Which cranial nerve is responsible for the sense of smell?
V – Trigeminal.
II – Optic.
I – Olfactory.
VIII – Vestibulocochlear.
The Correct Answer is C
Choice A reason: The trigeminal nerve (V) controls facial sensation and chewing, not smell, which is governed by the olfactory nerve (I). Misidentifying this risks incorrect neurological assessment, potentially missing olfactory deficits indicating brain injury or tumors, critical for accurate diagnosis and management in patients with sensory complaints.
Choice B reason: The optic nerve (II) governs vision, not smell, which is the olfactory nerve’s function (I). Assuming optic involvement misguides cranial nerve assessment, risking oversight of olfactory dysfunction, which may signal neurological conditions like Parkinson’s or trauma, requiring targeted evaluation and intervention in clinical practice.
Choice C reason: The olfactory nerve (I) is responsible for the sense of smell, transmitting sensory input from the nasal mucosa to the brain. Accurate identification ensures proper neurological assessment, detecting deficits that may indicate trauma, tumors, or neurodegenerative diseases, guiding diagnosis and treatment in patients with smell-related complaints.
Choice D reason: The vestibulocochlear nerve (VIII) controls hearing and balance, not smell, which is the olfactory nerve’s role (I). Misidentifying this risks incorrect assessment, potentially overlooking olfactory issues signaling neurological pathology, delaying diagnosis and management critical for addressing sensory deficits in clinical neurological evaluations.

Correct Answer is A
Explanation
Choice A reason: Using an interpreter enhances client satisfaction by ensuring clear communication, respecting language needs, and fostering trust. This improves patient engagement and care quality, critical for positive healthcare experiences. Accurate language support prevents misunderstandings, ensuring clients feel heard and valued, especially in diverse populations with language barriers.
Choice B reason: Interpreters increase initial costs due to service fees, not decrease them. The focus is on communication accuracy and satisfaction, not cost reduction. Assuming cost savings misaligns with interpreter use, risking neglect of language needs, which could lead to errors or dissatisfaction in patients with limited English proficiency.
Choice C reason: Interpreters increase communication accuracy by bridging language gaps, ensuring precise health history collection and reducing errors in diagnosis or treatment. This is critical for safe, effective care in non-English-speaking patients, preventing misinterpretations that could compromise health outcomes and patient safety in clinical settings.
Choice D reason: While interpreters may indirectly support self-esteem by respecting language needs, this is not a primary reason for their use. Accuracy and satisfaction are key. Assuming self-esteem is the focus risks prioritizing emotional over practical needs, potentially neglecting communication accuracy critical for effective health history and care planning.
Correct Answer is B
Explanation
Choice A reason: Blood pressure 127/65 and HR 68 are within normal ranges (BP <130/<80, HR 60-100), expected in healthy cardiovascular assessments. Trace edema is abnormal, suggesting fluid retention. Assuming this is unexpected risks overlooking normal findings, diverting focus from issues like edema needing evaluation in cardiovascular assessments.
Choice B reason: Trace edema in bilateral lower ankles is an unexpected finding, indicating potential fluid overload, heart failure, or venous insufficiency. Unlike normal vitals or pulses, edema requires investigation and reporting. Recognizing this ensures timely diagnosis and management, critical for preventing progression of underlying cardiovascular or systemic conditions in affected patients.
Choice C reason: Capillary refill within 2 seconds is normal, indicating adequate peripheral perfusion, expected in cardiovascular assessments. Edema is the abnormal finding. Assuming refill is unexpected risks misprioritizing normal findings, neglecting issues like edema that signal potential heart or venous issues, critical for accurate cardiovascular evaluation and care.
Choice D reason: Equal apical and radial pulses are expected, reflecting synchronized cardiac output, normal in cardiovascular assessments. Trace edema is abnormal, suggesting fluid issues. Assuming pulses are unexpected risks overlooking normal findings, diverting attention from edema, critical for identifying and managing underlying cardiovascular conditions in clinical practice.
