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 D
Explanation
Choice A reason: Urinary retention involves inability to empty the bladder, causing overflow, not involuntary leakage during laughing or sneezing, which indicates stress incontinence. Misdiagnosing retention risks inappropriate treatments like catheterization, delaying pelvic exercises or medications, critical for managing stress incontinence and improving quality of life in affected patients.
Choice B reason: Constipation affects bowel function, not urinary control, unlike stress incontinence, where leakage occurs during physical stress like sneezing. Assuming constipation misguides diagnosis, risking neglect of urinary interventions like Kegel exercises, essential for strengthening pelvic muscles and preventing incontinence-related limitations in daily activities.
Choice C reason: Hiatal hernia causes gastrointestinal symptoms like reflux, not urinary leakage during activities, which defines stress incontinence. Misdiagnosing hernia risks overlooking pelvic floor issues, delaying treatments like biofeedback, critical for managing incontinence, reducing activity limitations, and improving comfort in patients with stress-related urine loss.
Choice D reason: Stress incontinence involves involuntary urine leakage during activities like laughing or sneezing due to weakened pelvic floor muscles, common in women. Recognizing this guides interventions like pelvic exercises or surgery, critical for reducing activity limitations, improving quality of life, and addressing physical and emotional impacts in affected patients.
Correct Answer is B
Explanation
Choice A reason: Dysesthesia refers to abnormal sensations, often painful, like burning or aching, due to nerve damage. While related to sensory nerve dysfunction, it does not specifically describe the pins and needles sensation, which is better characterized by paresthesia, making this term less precise for the patient’s complaint.
Choice B reason: Paresthesia describes abnormal sensations like pins and needles, typically from nerve compression or irritation, as in carpal tunnel syndrome. It accurately captures the patient’s reported left-hand sensation, aligning with clinical terminology for documenting transient or chronic sensory nerve disturbances, making it the appropriate term.
Choice C reason: Proprioception is the sense of body position, mediated by sensory receptors in muscles and joints, not related to pins and needles sensations. It involves spatial awareness, not cutaneous sensory abnormalities, so this term is irrelevant to the patient’s sensory complaint in the left hand.
Choice D reason: A sprain is a ligament injury, causing pain and swelling, not sensory disturbances like pins and needles. It is a musculoskeletal issue, unrelated to neurological symptoms of nerve irritation, making this term inappropriate for documenting the patient’s sensory nerve-related complaint.
