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: Medication reconciliation involves compiling a complete, accurate list of current medications, including prescriptions, supplements, herbals, and OTC drugs, to ensure safe transitions across care settings. This prevents errors like omissions or duplications, critical for patient safety, guiding accurate prescribing and reducing adverse drug events in clinical practice.
Choice B reason: Listing medications prescribed at discharge is part of discharge planning, not full medication reconciliation, which includes all current medications across settings. This narrow definition risks missing ongoing therapies, leading to errors like discontinued drugs, compromising safety and continuity of care during transitions in healthcare settings.
Choice C reason: Listing medication allergies is part of allergy documentation, not medication reconciliation, which focuses on current medications. Confusing these risks overlooking active prescriptions, leading to potential drug errors or interactions. Reconciliation ensures a comprehensive medication profile, critical for safe prescribing and patient care across healthcare transitions.
Choice D reason: Obtaining medication interactions is a pharmacist’s analysis, not medication reconciliation, which compiles a current medication list. Assuming this misaligns with reconciliation’s purpose, risking incomplete profiles and errors like missed doses. Reconciliation ensures accurate medication records, essential for preventing adverse events and supporting safe care transitions.
Correct Answer is C
Explanation
Choice A reason: Head protrusions are not expected in older adults; they may indicate abnormal growths or trauma, requiring investigation. Thinning hair is a normal aging change. Assuming protrusions are expected risks missing serious conditions like tumors, delaying diagnosis and treatment critical for ensuring safety in elderly patients.
Choice B reason: Asymmetry of facial features is not a normal aging variation; it may suggest stroke or Bell’s palsy, needing urgent evaluation. Thinning hair is expected due to hormonal changes. Assuming asymmetry is normal risks overlooking neurological issues, delaying interventions critical for older adults’ health and functional outcomes.
Choice C reason: Thinning hair is an expected aging variation, resulting from reduced hair follicle activity and hormonal changes in older adults. Unlike vertigo or asymmetry, it’s benign and doesn’t require intervention unless cosmetic. Recognizing this ensures accurate assessment, focusing on abnormal findings like vertigo that need medical attention in elderly patients.
Choice D reason: Vertigo is not an expected aging variation; it may indicate inner ear disorders or neurological issues, requiring evaluation. Thinning hair is a normal change. Assuming vertigo is expected risks delaying diagnosis of treatable conditions like BPPV, compromising safety and quality of life in older adults.
