A patient is admitted to the hospital with facial trauma secondary to a motor vehicle accident. The advanced practice registered nurse (APRN) strokes the cornea of each eye with a cotton wisp to check for reflex blinking. What is the name of this reflex and what is the cranial nerve being assessed?
Cardinal reflex; CN IV &V
Corneal reflex; CNV &VII
Oculocephalic reflex; CN III, VI, &VIII
Oculovestibular reflex; CN III, VII, &VIII
The Correct Answer is B
A. Cardinal reflex; CN IV & V is incorrect because there is no reflex termed “cardinal reflex” in clinical neuroassessment. CN IV (trochlear) controls superior oblique eye movement and is not involved in blinking. CN V (trigeminal) is partially involved in corneal sensation, but the reflex is paired with CN VII.
B. Corneal reflex; CN V & VII is correct. The corneal reflex is elicited by gently touching the cornea with a cotton wisp, which should trigger bilateral blinking. This reflex assesses CN V (trigeminal nerve, ophthalmic branch) for sensory input from the cornea and CN VII (facial nerve) for motor output causing the orbicularis oculi muscle to blink. Testing the corneal reflex is particularly important in facial trauma, altered consciousness, or neurological deficits.
C. Oculocephalic reflex; CN III, VI, & VIII is incorrect because this is the “doll’s eyes” reflex, used to assess brainstem function in unconscious patients by turning the head and observing eye movement. It does not involve corneal stimulation.
D. Oculovestibular reflex; CN III, VII, & VIII is incorrect because this refers to the caloric test (cold water in the ear canal to observe eye movements) to evaluate brainstem integrity. It is unrelated to corneal stimulation.

Correct Answer is D
Explanation
A. Capture the patient's personality and interests, sources of support, strengths, and fears is incorrect because this describes aspects of the social history and psychosocial assessment, not the Review of Systems (ROS).
B. Obtain objective information regarding the patient's various body systems is incorrect because the ROS is based on subjective, patient-reported symptoms, not objective findings. Objective data is collected during the physical examination and diagnostic testing.
C. Provide a complete and chronologic account of the problems prompting the patient to seek care is incorrect because this describes the history of present illness (HPI), which focuses on the timeline and details of the chief complaint.
D. Uncover problems the patient has overlooked, particularly in areas unrelated to the present illness is correct because the Review of Systems (ROS) is a systematic set of questions covering all body systems to identify additional symptoms that the patient may not have mentioned. It helps detect hidden or unrelated issues, ensuring a comprehensive assessment.
Correct Answer is D
Explanation
A. Chief Complaint/Concern is incorrect because this section is reserved for the primary reason the patient is seeking care, typically expressed in their own words. For example, a patient may report, “I have chest discomfort” or “I am having difficulty breathing.” The statement provided lists denied symptoms, not the patient’s presenting complaint, so it does not belong under chief complaint.
B. Past Medical History is incorrect because this section documents the patient’s previous medical diagnoses, chronic illnesses, hospitalizations, surgeries, and ongoing treatments. The provided information does not describe past illnesses or interventions but rather current symptom assessment, making it unrelated to past medical history.
C. Social History is incorrect because it includes details about lifestyle factors, habits, occupational exposures, living situation, and social support systems. Examples include tobacco or alcohol use, exercise routines, employment, and household composition. Symptom denial or presence is not part of social history.
D. Review of Systems (ROS) is correct because it is a systematic inventory of patient-reported symptoms organized by body system. The APRN or clinician asks about symptoms such as chest pain, palpitations, shortness of breath, orthopnea, and paroxysmal nocturnal dyspnea, and the patient’s denials are documented to indicate the absence of these symptoms. ROS allows the healthcare provider to identify both present and absent symptoms, providing a comprehensive overview of the patient’s health status and highlighting areas that may need further evaluation or monitoring.
