A mother called the pediatrician's office, reporting that her infant son had a temperature of 102.6

F. The nurse is to record the information as a Celsius temperature.

What should the nurse write down as the temperature reported by the mother?

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.

Choice A rationale

Cranial nerve I (olfactory) is responsible for smell, and cranial nerve II (optic) is responsible for vision. Cranial nerve V (trigeminal) is involved in facial sensation and mastication. These nerves are not primarily involved in controlling the extrinsic eye muscles responsible for eye movement.

Choice B rationale

Cranial nerve III (oculomotor) innervates the superior, inferior, and medial recti, and the inferior oblique muscles, and controls eyelid elevation. Cranial nerve IV (trochlear) innervates the superior oblique muscle. Cranial nerve VI (abducens) innervates the lateral rectus muscle. Together, these three cranial nerves precisely coordinate all six extraocular muscles for conjugate gaze.

Choice C rationale

While cranial nerve III (oculomotor) is correctly identified, cranial nerve V (trigeminal) and cranial nerve XI (accessory) are not primarily involved in eye movement. Cranial nerve V is involved in facial sensation and mastication, and cranial nerve XI innervates the sternocleidomastoid and trapezius muscles for head and shoulder movement.

Choice D rationale

Cranial nerve II (optic) is responsible for vision, transmitting visual information from the retina to the brain. Cranial nerve V (trigeminal) is involved in facial sensation and chewing. Cranial nerve VI (abducens) is correctly identified as innervating the lateral rectus, but the other two nerves listed do not control the majority of eye movements.
