What is a diagnostic tool used to evaluate the electrical conduction of the heart and provides information on the heart rate and heart rhythm?
Stethoscope
Blood pressure cuff and monitor
Electrocardiogram
Doppler
The Correct Answer is C
Choice A reason: A stethoscope assesses heart sounds, detecting murmurs or irregular beats, but does not measure electrical conduction. It provides auditory data on valve function, not heart rate or rhythm via electrical activity. Electrocardiograms are required for detailed analysis of cardiac electrical patterns, making this choice incorrect.
Choice B reason: A blood pressure cuff measures arterial pressure, reflecting cardiovascular workload, but not electrical conduction. It provides systolic and diastolic values, not heart rhythm or rate data. Electrical activity assessment requires tools like electrocardiograms, rendering this choice irrelevant for the described diagnostic purpose.
Choice C reason: An electrocardiogram (ECG) records the heart’s electrical activity, mapping conduction pathways to assess heart rate and rhythm. It detects arrhythmias, ischemia, or conduction delays by analyzing waveforms like P, QRS, and T, making it the precise tool for evaluating cardiac electrical function, as required by the question.
Choice D reason: Doppler ultrasound evaluates blood flow velocity, used in vascular or fetal assessments, but does not measure cardiac electrical conduction. It lacks the capability to assess heart rate or rhythm through electrical signals, unlike an electrocardiogram, making it an incorrect choice for this diagnostic purpose.

Correct Answer is A
Explanation
Choice A reason: Taking retirement checks and limiting access to funds is financial abuse, exploiting the patient’s resources. This violates elder rights, requiring reporting and social service intervention. Accurate identification ensures protection, critical for restoring financial autonomy and preventing further exploitation, enhancing safety and well-being in vulnerable elderly patients.
Choice B reason: Emotional abuse involves psychological harm like humiliation, not directly indicated by taking retirement funds, which is financial abuse. Assuming emotional risks misclassification, delaying financial protection measures, critical for addressing exploitation and ensuring the patient’s economic security, essential for elder abuse prevention and support.
Choice C reason: Neglect involves failure to provide care, like food or medical needs, not specifically taking funds, which is financial abuse. Misidentifying as neglect risks overlooking financial exploitation, delaying interventions like legal guardianship, critical for protecting the patient’s assets and ensuring safety in elder care settings.
Choice D reason: Physical abuse involves bodily harm, not indicated by financial exploitation like taking retirement checks. Assuming physical risks missing financial abuse, delaying reporting or social services, critical for stopping exploitation, restoring financial control, and ensuring the patient’s safety and dignity in elder abuse scenarios.
Correct Answer is D
Explanation
Choice A reason: Smoking history is relevant for vascular or lung issues but not directly for unilateral arm edema, which suggests localized causes like lymphedema. Breast surgery history is more pertinent. Assuming smoking is key risks missing lymphatic causes, delaying diagnosis and management of edema in affected patients.
Choice B reason: Left arm edema may indicate lymphedema from breast surgery, like mastectomy, which disrupts lymphatic drainage. Asking about surgery history is critical to identify causes, guiding interventions like compression therapy. This targeted question ensures accurate diagnosis, preventing complications like chronic swelling or infection in patients with post-surgical edema.
Choice C reason: Recent weight gain may cause generalized edema but is less likely for unilateral arm edema, which points to localized issues like post-surgical lymphedema. Assuming weight gain is key risks overlooking specific causes, delaying targeted treatments critical for managing localized edema and improving patient comfort and function.
Choice D reason: Extra nipples (supernumerary nipples) are anatomical variants, unrelated to arm edema, which likely stems from lymphatic or vascular issues. Assuming this is relevant misdirects assessment, risking neglect of surgical history, critical for diagnosing lymphedema and implementing appropriate interventions like lymphatic drainage or compression.
