The student nurse knows that a prescription requires which of the following information?
Method of administration, controlled substance schedule, identification.
Signature of prescriber, dose of drug, drug name.
Method of administration, dose of drug, drug name, signature of prescriber.
Controlled substance schedule, identification, drug name.
The Correct Answer is C
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 normocephalic skull indicates a normal head size and shape, not increased intracranial pressure. Increased intracranial pressure typically manifests with symptoms like headache, altered mental status, and papilledema, and may or may not involve changes in head circumference depending on the patient's age and the chronicity of the pressure increase.
Choice B rationale
"Normocephalic" is a clinical term indicating that the patient's head is of a normal size and shape, appearing symmetrical and proportionally related to the rest of the body. This finding suggests the absence of conditions like microcephaly (abnormally small head) or macrocephaly (abnormally large head), reflecting healthy cranial development and morphology.
Choice C rationale
An abnormally large head is termed macrocephaly, which is distinctly different from normocephalic. Macrocephaly can be indicative of various underlying conditions, including hydrocephalus, genetic disorders, or brain tumors, leading to an enlarged skull circumference that deviates significantly from age and gender norms.
Choice D rationale
An abnormally small head is known as microcephaly, which is the opposite of normocephalic. Microcephaly is often associated with impaired brain development and can result from genetic factors, infections during pregnancy, or other congenital conditions, leading to a head circumference significantly below the expected range. .
Correct Answer is D
Explanation
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.
