You are the nurse performing a nose and mouth assessment.
Which of the following assessment techniques stimulates cranial nerve XII (hypoglossal)?
Ask the client to stick out their tongue and move it from side to side, then up and down.
Ask the client to stick out their tongue.
Ask the client to cover one eye and read a note card.
Have the patient smile, frown, and puff their cheeks.
The Correct Answer is A
Choice A rationale
Asking the client to stick out their tongue and move it from side to side, then up and down, directly assesses the function of the hypoglossal nerve (cranial nerve XII). This nerve innervates the intrinsic and extrinsic muscles of the tongue, controlling its movement, which is essential for speech and swallowing, thereby evaluating its motor integrity.
Choice B rationale
Asking the client to stick out their tongue primarily assesses general tongue protrusion, but does not provide as comprehensive an assessment of hypoglossal nerve function as evaluating its full range of motion. Unilateral weakness or deviation, which is indicative of nerve damage, is better observed with side-to-side and up-and-down movements.
Choice C rationale
Asking the client to cover one eye and read a note card assesses visual acuity and the function of the optic nerve (cranial nerve II). This technique evaluates the eye's ability to perceive details and is unrelated to the motor function of the tongue or the hypoglossal nerve.
Choice D rationale
Having the patient smile, frown, and puff their cheeks primarily assesses the facial nerve (cranial nerve VII). This nerve controls the muscles of facial expression, including those involved in smiling, frowning, and puffing out the cheeks, and is distinct from the hypoglossal nerve's role in tongue movement.

Correct Answer is D
Explanation
Choice A rationale
An absent pulse (0) indicates no palpable pulsation, often due to an occlusion or severe vasoconstriction. This signifies a complete lack of blood flow through the vessel, requiring immediate medical attention to prevent tissue ischemia and necrosis.
Choice B rationale
A bounding pulse (4+) is characterized by a strong, easily palpable pulsation that is not easily obliterated by pressure. This can indicate conditions like fluid overload, hypertension, or hyperkinetic states, reflecting increased stroke volume or decreased peripheral resistance.
Choice C rationale
A weak pulse (1+) is characterized by a faint, barely palpable pulsation that is easily obliterated by pressure. This can be indicative of decreased stroke volume, hypovolemia, or peripheral artery disease, signifying reduced blood flow and perfusion.
Choice D rationale
A normal pulse (2+) is characterized by a readily palpable pulsation that is easily discernible and not easily obliterated by pressure. This finding indicates adequate cardiac output and peripheral perfusion, signifying healthy cardiovascular function within normal physiological parameters.
Correct Answer is B
Explanation
Choice A rationale
The head-to-toe format does not exclude unnecessary body systems; rather, it aims to systematically include all major body systems to ensure a comprehensive assessment. Excluding systems could lead to missed findings and an incomplete understanding of the patient's health status. A thorough examination requires a complete survey, even if initial symptoms point to a specific area, to identify any related or unrelated issues.
Choice B rationale
A head-to-toe approach provides a structured and systematic method for examining all body systems. This ensures that no area is overlooked, promoting a comprehensive data collection process. It allows for a logical flow, minimizing omissions and facilitating the identification of interconnections between different bodily functions. This organization enhances efficiency and thoroughness in clinical assessment.
Choice C rationale
The head-to-toe approach does not mandate that painful procedures be done first. In fact, best practice dictates that painful or uncomfortable assessments should generally be deferred until the end of the examination to maintain patient cooperation and trust. Starting with non-painful assessments allows the patient to acclimate and reduces anxiety, improving the overall quality of the examination.
Choice D rationale
A head-to-toe assessment does not reduce time by examining only one side of the body. A comprehensive physical examination requires bilateral assessment of most structures and systems to identify asymmetries or unilateral abnormalities. Limiting the examination to one side would provide an incomplete and potentially misleading clinical picture. Full evaluation ensures all relevant data are collected.
