A client you are assigned is experiencing arrhythmia. What sign is the client exhibiting?
Heart rate is less than expected reference range.
Irregular heart rate.
Respiratory rate is less than expected range.
Decrease in blood pressure that occurs upon standing, especially from a lying or sitting position.
The Correct Answer is B
Choice A reason: A heart rate below normal (e.g., <60 bpm) indicates bradycardia, not necessarily arrhythmia, which is characterized by irregular rhythm. Irregular heart rate defines arrhythmia. Assuming low rate risks misdiagnosis, potentially missing treatments like antiarrhythmics, critical for stabilizing rhythm and preventing complications in arrhythmic patients.
Choice B reason: Irregular heart rate is the hallmark of arrhythmia, reflecting disrupted electrical conduction (e.g., atrial fibrillation). This sign, detected via pulse or ECG, guides diagnosis and treatment like anticoagulants or cardioversion. Accurate identification ensures timely intervention, critical for preventing stroke or heart failure in patients with cardiac rhythm disturbances.
Choice C reason: Low respiratory rate is unrelated to arrhythmia, which affects heart rhythm, not breathing. Irregular heart rate is the key sign. Assuming respiratory rate misdirects focus, risking neglect of cardiac monitoring or treatment, potentially delaying management of arrhythmia and increasing risks of thromboembolism or hemodynamic instability.
Choice D reason: Decreased blood pressure upon standing (orthostatic hypotension) is unrelated to arrhythmia, which involves irregular heart rhythm. Misidentifying this risks overlooking cardiac signs like irregular pulse, delaying ECG or antiarrhythmic therapy, critical for managing arrhythmia and preventing complications like syncope or heart failure in affected patients.

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.
Correct Answer is C
Explanation
Choice A reason: This open-ended question prompts a detailed description of seizure-related feelings, encouraging subjective narrative responses. It requires the patient to elaborate on sensory or emotional experiences, which is not conducive to a yes/no or specific answer, making it unsuitable as a closed-ended question.
Choice B reason: Asking about symptoms before a urinary tract infection is open-ended, inviting a broad range of responses about various symptoms. It seeks detailed patient input, not a concise or specific answer, which contrasts with the structure of closed-ended questions that limit response scope.
Choice C reason: Asking when the first stroke occurred is closed-ended, expecting a specific, concise answer, such as a date or time frame. It limits the response to factual data, fitting the definition of a closed-ended question used in medical assessments to gather precise historical information.
Choice D reason: This question about past work is open-ended, prompting a detailed recount of occupational history. It encourages expansive answers, not a single, definitive response, making it inappropriate as a closed-ended question, which seeks focused, limited information in clinical settings.
