What is a diagnostic tool used to evaluate the electrical conduction of the heart and provides information on the heart rate and heart rhythm?

Choice A reason: Abdominal distention is an unexpected finding, potentially indicating serious issues like bowel obstruction, ascites, or organ enlargement, requiring urgent reporting. Unlike normal findings like symmetry, distention demands investigation. Prompt documentation ensures timely diagnosis and intervention, critical for preventing complications in patients with abdominal abnormalities.

Choice B reason: Silver striae are expected from skin stretching (e.g., pregnancy or weight gain), not typically concerning unless new or severe. Distention is more urgent. Assuming striae require reporting risks diverting focus from serious findings, potentially delaying evaluation of critical abdominal conditions needing immediate medical attention.

Choice C reason: Borborygmus (bowel sounds) is a normal finding, indicating active digestion, unless absent or hyperactive. Distention is abnormal and urgent. Assuming borborygmus requires reporting risks misprioritizing normal findings, neglecting serious issues like distention, critical for timely diagnosis and management of abdominal pathology.

Choice D reason: Abdominal symmetry is expected in healthy assessments, unlike distention, which signals pathology. Assuming symmetry is unexpected risks overlooking abnormal findings, diverting focus from urgent issues like obstruction or ascites. Reporting distention ensures prompt evaluation, critical for addressing underlying causes and preventing complications in patients.

Choice A reason: Clear bilateral lung sounds are a normal respiratory finding, indicating unobstructed airways and effective gas exchange. Abnormal sounds like wheezing or crackles would suggest pathology, but this choice reflects expected lung function, not an unexpected assessment outcome.

Choice B reason: Absence of cough is a normal finding, suggesting no airway irritation or obstruction. Coughing may indicate infection or fluid accumulation, but its absence aligns with healthy respiratory status, making this a typical and expected assessment result.

Choice C reason: Using an incentive spirometer post-surgery is an expected finding, as it promotes lung expansion and prevents atelectasis. It indicates patient compliance with respiratory therapy, a standard post-operative intervention, not an abnormal or unexpected respiratory assessment outcome.

Choice D reason: An oxygen saturation of 90% on 2 liters of oxygen via nasal cannula is unexpected, as normal saturation should be 95-100%. This suggests hypoxemia, potentially from lung pathology or inadequate oxygen delivery, warranting further investigation, making it the correct choice.
