sciatic nerve damage. The sciatic nerve runs through this area, and the muscle mass is not fully developed in younger patients, making it a hazardous site.
Choice D rationale
The deltoid muscle is too small and underdeveloped in infants and young children to safely accommodate intramuscular injections. Its limited muscle mass increases the risk of injury to underlying nerves and blood vessels, and absorption capacity is reduced.
