0.75 mL
To achieve a dose of 1.5 mg using a 2 mg/mL concentration, the nurse calculates the volume needed by dividing the desired dose by the concentration, resulting in 0.75 mL.
A: 1 mL This volume would deliver 2 mg, exceeding the prescribed dose and potentially leading to an overdose scenario.
B: 0.5 mL Administering this amount would only provide 1 mg, insufficient to meet the required dosage for effective pain management.
C: 1.5 mL This dosage corresponds to 3 mg based on the concentration, which is more than the patient requires and poses a risk of adverse effects.

The nurse is giving an intradermal (ID) injection and will choose which syringe for this injection?
Correct!
Incorrect
The correct answer is: B
Rationale
B: The 1 mL syringe with a small gauge needle is ideal for intradermal injections, allowing precise delivery of medication within the skin layers, which is essential for accurate testing and vaccination purposes.
A: interderm_1.PNG This syringe may not have the appropriate gauge size for intradermal injections, potentially leading to inaccurate delivery or insufficient medication absorption into the dermal layer.
C: interderm_3.PNG Featuring a larger volume capacity, this syringe is unsuitable for intradermal injections, where minimal medication amounts are required to achieve effective results without causing tissue damage.
D: interderm_4.PNG This syringe likely has an inappropriate needle length or gauge, which can compromise the technique of intradermal administration, leading to suboptimal results or adverse effects.
