In addition to the forearm, which of these sites are commonly used for the administration of an intradermal injection?
Abdomen, 2-in. from umbilicus.
Anterior thigh.
Posterior upper arm.
Upper chest.
The Correct Answer is D
Choice A rationale
The abdomen, specifically 2 inches from the umbilicus, is a common site for subcutaneous injections due to the presence of ample adipose tissue, which allows for slower absorption of medications like insulin or heparin. Intradermal injections require a site with a thin epidermis and minimal subcutaneous tissue to ensure the medication remains within the dermal layer, making the abdomen unsuitable.
Choice B rationale
The anterior thigh is a common site for intramuscular injections, particularly in infants, due to the large muscle mass (vastus lateralis). While it can be used for subcutaneous injections, its muscularity and varying skin thickness make it less ideal for the precise shallow angle required for an intradermal injection, where the goal is to deposit the medication into the dermis.
Choice C rationale
The posterior upper arm, specifically the triceps area, is frequently utilized for subcutaneous injections, such as insulin or certain vaccines, because it offers sufficient subcutaneous tissue. However, similar to the anterior thigh, its anatomical characteristics with thicker skin and subcutaneous fat layers make it less optimal for the very superficial intradermal injection technique.
Choice D rationale
The upper chest, particularly below the clavicle and above the breasts, is an appropriate site for intradermal injections. This area, along with the inner forearm and upper back, has a thin epidermis and less subcutaneous tissue, which facilitates the proper placement of the medication within the dermis, allowing for the formation of a visible wheal, a key indicator of a successful intradermal injection.

Correct Answer is C
Explanation
Choice A rationale
While method of administration is crucial, controlled substance schedule and identification are not universally required on every prescription. The core components for safe and effective medication administration are paramount for all prescriptions.
Choice B rationale
This choice omits the method of administration, which is vital for safe and effective drug delivery. Without this information, there is a risk of administering the medication incorrectly, potentially leading to adverse effects or lack of therapeutic benefit.
Choice C rationale
A complete prescription scientifically requires the drug name for identification, the dose to ensure therapeutic effect and prevent toxicity, the method of administration for correct delivery route, and the prescriber's signature for legal authorization and accountability.
Choice D rationale
Controlled substance schedules are specific to certain medications and identification is not a standard universal requirement on all prescriptions. The core components for general medication administration are the drug name, dose, method, and prescriber signature.
Correct Answer is B
Explanation
Choice A rationale
A stat medication order signifies an immediate and urgent administration of the drug, typically within 30 minutes of the order. This is for critical situations where delay could significantly impact patient outcome, requiring prompt action rather than nurse's judgment for necessity.
Choice B rationale
A PRN (pro re nata) medication order means "as needed.”. This type of order grants the nurse professional discretion to administer the medication based on their assessment of the patient's condition and the specific criteria outlined in the order, such as pain level or fever.
Choice C rationale
A scheduled medication order involves administering the drug at regularly prescribed intervals, such as every 8 hours or once daily. The timing is predetermined, and the nurse's primary role is adherence to the schedule, with less independent judgment regarding administration necessity.
Choice D rationale
A single-dose order is for a medication to be given only once at a specific time. This is often used for preoperative medications or diagnostic procedures. Like scheduled orders, the timing is set, and the nurse's judgment about the necessity of administration is not the primary factor.
