Which technique will the nurse use to assess the patient's olfactory nerve?
Ask the patient to turn his head side-to-side against resistance.
Ask the patient to stick out the tongue and move it side-to-side from midline.
Ask the patient to read the smallest set of letters on a Snellen eye chart.
Ask the patient to identify the smell of vanilla and orange peel.
The Correct Answer is D
Choice A rationale
Asking the patient to turn their head side-to-side against resistance assesses the accessory nerve (cranial nerve XI), which innervates the sternocleidomastoid and trapezius muscles. This action tests muscle strength and integrity of the nerve pathways responsible for head and shoulder movement.
Choice B rationale
Asking the patient to stick out the tongue and move it side-to-side from midline assesses the hypoglossal nerve (cranial nerve XII). This nerve is responsible for the motor control of the intrinsic and extrinsic muscles of the tongue, crucial for speech articulation and swallowing.
Choice C rationale
Asking the patient to read the smallest set of letters on a Snellen eye chart assesses visual acuity, primarily testing the optic nerve (cranial nerve II) and the visual pathways. This evaluates the patient's ability to discern details at a distance.
Choice D rationale
Asking the patient to identify the smell of vanilla and orange peel directly assesses the olfactory nerve (cranial nerve I). This nerve is responsible for the sense of smell, and presenting distinct, non-irritating odors allows for the evaluation of its function and patency.

Correct Answer is D
Explanation
Choice A rationale
A 25-gauge 1/2-inch needle with an insulin syringe is typically used for subcutaneous injections, especially for insulin administration. Insulin syringes are calibrated in units, which is not appropriate for general medication administration requiring volume measurement for intradermal injections.
Choice B rationale
A 23-gauge 1-inch needle with a 3 mL syringe is commonly used for intramuscular injections. The 23-gauge needle is too large and the 1-inch length is too long for the superficial nature of an intradermal injection, which only penetrates the epidermis and a small portion of the dermis.
Choice C rationale
A 21-gauge 1 1/2-inch needle with a 5 mL syringe is typically used for intramuscular injections, especially for viscous medications or larger muscle masses. The needle gauge is too large and the length is excessive for an intradermal injection, which requires a very short, fine needle.
Choice D rationale
A 25-gauge to 27-gauge needle and a 3/8-inch to 5/8-inch length are appropriate for intradermal injections because they are very fine and short, allowing for precise placement within the dermis to create a wheal. Tuberculin syringes are calibrated in hundredths of a milliliter, allowing for accurate measurement of the small volumes (0.01-0.1 mL) typically administered intradermally.
Correct Answer is ["250"]
Explanation
Step 1: Refer to LABEL #2- CEFTRIAXONE. The label indicates that for IM administration, 0.5 g (500 mg) can be reconstituted with 1.8 mL of diluent to yield a concentration of 250 mg/mL.
Step 2: The question asks for the drug dosage after reconstitution for IM administration. The label explicitly states 250 mg/mL. Answer: 250 mg/mL.
